Magic Marker: Book 1: Felt (Part 2)

Chapter 7

Susan still tensed up as she felt the marker approach the tight little butthole, wondering if maybe she was somehow wrong about the writing... if she loved it, shouldn't she want it, not be scared? But then, as it got closer, she realized... she did want it. She was still scared, but the idea of her brother pushing something up there... was exciting. In fact, the thought of it was making her slick again, making the anxious, antsy feeling that had so recently quieted build. And, as it pushed against the tight ring of muscle... instead of feeling like someone was trying to poke something through her skin, it felt more like some weird kind of massage, a bit of pressure, maybe a hint of pain, followed by a wonderful relaxing as the muscles gave way. They allowed the marker to enter, and she grunted. It felt so unnatural, something going in... but unnaturally good. And bad, in a way... because it was just so... naughty. So was what Keith was doing before, but this took it to a whole other level, going up her butt. She decided that she did, in fact love the feeling. Strange, sure, and she still had a fear that it would hurt at any moment, but until it did... she wanted more. She pushed back into the marker, or tried to... Keith's hand on her ass made it hard to move very far. Instead, she clenched her buttocks as much as she could, not trapping the marker, but almost the opposite, drawing it inside of her.

Keith had been going slow, but soon it was as far as he was willing to put it, and so he started pulling it out. Susan let out a little whiney moan, protesting, until she realized that also felt good. Like, as strange as it sounded, taking a really good poo. And the same instinctive movements that seemed to suck the marker in seemed to go to work helping pushing it out, too... like it didn't matter which way it was going, her body just wanted to help. Sending it out seemed a little more natural, but as it was leaving she wanted it back in. "Yeah, you look like you've got a good career in porn ahead of you," Keith said. "You could be a star on Anal Whores Dot Com."

The thought ran through her mind, even more deliciously naughty than a marker pen running up her ass. She wasn't as knowledgeable about the whole 'sex' thing as some of her friends, but she knew the basics, and knew that sometimes guys stuck their penis in a girl's ass. She never understood, before, how could that be appealing, either for the guy or the girl. Now, she definitely could see it from the girl's side, how good it might feel, the wrong kind of good, and began to imagine that the marker Keith was working inside her again was actually a penis... his penis, in fact. That made the thought even more wrong, which, in this state of mind, was even better. One of his hands was still on her butt cheek, holding her steady and open, and, subtly, massaging the flesh there, and that was almost as pleasurable as being penetrated. So the thought of him sticking his penis in her--an object with qualities she could only imagine, but she was a writer and her imagination was powerful--that kicked the feeling, the horniness she was becoming familiar with, into high gear. As did the thought of doing it on camera, for a porn site, not as an adult, eventually, but as she was now, which would most certainly make it illegal... but what was happening now was probably illegal, too. She was being molested. At least, that's what others would call it, but the word didn't feel right to her. 'Molested' sounded like something painful, traumatic, and this... it felt so fucking good. Even the swear word burst through her normally reserved mind. Swearing, even in her thoughts, always felt a little dirty, which isn't to say she didn't do it, or do it aloud among friends to fit in, but it was with the feeling, deep down, that she shouldn't be doing it. Now, that feeling had become so ubiquitous and so overshadowed by the pleasure that she barely even noticed anymore, thinking the word was a liberation... she was being molested (for lack of a better word) by her brother while she imagined him fucking her ass with his cock, and it felt fucking incredible.

The waves had started again, the ones that ran through her body, making it respond in any way it could to increase them, to reach that point she now knew from direct experience, the orgasm. And when Keith took his hands off her completely, the sensations almost stopped, something she couldn't bear... she reacted instantly, getting back on her hands and knees and wiggling her butt in the air, like reminding him what he'd left inside of her, or trying to get it to move in and out with muscular control alone. In fact, she did manage to move just the pen, out, bouncing it out and sucking it back in, just a fraction of an inch, before he grinned and took hold once more and started doing it himself it again, doing it much deeper and making the pleasure waves once again begin in earnest.

This time, the waves were slower, not as high, but she was better at understanding what she had to do, holding her breath when the magic marker Keith was pushing into her body went as far as he was willing to allow it, and when he pulled it out, letting the breath out in a moan, taking a shallow gasp. She squirmed, though not as much as the first time, and squinted her eyes shut, and, she suddenly realized, it wasn't just her body, her thoughts played a role, even the dirty words, and returned to the thought of Keith fucking her ass with his cock, doing it in front of her parents, or the whole school, while she begged for it, not caring that everybody knew that she loved anal stuff, and then there was a moment when it all came together, the fantasies, her ass's relentless clenching, a sudden upward thrust, and Susan holding her breath until the last possible moment, when suddenly she let loose with a cry and felt the pleasure wash over her again.

It wasn't as powerful as the first, nor did it last as long, but it was an orgasm, a better feeling than she could ever remember having without something being thrust inside of her. Now, the magic marker was still... and, to her surprise, she was somewhat relieved at that, too. She had only dimly noticed, there at the end, but it was starting to become painful... the slickness left over from her pussy, which lubricated the marker on its way in, had worn off, and the friction had started to build up to an uncomfortable level. If she had gone any longer, the repeated sawing motion might have started to really hurt.

Instead, Keith removed it entirely, which she wasn't sure she wanted either, but he didn't give her much choice in the matter. She opened her eyes and looked up at him lazily, and he had that jerky, smug smirk on his face again. Keith shook his head, and said, "Unbelievable the lengths you'll go to, to convince me something's magic... you took a pen up your ass! You are soooo going to be a slut when you start dating."

She glared at him, but didn't feel like she had the strength to do much else. "It is magic." He put on a face as he nodded, like he was agreeing with her, only sarcastically. "If it's not magic, why not give me the pen?"

"Because I'm not going to feed your delusion. Besides, this is my pen." He lifted it to just under his nose, took a whiff, and made an exaggerated face that made Susan blush. "Though I do need to wash it. Your butt stinks worse than your feet. You want me to help you out again, there better be something in it for me." He slapped her butt, lightly, one last time, and stood, heading out the door. She noticed something hard poking against the front of his boxers from inside, tenting them outwards, before he turned and walked out. She heard him running water in the washroom, and imagined him washing down the marker, and then retreated into his room and closed the door.

Not long after that, she heard his music blaring, and, only then did she trust herself to try to get to her feet. She no longer felt as weak as she had right after the orgasm, and, although her legs wobbled a little the first few seconds, even managed to stand.

It felt funny. Like her butt had been changed forever, like it was missing something. Susan wandered to her mirror, bent over in front of it, spread her cheeks with her hands, and tried to look at it... it did look red, and swollen, and... ready to open. Not actually open, but, before she'd looked at it and it was like the face of someone who just sucked on a lemon... now, it was almost like somebody blowing a kiss. She flexed the muscles there and watched it open slightly.

She then turned and looked at her pussy... the blood, that didn't seem to be coming out any more, though pussy did also seem redder inside, and there were smears of red outside. She wasn't a virgin anymore... or was she? She hadn't actually had sex, but she'd lost her cherry. Did that count? She didn't think it should, but sex was full of weird rules she didn't fully understand. She even got conflicting information on what the 'bases' meant... first base was kissing, but after that, nobody she'd talked to seemed to agree. What had just happened might be second or third base or some kind of foul ball.

Her eyes drifted to the humiliating words still written on her. Even reflected in the mirror, they made her blush. She was now, for the next week, going to be super horny, and love anal stuff. That was going to be difficult... the horny one most of all. She guessed that, even if she loved anal stuff, she didn't actually have to DO it if she didn't want to. The words only controlled how she felt about it. And she loved going swimming, but she could go months without doing it. But the horny one... that feeling was hard to resist. If she could wipe away one, it'd be that one, but she couldn't.

