Margaret's Little Experiment

"I'm massaging his prostate," said Lucy. She'd never done this before but had watched a video about it somewhere on the Internet and read about it too. It was something she'd wanted to try with her husband but he was adamant that his arsehole was strictly out of bounds. "Now, make love to her bottom," said Lucy, with emphasis on the word 'love. "Go slowly and steadily, or I won't be able to keep up."

With some skill, Lucy kept pace with the slow deep thrusts with which Brian now buggered Margaret. His hips rocked steadily back and forth, and Lucy was able to move her hand in time with them, giving his swollen spunk node a hard press when he was at the end of his stroke with the tip of his penis at its point of maximum insertion inside Margaret's body.

Margaret had never experienced anything like it. Actually, now that the initial pain of penetration had subsided and her bum had accommodated his penis, Margaret now wished he'd fuck her harder. In fact, she threw him a bit by starting to masturbate her clitoris with a vigor that far exceeded his pensive fucking of her bottom. He had gone from hurting her too much to not hurting her at all, and she wanted something in between.

Whatever the case, Lucy could see that this was going to lead to them both having extremely powerful orgasms. Although Margaret was wanking herself for all she was worth, Brian was obviously trying to hold back; but when Margaret inevitably came and her anus contracted on his cock, Lucy felt his prostate swell and harden, and she frigged it very hard and pressed her finger into it as he started to squirt.

Brian had never ejaculated with such shattering force before. The pressure Lucy applied to his spunk node and the presence of her finger up his bottom massively amplified the sensation of his sexual organs squeezing the spunk out of his throbbing cock and deep into Margaret's dark and feculent arsehole.

Margaret was thrilled by filthiness. Through the electrifying blast of her orgasm, she felt his cock disgorge his come up her bottom. She was a gusher, and she felt her own juices run through her fingers, for she continued to reach behind herself to stimulate her vulva; her fingers, indeed, encountered Lucy's, who was pulling and squeezing Brian's testicles with her free hand as though trying to milk every last drop of come out of his body.

Spent, Brian gasped and shuddered as he felt Lucy pull her finger out of his anus, and shortly afterwards he slowly withdrew his befouled penis from Margaret's bum.

"Sweet Jesus," he gasped, his attention entirely on Margaret. "That was an experience."

She nodded, so out of breath she couldn't speak. "It was out of this world," she said.

"Are you OK? It's a good job Lucy was here or I might have hurt you."

"I'm fine. You could've fucked me harder."

"Not with Lucy massaging my prostate," he told her. "Good grief, Lucy, you're very good at that. I thought my balls were going to come out of my cock when I spunked."

"Glad to be of service," she said, genuinely. "Just be careful in future!"

"I will," he said. "Phew, I need a drink!"

"And I need to get going," said Lucy, picking her knickers up off the floor and hoisting her skirt as she put them on. Brian had enjoyed seeing his old friend's cunt for the first time, and hoped that she would be participating in their next sexual experiment. Margaret stood up too, a little unsteadily, and he watched his come streaming from the dilated hole between her beautiful bumcheeks. Lucy put her arms around her and kissed her.

"I should go too," said Brian. "I'd better clean myself up a bit first though."

"You're welcome to stay," said Margaret, quickly and hopefully. "If you like?"

It was strange: the women were obviously in love yet she sounded genuine in her invitation for him to spend the rest of the night with her. Not for the first time that evening, he found himself in the unusual position of not knowing what to do.

"OK," he said, reaching for her hand. "Thank you, I will."
