Girls Of Treasure Island (1988)

Blonde with long hair and massive tits is on her knees first thing, deepthroating a muscular grey-haired guy with a sleeve tattoo. He’s thick, and she gags a couple times but keeps going, spit running down his shaft. They move to the bedroom — she’s on all fours, taking rough doggy while he pulls her hair, then switches to missionary with her legs up. Outside scenes show them fucking on a lounge chair by the water, her riding him backwards so you see her ass bounce. Later, she’s bent over on a dock, getting nailed from behind again, this time with a cumshot on her back. The whole thing’s shot in natural light, lots of medium and wide angles that show the locations — beach, boat, pool area — without cutting away from the action.
