Keeping it in The Family Ch. 06

Roy was very excited, his sister Amy was becoming more and more of a slut as she got desperate for orgasms... although she occasionally crawled into his bed at night to suck him off, he didn't always return the favor. But then again, sometimes he did. He liked to keep her guessing, and she was very cooperative now whenever he started to play with her body because she was hoping that he would get her off. Her pussy was almost constantly wet and begging for attention; she was used to being able to get herself off, and she had masturbated almost once a day before. Now, with Roy refusing to let her play with herself, she had only him to turn to for relief.

She was almost ready to lose her virginity to him, and he knew just when he wanted to do it. Next weekend their parents were going away for his Aunt's 50th birthday party, leaving him and Amy all alone in the house. He'd have the whole weekend to fuck his sister, over and over and over again... his dick was getting hard just thinking about it. Knowing that his parents were downstairs watching a movie, he decided to go over and get Amy to do something about it.

To his shock, when he walked in, she jumped up with a guilty expression on her face and he realized that she had just been pulling her hand from her pussy. His own expression hardened and he gestured abruptly at the bed as he went over to see what she was looking at on the computer that was making her disobey him like that. Or maybe it was just because she hadn't had an orgasm in almost four days... it was the longest time that he'd made her go without. Still, she knew what the punishment was going to be, and he was going to relish spanking that pretty pussy.

When he saw what she was looking at on the computer, he started to think that maybe she would too. It was picture after picture of girls in bondage, being sexually tormented. His dick was aching in his pants now, as he looked at it.

"So you're interested in this?" he asked softly, scrolling down the page.

"No," said Amy, she sounded a little frightened, "I just found it... I was curious... It just popped up and I started to look at it."

"You were playing with yourself." He said, just as softly but there was condemnation in his voice.

Amy whimpered. When he looked over at her, she was curled up in a ball with both fear an anticipation in her eyes. He smiled, "Well, we'll experiment."

It didn't take very long for him to find some rope in his room, left over from Boy Scouts a million years ago. He tied her down to her own bed, stuffing her panties into her mouth for a gag. With her arms stretched above her head, her body was completely open to him, completely vulnerable, and he suddenly found out exactly what was so exciting about bondage. Smiling he stroked his finger down her body and she shuddered, his hand sliding back up to squeezed her breasts harshly, pinching her nipples and making her back arch. He could see her arms tugging on the ropes, but she couldn't do anything.

"Spread your legs," he told her, and watched as she did so, trembling. Her pussy lips parted with her legs, spreading wet pinkness. Two fingers pressed into her soft wetness and she moaned behind her panties, her hips lifting upwards as she rubbed her clit against his hand. For a moment he had the inclination to fuck her right then and there... but he really wanted to wait for that weekend. Do it right, not have to worry about their parents catching them. But he continued to press his fingers in and out of her pussy, watching as she writhed, her breasts jiggling on her chest, pushed out because her arms were tied above her head.

For her part, Amy was feeling more turned on than ever at her vulnerable position. She really had come across the bondage pictures by accident, but she'd found something very erotic about them... and she hadn't thought that Roy would ever catch her masturbating. Not that she'd been doing that exactly, she'd just been enjoying touching herself, not trying to get off really. But now, tied up like this, she found that it was even better in real life than on the computer screen. There was something very liberating about being tied up; she no longer had any control over the situation, there was no way to resist even though the guy between her legs was her brother... she was free to enjoy herself because no one would expect someone who was tied up to be able to stop what was happening to her. And so for the first time, her resistance and disgust completely crumbled, for the first time she knew that she wouldn't even feel guilty afterwards.

All tied up like this, the situation was out of her control.

Once she was very wet and clearly enjoying herself, Roy pulled his fingers from her pussy and slapped his hand against her open and exposed pinkness. Amy shrieked behind her panties and writhed, trying to close her legs as her poor pussy was slapped, but Roy was between them and he kept his left hand on her thigh, spreading it wide as he started to spank her pussy. Wet slaps filled the room as she wriggled in front of him, the pain seeming to go straight through to her inner being. When his hand hit her clit square on her hips jerked and she was shocked to feel the flash of pleasure go through her.

Roy seemed to realize that he'd hit a good spot and he started slapping her clit with every spank; now the sensations running through her pussy was a confusing mix of pain and pleasure. Her hips lifted, almost as though she was bringing her pussy up to meet the slaps, and Amy wasn't sure whether or not she wanted him to stop. With her wrists tugging on the ropes, her body writhing below, she moaned loudly as she started cumming, Roy stopped slapping her pussy and started rubbing her clit as she came, sending her on an intense and crashing orgasm.

He liked the fact that she'd cum while he spanked her pussy, and he was quite sure that the tender area was going to be quite sore after this. Her pussy lips were now a bright pink, and her poor little clit had to be smarting even if she was getting an orgasm out of it. It was so hot to watch her bound and gagged with her panties, and cumming on his hand after he'd just spanked her pussy. They were going to be doing lots of fun experimenting once his parents were gone for the weekend. The blood surged through his dick again, just as she started to relax out of her pleasure, her pussy still burning a little from its spanking.

Straddling her chest, Roy pulled the panties out of her mouth and shoved his dick in without untying her, he liked the fact that she was tied up in front of him while she gave him a blow job. Which she did with her usual gusto, a little afraid now that he had control of how far he pushed his dick in and how long he kept it there. Roy tended to hold his dick in her contracting throat longer than she was comfortable with, what she didn't know was that her throat started to ripple most pleasurably around him when she got anxious and he liked to hold it there to enjoy the sensation. Whenever he was in control she tended to be short of breath though, and she gasped whenever he pulled out and allowed her to get some air.

Rocking back and forth, Roy moaned as his dick slid all the way into his sister's mouth, her pretty lips pressed up against his groin. All he could think about was the next weekend, when he'd take her virginity and then fuck her all weekend long... maybe even tie her up to do it a couple times. They could christen every room in the house.

His dick got bigger and bigger in her mouth as she struggled not to gag, he was so excited that he was barely paying attention to whether or not she was taking him in her mouth easily. Amy struggled to keep up with his thrusts which were becoming stronger and harder, as though he was fucking her pussy instead of her mouth. When he pushed all the way in and began to cum, she gulped frantically to keep from choking as white froth shot straight down her throat.

A few spurts and Roy pulled out, spraying the rest across her face and hair.

Climbing off of her, Roy thought he saw a movement at the crack in the door. Crack in the door? Had he left the door cracked? He frowned as he realized that he could remember... but he didn't think that he would have. Still, he had been in a bit of a rush when he'd come in.

"What?" Amy's voice was soft and fearful as she strained to see what he was looking at.

"Nothing," Roy said, turning back and untying her, "Go wash yourself off." He slapped her ass as she passed and smiled as she jumped with a soft shriek.

Leaving her room, he looked up and down the hall but didn't see anything. Still, he didn't think that he'd imagined it. He wondered how much Dad had seen.
