I'm a homeroom teacher who's in a slump in my relationship with my wife, and my student Walnut seduces me by saying "let's play cheating," so we meet up at a love hotel after school. I know it's wrong for a teacher and a student, but we cross the line and have sex without a condom. She has an immature body and a cute smile. I keep giving in to Kurumi's Walnut, who gets more and more lewd and wants me to cum inside her... It's just like adolescent sex. I may not be a good teacher, but I can't stop playing cheating and I end up cumming inside her sensitive pussy again and again.
