Clara sat down at the computer, feeling the strange sensation of her enlarged clit settling between her legs, the tip resting on the seat of the chair.
"That could get distracting" She thought as she started digging through menus.
It took several minutes, but she managed to do what she wanted, give men a vagina like spot above their penis where a woman's clit could go during sex. It would normally be fairly shallow but during an erection it would enlarge and the back wall would get pulled back to deepen the space. It would also, if the man was sufficiently aroused self-lubricate and get wet, with pretty much the same fluid as a vagina does. She also ended up re-arranging some muscles so that men could squeeze the same way women can. And she had made it sensitive, though most men wouldn't be able to orgasm from "vaginal" stimulation alone, much like women. On the outside the new part looked mostly like a simple slit, a vagina with small labia, it was slightly shorter than a vagina, and ran right down to the top of the penis.
"This will make just having sex a lot more fun" She thought. "I'll be able to cum just from him fucking me a lot more easily now. Quickies will be much better!"
She hit apply and turned to watch Jeff's reaction to her handywork.
The actual change happened very fast, Jeff felt it start and it was over, reached for his dick to check it was there, found it was, and looked down, and saw nothing but his boobs. With his hands on his dick his arms were pushing his boobs together, so he stood and looked in the mirror.
"Oh, what's this?" He asked, again reaching down, this time touching the new slit above his dick. He was surprised when he tried to slip a finger in and it didn't go very far, since he had lost his erection waiting for Clara to make her changes.
Clara quickly explained.
"Well that's a really neat idea, I think it's even better than just giving men and women both functions." Jeff said. "I wonder what it'll feel like."
"We can find out if you like" Clara said with a smile, and she stepped up to Jeff put her arms around him and grabbed his but feeling her boobs pressed against his. "Or you can take your turn."
She had been thinking about how it would feel to have sex with all the changes, and Jeff's boobs had become distracting to her since changing men to have them had naturally changed women to like them the same way men did, and her clit was half-erect. She could feel Jeff's now partially erect penis against her body, and it was turning her on.
