A nipple sensitivity survey conducted by the Nipple Sensitivity Research Center, an institution that conducts daily research to treat women suffering from nipple frigidity. This time, we closely followed the investigators of this facility and recorded the actual situation of the day's research. A sensitivity meter is used to record body temperature, wetness, and the number of orgasms for women who come to treat one after another. Many women have continuous orgasms with their nipples due to sensitivity improvement treatment. The unknown world of nipple pleasure research.
