Director Rocco Siffredi explores taboo relations and freaky fucking behavior among the crazy extended clan of "Lia's Big Stepfamily." The movie features striking Russian/Filipina starlet Lia Lin, who performs in two sex scenes and introduces the others via voiceover. Three step-cousins cavort poolside — slim Lia, petite Tiffany Tatum and tiny blonde Nata Ocean. They strip off their bathing suits and shower themselves in shiny oil to share dildo play and cunnilingus. When their step-uncle, Vince Karter, breaks in on the lesbian fun, his horny step-nieces douse him with lube. In the pool, the girls give Vince blowjobs, and he reams Tiffany's butthole! The pervy foursome moves indoors for slamming intercourse and anal pounding, plus rim jobs, gash grinding and foot fetish. Vince cums on his step-nieces' tongues; Lia and Tiffany orally clean his meat. Step-cousins Ohana Petite and Kylie Green love talking about sex. Kylie opens Ohana's tight box with a dildo. Their step-cousin, Raul Costa, comes out of hiding — he's been spying on the action. Kylie gives deepthroat head. Ohana's shaved box bounces on his dick. Raul fucks Ohana's twat and buttfucks Kylie. Ohana cleans his rod ass-to-mouth. The threesome climaxes with torrential cum facials, and the girls share sperm in a snowball kiss. Gorgeous brunette Valentina Nappi admires her luscious step-niece, Lia, who rocks a red leather dress. Wearing sexy black panties, garters and heels, Step-Aunt Valentina spreads Lia's legs and licks her cunny. In a bizarre twist, a trio of Lia's step-uncles (David Perry, Erik Everhard and Vince) appears, grunting in pig masks! A freaky orgy ensues. David and Erik impale wailing Valentina in a double penetration! Lia rims Vince. The step-aunt and step-niece share a semen-soaked French kiss. European hotties Elisa Calvi, Kat Squirt, Marie Berger and Kitana Lure gather at a lakeside gazebo. Kitana rubs cake onto Elisa's big tits. The girls spray whipped cream onto their bodies as they feast messily on cake. They smear their bodies with chocolate syrup. This Sapphic foursome includes dildo drilling and fervent oral favors flavored with dessert treats! Silly stud Nikki Nutz abets the action, streaming more chocolate onto the deviant chicks. Each girl presses toys to her slit, licks pussy and worships ass in several positions. Elisa stands, unleashing a squirt shower that drenches the other girls! In a foot fetish conclusion, the ladies place their sticky, bare feet together, and Nikki ejaculates on their spread toes! It seems that Ohana has been texting nude photos to Mike Chapman, her favorite step-uncle. She sucks his big Black cock while she rides his face in a 69. Ohana attempts to deepthroat, struggling with the size of his jumbo boner. She takes a ride with Mike's thick prick in her tight, little slot, and she tongues his bunghole. Mike rails her snatch in spoon position while she masturbates. Ohana gurgles up Mike's thick seed and lets it spill onto her cheeks. Blonde babe Carolina Savage confides to Step-Uncle Erik that she wants him to teach her about anal sex! Erik rails her cunt doggie-style, and Carolina takes his big cock way up her asshole. She gives a voracious, A2M head job. Carolina moans as he reams her rectum in multiple positions. Her anus gapes! His spunk drips from her chin as she mouth-cleans his pole. Rocco Siffredi's "Lia's Big Stepfamily" is a single-disc DVD with cast list and filmography.
