Snow

cum from a mans penis which leaks out of your mothers cock while she ever so slightly strokes it but then it ends up being your penis and your sperm (cum) is now snowing on her face and in her mouth while she sucks it for seven years straight while watching jojo's bizzare adventure while she wanks your cock so much it explodes with snow/cum/sperm in th whole room and your grandparents walk in and now your cock is split into three with your family sucking on it and it's "snowing"!
