Model and actress-turned-director Sandra Shine presents another installment of her erotically charged <em>Undercover</em> series. This episode stars Sofi Golfinger, a gorgeous Russian babe with long blonde hair. She introduces herself as a nude model and exhibitionist – Sandra explains that, after shooting a very hot lesbian scene together, they were talking, and Sofi expressed an interest in taking part in the <em>Undercover</em> project. The model confesses that she has never had sex in a public place, and feels shy, but she is tempted by the idea of a little risky business. She then tells Sandra she’s into both whores and boys, and confesses more about her fetishes and turn-ons, then admits she masturbates twice a day. Sandra suggests she could masturbate by a nearby freeway and show off her beautiful dancer’s body – and Sofi finally agrees. The duo head to a footbridge over the freeway and Sofi, although nervous, is very excited. Her hands immediately begin to roam and she frees her small, perfect breasts from the top of her short dress, then hikes it up to expose her black-lace panties and her braless tits. As she poses and caresses her body, a man walks by with a bicycle and she flashes him, twirling to give a glimpse of her stunning bubble butt. Next, she pokes a hole in her panties and rubs her clit before pulling the crotch aside so she can finger her slit. More passers-by cause a temporary halt, but Sofi soon continues, hornier than ever. Sandra captures close-ups as she teases her clit and nipples, circling her fingertips around them. Then, after a cheeky wave to the traffic, Sofi squats down, thighs splayed wide, and strums herself, pausing only when more pedestrians arrive on the scene. Soon, however, she resumes her self-pleasure, probing her juice-drenched snatch deep with two fingers. She cums hard, her moans virtually sobs of delight as her body quivers and spasms. Then she pulls her torn panties back into place, the entire crotch now split open. The duo hang out on the bridge a little longer then head somewhere more private to talk about Sofi’s first-time experience of public masturbation. Despite her wonderfully brazen display, and how much she enjoyed it, Sofi still admits to feelings of shyness – however, she found this to be a turn-on, along with the risk and craziness, and she vows to repeat the experience. The pair say a fond farewell, with Sofi blowing kisses and, as she leaves the scene, the blonde is skipping – walking on air after her naughty thrill.
