Fics like Oliver and Miss Lily: Locktober Shenanigans

A little story about a trans boy in chastity and his loving domme. This is purely self insert personal fantasy filth lmao. Includes a master/pet dynamic, medical kink, bondage, catheters, bladder control and mild humiliation. Check the tags as I might add more if I continue this. I'm attempting Locktober so I've been locked in my belt for most of the past 5 days, what I'm saying is I need an outlet. This is my first time posting here! Oliver is a trans man who's on testosterone and has had top surgery. He uses masculine terms to refer to his clit but is comfortable with the words 'pussy' and 'cunt' to refer to his vagina. Lily could be read as cis or trans, I haven't decided yet lol. Disclaimer: I have never had a catheter inserted myself, so that scene was based on me reading about the procedure. This is just a fantasy of mine so there are probably many inaccuracies.
