Chapter Three
That night, Sarah once again slipped into Seth's room.
"What's in the bag?" Seth asked.
"Ropes," Sarah replied evenly.
"Ropes? What for?" Seth inquired curiously.
"To tie me down to the bed," Sarah answered matter-of-factly.
"Whoa! Why do I need to tie you down to the bed?" Seth asked incredulously. "I'll just sit up and watch you, and that way we'll know."
"No, you shouldn't stay up," Sarah reasoned. "If you stay up half the night, you'll be dead in school tomorrow. Plus, what if you fall asleep? Just tie me down, then we'll know that I didn't get up."
"Do you really expect me to sleep in the bed with a girl that is tied down?" Seth asked.
"Don't be silly," Sarah exclaimed, throwing the bag to her twin. She lay down on the bed and raised her hands above her head. "Now tie me down!"
Seth sighed, but did as she ordered. He took one of her wrists in his hand and wrapped it around three times, being careful to leave a fingerbreadth of space underneath it, then pulled the rope under, tying a square know on top. He took another piece and did the same to her other wrist.
"You've done this before, haven't you?" she asked with a smirk.
"Shut up!" he exclaimed. "I just like ropes and knots."
"Mmmmm," was her reply.
He sung each of the ropes around the bars in the headboard and tied them off, stretching her harms well above her head
"Good enough?" he asked.
Sarah tugged at the ropes, unable to get out. "Now my legs," she demanded.
"I think that if you manage to get out of the ropes around your wrists, we'll at least be able to tell," Seth observed thoughtfully.
"Are you sure?" Sarah queried, looking slightly disappointed.
"I'm sure," Seth answered. "Though if you want me to tie you down just because you like being tied down, I'd be happy to."
Sarah blushed and stammered quietly, "N-no, it's not necessary." While it wasn't necessary, and she wouldn't admit it even to her twin, the thought of being tied down was not an unpleasant one. She sort of wanted to demand that her feet be tied as well, but she didn't want to push it, at least not the first time. Plus, she now realized that if her legs were spread like that, Seth would be able to clearly see the rapidly forming wet spot on her panties.
Having finished, Seth looked her over. She was lying on top of the covers, her hands extended over her head, in a posture which pushed her chest out. He noticed her erect nipples through her shirt. Her wiggling had caused her tee shirt to ride up a little, exposing her blue panties.
"You know," Seth said thoughtfully, "you are completely at my mercy. I can do anything I want to you."
"No you can't!" Sarah exclaimed.
"Sure I can," Seth replied. "Watch!"
He walked up to her, and she squirmed trying to get away. He reached around her sides and started tickling her.
"No, stop! Please! Stop!" Sarah shrieked in a stage whisper, trying not to alert their parents.
"See?" Seth asked, ceasing his attack.
"OK, you can do anything, but don't!" Sarah pleaded. After making the request, however, Sarah wasn't sure if she should have. The tickling was annoying, but the thought of not being able to do anything about it? That was far from annoying.
"If my friends knew that I was in this situation, with a beautiful, sexy girl tied helpless in my bed, unable to stop any advances, and I didn't take advantage of it... Sheesh!"
Seth sat down near the bed, and glanced boldly between Sarah's legs. Her shirt had ridden up more during their little tussle, completely exposing her panties. He could see a couple of wisps of brown hair peaking out of the edges, and a slightly darker blue spot in the middle. Sarah saw where he was looking and she gazed down, realizing that she was exposed.
"Please fix my shirt?" she asked her brother, realizing that her fear of exposure was in fact being realized.
"OK," Seth said, walking over to her again. "Lift up your ass."
Sarah did as requested, but instead of pulling down her shirt, Seth pushed it up to bunch under her breasts, exposing her panties and her flat stomach.
"Hey, I meant pull it down!" Sarah complained.
"If I have to be here with you tied to my bed, I'm going to take some enjoyment out of it!" Seth teased. He dimmed the light down to just a soft glow and said, "Now go to sleep!"
"Aren't you coming?" she asked.
"It'll take more than a glimpse of panties, though not much more," Seth muttered to himself.
"What?" Sarah asked.
"Sorry, just talking to myself," Seth explained, sitting in a chair by the side of the bed. "I'm just going to sit up for a while to see if anything happens soon. If it gets too late, I'll come to bed."
"OK," she replied, lapsing into silence. She squirmed around a little more, trying to avoid looking at her brother, and about 20 minutes later she was asleep.
Seth looked over at his twin sister's sleeping body, taking stock. The real reason that he didn't get into bed with her was because she excited him too much, particularly tied up this way. She was quite beautiful, and looked completely innocent lying there asleep. Her breasts were full and perky, and they pushed her shirt up. Her stomach was flat and toned, the result of her athletic bent. Her legs had separated slightly in her sleep, and he couldn't help but look between them. He shook his head to purge his thoughts, telling himself that this was his sister!
Seth stood up and changed into his sleeping shorts, but one look down made him realize that they were not appropriate, considering the obscene distance his shorts were tenting out. One last glance at his sister, and he made his way to the bathroom to relieve himself. He did his darndest not to think of his sister while he was whacking off, but images of the bound angelic teenager kept popping obsessively into his head.
As he sat back into the chair next to the bed, with his shorts now correctly fitted and his brain somewhat calmer, he picked up a book and read until he saw that it was about 11:30, the time that his mother usually went to bed. Seth had been peering over at Sarah quite often, trying to discern what was going on in her head. Was she dreaming? Was her mind in their mother's head?
