“Sachiyo, Sachiyo, look at this!” he exclaimed. “I’m your son’s wife, Fuuka,” I reminded him. After my mother-in-law passed away, my father-in-law, now living alone, began to show signs of dementia, so we moved in together. He’d forget what he ate just moments ago, rummage through the fridge, or wander off at night. His condition worsened, and soon he started mistaking me for his late wife, subjecting me to excessive physical contact and borderline abusive behavior. My husband, busy with work, paid little attention, and our intimacy dwindled. One day, my father-in-law, in a bizarre moment, exposed himself completely. “You’ll catch a cold, please cover up,” I said, but I couldn’t help but gasp at the sight of his impressive size, and a tingling sensation began to stir within me. Then, the inevitable happened. He, as usual, mistook me for his wife and attacked. His sloppy kisses, relentless cunnilingus… his tongue skills left me soaking wet. And when his massive member thrust into me, I felt a pleasure I’d never known before, reaching depths I’d never experienced. I knew it was wrong, but I couldn’t resist his manhood. I’m sorry, I’ve crossed a line I can’t return from.
