by TJ19 on Apr 22, 2025

Chapter One: The Joining “What a crappy crappy crappy day” Penny thought to herself as she drove her car back to Pasadena in California. “I mean I even put on a very sexy outfit and all for nothing” Penny's voice echoed through the empty car as her face turned an angry shade of red as she vented her frustrations about the audition. A once in a lifetime sci-f...

Body Shifters: C.L.A.I.R.E. Ch. 01

by xxxecil on Sep 25, 2017
NonHuman

The alien jiggled her tits at me. The creature seemed utterly consumed with sexual innuendo and interest - or....perhaps it thought that I was, and it was all simply to entice me into letting it free. No chance of that happening; I may remind people of the 'absent-minded professor' smart-but-dumb mad scientist cliche, but I wasn't quite so absent-minded as...

Michael had been going to the clinic for almost three years. Each month he travelled to the clinic where he was paid for allowing alien parasites to grow inside his stomach. It was a fairly uninvolved process for him except at the removal process. He was made to shit out rather large insect-like creatures. The only reason why he kept doing it was the money....

"That's just what I wanted to hear!" Lt. Yar had spoken that line on Stardate 41209.3443. Somewhat later, she approached me on the Starship Enterprise and averred firmly, "It never happened." It was commensurate with the latter event that Natasha Yar instructed me to delete any memories I had beginning with Stardate 41209.3443 through Stardate 41209.6630....

Sci-Fi & Fantasy

The hibernation tank lid slid back into the bulkhead with a hiss. Vapor rose from the tank like smoky fog and condensed to form frost around the opening. The figure in the tank stirred, stretched and sat upright. Jenny Jackson, Captain of the freighter, Prometheus, shivered. After a moment she threw her leg over the edge of the tank and pulled herself out....

Author's Note: This series builds off of elements of the previous Panic Moon series. To get the full experience, it is recommended, though not necessary, to read that one first. Hello, fellows!

The water in the tank swirled slowly in little vortices. The geoducks were heaped together in large piles in the back corners. Mindy's fingers tightened on the strap of her purse as she looked them over. The salesclerk stood by, waiting for her choice. A geoduck is a large clam-like thing. Incapable of retracting into it's shell due it's size, it's digging...
