The sister-in-law was caught masturbating by her brother-in-law
My wife has a very beautiful younger sister who just came up from the countryside. She has a curvaceous body, big breasts, and firm buttocks. I was captivated from the first time I met her. Perhaps Takanashi still doesn't have a boyfriend because during my time here, I have unintentionally witnessed her masturbating multiple times. Despite being married, faced with such a youthful body, I couldn't help but feel sexual desire. While she was masturbating, I barged in and caught her in the act, then threatened her to indulge me or else I would tell others about this. Despite being scared and knowing that it goes against moral principles, she agreed immediately due to the threat and being in a state of arousal.
