"Overheard" by Unknown Author (mcg-mcg@bartra.demon.co.uk). The man comes home early for work, and so his wife doesn't know that he is able to overhear her while she talks sex with here neighbor on the telephone. The two ladies talk about various sexual exploits, including how the man's wife will agree to come to the next orgy if the neighbor can manage to seduce the husband before that time. This is a very interesting approach to voyeurism and spouse watching.
The story is posted by Merrill, Castle and Gray (UK). These people claim to have a list of 7000 stories, and it appears that they are willing to send them to people for free. I have not received stories directly from them; but I did recognize several good stories on their list. I plan to review a few more of their stories in the next few issues of Celestial Reviews. You can e-mail 'list-mcg@bartra.demon.co.uk' for an up-to-date list of their publications
