House of the Licking Sun (1990)

A brunette in her 20s with a slim frame and short brown hair is on her knees in front of a muscular guy with defined abs and a tattoo on his arm. They’re in a dimly lit living room with a plant in the corner and a leather couch nearby — clothes already scattered on the floor. She pulls out his cock and starts jerking him off slow, then takes him deep in her mouth, cheeks sinking as she bobs. The camera stays tight during the blowjob, catching every wet noise and swallow. He grabs the back of her head, pushing her down harder, and she keeps going until he flips her around and she ends up on the couch, skirt pushed up, taking it from behind. You see her face during it — not faking anything, eyes half-shut, breathing heavy, clearly into it.
