"Yeah. Try as I might, writing this into reality may be a fant-"

Mineta had begun, but was digressed from his thought be a strange feeling in his exposed penal region, which was accompanied by a hard thud on the carpeted ground.

Mineta didn't even look down; he knew full-well what he'd find. He could feel it. It... It was...

"N-n-no way!" Mineta gulped.

Finally working up the courage to look down and, sure enough, his half-erect penis was now just as long as he was... if not, longer. It had fallen to the ground and kept snaking under the desk. It had seemingly changed into being more equestrian, as well, which didn't help matters.

"OH!!! OH MY GOD!!!" Mineta cried out, in a mix of bewilderment, panic and a touch of excitement.
