Quella Eta Maliziosa (1975)

Starts with this dude in a vest adjusting a black strapon in some garage-looking spot — cables everywhere, tools on the wall. Then you see a blonde in an off-shoulder top standing by a glass door like she’s waiting for something. Cut to the bedroom: freckled redhead in a floral nightgown straddling a guy with a fake bloody nose. She’s riding him slow at first, then gets rougher, slapping his chest. The fake blood makes it look like some revenge fantasy. Later, the blonde in red shorts is running across rocks outside — looks like she’s either chasing or being chased. Camera work is solid, close-ups on the strapon and the freckles during the fucking. Good mix of indoor and outdoor shots, nothing too polished, just raw enough to feel real.
