"OK then. I'll try and see..." Brian made up his mind. As he took his own trousers off, he heard a shuffle outside the door, which reminded him of his semi naked state. Grabbing his bag, he hurried into a stall, having to hold his new-found breasts to stop them jiggling uncomfortably. He locked the stall door just in time to hear some people enter.
"So, I told him he should just stuff it and go away. I'm not going out with him!" It was the voice of Bethany, the girl Brian had been going after for a while now, and he knew exactly what she was talking about. What he didn't know what who too, and then, a second thought: what was she doing in the disabled toilets? He took his legs up onto the seat and hugged them close against his body, feeling awkward as his breasts squished against his chest.
"Hurry up and get ready, Alice. We're running out of time, we shouldn't be here anyway, and how did you manage to lose your sweatshirt, anyway? And your pants? That's just stupid!" Bethany shouted, causing Brian to gulp. He had Alice's clothes, Bethany's best friend's clothes!
With a shuffle from the next stall and a few muttered words, the two girls left, leaving Brian shaking slightly.
"Oh crap!" He thought. "But wait... I have Alice's clothes, so I can get close to Bethany... And convince her to go out with me when I get back to normal! Excellent!" He hastily stood up and put the sweatshirt back on, beginning to enjoy its feel against his nipples.
Next, he removed his old pants and put on the sweatpants. He fell to floor as his body squirmed. He opened his eyes and looked at his lower half. It had become more slender, the legs longer, the thighs bigger. His waist and hips had sorted themselves out, but most importantly, he discovered a final change when he reached beneath the pants: his manhood was gone! It was replaced by a sexy slit with little pubic hair. When he withdrew his hand he noticed that his underwear had changed too; they were now silk panties that felt so soft against his - or now, her - female skin. His shoes had changed to match the pants, along with socks, becoming more well fitting to her new shoe size.
Finally, she felt something supportive around her chest and pulled the sweatshirt enough to see a bra neatly covering her breasts.
"Neat." He whispered to himself before getting up again and walking out the stall. And the froze again. Bethany was there waiting for her, an irritated expression on her face.
"Oh, so you did have your clothes, hm? And why didn't you tell me?" She asked angrily.
"Oh, well... uhh... I don't know, sorry Beth." Alice replied uncertainly. "Sorry for wasting time. Come on, let's get out of here. We have stuff to do."
