Prostituzione (1974) (Better Quality)

Starts with this dude in a full animal-skull mask and tattoos setting up what looks like a dungeon altar—candles, skulls, the whole goth vibe. Then a slim brunette with shoulder-length wavy hair and a tramp stamp walks in. She strips down to a black dress while he watches, then bends over the bed for doggy. Mask stays on the whole time, which adds to the weird energy. She rides him reverse cowgirl later, tits bouncing, and he grabs her hips hard enough to leave marks. Room’s dim but you still see everything—good close-ups on her ass and his cock sliding in. Not your usual bright studio shit, more like a horror flick with better sex.
