A sweaty middle-aged man is taken to his home and is insidious and perverted, and is trained to kiss his tongue

Single, no money, can't work. I'm such a disliked person by the world. One day, there was a girl standing alone in the park for lunch. Hearing his story, he apparently ran away from school and got into a fight with his parents and ran away from home. At first I was honestly worried and invited him home. However, I lost my rationality because of her so cuteness and defenselessness, and before I knew it, I had been licking and fucking her... After that, I couldn't stop myself from stopping, but eventually my girlfriend started asking for sex.
