GVG-031 Anal Stand-In Wife: Mitsuki An Steps In

With no money for the alimony she owes, Mitsuki An agrees to fill in for a woman killed at a level crossing. The dead woman had been faithful to anal sex, so Mitsuki takes over that part of the marriage. She goes through enemas, a plug, a vibrator in the bath, and the rest of the routine, and finds her body responding more as the days pass.
