[Takeuchi Reona, Koiwa Eta] sleep rape [MTL]

A dark-skinned older sister and her bespectacled younger brother are plunged into a nightmarish spiral after a forbidden cream pie leaves them insatiable, driving them to violate their sleeping younger sister and niece in increasingly depraved group acts. Sweat-drenched bodies tangle in rough anal and double penetration as the victims moan in their sleep, the story climaxing in a messy bukkake finale that leaves the perpetrators' guilt and arousal in uneasy, irreconcilable balance.
