A game about sneaking into your little sister's room at night and having some sexy fun.
All the nocturnal naughtiness is animated super-smoothly with Live2D.
Use the mouse to freely control your hands, tongue, and dick, and go wild on your little sis!

- Tease four different areas at once!
Caress her nipples with your left hand, play with her pussy with the right, and kiss her as she pants...
Do all that and more! And of course, get up to plenty of mischief while penetrating her, too.

With your dick, your hands, and your mouth (tongue), there are all sorts of ways to play.

- Ten different epilogues!
After you've had your fun, your little sister's reaction (or objection?) will change depending on what you did.
Enjoy seeing how she feels after you cum inside her or forcibly keep going after waking her up!

[Story]Our little sister heroine lives alone with her big brother. She's quite thankful to him for always working
so hard. But one day, she noticed that her brother's been sneaking into her room and watching her sleep.
She's shocked at what a pervert her brother really is, but even so, she's grateful for all his help.
And so one night, she leaves the door unlocked...
