A nipple sensitivity survey conducted by the "Nipple Sensitivity Research Center," an institution that researches daily to treat women suffering from nipple insensitivity. This time, we closely follow the investigators of this facility and record the reality of a day's research. Using sensitivity measuring devices on the female treatment patients who come one after another, we record their body temperature, wetness, and number of orgasms. Many women have multiple orgasms on their nipples due to sensitivity enhancement treatment. A world of unknown nipple pleasure research.
