You've been ogling the female students, and generally making a sexist nuisance of yourself! Fortunately, as your professor of Classical Civilisations, I'm equipped with an excellent way of dealing with you. Did you know that the Romans considered it extraordinarily shameful to fellate another man? The practice of irrumatio (energetic oral sex) was used to humiliate enemies, and I dare say they used it a lot. I think a little cock sucking would be just the thing to teach YOU a lesson, so I've bought a strapon, and I've got this wonderful ring-gag device too, for holding your mouth open while you're learning! It's based on a design found at a site in East Sussex, so I'm pretty sure this is exactly what the Romans did too. Now, open your mouth!