Or could she? It had only been minutes since the words were written on her... maybe the marks hadn't set in yet, and she could wash them away. When Keith wrote on her suddenly smelly feet, she didn't try scrubbing the words away for several hours, and that was certainly too late... but if she hopped in the shower now, there was a chance.

She'd just had a shower, but there was no reason she couldn't have two. The decision made, she began to lay out some fresh clothes, because the ones she wore today now seemed somehow dirty... the panties especially, but it didn't seem right to wear the same shirt, either even though she'd only wore it for a few hours. It was like what had happened before the orgasm was a completely new day for her. New day means new clothes. So did a shower.

Once she'd chosen what she'd wear after she got out, she retreated to the shower, turned it on as hot as she could bear it, and started scrubbing her back area with the bar of soap. There was a moment of excited hope when it seemed the water streaming down her feet was discolored, and she thought it might be the ink washing away... and then she realized it was just some of the blood, coming from inside her, and targeted the spray to get rid of as much of it as she could. There seemed to be a lot of it... far more than there should be for the short amount of pain, but just when she was starting to worry that there might be something permanently wrong with her, it tapered off, the water became clear again, and she went back to trying to wash away ink.

She couldn't tell for sure until she looked in the mirror, but it didn't seem like it was doing much good. Was she super horny? Not right that moment, but did 'super horny' mean she would always be super horny, or that she got super horny? She didn't know. What about loving anal stuff? She slipped the soap between her butt cheek, washed the anus, and felt a shiver of excitement. Yes, if the soap wasn't too big, she'd probably try to push it all the way inside. As it was... she could soap up a finger and send that in.

The idea excited her and before she knew it, she was doing just that, sending one slippery finger inside of her, which she slid in and out, telling herself at first she was just doing it to clean herself... Keith had said she was stinky, and what better way to clean the inside of her butt than with a soapy finger? It felt good, too, maybe not as good as the marker did, but she could wiggle the finger around and make herself squirm, like if you could actually tickle yourself, although not quite. What she thought would be really cool was if she could find something to stick up there and leave there, something that wouldn't fall out on its own but she could take out whenever she needed to. It was too bad nobody else would think of something like that... the idea really tickled her, that she could walk around, even in public, and every time she moved it would move too and provoke these little bursts of pleasure, maybe even getting an orgasm with nobody else realizing it... she realized it was happening again. Her knees were weak and shaking and the all-out horny feeling had come upon her like a tidal wave, sudden and irresistible.

She pulled the finger out defiantly. No. She might love anal stuff, but she had to get a handle on this. If she was going to be super horny this often, she had to find a way to control it, otherwise she'd be putting things in her butt at the dinner table in front of her parents by the end of the week!

Boys are super horny all the time, she remembered again. How did they deal with it?

They masturbated, of course, which girls could do as well (did sticking things in her butt count?), but that couldn't be the only way. What if it happened to them in school? She remembered a boy in her class walking with his schoolbooks over his lap, and her friend whispering in her ear that he had a boner, and the two of them giggling like mad. What did he do?

She didn't remember. But what she DID remember was something else, a sitcom she watched months ago, where for some reason, the guy wasn't allowed to have sex... and, so, of course, that was the time several different girls started aggressively hitting on him, one even whispering in his ear what she wanted to do to him... that was left to the audience's imagination, and, for sexual situations, she didn't have much at the time, thinking it was mostly kissing and maybe letting him grope her boobs... but what she did remember was his reaction. They made a running joke of him going into the bathroom and taking an ice-cold shower, or jumping in other cold water.

She turned and eyed the knobs for a moment, and then, sucking in a breath, turned the hot water all the way off. It took about three seconds, and then suddenly she was drenched in ice cold water that seemed like it made her entire skin shrink, dragging her entire body along into an awkward pose, a few steps out of the stream. She wanted to yell, but she couldn't seem to find the breath, all she had was exhaled in a puff as the first chilly blast hit her, and since then she wasn't able to breathe at all.

She was, however, no longer super horny. So, that was something.

Bending back into the spray was almost painful, and when she leaned forward to turn it off, she kept drawing back before she got to the knobs, but finally took a breath and forced herself through, pushed the little switch that turned the water flow from the showerhead to the faucet, and then quickly turned the water off entirely.

Susan's teeth chattered comically, and she gingerly stepped out of the tub and wrapped herself in a towel, wiping herself down quickly and then draping it over her shoulders like a cloak. She wasn't sure what was worse, horniness or the cold... but at least she had a starting point. If she got too horny, she could use cold water. Were there other methods? She remembered something about picturing something disgusting, she could try that, although she would have thought she'd find sticking something up her butt disgusting, so it wasn't a sure thing. Or there was thinking about baseball, which, though she wasn't sure, she also thought was supposed to help for that. She guessed it was probably anything boring that would work. So there were things she could try, would try.

Unfortunately none of them helped for very long.

Chapter 8

The shower worked for a while. Distracting herself worked for a while. But, nearly a half hour later, after she was in her fresh set of clothes and watching TV in the family room, Susan came to realize that she'd distracted herself so much, that she'd unbuttoned the top button on her shorts and been rubbing her pussy through her panties without even being consciously aware of it. She only noticed it when she scratched her face with her hand and realized it left a wet spot. She then pulled her shorts down and looked down... her white panties were soaked and practically see-through, clinging to and showing off the area around her crack. And then she realized she was horny, and had been for a while... she'd been able to push it out of her mind, but not, apparently, out of her body. And now that it had gotten into her mind, it was all she could think about.

The problem, she decided, was television. It must not have worked as a distraction, because she wasn't really doing anything, the passive staring at a screen let her mind wander, and daydream... her thoughts had flit from hot boys on the screen, to what had happened earlier in the day, and all of that had slowly let the horniness creep in. The truth was, she'd only thought she'd been watching TV. She couldn't actually remember the plot of what she was watching.

"I need to do something else," she said aloud as she hurriedly pulled her short back in place. Something else, something that would use her brain actively enough that there was no room for the horny thoughts. She headed up to her room, where, upon seeing her bed, felt an unexpected rush of memories of the morning. Those she pushed out of her mind, thinking about baseball... or, were she to be honest, just muttering the word "baseball" over and over again, like a prayer.

If school was in session, she could probably lose herself in homework... never before would she have imagined hoping for homework during summer vacation, but, here she was. But even without homework, there was something else that was almost as good at absorbing her attention, but a lot more fun. Writing.

Her life goal was to be a famous writer, and she loved making up stories, a lot of them involving the characters she saw on TV or read in other stories, but some of her own creation (most of the main characters in these were not-very-well-disguised versions of herself with superior abilities). Writing turned out to be much harder than making up the stories, but she still worked at it regularly, and her computer was full of half-finished works.

The work of writing wasn't like TV, it took up all of her attention, so she opened the story she'd most recently been working on, and started typing. It only helped for a few minutes, and then she realized when she wrote her two favorite characters starting to fall in love (a frequent theme in her stories), it no longer involved kissing and making out, quickly they were stripping each other down and one was putting his finger in the other's pussy, and she imagined more, things she'd seen in porn, and her own pussy felt like it was sweating lava.

Maybe, she decided, what she needed was another orgasm. That helped for a little while, and maybe people had a certain number they could have each day, before they no longer could get horny. If that was true, then the thing to do was to get most of them out of the way as soon as possible. She resumed rubbing of her pussy, this time consciously, and looked around... touching herself was feeling good, but... was there something she could use, something she could stick inside her, make it feel even better?

Why not ask Keith?, she thought suddenly. He was better at it than she was. Whenever she touched herself, she was hesitant, like she was afraid it was going to hurt, or she chickened out when it started to feel too good. Keith didn't have that problem, he was, she'd discovered, good at causing orgasms. And she was not just horny, but super horny... so this was all his fault.

