The Fishy Straw

When a man sticks a bendy straw into a girls pussy and blows, therefore creating variants of brown, orange, green, (and if you blow hard enough) red bubbles that come out of her ass and someone on the other side tries to pop them with their mouth.

Guy 1: bro I just did The Fishy Straw to my girlfriend.
Guy 2: who ate the bubbles?
Guy 1: my twin little sisters
