Fair warning for Face Falsa and The Adventures of a Lonely Witch. Just because they are age regression stories doesn’t mean that they are best to read while regressed. Face Falsa only has background agere anyways, and Lonely Witch is dark af, mostly because of the mental health issues the main character faces.
If you want a better story to read while regressed, I recommend my FredxCedricxReader, it’s just wholesome agere one shots :))
