You finish pleasuring Ms. Nanci

Right. You're down here to suck cock; better get to it. Clearing things up with Ashley will have to wait. In fact, the faster Ms. Nanci cums, the faster you should be able to catch up to your friend.

You begin alternating between lapping your tongue around Ms. Nanci's cockhead and sucking on it, and going up and down on her cock as deep as you can.

Ms. Nanci moans in approval. "Seems like you wisened up. Good boy."

After a while, your jaw is aching from all the excercise, and you take a break from fellating her cock to lick her balls and jerk her off instead. Ms. Nanci is happily whistling to herself all along, putting away some finished student assignments in the drawer next to you and stretching her back for a bit. She's pretty much ignoring you. For some reason, you feel like this hurts your pride. Your pride as a good cocksucker. Except sucking on cocks isn't something you would be taking pride in... is it?

Nevertheless, you feel you want her to pay attention to you, and put your lips around the head of her cock again, this time taking care to suck the hardest you can, while also fondling her balls. This should ellicit a response!

"Ooh!? That's the spirit! Keep going!" Ms. Nanci is finally looking at you, and you feel her balls rumble as they prepare to push their seed out of the urethra that you are currently lapping at with your tongue.

"I'm almost there, don't stop!" she's panting and lightly jerking her hips forward. Then she stops, and after half a second your mouth is flooded with her cum, coming out in thick ropes that seem to be several times longer than your own have ever been.

But there's so much cum! You have to swallow to prevent it from spilling out the sides of your mouth, but you're not fast enough. A few strands dribble out and down your chin. To keep it from landing on any clothes, you hold out your hands and gather it all up. Once Ms. Nanci is done and has removed her cock (with yet another wet "pop!"), you lick your hands clean and dry them on a handkerchief she lends you.

"Well! I'm impressed, Doug. Seems you had a hidden talent there." Ms. Nanci is clearly pleased with your performance. "That will be it for today." She rolls her chair back out of the way and you crawl out from under the desk, feeling a certain amount of pride.

"So... you'll fix my grade?" You lick your lips absentmindedly to gather up some stray stains of cum.

"Hold on now Doug. Like I said, you have a talent for this, and I feel that it needs to be explored further. If you do this for me every day for the rest of the semester, I should be able to gauge your true potential. Then I'll see about your grade."

Oh crap. Sucking Ms. Nanci's cock every day from now on?

"Uhm... I'll think about it." You mutter.

"You do that" Ms. Nanci smirks. "Now, shouldn't you go after that girl and try to patch things up?"

Ashley! You run out of the classroom to go after her, but it might be too late now.
