YSN-333 Ah, I want to get my sister-in-law completely pregnant… My sister-in-law who is smaller than me, Tsugumi Serizawa.

The smallness of the body that can be seen from the appearance. Her brother-in-law teased him, saying, "You're a little kid," but his sister-in-law herself was surprisingly comfortable with the karakai. I always wanted a younger brother, but I thought it would be impossible because of his parents' discord. It became a reality, and having a younger brother, which was a dream, made my brother-in-law feel cute and allowed anything, which later caused his brother-in-law to run away. A brutal brother-in-law's forbidden impregnation play targeting a small sister-in-law! !
