I knew I was going to have trouble with you - unfortunately, some young men find it hard to take my 'Penetrating and Being Penetrated' social science class seriously, and only join in the hopes of finding hot girls to fuck. Fortunately, I know exactly how to handle boys like you! Dressed in my sensible tweed skirt and sweater, I explain how getting you down on your hands and knees, naked, with a cock gag strapped into your mouth and a fucking machine drilling a dildo repeatedly into your ass, is going to teach you a valuable lesson, and serve as useful research for me. For example, I can see that this treatment is turning you on; your (rather small and disappointing) cock is rock hard, isn't it?  And if that wasn't enough, I can see that you're actively sucking on the big dildo in your mouth, and rocking backwards and forwards on the dildo impaling your ass. Perhaps it's time for an even bigger dildo? I think so! And how about if I hooked a fucking machine up in front of you so that you could suck on a thrusting dildo at the same time as being fucked in the ass? I think that would be just the thing. And all in the name of science!
