Big Brother! Kris x Sick! Reader

Requested by the lovely Windy423!~

Kris held you piggyback as he waited for Toriel to finish gathering her things. You'd gotten sick during class, and so you three had to go home for the day.
Kris, the lucky duck, had the immune system on the gods, so none of you were worried about him getting sick. But still, he was going home because you clung to him like a starving koala when you were sick.
Kris pressed his cheek onto your head as you buried your burning face further into his shoulder, grimacing at the slight bounce in each step as he carried you to the car.
You all arrived home in just a few minutes, and Kris carried you inside, bringing you to your room and setting you on the bed.
Toriel followed soon after with a thermometer, taking your temperature as Kris dug out the large fan and a set of lighter, clean clothes for you.
"101..." Toriel muttered off the number from the thermometer, "Any other symptoms, dear?"
You patted your throat, making a dry, raspy sound. At the sight, Kris passed the new set of clothes to Toriel and stepped out the room, footsteps headed towards the kitchen.
Toriel helped you into the new set of clothes, setting the old ones in your laundry basket.
"Are you hungry, dear?"
You shook your head, watching as she nodded, passing Kris as she stepped out of the room.
Kris walked up and sat next to you, gently running a comforting hand over your forehead and cheek before helping you sit up to drink. He made sure not to let you drink to much at once, setting you back against the pillows before going to flip on the fan.
Toriel returned with a cold cloth right about then, gently draping it over your burning forehead.
"Do you need anything else, sweetie?"
You shook your head, leaning into her palm before she pulled away.
"Alright. Well, if either of you need me, I'll be in my study."
As she left, Kris sat down on the edge of your bed, keeping you company as you fell asleep.

You awoke, feeling groggy. Sitting up, you pulled the warm rag off your face and set it aside, reaching for the glass of water. You drank your fill before setting it aside again.
Out of the corner of your eye, you saw Kris poke his head into the room, then leave a moment later.
You sit up slowly, rubbing at one eye. Slowly, the smell of food wafts down the hall, smelling of bacon, toast, and other delicious things.
Kris soon returned with two slices of toast and a perfectly cooked egg, handing the plate off to you before reaching out to feel your forehead.
He hummed quietly to himself, moving to take the warm rag and empty water glass before slipping out of the room once more.
You ate slowly, making sure each bite stayed down before moving onto the next.
Kris returned once again, handing you a glass of ice water and setting a fresh, cold rag on the back of your neck.
Kris sat with you, providing you with idle chitchat until Toriel called him back to the table to finish his breakfast.
Throwing a soft smile your way, he gently ruffled your hair and took your empty plate before disappearing from view.
Nine out of ten says he's already done your homework.