He'd even offered, it, sort of... he'd said she'd need to do something for him, but that wasn't a 'no,' that was a 'yes, if he got something he wanted.' She could maybe take on some of his chores or give him some of her allowance...

She tiptoed to his room and knocked on the door. When he opened it, he was dressed in a t-shirt and jeans, and looked down at her with a smirk. "What?"

"I'm... I'm horny again." She looked up at him. "Super horny."

The smirk widened into a grin. "Really. And I suppose you want me to take care of it?"

"It's your fault," she insisted once again, but knew it was no use. He was so stubborn, he'd probably need a winged horse to fly in through the window before he'd admit magic existed.

"God, you are so gullible."

"Are you going to help me, or not?"

He opened the door and stepped aside. "Get on the bed and take off all your clothes," he said.

She brushed past him and climbed onto his bed on all fours, and then rolled over to sit in the middle. Keith closed the door, locked it with a click, and sat down at his art desk. She saw him grab a pen from the desk... and she wasn't sure, but she thought it might be THE pen, the magic marker, the one that put Susan in this position. At least it looked like he wasn't going to demand anything... aside from taking off her clothes, which seemed like a fair thing to ask.

It was embarrassing though... this wasn't like that first time when she was so overwhelmed with the new sensation of horniness that she stripped down with barely a second thought. This time she was used to the sensations, had her wits more about her, and so she thought about how weird it was to be stripping naked in front of her older brother, and the way he watched her, no expression on his face, but with those hungry eyes.

She pulled off her shirt first, and then looked down at herself... her nipples were all poked-out again, and her thighs clenched as she remembered him pulling on them. That action, and the accompanying feeling, reminded her how eager she was for an orgasm, and so she pulled off her shorts and panties as one. Her pussy was wet and flushed... she was starting to get used to that feeling. Unprompted, she got on her hands and knees, pointing her butt in his direction, giving him easy access to both holes.

"Did I ask you to do that?"

"No, but..." She bit her lip. "You're going to do it, right?"

"Sit on the edge of the bed, first." She changed position, sitting exactly as he asked, and then tensed up as he reached down to rub her pussy with his fingers. It was so much better than the feel of the marker, the fingers could flex and move in unexpected ways. She closed her eyes and leaned back, holding her body up with her hands set behind her. "Yeah, you really seem like you need it."

She nodded hurriedly, made an 'mm-hmm' sound. She really did, it felt like she might burst if she didn't... which was kind of funny, when she thought of it, because when she got the orgasm, it sort of felt like she had burst, but one burst was what she wanted and the other burst seemed like something she had to avoid at all costs.

"Then you've got to do something for me, first." Her eyes snapped open, just in time to see his hands go to his pants, which undid the button and zipper, and pulled down the boxers, which looked to be barely able to contain some monster inside, until the monster was freed, revealing it as his penis, the first real, hard penis she'd seen in person. She stared at it in fascination, it feeling somehow more intimate than when he stared at her, it was a hard, bouncing thing, with a glistening head and seemed to almost vibrate gently, like it was full of a life of its own, and a little threatening, the way it poked out towards her, but exciting, too. Did he want her to touch it? "You're going to learn how to give a blowjob..." he said.

That got her attention and cut through the horniness some, less successfully than a cold shower, but still, it was something she hadn't expected... should have, perhaps, but didn't. Firstly, because she never understood how girls did that... it just seemed so gross. Sure, so did sticking something up her butt, but she loved anal stuff now, and it felt good... sticking something in her mouth only felt good if it tasted good, and she couldn't imagine that. She didn't even like sucking on her fingers. But even if she could get beyond that... it was oral sex. That was a kind of sex, technically. What had happened so far, wasn't, as far as she could tell. Keith might have done something dirty, but she hadn't. There were lines, and then there were LINES. "No," she said, defiantly, brushing her hair out of one of her eyes again. Although, as she said the words, deep down a part of her wanted him to convince her.

He seemed shocked. "Why not?"

"Because it's gross. And you're my brother. I'm not, like, sucking you or whatever."

"Oh no? You think you're too good to put my cock in your mouth?" He grinned, and dangled the marker, the magic marker, in front of her. "Then it's time to play my new favorite game... try and prove Susan wrong. Let's see how far you're willing to go this time..."

He pushed her down, roughly, although without hurting her, just sending her sprawling backwards, then uncapped the pen and, with the hand that held the cap, grabbed her right leg and pulled it upwards, making it difficult to move, at least not without trying to kick wildly at him, an action she was unwilling to do. In fact, she was unwilling to try anything, as her heart pounded and she waited for what new words would be marked on her skin, inscribed onto who she was for the next week.

He wrote it on the inside of her right thigh, two words, and then let her leg drop. She rested the ankle of that leg on the thigh of her other, so she could better inspect the new words. "Cock Sucker," it said. That's what the writing said, and, seconds later, that's what she became, in the most direct way possible, the moment his dick got close enough, she opened her mouth and wrapped her lips around it, and began to bob her head up and down, gently sucking.

Chapter 9

She didn't like it... it was like a warm sweaty popsicle, about as bad as she'd imagined... but she was a cock sucker now, which, she guessed, meant that she must suck cock. In fact, as she went down on her brother for the first time, she told herself to pull away, but she couldn't. Maybe she could have, physically, but she just couldn't seem to raise the will to pull away... as disgusting as it was, she didn't want to stop sucking the cock, she just wanted to want to stop, wanted to not be the type of person who wanted to continue. But while she wanted to want to stop, she drew up to the bulbous head of the penis and, without breaking contact, ran her tongue underneath, provoking a groan from Keith. "You've done this before, haven't you?"

She blushed and shook her head, pulling his dick from side to side with her mouth as far as it could go, and made a noise that sounded like denial. Of course she hadn't... how could he even think that?

"Well, then you're an absolute natural at this," he said softly, and that she actually did like, even though she wondered at it, how she could be good at something she'd never done before. It must have been the pen.

During her first blowjob, that was what was running through her mind, the nature of the magic in the pen. In some ways, it was like writing itself. There was a power in words, beyond the words themselves... the structure, the context was important, and, she decided, words carried meanings, meanings that weren't always obvious. An absolutely literal translation of 'cock sucker' might have become true with the first time she sucked. If he'd written 'baker', Susan guessed she would know how to bake, maybe not well, but well enough to be a baker... but the knowing wasn't enough. She had to do the act. And is a baker still a baker, if they decide never to bake anymore? She guessed not, otherwise she'd be able to stop sucking the cock. Every person who had ever baked would then be a baker, and every woman who had ever sucked cock would be a cock sucker. If you became a baker, or cock sucker, just from doing it once, the words wouldn't really be meaningful... for the words to mean something, it had to be more than just the boring fact of having done it. So a cock sucker, which she would be for the next week, had to mean somebody who currently chooses to suck cock... but how often? Every day? Every minute? Would Susan somehow be finding a way to suck Keith's cock for the entire week? No, she didn't think that would be the case... just like she had short periods when she wasn't super horny, and those words were still, generally, true, she expected she wouldn't have to suck cock all the time... just often enough. Whatever that meant. She seemed to get horny at the slightest opportunity, though, and maybe this was the same way... when she was a cock sucker, she'd suck cock at the slightest opportunity. Any time it looked like she could suck cock, she would. And right now, she could suck it uninterrupted. Maybe that meant it would last until Keith told her 'no more'.

