Changed:
- IMPORTANT: While testing the new version, I found a nasty bug that can break any part of the story at any time. Using items from your inventory or even changing your title, could trigger any event countless times, breaking the story and gameplay. The only way to solve this problem was to move it back to the Bedroom. When I came up with the idea to use the inventory anywhere was to make the gameplay more enjoyable, but until I figure out a way to make it work, I can't allow it to break the whole game. Sorry for it.
- Achievements, Inventory and Config can only be accessible through the Bedroom.
- Easier Riley. You won't have to start it all over if you mess up with her.

Fixed:
- Issue where you'd miss a morning talk with the stepsister, getting stuck into a bug on Friday Night.

v0.13.0 - 2025-05-31
Hello everyone! The new version is now available! The Rival System is on with the first option: A Succubus. You will have to start a new game if you want to experience it since the idea of this system is to create different possibilities while trying a new path. This creature will sometimes make your life easier, but most of the time harder. You can expect intense interaction with GF/Mistress and the Stepsister. Of course, the succubus will also play a part with other characters. After a while, you will meet another character which will allow you to get rid of the succubus. You should explore it yourself, but if you'd like to know... The Temple of the Goddess can play a major part in this story. There are four different endings for the Succubus and a little spoiler: One of them can make you a succubus! Being able to change your genitals, control your horny levels, and visual changes for the avatar. It comes with a cost, you will no longer be nice or submissive. If you don't want to be a demon, just break your horns in the bathroom.

v0.12.1 - 2025-02-06
Hello everyone! The new version is now available. It concludes the Dominatrix path and connects to the end-game 'NewSiSco'. You will join another mistress through a train travel towards a Mountain Resort and earn your rest, although, you will keep meeting troublemakers along the way, some of them twice. There is now only one path without conclusion, The Hooker Path, and as you can guess, it will be the next poll's theme. Aside from the new content, there are a few bugs fixed and a new form to report bugs. I believe it will make your life easier and mine as well. I hope the bug report will increase, helping me fix the game. Now, about the comic... It's 95% done. I couldn't finish it for this month, you can expect it within one or two weeks. A bit more than 60 pages, teaser soon! Next month I'll be working on the 'NewSiSco' adding a new function to the CEO's assistant, as you will be attending the Sissy School. That's it for now. Thank you for supporting my work.
