==========================================
Welcome to SciFantastica: A Transformation Paradise!
==========================================

Looking for a little magic, romance, and adventure? Ever wish you could experience what it’s like to be the opposite sex? Or maybe you’d like to be a fairy, mermaid, or other fantasy creature? What if you got super powers? Or could be young and live forever?

All that and more is possible here.

We’ve got immersive, page-turning transformation stories & sci-fi/fantasy adventures!

Intended for adults only.

=========================
What To Expect At SciFantastica
=========================

*** Gender Transformations ***

Most of our stories are about a man who gets completely transformed, inside and out, into a beautiful new woman. He usually fears and resists the changes at first, but after transforming, she soon discovers she’s actually much happier, freer, and better this way.

A few stories might focus on other things, but male-to-female gender transformations are by far our most popular.

If you’re looking for a story without any gender transformations, check out the TG-Free Zone.

*** Quality Storytelling ***

Our stories pull you in and won’t let go. Lose yourself in a fantasy world. Connect with the characters. Feel like you’re actually, personally being transformed with them.

We avoid overly done tropes and clichés, giving you a fresh take on the familiar transformations you love — with relatable characters, believable motivations, and emotionally-engaging plots.

*** Secret Kinky Fantasies ***

If you have a kink for gender transformations, mind control, fantasy creatures, sexy super heroes, or any of our many other transformation themes — oh yes! You’re in for a treat. Our stories will turn you on, excite your senses, and let you surrender into your favorite secret pleasures.

*** Sci-Fi / Fantasy Lite ***

There’s always something magical, high-tech, or supernatural, but our stories aren’t “hard” sci-fi/fantasy. They’re fairly based in the real world — except magic exists, fantasy creatures hide among us, and modern technology makes anything possible.

*** Romance and Erotica ***

Sex, nudity, romance, or other erotic elements are included in most stories. Even people who feel neutral about gender transformations (it’s just a plot device to them) have become passionate fans. They love the adventure, emotional connection, character relationships, and steamy, sensual sex scenes.

Take this pill and you’ll temporarily transform into the opposite sex for approximately 24-48 hours. Although this recreational drug is “officially” not addictive, using Bender has been shown to be habit-forming. Side effects may include: increased libido, heightened sensitivity to pleasure, and a tempting desire to share this fun experience with others — whether they ask for it or not. These are short stories about individual people who take the pill — intentionally or otherwise — and enjoy the Bender experience first-hand. They’re all self-contained episodes and non-sequential, meaning you can read them in any order.

A Girl's Life by
This original series by DK Masters features “Dana,” a teenage boy who finds himself transformed into a girl after a mysterious encounter with an unknown demigod. Unlike other TG stories that only focus on transformation and sex, this series takes a different approach. Obviously, he gets transformed, and naturally, there’s some sex (in the sequels), but this story is also about exploring the meaning of life, questioning your inherited religious beliefs, finding love, and so much more.
