Sengo Ryôki Hanzaishi (1976)

Dude with a short dark brown cut and a bit of scruff starts things off by eating out a slim brunette with long wavy hair. She’s got that just-out-of-bed look, all loose waves and smooth skin, and she’s really into it—legs spread wide on the bed, back arched. The camera gets right in there, low angle so you see everything. Then the action moves to the couch where he’s pounding her doggy style while her friend, another brunette with shoulder-length hair and a choker, watches close-up. She’s got a tighter frame but still curves in the right places. The guy’s got a solid build, not jacked but toned, and he’s got stamina—no quick finish here. Lighting’s dim but you still see all the details, especially when he pulls out and you get a clear shot of his cock. No fluff, just straight-up fucking with good angles and two girls who look like they’re actually enjoying it.
