I came from the same direction but I think that I originally came to read enema stories. I have enjoyed the site so much I've even taken a shot at writing one. It's not as easy as you think!
Me, too, almost, but definitely not as easy as you might think. Having some kind of sexy or arousing thoughts you'd like to do or try doesn't mean you automatically know how to write a coherent enjoyable sexy description of it. I've had a longstanding particularly involved fantasy that I've written posts about several times. It's about what an enema enthusiast woman might experience as she starts going to a colonic practitioner for the first time. She finds she loves them so much that she almost becomes addicted to her colonics and her orgasms afterward at home. So she asks if her colonics can be escalated to make them longer and larger and more frequent, even if she has to pay more.
Well, since it's my fantasy brain working, of course they give her what she wants eventually, gradually getting larger and longer more intense colonics. But of course since I have several other kinks, they get worked into her treatments, making them kinkier and more challenging and intense and erotic as she goes. And of course she discovers she loves the kinks they add to her treatments. Since her colonics get larger and longer, eventually she winds up being required to wear special "protective" rubber clothing and shoes in case she has a leaking accident during her very long huge colonics. Finally she reaches sort of an ultimate logical conclusion to her desires and my fantasy, convincing the staff to incorporate orgasms into her colonics (which the staff rationalizes as the ultimate way to shake up and thus clean her colon, adding orgasm spasms to her full belly). She becomes a very satisfied multi-repeat customer..............
Like I said, I've written a few posts describing parts of this but never put it into a complete story. Hopefully I'll get inspired to flesh it out into something I can post as a blog or long story. Obviously, I'd love to be the "patient"/client's partner and watch her go through it, or even better, just become the patient myself!
