The Cream Filling 

During Sexual Intercourse, when about to jizz, pull you dick out and jizz in between the girl's boobs.

Guy - oh yeah baby, want the cream filling?
Girl - oh yeah, give it to me nice and creamy!!!
the rest is pretty self explanatory.

Spillin' the Cream Fillin' 

Another term for masturbating or jacking off (flapping your "noodle" so that you ejaculate resulting in pleasure)

Guy 1: Hey why weren't you out with Monica yesterday?

Guy 2: Because she won't suck me off, so I decided I would rather go spillin' the cream fillin'.
