The daughter-in-law of a brother with a strong libido. Every day I am at the mercy of my tsundere younger brother's wife who seduces me every day. As soon as my younger brother went to work, he started playing tricks on me. Sometimes, I show off my masturbation on purpose, and sometimes I show off my husband's work. And finally things happened. She sneaks in when I'm trying to sleep...and we have a line we shouldn't cross...