The thought sent a shiver up her spine, followed by a pulse of warm, electric pleasure... the lack of control felt good, she would be almost a slave to his whim. It was oddly liberating, not in the usual way, because she wouldn't have the liberty to decide what to do, but it was something of a relief to not HAVE to decide, ever. And also, the thought of doing it whenever he wanted, it was just so dirty... as was the knowledge that she'd probably thought the word 'cock' more in the past minute than in her whole life before, all while having a cock in her mouth. She was behaving like a complete and total slut. Her hand automatically went down to her pussy to explore the feeling, expand it, maybe bring on the orgasm herself, even though part of her wanted to hold off, wanted Keith to do it... then again, maybe he was, if it was his cock in her mouth making her so horny. "You like that, huh?" Keith asked, probably noticing her starting to masturbate, and, because she couldn't take her mouth off that cock, she couldn't answer him, but she made a sound, something like a mm-hmmm, because even though she didn't like the taste or feel of the cock in her mouth, somehow she really liked that she was doing it, doing it for her brother of all people. It felt naughty, grown-up, forbidden, and overwhelmingly hot. And when Keith grabbed her short hair and pushed her down deeper on him, sending his cock far deeper than she'd been going so far, it felt even hotter.

Despite the added discomfort, she handled it without worry, and from that point on, would go down to that length every so often, since he seemed to want it, and what kind of cock sucker doesn't do what the guy wants? Although Keith would sometimes guide her roughly when he wanted her deeper than she was planning, most of the rest of the time, his touch seemed gentler, playing with her hair, rubbing the side of her face with a sort of tenderness that lifted her spirits. She was making him happy, and she liked that... if she made him happy enough, maybe he wouldn't be a jerk to her anymore. Still a jerk, at least as long as the mark was there, but not to her... that would be a win. She could only hope she was making him happy, the signals his body was giving off didn't suggest that, but she remembered her own body had some of the same ambiguous effects when she approached her own orgasm. His breathing began to get tense, strained, getting shallower and louder, and then, in an instant, the tender touch became a tight grip on her hair, not forcing her deeper, but telling her not to move right where she was, about halfway down.

That was when Susan became aware her brother was squirting something in her mouth, something thick and bitter, even worse tasting than the cock itself, a jet of it bounced off her tongue and seemed to hit the roof of her mouth, another missed and seemed to go into the back of the throat, forcing her to swallow it just to feel like she wasn't choking. She thought she should pull her mouth away, wanted to not have to taste the gloopy mass filling it, but she was a cock sucker and that was more important than any of those concerns. She continued sucking, swallowing as best as she could.

Keith exhaled sharply, and she noticed his cock was becoming softer and smaller, easier to suck, and except for the taste, almost more fun, it was no longer rigid and she could move her head side to side more and swirl her tongue around it, which she did until her brother pushed her away, and she finally made a face... but her eyes were still focused on that cock. The urge to put it in her mouth again was overwhelming.

At least, it was until he tucked it back into his pants, and then it subsided almost completely. So was that the rule, she wondered? Was that what made one a 'cock sucker?' Whenever she saw a cock, she'd feel an urge to suck it? If so, that wasn't so bad, this was the first one she'd seen in person in her life, so it obviously wasn't going to happen very often. Which was good, because the taste really was awful... as she moved her tongue around in her mouth to try to clear it away, she ran into a huge glob of it she'd missed swallowing, and made a face. Though, she supposed that if she liked it, it wouldn't have made a good enough exchange to get what she wanted from Keith. Remembering what she came in here for in the first place, she asked, "So are you going to help me now?"

"Fine. Get on your back. Because you did such a good job, I'll give you the Shocker."

Susan, who was practically aching from being horny so long with only the mixed relief of mild masturbation, scrambled to follow his instructions, before finally asking, "What's the Shocker?"

He held up three fingers, the index and middle finger, and his pinkie, with his ring finger folded down. "Two in the pink," he said, and started to wiggle the pinkie. "And one in the stink."

She still didn't understand exactly what he meant, but thought she got at least part of it. "You're going to use your fingers?"

"Relax, you'll like it," he said, and she did, laying her head down passively, and waiting for him to get closer. He was probably right, considering she was super horny, and loved anal stuff.

It started with him not doing the Shocker, whatever that was, but just running his palm up the whole length of her pussy, grabbing it, kneading the flesh from bottom to top. It would stop at the hole and swirl around, getting his fingers wet and making Susan twitch with the delightful agony of something so close to, but not quite, what she wanted. After a few swipes of this, he did much the same with the back of his hand, rubbing her with his knuckles.

Finally, she saw him make the weird hand shape again, like he was pointing a finger-gun at her pussy (for the pinky was now out of sight), and he pressed forward, widening the entrance as his two fingers pushed inside her, and she gasped suddenly as, just as she was getting used to that feeling, there was a sudden, delightful pressure on her asshole, the unseen pinky finger. It too was forcing its way inside, and Susan did that unconscious muscle twitch to try to open herself down there, and soon, three fingers were deep inside her, two in the pussy, one in the ass, driving her wild. She changed her mind in that moment, fingers were much better than a magic marker, at least if they were somebody else's. The warmth, the pulse, the unexpected wiggling. Even though the pinky in her butt was smaller than the marker, and she might have preferred something larger, that was only a minor drawback, and, as she was already so close, she had an orgasm within a minute.

The Shocker treatment continued all through the orgasm, and even after she came down, like Keith was going to try to give her two, or maybe he didn't realize she'd had one yet. She didn't want to tell him, either, but then discovered he must have already known, for he said, smugly, "See, I told ya you'd like it." She just breathed heavily, trying to re-center herself, an instinctive feeling she couldn't have another orgasm until her mind had completely settled down from the last one. "Just like you enjoyed sucking my cock."

"No I didn't," she said, despite her mixed feelings about it. There was the taste issue and, besides, if Keith thought she completely hated it, she could trade it for orgasm service. If he thought she'd enjoyed it, he might make her do something else.

"You sure seemed to like it to me. You were sucking on it like it was a candy and you couldn't wait to get to the creamy center. I had to practically wrestle it out of your mouth."

It was useless, but she had to try. "Only because you wrote it on me and made me a... 'cock sucker'. I didn't want to, I had no choice."

"Sure, sure," he said in that dismissive way.

"I didn't!" she insisted. "And it tasted nasty. I never want to have to taste it again."

"Oh, I bet I could change your mind about that," he said ominously, and she knew that he could, if he wanted to, if he believed in the magic. But he didn't say anything more about it, just continued finger-banging her with the Shocker, playing her like an instrument, and, within a few minutes, she experienced another explosive orgasm, again, not as powerful as the first, but this time, as she was going through with it, he jiggled his hand forcefully, giving her a strong sensation to cling to beyond the timeless empty pleasure, and that seemed to make it last longer. "Too bad you don't do an ahegao face," he said, pulling his fingers out the moment she settled back into her deep breathing phase. She didn't know that word. "Maybe we can fix that later. But for now, you can get out of my hair." He stood, and cupped his crotch with his hand. "I've got some drawing to do, and it's going to take a while to build up another load for you to suck down."

"Eww," she said. "I don't want to do that again. I told you, it tastes nasty." She wasn't ready to move yet, either.

"Hmm," he said, and looked down at the magic marker... he'd had it clutched in one hand or another through the whole affair, the blowjob and the Shocker, as though he was afraid she might try to steal it... maybe she should, she decided, because it was clear he was getting an idea. "Let's see if we can fix THAT then."

He grabbed her foot, her left one, and hefted it into the air, got the cap off, and began to write. This time, Susan didn't even want to attempt to struggle. After all, if he somehow made her like the taste, that was a good thing, wasn't it? So, she let him write it, and, when he let go, roused herself to take a look. At first she was pleased, but then realized it wasn't as good as she first thought. "Addicted to cum?" she read, her voice incredulous. Good grief. "Couldn't you have written 'Likes the taste'?" Her first instinct was that it was the same thing, but she remembered people on TV talking about getting addicted to alcohol but hating the taste. And she imagined smokers couldn't like how cigarettes tasted, but they were addicted all the same.

