College Knights Ch. 01

Transgender & Crossdressers

**** This is my first attempt at submitting some writing to Literotica. Please be kind! This is a stroke story series that contains futanari, transformation, and incest. It also includes somewhat exaggerated (though not absurdly unrealistic or hyper) descriptions of human anatomy. Most sex scenes in this series are futa on futa, or futa on women. If that's...

Faeophobia Quickies: Playing the Field

Sci-Fi & Fantasy

A single drop of morning dew dripped from the penis. Or so it would have appeared to their quarry. In fact the object dangling from the tree was a life-like, phallic replica, 8 inches long, hanging suspended from a silken cord to the pine tree. It had been painted a life-like color; that was important to the test subjects. Or so Professor Cummond had always...

Sci-Fi & Fantasy

This is a continuation of (Don't Have to) Twist my Arm and the transformations get more absurd as Yuuki and Caroline take more of the potion. So, if absurd growth and size is not your thing, I would go back. ***** While crafting a serum to help with recovery after a workout Yuuki unintentionally created something that dramatically increased one's masculine...

Her Initiation

BDSM

Lindsey had never in her life known such an elegant and powerful man. He didn't walk; even when casually crossing the grass with her, he strode. Although he had himself suggested the stroll through Central Park, there was an edge to his demeanor. She could tell he had a purpose beyond seeing her for the first time in the sunlight. She lengthened her stride a...

Sci-Fi & Fantasy

Author's Note: A story requested by a reader. *** Jennifer rolled over onto her side, facing away from her girlfriend. She felt her do the same, their butts pressing together, though it did nothing to add intimacy to the night. After a failed attempt at riling up her lover there was no redeeming it. All they could do was try and sleep, despite Jennifer's l...

(Don't Have to) Worship Me

Sci-Fi & Fantasy

This is a continuation of (Don't Have to) Twist my Arm and (Don't Have to) Keep Me Growing. As such the themes of altersex women having sex and growing to absurd sizes remain. So, if absurd growth and size or women with penises are not your thing, I would go back. As a heads up, this has some demeaning language that is part of a d/s scene as Caroline and Sa...

To Boldly Grow

Fetish

I got home from work at six-thirty. Traffic on the beltway had been particularly egregious this evening, but at least it was Friday. I had a pounding headache from dealing with Maryland drivers and I wanted nothing more than to catch up on shows while snuggling on the couch with Jenna, my partner of almost ten years and wife for a few of them. Except, it see...

Danielle Ch. 09

Sci-Fi & Fantasy

Pleasure wreathed her cock. Velvet walls undulated against the shaft, while the cervix and womb suckled the head as it slid back, then buckled on the return thrust. The room reeked of sex, a heady mixture of sweat, pussy and dick. Tendrils hooked into her sinuses, compelling her to create more. Moisture spattered her thighs and drooled from her cock when it...

Lost Empire Ch. 06

Non-Erotic

Derrick looked at the readings, pausing only a second, he pressed the start button, at first it wasn't too bad. Suddenly it was like the full opening of a huge set of flood gates. Derrick opened his mouth to scream but nothing came out, reaching up he tried to pull the head set off, no dice it only increased the feeling that his head was going to split open....
