Haunted by religious guilt, the sisters clutch at each other in the darkness, their bodies burning with untouched desires. Michelle, the elder, gently pushes her younger sister's hand against her brother's crotch, feeling the thickness of his cock through his pants. They gasp, their hearts pounding as they slowly unzip his fly, revealing his massive, virgin cock. They fall into a feverish rhythm, licking and enveloping the shaft, their tight, untouched vaginas rubbing along the hardness, soaking it with their lubrication. As they fuck each other with their mouths, they're consumed by a mix of shame, lust, and pleasure, praying for absolution even as they chase their orgasms.
