Hang Job

When a girl (or possibly guy given sexual preference) performs a hand job on the male. Just when he is about to cum, she stops and walks away leaving the guy unfinished. She then rushes back and jerks him off as hard as she can till he busts.

Dude this girl was giving me a hang job last night, and just stopped out of nowhere and left the room ... then she rushed back in with an outstanding finish.
