Haunted by a college memory of watching her hung step-brother, Conor Coxxx, fuck a girl silly in the backyard, Alexis James remains fixated on his impressive cock. Now sexually adventurous, craving anal and double penetration, she schemes to seduce him. Posing as a last-minute photoshoot for her company’s revealing outfit, she arrives at Conor’s place, her plan to wear nothing underneath the skimpy attire. A little earlier, alone in bed, Alexis indulges her obsession, masturbating with a toy in her pussy and ass, then adding another for a frenzied double penetration until she climaxes. Later on, Conor, sipping coffee, agrees to her photoshoot request, unaware of her taboo intentions. Alexis arrives in a barely-there outfit and heels, shocking Conor with its transparency. Brushing off his prudish protests, step-sister poses seductively, then strips completely naked, claiming she trusts only her step-brother for nude photos. Despite his objections, Conor snaps shots as Alexis spreads herself, teasing her nipples and clit. Sitting on the couch very close to each other and reviewing the photos together, Alexis fingers herself and slyly rubs Conor’s hardening cock through his pants. Ignoring his step-brother protests, she flaunts her wet fingers, proving her arousal matches his. Kissing him passionately, Alexis overcomes his reluctance, unleashing a torrent of forbidden lust. Conor devours her pussy and ass. Alexis returns the favor with a sloppy blowjob, sucking his balls and rimming him eagerly. Their sexy bodies entwine in fervent vaginal and anal fucking, Alexis switching between ass-to-pussy and ass-to-mouth, her fingers teasing her clit as she cums repeatedly, her orgasms loud and undeniable. Conor’s relentless fingering makes her squirt again, intensifying their raw connection. The climax sees Conor filling her ass with a creampie; Alexis tastes it hungrily before cleaning his cock with her mouth. Alexis asks if he regrets their taboo encounter. Conor admits he could get used to it, and suggests they clean up. Stroking his cock, Alexis proposes a shared shower, leading him off with a wicked grin.
