Friend: what was it?
Me: sperm Whaling

To get a head in a hot tub from a girl with a trachea and when you are cuming you jam your dick down her throat so that when she comes up from under water she blows your load out her trachea like a whales blowhole.
Curtis: Hey man, I made Tracy with the trachea do the "Sperm Whale"!
Nate: No way, "Sperm Whales" are the shit. Almost as good as a blumpkin.
