Gif: EXPECTO BIMBO! (Patreon)

Mordred was a notorious bully at the magic academy, but after he lost a wizard's duel the boys all knew him as Mildred, a girl who only cared about a different kind of magic...

Fun fact: The bearded guy in the "before" part of this gif is actually the same guy you can see on the far left, just over the shoulder of the fellow with the wand! This was some porn gif set at Hogwarts, and before anybody asks, I don't know the source! In the original the guys just magicked up a horny girl out of nothing, there was no TG element, and I took one of the wizard dudes from a separate shot and turned him into Mildred.

Looking back now I see that there have been enough naughty wizard and witch gifs lately that I could have branded this month Magical May! Of course, there was also plenty of magic in April, and there will be more in June...
