SPRD-1487 - City-dwelling mom gets ravished by her son

Momoka, who lived alone in the countryside, moves in with her son and his wife in the city. Excited at first, things take a dark turn when her son catches her masturbating due to her increasing libido. He forces himself upon her, ravishing her relentlessly. When her daughter-in-law later complains about her sexless marriage, Momoka is left confused and anxious, especially when she realizes her period has stopped.
