Rica, a girl haunted by religious guilt, finds herself in a twisted, taboo situation. In the dim light of their closet, she and her brother, Cokis, press together for warmth. Rica's eyes are drawn to the massive bulge in Cokis' pants, her pussy aching with a lust she's never felt before. She tells herself it's wrong, sinful, but her body betrays her. She reaches out, tentatively, her fingers brushing against the hard length of his cock. Cokis gasps, his body tensing, and Rica knows she's opened a door there's no turning back from.