Seth got up and sneaked out the room, peeking into the family room where his mother was watching TV. She seemed to be watching some soft-core detective movie, typical Skin-e-max. He shook his head, surprised that his mother would be watching the kind of fare usually favored by boys his own age and horny middle-aged men - well actually, horny men of all ages - and he returned to his bedroom and picked up his book again.
A few minutes later, he glanced over at Sarah again as she groaned quietly. He put his book down as he realized that her breathing had increased and her eyes were moving rapidly under her eyelids. As her breathing quickened even further, her hips started wriggling, and he noticed that her nipples were hard points under her shirt.
Seth sat back, and he could swear that Sarah was getting sexually excited. A quick gander between her legs and he noticed a growing patch of her panties that was darker than the rest. She was getting wet! She must be having one hell of a dream.
He watched as she slowly worked her way up for another ten minutes, then she gasped and arched her back. When she collapsed down on the bed, her panties were far wetter. Her breathing gradually slowed and she calmed down. Seth debated whether he should wake her, but he decided to keep watching. About fifteen minutes later she stirred again, and her eyes fluttered open.
"Did I get up?" she asked.
"Um, no. You didn't get up," Seth told her. "What happened, did you 'dream' with Mom again?"
She nodded.
"Tell me what happened!" Seth demanded.
Sarah glanced down at herself, debating whether she should ask or not, but finally, regretfully, she said, "Untie me first."
Seth did as requested, somewhat disappointedly, and Sarah sat up against the headboard, rubbing her wrists. "Next time we'll need to find something softer than this rope," she observed.
"Next time?" Seth asked with an arched eyebrow.
Sarah slapped at him playfully, and Seth said, "Tell me."
"Well, Mom watched the Daily Show for a while, then switched over to a movie, some sort of detective story that had already started," Sarah began.
Seth's mouth dropped open, and Sarah noticed. "What?" she asked.
"I snuck downstairs earlier as you slept, and I saw that Mom was watching one of those movies!" he said. "Damn, you really can do it!"
"Oh my god!" Sarah gasped. She hadn't been sure if she was going crazy, and this proved that she wasn't certifiable.
"What happened after that?" Seth prompted.
Sarah blushed. She ducked her head down so that she wouldn't be looking Seth in the eye and muttered, "She masturbated."
"What?" Seth asked in surprise.
Sarah looked up and said, "She stuck her hand down her pants and she masturbated. She was thinking about the guy on TV, and how he would do her, and she rubbed herself till she came."
"Oh lord!" Seth exclaimed. "And we have it on tape."
"I forgot about that," Sarah groaned. "You can't watch that!"
"You did," Seth pointed out.
"Still!" Sarah shot back.
"OK, you can watch it tomorrow and tell me if it happened the way that you experienced it," Seth agreed. He paused for a moment, and then said, "You know, Mom wasn't the only one that came."
"What do you mean?" Sarah asked.
Seth nodded towards Sarah's crotch. She looked down and realized that her panties were soaked. "You watched me cum?" she asked sheepishly.
Seth nodded.
"I guess that excited you," she said, looking at his crotch. Regardless of the relief that he had given himself before, his shorts were once again tented.
He covered his crotch with his hands and muttered, "Sorry."
"It's only fair," Sarah responded. "I can't say that I blame you." In fact, Sarah wished that he hadn't covered up; she was enjoying the view.
Sarah paused. "Now what do I do?"
"About what?" Seth inquired.
"About the fact that I can get into people's minds!" Sarah said.
"Well, into Mom's mind, at least," Seth corrected.
"Fine, Mr. Science Guy! What should I do about the fact that I can get into Mom's mind?"
"Why don't we just take it one day at a time," Seth suggested. "Go to Jill's tomorrow and see if the same thing happens, or if it's only Mom. If it happens with someone else too, then we should start experimenting some more to see what else you can do."
"Do you think I'm a freak?" Sarah asked nervously.
"Of course I do!" Seth answered. "But you're my freak!"
"Stop it!" Sarah said seriously. "I mean when people find out, I'll probably end up like a lab rat!"
"People can't find out!" Seth exclaimed urgently with a lowered voice. "Don't tell anyone else, OK?"
"OK!" Sarah said.
They sat quietly for a minute, both lost in their own thoughts, then Sarah said, "Let's go to sleep."
"You're going to stay here again tonight?" Seth asked.
"Please," Sarah wheedled. "I don't want to be alone."
"But," Seth said, looking at his crotch.
"Go to the bathroom and take care of that, then come back and hold me!" Sarah ordered.
"By myself?" Seth asked in an indignant tone.
"Seth, you get your ass into that bathroom and jack off, by yourself, then come back to bed!" Sarah replied firmly.
It was embarrassing that his sister knew he was going to jerk off, but Seth had just seen her cum, so it was probably fair. Minutes later, he was back.
"That was fast," Sarah observed.
"It didn't take much," Seth confided.
"Why is that?" Sarah teased.
"It's not every day that I see a beautiful girl cum in front of me!" Seth explained passionately.
Sarah held her hands open, and he climbed into bed. She snuggled up into his arms and whispered, "I'm scared."
"I'm here for you," Seth said.
"Thanks," Sarah said, kissing his cheek. Soon they were both snoring.
