Rowena to use some form of lust spell on Dean for a fun night? Can be exchanged for Ruby, Meg or any other evil bitch from the Supernatural series.
Up for some real het as well with Jo, Ellen, Lisa Braeden, Charlie, Amara, Mary Winchester, Anna Milton, Pamela Barnes, Tessa or Billie the Reapers....or maybe some fun little crossover with The Good Place!
