Adult PC Game: Nemurimouto Ver.0.08 by pachipoi Win/Android Archive

Overview:
Your sister will be staying at your place for university summer break.
She tends to sleep a lot, maybe you could take advantage of that and have some fun together!

The game is still under heavy development, there are only 8 H-Scenes so far. I'll be adding more as the development continues, as well as more interactions, different game features, sprites, CGs, and more!​
