You head to the bathroom to take a shower. When you open the door, there's a guy standing there. Naked. You drop your change of clothes before slamming the door shut.

"Learn to use a lock!" You yell.

You head to the livingroom where you see your brothers hockey team. "I invited my friends over." he said.

"Too late to tell me now." You mumbled

A few minutes later the guy finishes showering. "Are these yours?" He smirks, holding up your red set of lingerie.
