Classmate Kokoharu, a quiet literary girl. Actually, it seems that he is doing a part-time job as a voice actor. "I'm going to be a voice actor for an erotic anime, so I want you to practice with me..." For her lack of sexual experience, the two of us read the erotic anime script full of dirty words and sex scenes. ……I was supposed to be in the role too much, and I was accused of being a slut by her who suddenly changed into a de nasty older sister! "I wonder if I can show this erect cock to my sister." Isn't it?" While getting drunk with the slut voice that dominates both ears, I actually practiced SEX with my cock.
