In the locker room...

Thanks to the brown pen, David entered the girl's locker room and walked right to Allie's locker like she had always done before. Nothing seemed out of the ordinary to any of the other girls as David opened Allie's locker and pulled out her track bag before beginning to remove his tank top and skirt. Pulling the ruffled white skirt down to his ankles and stepping out of it, David finally snuck a few glances at the girls around him.

One locker down was Katie Hunt, his girlfriend's little sister. She had just joined the track team this year but she was already a good addition to the team. She was talking to another sophomore and had her back towards David at the moment but he knew her by her voice. Katie was wearing tight spandex shorts and David couldn't help but notice how great her butt looked in them. He had always thought she was cute but her short time on the track team had already started to tone the girl's body. As she started to put on a spots bra David turned back towards Allie's locker and grabbed a pair of tight black spandex shorts to put on himself. Deciding to keep Allie's thong on, David stepped into the spandex and pulled the garment up his shapely legs until it was snug against his crotch. He then took off Allie's bra and donned the athletic shirt she had packed that morning, letting Allie's body go through the motions basically on auto pilot.As David took a seat on the bench to tie up Allie's running shoes Rachel came over and sat down next to him.

"Hey, you were almost late for practice! what's up? Is everything okay?" she said, a look of slight concern on her face.

"Oh hey Rachel, everything is totally fine. I just had to speak to Mr. Henderson quickly about the exam next week" David responds, glancing back at her and smiling.

"Ugh, I hate having to go see him outside of class. I can always tell he's checking me out through my clothes." she says before standing up to head towards the door.

"I know! He's such a creep!" David says and then he giggles, as he checks out her ass with glee. Standing up, David assumes Allie's role of sprinting team captain and tells the rest of the team to meet outside in 2 minutes to start stretching for practice. Then he and Rachel head towards the door to the athletic fields behind the school. David smiles as he opens the door and lets Rachel exit first, nobody was suspicious that he wasn't actually Allie Davidson.
