You had no place to stay. There was snow outside, so you could tell it was winter. You found a sign that said "Welcome to Snowdin." Wow. The town itself was a pun. You started walking down the road.
     Such a cozy little town. You were walking past a small log cabin when it's door swung open. Your eyes widen at the sight of who stepped out. "Sans!"
     He sees you and his eyes widen, too. "Y/N! Why ya' here, kid?" He calls.
    "Sans, I didn't know you lived here!" You were shivering now. Sans walks up to you, trudging through the snow. He takes your hand, pulling you to the house.
     Once inside, you gasp with wonder. It was small on the outside but huge on the inside. "You haven't met Papyrus, my older brother. He's obsessed with spaghetti. And puzzles." He adds. To you, he seemed excited and determined to show you everything in the house. Hm, sounds sweet. You wanted to meet him.
  "Where is he?"
  "He's with Undyne. She helps him train with 'Human Hunting'. But don't worry, he's not great at it, even if he does train." He tells you quickly.
   "That's alright. Is he like you?" You had to admit, you were scared of Sans a bit, he was a skeleton, after all.
   "No no no. He's taller, more slender, and yells when he's talking, even when he's whispering." Sans smiled at you, and you smile back.
   "When do you think he'll be back?"
   "Hm. An hour or two. Why?"
   "Wanted to meet him." He looks at you.
   "Ya' hungry, kid? Papyrus cooks spaghetti all the time, but his cooking isn't all that great. Wanna try Grillbyz?"   You were hungry, but you only nod your head. You've never heard of 'Grillbyz'.
   "Come, it's not far away. We can even take a shortcut, too. Take my hand." He held his hand out, and you instantly remember the first time you met him. You didn't trust him, although he did seem nice. You don't meet a short skeleton who tells sick puns everyday, after all.
   You take his hand and there was a light blue flash, and your vision became cloudy. You closed your eyes tightly and reopened them. You were in front of a building.
    "We're here!" Sans smiled, holding the door open for you. You both sit down at a table for two and a guy comes over.
   "Hey, Sans! New friend?" Sans nods.
   "Same as usual, Grillby." He says.
   "And you?" Grillby turned to you.
   "Um, I guess a burger..." You tell Grillby. As soon as Grillby left, Sans turns to you.
   "Hey, pass me that ketchup, kid." He points to the ketchup bottle that happened to be by your arm. You slide it over to him and he scoops it up. He had nothing to put it on, so why did he need it?
   He flipped open the lid, and chugged it down. You felt like puking. "You like ketchup, don't you Sans?" You laugh, seeing a ketchup mustache under his... Nose?
   He smiles. "Oh, I love ketchup. It's my favorite... Food?" You shake your head, giggling.
   "Sans, did you drink the ketchup again?" Grillby appears by your table. Sans eyes darted from left to right, then at Grillby quickly.
   "Maybe..." You heard Grillby sigh and Sans laugh. Poor guy... Must not get a lot of respect here... You thought. Grillby sats your guy's food down and shuffles away.
   You look at Sans's plate. Was that a hotdog? "What's that?" You ask him. Sans scoffed.
   "What do ya' think? It's a hotdog." You watch him take a bite.
   "Hey kiddo, you okay?" He looked at you worryingly. You nod your head. You didn't feel like eating anymore. It's not that he was disgusting, you jest felt like not eating.
   "Not hungry? Hey Grillby, put it on my tab! Let's go, Y/N." Sans gets up, with you following behind. Why is he doing this? I'm just wasting his time.
   You both walk silently the whole way to Sans's house.
   You felt like crying again. you were now on the couch. You heard Sans come in from the kitchen. "Hey Y/N. What was bothering you?" He brought it up. He just had to. You made a whimpering sound, and tears started swelling in your eyes. You managed to say "Nothing." But your voice was cracked. You felt a couple tears slide down, but you ignored them.
   People: LEMON ⚠️WARNING⚠️

Sans walks over to you, placing two boney fingers under your chin. He lifts your face to his, causing you to blush. He looks into your eyes with lust. He smiles when he sees your blushing face.
  He suddenly smashes his teeth onto your lips, and blush more. Was this a kiss? You close your eyes, finding yourself in pleasure. You wrap your arms around his neck.
   You felt something... Slippery slide into your mouth, intertwining with your tongue. You let out a pleasured moan, which Sans smirked at the sound. "S- Sans! Oh m- m- my-" you couldn't get much out.
  "What is it?" You both pause, catching your breaths.
   "We should take this somewhere private." You were gasping for air. He smirked at you, and teleported you both to his room.
   You felt him push you slowly to his bed, which was in the far left corner of the dark room. You were about to have sex with a guy you barely knew, a skeleton you barely knew.
  You lay down, your stomach facing Sans, and slowly gets on top of you, his hands slowly trailing up your sides, and under your shirt.
  You moan happily. Just the feeling made you long for Sans on you more. He nuzzles your neck, and starts biting and nipping gently at it.
  What could you do? You unzipped his hoodie and shoved your hands under his white tee, rubbing his ribs and spine slowly.
   His biting slowed, and you heard a few moans escape from him. You stop as you felt a tongue drag along your face and chest. Sans was staring at you intensely, smirking like a mad man. He moves a bit, trying to take your shirt off.
   You lift up your arms letting him. He pulls it off and tosses it behind him. There was a tint of light blue on his cheekbones, and then it was gone. His left eye turns blue and starts flashing yellow quickly.
   He was now drooling on your stomach. You knew what he wanted, so you nod. He shoves his hand down your shorts and you arch your back. He caresses your entrance, teasing you. You writhe below him, and he shoves a finger inside you.
   He comes in and out, making you groan with complete pleasure. You couldn't get enough. He adds in another finger, and another. He now had 3 fingers you, but you didn't care.
   You felt some kind of liquid come out of you, and Sans takes his hand out. His fingers were soaked, and you were quite embarrassed, until you see him licking his fingers, and looking at you seductively, his eyes half- lidded.
   "You taste pretty good for a human." He leans over you again, but it was your turn. He was about to kiss you, but you quickly flipped him over to where you were on top of him.
   "You've had all the fun. It's my turn." You started what you were doing earlier, rubbing his spine and ribs up and down slowly, then faster. He moaned a little, and a blush crept on his face.
  You were enjoying yourself when Sans moves his hands under your bra and starts fondling with your breasts. You were almost about to take charge again, when you both heard the front door open.
   "Shit." Sans gets up quickly, putting his hoodie back on. You pick your shirt up, putting it on and walk out with Sans.
   "Papyrus! Home already?" Sans was laughing nervously. Your eyes turned  to a tall, skinny skeleton.
   "A HUMAN!?" It yells loudly.

My very first lemon... How was it?
