Mafia in the Underworld? {Mafiatale Undertale FanFic} (Sans x OC)

-14-

We got home, Litho and I a bit dizzy but we were okay. I took Litho upstairs, tucking him in, seeing as it was around midnight. I changed into a white crop top and black leggings, letting my stitches breath. I looked at the clean stitching, dragging my finger over it and feeling the sharp pain but it wasn't that bad. I went downstairs, curious as to where Sans went, but didn't worry too much.

I grabbed a glass of water, drinking it and taking the pills so my stitches don't get infected, yawning but wasn't tired enough. I heard footsteps, Sans.
"Hey," I said, smiling and turning around. It wasn't Sans...it looked like Sans, but he had red eyes, looking pissy and wearing a black hoodie with a red shirt under it with black jeans. I stepped back, grabbing a kitchen knife to arm myself. He tsked, using magic to knock the knife out of my hands.
"I'm looking for Sans," he growled, walking closer to me. I backed up into a wall, gritting my teeth.
"He's somewhere in the house," I said.
"Take me to him," he growled.
"Why?" I questioned.
"Just do it, pet!" He snapped. I growled, stomping off with him trailing behind me. I open the door to my bedroom, he's not there. I checked on Litho to see Litho still asleep, but no Sans. The basement...

I walked down to the cellar, clenching my fists. The cells had some men we torture to get info, killing them when done. They all shouted at me, growling like feral dogs, some whistling at my attire. I gave them all death glare and they jumped away.
"Shut up you filthy creatures," I growled. They all obeyed, staying in their beds. I walked to a man in a cell, one that always gave me info. I kneeled down, wincing.
"Did a skeleton, look like this guy over here pass, Jax?" I asked. He walked out of the darkness, smiling.
"Yes, he went into the torture chamber, m'lady," he said.
"Thank you," I said, standing and hissing in pain.
"Did something happen?" He asked.
"Just a simple gunshot wound, I'll be okay," I said. He nods, disappearing into the darkness again. I walked into the torture chamber to see Sans looking at all the weapons, looking curious and angry.
"Sans," the weird version of Sans said. He turned, looking at us in surprise.
"Fell? What are you doing here?" Sans questioned, walking up to us.
"I don't know, I just appeared here. I asked around, found out you were staying here and came here," he said, crossing his arms.
"Explain please," I said, crossing my arms.
"I come from another timeline, another universe where something's are a lot different in the underground, pet," he said, glancing at my body.
"Don't call her that," Sans growled. Fell smirked, suddenly, a collar was around my neck, he was holding a gold chain that was attached, pulling me close and I hissed in pain, my side flaring.
"What? She was nice enough to help me find you, though she isn't obedient enough," Fell said, looking down at me with lust in his eyes. My heart was confused, yearning for both, but my brain knew they were two different people, shutting down my heart's opinion.

I reached up, grabbing the chain to try and get it off. Sans held up his hand and a bone cut through the  chain and I dropped to the ground, taking the collar off and throwing it on the ground as it faded away. I moved behind Sans quickly, who looked pissed.
"She is mine, not yours Fell," he growled.
"In my world, she loves the collar and chain, and I can tell in this world she still likes it. Too bad she's loyal," Fell said, smirking, his gold tooth shining.
"I would never like a collar, I'm not a pet," I growled.
"I could see it in your eyes, you're a kinky one. You just won't tell Sansy over here," he smirked.
"So? I can deal without kinky shit," I said, crossing my arms and glaring.
"Maybe," Fell said, smirking. Sans was looking between the two of us, confused.
"What? Kinky?" Sans asked. I went beet red.
"Fell will explain it to you," I mumbled.
"Kinky is when someone likes something that's a bit different while in the 'bone zone'. Your pet over here, loves collars in bed and told orders, even if she denies it," Fell said, smirking. I grabbed a knife, throwing it at him, but he just dodged it, my face looked like a tomato.
"Don't add that part!" I shouted, loud enough for the prisoners to get curious.
"So I'm not lying?" He questioned. I growled, throwing another knife and he swatted it away.
"I never said that!" I snapped.
"Listen, pet, throw another knife and I'm gonna have a great time," he said smirking. Sans growled, knowing what he was talking about and pulling me behind him.
"Anyway, to get back on the correct topic... will you be staying here?" Sans asked, glaring.
"Don't got anywhere else to stay," he said. Sans sighed.
"Fine, I'll go set up a room, you two chat," I said, starting to walk off, only for the collar to appear on my neck and Fell pulled the chain, making me stumble back. I growled, throwing the collar off and stomping away, hearing the laughter from I guessed Fell.

