[STARS-706] I just wanted to stay for my wife's sister who missed the last train... The stress that accumulated without sex exploded, and I played myself to commit until the morning. Kudo Yura (Censored)

Yura graduated from university and got a job at a company. I happened to think that my sister's house was nearby, so I called her and asked her to stay. But ... My sister and her husband are working together and seem to be busy recently and are sexless. Husband is in a state of frustration ... lust for Yura's defenseless appearance. I attacked my wife without asking questions.
