I was watching "Criminal Minds" and got a sudden idea for a role play, and depending on the characters, it might get pretty"intense."
I was thinking of having an RP in which A psychopath kidnaps a boy at a very young age from a mall. The boy could have been no older than eight-years-old at the time, and would never have been more impressionable. When the Psychopath takes the kid "home" the home comes to be a very secluded place in the middle of the temperate forest. SOMETHING has been done to where the boy does not, or is not able to, leave the house. (Again, depending on the Psychopath's character, and the level of maturity here) After several years, the boy is hitting puberty and is freaking out as his kidnapper starts to notice. The boy believes he's going to be kicked out because he's looking different, and is scared, over the years he has grown used to the cruelty of his kidnapper and is now fond of him. The kidnapper in turn is as well fond of the boy, even if he does treat him like a slave.
Some things could be changed in according to your tastes, and my edits. I was hoping this roleplay would be reminiscent of Master x Slave but add an interesting twist. I would rather the Kidnapper actually be a psychopath, to something similar. He could have anger issues, lust issues, something similar. I was hoping the RP could get a bit lustful and extreme, but only as the story permits, or in your case, what the psychopath likes. I would only play the boy.
