For anyone who loved Boring Days especially, you may find this findom erotica story to your liking:

There are several scenes in it that reminded me of both Belinda's and the maid's route, and in general it's great fap material if you're into findom!
If you do try it out just bear in mind that it's a 17 chapters story and you should probably stick with it for at least 2 or 3 chapters before you decide whether you like it or not. (the first chapter mostly just sets the stage and is a little dry and boring) Cheers!
Warning: There will be a few elements of NTR and mild maledom in the 6th and 7th chapter! (the Mistress of the male protagonist goes on a night out and has vanilla sex with a guy that "takes charge" - the sex isn't shown but she teases MC about it, compares him to the "jock", and the guy also appears the next morning and has about a dozen lines) This story has long chapters (the longer ones are over 10k words), and the maledom seems to be a one-off event (at least by the 11th chapter which I'm currently on), so there's overwhelmingly more femdom content (most of it findom, very strict chastity, humiliation and enslavement of MC, with a little bit of CBT, Caning and foot massaging in some chapters) than there is vanilla/maledom, but that scene did disgust me quite a bit (I mostly skipped through it and kept reading the rest of the story as the writing quality is much better than for most online erotica) and it most certainly was not femdom, so I thought it irresponsible of me to leave this post unamended! If you don't think that would disgust you, it is a good findom story, but otherwise stay away!
