I didn't think it was possible, but Mark had been a very naughty boy. Again. It wasn't enough that I had punished him once... or twice... it just seemed that he could never get enough of it. Maybe he was just lonely and thought that any attention he could get would be worth it. So I would be more than happy to oblige him.
I heard the knock on my apartment door at exactly the moment I told him to arrive. When I didn't answer, I knew he would use his key and let himself in, thinking he would be surprising me. Little did he know!
