Gaster x M!Reader ~ Overworked

(Y/N) POV

The house was quiet at this time of day, I had just put Sans and Papyrus to bed like every night; I currently sat at the kitchen table as I waited for the water to boil for my tea. I flipped through the book that I had brought with me, the words dancing about the pages with images crossing my vision. A high-pitched whistle brought me back to the real world as the kettle began to bubble up, I left my seat and picked the kettle off the burner.

"Now, Chamomile or Jasmine Tea?" I asked myself, looking through the tea cupboard before picking out a Chamomile teabag. I grabbed my mug and poured the water, humming quietly as I unravelled the teabag with grace; shuffling noises back from behind me as the front door shut almost inaudibly. I reached for the sugar as a hand placed itself on my shoulder and a shadow appeared behind me, I had a strong guess as to who it was.

"Hello love, would you- GASTER!" The full weight of his body collided with mine causing the hot water to spill on the counter slightly. He draped one arm over my shoulder while his other wrapped itself around my tiny waist; his grumbling made him seem childish as his forehead pressed itself to my shoulder blade.

"Seems someone has pulled another all-nighter this week. Such endurance!" I mocked, making my tea in the process.

"So close..." he mumbled, swaying slightly from his lack of sleep.

"To what? Another mental breakdown?" He pity laughed at my joke before squeezing me tighter, his skull kissing my neck lightly. I leaned back, holding the warm cup of tea up close to my chest with a small smile on my face.

"Unsolicited affection, not really your thing. Or do you really want me that badly?" I teased, Gaster said nothing. "You're so romantic," I flatly stated. We stood in silence, enjoying each other's company from what I could tell; I sharply inhaled with a sigh of exhaustion to match his own.

"Ha-ha, you're such a dingus. You should stop doing this to yourself, dear." I gave Gaster my tea as I spoke with a hum in my voice.

"Thank you," he said into the cup, sipping calmly. I handed him the cup, moving to the table to pick up my book and head upstairs.

"The boys are in bed already, come join me once you've finished down here." I kissed his cheek before heading up the stairs to our shared bedroom, I got dress into a pair of pyjamas with ease before wrapping myself up in the covers with a sigh of content. I lied in bed, listening to the natural sounds of the house along with Gaster's movements through the house.

"Well, don't you look cozy," he hummed, turning on the light so he could get dressed. "Mind if I join?"

"Sure, why not!" I said, making room for him as he turned the lights off, "stop overworking," I ordered, snuggling up to his just. I received a low hum before his soft snore rung in my ears as I too drifted to sleep; the next thing I knew, I had woken up to my husband and two little children in the bed with us, snoring happily.
