Sage was walking through the school, looking for a bathroom. He had to poop really bad. He'd been holding it for half of English class, and he was going to burst if he didn't find a bathroom. Luckily, he saw the bathrooms just down the hall from where he was. He ran as fast as his legs could carry him toward the nearest bathroom, dashed inside, and went into one of the stalls. He locked the door, pulled his pants down, and sat on the toilet. He let out a sigh of relief as his poop fell into the toilet bowl.

As he was doing his business, Sage looked down at the feet in the stall next to him. He saw that the feet were inside of pink shoes, and the pants around the person's ankles had a pair of panties inside them. Sage looked at the feet under the other stall, and those feet were wearing high-heel shoes.

"Wait," Sage muttered to himself. "Is this...the girl's bathroom?"

As he said it, his butt grew bigger in a heart shape. His hips widened as well. "What's going on?" Sage asked as he saw his legs lengthen, with their hair disappearing. He realized that his voice was higher now. "Was that my voice?" he asked as he touched his face. He felt his lips getting bigger, his nose shrinking, and his face rounding out. His hair grew out until it reached his butt, while turning blonde. Sage felt something on his chest pushing against his arms, along with a pull from his groin. He swept his hair out of his face and looked down. He saw that, where his familiar male genitals should be, a flat vagina was instead.

"What just happened?" Saige asked as she sat back up. As she did so, she felt two large breasts bouncing on her chest. "I-I'm a girl now?" All of a sudden, she started to pee. "And I'm peeing as a girl???" She finished peeing, then stood up. After flushing the toilet, she looked down at her boy clothes. "I'm gonna look so ridiculous in boy clothes," she complained. As she said it, her clothes started to change. Her shirt expanded into a black dress. The sleeves disappeared, leaving two small straps. Her pants slide back up, with her boxer shorts turning into panties and her pants riding up her chest and forming a bra. Her socks and shoes shifted to accommodate her newly shaped feet.

Saige walked out of the stall and washed her hands. While she was doing so, she saw her new face in the mirror. She looked so cute now, so innocent, so...

"Turned into a girl?" a voice asked.

Saige looked up to see Olivia standing in the bathroom door. Olivia was a girl she knew who went to this school. "How did you know?" Saige asked.

"I saw Bailey and Stephanie walk in," said Olivia. "Then you went in as a boy, and they came out. And I know there are three stalls in that bathroom."

Saige said nothing. Olivia was right.

"Well, I guess we have another girl here at this school," Olivia said, walking out of the bathroom. Saige just stood there, speechless.
