A favour for a favour

It doesn’t take you long to decide how to answer the girl's question, but you decide to play with her a bit, and see how long it takes her before she realises your true intentions.

“Well Jess, you are pretty close to the upper borderline for the grade, all I need is a favour for the favour i'm going to do for you.”

With that you begin to loosen your tie, looking the girl up and down.

The girl seems pretty quick on the uptake, obviously this isn’t the first time she has been given this sort of offer.

“Oh, I think I know what sort of favour I could do for you, maybe you could help me see how much fun it can be in the classroom.”

With that she begins to press herself up against your body, one of her hands on your chest, the other slowly running down your body towards the growing bulge in your trousers.

You reach your hands around her body and grab her arse, pulling her tight into you, and begin to rub your crotch into her.

The girl pulls away slightly before dropping down onto her knees between your legs, and starts to fumble with your belt.

You help the girl undo your belt and then lift up your hips to allow her to easily remove your trousers. The girl then pulls down your boxers to reveal your hard cock.

With lusty abandon the girl leans forwards and instantly deepthroats your cock, pushing it hard into her warm and wet mouth. You feel the back of the girl's throat as she takes your cock deep into her mouth.

Pulling her head up a bit the girl begins to suck you, using her mouth on the end of your dick, and her hand on the bottom. She bobs her head up and down on your penis like a professional, and the thought races though your head again, this is not the first time she has done this for grades.

You sit back and continue to enjoy the blowjob you are receiving from this girl, and look down at her body. Looking down from her bobbing head, down her back to her rounded arse you decide that you want a piece of that.

You grab her shoulders and lift her from her work. Standing her up you turn her and push her face down over one of the desks. Reaching underneath the rim of the top of her jeans you give them a mighty tug downwards, pulling the jeans and her underwear off.

With one hand you push her legs wider, and with the other you lift it to her glistening pussylips and begin to stroke them. Standing up straight you slip two fingers inside of her, and pump them in and out whilst stroking your cock.

Pulling your fingers out of her well lubed hole you line up your cock, and begin to push it into her. You feel her soft outer lips spread to welcome your cock, and you slide into her to the tighter ring just inside. With a bit of extra **** you push yourself into her, spreading her tight pussy open to allow for your cock to penetrate deep into her.

You begin to fuck her, your cock moving in and out of her slippery, wet insides, her tight pussy clenching around your cock.

After a short while of this you feel the cum welling up through your groin, and pull yourself out of her. You grab her shoulders and spin her around and push her down to the floor, before pushing your cock back into her mouth just in time for her to catch your cum.

You spurt jet after jet of cum deep into her throat, feeling her swallow the salty ejaculate before pulling your softening cock out of her mouth.
You begin to rearrange your clothing as the girl before you does the same.

“Well I think that deserves a grade raise, thank you for coming to see me with the problem Jess.”

With that the girl smiles happily and leaves the room, probably heading to a bathroom to clean herself up.

With the girl gone you dispel all the spells, and arrange the teacher so that he will think he has just fallen asleep. You also leave a ‘remind me’ note from himself so that he doesn’t forget to raise the girls grade, well she was a great fuck.

Now then, what could you do next, there is still some of your free left.
