To keep quiet, aiming for better grades, with their favorite teacher, etc. The close-knit group of J○ girls tempts their homeroom teacher! Even though they try to stop the girls, they are shocked when their nipples are teased! When they get an erection, they are served by three of them in a row with 'right nipple → penis → left nipple'! Even during handjobs, blowjobs, and sex... The sensitive nipples are constantly stimulated with pleasure! The homeroom teacher is completely manipulated by the 9 female students.
