The blonde, as I understand it, is in the full care of the guy. So I do not see anything surprising about the fact that she meets him from work in an erotic outfit and with wet holes. More interested in the question - and on the stove, too, all ready, or just his dumplings prepared? Because he is such a man, he also wants to eat inadvertently.
A girl in glasses makes many people sexually aroused, there's something about it. And here, on top of everything else, she's also pretty and shapely, so the guy successfully hooked her up.
