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

-9-

As a little gift, I made a part of smut in this 😏, you can skip it, I'll put a warning right before it, then tell you when it's over.

I woke up when I felt a small hand tug on my cheek. I opened my eyes to see it the was the middle of the night, and Jade was crying, shaking to wake me up. I picked her up, standing up, shushing her quietly, wiping her tears. I placed her on my lap when I sat back down on the bed, bouncing her gently as she slowly started smiling and giggling quietly. I smiled.
"There's that beautiful smile. Now, did you have a nightmare?" I asked. She nods.
"Uh-huh," she says softly. I stood, taking her back to her room.
"I'll read you a bedtime story and sleep beside you, okay? No monsters will get past me," I said. She giggled, nodding. I tucked both of us in bed, grabbing a children's book, opening it but she pushed it away.
"Wanna hear your story!" She said, smiling eagerly. I smiled.
"How about when I was in the underground?" I asked.
"Yush!" She said. I smiled.
"Okay... I had fallen on a bed of golden flowers, and when I came to, I was in a cave. I decided I needed to get back up to the surface, so I started walking. I came upon a golden flower, who talked! He told me his name was Flowey. He was a sweet flower. He told me about my SOUL, which is right here, where your heart is. It looks like a heart too! Anyway, a lady, her name was Toriel, she came, helping me around the RUINS. She cared for me. She's like a mother to me. But, I had to leave her to get out of the UNDERGROUND. When I left, there was snow everywhere on the ground. I came upon two skeletons, Sans and Papyrus. Papyrus loved puzzles, so he made some puzzles that didn't really work, but it was still fun. Sans, now Sans, he was the funniest guy I've ever met. He made a skele-TONs of skeleton puns, and it cheered me up. I ended up falling for the pun master, though I didn't realize it at the start. Soon, both of the skeletons guided me. I made more friends, Undyne, Alphyis, then lastly, Asgore. Though, now, I had to fight. I didn't want to, I didn't want to hurt anyone down there, they already suffered. But, before we could start the fight, all of my friends came in, telling us not to fight. Toriel and Sans joked a bit. But, all happy endings had to have a painful moments. Flowey, he turned bad. He tried to... hurt my friends. I stopped him and broke the barrier, but now, I only have half a SOUL," I said, making my SOUL show itself, letting her see the broken SOUL. She looked shocked and in awe, touching my SOUL gently. It hurt slightly, but I didn't mind. I placed it back inside.
"Kitty, why aren't you gone like Mommy then?" She asked.
"A miracle, Flowey used his SOUL and only took half of mine to open the barrier with the other SOULS. We left, we were happy. Sans and I were together, but... you know about my dad? How he, left us?... it broke me. But Sans lifted me up, put me back together," I said.
"Prince Charming!" She exclaimed. I chuckled.
"Yes, he is my prince charming. And I have my happily ever after," I said, kissing her forehead. She giggled, cuddling up to me. I turned off the light and held her close, hearing her even, steady breaths. No nightmares, good.

I held her until morning, watching over her. She woke up, smiling at me.
"Kitty! Nu neetmars," she said, trying to say nightmares. I smiled.
"That's good, wanna go make pancakes with me?" I asked. She bolts out of bed, nodding excitedly. I chuckled, chasing her down the hall, picking her up and sliding down the rail, into the kitchen. No one was awake, seeing as it was 5 am. We, in our pajamas, cooked dozens of pancakes for everyone, flour covering us from our small food fight. We set the tables and rang the bells for everyone to wake up for breakfast. Everyone came down, groaning but perked up at the pancakes, grinning at the two girls covered in flour and on pajamas, while everyone looked neat and tidy.
"Why, don't you look delicious?" Sans whispered in my ear, grinning. My face heated up, contrasting with the white flour covering me.
"It's flour, not sugar," I pointed out.
"Maybe I like flour?" He asked, chuckling. I laughed softly. I looked at everyone, who ate all their pancakes happily, chatting. Jade was sitting in Toriel's lap, being spoon-fed her pancakes.
"You know, Jade said your name last night, in the bath. She asked where you were. She also had a nightmare, I told her the stories of the UNDERGROUND, she loved them. She said you were my prince charming," I said, grinning. He kissed me deeply, only pulling apart when Toriel cleared her throat.
"And you are my delicious princess, Kitten," he said. I blushed madly, and he looked victorious from my face. He picked me up, taking me upstairs.
"Toriel, give Jade a bath please!" I called, knowing where this is going. She smiled and nodded.

Smutty smut smut now

Sans carried me to my room, pinning me to the wall, his blue eye appeared and his tongue licked all the flour of my neck and chest as my body shivered in delight, since that's only where Jade hit me with flour.

His licking soon turned into biting, and delightful shivers turned into pleasurable ones as tiny moans escaped me. He soon pushed me onto the bed, taking the nightgown I wore off and his teeth latched onto my breasts, seeming happy at every moan that slipped out of my mouth.

He looked at my whole body like it was the first time he saw it, drinking in the sight of me squirming in pleasure, gripping the railing above me. He thrusted hard, happy with my reaction as he did, hearing my cries of pleasure, moaning his name which made him go only faster and harder until our climaxes.

Smutty smut smut is over.

He picked me up, caring me to the bathroom and setting me on the counter, turning on the shower and setting me down under the water, getting in as well, washing my hair and body, letting me relax against his hands, closing my eyes.
"Come on, lets get you dried off, Kitten," he said, grinning. I felt my cheeks burn bright as we stepped out from the shower and he turned the water off, grabbing a towel and wrapping it around me, picking me up and setting me on my bed and filly drying me off.

I put on my usual clothes, calling Papyrus over so we could pick up their new clothes. Zoey made more outfits for them as well, so I'll pay her a good tip. I strapped my PK like usual, deciding to take my other pistol, a hi-power Hungarian FEG 9mm. I strapped that to my other thigh and we set off to pick up the clothes.

We got there, walking in and Zoey set all the clothes into a medium sized cardboard box, which I handed to Papyrus with a smile. He could see over the box perfectly fine. I told them to wait as I walked out of the shop, hearing a few gunshots. The boys headed, ducking under cover. I took out both pistols, shooting two guys who were next to each other and pinning one guy down, grinning wickedly and giggling.
"Silly, how many of you will come after me before you understand, you can't kill me?" I asked sickly sweet. I knew Sans and Papyrus could hear the deathly sweet voice, hearing my crazed laughter as I shot the man before he could speak, blood splattering on my clothes. I got up, closing my eyes and calming myself down. I put my guns away and walked back into the shot. Zoey hugged me.
"That was so badass! You're the coolest ever! I'm the luckiest girl in the world to have you as a friend!" She squealed, her eyes flashing with craziness, she may be crazy, but she was still a good friend. I smiled.
"Thanks Zoe, here's the money for everything and a 30% tip," I said, handing her the money. She nods, taking it. Sans looked at Zoey with hatred. I guess it was from the eyes again. Papyrus looked confused.
"HUMAN, WHY IS THERE BLOOD ON YOU?" Papyrus asked. Oh god, he was too innocent for this.
"Uh... Papy, I'll tell you later, okay?" I said. He nods, picking the box up as we walked home.
