Captain Butts’ Beach (1992)

One of the brunettes is face down on a bed in a dim room, totally exposed, getting fucked hard from behind — you can see her back muscles tense with each thrust. Then it cuts to the beach, bright daylight, both girls in bikinis lying side by side on towels like they’re posing for a magazine until things turn dirty. The guy shows up shirtless, muscular build, not too ripped but solid, and starts eating one brunette out while the other jerks him off. They switch roles — strapon lesbian stuff, deep kissing, then he fucks the first girl doggy style on the sand, pulling her hips back hard. She takes it well, moaning loud, and later they do missionary under the sun, sweaty and grinding. Final shots show creampie leaking out after he pulls out, both girls smiling like they just got properly used.
