Hot Spa (1984)

Blonde chick with curly hair and a slim frame is on a wooden bench in a sauna, bent over in a tiny bikini bottom while a muscular dude fucks her from behind. He’s really laying into her, one hand gripping her hip, the other pulling her hair — rough but not brutal. Before that, she’s giving him a blowjob in a bedroom, face deep in his lap, head bobbing slowly like she’s savoring it. Camera stays wide enough to catch the whole setup — you see both of them clearly, no tight close-ups drowning out the context. Later she’s alone on a bed, bent over, wearing stockings and heels, but nothing happens except her just posing. The sauna scene’s the main event — steam, wood, towels, the whole vibe feels private and dirty in the best way.
