NACR-743 I can’t take it anymore! My little devil of a niece, Mikoto Wakui, has been toying with me by teasing me.

My brother and his wife went abroad due to urgent work. While he was away, he was supposed to take care of her niece, Mito, but they were strangely close to each other, and as if to show off, he exposed his defenseless side. One day, she encounters Mito masturbating in the living room and finds out that she is peeking at him. However, it was a show-off temptation from my little devil niece!
