When I was studying in the library after school, I was 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, she's breathing on me, and she keeps showing me her panties! 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...
