v0.09
We’ve added 8 new CGs total. CGs for love event 1 and 2, as well as lewd event 1 were replaced. We’ll be replacing the remaining SW’s CGs in the next update. We’ve added lewd event 4, containing two brand new CGs. We’ve added an option to cook for Mayu, leading to the nip slip CG. After the 3rd love event, you’ll have a new option available when interacting with Mayu, leading to an ear cleaning CG. And finally, I’ve adjusted the prologue a little, also adding a new CG.
In addition, the kitchen H-scene was updated. I’ve redrawn parts, re-rigged, and reanimated quite a bit. Hopefully, things should look smoother now. You can also climax multiple times in this scene now. You can also completely undress Mayu now.
The aspect ratio was changed to 16:9, but only the paizuri and kitchen scenes are drawn with horizontal aspect ratio in mind. I’ll be updating other H-scenes as we keep developing the game, but a few of the scenes will probably remain in vertical format. Things may look a little rough on wider displays. I’ll solve this issue in future updates.

Your sister prefers to sleep a lot, so perhaps this will open up new possibilities for fun adventures! The game is currently in active development and features 5 H-scenes.
