In the secret language of their shared culture, a sister and brother find solace in the forbidden. She masturbates "rico," indulging in the rich textures of her own body, her fingers exploring every curve and crevice with a hunger that's almost religious in its intensity. He listens, his own body reacting to her every moan, his hand working his cock in time with her rhythm. They're both lost in their own worlds, yet connected by the taboo that binds them, their bodies pulsing with a lust that's as ancient as their shared heritage.
