Kana Morisawa and her male coworker work in the customer complaints department. When his mistake provokes a vicious customer, she protects him and goes to the customer’s company to apologize in his place. There, the men demand that she kneel naked and humiliate her by forcing her to serve them, lick a customer’s filthy ass, and endure being passed around. Although it is all his fault, the sight leaves her coworker shamefully aroused and hard.
