Alien sex

by Nubbins on Apr 22, 2025

The first thing you notice is the vibrator in your cunt. The second thing you notice is that you can't move. You can open your eyes, and when you do, it's to a world of white. White walls, white ceiling, everything lit by a soft white glow whose source your limited field of vision can't see. You can move your eyes, but not your head, to it's hard to see exac...

I saw here a few weeks back that "Old Scratch" had written in with some more of his poisoned crap, and I figured I should set a few things straight. First of all "Old Scratch" ain't that old. He's a bullshitter from the getgo tho' and it shows. For example he sez he was there when Zeus raped Leda. Bwah. Leda's safe in Hades, now, where Scratch has no domi...

They stood almost 8 feet t...

Today was Saturday, and like every Saturday night, Dave was jogging in the woods when he suddenly saw a bright light in front of him. He was a hard-working, 48 year old father of two and really needed his jogs to unwind on weekends! "Huh, what is that?" he went closer ... Behind thick bushes he saw a young blonde standing alone in a clearing. &qu...

Tags up front: male-female sex, blowjob, alien, mind control, submission, male dominant, psychic powers, consent, power fantasy. ***** "I'm only partly with Emily right...

Dear Readers: Hello and thank you again for your positive comments! Chapters 4 & 5 should probably go under the Erotic Horror category, however, it would split the story and cause confusion. The final chapters of Sidney's story are not for the squeamish. Prepare yourself for some creepy-crawly sex that pushes the "squick-limit" in most. Phase 4 – Procreati...

Part 14: Permanent vacation syndrome spreads! Hi all, Not a huge chapter here but I felt like adding something of an epilogue or "end for now" sort of thing. Will there be more? Eventually, maybe. I have several story irons in the fire right now. This one is minimal plot, mostly character development and sexy fun. As I've warned before, I like to keep my L...
