The hemp rope digs into my flesh and I am dyed with sweet pleasure, and my uncle's hideous penis stirs up my young flower core!! A sweet punishment turns a beautiful girl in uniform into a sex slave...I'm a naughty girl, so please punish me... Summer vacation... I'm staying at my uncle's house to attend a cram school. By chance, I find a magazine with a woman tied up. I unconsciously masturbate using the rope. My uncle finds out and "punishes" me.
