BlueZoo - NPC Sex Into the Demon Lord's Lair A Sex Free For All Final (eng) - Adult Sex Game

Machine translation

After playing a game until you fall asleep, you suddenly awaken
to find yourself inside the world of the game you were playing.

The sexy demon lord, cheeky nobles, all these NPCs just repeat the same dialogue.

In that case, it must be okay to do anything to these girls...including raw sex, and creampies!
