Nero veneziano (1978)

A young blonde teen with long hair and blue eyes is on her knees, going to town on a guy’s cock in soft lighting. The guy’s in his 30s, dark hair, mustache, looks lean but muscular — he’s shirtless on a bed, watching her suck him down hard. She takes it deep, face fucking herself with his dick, throat bulging at points. Camera stays tight on her mouth and his crotch, lots of wet sounds and throat gags. Later shots show her on the stairs, still in the same outfit — white tank top, messy hair — like the scene might continue elsewhere. No penetration seen in the frames, but the blowjob is raw and pretty aggressive, not just teasing. The vibe is amateur but focused on the oral.
