A poor female student with a vague sense of loneliness comes out of a certain apartment complex. She is approached by a trashy old man who also lives in the complex, and in order to help with the family finances and to pay for her living expenses, she gives up the romance of being a woman and engages in prostitution, just like an angel. She takes advantage of the angel's kindness and lets him cum inside her like a demon. That's what we, trashy old men, are like.
