A downloadable game for Windows, macOS, and Linux

We are pleased introduce to you our new game:

My Strange Sis

This is a story about a guy who ran away from his family, to study in a different city. More accurately, he fled from his sister, for whom he has feelings which are more than 'fraternal'. This is a game about B/S incest. And there is plenty of it. Hopefully, this will not be just 'another' incest game. What makes it different from the rest?

Firstly, the storyline in the genre of modern urban fantasy. The story takes an important part in the game. As should be expected, there will be several variants of development to the plot, with different endings.

Secondly, we will make interactive and animated sex scenes.

Third, the main character can have different personalities, that will affect the game later.

Lastly. Despite the fact that there is only one female character in this game, we will try to make her as custom as possible. From her appearance to her traits. This will also affect the game-play.

The main adult content are:

- B/S incest

- M/F

- some TF themes

- sleeping, voyeur, and other stuff that you can expect from incest game.

UPD: 0.31 changelogs:

The latest build of My Strange Sister v0.31 is now open to the public and free for everyone.

The secret of the Liz will be revealed. Also, there is a new interactive and animated sexual event in this version.

There will be several choices, the consequences of which you can only see in the next versions. You must start a new game to play it without errors.

Great game! I like how this game allows players to customize the girl's looks and her relationship to you (related by blood or marriage). I also like the mini-game where you must open the bathroom door slowly to spy on your sister in the shower. Looking forward to the final version!


Hi! We are glad that you are liked our game. This version have another sex event, i'm suppose that you can't find it yet.


Cool ... I'll have to uncover it. Keep up the good work!


Now this is a good idea. I love the fact you customize the girl too in this one.
