In the dim light of their shared bedroom, siblings Maria and Joseph, raised strictly in the faith, find themselves drawn together by an unspoken, taboo desire. Maria, her eyes wide with innocent lust, tentatively reaches out to touch Joseph's firm chest. He responds, his heart pounding, by cupping her small, perky breasts through her thin nightgown. Their breaths grow ragged as they explore each other's untouched bodies, guided only by primal instinct and the dim glow of their bedside lamp. They remain clothed, their virtue intact, yet their bodies betray them, wet and throbbing with forbidden longing.
