Goshujin-sama wa, Otou-san ~Tsuma ni wa Ienai Himitsu no Yuugi~

...It seems I won't be able to fall asleep right away tonight. I could pretend to be asleep, but it's a husband's job to satisfy his sexual frustration. I should satisfy my adorable, sexually frustrated wife. "H...n!? Ngh! Mmm!" My wife's reaction was different from usual, so I pushed my erect penis into her, rubbing against her lukewarm flesh. The truth is, although I'd found sex with Chise satisfying, I'd never been satisfied. That's because I had my ex-wife, Kumi. We were madly in love with each other, and I loved Kumi so much that the thought of cheating never even crossed my mind. I had planned to spend the rest of my life with Kumi. But— A few years ago, Kumi was in an accident... "Ah... It's alright, husband... The pain is subsiding... You can do more." "Pain...?" The muttering I heard sent chills down my spine. "But Dad... after you remarried, you only had eyes for that person... You've always been concerned about me. Am I really that much of a nuisance?" I gasp. There, there was a girl named Hazumi, Kumi's daughter who was like a mirror image of Kumi.
