[UNCENSORED-LEAK] MTALL-133 Hinako Matsui disciplines the brat who mocks her for being a small dick with her 20.7cm big dick.

Synopsis

My nickname is "Deku no Bou" and I've been called that since I was a little big and slow. My younger brother has gotten older and is married and has a great family, but I'm unemployed now... I feel so pathetic and want to cry. One day, my younger brother and his wife went on a trip and I was asked to stay at home. At my brother's house, there is a damn cheeky niece, and the moment I met her, she called me "small fry and small fry" and tried to dominate me. I wonder if I can endure living alone with my niece for three days with this brat...
