Nureta yokujo: Tokudashi nijuichi nin (1974)

This one’s packed—21 people, mostly Asian chicks with a couple of Black dudes mixed in. The setup’s a big group scene, but the focus is on the blowjobs. You’ve got slim Asian girls with long dark hair and wigs taking turns sucking dick, some deep-throating like pros while others just tease the tip. The camera gets right in there, close-ups of lips wrapped around cock, saliva dripping, and a few girls gagging but pushing through. One Black guy’s got a thick one, and the way the girls fight over it is messy in the best way. Lighting’s dim but you still see everything—no fancy editing, just raw, sloppy oral action. If you’re into big group scenes with a lot of variety in how they suck, this one’s got it.
