A sex act that involves a female taking a bath/shower and giving a male a hand job while he stands outside the shower. Upon orgasm, the man shoots a load over the female's face/breasts/stomach etc. This technique allows easy clean up for the female and makes her more likely to partake in a cum shot.
Mary hates having my hot load all over her, but I love it. When she was showering she agreed to a tub shot so she could quickly wash my semen off of her body afterwards.
