Necromania: A Tale of Weird Love! (1971)

The girl’s on her back in the first shot, short brown hair against a striped pillow, looking up like she’s waiting for it. She’s slim with a flat stomach but surprisingly full tits — they bounce a little when she’s on top, riding slow at first before he flips her over. The guy’s got a solid build, hands clamped on her hips, slamming her from behind while she’s braced on the headboard. You see a ring on his hand when they kiss face-to-face, both of them grinding tight, her legs wrapped around his waist. The lighting’s dim but the camera stays close, especially on the oral part — she’s down low, bobbing hard, one hand on his thigh. Feels raw, not staged — like they’re really into the rhythm, no pauses for angles.
