That was not its intention. Its intention proved quite different. Mr Derais seemed, again, to have his eye on her and she paid mock attention, staring in his general direction. It was then that she felt the pen touch her foot. Mandy tried to push it away as if it was a troublesome insect: but that did not work. She could feel it on her calf, felt it climbing to her knee and then, to her consternation, felt it slip under her skirt. It slid up her inner thigh where her skin was so soft and sensitive. What was it doing there? It then came to her, a dreadful certainty about what the pen intended to do and there was nothing she could do to stop it. She was unable to pull her thighs together and clamp them shut around her sex.
It could not really be happening. Pens did not move by themselves, panties did not slide down by themselves, one did not feel invisible hands pulling open one's thighs - not in a physics lesson. Not anywhere. Mandy had a terrific urge to get up and run from the lesson but she did not dare. Not from Mr Derais' lesson. He frightened her and she did not dare. She felt rooted to the spot. And then she felt the pressure on her shoulders holding her down.
Mandy had thought, several times before, that Mr Derais's thick Parker pen had something of the penis about it, It was rounded, bulbous and, she had joked with her friends, he clasped it in his hand just like they thought he would his penis. They could not imagine Mr Derais having sex with anyone but himself. What woman would have him?
The pen had slowed its progress, its movement upwards had become a snail's pace but it had not stopped, it was still progressing, very slowly, up her thigh. It seemed Mr Derais' eyes were focused on Mandy as the tip of the pen touched her; she did not dare move or take her eyes from his; she tried to concentrate on what he was saying but it was very difficult as, beneath her skirt, one end of the fountain pen - the cap or the rounded base - was slowly pushing itself into her like a thin, smooth, hard erection. It was not difficult for it. The earlier feelings had seen to that. Mandy knew she was wet, could feel she was wet. She hoped her skirt would not show it.
She gripped the sides of her desk and stared intently at Mr Derais but she could not even make out what he was saying. The pen, Mr Derais' fountain pen, was almost completely within her. Approximately six inches long so there was room. Had not boys pushed their erections into her that far? Had she not played with the handle of her hairbrush which was about that length? It would fit. Perhaps, she hoped, it would cease its movement and just rest there, like a rabbit in its burrow, so perhaps, just perhaps, she could sneak it back into Mr Derais' desk at the end of class.
But no, the pen did not cease its movement. It began to move just like her boyfriends' penises had done. In and out, in and out, backwards and forwards. At least there was no risk, Mandy thought, of ejaculation. The movement was persistent as if a hand was moving it and it was a movement that did nothing to lessen her arousal. In, out, in, out.
There was a pause, a withdrawal of the pen from her.
Mandy was sure a flush had appeared on her cheeks but with everyone concentrating on Mr Derais is would not be noticed. What might have been noticed, had anyone been looking at her or her desk, was the appearance of the pen - or rather the cap of the pen coming up over the side of her desk and settling itself right in front of her. Her eyes spotted the movement, spotted it creeping across her desk and spotted that it did not simply have its usual glossy appearance but possessed a positive sheen - a sheen of wetness. Her eyes jerked up again, not simply out of worry about what Mr Derais might say of her inattention but the sudden feeling of the returning pen, very clearly minus its cap. Was it re-entering with the bulbous end uppermost or, worryingly, with the sharp nib pointing upwards? Why had the cap come off! She braced herself for the sharp pricking sensation of a gold nib catching her in a most intimate place. But none came. Nonetheless she could feel it easing into her.
Her relaxation was premature as, all of a sudden, she felt deep within her a squirting, an ejaculation no less. Something she was not exactly unused to. For a moment she was puzzled and then it came to her - Mr Derais' fountain pen was doing just what it could do and expelling its ink, the turquoise blue ink Mr Derais wrote with, right inside her. The nib was indeed uppermost inside her and squirting ink - or rather, and she knew this to be the exactly what was implied by the action - ejaculating ink into her vagina. Spurt, spurt, spurt.
Slowly the pen withdrew and, after a moment, it appeared over the top of her desk, the discharge, the ejaculation of the turquoise ink showing wetly around the upper barrel. It too crept across the desk and slowly inserted itself, almost sexually, into the top and clicked tight and rotated until it was firmly attached and then all was still.
The strange activity seemed to have ended: but there was Mr Derais' pen sitting on her desk right in front of her, her panties were in Mr Derais' desk and, worst of all, Mandy had the awful feeling the ink was dripping from her and making a turquoise blue patch on her skirt.
Picasso had a blue period and, now, so did she.
