Robert Vickers - Tied up with sis

This was the same rocking motion two people fucking used. It was an age-old rhythm. No wonder it was relaxing and exciting at the same time!

"Good Ron. Do it to me!"

"Yeah, Ron, do it to her. Let us see you fuck your own sister!"

"Don't pay attention to them. Just fuck me!"

His hips spasmodically jerked forward. The blonde girl had to gasp. Her brother's cock had been just inside her cunt lips. With that movement, he thrust his cock all the way up her cunt. She was in possession of his entire prick.

It felt like heaven after the things that had been done to her. She loved it, wanted more.

He seemed to read her mind. With a slow move, he started pulling out of her. She squeezed down with her cunt muscles to hold him inside. He groaned but continued. It felt like a giant fist squeezing him flat. Her young muscles were strong, pliable. The way his sister's pussy wrapped around his prick reminded him of fucking into a surgeon's glove.

The fit was perfect. He shoved hard back into her. The lewd smacking noise only spurred him to fuck her faster.

He used short strokes to build up the friction in her twat. His cock was already at the point of bursting at the seams. The blow job he'd almost gotten had primed his pump. He was ready to fuck.

That it was his sister's cunt was only a minor thing to his dazed mind now. All he really knew was that he'd found a tight, hot pussy willing to take his cock full length. He fucked harder, deeper.

Their crotches pound together. They moved together for a few seconds, then began rotating their hips in different directions.

He thought he'd lose his mind. It was as if his sister was intent on ripping his cock out by the roots. Her twat gripped fiercely at him. With the added movement, he knew he was going to lose control entirely at any instant.

"Hurry, hurry!" he whispered hotly into her ear. "I can't stand it much longer!"

The words were like a hot wind in the girl's ear. She was already at the breaking point. She was so aroused by her brother's fucking, the way he fucked his prick in and out of her clinging quim, that she didn't need much encouragement to cum.

As he really started humping her, their bodies began rocking heavily on the trampoline.

This added a brand-new dimension to their fucking. She tossed her legs high in the air every time they soared into the air. She felt his cock drive just a little deeper into her wanton cunt each time she did this. With the motion already in her twat, she was doomed by her sex.

She came.

As she thrashed about, this caused them to roll over and over on the trampoline. Par a brief moment, she was on top and he was fucking up into her twat. Then they were back in the original position, her brother weighing her down.

It didn't matter. As long as she had that hard, huge cock inside her guts, it didn't matter who was on top.

"Sis, your curd felt like a vise when you came. It crushed down on me from tip to balls!"

"It – it's okay, Ron. Really, darling, it's all right. Just keep fucking me! I need you so desperately!"

And she did. He was her entire world. Him and his cock. She felt that fleshy cylinder of prick shooting like a rocket up her cunt. The oils lubricating her pussy were burned away by the friction. The warmth slowly worked its way into her belly. It puddled there like liquid fire. Then it surged throughout her young body again.

She couldn't hold back this cum. It seized her in an ice-and-iron grip and shook her.

Blonde hair flying wildly, she tossed her head from side to side. She wished she could have gripped her brother's shoulders. It wasn't possible. Her hands were pinned under her, tied. Locking her slender legs around his waist helped a little.

She knew he wasn't going to get away. Not with that strip of adhesive tape binding them together. Yet, she wanted to make certain. The girl couldn't bear the thought of him leaving her. Leaving her with an empty twat that would drive her insane with unfulfilled lust.

"Fuck me harder! I love you so!" she gasped.

"Hear that? They love each other. Let's give 'em a real thrill."

The trampoline began bouncing faster and faster. It wasn't only their screwing that gave the motion to their bodies. The fabric was being bit by the two coaches to send them soaring into the air.

The girl no longer cared about anything. She had her brother close to her – as close as a man can be to a woman. He was digging into her guts with his cock. That counted. That was important.

The wild flying into the air seemed to add to their arousal. He managed to get in two or three strokes every time they were airborne. And she gripped even harder on his cock. She was almost constantly racked with the sweet torture of orgasm.

As they hit the rough fabric of the trampoline, she rocked back on her shoulders. This pulled her brother into her pussy as a slightly different angle. She could feel her pussy walls stroking his cock all along the underside. His plum-tipped prick grew larger in her. It throbbed with a new urgency.

Then he came.

She climaxed again when she felt his lava-hot cum burning all the way up into her belly. She knew her cunt was were convulsing, squeezing down powerfully on his entire buried length.

They flew into the air. The freedom that flight gave them added to the intensity of their mutual climax. When they smashed into the trampoline again, she came a final time.

Her entire body was racked with emotion. She was gasping for air. Her tits were throbbing with every hurried heartbeat. Most of all, the nearness of her brother, taped to her with adhesive tape, was the big turn-on. She had discovered how much she had wanted him sexually.

Melinda had a hard time admitting it to herself, but she found her brother incredibly sexy. She had lusted after him for quite a few years but had never admitted it to herself or anyone else before.

She had to tell him.

"Ron, Ron darling, I love you. I love you with all my heart and soul!"

She thrilled when he whispered back, "And I love you. It's hell that it took this to let us find out. But after this…"

"Yeah, what'll we do after this. The two of them have had their kicks. What about us, Sis."

The woman's voice brought the two incestuous lovers back to the reality of their predicament. They were still securely tied up and at the mercy of the two PE coaches.

"I don't know, Ellen. But seeing them bouncing around makes me think that might be a real fun thing to do. Are you game?"

He didn't have to ask twice.

Both of the coaches piled onto the trampoline, jostling each other and causing Ron and Melinda to worry about what new torture was in store for them. They doubted it would be as pleasant as the last few minutes had been.

With a loud tearing noise, Sid ripped off the adhesive tape holding Ron and Melinda together at the waist. The girl screamed in agony while the boy stoically endured the pain. He didn't want to give the man another method to always inflict pain.

"How do you want to do this, Ellen? You want the girl or can I have a turn at Goldilocks?" He licked his lips in obvious anticipation of having Melinda all to himself again.

"Hell, what would I do with a deflated cock? Look how limp the kid is after he fucked his sister."

Ellen reached down and lightly flicked the tip of the teenager's prick with her finger. It flopped loosely.

"Yeah, wouldn't be right. Besides, there's not a hell of a lot I'd want to do with him. So?"

Ellen bounced up and down on the trampoline and started them all soaring into the air. "I got it. How about a daisy chain? That'll give us all a bit of pleasure."

"So who cares about them?" he said.

"True, but we are teaching them a lesson. No reason why they shouldn't get it up close."
