Manufactured Misfortune/Day1-Anatomy Afternoon With Emily
You've certainly been having an interesting time with your sister, to say the least, so you think you'll spend the rest of the day with her. Knowing Emily she probably ran straight home and arrived before you even left the school grounds, so you aren't surprised to not see her up ahead as you walk.
Soon you arrive at your house. It's a simple two story design with a basement, garage, cramped attic, and decently sized backyard. It appears neither of your parents are home yet as the driveway's empty, and as you enter through the garage like normal you see that it too is empty. As you exit the garage and enter your house proper you hear the shower kick on upstairs just as you close the door. Normally you wouldn't think twice of this, but for some reason it seems louder, more clear than normal. Curious, you make your way upstairs, tossing your bag into your room as you pass, and are shocked by what you see.
Evidently, Emily must've thought you'd be taking a while after school, because she left the bathroom door wide open while taking her shower. Carefully you walk up to the door and poke your head inside. The upstairs bathroom was larger than the one in the basement (which was no bigger than a large closet really), with the door on one end against the left wall, a large bathtub and curtain against the right wall, a toilet nestled between the tub and outer wall in the corner, a two person sink against the inner wall, and a very tall and wide window on the outer wall. A large, circular, waterproof rug took up most of the floor space.
You always thought it odd how the towel rack was on the left wall, the opposite side of the room from the tub/shower, which meant everyone had to put their towel on the counter otherwise they'd walk naked past the unusually large window (something the neighboring kids would certainly enjoy). However, that was far from you mind, as even though you couldn't see through the curtain you still could hardly believe Emily was just casually showering away with the door open, not knowing you're there.
Perhaps it was the anticipation of what you and X were plotting, or maybe you were just that naughty minded, maybe both, but your mind was filling with ideas on how to have some fun with this. She just got in as you got home, meaning you have time to prepare, so what shall it be? You could just peep on her, but that's a bit simple. You see her towel on the counter and the large window taking up half the wall, you know her room and phone are left unguarded, hell, you could even strip down and have a look, Lord knows you're horny enough to even consider it.
Or you could just whistle as loud as you can and scare the piss out of her (literally, you've done it before). Granted, that'd give you away immediately, but it'd be funny as hell.
As your sister sings one of her favorite songs in her lovely singing voice, you know you need to decide, now.
What will you do?
