The super-erotic private tutor, Yuria-sensei, gives a lesson in seductive big breasts! She seduces a virgin boy who can't concentrate on his studies because he's too distracted by her cleavage, and gives him a breast lesson. When his grades improve, she gives him a breast-feeding handjob to clear his head, and as a final touch, she puts on an erotic costume and graduates from being a virgin, leaving both his head and his crotch feeling refreshed! Look forward to the skills of this talented private tutor, who will help you improve your grades and learn sex techniques!
