It is the appearance of Oneshota planning new series! Mr. Maceo who came to play in the winter vacation at the house where relatives' big sisters live. At first, Masegaki Maseo had a quiet face and was wearing a cat. I am very excited about the huge breasts of my relatives, Yu and Kurumi. After all, my older sister Yu is a B110 (J cup) and my younger sister Kurumi is a 98 (I cup) buddy! ! Maceo, who wanted to see the two of them naked by all means, played tricks on the sisters with big breasts while looking sideways at Kazuya who lived in the neighborhood who happened to come to play! ! Maceo uses his privilege as a child to trick his adult sister into various sexual harassment attempts. Please stay tuned!
