GS-038 After school, I was doing some research in the empty library when the most seductive female teacher in the school came over to do some sex, and we were left alone...

While I was studying in the library after school, I found myself alone with the most seductive female teacher in the school...! She seems to be teaching me, but I can't concentrate because she's so close to me, blowing on me, and flashing her panties one after another! She's so seductive that I can't stop getting an erection! I'm in agony from the teacher's erotic techniques! I want to cum, but she won't let me!? Erotic sounds echo in the quiet library...
