Christmas Payback (Patreon)

For aBigGuy

Remember few years back when Pharah and Mercy decided to prank Ana a bit with a Christmas sweater laced with some of Moira's TF juice?

Well it turns out the prank was a bit more of a permanent thing that anyone could have anticipated.
So far any attempts to revert the changes have been entirely futile.
Ana's humor regarding the situation ran out long time ago, so to encourage our lovely doctor to put a bit more effort into her research, (and to just get her back) she went and paid her back in turn.
