I remember reading a story a while back that I enjoyed at the time, but I haven’t been able to find it since. It was a futa frozen fanfic, and the premise was that something happened and Anna grew a dick and it was increasing her body temp so she went to Elsa for help. I thought I read it on literotica, but I might be wrong since I haven’t found it on there since.
