Sci-Fi & Fantasy

Nicole and I agreed to call each other immediately when we got home. Nicole's daughter was 16, old enough to look after herself, but not old enough to be trusted alone all night. "Are you going to be okay, with ah... all this?" I said, gesturing indiscriminately in her direction. She had cleaned up surprisingly well. Her shirt was slightly discoloured f...

How To

I read this really great story a couple of months ago, but I can't find it now. I'm sure it had black/blue and/or orchid in the user name, and it was about a girl and her boyfriend at her boyfriend's place for a party, and she ends up sleeping with his cute dad. (If any one knows the story I'm talking about, please PM me! Seriously) I've searched: boyfriend...

Sci-Fi & Fantasy

Author's Note: This is a little something I thought up around Halloween, but only got around to writing now. It stars the main characters from my "Sarah Saga" stories, but you don't need to read them to know what's going on here. * Sarah thrust into her roommate for the final time, and then she leaned into Ashley, panting. Her breasts pressed into her fri...

The Marnott Liaison

Sci-Fi & Fantasy

This novella is set in the near-future (2025-2036) of the same fictional universe as my "Life With Nano", and serves as a sequel of sorts, although you don't need to have read the former to understand this story. I have left myself plenty of room for stories filling in the years between, at some point. Disclaimer: All sexual activity in this story occurs be...

Her mouth wanted to keep sucking, her lips pursing with need. "She's coming out of it now," said a voice, echoing in her head. "Readings are back down to acceptable limits." A familiar head ducked down into her line o...

Hello! I decided to give my friend and DM a helping hand with this erotic sci-fi tabletop he is making! He pretty much made the game himself based on most sci-fi mediums (Star Wars, Mass Effect, Warhammer 40k, Star Craft, etc.) and made it on the d20 system. He's taking a bit of a break and been somewhat discouraged by lack of people participating in his amb...
