SDJS-343 Male employees should try out the black pantyhose butt masturbator and submit improvements. SOD female employee new product development record - Akemi Iwagaya

At the suggestion of her boss, a female member of the development team is to have her male colleagues experience the appeal of a new product and gather their opinions. In order to not influence their opinions and to make a 120% appealing appeal of the new product without revealing who is wearing it, she is tied to a special desk and her black pantyhose-clad ass is fondled, rubbed, and enjoyed as much as they want, just like a sex slave.
