Heisse Spiele im Pensionat (1979)

One of the girls has long brown hair and a tight, slim body — she’s on her knees first, sucking the guy hard in the shower, steam on the tiles behind her. He’s got a thick cock and a sleeve of tattoos, standing there with his hand on her head, not gentle. They switch to doggy style against the sink, her ass bouncing as he grips her hips. Later, it’s classroom stuff: both girls in short skirts, one with curly brown hair taking him on all fours while the other watches, then joins in. The camera stays close during oral, really shows her lips stretched. Most of the action’s in the bathroom and a schoolroom with wooden desks, natural light during the day, close-ups when they’re face-fucking or swapping spit.
