I struggle with role play scenarios, my problem is I don't find many of them hot ! for example, 'step into my office, I'm the boss' .. I couldn't do that, I find school girl kinda creepy.
I once asked a girl to do some light domination I guess, with the roleplay being she's in charge and blah blah blah.. but halfway through explaining it I just said 'oh don't worry let's just get to it'
I'd like to hear some other ideas from people, I'm not against trying it. However I always fast forward through the story in porn vids so I guess I'd be too eager to just start.
