Muscle Growth in "Super Sized Vengeance Plus"

[Matador]

Winter Warning has a new comic up in the Process store that features prominent muscle growth. The cool bonus is art from Kalibann from the first try at the comic that was never finished. His painting style art is one of my favorites.
There's weight gain as well, which I like, but the comic is equally split among the two fetishes. I'm more partial to the weight gain, but the muscle growth is icing on the cake.
