Our school is proud of its special health and physical education classes. The teacher for the third and fourth periods is the idol-like Momo Shiraishi. Her vaginal diameter is 3.92cm. She's perfect as a teaching material, but she's still a rookie. When she's penetrated by a man's penis and her nipples are played with, she can't help but make strange noises. She couldn't even support his erection properly, and was scolded by her senior in front of the students - do your best, Ms. Shiraishi! But it's always the cute student's dick that shows the way to the troubled teacher. "Mr. Shiraishi, you like being choked, don't you?" His secret sexual fetish is revealed, and he is moved to tears by the growth of his student, who has a convulsive orgasm. Mr. Shiraishi even says "Please cum deep inside me!" and gets plenty of creampies. Let's learn together with the student and cum!
