I was delirious with pleasure. It was overwhelming. My hands reached down to grasp her head and I clung to her as though she were an anchor that kept my entire universe from spiraling out of control. Her mouth was hot and fast. Her tongue was agile. Her motions were deliberate. Her goal was clear. She worked fast and hard to bring me to climax. Any notion I might have had of resisting was bound and gagged by the power of the pleasure she gave me. I began to wonder if I was even awake. Perhaps this was all a beautiful dream.

It was not a dream. I realized this as I began to orgasm. The intensity of the gratification increased sharply all of the sudden and before I knew it my entire body was tensing up to deliver a long overdue ejaculation. It was then that the dark power inside me that had stopped me from having sex with Dana began to awaken again. There was a sudden, almost violent surge of negative energy inside me that wanted nothing else but for me to cease and desist immediately. My body cringed from it. My mind almost bent. It was too late however. Caroline's sweet and luscious little mouth had beaten it.

My semen blasted out into her mouth with an alarming force as the orgasm arrived. She coughed in surprise and struggled to swallow, but it was too much. The vigor of my ejaculation overwhelmed her normally adept little mouth and she had too pull away to stifle a gag. She coughed again and my semen began oozing out the sides of her mouth, and dribbling down my shaft. She quickly recovered however, and with a sweet little purr or excitement she resumed her motion and suction, determined to finish me off to the best of her ability. I cried out my inexplicable appreciation and tore the bed sheet from the mattress, feeling like I would spin right off the earth if I didn't hang onto something.

"Bah-mwau, ma mim," I babbled. I don't even remember what I was trying to say. Perhaps I wasn't even trying to say anything. The glorious pleasure was too much for my virginal mind to take.

As she worked the orgasm out of me I felt something else escaping as well. There was a great energy flowing out of my body, almost as if someone had pulled the stopper out of a sink. I felt it drain away as the orgasm worked its way through my system and wound down to a conclusion. All tension, anxiety, and frustration departed as well. A beautiful girl was sucking a load expertly and worshipfully from my cock. I felt like a king.

Her head swirled and bobbed as she sucked and swallowed, and her eyes flicked up to drink in the look of heavenly satisfaction she had painted all over my face like an artist. The orgasm was complete. The semen and all else had been drained from me. I lay there peacefully enjoying the gentle massaging of her mouth on my cock. I'd never felt so good in my life, and it had all happened so fast. One minute I was sound asleep, and the next minute I was laying there in the blissful afterglow of post-orgasmic serenity.

My erection weakened a little inside her hot and slippery little mouth and slowly began to wither. She decided I'd had enough. Her mouth popped off of me with a slurp of suction and she lovingly lapped up all the stray dibbles of semen that had fallen around the base of my cock. Finally she tugged up a section of the disheveled bed sheet to wipe the mess from her chin. She reached for a glass of water I had sitting on my nightstand, took a big gulp of it, and gave her mouth a good rinse. Then she sat back up again, adjusted her cute little thigh-high skirt, and looked down at me with a smirk of pride.

I just lay there staring at the ceiling for the longest time waiting for the room to stop spinning like a carnival ride.

"What the fuck was that all about?" I said eventually.

"I honestly have no idea," she confessed. "I got home a while ago and I came in here to see if you were home, and there you were laying there looking like some kind of fucking god of sexiness. It was insane! Something inside me just snapped. I wanted you so bad. I just couldn't resist it. You looked so amazing laying there. I just lost all control. I mean, you're my brother for god sake! I don't know what the hell came over me, but I just couldn't stop myself."

"I've seem to be getting that a lot lately."

"I mean, not only are you my brother, but I'm like, so totally in love with Stan. But you looked so irresistible there. My legs went weak. My mind went gooey. For a moment there was nothing that seemed more right in the universe than to give you pleasure. So I just slid your underwear down and fuck me sideways seven times if your cock was the most beautiful thing I'd ever seen in my whole life. I just had to suck it. I'm sorry."

She almost seemed to be talking to herself more than to me, as though she was trying to rationalize herself back into sanity.

