The Siblings (1983) (Better Quality)

Blonde girl with long hair gets on her knees in a dim bedroom, sucking dick like she means it. You see her throat working as the guy leans back on the bed, one hand on her head. Earlier she’s in the shower, soapy hands running over her slim body, water dripping down her tits. Brown-haired guy joins her later — they kiss on the bed, faces close, tongues deep. The blowjob is the highlight, camera tight so you don’t miss a gag or a cheek stretch. Everything’s up close, no wasted shots.
