Someone's in the house, and they're outside the shower!

You pause with your hands halfway to exploring your breasts, cocking your head to figure out what you heard. A creaking of a floorboard notifies you of someone coming up the stairs, and you can tell that it's not your sparrow-thin mother making those heavy footfalls.

The sound stops outside the open bathroom door and your heart beats extra-fast, adrenaline kicking in. Has someone broken in? Did your mom ask that perv of a neighbor to come inside and do whatever it was she'd been calling about? Or worse, maybe it's your sister in your body about to blast you to hell and back for being naked in her body. Or maybe it's a ****, come to ravage your body, to fuck you senseless in every way until you can't stand up straight and leak sperm like a punctured water balloon.

A moan escapes your lips, surprising you and the person outside if their sudden intake of air is anything to go by. Somehow your nipples have stiffened and your sex has begun to tingle with excitement.

Outside the glass door of the shower you hear the the person take a step toward the tiny little cubicle. Only that door, made translucent by steam, keeps your naked body from the eyes of whoever it is.
