Crammed into the closet, siblings Michelle and her brother struggle with religious guilt. As their father commands them not to move, they're haunted by lust. Michelle's baby brother's massive cock tents his pants, drawing Michelle's eyes. She tentatively touches it, feeling its hardness. They start to rub, Michelle's tight virgin pussy getting wetter. They struggle to maintain control, but their innate desire takes over. They fall into a passionate, forbidden sex act, their bodies pressing together, juices mixing, until they collapse in post-coital remorse.
