A scuba Steve is the act of using a snorkel for sexual pleasure. The goggles are removed (or worn for enhanced breathing), and the breather tube is inserted up the vagina. The mouth piece is then inserted in the anus and a cycle of fart to queef results in a pulsating sensation giving the impression of cum inside and pull out repeatedly.

Rumours are that it allows one to breathe without the need for normal breathing and can be used under water.
Hey Stacey are you coming out tonight? “Nah I’ve got a date with scuba Steve tonight, I’m practicing cyclic breathing”.
