BF-691 — While My Wife Was At Her Parents' House, I Had Sex With My Student For 24 Hours Straight. Nana Kisaki

After a fight, my wife went back to her parents' house. While she was away, my student Nana came to my house. She said, "From today, I'll be your wife," and took the place of my wife, even though I didn't ask her to. But I never expected her to even have sex with me.
