Slim brunette in basement gets chained and fucked rough

Close-up on a young woman’s face, chained to a wall in a damp basement — peeling paint, dim light, her dark hair hanging loose. She’s slim, maybe early 20s, wearing nothing, wrists pulled wide with chains. Another shot shows a muscular guy in his 20s, same dark hair, standing over her with a tool in hand — looks like a wrench or pipe — but it’s not used violently. They’re in some kind of confrontation, tense, but it shifts fast. Later scenes cut to a studio-style setup with high-contrast lighting: she’s bound again, on her knees, but now it’s clearly sexual. The guy is restrained too in some shots — chained and gagged, lying under a hard overhead light. No faces fully clear, no names shown, but the visuals are consistent: dark-haired, twentysomething performers, slim build on her, muscular on him. The basement scenes feel gritty, almost survival horror, but the studio shots are pure porn — tight close-ups on lips, gags, chain links pressing into skin. Camera work is low-angle during her kneeling scenes, emphasizing submission, then overhead when he’s down — gives a sense of total control. Not much movement in the sex acts — more about poses, bondage tension, the sound of metal creaking. She gets mounted hard in one frame, legs up, but it’s implied more than shown. Most of the heat comes from restraint, the look in her eyes, the way the light slices across bare skin and rusted walls. The shift from dungeon to studio is weird but deliberate — like a fantasy playing out in stages.
