Clara started fiddling with options, she had decided that men should have vaginas in addition to their penises, but she also wanted to make certain that they would fully work properly, and that meant changing the shape of their pelvis to be same as a woman's. Looking at the preview the actual change to the size of Jeff's hips wasn't as big as she was expecting, she overlayed his current appearance on top so she could compare, and sure enough his hips would get slightly wider and his legs slightly further apart, and with the overlay it was obvious, but she had half expected womanly hips.
"I guess most of that is flesh" She thought to herself, and then she hit apply and looked over at Jeff.
"Really?" Jeff said, looking slightly uncomfortable as he shifted his weight. He took a few steps. "This feels weird"
"That'll be the pelvis changes, gotta have room for babies!"
Jeff looked horrified.
"I didn't mean now" Clara said, "OK your turn."
She stood up and got out of his way as he sat down. She was pacing around the room when Jeff's changes kicked in. She felt it at first as a strange pressure on her upper groin area. "Did he...?" She thought. And very rapidly it became apparent that he had, in less than a quarter minute she had a penis and testicles above her vagina. For a moment her underwear and pants were squeezing her new anatomy in a very uncomfortable way before they changed to fit her new parts, panties changing into something resembling men's briefs and her jeans changing cut to leave a bit more room in front.
"What do you think?" Jeff said.
She looked down, and pulled the waist of her pants and underwear away from her body in an attempt to get a look at her new equipment. "I dunno... might have to try it out before I know what I think properly."
"Well I know from the preview that you're a grower not a show-er so you're not gonna get a good idea of what you've got down there at the moment."
"Oh?" Clara said, "Then I'll REALLY need to have proper test!"
