My nickname for a plain and weak guy is always "Doctor". But because of that, the girls in my class are wary of me, and they come to my house asking me to show them my adult videos. What's more, they get so excited by the sexy scenes that they stain their underwear, and when they can't help it, they ask for my dick, which is a perk of the job. This time, we're adding another person, so it's even better value.
