Honeymooners (1976)

The blonde has long hair and a tattoo on her shoulder, thick in the hips, riding the guy who’s balding with a muscular build and ink on his arm. He takes turns fucking her in missionary and doggy while the other brunette, slim with a nipple piercing, gives him head. The lighting is low but the camera stays close — you see every flick of the tongue and how deep he pulls her hair during the blowjob. They switch it up: one scene shows the brunette riding him while the blonde goes down on his chest, licking a scar just above his nipple. The final shot is him jerking off on his own belly, alone on the bed, still hard. Camera work stays tight and steady, focused on faces and action, no cuts away during key moments.
