Married woman Kaede secretly visits for anal training behind her husband's back. Her pink anus gapes open, greedily swallowing fingers deep inside, quivering uncontrollably. Her anal walls take an extremely thick cock, climaxing repeatedly through intense anal sex. Filled with enema fluid, she endures the agony of bowel movements before finally squirting a massive amount of liquid. Wearing pantyhose over her face, making grotesque expressions, and using a nose hook to pursue deeper masochistic pleasure, Kaede falls further into depravity as an anal threesome pushes her over the edge—a raw document of a married woman's descent.
