NonHuman

Author's Note: This is based off of the movie 'Humanoids from the Deep', which I think should have had a lot more sex in it than it actually did...so I decided to rewrite it. This story is loosely based on the movie, but mostly only as far as the title, names, and the fish-men go. ^.^ - Peggy Larson, a blonde-haired, green-eyed young woman with a DD bust t...

I can't believe what I have done. It all started when my wife told me she was going on a trip south with her girlfriend overnight. Subconsciously I knew I would be butt-fucking myself all night long while my wife was away. I did not know the extent to which I would go. I had to work the day my wife left for her overnight. As soon as she called me from her d...
