Clara and Jeff had been fooling around for about half an hour. Jeff's cock, now hairless and without balls, was engorged and leaking pre-cum all over the place. He fondled Clara's ovaries as they hung from below her labia, feeling the weight of them in his hands and kissing them all over. Clara was extremely turned on at this point but she had avoided all manner of contact with her now extremely sensitive mouth. She caressed Jeff's large sensitive nipples and rubbed the smooth skin of her arm up and down against his cock.
"Are you ready to go all the way?" she asked playfully. "So ready, I could burst" he said with a grin.
With that as her cue, Clara took his prodigious manhood into her mouth and began to caress it with her tongue, gliding it in and out, sporadically creating suction with her lips. Jeff groaned in ecstasy. Clara could barely contain her own rapturous and unbridled pleasure, as her mouth now contained all of the original sensation of her sex organs.
"This must be it," Jeff thought to himself. "She must have made men have much more pleasure during fellatio." Little did he know, that was just a result of her now-amazingly-sensitive mouth wrapped around a hairless member.
Clara was enjoying herself immensely, but decided it was time to bring Jeff to climax. She started taking him as deep as she could, deeper and deeper as she gradually moved her lips to his skin at the base of his penis. He started shuddering and shaking uncontrollably as he passed the point of no return. With little warning, he came down Clara's throat with extreme force and volume. It was an orgasm unlike any had felt before, more powerful and intense, and satisfying on a deep level he had never felt before. He suddenly felt dizzy, as if he had lost a lot of blood, but then the pleasure returned and he felt right again.
Clara raised her head from his groin slowly and looked up at Jeff. Normally, he would have kissed her now, but something was odd. She had something dangling out of her mouth. "Is that...?" he stammered, but it was clear as day what it was.
"I was trying to think of an interesting change" said Clara, removing the object from her mouth. "Then I remembered that there are some species of animal whose penises detach during insemination and I thought it would be interesting to see in action."
Jeff looked down at her hand and sure enough, there was his cock, slightly softened but still near its erect size, sitting in the palm of her hand, still in the midst of orgasmic spasm. It weakly flipped around a bit like a dead fish in her hand, then stopped moving.
Jeff looked down at his now completely-bare groin, and all that was left of where his dick had been was a slightly pink and sensitive depression with a hole in the middle for his urethra to empty.
"What did you do?!?!?" he cried.
