Do a girl doggystyle. Cum on the small of her back. When it runs down into her ass crack, slap both ass cheeks together, thus creating an eruption.

A sex act in which a girl gives you head and holds a lit lighter until you are about to cum. She then extinquishes the lighter on your scrotom as you cum thus creating a 'fire from down below' eruption effect.
