Sachiko, Sachiko, look at this! "I'm your son's wife, Fuuka." After the passing of my mother-in-law, my father-in-law, who has started to show signs of dementia, has moved in with us. He forgets things like the meal we just ate and opens the refrigerator, wanders around at night, and his condition has progressed significantly. Eventually, he mistakes me for my mother-in-law and his excessive touching and borderline harassment become unbearable. My husband is too busy with work to pay attention, and our intimate life has completely disappeared. One day, my father-in-law jokingly exposes his lower half! "Close it, you'll catch a cold," I say, but I can't help but be captivated by his impressive large penis. My private parts start to ache. And then, the dreaded thing happens. My father-in-law mistakes me for my mother-in-law and attacks me. His tongue-licking kisses, persistent cunnilingus... my vagina becomes dripping wet. The large penis penetrates my vagina, providing an unprecedented pleasure. It reaches my previously untouched G-spot. Even though I know it's wrong, I can't help but accept my father-in-law's penis. I'm sorry, I can't go back now.
