It has been almost a year since I married my husband, Satoshi, and lived at my in-laws' house. My father-in-law has been obsessed with his drone flying hobby since my mother-in-law passed away 5 years ago. My husband is quite meticulous, and my father-in-law is playful, which is quite different. That personality difference is also reflected in their nightlife. On the contrary, one is a very bland husband, and the other is a harsh father-in-law. The beginning of my unfaithful relationship with my father-in-law was when I witnessed myself masturbating because I was dissatisfied with my husband's performance.
