You can now watch Adult Time 50,000+ adult movies on your FireTV stick or device! Because of the nature of the content and Amazon store policy, the application need to be side loaded.
Sideloading a Fire TV device is not very difficult, but it is significantly more complicated than downloading and installing official apps.

Why Should You Sideload Fire TV Apps?
Sideloading is a process that allows you to install applications that are not available through the official Amazon app store. This allows you to run Android apps that you otherwise would not have access to, like Adult Time.
Before You Begin: Install Downloader and Prepare Your Fire TV Device for Sideloading
The first thing you need to do is install Downloader app and prepare your device for sideloading. For security reasons, Fire TV devices are not able to sideload apps unless you change two settings. This is an easy process, and you only need to do it once.
1. Search for Downloader using the search function or Alexa voice search.
2. Locate Downloader and select it.
3. Select Download.
Note: This app is free, but it’s still added to your library when you first download it on any Amazon device. If you have previously used this app elsewhere, you will see a You own it message. You still need to download it to your Fire TV device before you can use it for sideloading.
Wait for Downloader to install, do not Open it Yet
4. Go to Developer Options in Settings
Now that Downloader is installed, and you haven’t launched it yet, you need to change a setting on your device.
If you have any Fire TV box, Fire TV Stick, Fire TV Stick 4K, or Fire TV Cube, navigate to: Settings > My Fire TV > Developer Options
If you have any Fire TV Edition television, navigate to: Settings > Device & Software > Developer Options
5. Enable Apps from Unknown Sources.
If you have a Fire OS 7 device, which includes Fire TV Cube 2nd Gen, Fire TV Stick 3rd Gen, Fire TV Stick Lite, Fire TV Edition televisions by Grundig & JVC, and 2020 Fire TV Edition televisions by Toshiba & Insignia, select the Install unknown apps option, scroll to Downloader, and change its setting to ON. 
If you have a Fire OS 5 or Fire OS 6 device, which includes all other devices, select Apps from Unknown Sources to change the setting to ON.
Note: You DO NOT need to turn on the ADB Debugging option.
5. Open Downloader and Grant Storage Permission
Now, go to your list of apps on the Fire TV Home screen and open the Downloader app. If you have a Fire OS 6 or Fire OS 7 device, as soon as you launch the app, you will be asked to allow Downloader access to files on your device. You must select Allow.
If you accidentally dismissed the prompt or selected Deny, then reset the app by following this guide.
Your Fire TV device is now ready to sideload and you can now install any app!

Happy Adult Time!
Has anyone figured out how to fix the videos stopping after a few minutes of playing ?
Make sure to update the software on your FireTV. Let us know if you still have issues after updating.
The videos play for 1 minute then pause using my firestick.. Anyone else have this problem and how do I resolve it?
Happens to me as well. Have not found a resolution.
How do you unlink a device? I uninstalled the app from my android bx. How do you know how many devices are linked to your account? How many can be linked to an account?
Thank you for making Adult Time available in FireTV, I just wanted to ask if some of your partner sites (like Evil Angel, Elegant Angel and Girlfriendsfilms) are also available there, as their own app in ROKU is being dismantled.
Thanks for making adulttime available on firetv! Now that Roku killed the adult apps I am shifting everything to FireTV and this works great! My partner and I are back to watching spicy content on our TV!
How can I download this app straight onto my Samsung TV? It’s a 2021, 4k TV. Don’t have firestick and not using my roku because I have all of my other content and subscription-based apps on it
Ive got a problem with new videos which are available in 4k, while streaming this videos my stream often breaks down after 2 to 3 minutes. Older videos that are only available in Full HD working without any problems. Is there a way to set the maximum resolution of the video stream down to 1080p in the FireTV app (in the future)?
the problem I posted has been fixed
Install was easy as pie!!
Success! Thanks Adulttime dev team.
Thanks for instructions. Worked a treat! Do videos automatically playback in 4K or highest resolution (if no 4K)? I cannot see any options for the picture quality. Thanks
Is this app option available for AppleTV or Roku?
Does Amazon „see“ what I download and use?
No, the app doesn’t communicate any information to Amazon.
Awesome tutorial. It works on my 4k Fire TV! Fast sideloading and activation. I love that app.
Is there a way to change the cc language soon ?
Thanks Fapboy. There’s no way for the moment to change the subtitles to a different language then english.
Sweeet! Worked like a charm! My new favorite Firestick channel!
