Model and actress-turned-director Sandra Shine is back with a sizzling-hot new <em>Undercover</em> adventure. At Lake Balaton in Hungary, she meets Zafira – a gorgeous, brown-eyed brunette showing off her curves in a floral bikini. It’s a very hot, sunny day and Zafira explains that she loves to cool off and party by the lake. She also talks about her girlfriend, who was too busy to join her this time around, and admits she is missing her and bored without her. Clearly in the mood to confess, Zafira reveals that she’s seen people have sex in and on the lake, and she’d love to try it in a boat. Her girlfriend is aware of this fantasy but is shy, prefers sex in bed and is reluctant to try it in new places, especially out “in nature”. However, seeing hot guys and girls at the lake is making Zafira horny today, so she asks Sandra to film her acting on her “dirty ideas”. Giggling, she suggests they rent a large water-bicycle and, after a false start – which sees Zafira jumping into the lake – they pedal it away from the shore so the crowds can’t see what they’re doing. Once Zafira is happy with their location, she puts on a show for the camera, directed by Sandra. She pulls down her bikini top to display her full breasts, licking her fingertips and tracing them around her nipples. Next, she rubs herself through her bikini bottoms, before pulling them tight up into her slit. Her pussy is shaved, with a little landing strip of pubic hair on her mound. She fingers herself, splaying her lips and teasing her clit before plunging two fingers inside. Pausing, she tells Sandra that pleasuring herself on the water feels exactly how she imagined it would. Moaning and sighing she continues, legs so wide apart she’s almost doing a split. As she gets closer to orgasm, grinding her fingers on her clit, her moans become more urgent until she finally cums. Sandra suggests a dip to cool off but when Zafira emerges she is still not fully satisfied. Pulling her wet bikini bottoms aside she fingers her slit, and teases a nipple with her free hand. In what seems like no time at all she begins to orgasm again, and Sandra captures the horny look on her face, followed by a close-up of her cum-swollen pussy. Sandra also informs her that her little show was watched by other people on the lake, but the two agree it’s “all part of the game”. Zafira is happy and looking forward to showing her girlfriend the movie. She admits that her lover is likely to be jealous at the sight of her having solo fun, but reassures her on film that they will have sex together when they both return to the lake. And Zafira is hoping it will be on a water bicycle! The movie ends with more chat before Zafira relaxes, enjoying the sunshine…
