Sexy Time Explosion. Is when the man is about to cum and rubs his fingers together in a circle motion and then with both hands using your index and middle finger you poke each of the girls eyes then cum all over her.

That's a sexy time explosion.
S.T.E example:

So, I get under mah goat and pull, back and forth, back and forth, back and forth, for two hours, and finally, he uh, make da SEXY TIME EXPLOSION...HIGH FIVE!!
