HUNTB-402 "Licking the teacher's fingers gets me excited." The rational mind of a home tutor like me collapses under the melting finger blowjob from an usually docile teenage schoolgirl! "I want you to teach me how to lick it."

A female student seriously asked me to teach her how to lick. I thought, 'This is really bad,' and made up various excuses to brush her off, resulting in using finger-fucking to get through the situation. However, the girl was abnormally sensitive to finger-fucking and was too erotic! Just looking at her erotic lips made my erection unstoppable! Before I knew it, I had her suck my dick and I ejaculated a massive load! The pleasure was so intense that my rationality began to crumble…!? In the end, I did it with her.
