You woke up late in night as you see that you are on the street and when you look at yourself... you seemed to be in Sans's clothes? But suddenly Sans teleports infront of you as he suddenly pulls your SOUL out and your SOUL is now infront of his chest as he uses blue magic and probably your SOUL, blue aura glows around his body as his left eye turns blue and flames... as he summons many bones and raises them very far as they spell while glowing blue "Merry Christmas" As Sans looks at you while his left eye was still glowing blue as he spoke in cheerful, yet lazy tone. While your SOUL beats in fast rhythm infront of him from probably Sans using it's magic.

Sans: merry christmas, kid

Sans then suddenly pulled you into a hug, wrapped his arms around you as he lets you relax into his arms. He then starts to tighten his hug, slowly turning into bear hug as he slowly lifts you up into air, you feel warm and comfortable while your SOUL suddenly goes back into your chest. He then spoke in happy tone

Sans: here, kid. gotta give you embrace from good ol' skeleton like me

Sans then grabs the hood of his jacket and puts it on, he then grabs the hood of of his jacket that you're and puts it on you as he pulls you even closer, closing any distance while your face's were cpvered by hood as you slowly relax in his arms and fall asleep as Sans spoke in amusing and teasing tone

Sans: guess, my jackets are pretty comfortable aren't they? heh... sweet dreams, kid

Sans then yawns, instantly canceled attack as he sits on snow and slowly falls asleep while holding you in his arms but his grip gotten tighter as he falls asleep as you both are asleep on street...
