She pouts at him, playfully. She's already horny and it's only going to get worse.
Fuck if it isn't hot that he can just, choose to do this to her. Leave her horny and a mess and barely enough time to get ready for class when he leaves, since she still hasn't gotten Art History squared away. Yet. She's going to look horrible when she shows up (well, comparatively of course. She still looks hotter than the rest of the girls in this school on their best day even on her worst. But it's the principle of the thing, you know?), and she probably is going to need to get in a quick orgasm just to get this out of her system enough to concentrate on seducing Billy (or was it Bobby? Doesn't matter) into doing all her homework in class for her. Fuck if she gets left this horny she might actually fuck him. That would certainly get him to do her work, for the rest of the semester, at least. Normally she tries to do it without even touching them, because they're not really worth touching her, but fuck if she's this horny then she'll take whatever she can get.
He did mention he wants her worked up before the next time he uses her. Maybe she can do it to herself?
Fuck she's so fucking horny right now. Needy and aroused and he's doing that thing where he teases her as she gets close and then he stops and she wants to cum so badly. Fuck. Fuck. She knows he said he'd leave her like this, but she's pretty sure he'd still get off on hearing her begging. And, well, she really wants to cum. It's not like she can easily stop herself from begging at this point, she's already moaning "please" over and over again. She should get some good begging in, before it gets even harder to think and that's the only thing she can say, fuck, fuck, FUCK. That feels so good fuck.
"Please, please, please sir, please, I want to cum so badly sir, please, pretty please, let me cum, this feels so fucking good sir please don't stop don't stop don't st... no please, fuck, I want it so badly, sir, I want you so badly sir, I belong to you, you own me, control me, possess me, but I want to cum so badly so please let your pretty possession cum for you please sir yes just like that please please PLEASe no please, fuck, sir, please."
