I'm going to share TF stories that I've enjoyed a lot. (Yes, I'm copying Mr. Cavanaugh)
Tyler and Josh: An Age Swap Story is a great M2M age swap story by Tservo96. It's an age/life/role swap between a junior high school principal and a 13 year old boy and I was amazed because it's quite similar to one of my earliest fantasies. If you love a TF that features a suited man, don't waste your time and start reading it now.