"Don't worry about it, sis. It was nice. I mean, It was beyond nice. It was incredible!"

"It must have been," Caroline said. "You got hard in my mouth almost instantly and before I knew it you were popping off like a toy gun. God damn, that was a lot of come too. You must have been saving that for someone special. It only lasted about 45 seconds in all. Even at his most excited, Stan can usually last at least 3 minutes. I am pretty fucking talented though, I guess."

There was a tinge of humor in her tone, mixed with a bit of disappointment. Her goal had been to make me come though, and that had been accomplished. She tapped on my tummy with her fingertips in a gesture that revealed her feelings of inner triumph.

"I was asleep through a good part of it. It's a good thing. If I'd woken up I might have stopped you."

"I wouldn't have let you stop me. I would have raped you I think. That's how bad it was."

"Damn," I muttered.

Her fingers traced a line down from where she had tapped on my tummy, and she began absentmindedly stroking at the skin of my scrotum with her fingernails. It was sweet and ticklish. My cock began to stir once again. She looked down at it with a look of drunken lust glazed over her face. Her eyes gleamed with a fire that almost unnerved me. I began to feel like prey.

"Look at this thing," she said with animalistic appreciation. "It's huge! The last time I saw this thing it was a tiny little worm. You must have been like five or six years old at the time. I was hiding in your closet because I'd broken one of mom's lipsticks. I saw you masturbating on your little blue blankey. It was so funny. But now look at you. You're huge!"

"Thanks," I replied. I wasn't sure what she was talking about. I wasn't enormous or anything. My cock head was currently dripping precum into my belly button as she gently slid her fingers along its length. It throbbed beneath her touch and for a moment it's length and width expanded a little more, but that was about as long as it got. Besides that, her boyfriend Stan was larger than me. Perhaps her perception was skewed by lust. Perhaps my penis size was amplified in an illusion by the amulet, the same way my attractiveness had been. The crazy thing seemed to have many such tricks.

I paused at that thought. Something was wrong all of the sudden. The power that I had felt humming inside me for the past few days was suddenly silent. I reached up and touched it. It felt cool once again, even though it should have felt intensely hot with Caroline softly stroking my cock with her hand. There was the easy feeling of confidence I'd first felt when I'd touched it in the display case at the museum, and the illusionary attractiveness seemed to still be there, but all else was gone. I couldn't see into Caroline's thoughts, I couldn't project any lust into her. The power seemed to be drained from it.

Suddenly the full revelation of it hit me. The power of the amulet must be charged by my lust! It wasn't female arousal as I had thought. It wasn't proximity to sex. It was me. The amulet had been using me to increase its strength. Now that I was sated however, after the fantastic mouth work Caroline had administered, its power was diminished to almost once again. This would explain why it had not wanted me to participate in any of the sex I'd witnessed. This is why it worked to block me from fucking Dana. Caroline had tricked it though. She'd gotten to me while I was asleep, and before it had a chance to react I was already finished. Wow! It all made sense now.

There was only one problem. I no longer had all the powers of the amulet to work with. This must be the great sacrifice the priests of Eros had to bear. The amulet had been trying to tell me, but I had been interrupted by that Jennifer girl. The trade off was great sexual power, without participation. This must be how the sex god Eros protected the priests from exploiting people. This must be how he had planned to keep the religion pure.

"Do I still look sexy, Caroline?" I asked, breaking from my train of though. To what extent was the amulet's power diminished? She hadn't run out screaming or anything. That was a good sign.

"You look pretty damn hot to me," she purred, stroking my cock more purposefully. It was fully erect now, and she wanted it inside her. That was the next step to consummating our little encounter. Did I really want to fuck my sister though? I was a horny little bastard, and she was so damn sexy, with such a hot body, and the way she was moving was making me a little gooey in the head, but the idea of incest was still a little too weird for me. I would have done it perhaps any other day. I would have been less rational had I not been deliciously satiated by the expert blow job she had just given me. Besides that, my mind was now turned on to curiosity about the amulet. I wanted to discover its secrets more than I wanted to discover Caroline's at the moment.

