KSBJ-282 Tempted by my horny sister-in-law... Otonashi Tsukino

My younger brother's wife has a strong sexual desire. Every day I am at the mercy of my younger brother's tsundere wife who seduces me almost every day. As soon as my brother goes to work, he starts playing tricks on me. Sometimes they purposely show off masturbation, and other times they show off the activities of a married couple. And then it finally happened. We can't stand the repeated temptations anymore...and we cross a line that we shouldn't cross...
