charizard's tail

When a guy uses gasoline as lube and gives anal sex to someone and after he finishes lights the gasoline and penis aflame while it's still inside his partner

Last night me and Stacy did charizard's tail.

Pikachu's tail

When your partner has a metal butt plug in their ass and you take a tazer and taze the metal base randomly thoughout sex

When my girl friend said we should try Pikachu's tail for the first time I have no idea what I was getting into
