Stop him and try to get away with just a blow job after all

As Goodage begins to slowly push his cock into your anus you suddenly reach around and grab his shaft.

"Wait!" you say stopping him from entering you ass, "I can't do it, let me suck you off instead."

You start to turn around but your old teacher pushes you back to the desk, "Damnit you silly bitch I've been after you ass for years and I'm not gonna be put off by a fucking blow job this time!"

"Not my ass please," you beg, still holding his hard cock.

Mr Goodage hesitates in thought a moment, "Your cunt then."

"Okay," you relent, guiding him to your other hole. He lets out a deep groan as he thrusts forward, burying his erection deep in the clutching warmth of your pussy.

"Oh yeah, this'll do just nicely," he breathes as he starts to pump against your butt, his hard cock sliding rapidly in and out of your cunt. Goodage grips your hips tightly and pounds into you hard and fast. There's definently no finesse to his fucking, he just wants to blow his load and isn't looking to get you off too.

After a few minutes of ruthlessly using your cunt his breathing starts to quicken, "Oh here it comes bitch!" he almost squeals as he shoots heavily up inside you. Goodage moans and his face contorts as he gives a few hard bucks into you, milking the last of his cum into your pussy.

Once he is spent he pulls out and wipes his dick on the smooth cheek of your ass. You gasp in surprise as he pushes his thumb deep into your asshole, "Pity," he sighs wistfully.

Well he ends up giving you a B+ which is better than nothing. Time to hit your next class and hopefully score better.
