Sanada, a dull middle-aged man living alone, picked up a kitten three years ago. Since then, he has kept Karin as his pet cat... but the female cat's true identity is that of a Yandere monster cat who can't stop loving her kind owner... One day, when Sanada comes home smelling like a woman, Karin's flames of jealousy burn, and her love and lust run wild... The jealous female cat is in heat 24 hours a day! She milks her owner's sperm until her sexual desire dries up. "I love you so much, so please impregnate me with your child," the female cat's relentless forced mating causes the owner's reason to collapse!!
