Haruka came to her husband's parents' house where his father-in-law, Toru, lives alone, ahead of his husband's overseas assignment next week. At such an important time, Haruka learned of her husband's affair and couldn't trust not only her husband but also a man. However, only my father-in-law, Toru, was special. I loved him as a man. I have only one week left to stay with my father-in-law. Haruka straddles her sleeping father-in-law, and when she gently overlaps her lips, she rubs her crotch and boldly exposes her feelings and lust.
