They may look like elegant ladies, but legendary pornographer Rocco Siffredi named the movie "Rocco's Dirty Girls #7" because its comely performers get off on filthy behavior, including threesome sex with heavily hung studs. Wearing a sexy maid's outfit, long-legged Lina Mercury fingers herself. Caramel-skinned Frida Sante and star fucker Erik Everhard make it a menage-a-trois. Erik stuffs his boner deeply up Lina's tight butthole, leading to an ass-to-mouth blowjob. Anal gaping savant Isabella Clark exposes her plump titties to her bodacious assistant, Candy Cherry. Candy fills Isabella's cavernous sphincter with a clear butt plug. Chris Diamond's big cock shoots a sticky load into Candy's mouth, and she snowballs the spunky mess onto Isabella's tongue. During a photo shoot, curvy Elena Vega and toned redhead Charlie Red squeeze each other's phat ass. When Erik notices the lesbian shenanigans, he joins the models, fucking Elena's pink twat while voyeuristic Charlie masturbates. The three-way climaxes with the girls swallowing Erik's dripping sperm. Pig-tailed Asian princess Katana can't wait to play with her latest boy toy, Johnny Pag. She fellates his meat lovingly, swirling her tongue on his dick head. He pounds her pussy to an intense orgasm. Rocco Siffredi's "Rocco's Dirty Girls #7" is a single-disc DVD with cumshot recap, cast list and filmographies.
