Gwenivis Power Hungry pg.? (Patreon)

As I said this is more of a future event thing that I just happened to do. Figured I should at least share this full image of it tho! Hope you guys enjoy. It was tough to get this well enough to the point I wanted. In case it's not clear Gwen is possessed by Mavis through a previous series of events.  I'll probably eventually upload this one publicly. Not sure when.
