Just think of standing in front of a class full of 18 year old school girls, bored senseless and crazy for adventure. It's kinda a sensitive issue, but have you ever pondered what it would be love to be a teacher in an all-girl college? You've been careful for years now, stayed away from improper eye contact and steered clear of their personal space.
Of course, this doesn't mean you haven't been thinking about it. The sweetest schoolgirls know very well how easily they can play men like a game of pool - and who better to experiment on than their schoolteacher? It's a nice opportunity for them to broaden their manipulation skills. They can go full throttle all day long!
So they do things like winking at the lecturer and arriving in short skirts. You have students who start competing with their girlfriends and decide to up the ante. Which leads to increasingly ravishing surprises, like suddenly find yourself staring at totally naked young twat when turning to address the classroom. Surely gets the blood pumping. Believe it or not, there isn't a professor, professor, teacher or tutor anywhere in the world who hasn't been in this situation.
All this horseplay and joking aside though, quite a bit of the school girls effectively do get infatuated with their lecturers. Their skimpy dresses and unexpected skin contact near the school entrance are simply the onset. They'll stop at nothing to get them to lower their guard and fuck them silly. They will have their lucky instructor panting for seconds by the time they're finished. The old fart hardly had a chance. That's to say, assuming he even chose to forgo all the fun to start with, of course. Hell, they'll request a private training session, grab his penis just like that and fuck him as hard as humanly possible!
