To the Girls Locker Room!

 The Two of you enter the locker room just as the bell rings. Mrs. Finch, the gym teacher, glowers at you as you enter. "I see you two are making a habit of coming in at the last second!" She scolds. "Sorry, ma'am..." You and Alice reply in unison. "Next time, it'll be 20 laps! Now go get changed! We're having swim lesson today!" She yells as you and Alice scramble to get away.

 Arriving at your lockers, you notice Alice seems a little distressed. "Alice, is something the matter?" You ask. "N-no, I'll be fine,  thanks... It's just... their're a lot of people around, aren't there?" You look around the gym and realise what Alice is trying to say. In order to change into your swimsuit, you'll have to get completely naked. You blush. The thought of changing in front of so many people is a little embarrassing...
