"Your hand!?" Jeff said with a weirded expression printed in his face.
"Yes! It's a bit strange but I saw it on a transformation fetish forum and noted some interesting ones, including the hand"
"Can we try some of the other things?"
"The other ones are even crazier!" She laughed, "we can try them later, you already signed for this hee hee"
"Yes babe... Just start the change"
"I'm for it!" Jenny said while clicking some things looking at the screen and pressing some keys. "And you're supposed to change... Now!" She stated at Jeff, seeing how he suddenly poofed away and his clothes fell on the floor.
Jenny felt her right hand (the one she mainly used) wiggle and hearing the voice of her boyfriend, she moved her arm in front of her as she couldn't control her hand now, the hand twisted moving by itself and revealed its palm side, having Jeff's face in it, Jenny smiled after seeing that her plan worked.
"This is... Very weird, but not that bad" Jeff said trying to get used to his new "body", moving Jenny's fingers and rotating his hand body at least in ways that his anatomy allowed him.
"We can do some crazy things now hehe" Jenny tried to hide her laugh making Jeff wonder what plan she had in mind with her new hand-boyfriend.
