Soft-spoken, big-breasted office worker Asaka has a surprisingly dirty way of comforting a depressed coworker: she takes his cock straight into her mouth. When her coworker's father's boss makes a move on her, she pretends to be troubled but slowly sucks him too. Hoping to improve her sales results, she even asks him to teach her how to sleep her way to the top. Naughty Asaka eagerly seduces the boss, works his cock between her huge breasts, and finally lets him creampie her. With her sex skills sharpened, taking first place in sales should be easy.
