This is a confidential report on the development of a new masturbator, conducted in the office on a weekday. Hikage Yoda (22) from the Human Resources Department was invited to serve as the vaginal model, and the test was thoroughly tested with 10 penises. From cervix monitoring to mass ejaculation checks and a threesome to report on the results, this is a complete record of the public pussy checks that were conducted calmly yet vividly as part of the job.
