Chronivac booted up.
"Battery at 65%..." First Ryan upped his own muscle definition and stamina a bit. He flexed his arm and looked pleased at the resulting bulging bicep. He then thought about Bryan and decided to help him out a little. He increased Bryan's cock size to 7 inches while flaccid and 10 inches hard but kept it fairly thin. He then made Bryan only a meagre 5 feet tall and made him a bit younger in actual age and appearance. He wondered what Bryan would think about this change. Would it be positive for him or negative? He was already on the short side but wanted a bigger dick. Now he got one in exchange for being shorter. He made it so that everyone remembered Bryan as this but Bryan and Ryan would remember everything. Ryan remembered the girl from lunch all of a sudden getting all interested with his penis. He took his appandage out and looked at it with a grin on his face he lifted the throbbing tube of flesh and decided to make it even bigger. 13 was an unlucky number so it had to be 14, nothing too massive a difference at his already enormous size. He chose to not get any thicker, it was already more than a handful to get off. He looked at it and smirked as it lengthened. He shut off Chronivac and chose to get off before the next class his new length proving enthralling. The bell rang only a moment after he shot his first load. He had to run for to not be late. His penis in its still slightly swollen state wasn't particularly helpful but he made it.
Ryan made a note for Bryan and left it in his locker. He however didn't state his name but only gave a link to a private chatroom with the text below it. "It was me who did it. ~Master of Change" Before school was over he met Bryan again. Looking in quite high spirits. Ryan innocently hailed him and asked what was up. "It grew." Bryan said blushing a little. Ryan frowned. "Really?" Bryan nodded. "Well you were above average to start with." Bryan looked confused. "Everyone that's seen it before keeps saying that." Ryan smiled. "Well, it's true, especially for a kid your age." Bryan opened his mouth and shut it without speaking a word. "I noticed that I look younger too but everybody says that I don't, I feel shorter too but everyone says I was always this short." Ryan laughed quite quietly. "Well, you probably were smaller in the best, but as long as I've known you you've been this size." Ryan bend over. "But what I got from this is that you believe you got a bigger penis in exchange for becoming younger and smaller." Bryan hesitated. "Well, yes, I know it sounds weird." Ryan leaned back. "Well, I figure you don't find this a bad change." Bryan shrugged. "I'd give more years of my life for a bigger dick."Bryan laughed. "Well, then I guess it's fine in the end, a bit weird but fine." Bryan also laughed and then walked off. Well that was surprisingly successful.
Bryan at home closed to door to the bathroom while breathing heavily. He grabbed it and started rubbing it in his privacy. "Fuck yes, bigger..." He said over and over as it got hard. Rubbing it in one hand then with two his breathing further intensified. Even as it was fully hard he he kept saying. "Bigger, harder... come on... " He rubbed it more violently. "Fuck yes, harder..." His 10 inch hard-on shot out a good stream of cum and then another before going soft. Bryan looked at his improved package and looked quite pleased as he started fondling it again. Bryan always wanted a big dick. He mostly watched porn where the male stars where massively endowed and after seeing Ryan's soft 12 inch cock this feeling only intensified. Now he had a big dick for himself. Still remembering Ryan's cock left him envious looking at his still swollen but flaccid penis that only hung tot about 8 inches or so. He shook his head but conceded to himself that he would have loved for it to be even bigger perhaps even if he had to look younger still.
