[Hitotsukami (Kitamura Kouichi)] Cruel Revenge [Kawaki]

Sayaka's classmates think they know her — until a vengeful spirit seizes her body and marches it to the front of the classroom, where it pee into a bucket and defecates on a desk before the stunned, wide-eyed class. Just as the shame reaches its peak, the possessor is violently expelled from her mouth, leaving the real girl gasping in a room now steeped in her own public disgrace. But the revenge isn't done with her yet: a relentless anal assault follows that leaves her crying, cumming, and rolling her eyes back in an ahegao wreck of sweat and tears.
