Roleplaying can be a blast, when you find two people equally into it. Finding providers who are really into it, rather than just doing because someone asks them to is the hard part.
I remember the "Door to door adult toy saleswoman" scene I did one time with a provider who was really into it. She brought her bag of toys to my door, asked for the woman of the house and since she was not there, I invited her to show me what she was selling. The possibilities are endless from here.
Or, playing the shoe salesman for the short skirted woman with perfect lil feet who is looking for that perfect pair. Deciding to tease the salesman with her feet and skirt that seemed to get shorter with each pair.
Or, there is always the babysitter who gets caught looking at porn by the single dad who returns home from his evening out a little earlier than she was expecting.
So many options! But like I said, finding the right partner is the key for sure!
