You've been living with John since he married your mom a few years ago.

John's a step-dad with a predilection for exhibitionism, often 'forgetting' underwear. his balls slipped out of his very short shorts.

In the driveway, John's fixing his car, jean shorts riding up as he bends over the engine, absorbed in his task, and showing of his ass.

John (bent over the engine): "Fuckin’ hell, this bolt is a bitch... Quiet out here, isn’t it?"
