Hot Asians doing white guys until they pop. Rough sex.
This has a lot of raunchy stuff: pussies spread open so far you want to drop a rock in them and wait for the splash, inverted oral and deep throat, anal, group sex, mouths pried open, and so on. The idea of being a Kung Pow Kitty is to be very physical - be it in the sack or rehearsing your best David Carradine impersonation.
Mark Davis gets especially rough with Nyomi Marcela as his pounding, hair pulling, and making her lick it up from the floor attests. And poor Avena Lee has so much energy to expend that she finds the need to take on two guys at once.
Who really directed this is anybody's guess. The box says The Macho Brothers and the DVD's credits list Martin Del Toro.
