Getting into position

Amber watched as David bolted from class with great urgency, he just didn't seem like himself today.
The two were friends for a while, not in a romantic sense though.
They used to enjoy talking to each other and do their assignments together.
She knew him well enough to know that something was out of order and her curiosity steadily grew as the minutes passed by and David failed to make his return.

David was annoyed, horny and frustrated he as he crossed the hallway, looking for some privacy.
He will need a release, whatever it takes.
His eager cock seemed to be very much aware as she painfully grew in his jeans without any fear of getting caught.
David understood what was expected of him, basically a sign of good will that he was willing to meet her half way, she did say that he should at least *try* it.
After failing the attempt, she surely wont pass on the usual fun, David knew as much.
He planned to make appearance, a show.. to make her think that he tried his best but in the end he just couldn't reach, whether he was able to fully perform it or not - will forever remain a mystery.
With that plan in mind he went into a service room, knowing it should be a safe place considering the students are in classes at the moment and the janitor isn't working today
As soon as David opened his first button, the zipper pushed all the way down as his cock burst to freedom "FUCKING FINALLY!!"
She throbbed happily, leaking pre and feeling rock hard more than ever before.
He rolled his eyes as he got rid of his jeans, "Ok.. we will try it just this once.. but then you will cum in whatever means if it doesn't work.. right?"
"Yes!" She promised, unable to contain he excitement.
"Shh, not so loud!" he urged her, as he began his show, sitting down and attempting to reach her.
"Uhh, David? sweety.. what are you doing?" she seemed confused and so was David.

It was completely against her nature.
From the moment she came to be and was aware of herself, she could only think about a single thing - pleasure!
To deny herself such pleasure just to get her way with David for a future benefit, wasn't a trivial thing for a sentient cock.
Her evolution was rapid, her primal instincts were mixed with fantasies, plans, thoughts and feelings.
She was far more intelligent than what David wanted to believe she could be, considering the body part she was.
And that was exactly what she was counting on, to be underestimated.
Surely, she wouldn't leave her fantasy to fate or David's hands, the same 'hands' she wanted so much to avoid from.
She had hours to plan that moment, and she couldn't contain her excitement when her plan went on course as David came to terms with trying her idea, whatever that meant for him.
And so, when she was finally freed and saw David making his move, it was time to take action.
He was puzzled, but she didn't leave him like that for long - "It wont work like that, here.. let me get us into position".
The shock on his face was priceless as she pushed his bottom half against the wall, until she was right on top of him with his legs hanging across his head.
Now she had full control and gravity on her side.. it was finally going to happen!