He shrugged and grinned. "I guess I could, but this way's more fun. Whassamatter, started jonesing for it already?"

"No!" she snapped, and then realized... it was true. She hadn't.

Keith also looked a little puzzled, but finally said, "See, I told you there was nothing magical about this."

She wondered again if maybe she was making it up, not consciously, but just believing it so much she acted like it was true. Because, judging by the other times she was marked, she really should be addicted by now. Unless... it came to her then, all at once. "Yeah, but I just had a... dose, or whatever," she pointed out. "I might be addicted, but if I just drank some..."

Her brother relaxed and lightly slapped her thigh... not even really a slap, this fingertips just grazed the top. "Then come see me when you need another dose. If you need another one. Until then, scram." He went to sit at his desk, and made a big show of ignoring her. Susan took her time and got dressed again there in his room, wanting him to acknowledge her, say something, maybe apologize, tell her he loved her, but knew it was impossible... he was a jerk, and that was all her fault. At least the horniness had gone down, for the time being. When she had all her clothes on, she turned tail and left without a word. It was only after she left that she looked down, and saw that you could see the letter "Coc" and "Suck" poking out the bottom of her shorts, if she turned her legs the right way. She sighed to herself... she couldn't wear short shorts any more, to completely cover up the letters, they'd have to come down to just above her knee.

Chapter 10

It was hard to say which came first, the next bout of super-horniness or the cravings, but the cravings caught her conscious attention first, and, a little after noon, Susan found herself wandering over to the fridge. Lately, for lunches, she'd been overdosing on Peanut Butter and Jam (or sometimes Jelly). When she had to go to school, she wasn't allowed to bring them, because someone in her class had allergies, and she couldn't have them for dinner, so they were something of a rare treat most of the year. During the summer, she made up for lost time, and there were whole weeks where she had nothing but.

This time, though, when she opened the fridge, instead of grabbing the jam, she found herself pulling out the mayo. When she put it on the table she stared at it a moment, and then shrugged, deciding that she must have been in the mood for a ham sandwich, and assembled one, with a good dollop of mayo... and she stared at the butter knife coated with leftover white stuff, and thought of the white goo that came out of cocks. She hadn't actually seen it on Keith, since she was too busy sucking his cock at the time, but she had an idea of what it looked like... somewhat of an idealized, cartoonized idea, where it was goopy globs of bright white that looked much like mayonnaise, and so, when she saw it on the knife, she found herself licking it directly off the blade. The taste wasn't the same, not even close (mayo was better, but still a little icky by itself), and it was cold, but she licked it clean anyway before realizing what she was doing and had a guess at why, then shuddered.

When she got the sandwich to her room, she started reflecting how, when you combined it with the salty ham, the mayo did taste a little more like what Keith had shot in her mouth, although more palatable than either cum or mayo alone, and began picturing herself eating a sandwich that her brother had cum all over the inside... which got her horniness up again, which made her think even more about sucking cock in exchange for another orgasm, until she finally chastised herself. She shouldn't be enjoying what was happening, being molested.

No, she thought again. 'Molested' sounded too harmful. It wasn't the right word, she needed to find another. There was supposedly a famous writer, her teacher couldn't remember which, that said something Susan tried to use as a motto in her writing, even if she was sure she failed at it most of the time. He or she said (Susan guessed it was probably a she, maybe Jane Austen), "The difference between the right word and the almost right word is the difference between the lightning bug and the lightning." 'Molested' was almost right, but not exactly, and so it was wrong. She needed the right word, one that captured how, even though it wasn't entirely willing, she liked it, kept thinking about it, even craved it, and not just because of what was written on her skin. Keith wrote that she loved anal stuff, but hadn't written anything about her enjoying the feel of his fingers deep in her pussy, so that had to come from her. She wasn't being molested... she needed a word that captured the lightning, not the bug. But what other word was there? Maybe it was beyond words, just one of those things that nobody ever talks about. Lots of people don't even talk about being molested, if what teachers said was true.

The only time she personally knew someone who did talk about it, they didn't even actually use the word 'molested'. It happened when she was ten, and there was a big stink at her school when a girl claimed she'd been felt up by the soccer coach during a field trip. Those were the words she used, 'felt up', and at the time, Susan thought that was a strange turn of phrase, because it was supposed to be bad, but it didn't sound bad. If you were feeling down, being 'felt up' sounded like a good thing, didn't it? The girl moved away shortly after, having been discredited for, she'd heard, having accused lots of other people of doing it to her, and nobody really believed her because, whenever she talked about it, she sounded just vaguely annoyed rather than traumatized like everyone knew you were supposed to be when some creep tried to touch you in one of your private places. Now, Susan wondered if maybe it happened, maybe the reason she wasn't in tears was because she partly enjoyed it... she wasn't molested, she was just felt up.

Now, so was Susan. In fact, Susan hadn't just been felt up, she'd been felt down, and felt inside... and that felt like the perfect word, because she now felt thoroughly 'felt'. And it felt great at the time, leading to something else she'd never felt before, orgasm. All because of the words written on a felt-tipped marker. She licked some mayo off her lips, finished her sandwich, and ran the hard edge of her plate between her legs... yes, that hardness rubbing against her slit, through her shorts, was a nice sensation, but it was nothing compared to being 'felt' by another human being she cared about. That was definitely the right word. Enjoying being molested would be crazy, but it was okay to enjoy being felt, to crave it again, to ask the person doing it to feel you again.

She headed downstairs to put her plate in the sink, went back upstairs, and knocked on her brother's door, ready to get felt some more, and to sate her cum addiction. He didn't answer, so, while Susan waited, she decided to save time and strip down there in the hallway. When he still hadn't answered by the time she was nude, she knocked again, more loudly.

Keith appeared at the door, towering over her, and looked down at her naked body with a smile. "Again?" he asked, and shook his head in that way he had, then held the door open for her to enter. "Looks like you're raring to go."

"It's your fault," she said listlessly, no longer expecting it might be believed. If he'd just admit it, she could forgive him and focus on the fun of being felt, but he never would, especially not while he was a jerk.

"Keep telling yourself that, you little slut," he said. "So, do you want the Shocker again, or do you feel like something bigger?"

Her lip trembled. "But... don't you want me to suck your..." She could think the word, but saying it was still a struggle.

"My cock?" Keith supplied, seemingly having no trouble. In fact, he seemed tickled pink. "You want to suck my cock?"

"No," she lied, or half-lied. She still suffered seriously mixed feelings over it. "But I'm addicted, thanks to you."

"Is that so?"

"Yes."

"Well, maybe I'm not interested in a blowjob right now," he said.

Her heart dropped, and then started racing. "You're not?" she asked in a wavering voice. She'd expected he'd jump at the chance, and now... she hadn't realized how much she was counting on it until it was denied. "But... but..."

"Maybe if you begged me," he suggested, his voice raising at the end of the offer.

She didn't like begging, but... she really felt like she needed it. "Please," she said. "Let me... suck... let me suck your..." She blushed... why did she find it so hard to say dirty words out loud?

"Go on, say it..."

"Letmesuckyourcockplease?" she spat out in a rush.

"No," he said, and she wanted to die, or smack him. "Not if you're not going to beg properly... don't you know anything? You're supposed to do it on your knees."

She fell on her knees, clasped her hands together in front of her face, and tried again. "Please, let me suck your cock." The second time was easier.

"You like my cock, huh?"