I did not want to offend her though. Women were hypersensitive when it came to rejection. Even though she was my sister, and what she wanted to do was morally and legally wrong, her ego would still be bruised if I rejected her advances. Women are funny that way.

So I was caught between a rock and a hard place. On one hand, she was eagerly massaging my cock in a soft slippery grip of exciting female attention. On the other hand I wasn't feeling entirely right about having sex with her. She wanted to fuck me though. That was certain. She let go of my cock all of the sudden, and with a deft little tug, her panties disappeared into an inconsequential heap on the floor. She crawled up the bed over my body and positioned herself to mount me, assuming I wanted it too. Her pleated skirt flared out across her thighs as she moved downward, and a sweet little nest of slippery moisture suddenly descended onto the shaft of my cock. I flinched, shocked by the sudden intensity of it. She began sliding that wetness up and down the length of my shaft. I laid there helplessly enjoying the feel of it. She seemed to revel in the innocent bliss that her motions painted onto my face. I was shaking and trembling like a nervous little kid, but she was strong and confident.

"Much better than masturbation, isn't it?"

I nodded dumbly.

"Hold on to yourself. It gets much better."

I had no doubt about that, but even without the amulet interfering I still couldn't go through with it. Perhaps I might regret it later, but I had to stop her.

"Wait," I said. "Hold on. Not yet."

She balked. My cock was speared comfortably in between the heated crevice of her labia. She paused in her efforts to lubricate the length of my shaft with her excess juices. A pall of nervousness fell over her visage. She was suddenly worried that I perhaps didn't want her. The situation that should have been incredibly sexy was suddenly reduced to clumsy awkwardness. My cock throbbed involuntarily as though prompting me to shut up and get on with it.

"What?" she asked. "What's wrong?"

"What if mom and dad come home?" I suggested.

She smiled a little in relief, deciding it was just the nervousness of being caught that was bothering me.

"Don't worry," she said. "They're not due back until midnight, remember? They got that thing with the company? It's only 7:20 PM now. We've got plenty of-"

Her sentence was cut off. I had tried to shift myself out from underneath her and had succeeded only in dragging the end of my cock deliciously across her clitoris. She shuddered and ground down into me with a gratuitous little moan. My mind scrambled for another way to talk myself out of this awkward situation. She resumed her slippery little back and forth motion on the shaft of my cock. I shuddered and shook beneath her once again. My resolve was beginning to weaken. Would it be so bad if it just slipped in, just for a moment into her hot, tight, swirling little cunt? I was struggling to come up with a good reason why it would.

Fortunately the amulet began heating up a little due to my growing arousal, and it began to exert its negation once again. As it heated, its power began to grow and I began to feel the subtle tug of resistance to sexual gratification that I had felt earlier that day in full force. Could it muster up enough resistance to Caroline's sexy little dance of seduction though? The head of my cock slid across the opening of her sweet little cunt. With a deft little scoop of her pelvis I would be gathered up inside her and buried to the bottom. She reached down to guide me in.

"Wait, Caroline," I said again, stopping her conquest with a gentle push of my hand. "I don't feel right about this."

"Why not? You let me suck you off." There was a hint of impatience in her tone.

"Yeah. I know, and I'm grateful too, but now I'm just- Well I'm worried you'll come to your senses after we're done and feel bad about what happened. I really, really want to do this, but it might end up being too awkward. You know what I mean? You love Stan so much too. I don't want you to have any guilt interfering with that. It's beautiful what you two have. I don't want to ruin it."

Caroline stopped. The look on her face was visibly changed. The gleam of lust slowly faded from her eyes as my words sank into her heart. It's possible she still wanted to fuck right then, but the reminder of her love for Stan was like a bucket of cold water splashed into the face of her common sense.

"I think you're right," she smiled sadly. Then she climbed off me, wiped me dry with the edge of the sheet, and laid down next to me on the bed. She buried her face in my chest next to the amulet and sighed in frustration.

"Sorry, Sis'," I continued. "I know how these things go. It seems like a good idea at the time. You're all blinded by lust and ready for action, but once the ball drops at the end, it's a lot easier to see that the whole thing was a mistake. Then you just feel awful, and everything's weird between you for the rest of your lives."

