My latest idea is for a father/son, father/daughter type situation. The basic idea is that they meet on the internet, having no idea who each other is at first. The father is looking for an affair with a younger person. The child is looking for an older more experienced person. For father/son we can add the element of curiosity. After chatting each other up they decide to meet at a local hotel.
For the father/daughter I will only play the father. Sorry, I don't do female characters. I majorly suck at them. It can be a short thing, or it could be drawn out with pregnancy. For father/son I'll play either part.
