I Didn't Know That My Wife Got A Creampie Every Day For Half-A-Year From An Underworld Guy. Iroha Natsume

My encounter with that man began when I took over my younger brother's debt. The man took a liking to me at first sight and pressured me, saying, "Become my woman." He raped me as I kept refusing... Since that day, he has been having his way with me without missing a single day.
