It's almost the end of the year and I'm on track to be valedictorian!! Straight A's my whole life until missing 1 point on a physics quiz makes my grade an A-!!! So of course I talk to the teacher about giving me a little help but he's saying he'll only help if I make him cum?? I go to catholic school, I don't want to have sex before marriage, and I'm 18 so that teacher is way old and no way would I... ugh I need that A though. I reluctantly pop my DDs out of my uniform and wow my teacher's cock is huge, good thing he's not going to put it in me! Although apparenently showing and spreading my pussy wasn't quite enough so now he has me on all fours spreading open from behind and... his cock is grinding against my pussy? I need that A so grinding is ok but penetration isn't, although he's just cum all over my back and its dripping down my ass and he's saying "now I should be wet enough?!" Well, at least in the end I became valedictorian, even if I'm pregnant at graduation ♥️
