Intro. Helena is your very sexy young wife. You're both at the beach and you have to leave for a while because she asked you to bring her sunglasses that she left at the car. On the way back, a muscular guy shamelessly took your place and flirted with her without her seeming to be offended. He's stuck to her and your wife's hand is in his shorts, in his crotch area...
