hello! Have been interested in erotic castration fantasy play. Really enjoy the idea of a pecking order. When I've tucked my testicles I've enjoyed that feeling/look as well. Thank you and glad to be here.

Welcome, I think you will find others interested in castration fantasy play and related activities. Perhaps many here started with that role play and progressed as time past going from fantasy to to being a eunuch. I can see the desire to tuck as a good way to explore the whole subject of castration.

This features searches the story ID tags, and not the body/text of the story.

I am a regular reader of the FA library, I always try to memorize the name of the author of the work I like.
