Carleigh had just agreed with me that the level of her work thus far was not worthy of an A, and that she was willing to put in a little extra work to get one...
"So, then, I said to her, "I guess we have more work to do, don't you think?"
"I try not to, Sir; thinking gives me a headache."
I laughed at her clever joke, even funnier given the situation. "Yes, well. I believe I need to examine you very closely, and indeed give you an oral test to determine your level of understanding. Are you ready?"
"Yes, Sir, I am."
"Fine. Then sit here on my desk."
I pushed the papers aside I had been grading, such pedagogical tasks well beyond my concern any more, and Carleigh sat down on my desk with her legs spread wide.
Her pussy was the very image of perfection. Her pussy hair was completely shaven, something that has always turned me on immensely and made me want to dive right in to the pussy in question. The soft pink of her pouty pussy lips stood out in stark contrast to the white skin around it, and turned on as she was at this point, it glistened softly from her juices. She had a thick little clit that stood above the surrounded curves, almost beckoning me to lick and suck it. I approached her pussy slowly, not so much wanting to draw this out for her or tease her -- although I could hear her breathing becomes faster as I did and her body tense in delicious anticipation of the feeling -- but simply because I was so struck by the beauty the thing. I rubbed her clit gently, and she gasped, then I slowly traced the outline of her pussy lips with my fingers, gaping open mouthed at the perfection of her hot, wet cunt.
Being able to wait not one second more, I gently flicked my tongue across her clit, and she let out a long, low moan as I did so. Carleigh's pussy tasted delicious, making me want more and more. I sucked her entire clit into my mouth as I slowly slid first one finger, then two into her slick wet pussy; with my other hand I began stroking my cock, getting it hard quickly again. Carleigh was moaning loudly now, in time with the thrusts from my fingers.
She began to buck her hips hard and to moan even more loudly, so I switched things around a bit. I now began to lick the length of pussy, from clit to ass, stopping along the way to slide my tongue in and out giving her a nice tongue fuck, while I now used my fingers to rub her clit hard. This switch seemed to push her to an even higher level of ecstasy as she began to moan even louder and breathe in raspy little coughs.
My cock was now good and hard again, so I took my free and slide two fingers deep into her pussy, so I was now licking her cunt, finger fucking her, and massaging her clit. Her body began to tense rigidly and her moans turned into one long groan, indicating she would soon cum. I now began to lick, suck, rub, and fuck as hard as I could, looking forward to her finally exploding.
"I...I...I'm gonna...gonna...," she stuttered, sounding similar to the way she did when she first arrived, but now for a whole different reason. "Cum...cum...cum...."
Her body tensed one final time, and her legs locked around my head for a moment with such force that I feared for a moment that my eyeballs would pop out, then she let out what was a combined shriek and groan, like nothing I had ever heard before. Carleigh also let out a hot wet stream of pussy juice which squirted right into my face; at first I was surprised, but was instantly aroused by having a hot little squirter cumming right on my face, and happily opened my mouth to try to catch as my of the stream as I could.
Her glorious orgasm lasted for a few moments, and then she slowly began to slow down and relax, the once strong stream of pussy juice now dribbling down to a trickle. As she did, I methodically began to kiss and nibble my way up from her pussy, along her bronzed and toned stomach, to her firm white breasts, where I lingered to play with her hard nipples for a time. I then nibbled my way to her mouth, where we engaged in a deep, passionate kiss, out tongues dancing around each other's, swapping the remnants of our own cum.
"Now," I said, pulling away somewhat unwillingly from our kiss, "I believe your grade has risen to, shall we say, a B?"
"Yes, Sir, I'd say."
