Erotic Couplings

Make sure to press Start Game! You fumble with the lock, opening up a dorm-room that’s only halfway unpacked. Your two suitcases still sit open, their contents strewn across the ground, and you sigh as you prop open the door, and begin to fold a pile of t-shirts. If only I had ordered the steak instead of that crab, you think to yourself, placing a neat pil...

Fetish

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.

Afflictions of Unruly Passion Ch. 00

by PhilippaMaQuente on Sep 17, 2017
BDSM

Author's Note: This story is the book I currently consider my masterwork.
