In my experience, it’s not the dumb girls who are easiest to take advantage of. It’s the smart, ambitious ones.
They want to badly to get good grades, to get a good letter of recommendation, whatever it is they need their trusted teacher to do for them. I always offer to speak with them after school when they want to ask what they can do for better grades, to make sure their academic career goes as well as possible.
It takes some pushing and probing, especially with the virgins, but the ones who really want the boost give it up. Their tight little cunts and their sweet moans compare to nothing else. I always fuck them raw too. If they get pregnant, that’s their issue and not mine.
I always keep my promises, though. Any one of those brainy little sluts that gave up their pussy always advances more than any of those that didn’t.
