Double Waterfall

When two people sit in the toilet together and urinate simultaneously.

My wife joined me for a seat on the toilet to participate in a double waterfall.

Double Waterfall

When a girl is giving you head, and right before you cum you push your penis to the back of her throat, making her gag and vomit, while she is vomiting regurgitate all over her back and head making sure that your vomit runs into her's creating the double waterfall effect.

Put down some plastic so our double waterfall doesn't ruin the furniture.

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.

Double chug waterfall

When a male is receiving oral sex, they shove their penis far enough down recipient’s throat at the moment of climax, that the recipient vomits up both puke and the load

I thought she had done this before, but I went too hard and she gave me the double chug waterfall.
