Walking In On Cheating GF Becoming a Horse (Patreon)

Whelp, Christmas is ruined. You came home to see your girlfriend and some guy transforming into horses while fucking. They didn't even stop when you walked in. The worst part is that she knew you had a TF fetish and never once mentioned that she was a werehorse. 

Side note, does anyone remember betrayal-porn-gif-captions on tumblr? That was me lol.
