Angels of Mercy (1985)
One of the brunette girls has a slim build and small tits, sitting on the bed giving a blowjob while the other just watches. The guy lies back, hands on her head, not much movement — it’s a slow, relaxed oral scene. They switch to kissing afterward, both girls pressing against him, lots of tongue, faces close. Later there’s a cuddling shot in what looks like a living room, bookshelf in the background, but no sex there. The camera stays tight on their faces during the blowjob, focusing on her mouth and his reactions. Pretty basic setup, no fancy angles or lighting beyond the natural bedroom window glow.
