You can see everything through the magic mirror! A group of perverted doctors tinker with the immature body of a young girl in the prime of her youth! A private company is working with schools to conduct a developmental status survey. This time, the targets are the headstrong dance club member Kana and the demure Hana, who aspires to be a chef. Seeing her friend's areola being kneaded and manipulated by the doctor, Kana gets mad and asks, "You're a professional, can't you be more gentle!?" But their sweet bond is no use in stopping the abnormal adult. With their delicate mucous membranes dug and every orifice peeked into, the beautiful girls are slowly brought to heat. They take huge dicks' massive creampies in their tight pussies over and over again, and squirt in ecstasy while screaming. Study hard!
