Primitive Love (1964)

Starts with this skinny blonde chick stretched out on a bed, ribs showing, looking like she’s either about to nap or get railed. Then the camera cuts to her bent over, white guy behind her going full doggy style—no slow buildup, just straight to pounding. The sheets are white with a red blanket bunched up, so you see every thrust clearly. Later, there’s a part where another dude in tribal paint stands with a spear, looking like he’s guarding the action or just vibing in the jungle. The best part? The same blonde gets eaten out by a different guy near a stream, low light making it look all moody and raw. No fake moaning, just real outdoor fucking with a mix of positions.
