(Fluff because y e s oh and lime)
Killer would sigh softly, turning to face Nightmare who was laying in bed, asleep. Killer was unable to sleep for the longest of time. He would sigh softly, stroking Nightmare's cheekbone. He looked so beautiful asleep, he was usually so tense and on guard but when he was asleep, he just looked so peaceful. Killer could hear him softly humming in his sleep, Killer eyes went half-lidded.
He felt so much safer with him like this, sure Nightmare's protectiveness was enough to keep him safe at all times but...here, laying down everything was quiet and relaxed. Killer would continue to Caress his cheek, he'd push himself closer to him. He pressed a kiss onto his forehead. "You're so beautiful..." Killer whispered softly, pressing another gentle kiss on his neck. Nightmare's eyes would slowly open.
Killer's eyes would widen, Nightmare would give a gentle smile, relaxing Killer. Nightmare's eyes wandered around Killer, he couldn't help but blush slightly. Nightmare would lean forward giving Killer a quick but passionate kiss. Killed's face was the same color as charcoal now, despite them being dating for years, Killer always had gotten so flustered. Nightmare thought it was adorable.
He leaned over again giving his another quick kiss, Killer would huff softly, pulling his closer. "Stop being a tease..." He mumbled (tsundere face is intense). Nightmare chuckled, pulling his chin up to face him and kissed. Killer closed his eyes happily, but soon, the kiss went on for to long and Killer had begun to melt in the other's dominance. Nightmare and Killer broke apart from lack of air.
"Was that enough for you?" Nightmare asked, grinning. Killer stuck out his tongue, Nightmare playfully sticking out his own two tongues. Killer would pull Nightmare's chin down and kissed him. But since Nightmare was taller and had expecting this he claimed his dominance again. This soon became heated when Killer wrapped his hands around his neck, while Nightmare snaked his hands on his waist.
Killer would pull back, smiling. He snuggled his head into his chest, Nightmare sighed softly. Killer yawned, finally tired. Eventually, Killer had fallen asleep. Nightmare would wrap his hands on his back, falling asleep.

Tired. So yeah, I might add a part two.
