Simon cried out with pain as the needle jabbed into him, and when it withdrew, but he then felt amazing warmth spreading rapidly from his arm to the rest of his body, and he relaxed and in seconds lost consciousness.
The jocks made a circle around the unconscious geek, knowing what might happen, but hardly daring to believe that it would. Mark stepped forward to remove the constraints, which they knew would be unnecessary if all went according to plan.
Then, to their excitement, things started to happen as they had been lead to believe, but so tentatively, had barely imagined to be possible*. Simon’s body gave a shudder, and began to expand. His chest swelled, until his pectorals were two masses of muscle. His neck swelled to the thickness of a tree trunk, at this point thicker than his head, although in due course it would be the same width. His lats flared out behind his shoulders, which were now like boulders above his arms. His arms thickened, and the biceps were far beyond the typical male’s, in fact great cannonballs of power. His waist formed a 32” V, underneath a six pack on which, as the saying goes, you could grate carrots. His thighs were pulsing, cylinders of strength, and his calves bulged out almost quivering with energy.
All this was enough to make a total jock. But this was only the beginning. Once the changes to the muscles of the body were in place, an even greater change began to kick in. Simon’s skin began to darken, starting from the crotch, and spreading all over, becoming a dark, glistening, chocolate, bronze color. Only the hands and the soles of his feet retained a pink coloring, but much darker than before, palms of his His bald head visibly became squarer, and his brow contracted, while his cheek bones became far more prominent. His eyebrows became sexy commas above his eyes, angled outwards and his eyes became deeply hooded, and almond shaped, slightly tilted upwards and outwards.
His nose broadened and his nostrils flared outwards, while his lips became far fuller than would be possible for a white man, filling his lower face and giving a promise of unspeakable sensuality which would never go with such a hard and virile face and body in the case of a mere Caucasian.
His prick at this stage remained the same as before the transformation. Nevertheless, the jocks were awestruck by the transformation that they had experienced.
Simon began to stir. Mark knowing that there was a limited time to change his mind and personality, knelt down beside the Afro Adonis that Simon had become to whisper in his ear.
* Yup, the author of this passage has been reading Henry James. It messes up the subordinate clauses like fuck.
