Robert Vickers - Fit to be tied

She didn't intend the act to be sexy, but it was. With that long, nylon clad leg swinging free, the man was treated to a momentary glimpse all the way up to her crotch.

He looked up at her with wide eyes. "Sis, I don't want you to laugh at me. Promise me you won't." He licked his lips as he continued to study her legs.

"I won't laugh, Jack. That's the last thing in the world an older sister should do." She guessed right. He was younger than his sister. The way the man's face lit up told the girl everything she had to know to keep on with the play-acting.

"I-I don't have much experience with girls, Sis. And you're so beautiful. I… I've peeked at you some nights. While you were undressing. I saw you totally naked the other night."

She could see the bulge in the man's pants growing. He was getting a hard on talking about this. She decided to help him along. The girl dropped to the floor beside him and took his hand in hers.

"That's okay, Jack. You're male and I'm female. There's nothing wrong with you looking. In fact, I'm flattered you think I'm so pretty."

He blushed. Then, he said, "I… I want to do more than just look. W-would you show me what it's like? Between a man and a woman when they're making love?"

"You want to fuck me, Jack?" she said softly.

He nodded his head.

"All right. Do you want me to show you all the things a sister, an older sister, knows and her younger brother wants to know?" She didn't wait for an answer. The way his cock jerked hard in the prison of his trousers told her the complete story. He wanted her to lead him through the lovemaking.

He wanted his older sister to fuck him.

"It's not too difficult. Not too hard making love, that is. Now this should be hard." She unzipped his pants and let his prick snap out like the opening of a switchblade knife. A quick grab and she had her warm hand circling around his prick. She stroked up and down a few times to get his blood racing.

It worked. He almost creamed in her hand.

"Just lie back and let me do whatever I can to show you how it can be. Is that what you want?"

"Oh, yes! Yes, Sis, you don't know the years I've wanted you. Really wanted your body. To feel your cunt slipping down around my cock. To feel, ummm, oh!"

Her hand had begun to race up and down his pole until he had to gulp hard to prevent shooting off his wad. Satisfied he was well taken care of for a few minutes, the girl stood. He was able to look up under her skirt.

She wiggled a little and slipped her hands under the band of her pantyhose. She started pushing them down over her legs. Shaking hands reached up to help her. The fevered fingers she felt on her calf amused her. But she didn't laugh. This was for real to the man.

He helped her out of the damnable pantyhose, then she shucked off her panties in one smooth motion. Lying on his back as he could see all the way up to her now naked snatch. She bent her legs and began to sink down beside him.

As she was slowly lowering her body to the rough hewn floor of the mock tree house, she took one of his hands and slipped it to the inside of her leg. There, she pushed it gently toward her snatch.

"Go on. Explore around and tell me everything you find there."

"A-are you bleeding? It's wet!" he exclaimed.

She laughed. "No, it's all right. I'm just getting ready for you. I have to get all hot and excited and juiced up before you stick this in. And you're making me get damp. You."

She gasped when his fingers found her cunt and dived far up her. The way the man worked his fingers around in her pussy told her he was no virgin. No man could find all the right nerves to stimulate without having done this before.

The girl realized then that the playacting was only a role. The actual fucking would be for real. And she'd be getting her tight little quim filled to overflowing with long, hard cock. She squeezed down on his prick again and decided this wasn't such a bad deal.

The man was hung like a bull. His cock was long and stiff and would be a real pussy pleaser.

"Go on," she moaned softly. "Feel me all you want. There! That's my clit you're fingering now. I feel lightning blasting into my guts. You're doing it to me. My own brother is giving me more pleasure than any other man ever has."

"Are you ready for my cock yet?" he prompted.

"Yes, yes! I can't stand it any longer. I need that prick of yours deep up my cunt fucking the hell out of me."

"Show me how, Sis! Show me the way to do it!"

She gripped his prick and held it straight up from his groin. Then, straddling his waist, she spread her pussy lips wide and simply sat down. The cock touched lightly on her sex lips for a moment.

The carnal shock that rattled her teeth was immense. She simply hadn't realized how much she was getting into this little fantasy. She wanted to be this man's sister. She wanted to be showing him the delights of sex for the very first time.

She wanted it all to be true!

"I can't see what's happening," he complained.

She ripped her skirt off to fully expose their genitals to his questing gaze. He could see her pink inner pussy lips spreading out to lewdly kiss his cock. And they both knew the instant she relaxed a little and let her body sink down around his prick.

The man's cock buried itself hard into her soft cunt. The juices she'd been leaking out helped a little. But the man's prick was dry. It hadn't made the trip up her juicy twat yet.

Inside her love tunnel, the prick jerked and lurched hard against her velvety pussy walls. She clamped down a little with her stomach muscles and felt the outline of his prick.

The broad head flared out to press firmly into her cunt. And the loose skin of his cock was quickly erased as if by magic. The excited blood pounded hard into his cock and stiffened it even harder. The big blue vein on the top of his cock pulsed wildly.

She knew this was going to be a hell of a good fuck. He wasn't a beginner at this, no matter how he protested.

"Sis, my darling sister! How long I've wanted to feel you all around me like this!"

"And, Brother dear, the feel of your cock in my cunt is more heavenly than I'd have imagined. But this is incest. We're brother and sister. This is a sin!"

The man's cock jerked inside her. She knew he was reacting to the fantasy now. And she was determined to give him the full measure of her acting abilities.

"But I don't care! So what if we're brother and sister? I love you! I want your cock fucking me more than anything else in the world! So, fuck me, damn you, really fuck me!"

She was taken by surprise. She didn't count on his reaction being so powerful. She felt herself being lifted up by strong hips and tossed into the air. Riding with it was easy. She managed to hesitate at the top of her arc long enough to gather her wits.

Just the purpled acorn-like knob of his cock was left in between her pussy lips. She paused there for a moment to let the cunt juices fully wash over his prick. Then she simply relaxed. Gravity did all the work for her.

Body hurtling down on the well-greased spike of his cock, she felt his prick smashing into her cunt. It took her breath away. And once at the bottom of her fall, she began grinding her hips back and forth. She tried her damndest to get his cock an extra half inch up her twat.

The rotary motion of grinding her bush into his produced the most ecstatic feelings in her body she could imagine. The skin was stretched and pulled taut over her clit. That pea-sized little organ of pleasure was throbbing with sex now. And as she worked his cock even deeper up into her belly, the little go-button seemed to explode.

She felt the sexual tension suddenly snap in her body. Then the loose ends of her emotions smashed all around her. She came.

"Oh, dear Brother, you've made me cooommme! Cooommme!"
