About
A stranger on a train changes everything for a guy with a very specific muscle fetish, offering him the chance to help grow serious muscle on the women around him. The setup is goofy on purpose and doesn't pretend otherwise.
Before the train, life is flat: he lives with his stepmom Dorothy and stepsister Olivia, stuck in the same routine day after day. The woman's proposal cracks that routine open and points him toward something much stranger.
You play him as an ordinary guy in his 20s working an office job, and progress comes through a bit of grinding to reach the next stage of growth for the women in his life. The developer is upfront that Female Muscle Growth isn't in the game yet but is the whole point going forward, alongside planned height growth and breast expansion, with side helpings of femdom, maledom, and the usual body-type variety along the way.
