March 4th 2045 (Day Four)
Tyler didn't notice anything unusual over that weekend. He woke up and inspected his junk. It looked normal, his flaccid length a measly 2 or so inches. He queried Siri as to whether anything was happening.
"The nanobots are still in the multiplication stage Tyler. You will have to wait at least another 60 hours for the process to be complete. In the meantime sexual function may be impaired."
"What?" Tyler asked. If it had been out loud, the statement might have been shouted.
"The capacity for erections has been curtailed for the time being. I assure you, full functionality will be restored later. I am preparing eggs for you downstairs to assist in the process."
"Alright, whatever" Tyler said, throwing off the blankets to get on with his day.
Monday also passed without incident. It was a typical day at Woodgrove High. Tyler had Maths and Chinese in the morning (his third language) followed by double coding after lunch. He made no mention of Siri's mysterious offer the previous Friday night. Checking the newscasts, the headlines were the usual ('Lagos Crisis Continues: 12 US Soldiers Killed in Ambush', 'Hurricane Selma Headed for London', 'SpaceX Callisto Mission Soon to Make Landfall').
Arriving home, still alone, he headed up for his bedroom.
"How we doing Siri?"
"The process is nearing completion, full functionality has been restored."
Tyler stripped off, his slim form standing in front of the mirror on his desk. Inspecting his flacid junk, he did notice it seemed a little larger. He gave it a gentle rub.
Immediately he felt a tingling sensation. In a few moments it seemed to race up his spine to the back of his neck. He suddenly felt extremely horny, greater even than three days without jerking off could explain.
"Jesus!" he said out loud. "What was that?"
"New bodily structures tend to possess heightened sensitivity."
"So this thing is good to go then?"
"Indeed, give it a go Tyler."
Tyler was already rubbing his dick up and down, each stroke feeling ten times better than he ever remembered it feeling before. He almost fell down before reaching the bed, so intense were the sensations. In another minute or so he could confirm it absolutely - he had never seen his dick anywhere near this huge.
At that point it looked angry and pink. Laying his hand along the top he could barely cover it wrist to fingertip, and wrapping his hand around its girth his fingers barely touched. For a moment he had the disorienting sensation that his hands had shrunk dramatically instead, but no, this was quite real.
A sudden thought occurred to him. Ignoring the pleasant sensations, he jumped up and rummaged frantically through his room for a ruler.
"Try the third draw, Tyler" Siri suggested without prompting. Tyler so, pulling out a 30cm plastic ruler he might have had since kindergarten. He pressed it along the top of his erect dick, pressing it gently but firmly into the pubic bone, as was supposedly the proper measuring procedure.
17cm.
Tyler couldn't believe it. It had probably been some months since he had measured, but his 'regular' dick had never passed 12cm. He had grown...what was it? Two inches in the past three days?
"Jesus" he whispered. He inspected his engorged member carefully. It was perhaps a shade pinker, but that was apparently the case with newly built skin and veins. He queried Siri again.
"Nothing wrong with it?"
"Full sexual functionality has been restored. Urinary functionality was never interrupted."
