Falling Down Slowly... A Undertale Love Story (UT Sans × Frisk)

A Sleepless Run...

Ima say this now... This is not a child friendly chapter... Like its way worse then chapter 15... I'm kicking myself for this but I still plan to do more in the future... Let's hope my family never find my Wattpad and my friend Sammi doesn't strangle me later... Also dream Frisk and Sans are realy confusing so I might do something like last chapter;

Sans and Frisk had gotten scolded by Papy when they both came downstairs after getting dressed, Frisk had decided to just get into her PJ's which were a tight grey turtle neck with longsleaves, like always, it looked really different considering she wasn't wearing a bra, instead of it looking more flat it took on the sharp curve of her chest to her stomach, she also had some shorts on that the semester had made her that tiabi honest were kinda too short... but she didn't care since they were all going to bed after eating, plus she hated the feeling of loose pants, especially when trying to sleep.

Papyrus didn't have the time to remake the sauce for the spaghetti, so he had to use a can which he really wasn't happy with. But it didn't really taste all that different in Frisk's and Sans' opinion. They finished and Frisk helped Paps wash the dishes, he always saved the knifes for last so he could send Frisk to bed as her recounted and hide them. She felt sorry that they had to do that for her, but also happy that they cared about her well being... Even when she didn't...

She made her way up to Sans room to find him already asleep. She crawled in next to him and pulled the blankets up over them... It was going to be a cold night...

~··········~

Sans was awaken to movement and a pressure on his lower 'abdomen', he opened his eyes to see Frisk sitting on him, "Wah ah! F-Frisk W-What are you doing!", his face flushed a deep blue, but she didn't respond and simply continued in her movements, it was at this moment he realised that she was still asleep.

Frisk on the other hand was having a dream similar to the dream she'd had a few day's prior, only her and Sans were back in the bath. She had been sitting between his legs when she suddenly felt something hard on her back. She turned around to find the bubble had tuned blue from something glowing underneath them... Sans wasn't looking at her and she could see a deep blue blush on his face, the same color as the bubbles.

Without even thinking her body move on impulse as she turned herself around and placed herself slowly above where the glow was originating from, her chest was now fully above the water and right infront of Sans. He had noticed the sudden movement of the water and had turned back to a face full of Frisk, he wrapped his arms around her waist, as he began licking and nipping at her chest. Frisk slowly lost feeling in her knees as she slowly lowered herself onto his very hard member, as it and the water entered her. But Sans was impatient... Holding her hips and still playing with her chest, he slowly increased speed and pushed her onto him, Frisk moaned at the sudden movement and threw her arms around his neck, pushing her chest closer to his face. It wasn't long after that she was fully on him, then once again the instincts kicked in and she began moving slowly, softly moaning as Sans continued to play with her chest.

In the real world Sans was trying very hard not to let his magic surface as Frisk placed her hands on his chest and increase the speed of her movement. But not long after she did the soft glow in his shorts became brighter, and the movement began to take effect on him as he could no longer hide his soft moans and grunts as she too began to moan and arch her back... Sans prayed that she wouldn't wake up to find what she had been doing, he just hoped it would end soon and she fall back asleep next to him, then he could decide on what to do next whether it be to tell her or pretend like it didn't happen at all...

Meanwhile in the dream, Sans had picked up Frisk and had pinned her against the bathroom wall, as he continued to drive his thick member futher into her, she moan louder with each thrust. Her legs were wrapped around his hip bones and he was holding Frisk's arms high above her, he held all the control, normally Frisk would hate this but at the moment she was loving it, and with each thrust she could feel the knot in her pelvis get tighter and tighter. She could feel her partner's member grow and pulse inside her, she knew it would be over soon. And after just thinking that she felt him spray his load into her as they both came together.

They both fell to the floor in exhaustion, but after catching her breath Frisk got up, she could feel it as his insides slowly fell down her leg, "Guess we'll need another bath? Huh-", she was about to laugh but as she turned she found herself in a room of black... Where'd he go? Sans was there just a moment ago?

