gender bender
Annabelle

One day, your two closest childhood friends, sisters Annabelle (right) and Cassandra (left), call you up. They live one state over. They are on their school's girls' swim team, and it is loosing miserably to the other schools in the state.
The girls remember that you were always a really amazing swimmer back when they were younger, before they moved to the other state. They checked the swim league's anti-descrimination bylaws and discovered that even though it's a girl's swim league, they're not allowed to discriminate based on gender. They checked with the officials, and you'd be allowed to join, as long as you dress and act and self-identify as a girl for the duration of your involvement.
Your friends beg you to come to their rescue. Your parents encourage you as well, saying it would be great on your résumé. And the principal of their school offers you a huge financial incentive. It's just for one semester.
You show up on try-out day and are handed the regulation team swimsuit, which a seamstress has somewhat adjusted to accommodate your anatomy. You're really embarrassed to wear it, but everyone at the pool - literally everyone - looks at you as their hero, their savior, who's going to save their school from the shame of losing the tournament yet again.
Can you handle it? Can you swallow your pride and be a 'girl' for the semester, and help the swim team?
