Y'know, if he slapped both her cheeks simultaneously in a clapping motion, it would be just like John Belushi's impression of a zit in 'National Lampoon's Animal House'...only with cum!

Maybe something to try at the next Gokkun, although I think the clapper should do it from behind because 1) they'll have the element of surprise and 2) they'll avoid the getting the projectile vomit blast of cum being expelled from her mouth all over themselves.

Or how about a slow motion, black and white clip set to classical music a la Scorcese's 'Raging Bull', with the head whipping across from the force of the blow and the gumshield and jizz flying artfully through the air. A surefire AVN winner, I feel, and I just know CAOH/Simp/Windsock would heartily approve!
