Kobayashi, her subordinate, is always scolded by Waka, who is good at her job but has an overbearing personality. When he tries to call a delivery health service to complain about his girlfriend, he finds a place called ``acquaintance delivery health service'' where acquaintances come, and when he calls, the person who comes is Waka. She suspects that she is some kind of prank, but although her attitude is bullish, she gives a slutty blowjob as a delivery health girl while saying dirty talk and being obnoxious. She ends up cumming just like that.
