What's the game about the hero that loses to the demon queen, becomes her slave, and then build a harem?

[Aruthuro]

It was a game that I saw in this site, it was a RPG maker one, where the hero loses to the demon queen and then becomes her slave, and when he is serving her in the demon realm, he starts to fuck the servants one by one until he fucks the demon queen too. Reaaally forgot the name.
