The only shared premise among them needs to be that they find themselves, however you decide that happens, in this universe and, as The Eagles would say, "You can check out any t...

The disease was transmittable through sexual activity and, as its symptoms and causes became more well-known, it got classified as an STD (Sexually Transmitted Disease) very quickly.

Well of Three Wishes

Sci-Fi & Fantasy

This story contains some absurd levels of growth. If mini-giantesses with huge boobs are not a thing you enjoy, this story is not for you. It also has a reality bending component, if you like simple, straightforward transformations, this is a far cry. ***** It had been billed as a mystical place as part of the Magical Ireland Tour, but as Myra and Leela lo...

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

CHAPTER 6: NEITHER WITH A BANG, NOR A WHIMPER As is always the case, various sections of the community clearly saw the danger early and did their best to warn the authorities and the people long before any official attempt was made to tackle the problem. And, as had always been true, by the time the governing bodies did stir, it was already too late. Media...

A Circular Solution

by mistyfdfa on Sep 16, 2017
Sci-Fi & Fantasy

This story contains sex and gender change shenanigans as well as brief gay sex. If either of those things would bother you, I would hit back now. ***** Thinking back, it was the silent car ride as Kris and Rob returned from a gathering with his family nearly nine months ago at New Years that kicked everything off. Their continuing struggle, which was reall...

A Platonic Relationship Ch. 03

Sci-Fi & Fantasy

PLATO is the most powerful computer ever... grown, but he knows that he is incomplete. He needs something else from Marcella, and once he has received it, he gives her... and Richard a gift they would never have dreamed of asking for. This story stands- more or less- on its own but might make more sense if you have read the previous chapters. = = = = = = =...
