About this game
Sleepy sister's friend is a naughty touching game.
The player, a brother, starts touching his sister's friend while her friend is sleeping.
The game is easy to clear so that you can immerse yourself in touching, but you need to play so that your sister's friend does not wake up.
Saving is automatic, and there is no penalty for game over, so you can immerse yourself in the game without fear of failure.
All actions can be performed with a single mouse click.
You can rub and lick by selecting the rub button.
You can keep rubbing her so as not to wake her up, and new rubbing methods will be added.
As the game progresses, you will be able to remove her clothes and underwear.
There is one stage. The ending is unlocked by increasing the parameters. The ending sex is consensual.
The concept of the game is to secretly touch a sleeping woman rather than forcibly touching her.
The English is machine translated.
