Nothing productive got done after he said goodbye to a still withdrawn and thoughtful Katie; he spent the evening staring at the watch or miserably fondling his barely-there cock and balls. What if the time ran out and it still didn't do anything? He'd be left as a virtual eunuch for the rest of his life! He stroked his infantile equipment until it achieved its 'full' length, just a hair below one inch long. There was no shaft to speak of, just a small pink head and tiny, apparently undescended testicles.
Finally, the clock reached eleven and he grabbed at the watch, which he'd had the presence of mind to buy before the mall shut, thumbing the Settings option. '1.0 inches', it read. Finger trembling, he hit the '^' arrow until it reached his normal size. His finger, whether by accident or on purpose, lingered on the up arrow just a moment longer and he watched as the display went from 5.4 inches to 5.5. He stopped for a moment. If he pressed 'Adjust' now he'd be slightly bigger than normal. Why not go decisively larger? Heck, he might even have a chance with Katie.
So he continued thumbing it, thinking about all the average penis size surveys he'd read about. When he'd passed the 5 inch mark as a 13 year old he'd been relieved - the sex education textbooks at school said that was the standard erect size for an adult male. He was already average, and surely well on the way to 'big' at such a young age. But then he started finding other figures. Online, he read the average was 5.5, 6, 6.5... A friend told him that it was definitely 7 inches. He had started feeling decidedly under-endowed, even after what he suspected was his adult size at 5.4 inches. He decided that he wouldn't let that happen again.
He watched the number on the screen go past 6 inches, past 6 and a half, past 7... he finally took his finger off just before it reached 7 and a half. That had to be big enough ... for the next twenty-four hours anyway. He pressed 'ADJUST'.
This time the feeling was distinctly different - an almost erotic warmth spreading throughout his groin, like an erection but far deeper. He slid down his shorts and boxers and watched - his cock was already out of micropenis territory and accelerating, new shaft growth carrying the swelling head further and further from his body. His balls grew heavier, rounder, and settled back into their familiar place. He was merely 'mediocre' now. Then 'average'. For a moment his hand registered the familiar shape and heft of the penis he handled every time he went to the bathroom or jerked off. Then it started feeling unfamiliar again, the shaft becoming plumper and thicker in his hand, the head elongating with a wider coronal ridge tapering down to a meaty slit. He cupped his balls, feeling them hang fuller and heavier by the moment.
When it was done he opened his closet door and admired the result in the full-length mirror - his slim hips and relatively sparse pubic hair made his now distinctly above-average erection look even bigger; a thick, juicy organ a good two inches thick at the centre. Concentrating, he allowed his erection to subside, and watched it contract, finally settling at a good five inches soft. He was almost as big flaccid as he had been erect! Let's see Katie complain about this, he thought.
