Derriere le miroir sans tain (1982) (Better Quality)

A short blonde in a tight black dress gets bent over the bed first, taking a deep doggy from a muscular black dude with a thick dick. Three slim brown-haired white guys take turns on her — one fucks her mouth hard while another jerks off and waits. The scene switches to a 69 with a curvy brunette in a red bra, her big tits bouncing as she sucks one guy while getting eaten out by another. Camera stays wide most of the time, showing the whole bedroom — flowers, handbags, clocks, nightstands, everything feels lived-in. The mirror on the wall gives a reverse angle during standing sex, her back pressed against it while a guy pounds her from the front. Nothing fancy, just steady group action with mixed bodies and no fluff.
