Robert Vickers: Spouse swapping twins

She was on the brink of coming again. The pain of his initial thrust into her asshole had made her afraid he might rip and tear her delicate inner membrane. His slow entry had been pure torture for her until her resilient insides stretched enough to take the thick male invader up her back. When she felt his prick bucking and dancing around in her bowels, she did come.

He hung on and rode her for what seemed an eternity. And when she drifted down from her come, she felt his prick sliding out of her guts. She tried to stop it by tensing up. Her muscles clamped down on his hidden cock with impressive force.

Gasping, the man cried out, "I feel like I got my Goddamn cock stuck in a vise. A superheated vise, at that!"

She tensed up even more to persuade him to stay fully buried up her butt. His powerful hips pulled him out until only the knobby end of his prick remained in her body. But then he rushed back in. She screamed in pain. Her ass could barely take his cock again.

And out. He pulled out and created an intense suction in the blonde's bowels. She thought he would drag her guts out with his retreating prick. He immediately stuffed his cock back into her yielding body. She felt his hairy thighs rubbing against her ass. The way the man's balls wetly slapped against her cunt lips made her gasp in reaction. As he reached around and sought out her clit to fondle it a little, she came.

She came – hard.

Her body felt as if she had been dipped in acid. She burned. She cried out as she thrashed about. He kept his prick buried all the way up her ass while she was coming. His finger never left her clit. He managed to keep her sexually strung out longer than she had thought possible.

Mandy actually enjoyed the ravaged feelings in her body caused by the orgasm. She had come many times, but it had never seemed good to her before. Gone was all thought of showing Candy and Charlie that she was capable of giving them back their medicine. All that counted now was the hot and hard prick fucking her butt. She shoved her ass back to meet every single incoming stroke. She had to get it deeper into her guts. If it came out her mouth, that would be the best thing in the world. She could even suck the cock while it fucked her ass then!

"Can't hang on too much longer. Shit, babe, you're crushing me flat. And you're gonna burn me off. I don't want nothing left but a charred nubbin."

"Fuck and shut up! Greek me! Show me how to do it!"

Stan's fingers rubbed the woman's cunt. He had to hang onto her waist to balance himself. It was as if his hips had a mind of their own. He couldn't control the tempo of the fucking any longer. He began fucking with rough, ragged strokes. The power increased. He tried to rip her apart all the way to the chin.

He felt as if he had a pressure cooker dangling under his long cock. His balls had tightened up to the point where the jism was brought to a boil. He felt his balls lurching and tumbling around, and he knew that it wouldn't be more than a few seconds before he spewed out his creamy sperm and semen.

Her body tensed up around his cock again. It was as if he had sheathed his prick in a letterpress. He was being flattened. His cock pumped hard, and he fucked with all the speed he could. The friction mounted until he couldn't control himself any longer. Like a stick of dynamite, he exploded in the woman's guts.

"Aieeeee!" she screamed. "I – aaaaaeeeee!"

He continued pumping out spurt after gooey spurt of jism into her eagerly awaiting body until he went limp.

Panting, he dropped back and sat on his heels. Mandy maintained the position, her ass still jutting into the air. He stroked along it, then kissed her butt to show her how much he had gotten off on fucking it.

"God, Stan, I never dreamed it would be like that. Charlie is bothering me all the time to do all these filthy things, but…"

"But that didn't seem so dirty. Maybe it seemed like fun to you. Was that it? You wonder why you're not feeling guilty about it?"

"Something like that," Mandy turned and saw that her sister and her husband had finished off. Candy was gently licking off the come from Charlie's dead prick. But Mandy knew from past experience that Charlie wouldn't be flaccid for long. He would come back, harder and hornier than ever.

She shivered. That didn't seem like such a bad thing to her now. She had wanted to show him that she could attract another man Stan had obliged. But Mandy realized how much she loved her husband then. She just couldn't keep up with him in the sack.

She loved him but not that much. No woman could. No woman except Candy.

Mandy wanted to cry. The problems this husband-swapping had caused far exceeded the problems it had solved.

All of them sat around in a tight little circle. Mandy felt a bit out of place being half naked, but Candy was, stripped bare-ass naked and didn't seem to mind, and the men all had their limp pricks hanging out. Mandy tried valiantly not to show her discomfort.

"So figured we might as well try the swapping around and see how it worked, but you guys were too smart for us," Candy was saying.

"Too smart?" snorted Charlie. "It was obvious from the start. But I'm glad you did. You're hell on wheels in bed, Candy. Mandy just can't hold a candle to you."

"So you want to swap permanently?" asked Candy.

Charlie didn't answer immediately. He seemed to be thinking. He looked from one twin to the other and finally said, "No. I mean, damn, this is hard!"

"Not yet!" teased Candy, her fingers stroking along his prick. He slapped her hand and continued.

"What I meant was, I love Mandy. Hell, I married her. But she's not that sexed up, not like you. But there's more to marriage than just fucking."

"You mean you don't want Candy? You still want me?" asked Mandy. She was so confused with the things she felt that she didn't know what was right any more. The ideas in her head were so strange they frightened her.

"That's exactly right. If you had Candy's sex drive, you'd be perfect. But I won't trade you for her screwing."

"I like that!" flared Candy.

"Hang on, doll," said Stan. "I know what he means. Mandy and I are better in bed together than you and I ever were. We run at different speeds. It's like I'm thirty-three and a third and you're all the time at seventy-eight. But I don't want to give you up for Mandy."

"Isn't one hole the same as another for a record player?" Candy asked. "Isn't the size of the hole immaterial to the spindle?"

"There are other things to be considered, kiddo," said Charlie.

"Uh, everybody, can I say something?" asked Mandy. She was unsure of herself. She had always been the shy one, the sexually repressed twin. She knew that all twins developed this way. One was outgoing while the other was introverted. She just had the misfortune to be the quiet one. And this idea frightened her.

"Go on. If it's what I'm thinking, it'll be a dandy," said Candy.

"Why does anything have to be on a permanent basis? We're all hung up on this one-wife one-husband idea. Why not a… a four-way marriage?"

"What do you mean?" snapped Charlie.

"Look, all of us get along together well. When it comes to things not having to do with fucking," said Mandy, proud of herself for being able to say the word without stammering, "I'll do them for you. And when you get horny, you and Candy can get it on. I'll still want some of your time, of course," she said primly. "After all, you are my husband."

"And you and Stan will fuck?" asked Candy. "Yeah, I like the idea. Your pacing together is fine. We lead our regular lives up to the point of going to bed, then we switch off now and again. Is that what you mean, Mandy?"

"I guess so. This is all so strange to me. I've never even thought of being unfaithful to Charlie and now I'm engineering a permanent adultery."
