When a guy calls you into the bathroom to bring him something and you walk in on him in the bath, lounging, fully erect. Not touching himself or asking you to join, just wanting you to be in the room.

The head of his penis bobbing up and down like the periscope of a submarine.
Oh my gosh, Mark is such a creep. He asked me to bring him his phone and when I got to the bathroom he was just laying in the tub periscoping.
