OFKU-166 Left alone with my wife's big-breasted, chubby mother...

This time, my beloved wife was hospitalized for childbirth and left the house empty, so for a while, I left my father-in-law at his parents' home and let my mother-in-law come to Tokyo alone. Therefore, our household began with just my mother-in-law and me, her son-in-law. The son-in-law pretends to help with chores and gradually gets closer to his mother-in-law… Meanwhile, the mother-in-law is also secretly excited about her young son-in-law.
