A lady who cleans the corridor of the apartment every time she passes by. At first glance, she looks like an ordinary middle-aged woman, but if she suddenly shows a shyness because she doesn't get along with her husband, she will seduce a man with a vulgar kiss. As it is, the aunt goes up to the man's house who has been watered down with a kiss and tastes the man's body disgustingly to the bone marrow.
