I write fanfiction under the penname Iron Dog and post them here and to adultfanfiction and mediaminer.org. I write in a variety of fandoms and everything can be found in The Smut Repository. I do both het (male/female pairings) and yaoi (male/male pairings), although the bulk of my writing is currently yaoi.
Be advised that almost all fiction I write is NC-17. There is also a healthy (or unhealthy depending on your views) dose of kink of all kinds. If you're easily offended, then this isn't the place for you to be. Don't say you weren't warned.
As a rule, I don't friend back immediately. No slight is intended by that.
