Sexual Insanity (1974)

Eliza Grant is on her knees first, wearing red lipstick and nothing else, stroking a guy’s dick while looking up at him like she’s about to take it hard. The guy’s chained to a wall in what looks like a dungeon, muscular, short brown hair, sweating under dim red lights as Hunny starts riding him reverse cowgirl. Camera stays close — you see every thrust, the way his abs flex when she grinds down. Ruby Tuesday steps in next, swapping places, taking over with a tight pussy that makes him groan loud. They switch up positions — doggy, then missionary, then a nasty blowjob where Eliza deepthroats while Hunny jerks him off and Ruby watches, stroking her own clit. The whole thing feels raw, no fluff, just thick bodies moving fast, sweat mixing with lube, loud moans echoing off stone-looking walls. Not much aftercare, no talking — just sex from start to finish.
