I say hopefully because I know pregnancy, impregnation, oviposition, lactation, insemination, etc don't appeal to everybody, and these ideas are too good to lose potential partner who don't like it.
1. Pokemon role reversal. I read this in another thread sometime within the last month, so if you're reading this, stand up and be credited! In an alternate pokemon universe (or not), humans are the possessions of their pokemon masters. They're the primary vessel for breeding pokemon (and much more fun), they're pitted in nonviolent or violent battles against each other, and more. I don't have any special ideas for this, but rather an alternate one. A pokemon trainer (in a regular human being the masters setup) has the tables turned on her by either an opposing trainer, a spiteful gym leader, team rocket, or perhaps it was her pokemon themselves who decided to rape her and become her master. My only need on either of these ideas is that i'm playing the human female.
2. orcs and elves. Since I'm pretty much a one trick pony, I figure I would put out feelers for this again. I want to play a female elf. She could be a noble princess, a celibate paladin, or a simple farmers daughter. Somehow, she ends up in the hands of an orc or orcs. Possible kinks are slavery, degradation, humiliation, ownership symbols like piercings and tattoos, shamanic brainwashing/taming, impregnation, bondage, multiple penetration, bestiality even. Looking for a dom who knows exactly what he or she.wants.
If you're interested in either of these, pm me or post here.
