Greediness is a bad thing

You know what the price for that A is and you're not ready to pay it. Jenkins sees your hesitation and, deciding that he's already gotten what he wanted from you he gives a couple of powerfull jerks through your tits, making his swelling dick climax. You feel the warm sticky goo splashing against your underchin as his ejaculation takes you by complete surprise. The cum starts dripping from your chin onto your tits as his dick start to soften, smearing your belly with more cum.

You are sitting in a total mess infront of your professor's desk wondering how you'll manage to clean everything up as Jenkins handles you your blouse.

"I'll be keeping your bra as a souvenir" he tells you, to make things worse.

"It's a pity you didn't want that A, I'm sure you could excell if you wanted to" he says, showing a sign of disappointment.

"I'm sure I would but a B is quite fine" you reply as you try to clean up yourself with a spare piece of paper you've found on the desk. You quickly make your way out of the office, feeling quite uncomfortable wearing just your blouse . At least a B can secure you a decent career in the future you reassure yourself. Even though the opportunities that could come with an A never stop comming to your head for days to come.
