I think it's about time I made one of these.
I'm a bit of an odd cookie with the way I roleplay, I guess. I tend to think more in terms of the concept, rather than a plot, scene, or role I'd like to play out. But that just leaves more wiggle room for my partners to help me build something awesome!
I'm not gender specific for any of these ideas, but I will be honest I've been craving some good MxF interaction lately, but these could all very easily be anything else.
I greatly enjoy stories about people coming out of their "boxes," for lack of a better way to put it, and discovering the world is bigger and more mysterious than they originally thought. Some concepts I'd like to explore further would be:
Dharma Bums TAKEN!This would be set in the sixties (easily one of my favorite time periods), and would explore the mentality of that era and the "free love" movement. There would be drug use and philosophical debate. Either I or a potential partner would (theoretically) play a newcomer to the movement. The newcomer would get the full treatment, which would include a full sexual awakening. Again I would love to see more added to this idea.
Arabian NightsSo, I like sociology, and one of my favorite subjects is sex over time and how different cultures' historical attitudes towards it have changed, and a great way to learn about that is to look at pornography over time.

Back in the Victorian era a very common porn story was that a good English (or German, French, Spanish) girl is kidnapped and whisked away to an Arabian harem where she is draped in finery and "deflowered" by a dashing Arabian prince. She usually resists at first but he coaxes her into it and she finds she likes it (a lot), and then resists her countrymen's attempts to rescue her. I've always found it to be a really neat look into the Victorian mindset and I'd love to explore
God Is In The RainThis is one of my particular favorite concepts for a story. I base the concept loosely on the work of Charles de Lint, who works with the idea that the world is bigger and more mysterious than most of us think, and that if we look closely we'll find the things we didn't think exists. Another good example of this kind of story is Neverwhere. Very good show. Anyway, this concept would center again on a newcomer being introduced to a modern fantasy world by a more experienced character. I would love to flesh this out further.
So that's what I have for now. I'll add more as it occurs to me. If interested, check my O/O's and send me a message!

Thanks for reading!
