   Summary

   Nightmare allows Error’s new demon lover to move into the coven’s castle, so long as no house rules are broken. Its not as though they would be the first pair he had to put up with constantly fucking. Unfortunately for Nightmare, his brother Dream also learns that a demon has been allowed to take up residence and he has his own objections.
