Okay, I have been away from E for awhile, and am looking to get back in some RPs here. Here are some of my ideas, in order of preference.
1) Drider or Drow. My character went on a raid into the Underdark, which went badly. Attempting to get out, he was caught by a drider, who makes him her slave. Or, a drow is raiding the surface world for slaves, and catches him unawares.
2) Gor. I am not looking for a strictly by the book Gor here. More like the feel of the world. Several ideas here.
2a) Counter Gor. Here, the women are the dominants, and males ofter made slaves. A female Warrior captures a male, and makes him her slave. Maybe he tried to steal from her, and was caught, or she saves his life, or takes him on a raid. Or buys the new slave from a passing slave caravan.
2b) Panther Girls. He was hunting in woods claimed by the Panther Girls. Getting caught in one of their traps, and made their slave.
2c) Silk Slave. Their is a small market on Gor selling males as pleasure slaves for high born Free Women. Perhaps an Earth born male, or someone young made into a male silk slave.
3) Succubus. He was trying to summon a succubus, but should have paid more attention to his penmanship on drawing the containment circle. Or, she seduces him into becoming her slave.
4) Making a pony In a post-apocalypse, a woman, highly trained in martial arts, human pressure points, seduction, is looking for someone to pull her cart about. And she finds and captures my character to be her pony.
If any of these interest you, let me know. Am fine with males playing females. And Herms and Futas would be okay.
