Wonderbolt changing room

Rainbow was a wonderbolt, a fact that she was very much proud of. They were the school soccer team and often won. She walked into the girls changing room with spitfire, they were the only two who were they're, that was because they were half an hour early to practice. While rainbow was a bit worried about her body (small tits) but she didn't mind stripping off in the changing room next to spitfire, the captain of the team. She was wearing her usally clothing of a pinkie and white skirt, black leggings, baby blue boxer shorts, a shirt T-shirt and a blue jacket above. She didn't wear bra's because even the smallest just fell of her flat chests. She pulled down her skirt to her ankles and picked it up and put it into her locker. Spitfire had took off her T-shirt to expose a pink bra. Rainbow took off the the leggings, she was now showing off her boxers. She heard a giggle. She turned and saw spitfire.

"Sorry dash, I always giggle when I see your boxers, you should wear panties some time. The fact you don't wear bras, have no tits and wear boxers is making rumours that your a guy" she said. Rainbow blushed and pulled down her T-shirt to cover them a bit.

"I-in no guy, I just don't thing bra's or panties comfy." She said. She saw spitfire smirk but all she did was pull down her down pants, showing off a matching pink thong. Rainbow continued and took off the jacket and T-shirt and put them in her locker and making sure to cover her nipples. She was all but naked apart from the boxers. She felt a tap on her back and she turned.

"Hey dash I dare you to give me your boxers in exchange for my thong. I will take a picture of your pussy to prove your a girl" she said smirking. Rainbow was shocked, why the hell did spitfire think she'd agree. "Unless your a perverted guy with a werid voice" added spitfire. Rainbow felt angery

"That's it, I'll prove I'm a girl once and for all! But you can't share the pic, got it?" She said. Spitfire nodded devilishly. Rainbow had uncovered her nipples and hooked her thumbs into the waist band of her boxers. She started to pull them down when.