"Yes," she agreed, knowing a more honest, nuanced answer would just make him deny her for not begging enough. "I love it, please, I want to drink your cum." Cum wasn't as bad a word, since she could pretend she was saying 'come.' Of course, you could also 'cock' your head or a gun, and a 'cock' was a male rooster, but that didn't seem to matter, when she was saying 'cock' there was only one thing in her mind.

"Oh, all right, since you're already on your knees..." He undid the top button of his pants, which were already unzipped, and pulled out his cock, already hard. After that, she didn't have any choice in the matter... she was a cock-sucker, and one who was addicted to cum, to boot. She took it in her mouth, and she proceeded to suck. To her surprise, it tasted better, although she couldn't put her finger on exactly how. It was a number of little details... the sweaty flavor underlying everything didn't taste so much like sweat, the whole thing had a more meatier taste in her mouth, and the tip, when she ran her tongue around it, was less bitter, more flavorful. She actually enjoyed doing that and, judging by her brother's 'mmm' sounds, he enjoyed her doing that too.

"If you're not going to go far down," he said after she did it for almost half a minute, "you should stroke it with your hand, too." She complied, wrapping her hand around the shaft, enjoying the warm feeling, and how the pulse of it felt much stronger. Her hand pumped up and down along it and, when her hand was towards the bottom, she went down on him as far as she could, feeling him touch the back of her throat, which she thought would make her gag, but didn't.

Finally, she got her reward, and although she predicted it in advance by the way his breathing changed, and although she dreaded the taste, she could not pull off, she needed her dose, and she was still a cock sucker. His cum rolled over her tongue and, to her surprise, it also tasted better, much better, almost buttery... buttery, salty, a little meaty, not very bitter at all. The texture was still a little gross, slimy rather than a smooth liquid or solid, but the flavor was good. Good, but the kind of good where you think you could easily get sick if you ate too much of it. Kind of like the fatty part of a pork chop. However much 'too much' was, it was more than Keith produced, so Susan swallowed it all eagerly, and even made her own 'mmm' sounds. It must have been her addiction, she decided, making it taste so good, and indeed, swallowing it also made some of the anxiety disappear, leaving just the horniness she'd been growing used to. Now she was ready for the Shocker, or something bigger, which might have just meant using the marker again, or maybe something like a brush, but there were other ideas that excited her even more because they were just so wrong, even wronger than everything else they'd done so far. But even a jerk wouldn't try to have sex with his sister, would he? And even if he did, should she try to resist? Or make him wear a condom? If he wore a condom, she thought, it wouldn't really be that bad... their privates wouldn't actually be touching, it would just be like he was touching rubber, and she was being felt by rubber. Or whatever condoms were made of, latex probably.

"You really seemed to like it that time," Keith said, pulling his dick from her mouth and allowing her to, temporarily, at least, put her cock-sucking nature on hold and take a breath.

"Because you made me an addict."

"No, the marker did nothing, you just liked it," he said smugly, and, just as Susan was thinking that they would never be done with this argument, he added, "And I can prove it."

That was new. "How?" she asked, but doubtfully... she knew the power of the marker, she felt it.

He rolled up his left sleeve. On his inner bicep he had written the word "RICH." "See? I wrote this a few minutes after you left the last time."

"So?" she asked, even though she knew what he was getting at, she just needed time to think... there had to be an explanation. This couldn't all be in her head... could it?

"So, am I rich yet? I don't see any solid gold statues, my bank account's still in the low double digits, and my wallet's almost empty. Unless Dad won the lottery at work, there's no magic in this pen. You sucked my cock because you wanted to. You're a little slut, you're a little slut..." He said the last in a little taunting sing-song voice as he pointed at her.

"There is so magic..." There had to be.

"Then why aren't I rich?"

She made a face, and then said, "Let me see the marker."

He looked hesitant at first, but went to his drawing desk, retrieved the pen, and handed it over. "You even try to uncap it and you'll wish you never found it."

"I already do," she said, but, the truth was, she didn't... she knew she should, but she didn't. That didn't mean she loved everything that had happened, but some of it was good. If only she could make her brother less of a jerk... and, with the pen in her hand, that was a possibility, but not much of one. She had no doubt he'd be able to wrestle it out of her hands if she tried to write on him, before she got a single letter down. Instead, she just read the long disclaimer written on the side, until she found what she was looking for. "See, look here! 'Ink Will Not Alter Anything You Don't Write On!'" He took it from her and read it for himself. "Being rich isn't just about you. If it was going to make you rich, it'd have to change your bank account, or put money in your wallet directly... and that would probably violate the laws of physics or something, too." Wasn't one of them that matter and energy couldn't be created or destroyed?

"Well, you've just got an excuse for everything, don't you?" he snapped. "Isn't that one of the sure signs of a delusion?"

That made no sense to Susan, so she didn't say anything... directly challenging him was only likely to make him mad, and while he was a jerk, she didn't want to do that any more than necessary. "So are you going to feel me now or what?"

"Feel you?"

"You know, feel me up," she put her hands above her breasts, or where they would one day grow, then dropped it to her pussy and continued, "feel me down... I'm still super horny because of you."

"I don't know," Keith said. "What's in it for me?"

Susan gritted her teeth and tried, unsuccessfully, to keep anger out of her voice when she pointed out, "I just sucked your cock." At least she was getting better at saying it.

"Yeah, and begged me for the privilege. So I was doing you a favor, or at least we came out even. You want me to help you out, I'm going to need something else."

Chapter 11

Susan could hardly breath. "Like what?" she managed to ask, regardless, as her heart started pounding. Once again, he'd told her he needed her to go one step further before he'd help her with her horniness. Could she have been right about what he meant by 'something bigger', and this was his way to manipulate her into doing it? If not, what else was there? Would he want to do more to her than he already had? It had to be sex, didn't it?

"I'll do it," he said finally, and then added, "but you gotta let me take some pictures."

Her eyes widened at the unexpected request. "Pictures?"

"Yeah."

"Of me?" A warm rush of blood went to her cheeks... it was flattering, wasn't it?

"Yeah, mostly for reference."

"What?"

"You know, to help my drawing... especially if I want to do hentai..."

"What's hen tie?" That was how she visualized the spelling, anyway, and guessed maybe it involved tying her up. Or maybe it was 'hand-tie', and he wanted to practice on drawing hands... he certainly needed it.

"Dirty comics. So if I want to draw a naked girl, I have something to look at."

Now that he'd said the word, she'd remembered seeing the term before, spelled 'hentai,' on his computer, in his comic subfolder, some of the comics were labeled 'Hentai Collection,' like a subtitle. She thought at the time it was a company name. Now she realized it was something else, a word for a special type of porno. 'Hentai' and 'porno' even had complementary sounds in her head, so that kind of made sense. And Keith wanted to make his own, using pictures of her. That didn't seem so bad, as long as... "Promise nobody else sees? The pictures, I mean?"

"I'd get in almost as much trouble as you if they did."

She had to agree he had a point. And she already had some limited experience with risque photos, although nothing to this degree. Months ago she and a friend took photos of themselves in panties and tissue-stuffed bras and sent them to some boys their age in another city her friend knew through Instagram. They did it through Snapchat, and stopped when the boys broke their word and took a screenshot of one of the pics, but it was fun while it lasted, Susan's biggest experience with the thrill of doing something she knew was naughty, at least before today. And it really was flattering, that Keith wanted them in the first place, wanting any pictures of her was a compliment. Even if they were naked pictures... it's not like he hasn't already seen it all now. "Okay. How do you want me?"

