The Magic Collar - Ch. 8 [With Images]

Things are going well for Matt until a friend of Fran's unexpectedly shows up at their apartment... during one of their livestreams!

Read it on my website!

The Magic Collar - Ch. 7 Exclusive Bonus Chapter

Today's bonus chapter is a new format I wanted to try out.
It takes place after Fran and Matt had setup Karma’s OnlyFans, which is what occurs at the start of Chapter 8. This is just a side story.

Let me know what you think of this different format! It was fun to make, and I think it came out great. If you guys like it, I can start do...

Official vote on the next mainline story!

The two mainline Wednesday series are coming to an end.

Here is when you can expect the final chapters...

The Carnal Labyrinth (Rounds 4-5) - A Magical Board Game Story - Ch. 2

Back due to popular demand! I hope you guys enjoy this follow up to a fan favorite.

Announcing my NEW WEBSITE!

I'm so excited to announce my brand new website!

johnmantd.com is now live.

I've been working on this for a while, and I finally finished migrating everything over to the site. At the start of this Patreon journey, things were good because there weren't that many stories...

I'm curious...

Progress on the new comic is coming along well, I can't wait to share it with you all. But I want to know...

Would you prefer I release it one page at a time, or all at once?

I haven't figured out the release schedule yet, but for example, I could do 1 or 2 pages a week, or I could do 6-8 pages in one go at the end of every month. Th...

An update to patreon tiers

Hey everyone!

Just wanted to share a little update. I've decided to restructure the way my Patreon Tiers work. The overall benefits will stay relatively the same, but I wanted to make it a little more clear what you get at each tier.

I'm also working with artists to start adding in comic pages to the ongoing rotation. I haven't decid...

Working on something new...

I've been working with an artist commissioning them to turn one of my stories into a comic. Stay tuned for the first pages to be released soon!

Any guesses which story?

[Poll] What is your favorite story of mine?

Next month I will be doing another poll to determine which story becomes the weekly wednesday chapter in place of The Magic Collar and The Challenge App when they finish (don't worry, still plenty more chapters for both to come), but I still like to check in to see what everyone is enjoying the most.

Let me know below which is your favorit...

Where did you find my stories?

Another quick poll just to check in on all the new members... and to see where I should be posting my public stories!

Changing Bracelet - Chapters 1-3

This was an old favorite, so I've decided to reformat chapters 1-3 to share again since when I originally posted this it was done as just a standard text post.

Let's just saw the story isn't over... and you can expect a new addition VERY soon ;)

People seemed to like the last chapter, and I had so much fun writing it that I decided to do chapter 2 this week, with images yet again!! Not every Friday chapter will feature images though, so don't get used to this, I just really like this story. For the image version, checkout the other post lab...

[Final Update] Yikes... I'm a mess. Sorry for the mess ups!

Okay so I accidentally posted this Friday's story incompleted and early. I was drafting the post to get it ready, but I still had a few tweaks to make to the story, and I accidentally hit post! Patreon sends out email notifications when I post, so some people would have received it and can see the post early. Stupid me! Big oopsie.

But the...
