Crossover ageplay with Spencer Reid and Anthony Dinozzo
There was a fanfiction story where both Dinozzo and Reid were into ageplay but not by choice. Reid was in a wheelchair but learning to walk. He had been in some type of accident. Hotch was his caretaker. Reid and Dinozzo meet in a daycare. I remember at some point they snuck out of the daycare to go to the movies.