I went upstairs, checking on Litho to see him awake and crying black tears, confirming that was his power color. I picked him up.
"Did you have a nightmare, Litho?" I asked. He nodded, whimpering.
"Mhm," he mumbled.
"Do you want to go back to sleep?" I asked.
"No mommy," he said.
"Okay Litho, I have to set up a room for one of Daddy's.. brothers, he'll be staying for awhile," I said. He nods. I put him down and he follows behind me like a lost puppy. I grab black sheets and a red blanket, seeing that's all we had in dark colors, knowing Fell wouldn't like bright colors, walking into a plain room, making the bed as Litho watched, humming along as I sang.

Fell and Sans walked into the room and I stopped singing.
"Fell, this is Litho, my son. Litho, this is Daddy's brother, Fell," I introduced. Litho walked up, smiling.
"Hi Uncle Fell!" Litho said. Fell tried to seem mad, but I can tell he already likes Litho. I pick up Litho, grinning.
"Alright Litho, I think you need to go back to bed, I'll make pancakes for everyone in the morning," I said.
"Yay! Pancakes!" Litho cheered and I smiled, taking him to his room, tucking him in as Sans and Fell followed. I kissed Litho's boney forehead before closing the door behind me.
"Cute kid," Fell said, his arms crossed.
"I found him in the Underground when I visited it, a few days ago. I basically adopted him and he's already family," I said, smiling fondly.
"He looks like Sans and Paps," he said. I nod.
"I can see that. He's got Sans laziness unless there's food, and Papy's cheerfulness," I commented. Sans grins, kissing me gently as Fell faked gagged, which I flipped him off. I heard a knock at the front door and I looked at it. It's two am, who's knocking. I grabbed my PK, walking to the door and peeking through the peephole, seeing a tiny blue version of Sans and a lazy looking Papyrus. I blinked a couple times before opening the door, putting away the gun.
"Sup," Papyrus said, his hands in his orange hoodies pockets.
"Human! Human! Human!" The tiny Sans said, hugging me. He was adorable and innocent, even with his face in between my breasts. I wrapped my arms around him so he wouldn't fall to the ground.
"Are you looking for Sans?" I questioned. Papyrus nodded. Sans and Fell walked down. Fell grinned at the new Papyrus and tiny Sans hugged real Sans.
"Kitten, this is blueberry and that's just Papyrus, choose what you call him," Sans said. Blueberry did look like an adorable blueberry.
"Kitten? That's her name?" Fell questioned, almost laughing.
"My name's Lazara, I go by Lil, he calls me Lil Kitten," I explained. New Papyrus patted my head.
"Cool," he said. Oh god he's like Sans.
"I have to deal with lazy people," I sweat dropped, sighing.
"Human, I'm hungry," Blueberry said. I grabbed his hand and took him to the kitchen with everyone following. I yawned as I cooked grilled cheese for everyone, tired. I placed plates in front of everyone and New Papyrus raised an eyebrow.
"What's wrong with your stomach?" He asked.
"I got shot... yesterday? I think it was yesterday," I said. Sans remembered something.
"God dammit Kitten, you're supposed to stay in bed. For fucks sake I forgot!" Sans exclaimed.
"I'm fine Sans, they haven't ripped and they only hurt if I stretch," I said. He didn't look convinced, making me sit down at the table with everyone else. I rolled my eyes, puffing my cheeks out.
"Are you sure they don't hurt? No bleeding? Nothing?" He questioned, lifting up my crop top higher to look at the stitches. I smacked his hand away, beet red.
"For the love of God Sans, Blueberry is innocent!" I growled. Sans frowned.
"So?" He questioned.
"I'd rather not ruin it, and I'd rather not flash the others," I said. Fell and New Papyrus seemed to sigh in disappointment and I glared. Blueberry was confused, continuing to eat.

I had to make two more rooms, exhausting me even more before going to bed with Sans. I changed into my pajamas and went to lay down when Sans said something that made me almost die from embarrassment.
"By the way, was what Fell true about the collar thing?" He asked. I choked on my own saliva, coughing hard.
"Jesus fucking Christ, forget about that, it's nothing important," I said after coughing.
"I still wanna know," he said.
"Of c-course n-not!" I stuttered, beet red. He raised an eyebrow bone.
"You're a terrible liar," he said. I just laid down, facing away from him, only for him to pull me close.
"You know, in the other timelines, you were never kinky," he whispered.
"Because I probably never said anything," I mumbled, hiding my face in a pillow.
"True, and you're still the same submissive little kitten," he grinned, his breath fanning my neck as I shivered in pleasure. Before anything else, he turned away and fell asleep, making me sexually frustrated again before falling asleep as well.
