Eimi-san, my sister-in-law, who is very cold to me and beautiful but a bit weak. One day while I was watching AV, she suddenly came into my room (sweating). And for some reason, I decided to watch AV together without going out! That night, 'Responsible for not being able to sleep (Teru)' crossed the boundary with my sister-in-law in Japan, and a luxurious secret life began! The situation of living together without my brother-in-law!
