Living with my wife Kyoko and her mother. I'm constantly terrified of my domineering wife. Meals are meager—sure, my income is low, so it's understandable, but she never allows me sex either. My mother-in-law, unable to stand up to her daughter, treats me gently and with consideration. One afternoon while Kyoko is out, I reluctantly masturbate with a porn magazine and get caught by my mother-in-law. Apologetically blaming her daughter, she tells me she'll take care of me in her daughter's place. Gradually, she begins kissing me. Her clinging, moist lips feel sweet, and I find myself falling deeper into our affair. A strange relationship blossoms amid daily life, portraying tender intimacy with my mother-in-law. This story reveals the complex emotions that emerge beyond the boundaries of family.
