Just One Night

Interruptions

After the issue of Mettaton and Papyrus' newfound relationship had been handled, the two of the them went on to let their viewers and fans know just what went down in their lives. However, they never broadcasted a single fight, or any personal conversations. As far as the public eye was aware, they just announced their plans to date, and if they were lucky, the fans would get to see a few cute pictures from their excursions.

Mettaton had acted very mature lately, no longer focusing solely on himself, but giving Papyrus his undivided love and attention. Papyrus in turn stood by his side after long days at work and made him laugh like no other, giving his all to loving the robotic monster he had fallen in love with. His determined spirit always brightening the young robot's heart, especially after long days of putting on a happy and energetic persona for the monster populace.

It had only been about a month since they were official, and things were going off without a hitch. Their friends had readily accepted their newfound relationship, even going as far as sending them on vacation up on the surface.

It had taken quite a bit of persuasion, seeing as the two monsters were quite fond of their respective jobs, but when Undyne declared she would no longer train with him had he not gone, Papyrus' mind was made up. Frisk had even nudged Mettaton and told him a few choice scenarios that had him close to short circuiting, with the darkest purple blush covering his entire face. He even whacked her on the head with a rolled up newspaper, like she was an animal, which for a moment he considered she was since her ideas were so.. animalistic. She merely laughed and pushed them out the door, calling out well wishes to the happy couple.

Her boyfriend had finally made peace with the fact that Mettaton was a good fit for his goofball of a brother, but that didn't mean he still wouldn't call him a tin can at any chance given, he had a reputation to uphold.

As for the human and skeleton pair, they were happily adjusted to the new lives they led. Frisk had become the spokesperson for monsters everywhere, standing up to corporations aboveground that discriminated against her monster friends. She became a beacon of hope for Underground, hoping that one day they would achieve true peace from the simple minded humans. Sans supported her in any way possible, taking her on trips to the surface, actively helping her with the paperwork she received from both monsters and humans alike, and even going as far as attending meetings with her.

She couldn't have been more happy, but at times she worried for her monster. On the days where they weren't together, his work seemed to be more and more demanding of him. He would come home late some night with dark rings under his eye sockets and the occasional flickering blue and gold eye only furthering her worries.

On those nights she would prepare him a nice bath, make his favorite meal, hotdogs both cut up and whole slathered in ketchup until they were practically dripping, and would give him kisses and cuddles while they cuddled together under the sheets. He would often awake in the middle of the night in a momentary panic before she held him close, humming softly to calm his frazzled nerves.

She had tried on many occasions to figure out what exactly he did for a living, but he would always evade the question or just give her a shake of his head. Her curiosity was peaked, but one day when she had gotten too close to finding out the truth, he had told her that it was something he wasn't proud of, and that if she interfered, it would likely be the end of their relationship. Upon hearing that, her determination faltered, her heart sank, and she begrudgingly agreed to drop the subject, although a part of her would always stay wondering just what was so secretive about his work. Was it that dangerous that he had to threaten their relationship? Would he walk out the door one day and never come home? It left her worrying daily, praying that he would come home safe and sound.

Sans had never wanted to pull that type of card on her, but she just couldn't find out the truth. It would shatter her image of him and she would be in far more danger than she already was just by being with him. It ate at him that he had to keep secrets from her, but he wouldn't dare jeopardize her safety or risk the judgement that would ensue once she discovered what exactly he did prowling the streets at night.

It was an exceptionally cold evening that found the pair bundled up on the couch under a thick blanket watching their favorite anime: Mew Mew kissy cutie. Frisk curled up into Sans' side sighing contentedly. His bony arm circled around her waist rubbing small circles on the skin just below her baggy t-shirt. She smiled happily before leaning up to kiss his cheek, but before she could he turned in time to peck her lips softly.

Her face lit up in a soft blush before she playfully swatted at his arm.

"No fair! You cheated." She huffed playfully pouting

"I didn't cheat, you just have poor aim!" He laughed softly.

"Do not!" She cried out in mock anger.

"Do too!" He retorted.

"Do not!" She argued a bit louder.

"Do too! Bleahhhhhhh!" He declared sticking out his softly glowing tongue.

He didn't even see it coming when she leaned forward and sucked his tongue into her mouth. He only gasped in shock, his eyes going wide for a second. Her lips twitched upward in a small smile before continuing her heated battle for dominance. Her eyes drifted shut as she climbed onto his lap, resting her hands lightly on his ribs. He didn't know what had gotten into her but he certainly wasn't going to stop her.

Frisk rubbed her small hands across the rough sensation of his bones, pulling back lightly to giggle at his lust filled expression and the way his breaths were coming in soft pants. She leaned forward to run her tongue along the bones of his neck simultaneously continuing the delightful torture of playing with his ribs, which she found to be extremely ticklish and highly sensitive. Lower and lower she went still until she reached his throbbing member, his delighted gasp registering faintly as she stroked upwards gently. With a triumphant smirk, she cupped him through his gym shorts and pumped agonizingly slow for his liking.

With a soft growl, he flipped their positions lying her back against the couch while he proceeded to invade her mouth. His possessive hunger sending wonderful shivers throughout her body. While he explored her mouth, tasting and savoring her sweetness, his bony hands cupped her breasts in a rough manner. She moaned at his rough treatment before sliding her hand back down to his front, continuing to play with him while he lifted her shirt to greedily suckle on her hardened peak. His other bony hand slid past her sweatpants, past her panties until she cried out at the soft pinch of her clit.

Not wanting to be outdone, she slid her hand inside his pants eagerly stroking his shaft all the way to the head. She swirled lightly on his head noting the slow shiver that passed between them. They kept up their sensual dance until they were both readily reaching their climax. With their last remaining inhibitions gone, they came together screaming one another's names.

Just when the door opened to reveal a seriously purple Mettaton and a scarlet headed Papyrus.

"Uh... welcome home?"
