Trapped in a cramped closet, a devout brother and sister find solace in forbidden touch. The brother, his cock straining against his pants, watches as his sister, clad in a modest dress, can't resist the temptation to stroke his hardness through the fabric. Her breath hitches as she feels his length, her own panties growing damp. They whisper prayers of penance, yet their bodies betray them, grinding and rubbing against each other in the dim light.
