Trapped in a cramped room together, siblings find solace in mutual masturbation. The brother, his cock straining against his jeans, watches his sister's fingers dance over her clit. She's wet, her moans filling the room. Unable to resist, he frees his cock, stroking as she watches, her own pleasure mirroring his. Their rhythm syncs, breath hitches, and they come together, eyes filled with new, forbidden desires.
