Up Your Ass has all the makings of a dependable wall-to-waller, i.e., slutty girls, big cocks, and a minimum of ad libs. Threesomes dominate the action, and for added spice, they're interracial. The scenes are long, but not too long - taking places in what seems to be just the right amount of time for oral warm-ups and standard penetration. Then we're off to raucous, brown-eyed buggery... right?

Well, sort of. Perhaps it's the big cocks. Possibly, the lube shipment went awry. Or just perhaps, like sharks, the girls have watertight buttholes. Whatever the case may be, the anal penetration portions fall just shy of AAAA monster heat because the guys have trouble laying pipe in the no-pipe zone. Oh, there's gobs of half-penetrated ass to be savored, but not a lot of to-the-very-hilt action. One exception is the Sheila Stone shower encounter, where her partner manages quite well to pack her ass with numerous re-insertions. For added zest, he blows his load onto her winking sphincter... a move seldom seen, but certainly appreciated by fans of the rump-plundering genre.
