The Arioch Family Universe
The stories set in this universe take place in a world that's very similar to the modern-day world we live in ... except that some families in this particular universe are a lot more curious and willing to act out on their incestuous fantasies and desires.
That, and a lot of otherwise bright, beautiful women in this universe - as well as their partners - are shockingly clueless and/or careless when it comes to matters of birth control. Nearly all of the stories in this universe invariably lead to a sexy woman getting a rapidly-swelling tummy ...
Loosely inspired and influenced by the classic erotica written by Kathy Andrews.
