[ENG Ver.] Now Commencing The Nipple Sensitivity Examination

No sexual penetration. It's all on the nipples!

As it turns out, the part-time job that college student Shiori Otokawa applied for was a gig for participating in nipple sensitivity examinations!?

* What is a nipple sensitivity examination?
The national agency known as "Nipple Pleasure Laboratories" is conducting research into female pleasure, and they want to perform a series of examinations on the sensitivity of womens' nipples.
Seeking applications from: Ordinary women (providing daily wages)
Testing method: Using sensitivity measuring devices to record subjects' body temperature, level of wetness, number of orgasms, and other parameters. Examinations are carried out in 3 sets of 10 minutes each with a 1 hour break between each set.
The first set measures "sensitivity from teasing," in which the examiner stimulates the nipples indirectly and through clothing in order to gauge the examinee's response to the stimulation.
The second set measures "clothed sensitivity," in which the examiner applies aggressive stimulation through clothing. During this set, the examiner also applies lotion and gauges resulting changes in sensitivity.
The third set measures "orgasmic sensitivity," in which the examinee is disrobed from the waist up and the examiner applies stimulation with the goal of triggering an orgasm. In the case of an examinee with particularly favorable sensitivity, the examiner will use various techniques to trigger consecutive orgasms and record the examinee's response.
