Disc-Jockey at K-Sex (1978)

A slim brunette in her 20s starts on her knees, deepthroating a guy on a dimly lit bed. You can see her gag a little as he pushes deep — messy, real-looking saliva drip. Cut to a living room scene where a curvy blonde in her 30s is sandwiched between two guys, getting fucked from behind while sucking the other one dry. Later, the same MILF is on all fours in the bedroom, taking long strokes from behind, then flipped onto her back for creampie shots. Lighting stays low throughout, mostly close-ups during oral and doggy, wide when the group action kicks in. The guy’s physique is lean but defined, matches the younger guy on the couch who barely says a word but keeps thrusting hard.
