So me and my boyfriend were upstairs in his bed room having sex. And we hear footsteps coming up the stairs so I get off of him and we lay under the blankets and pretend to be watching a movie and his step brother who is 2 years younger then us walks in after his shower with a towel wrapped around him and goes " don't look I'm naked." As a joke not realize we actually were under the covers. Then he looks at us and turns around and walks out and all you hear is him go "WHYYY" and we start laughing so hard.
