Nemurimouto is a game where your sister will be staying at your place for her university’s summer break. She tends to sleep a lot. Maybe you can take advantage of that and have some fun together. The game is still under heavy development, and there are only 8 H-scenes so far. The developer will add more scenes, interactions, game features, sprites, and CGs as development continues.
v0.09
Added 8 new CGs in total. CGs for Love Event 1 and 2, as well as Lewd Event 1, were replaced. Remaining SW CGs will be updated in the next patch.
Added Lewd Event 4, featuring two brand new CGs.
Added an option to cook for Mayu, leading to a nip slip CG.
After the 3rd love event, a new interaction option with Mayu unlocks an ear-cleaning CG.
Adjusted the prologue and added a new CG.
Kitchen H-Scene Update:
Redrawn parts, re-rigged, and reanimated for smoother visuals.
Multiple climaxes are now possible.
Full undress for Mayu is now available.
Aspect Ratio Changes:
Changed to 16:9. Currently, only paizuri and kitchen scenes are drawn for horizontal format.
Other H-scenes remain vertical; some may look rough on wider displays. Future updates will address this.
