Overview
Nemurimouto is a 2D visual novel for players who want a slow-burn, taboo-themed dating sim with a quiet, intimate tone.
Story
Your sister comes to stay at your place during her university summer break. She sleeps often and deeply, and the days together open the door to a relationship that drifts past ordinary sibling boundaries.
Gameplay
Play centers on daily interactions at home, where choices and small opportunities shape a growing romance. Progress unlocks animated scenes and CGs tied to specific events, with new content and character moments added as the story develops.

Changelog
v0.10
A total of 6 new CGs:
- Lewd event 5
- Lewd event 6
- Love event 4
- Replaced the last 3 CGs by C.W.
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.
