A perverted female doctor conducts a so-called health checkup, subjecting female students to a nightmarish experience of nipple torment! She demonstrates various torture techniques—lightly pressing, sharply flicking, pinching, and pulling their nipples. She also uses her pointed tongue to tease and knead, driving them to ultimate pleasure. Specialized nipple torture tools appear, including measuring tapes, calipers, nipple suction devices, and low-frequency stimulators. Don't miss the intense nipple-to-nipple rubbing, or footjobs performed solely with nipples. Witness the girls lose control with ahegao expressions, climaxing in ecstasy and squirting—all from nipple stimulation alone!
