A pair of black panties, just then he felt the medallion slide into the stall, Kate must already be changing. Drew decided he better start changing before he found out what else he had in store, otherwise he might back out. He removed his clothes, and set them to the side before he touched the panties to the medallion and instantly felt a shock throughout his body.
The change seemed to start in his crotch, as he felt his manhood beginning to shrink he felt changes start in other parts of his body as well. He stared in fascination at his penis getting smaller and smaller until he was distracted by the appearance of his new breast beginning to push out from his chest.
He reached a hand up to cup the growing mound of feminine flesh now rising from his chest. He felt the tingling of the changes slow and then stop. He continued playing with his new breasts reveling in the strange erotic feelings that doing so created. Then he felt something really unexpected... he felt himself getting an erection.
He looked again at the panties still held in his left hand and then peered down between his breasts to his crotch where he was surprised to see a, pathetically small but, still very male set of genitals, his fully erect penis straining to reach barely more than a couple of inches. "What the hell?" His voice, he noticed, sounded like a young teenage girls.
"Did you say something?" a muffled male voice asked from the next changing room down. "I though we were going to knock to signal when we were ready to come out. Or do you need help getting you bra on." This last part was followed by a masculine chuckle.
"I think something went wrong" Drew said more loudly so that he could be heard clearly by Kate through the divider. He heard the door to the next stall over unlock and Kate step out obviously bare footed. "Maybe you better come in here and tell me what you think happened." Drew called out to Kate unlocking the door to his stall.
"Why madam are you suggesting that you want me to come in there and look upon your naked form?" Kate teased in a horrible imitation of a Victorian gentleman.
She pushed the door open stepped in and closed it again.
Drew gasped at first realizing that Kate hadn't put any of the clothes from the backpack on and was still naked. In the cramped space of the stall they were forced to stand just inches apart from each other, so close that neither was able to see much of the others new body below the shoulders.
"Wow, you are really cute." said Kate staring at Drew's new face with what he thought might be lust. "I know it's probably these new teenage hormones giving me the courage to say this but, I mean it's not like I haven't ever thought about you that way before... it's just... I mean... well I was waiting for you to ask me. You were the guy and all. I guess it's a little old fashioned of me but the way I see it the guy is supposed to ask the girl out. That's the real reason I wanted to trade bags before we changed, see now I'm the guy so it's okay for me to ask you out, right?"
"Um... well" Drew stammered not knowing what to say to this confession of lust.
"So what do you say?" Kate said leaning closer to Drew so that her mouth was right by his ear. "Do you want me?" she whispered gently blowing into his ear. She leaned back again to look into his eyes which had grown wide in shock and obvious arousal.
