Inran Uwaki Onna wo Netotte Nikubenki ni Shita Hanashi: Ki no Tsuyoi Gouman Hitozuma Manabe Kyouko

“I, Tatsunosuke Kayama, have a long‑standing “frenemy” friend named Kyouko Manabe. Although she’s married and values her relationship with her husband, she repeatedly cheats—her libido is insatiable, and she sleeps with other men.

One evening at our usual izakaya, Kyouko was complaining about her latest fling:
“Haha, so how about trying it with me just once?”
“Huh? What are you saying? Gross.”
“…I’m kidding, I’m kidding.”
“Ugh, stop with the bad jokes already. You low‑spec guy should be grateful I even listen to your whining!”
…Tha woman!

I’d secretly had my eye on Kyouko and even humored her petty conversations, never realizing how contemptuously she saw me.
In that moment, I made my decision: I would turn Kyōko into my own fucktoy.
