Underfell!Sans X Reader: Lonely Cuddles

"No."
"I didn't even ask yet, Sans!"
"It's still no."
"Whyyyy?! I just want to cuddle with you!"
"I got that, but I said no!"
Finally you just sighed in defeat.
"Fine... I just wanted to... Spend some time with you... Do you really hate me that much?"
Something about how sad you sounded broke his heart. He finally sat on the couch, refusing to look at you.
"...C'mere."
You squeed and ran over, glomping him and nuzzling his belly.
"H-hey, cut it out!"
You immediately began to kiss his belly, watching him as he blushed.
"W-what are you doing...?"
You trailed the kisses up his belly, over his chest, and then you kissed his neck gently.
"Uh..."
Sans seemed a bit unsure. He wasn't used to you taking so much... Initiative. You kissed his cheek before tickling his sides.
"Hahahahahahahahahahahahahahahaha! (N-name)! Hehehehehehehehehe..."
Finally, you pushed him off the couch, making sure he landed on his feet.
"Hey! That's my couch you kno-"
You sat in his spot and pulled him over, making him sit in your lap.
"(Name)..."
You began to cautiously massage his back, watching him practically melt.
You trailed a single finger down his spine, watching him shiver.
You pulled him over on his back, so he was laying in your lap.
He was about to question what you were doing, but you just rubbed his belly once more, occasionally trailing your fingers over them, trying to make sure they didn't tickle too much.
He eventually fell asleep. You giggled and prepared to get up.
Yeah. Prepared to.
Sans's arms wrapped around you and pulled you down with him.
Soon enough, you were laying in his embrace.
Note to self: Sans is a cuddle monster when he is asleep.
You smiled at this discovery, and kissed his belly one more time, falling asleep with him.

"WHAT IN THE- ... Hehe. Goodnight you two."
A blanket was draped over the sleeping duo, as the 'Terrible' Papyrus walked away.
