[Limited collaboration between Maiyuki Ito and Premium for one adult drama!] A female teacher, Mayuki, kindly invites a student who is soaked while preparing for the school festival to her house, but her boyfriend can't come home because of work, so she ends up spending the night alone with the student... The student is turned on by Mayuki's true face, which she shows out of loneliness, and her exquisite body, which is inappropriate for a teacher, and crosses the line! Even though she has a boyfriend, Mayuki's breasts and Kokoro shake every time she is penetrated deep inside by a violent piston. At night and in the morning, she is made to cum many times by the insatiable student...!
