Lady X (1980)

The guy is sitting down, shirt off, dark short hair, looks like he’s in his late 20s. She’s on her knees in front of him, wearing white lingerie, dark long hair down her back, slim build. She takes his dick deep, no gagging, just smooth strokes — you can see her throat working on the down motion. Camera stays tight the whole time, almost no cuts, all focus on the blow job. No talking, no music, just natural sounds and the rhythm of her head moving. Background is dark, kinda looks like a bedroom or private space with soft lighting. It’s not flashy, just straight-up oral with good technique and clear visuals.
