Tarzan, the Ape Man (1981)

So this shit goes down in some random jungle river, and it’s a full-on group scene. You got a bunch of dudes—some tattooed, some just hairy as hell—and a few chicks, but the standout is this blonde with long wavy hair. She’s slim but not skinny, got that natural tan going on, and she’s taking dick like it’s nothing. The water’s shallow, so you see everything—guys jerking off, chicks sucking cock, and at least one dude fucking her from behind while she’s bent over in the stream. Later, she’s on her back in the grass getting eaten out by one guy while another waits his turn. Camera’s shaky but you get up close on the faces and bodies, so you see every detail. No fake moaning, just raw, messy outdoor sex with a bunch of people going at it like animals—which, I guess, fits the whole Tarzan vibe.
