Websters defines hygiene as cleanliness. Well, there is absolutely nothing clean about Oral Hygiene #5, a Rob Black production. This is strictly an all-oral flick in which two guys abuse 10 girls in about as many ways as possible. Besides cocks, the girls must suck feet and hands and fingers. They are gagged with dicks, choked, and slapped until they are nearly vomiting and mascara is running down their faces. Not a pretty sight! Each girl is interviewed before each scene, and Im assuming it is Black who does the honors. Ive never met the man, but if his speech and thought pattern are consistent with these interviews, he is probably apt to say at any time, Dude, what a gnarly fucking hummer that was. Tubular, dude! Just to warm you up for the blowjobs, the girls answer questions in a most candid way. It is revealed to us that, among the many other tragedies in their life (like sucking feet to pay the rent), they have endured drug addiction, pedophile fathers, brothers in prison for life, mothers who were porn stars, and hooking at age 14.
