I Repeatedly Had Illicit Sex with My Sister’s Worthless Husband

Synopsis

My younger sister Reiko, who eloped, arrives with her husband. Though nervous meeting Reiko’s husband for the first time, I eagerly await their arrival. “Big sister!” Reiko throws herself at me in tears upon seeing my face. I think these are tears of joy from our reunion, but then she reveals that her husband’s infidelity has been discovered. The celebration mood instantly turns awkward as my husband and I greet the couple with tension in the air.
