I’ll Teach You How To Cum Together

"No way… It feels so good… I never knew…" When she was young, Hina became conscious of the act of touching herself. One day, she went to the classroom for her first lecture at university, but no one was there. While waiting, her body begins to itch, so she puts her fingers in her pussy and starts to rub it. Just a little more, and she'll cum. She's so absorbed in the act when her teacher asks, "Can we start the lecture?" After seeing her obscene act, he kisses her deeply and says, "I'll help you do it till the end." The shlupping sounds are echoing in the classroom, and the teacher's fingers are moving faster…! If he keeps going, what will happen to me…!?
