"This is the last stage of your training, Adam." "I-I..." "You want to be strong, don't you, my little knight?"

My first story! All characters are over 18. This story contains heavy alternative themes, notably furry and futa, with even more to come. If that is not your thing, don't read it! Otherwise, enjoy! ***** Chapter 1: The Book I walked into my apartment, giggling to myself, and made my way into the living room, unsurprised but smiling nonetheless to see my...

And what the fuck happened to you?!" she thought. Alice smiled, "Oh, I was just passing through, decided to drop by, check on old friends." Her smile was predatory, her gaze, seductive, and she l...

Celebrities & Fan Fiction

Warning: The following story contains a little bit of just about every possible sort of sex one can have, and in some cases, some sorts of sex that are impossible for us non-powered humans, no matter how hard we wish we could. Enjoy, and if you find parts of this offensive, well, just remember, it's only a story! I can only hope that if you weren't a fan o...

In the quarters of Zatanna the Magician at the Hall of Justice, the woman sat at a table surrounded by trinkets and books that she had been collecting for some time, not for any dire situation really, just a hobby really. NONE of the items were dangerous, not by any stretch of the imagination but they were certainly powerful. One was a crystal ball that told...

Chapter 5 THE WIG WAS PERFECT After nearly killed myself with my eyes rolled back in my head doing 85 miles an hour. I snapped I was driving and started to slow down to the speed limit and get control of myself, my cock and my pants.

Erotic Horror

Author's Note: This story contains human-to-beast transformation, magical compulsion, a very demanding woman, and much more.

It sits somewhere between Erotic Horror and Fantasy,...
