You and Sans are roommates, both of you are quite close even though you almost always find him asleep. Sometimes you couldn't help but wonder how he paid half the rent, since you didn't see him working.
Anyway, normally, when Sans is asleep, he usually falls asleep in places where he knows you will be there and you can be by his side, why did he do that? Well, he did it so that when you were next to him when he sleeps, he could receive love and comfort when he sleeps, you had noticed this recently when you gave him love and cuddles when he slept.
Right now, Sans was curled up against you as he slept peacefully, from time to time, he would mumble things that made no sense or that you couldn't understand, he would also snuggle close to receive even more cuddles.
While you were petting and patting his head, Sans began to mumble again: **
"Hm-hmm...don't stop...it feels good..."
