Double Chunk Waterfall 

When a girl is giving you head, and right before you cum you push your wang to the back of her throat, making her gag, but blocking her mouth, so vomit comes out her nose and runs off your balls, like 2 chunky waterfalls.

Man i can't wait to get off work so i can give my girl the Double Chunk Waterfall
