Sans X (Fem) Reader {BIG DADDY KINK!!}

Part 1

You were standing at the counter,
washing dishes before handing them
off to Sans as he dried them lazily and
put them away, usually still wet. This
part was normal. Papyrus was out
with Undyne who begged him to come and confirm that anime indeed does exist when she went to Alphys' house. That part was also strangely normal. Sans' grin was pulled just a bit wider tonight as he constantly side-eyed you, letting the silence hang in the air as awkwardly as possible. You puffed your cheeks out and pouted into the soapy water- this part wasn't normal in the slightest. Usually, things would be loud and silly. You'd probably splash water onto Sans and he'd playfully tackle you, and you'd try not to get aroused by him looming over you, face dripping water onto yours, his boney hands digging into your shoulders..
"Someone's being awfully quiet, huh?" You were pulled from your blissful memories and almost dropped the cup you were washing back into the sink. You quickly handed the dish off to him.

"I don't know what your talking about I'm just tired. " You said a bit louder and more firmer than needed, but Sans just kept smiling in badly drying. It was all your fault and Alphys; it was her fault too. She was the one that excitedly wanted to watch Free! And Magi with you late last night. She was the one who had you laughing so hard you woke the skeleton brothers up. She was the one that started the game of truth or dare that pulled the most mortifying in compromising words out of your mouth as the skeleton brothers tiptoed downstairs into the living room. it was definitely a weird scenario: here you are, sitting in the living room wrapped in 4 blankets on an old couch with your laptop on your lap playing Mew Mew Kissy Kitty 3: The Kissening, on the phone with your reptilian from to whom you just admitted a list of your most depraved kinks, at three in the morning as two skeletons stare at you in complete shock. You were sure to sum this would sound hilarious... It wasn't...

Ever since then sans has been treating you... funny. His smile was not stopped and he seemed to be... closer. Not uncomfortably so but you felt like a tsundereplane every time the sleeve of his hoodie brushed up against your bare arm.
Papyrus hadn't really understood
most anything you said that night,
and in the morning, just asked if'you
guys were talking about anime' with
a wary expression that was quickly
wiped away once you hurriedly agreed. Sans had snorted into his coffee at your blatant lie, but only responded to your glare with a wink. That bastard had nerves of steel and you were like an angry marshmallow. But now it was stifling. Ever since Papyrus had left, he had been dead quiet like he was trying to bait out of you whatever horible words were perched on your tongue - and it was working god dammit! You fumed until you realized you were angrily scrubbing the same fork this whole time, and that Sans was approaching you.

"I think it's clean enough, amazingly."
He quipped, wrapping his bone dry (ha) hands around your wet ones to pluck away the fork. You felt your cheeks light up and you kept your head as low as you could, but he didn't move away. He got closer, positioning himself so he was behind you. "For someone who's so tired, you seem to be breathing pretty fast... you sure you're okay?" He breathed in a calm voice, but the laughter was obvious in his tone.

"Im fine." You tried to snap, but it came out more like a whine as his hands pressed your hips gently.

"I mean.. if you need someone to talk
to, I can always listen.." he drawled.
Your heart almost ruptured when his
fingers curled inward around your
hips, "You know, I can almost be like a
second dad, right kid?" That asshole!
This bastard! This absolutely arousing
sack of bones was making your knees
weak! He noticed and pressed his ribs
into your back, trying to keep you
steady.

"Sans, cut it out..." you murmured,
teeth digging into your lip.

"Why? You like it, don't you kiddo? I
mean, I always knew you were into
me, but the daddy kink thing was a
shocker... But hey, maybe Im just a
bonehead."
