The Missing Sex Video

I suppose there would be people saying that I am just getting my just reward, but something awful, something dreadful has happened between my nephew and I. It was my nephew who suggested that the two of us should make a recording of us having sex, a sort of sex tape, but this was something I was not comfortable with.
But the following Saturday when he came to visit, he brought his video camera with,and even though I was reluctant to have him filming us being intimate, I eventually agreed to it.
And so it happened that he set up his camera in my bedroom and for the whole of that Saturday afternoon the two of us indulged in sexual activity in a variety of ways and positions which just seemed to go on for ever.
Afterwards he edited the film on our home computer into a half-an-hour presentation and later on that evening the two of us sat down to watch it. I must say that I became very aroused watching the love scenes between the two of us and it did not take long before we became intimate again and started having sex again.
It was while my nephew and I were still busy having sexual intercourse that we heard my two daughters arriving home from their vist to their father.
The two of us immediately stopped what we were doing, and once my daughters were in the house and settled I told them that I had to take their cousin home. On our way to my sister's home, we stopped along the way and had intercourse again. It was only, while making love, that we both remembered having left the dvd disc of our love-making in the dvd player.
But we also felt confident that my two daughters would be too tired and would go straight to bed and would not have the time to watch the movie. I promised my nephew that I would get the disc from the machine and hide it in a very safe place.
But fate has a way of not playing along. When I eventually got home and stealthily tip-toed my way into the family-room, I found my two daughters viewing the disc. The two of them were not aware that I had come into the house, so I snuck out again, waited for about ten minutes before entering the house again, making sure that I was making enough noise that the two of them would hear.
Sure enough, they were not in the living-room, and I quickly made my way to the dvd player to remove the disc. But when I opened the tray, my heart skipped a beat. The disc was not in the machine - my daughters had obviously removed it.
It has been nearly a week now, and during all this time not a word has been said about the disc. But I know that they are holding on to this dusc to blackmail me at some stage.
