It has been an ongoing game of truth or dare. Kay talks to Mark all the time on the internet, and they enjoy it. Both of them are married to people who aren't willing to try anything new so they tell each other of their fantasies. They met in a chat room around the beginning of the year and have chatted ever since. The advice they give to each other is also a given in their marriages. Both of them want to be with each other, but it doesn't seem to happen.
The truth or dare game is how they reveal their feelings about each other. Mark is a very naughty man with his dares. He so badly wishes that Kay would do all the things he dares in front of him (as does Kay). They started with simple little truths and then moved on to the dares. Kay tries to give Mark some dares to try with his wife to help her with exploring her sexuality. He always comes back with a remark that his wife isn't interested in trying new things. So Kay gets Mark to play with himself while thinking about her and what they could do if they ever met and then tell her the details of the fantasy. Mark always gets Kay to masturbate as well.
