Sweater Girls (1978)

One of the girls has a tight blonde bob and small tits, she’s the first to go down on the brunette with long hair. They start with missionary, the blonde taking it slow while the redhead fingers herself on the side. The brunette then flips the blonde onto her knees for doggy style, pulling her hair between deep thrusts. Later, the redhead rides the brunette’s face while the blonde jerks her own pussy standing up. Camera stays wide most of the time, no quick cuts, lets you watch the whole thing unfold. The tapestry on the wall behind them flutters slightly when the couch moves hard.
