I Only Meant to Let My Sister-in-Law Stay Over After She Missed the Last Train... But the Stress from Our Sexless Marriage Exploded and I Fucked Her Endlessly Until Morning. Yura Kudo
After graduating from college, Yura started working at a company and got carried away at her first office drinking party, missing the last train. Remembering her sister's house was nearby, she called and asked to stay the night. However, her sister and brother-in-law were both busy with work and had been in a sexless marriage lately. The husband, in particular, was pent-up with frustration and became intensely aroused by Yura's defenseless appearance. Without hesitation and careful not to alert his wife, he forcibly took her. That night, a new shift began to unfold in the couple's relationship.
