In The Light Of The Full Moon

The bad sanses have been captured, the only ones left to keep the balance is Nightmare. But, Nightmare has fallen pregnant from Killer and Cross, now he is in his passive form, defenceless and without magic.

This is a two part bad sans poly story.
I will try to remove the A/N's as much as possible