He wanted her in many different ways, as it turned out. After he got his phone, it started simply, poses with her standing naked, turned in various directions, giving him hand-gestures or different looks. Then it moved to his bed, where she lounged in different positions, or on her hands and knees. It quickly became fun, not even a turn on, although she was still super horny, just a game, like playing supermodel, quality time spent with her brother that she found herself really enjoying. When he wasn't acting like a jerk, she loved this sort of thing, and even now, as a jerk, he was often complimentary when she struck a particularly hot pose. Sometimes he even said, "You're beautiful, Susan." A jerk wouldn't say something like that if it wasn't true, right? So Susan decided he must have genuinely thought she was beautiful. That was somehow almost as hard for Susan to believe as that she'd found a magic marker.

Sometimes he gave her an emotion to try for, and that was even more fun, like acting, he wanted her scared, happy... he got her to pose with her hands clasped together, just like she was when she was begging for his cum, and once with her hand over her open mouth like someone had just walked in on her while she was changing. He told her to try to look like what she did when she was cumming, a face she couldn't really remember, and then suggested she roll her eyes back in her head and let her tongue hang out of her mouth. That, when he showed her after, she didn't think looked very attractive at all, and made her self-conscious again.

Soon, the poses grew more explicit, one hand spreading her ass and pussy from behind, or laying on her back with her legs spread, and her hands pulling open her pussy, or a close up of her wet pussy. Soon, touching became more and more a part of the pictures, either her pulling her own nipples, or masturbating... not really masturbating, but doing a masturbating pose. That was a problem that got even worse when it wasn't just Susan doing the touching, when Keith took pictures with one of his own hands on her, or his own fingers in her. She wanted him to give her that orgasm she craved, but he'd just stick it in long enough to take a picture, and then move it. Similarly, he shoved a marker (this time, not the magic marker, but just a Sharpie) inside her pussy, then her ass, but not long enough to get any real fun out of it, it was all business, he just snapped a picture just as she was starting to enjoy it, and moved on. Soon, she was practically trembling with unfulfilled need.

That was when her brother started taking off his own clothes. Part of her was scared at that development, part of her was mentally screaming, "Yes, finally!"

The latter part was in charge of her pussy, but the scared part must have controlled her face and body language, because Keith said, "Don't worry, I just want to get some with my cock in the shot." He scooted up to her and told her to grab it. She did, and as soon as she had, with barely enough time for him to snap a picture, she popped it in her mouth. She was, after all, a cock sucker, thank to the magic marker. He took a picture of that, and pulled it out of her mouth, sort of slapped her with it, and then rubbed the slimy head along her cheek. He readied the phone to take another picture and... it wound up in her mouth again.

He pulled out again, lay it against her head, and again, she swerved her head and neck around until she could begin sucking it. "Goddamn it, Susan, stop sucking my cock, I'm trying to get a shot here."

"I can't help it," she said, although with her mouth full of cock, she didn't know if he understood the muffled words. It really did seem that whenever a cock got close to her mouth, she instinctively sucked it. He tried once more, pulling out and laying the swinging meat across her face, and she closed her eyes to slits, trying not to think about it, and she managed long enough for him to get one shot of it, looking like she was in some kind of rapture at having a cock nearby, when in actual fact she was just trying not to suck it. He pushed her back, hard enough that her head bounced a little off his bed before settling... at least now, his cock was far enough away that she didn't have that urge to suck it. Instead, she grabbed instinctively at her own crotch, running two fingers along her slit.

He stared down at her, then pulled her hand away, to her side, and leaned forward, his cock slapping against her belly. It felt warm... her pussy already felt like the warmest thing on her body, and yet his cock felt even warmer than that. She arched her back to raise her pelvis and get closer to it, even though she was already touching and she was in no position to get it inside her... to try to hint that he could do that if he wanted, go inside. All she could do was lift it, rub against it, but if he wanted, he could put it in, easily. The earlier thought about trying to get him to use a condom had long ago been forgotten and it didn't even cross her mind. He leaned back and took a picture, then another where the plum-shaped head rubbed up against the crack, bounced against the little nub at the top and sparked an electric jolt of pleasure that almost tripped her over into an orgasm right there and then. If it had bumped her a few times, she would have cum for sure, but instead he slipped back, down to the hole, where he wasn't inside, but it was like he was wearing her pussy hole like a penis hat, wrapped tightly around it.

"You know, what, what the fuck," he said. "I need to get some references for fucking, anyway."

"What?" she wanted it, but was stunned he'd just go ahead and do it, without even asking.

"Get ready to lose your cherry for real."

Chapter 12

She stared down at his penis, the one he'd just said he was going to fuck her with, already glistening and the head nearly all the way inside. That wasn't fucking yet, was it? So if she was going to stop it, this was her last chance to say something. "I'm your sister," was what she said, and she wasn't sure she even had a point to saying it, because she decided she didn't actually want him to stop, she just thought she should want that, and had to keep up appearances so he wouldn't realize he was giving her something she wanted.

"Relax, it'll be fun." Then he began swiveling his hips ever so slightly, and it started to go in deeper, and Susan decided she now knew why they called it 'screwing', because it seemed very much like a screw being slowly worked into a hole perfectly fitted, except instead of turning all in one direction, you went back and forth... but whatever the direction behind it, with every motion it went deeper.

That changed when he was about halfway in, after that it was more like a nail being pounded in, and she remembered they also called it 'being nailed', which felt even more appropriate than being screwed. After that, he took a few pictures, and then let the phone hand fall to his side and pushed into her, more slowly than a hammer blow, but with what felt like the same amount of force. Her pussy lips stretched to accommodate him, but it was a tight fit, tighter than fingers or the marker, it felt like she was almost being torn apart... but just holding it together, and with only minimal pain, pain which flared up when he went all the way inside her, like it was just grazing hitting a new barrier, a second cherry, but not penetrating. That first time he did that was an eye-opener... literally, her eyes bulged out in surprise that so much could disappear inside her, and that it could make her feel so... complete.

Soon he had a steady rhythm going, an in and out thrust, and each time there was the stretching sensation, the feeling of completeness, occasionally the slight pain, but she was growing to crave the completeness and the motion over any concerns over pain. Soon, she was pushing back against him with every thrust, and she made noises too, loud gasps, turning into moans, like each push was pushing air out of her body... she could try to shape it into a vocalization, or let it rush out of her like a loud breath, or even try to button it up entirely, keep it inside her until it built up and she had to let it out... but mostly, it felt most natural to make a noise. It wasn't the only noise, there was also the regular slapping of skin against skin, and her brother's own ragged breaths and occasional grunts, and occasionally it all came together cohesively, and it was like some kind of prehistoric first attempt at music, before people learned how to sing and dance. Maybe their motions were like the prehistoric first forms of dance.

But this wasn't dancing, it was fucking, she was being fucked, which absolutely, unequivocally made her not a virgin anymore, which saddened her, but it felt incredible, the waves of pleasure from motion alone, combined with the closeness, the completeness, the sheer sense of how naughty she was being, and he was being, and all conspired to bring her to the brink of another orgasm.

He raised his hand and snapped another picture, and she half-heartedly pushed his hand away, not wanting to be photographed like that, wanting to preserve some dignity... who had a photograph of their first time? With his free hand, he pushed her down, a hand around her neck like he was going to choke her, and then instead it slid down her shoulder and locked around her wrist. His phone hand encircled her other wrist, and, like that, pinned her to the bed as he continued fucking her.

She closed her eyes and turned her head away, mouth open, and tried to bring the orgasm on through sheer force of will, and whether it was that or just its normal time, it came. She just had enough presence of mind to realize that her tongue wasn't hanging out of her mouth, so Keith must have been exaggerating that part. Her eyes flitted open again after it was done, and saw him staring at her, and then he leaned forward, planting his lips on her own.

His mouth opened, and she felt his tongue against her, and it forced its way inside, or half-forced... her own mouth seemed to betray her and opened to admit it, and then his tongue invaded her space, probing as her own tongue retreated. It reminded her of those old fantasy movies where the hero was in a cave and a dinosaur or dragon was poking it's head in... it couldn't get all the way in, but that head would sweep back and forth, almost but not quite reaching those inside.

