dusty rainshower
During the act of sexual intercourse between a man and a woman in the missionary position, right before reaching orgasm, the man will quickly pull out, spin around, park his ass right above the face of his lover, and begin to fart repeatedly while climaxing and spraying his semen up into the air so it rains down over his lover's breasts, stomach, and pelvis.
I took this fat nasty home from the bar last night, she said she wanted to rim me, instead I just gave her an unexpected dusty rainshower. She chuckled heartily.
