In the tight quarters of a closet, siblings succumb to forbidden lust, their religious constraints shattered by the heat of their bodies. As they squeeze together, half-clothed, the brother's massive cock tents his pants, drawing the sister's gaze. She tentatively reaches out, wrapping her hand around his shaft, feeling its throb. He gasps, pushing his hips forward, and she tentatively begins to stroke. Their movements are tentative at first, but soon they're lost in the rhythm, the sister's hand moving faster, her breath coming in short gasps.
