I never thought he'd see me naked...

I’m home from college for Christmas, stepping into the shower when everything falls apart. Cold water shoots everywhere. I lose my balance and grab onto the shower curtain, but fall anyway. Of course it’s my stepdad who busts down the door, chest heaving as he assesses the situation. I’m naked and shivering on the floor. I thought I’d die of humiliation until I realize he’s hard as a rock.
