Muscle warm-up studies, featuring patron OCs! (Patreon)

Thank you to everyone who lent me their OCs for this!!

These characters belong to CapricornDemon, Truhalo, WickedestCape, Bigby, Matt Lion, Lars, and SkittyBitty!
I might still do more of these in the future by picking from the submissions in the form, just... I need a little break after all this muscle work :P
