Follie di notte (1978)

A blonde in a tight dress and a brunette with long brown hair start off dancing on a dim stage with tables and chairs, then things shift to a bedroom lit by candles. They’re making out hard, close-up shots showing tongue and grip in each other’s hair. Later scene reveals one guy in a suit watching from a theater box as two women and a muscular guy mess around with restraints in what looks like a dungeon setup. Paper scattered on the floor, some of it might be scripts or props, adds to the surreal vibe. The sex is slow but intense — the blonde rides the guy facing away, doggy style with deep thrusts, then switches to missionary with lots of skin contact. Camera stays wide for most of it, no shaky close-ups, which makes the stage and bedroom feel connected, like a performance that never really ends.