And yet, unlike the heroes trapped in the cave, a part of her wanted to be caught, and her tongue gradually moved forward, just enough to be pawed at, batted around, and convince her that she wanted more... and then it left, and his lips sloppily half-puckered on her face, leaving a trail of saliva.

He let her go then, and withdrew, pulling his back up vertically and taking another picture of himself inside her, this time all the way, and then he started thrusting like a madman, but she barely noticed, her mind still reeling, trying to figure out what the kiss meant. Seconds later, Keith groaned and fell on her, head falling to the bed beside her own, and she felt his cock begin to twitch and jerk, and what she knew was cum began flooding inside her.

When he was done, he pushed himself off her and stood, then backed away, got his phone, and took one more picture, of her legs spread and pussy open, lips slightly parted, now looking something like a flower blooming, but with some goo running out of the opened petals. "There we go," he said. "The perfect picture to cap off the collection." With that he turned away, like she meant nothing.

But she hadn't felt like it meant nothing at the time. "Keith..." she asked, and waited until he actually turned in her direction. "Why did you do that?"

"We both knew this was going to turn to fucking eventually," he said, and Susan realized she kind of agreed with that. "Hope you enjoyed your first time. Fuck, I know you enjoyed your first time, I felt it." He flashed her a grin.

But the sex wasn't foremost on her mind. Sure, it was a life-changing experience, but like he'd said, she kind of expected it on some level, the surprise was only in the details. And one detail in particular. "But why'd you kiss me?"

He froze for a second, and then shook his head with a sneer. "That's what you're hung up about?"

"That was my first kiss. That was supposed to be saved for somebody special." She knew it was stupid, but that seemed so much more important than taking her virginity.

"What, I'm not special?" He grinned. "And it wasn't your first kiss, when you were four, you were kissing everybody. You were a total kiss slut." It was true, and her parents would bring that up now and then, much to her embarrassment. Of course, they didn't say 'kiss slut,' that was totally rude and inappropriate, the sort of thing only a jerky older brother would say, but they'd tell the story and chuckle about it while Susan sulked... didn't people know that if something happened when you were too young to remember, it didn't count and should never ever be brought up?

"That was my first real kiss," she said. "The way adults do it." And it was with her brother. Not that she didn't like it, but it wasn't right, it certainly wasn't the kind of first kiss she could tell her friends about. "And you stole it."

"Don't you know anything about love?" Keith asked. "Stolen kisses are the best kind."

"Love?" she asked. She hadn't meant it in a weird way, she just repeated the word in pleased disbelief, happy for some signal that, underneath the jerk that she had created, he did, in fact, still love her.

But the way Keith reacted opened her mind to another possibility... for just a moment, he looked panicked, like he'd been found out, said something he shouldn't say, and then he put on that mask of casual amusement. "Don't flatter yourself, it's just an expression. I mean, I love you as a sister..." That made her mind race, not just an admission that, despite all that he'd done to her under the curse of the word 'jerk,' he did still love her... and also proving that that wasn't the kind of love he thought she might have thought, the one that caused the 'oh no, I've said too much' look. Now her heart was beating a mile a minute as a flush returned to her face. Could it be possible he had those kind of feelings? Even though he was her brother? And if he did, how did she feel about it?

She wasn't sure about that, but there was no sense in worrying about it if there was another explanation, so she gave him that chance. "But why did you kiss me then?"

"Because I thought it might be fun. That's all this is, Susan. Don't flatter yourself, twerp. There's nothing romantic going on, here, I'm just having fun playing with you. That's what I like most about you, lately... you're just a compliant little fuck toy, to use however I want."

"I'm not a... fuck toy." She hesitated over the swear, but got it out, only to realize with horror that she shouldn't have said anything, for her brother had that devious grin on his face.

"No? Well, let's see about that."

She saw him hop over a pile of clothes and make a reach for his drawing-desk, and Susan knew she only had seconds. It was either stay there and take another mark, become a 'fuck toy,' whatever that entailed, or run. She chose to run, sliding off the bed and landing on still unsteady legs, just as he turned around, the magic marker in his hand. She bolted out of the room, and heard him behind her, but didn't dare look back, not even really thinking. The last time she'd run, he caught her easily, but this time she had more of a head start, and he didn't seem to be giving it his all... maybe he was tired out from the fucking.

"You can run," he teased, "but we both know how this is going to end."

It was true, or mostly true, because Susan realized as soon as she reached the bottom of the stairs that there wasn't exactly anywhere to go... or, at least, any good options. She made a run for, and then skidded to a stop in front of, the front door.

She knew she could go outside, and could probably escape her brother that way. The problem was, she was completely naked, with nasty marker-writing all over her, and her brother's semen dripping out of her pussy (she could, she realized once she stopped, even feel it sliding down her thighs). The price of escape was exposure, both for her and her brother... she would have to face the humiliation of everybody seeing her naked, but, even worse than that, what had happened would get out, that her brother had written everything, had had sex with her. He'd go to jail, unless she could convince people about the magic, and even then, that might not be enough to save him. After all, it might not be his fault he's a jerk, but even jerks are expected to follow the law. And it would ruin his life, her life, the whole family's lives... mostly Keith's, though. She loved him too much for that, and she knew he loved her, too, even if she was wrong about it being more than family love.

By the time she'd turned away from the door, there he was, naked with the magic marker in his hands, looking... not angry, but annoyed. In that second, she'd realized she had another option... had, in the past tense, for there was no way she could make it past Keith now. If, instead of running for the door, she had run for the bathroom, she could have locked herself in and been safe from the marker. It wasn't a perfect solution, by any means. She'd have to hope he'd lose interest in it, or their parents got home, before she became too horny, or her sperm addiction became too intense... she now knew if she got like too bad she'd beg him to write on her just so that he'd satisfy her.

There was no escaping it, she had to face what she was about to become. She did give one half-hearted attempt to duck past him, but he grabbed her arm and dragged her towards the couch. "Please, Keith... don't write anything else... it's hard enough already..."

"You know, I wasn't really going to write it... I was just going to scare you," he said. "But then you ran, so I'm afraid I need to teach you a lesson." He fell, seated, into the couch, and dragged her into his lap. She could feel his dick bumping against her, hard once again, not fully, but clearly the chase had excited him. "Stop squirming, or I'll make you stupid, too." That did it. She just gave in, going limp. She might not be brilliant, but if she was going to find any way out of this, she couldn't afford to be stupid, too. Keith smiled at her sudden obedience. "There, see... you want this, don't you? You'd like to be my little fuck toy..."

How bad could it be? she wondered. Her eyes widened as he dropped the pen down to her chest, above her nipples, around the level of her breastbone. Which meant she'd have to wear clothes that covered it, nothing low-cut, even to the relatively modest level that was perfectly fine for a girl her age. Even a loose t-shirt might expose the writing if she bent over in front of somebody. She had clothes that would work, but the image that wouldn't leave her mind was having to wear a turtleneck for a week. She didn't want that... it was summer! Bad enough she couldn't wear short shorts. "But..." she said, weakly, hoping he wouldn't take it as a struggle.

"Shhh," he said, and it was too late already, he had already written the 'F'. The damage was done, especially when he completed the 'FUCK'. After that, she mentally sorted through her favorite outfits to try and find ones she could still wear. "There we go," he said, once he was done, and, to Susan's surprise, he gave her a sudden soft kiss on her forehead. The unexpected affection startled her, especially coming from a jerk, but she didn't know how to react, or how she was supposed to react. Instead, she focused on the bigger issue. She bent her chin as far as it could go, and read what was now written there. Yep, she was a fuck toy.
