This is a game where you do night crawling without waking a "tsundere" sister-in-law. As you interfere with your sister-in-law, you can undress, lick (cunt, arse), rub, titty fuck or fingerbang her.
If molesting someone in their sleep is your thing, this game will get you where you need. It's rather difficult and some people have the nerve to google cheat codes, can you believe that? People dont care about playing the game, just molesting
The game takes a lot effort just to get the ending. When you do get the ending though it's not even worth it, as it's only a few seconds and it immediately takes you back to game screen. Overall, this game is a test of patience and is only good for people with a certain type of fetish.
This game is very basic. It has a small handful of things you can do which increases the meters which will end in a game over once one is filled. If you really like the sleep molestation genre then you may think it's worth it. But overall there's many other games with more/better content for the same price.
