Your parents' pool

You've just graduated from high school, and are staying with your parents for the summer before you go away to college. They're both at work, so you've been home alone, desperately looking for distraction from the miserable heat. Though it's your last resort, you can't deny how nice it would be to take a swim in the pool right now.

You head to your room to get changed. Given how little you swim, you only have two choices for attire; a black single-piece from way back when you used to be on the swim team as a kid, and a blue bikini that your mother insisted on buying for you before you started high school, because she knew it's what all the other girls wear. You've only worn it twice before, you tend to prefer the single-piece because of its coverage, despite how tight and uncomfortable it feels to wear after all these years, but you're uncomfortable enough as it is.
