Robert Vickers - Tied up with sis

She came suddenly. There wasn't the usual buildup like there had been in the past. She just came and felt the equally sudden post-coital fuzziness come over her.

The threefold stimulation was too intense for her to really appreciate all that was happening. The girl tired to sort it all out in her mind.

It was hard to do.

The cock fucking her up the cunt was Sid's. She didn't have any trouble keeping him straight from the others. It was his hands on her tits, fondling, kneading the flesh, trying to remold them into new shapes.

The way he worked lacked finesse. He was just flat out fucking her as hard and fast as he could. And she didn't mind that at all.

The feeling of his cock racing up her well-greased cunt was enough to fill her with tiny flames of passion. The continual stroking in and out of her twat made those flames bum a little brighter. When he reached the paint of really fucking her, the flames exploded into a fire that consumed her entire soul.

She could handle that.

It, of all the bizarre sex she'd had that night, was the most normal – or what she considered normal.

It didn't much matter that he was the one who'd tied her hands behind her back and kept her helpless all this time. In its way, the girl thought this was sort of sexy.

She didn't mind being held captive by him – most of the time. It got her hot fast and made her cums seem longer and longer each time.

It had to be one of the other two points of stimulation that had brought her to her climax so damned fast. She tried to keep all the feelings straight. She could feel how Sid was fondling her tits, stroking the undersides and then tweaking hard on her ripples. And his cock she felt every time he drove hard into her cunt.

She had to concentrate to keep it separate from her brother's prick reaming out her ass. She'd never had a man up her ass before. When he'd popped her cherry, she thought she'd have at least one hole left untouched.

That just showed how little she knew of the two teachers.

They were sex fiends and got their kicks in a variety of ways.

Seeing her humiliated was just one of those methods.

She had to admit having her brother fucking her had been a high point in her young life. She'd loved it. In spite of the circumstances, the feel of his prick fucking her had been wonderful.

Her only regret was that the time together had been too short. She'd have preferred something a bit longer – like all night!

But that wasn't in the cards. And now they were forcing him to buttfuck her. She felt his cock fucking her delicate anus and digging hard up her rectum. The pain she felt washed over her. It covered her totally with agony. Now and again she was sure he would tear her apart and she'd die a messy, bloody death.

It didn't happen.

Her young asshole stretched just enough to accommodate his huge prick. When she got the hang of it, the dual fucking wasn't too bad. Sid would ram home up her juicy cunt, then begin to pull out. As he did, her brother rushed up her tailpipe, filling her guts with his cock. The pair maintained at least one prick inside her belly at all times.

The friction between her brother's prick and her asshole made her think add had been dripping into her.

She finally got the proper rhythm. Shooting her hips forward allowed her to take Sid full length up her quim. As his cock pulled out, she could ram her hips backwards.

Her brother's prick surged up her rectum. She wiggled her ass a little and felt his hairy thighs rubbing against the smooth skin of her rear. That alone was sexy but the feel of him inside her, twitching and jerking in lust, was enough to bring her to climax again.

"Aaaiieee! Oh, Christ, it's toooo goood!"

She let her body wiggle and shake and writhe out of control. The two cocks ended up inside her at the same time. She twisted and stirred them around in her guts until the sexual tensions built to the breaking point again.

She came again. And again and again.

None of her orgasms was prolonged. They were all sharp, fast. She felt them like ice picks digging into her brain. A cold, thin blade stabbing at her senses, then exhaustion.

"Stop it, I… I can't take too much more!" she begged. "I'm worn out. Please!"

"So Goldilocks has had it! Well, I haven't. Keep fucking, kid. We'll show her what a pair of men can really do!"

The girl was dimly aware of their cocks sliding back and forth in her body. One up her cunt, the other out of her ass.

But it was the more elusive, the more gentle, sensation at her twat which held her attention.

Ellen was still at work, lapping and licking all around both cocks as they fucked hard into the girl's body.

That tongue was driving the girl mad. She had to cum; her body wouldn't let her. It was tired, completely sated. But as exhausted as she was, she felt the tremblings of a new cum building up inside her.

"I like the taste down here. I'm getting the best of both worlds," Ellen called out.

The girl was limp. The water prickling her skin with its warmth did nothing to revive her now. Only that tongue, pressing, probing, touching her here and there, kept her from passing out.

As Sid rammed his cock into her pussy lips spread wide apart. The woman's tongue pressed those sex lips against his cock. Trapped and unable to go anywhere, the girl's labia received the full benefit of those oral attentions.

As the cock pulled free, the woman licked off all the cunt juice. Not a drop of the salty, tasty thick oil escaped. Once, a tiny river had begun down the inside of the girl's thigh, then a rough tongue scooped it all up.

The perineum was fair game for a tonguing. The sensitive skin rippled in delight, even if it didn't fully penetrate to the tired girl's brain. Her body was screaming a song of joy.

As her brother's cock fucked inward, the probing tongue was there to give it a nice treat. The underside was given a full, heartfelt tongue lashing. The cock seemed to stiffen even more inside her after that light touch.

But the girl shivered from the tongue pressing upwards between her meaty asscheeks.

That was all that kept her going. Otherwise, she would have said, "To hell with it," and let the two do what they would to her.

The teenaged girl heard her brother's sharp gasp. He was sucking in his breath and holding it. Up her ass, she felt his cock begin to grow in size. This was it.

He screamed a loud, heart-rending shout, then jammed himself a bit farther up her behind. He came, his jism flowing sluggishly at first after being restrained and denied so long. Then it geysered into her.

She felt her bowels getting the sexiest enema ever. His cum was burning hot as it fountained inside her. She crammed her hips back and began wiggling her ass in small circle. She wanted him to get the biggest sexual high possible from this.

The girl realized how badly tortured he'd been. To be pulled to the edge of cumming, then shoved away time and again had to be the worst sexual torture imaginable.

Almost as bad as being sexually satiated – and still having cocks jammed into every available orifice.

"It's damned good," he said. "I… wasn't able to hang on any longer. Forgive me, Melinda. Please forgive me."

"N-nothing to forgive, Ron. Th-they're making us do this. It's them who should, ummm, oh. OH!!"

Another sharp spike of pleasure lanced through her. Sid was cumming. The sudden release of his pent-up jism took her by surprise. But the first touch of his manseed in her quim was all it took to set her off.

She regained her voice rapidly. "I can't take any more. I'm about ready to pass out."

To emphasize her point, she let her legs relax. She fell in a golden-haired heap under the shower. The water caressing her skin felt good. And having a vacant cunt and asshole felt good, too.
