APNS-173 Female college student who handles sexual needs at the cafeteria Yuisei Yui

In that warehouse, stragglers recruited from the yakuza were forced to work hard. The male workers are being worn down day by day, physically and mentally, reaching their limits... One day, Yui, a part-time delivery worker, came from a super-discount home delivery lunch shop that comes once every three days. The men who had continued the woman drought lay down Yui and do as much shame as possible. Since then, Yui's heart has been eroded and degraded as a tool for sexual processing. Eventually, the yakuza who are in charge of the place also appear.
