Karyn looked at Jon's new chest and grinned slightly. Jon felt uncomfortable, the boobs were heavier than he was expecting.
"Wait there for a second!" Karyn said.
She ran out the door into the bathroom, having grabbed the stone without Jon noticing.
"I wish that I had the same power as Jon, where my body would reshape itself to match clothes that I'm wearing." She said as she took her pants off.
Quickly she slid her panties off and put her jeans back on. She ran back to Jon and found him with the bra off looking down at himself, cupping his breasts.
"I'm back Jon-boy!" She said holding up the panties.
Jon turned around, and saw what she was holding.
"What!" Jon said.
"C'mon it'll be fun! You can just put your own clothes on to go back to normal whenever you want."
Jon looked at her surprised. "Why?"
"I wanna know what you think about how it feels"
"Huh. Alright then, I guess."
Jon took the panties and headed for the bathroom to change. While we was gone Karyn quickly rummaged through his drawers until she found a pair of his underware. Quickly she took off her pants and put on his underwear. She could feel herself change, she watch the bulge grow in her crotch and felt her hips narrow adjusting to Jon's size. She pulled the elastic waist band out away from herself to get a look at her new package.
"Not bad!" She thought, then she felt a new sensation as she got a hard on, she saw her penis grow out to 7 inches long and thicken out, it was thicker than she expected.
"Wow, is that really what Jon-boy's packing down there? Maybe I should re-consider my no dating Jon policy... Hell I could try to convince him to try things out as we are now." She felt herself get harder, though not any bigger, it felt slifghtly unconfortable and she was quite turned on.
"Wow so that's what that feels like... I'll have to think unsexy thoughts, don't want Jon thinking I'm a complete perv." She thought.
After a moment it worked slightly, she wasn't uncomfortably hard anymore, but she was still tenting out the underwear.
"Unsexy thoughts. Jeas it has a mind of it's own."
Then she sat on the bed and waited, wearing only a T-shirt and Jon's tighty-whities.
