Mutant Mass (Muscle Growth Animation)
FINALLY, our second Muscle Growth Animation is here!
This one is based on the voting that we did on our Patreon, special shoutout to our Gold Patron, Raz for the story idea!
Just another day at the gym for our guy here, except when someone snuck a little boost just for, you know...a little help ;)
We're also going to release the extended cut version next month, so stay tuned!
