Nightmare cuddles into Errors chest more, who purrs like a cat, his arms curled around his skull, keeping Nightmare close. Dream and Ink left earlier on a date, leaving the other two at home. Error had fell asleep already, leaving Nightmare in silence.
He was getting sleepy though, kissing Errors chest softly, then pecking at his neck, listening to Errors soft breathing. He purrs quietly, as Error shifts in his sleep, trying to roll over. Error whines, trying to roll on his back, but hangs halfway off the couch doing so.
Nightmare puffs up, pulling Error back on the couch, letting him stay on his back. This time, Nightmare shoves Errors face into his chest, Error letting out sleepy protests in grunts. Nightmare kisses his cheek.
"You silly head" Nightmare mumbles, closing his eyes. "I love you."
Error smiles, half awake, half asleep, and mumbles a soft "I love you too." Into the dominates chest.
They stayed like that, sleeping.
