Volcano Roll

Coating your penis in hot sauce and subsequently performing anal sex on a woman

Electric volcano

This advanced sexual maneuver should not be attempted by anyone, ever. The maneuver begins in the 69 position with the man on top. After a few minutes, either partner yells ELECTRIC VOLCANO. The female immediately puts 4 packs of pop rocks in her mouth and resumes fellatio. The male grabs a fresh 9 volt battery and holds it to the clitoris only for a few seconds causing a volcano eruption each time.

I heard a couple of olympians attempted the ELECTRIC VOLCANO and both died, they should have headed the warning.

Human Volcano

While in the act of sex the male is putting it in the girls ass and just as the male ejaculates into her ass he pulls out and the female farts causing cum to fly out everywhere simulating the eruption of a volcano.

Dude, i heard about jenny getting the human volcano from brad last night...he said there was cum splattered all over the walls.
