I'm doing my best trying to get you to focus on your homework, but you really seem to be struggling here. Finally, when I'm getting up to grab a snack, I catch you staring at my ass. It's so obvious that you're not learning anything so let's just handle this now and then maybe you will focus properly. I tease you with my big boobs and encourage you to suck on my nipples. You finally let it slip that you have a fetish for assholes. Naturally, I need to shove my ass in your face and tell you that you need to stroke for my perfect little asshole. I tell you to get your face deep up in there and have you lick it and tease my pussy with your tongue until you make me cum. Now that that's out of the way, are you going to actually focus on your homework? Good. I just know that you are going to get such good grades now.

You'll never look at assholes the same way again!
