I've been writing erotica for several years now, mostly with a Dominant/submissive theme, and have published an erotic-romance novel as well as two collections of my shorter erotic fiction. You can find more of my writing here:

I also occasionally train female submissives online. If interested, see below:
----------------------------------------------
You are an intelligent, independent woman... but you fantasize about being controlled by a complete stranger. Being used for his pleasure. Having to perform humiliating tasks for his entertainment. Obeying him in all ways and begging him to punish you for your slightest mistake. I'm a WM in my early 50's. If you're looking for someone to explore your submission fantasies with online I am experienced and patient. First-timers are welcome--feel free to ask any questions you may have.

You do not need to be drop-dead gorgeous or have a perfect body but I do ask that you be in reasonably good physical condition--I'm sorry, but no big girls please.
If what you find in my stories appeals to you please feel free to contact me via the link above.
