Bunnie only has one chance to pass her freshman final and when the volunteer doesn't show up she realizes she has to experiment on herself. The lab she was assigned to tests a new "vaginal sensitivity formula" for women who can't get turned on. As the subject of the experiment, she performs a variety of tests including using a rectal thermometer, taking measurements, getting an inside sample, and testing current sensitivity. After that she applies the formula and massages it outside her cute college pussy and squirts some inside and it drips out like a creampie. After waiting 45 mins for the formula to develop Bunnie turns the camera back on and she's turned from embarrassed to lewd and horny. The formula made her pussy swell up and did increase the sensitivity A LOT. She performs the external (hitatchi) and internal (dildo) sensitivity tests and of course both make her cum. She realizes she's obsessed with the formula and begs her professor to give her some if he enjoyed the video ♥️