It was getting harder for Sans to keep it together as once again Frisk speed picked up, he knew it wouldn't be much longer now as he bit into a pillow so he wouldn't wake his brother, he didn't want to have to explain this to him... Frisk's legs began to tighten, he knew she was getting close as well, when suddenly he couldn't hold it any longer as he came in his shorts... Great...

Frisk sat there breathing heavily for a few minutes then got up and stood up in the middle of the room. Sans looked up at her and got up as well so he could change his shorts. Suddenly he saw her turn around, her eye was open now but he could tell she was still asleep since she was staring at nothing... Plus he tried the whole hand in her face thing and she didn't react...

Frisk still standing in the dark room began to look around... "Sans?", that's odd... Her voice doesn't hurt?... "Sans where'd you go!?!". But he didn't respond... She didn't move and kept looking around when something in the dark caught her eye... What was it?...

Sans watch from the bed as she looked around the room confused... He was really tired but wanted to make sure she got back into bed without hurting herself... Suddenly ahe looked scared and started backing away towards the door... No she wasn't scared... She was terrified... Frisk quickly ran out the door, this was no longer a dream... It was a Night Terror!

Sans ran after her only to see her run out the front door, "PAPYRUS! WAKE UP! WE HAVE AN EMERGENCY!!!", Sans screamed as he made his way to the front door that was left open. Papyrus walked out of his room with a groggy expression, "Hmmm What's Going On Brother?", Sans getting his slippers on, "Frisk just ran out the front door with only her PJ's! I'm pretty sure she's having a night terror!". At this Papyrus ran down and got his shoes on as his brother ran out the door towards the footprints that lead into the forest, 'DAMN WHY DID IT HAVE TO BE SNOWING TONIGHT OF ALL NIGHTS!'.

Frisk had saw the strange man of black with the broken face, she was scared of him... And when he spoke it sent cold shivers down her spine and gave her goose bumps... She couldn't even understand what he said but suddenly she was screaming and her and all she could do was run... She felt she had to get away from the clearly angry, confused, and possibly violent man and all she could do was run, and keep running, even when she could no longer hear him, even when it felt freezing, when she felt she was going to be sick, even when her limbs ached, even when her feet felt numb and bloody. It wasn't untill her legs finally gave that she stopped and at this point she was so tired and cold that she fell... Futher into the darkness...

Sans had lost the tracks not long after running after her, Papyrus had yelled that he'd go to inform Undyne of the situation and have her help with the search. It had been 30 minutes since then and it was just getting colder, as a Skeleton Sans was more resultant to the cold, but he knew a human wouldn't last long out here in what Frisk was wearing. He had to find her and fast, 'Ahg I should of just woken her up before! Now she's in danger!'. Not long after thinking this he tripped over something, he looked back and was shocked to see it was a leg covered in snow. He quickly got up and began to unbury Frisk, pulling her into his lap, she was still breathing but almost frozen stiff. He quickly called Papyrus to meet them at home, as he teleported to the house. He had to warm her up and get her out of those wet clothes before she got hypothermia, he quickly ran up stairs to the bathroom, Frisk still in his arms. He quickly turned on the hot water and got in with her fully clothed. He began rubbing Frisk's arms and legs to stimulate blood flow, as they were slowly being engulfed in the hot water, Frisk had started shivering like crazy. "S-S-S-Sans-s-s-s?", she was awake now, "Hey doll face, gave us all a scare there didn't ya?", "S-s-s-sorr-r-r-r-r-ry...", "Oh no dolly it wasn't your fault, just had a bad dream was all.".

Frisk kept apologizing until her voice ran horse and wouldn't respond to her anymore, it got to a point that even Sans couldn't tell who she was apologizing too... All he knew was that they'd need to start locking their front door better...
