      NEWS: Discord Server & Clubs (aka Groups) are back!   08/19/17

      Hello everyone I'm back with a couple big updates! Firstly we now have a Discord server, this is a real-time chat messaging client you can run on your phone, desktop, or anywhere. It's a pretty powerful desktop application that enables people to chat together, and with multiple channels you can find people interested in what you're interested in. If you don't already have a Discord account it's pretty easy to get one, just click the following invite link to get started: https://discord.gg/Ahzu9jC Secondly I'm proud to announce the return of Groups, it's been renamed to Clubs and is now available here: https://muscle-growth.org/clubs/. This system is entirely user generated and allows users to create groups of their own based on any subject they want. Go ahead and try it now, visit the link above to get started if you want to create or join a group!   As always thank you to all of our donators and Patreon contributors who keep the forums going!

Machine influenced muscle growth(/age progession?)


I'm looking for a muscle growth story. In it a pair of boys transform into muscular guys using an invention by the other's father. The second boy comes into a basement where the invention is by the first boy's invitation. The second boy is dressed into bigger gym(?) clothes. The first boy is already transformed(?). The transformations are based on porn pics from the net. They have relations in the end.


I'm generally interested in stories of this theme.

I have a blurry memory of the story you describe, but I can't recollect its name. I hope someone else does.

As for other stories of this theme, one of my short stories belong to that particular category, but the protagonists in my story are probably about ten years older than the protagonists in the story you ask about.


All my army-themed stories use machines too, but constitute a sub-genre of their own.
