My plan was set. Now all I had to do was wait; and oh man, that was hard. Time went by at an agonizingly slow pace. I got up and peered out the window...each time a car cruised down the street. Finally, at just after midnight, a car came down the street and pulled into the driveway. Kim was home. My heart was THUDDING in my chest; my mouth was bone dry; I was so excited. It was an eternity until I heard a noise at the door. I heard a thump and keys jangling. I continued to hear keys jangling and. "Oh my gawd Robbie. That was absolutely fantastic. I never knew sex could be so good. So marvelous. I can't believe I wasted all those years." She said as she reached back underneath her inspecting her asshole. "Oh my, I am a kind of tender down there now you dirty boy." Mom said laughing."I am only as dirty as my mother." I replied as I slid my hand down to finger her wide open cunt."Mmmm." replied my mother." Holy crap Mom, I can't believe how wet you are. You must have really enjoyed that.". ” she cried. I just managed to pull out in time and ejaculated all over her tummy and tits some even ended up in her hair. I had never in my 55 years cum as hard as I did with my mother in law. Before we cleaned our selves up I had one last lick of her now piss soaked fanny boy did it taste good, it looked good as well all red and puffy. I asked my mother in law if she had enjoyed it, as I helped her up, she just through her arms around my neck and gave my a full blown passionate kiss open. Instead, the scientists of this country have used advanced genetics to create a multitude of humanoid species, commonly referred to as demi-humans or just demis. Examples of demi species include cat-girls, dog-girls, or even fennec-girls. They all share some physical traits with their animal namesakes, such as fluffy ears and tails. Other than that, they also share less obvious characteristics, like a superhuman sense of smell, hearing, sight, or certain mental qualities.Demis are commonly bred.
