My daughter-in-law's mother who came back to Tokyo from Matsumoto ... Mio Morishita

Mio Morishita, the mother-in-law, comes to Tokyo to help her daughter-in-law with her second childbirth. She finds herself in a situation where she is tempted by her son-in-law, who takes advantage of his wife's absence. As they spend more time together, he engages in a creampie act with her, taking on the role of the seducer. The central kink revolves around the taboo of an affair between a mother-in-law and her son-in-law, adding an element of complexity to their familial relationship.
