My Step Sister Is My World

My Sister Is My World is a text based erotic story in development for PC, Mac, Linux and the web. An Android build will be added at a later date. This game is very early in development and may change significantly during development. I hope you enjoy the game as it progresses towards a full release!

Story & Gameplay

You have been away for 7 years because of work and you have finally arrived back home at your new apartment. You remember your step sister and how cute she was and how much she wanted to marry you once she grew older. But it turns out that during those 7 years, your step sister has become a gyaru and she hates your guts! How will you get closer to your step sister? Choose from available options as you progress through the story!