"Yeah. I guess you're right. My head is agreeing with you, but the more I look at your cock, the more I want to just say fuck it! Let's rock!"

I sat up grabbed my underwear from the bed at my ankles and tugged them on.

"Better?" I asked.

"I guess so. Thanks," she said.

"No prob."

There was a moment of silence as we both calmed down from the excitement of what might have happened. Finally Caroline spoke again.

"I love you, ya know, Gil?" she said. "I give you a hard time, but you're such a great guy. You've got a good heart."

"Thanks," I said back.

"I'm proud of you. I'm glad to have such a great guy for a brother."

"You're pretty cool yourself, Sis'," I said.

"You know," she grinned. "I got a lot of hot looking girl friends who are always complaining they can't find a really nice guy. A nice guy with a delicious-looking cock like yours is a commodity in the circles I run with. You want me to hook you up or what?"

I thought about it for a moment. Some of her friends were very damn hot, but I couldn't picture any of them giving me the time of day. Not without the help of the amulet anyway. That notion burned in my guts a little.

"Girls don't want nice guys," I answered. "They want guys who will rock their world. Sexy guys. The hunks who will treat them like trash, use them for all they can get, and then move on to the next chick in line, and the chicks keep coming back for more because of the rush they feel when they're with them. Meanwhile, all the nice guys of the world are left dejected and all alone."

"Not all girls are like that," Caroline argued. "I mean, at least I'm not anyway."

"Well I can't exactly date you, can I? All I've ever gotten from any of your friends was grief and ridicule. Now that I'm no longer a loser or whatever, it just seems so shallow that they would suddenly be all over me just because you said it's okay."

"I think you're underestimating my friends. If you got grief for being a loser, it's probably because you were a loser to some degree. I wouldn't hang out with some bitch who treated you unfairly just to be mean."

I suppose she was right. I was probably talking specifically about Crystal more than anyone else. It wasn't fair to paint all women with the same brush. Caroline wouldn't have objected to my summary assessment of the fairer sex if there was some truth to it. I had to give her that. She was being honest with me. The truth was, I had been a loser. I was a nerdy little bookworm who seemed to look down on other people who were supposedly intellectually inferior to me. Now that I looked at myself from a different perspective, I couldn't imagine anybody liking a person like that. Now that I thought about it, my dismal social situation was mostly my own fault. Caroline was right. She didn't beat me up about it though. Instead she changed the subject.

"So what is this thing you're wearing? It's kinda cool looking."

"It's some sort of amulet I picked up from the museum a couple days ago, It's been causing me a bit of problems lately."

"How so?"

"I don't know if you'd believe me if I told you," I said.

"Try me."

"Well here's the thing. It seems this amulet is magic. It's got powers of some sort. It makes me sexier than I really am."

Caroline paused in thought for a moment and then said, "Actually I can believe that. That would explain why the hell I went nuts over you a while ago."

"Exactly!" I said. "It's like this weird power comes over me and all of the sudden I can control people's arousal. It even happens when I'm not even thinking about it sometimes. I can see things in a person's sexual past. I know everything they've ever done. What their hang ups are and what their turn-ons are. Everything."

"For example?"

"Well you for example. You're turned on by the sight of cock. Something about the visual of an erection in your face gets you so hot you can't control yourself. It started with Stan, when you and him used to fool around. You didn't want to go all the way at first, but you would suck him off whenever he wanted it. But then after a while just seeing his cock made hot. All he had to do is whip it out and you'd be on your knees pleasuring him with all your heart. Finally you went all the way with him and that clinched it. That's when he fell completely in love with you. You made him feel so adored, so awesome. He felt secure for the first time in his life. You gave him a gift no one else ever could. You convinced him to like himself because you adore him so much. He used to be jealous and possessive of his girlfriends, but now he has learned to trust you completely. You have convinced him of your love-"

"Stop," she interrupted. "You're making me cry."

Sure enough I felt a little tear cool my skin. She really did love him. I was glad I had stopped her.
