Fetish

Springwood Fertility Research Facility-Chapter 1 My name is doctor Byron Johannson and I founded the Springwood Research Facility in the fall of 2019.

Springwood's mission is partly to pair non-fertile couples with acceptable donors, but to study the effects of s...

Erotic Couplings

Part II: The Insemination Chapter 5 Day one: Very little conversation occurred between Tia and Tim as they started the 15 mile drive through the countryside to The New Life Center.

Loving Wives

I awoke to find myself curled up to Lori's back with my right hand grasping one of her big breasts. We had been spooning like this every night that I had been home rather than out of town on my incessant business trips during the two weeks since our return from the convention in Vegas.

Backing Up

Sci-Fi & Fantasy

"Ah," she grinned. "Good! Very good! You are weak! Very weak! I will wreak my pleasure upon you!" I struggled half-heartedly, but to be honest I was loving her show of superior strength. Besides, I could feel myself right on the edge of orgasm, and her vagina was deliciously tight around my dick. -------- We had met innocently enough. My ship had come in...

Review: Switchhitters

Reviews & Essays

Another great anthology of erotica that I highly recommend is SwitchHitters, edited by Carol Queen and Lawrence Schimel. I purchased this book for the main purpose that it included a short story from Laura Antoniou, the author of The Marketplace series. Her particular entry in this anthology is about one of the characters from the premiere book in that serie...

The Babymaker of Springwood

by blozo on Aug 28, 2018
Loving Wives

WARNING: If you want bad things to happen to women who have sex outside the marriage, or to the men who have sex with them, click the back button NOW. This is an impregnation fantasy. There is no "Burn the Bitch" ending. It is also an utterly improbable concept, which in real life would result in the immediate and permanent revocation of the licenses of a...

Erotic Couplings
