The Transformation Device

The Magic Collar

The late afternoon sun slanted through the trees in the park, painting long shadows across the path. Fran kicked at a loose pebble, her usual restless energy humming around her even during a lazy walk. She’s always been like that – petite frame holding a surprising amount of kinetic buzz. Five-foot-three of lean lines, sh...

The Swapping Device - Ch. 09

Okay this is a LONG one. I really wanted to flesh out the world and lore a lot more with this one, but I included a very sexy scene at the end.

I hope you like it!

Breast Size Watch - Ch. 04

Continuing a fan favorite here! Annie is really getting comfortable with that watch, but what happens when Brad wants a go...

Enjoy!

Changing Bracelet - Ch. 03

Here is another chapter to this side story, a whole 22 pages this time!. I'm really enjoying exploring other artifacts. Bit of a different take, but I plan on having this story eventually come into the main series.

Enjoy!

The Swapping Device - Ch. 08

Chapter 8 is here, and the narrative is really starting to pick up! I'm having a lot of fun writing these, and I'm already working on a juicy chapter 9.

Also, I was working to create some covers for each series, and I'm happy to share what we came up with! I hope you like it.

The Swapping Device - Ch. 07

I really liked the direction the story was going in, so here it is uploaded as a PDF.

As a thank you for your patience. I've included the bonus for Chapter 7 for Full Access members, not just Bonus members. Enjoy!

And remember there is still a bonus chapter to chapter 5 available in the Full Access + Bonus tier.<...

Chapter 7 removed due to community guidelines

Hey everyone

Chapter 7 was removed due to it not meeting Patreon's community guidelines for various reasons. As such, I'll need to rework the chapter a fair bit.

To make up for it, I'll post a bonus chapter for Full Access members once the chapter has been reworked. Thanks for your support!

The Breast Size Watch - Ch. 03

The following story takes place in "The Swapping Device" universe and follows another group of characters who have found a different artifact.

A few weeks have slipped by in a blur, and I’m still trying to catch my breath from how fast everything’s moving. It started as a lark, a silly litt...

What artifacts would you like to see in future side stories?

I intend on having these side stories eventually make their way into the main Swapping Device series, so let me know your ideas and what interests you! It could be anything, glasses that let you shapeshift, a pendant that makes everyone around you instantly attracted to you... anything!

Comment below :)

Due to popular demand, "Breast Size Watch" has now been added into the rotation of chapters for Full Access members.

Bonus stories like The Changing Bracelet and other bonus chapters like the Chapter 5 Swapping Device Bonus Chapter will still be only available for Full Access + Bonus members.

I've updated the membership tier descriptions, so head over there if you want a detailed look at each tier after this update.

The Swapping Device - Ch. 06

The morning sun spills through my window, painting golden streaks across my tangled sheets as I blink awake. My body feels strange, heavy in all the right places. I stretch, arms reaching high, and my breasts lift with the motion, full and firm, pulling at my chest in a way that’s still a shock. The cool air brushes my bare...

Chapter 5 BONUS

The following takes place after chapter 5 and before chapter 6, and follows the perspective of Sam and James as they explore their new bodies in the privacy of their own homes alone.

Sam

I’m sprawled across my bed, the mattress groaning under my new, curvier weight. These massive F-cup tits jigg...

The Swapping Device - Ch. 05

The sauna’s heat lingers on my skin like a lover’s breath as Sam and I step out, the air thick and heavy, my body still thrumming from the steam. I’m adjusting the hem of my crop top, feeling the way my breasts shift with every move, when Sam—stocky and vibrating with that manic glee of his—grabs my arm and yanks me...

The Swapping Device - Ch. 04

I blink awake, the morning light sneaking through my blinds like it’s trying not to wake me. My phone buzzes on the nightstand, insistent. I groan, reaching for it, and squint at the screen. A text from Sam: “Yo, you free today? Let’s hang.” A grin tugs at my lips. Sam’s my best friend, the guy who’d...

The Swapping Device - Ch. 03

The Mercedes hums beneath me as I pull into Emma’s driveway, the engine’s purr fading to a soft whisper when I cut it off. I step out, slinging my mall haul over my shoulder, and the evening air brushes cool against my skin. Emma’s house is a modest two-story, all clean lines and beige siding, the kind of place that scr...

The Swapping Device - Ch. 02

I wake up to a strange weight pressing down on my chest, like someone’s tossed a warm, heavy blanket over me while I slept. My eyes snap open, and I glance down. Oh, right. Tits. Big, perky C-cups, still straining against my t-shirt, the fabric stretched tight over their curves. For a split second, panic jolts thro...

The Swapping Device - Ch. 01

I kick a pebble down the sidewalk, watching it skitter into the gutter. Another aimless afternoon in suburban LA, the sun beating down on my neck, making me wish I'd worn a hat. The mall was a bust today--nothing caught my eye, and the crowds were too thick for my liking. Living with my parents at 25 isn't exactly glamorous, ...
