Lustful Sin [v0.4.5] By UnusualFishGame

UnusualFishGame released a new game called Lustful Sin and the version is 0.4.5. The game’s story is about There was once a powerful demon who could control the thoughts and actions of others and use them as it pleased. For thousands of years, the demon roamed the earth, spreading fear and terror wherever it went. Its magic was so subtle and effective that once you were caught in its web, it was nearly impossible to escape. Eventually, the people came together and sealed it away, ending its reign of terror once and for all.

How it work:
