Hina and I started dating when Hina was a student. Because we were in a student-teacher relationship, I maintained my chastity no matter how much Hina wanted me to. Today is her graduation ceremony. Finally, the day has come when I can respond to her feelings. When I took off her uniform, I was surprised to see her big breasts... I lost myself in the feelings I had been holding back until now and the big breasts in front of me, and I passionately fucked my girlfriend Hina again and again... A drama that depicts a forbidden relationship that is a mixture of immorality and intensity.
