It's All Too Much!!! (all Sans AUs x Female!Reader Lemons)

Classic!Sans X Reader

You had freed the monsters from the underground a few years ago. And today was Papyrus's 17th birthday. You and Sans knowing him best and being that you were both 21, you were in charge of setting up the party. It didn't take you very long to set up the party. Grillby was kind enough to let you use his establishment to throw the birthday bash. Napstablook and Metaton were the DJs and everyone was out buying presents. "finally done" you huffed and leaned against the bar next to Sans. He had his eyes closed and his hands in his pockets and appeared to be asleep until he opened an eye to look at you. 'god, she's so pretty... If only i had the... Guts... To tell her how i feel' he thought to himself, his white pupils beginning to trail his line of sight down your body. "uh,... Sans, my eyes are up here" you grinned nervously. 'what's with him? He's been acting really strange lately... I hope he's not sick or something... Or maybe his nightmares are finally getting to him... Oh well... Regardless, I'm gonna ask if i can spend the night to make sure he's okay' you thought to yourself. "uh... Hey, Sans?" you smiled softly at him. "hm? " he hummed, seeming to be in a daze again. "can i stay at your house tonight? My place is getting a kinda... bonely vibe to it lately." you lied. "eh, sure... Why not. " he flashed his signature cheesy smile. Grillby walked out from the back room after taking inventory. "good job on the decorations, you two!" he spoke softly. "aww. Thanks, Grillbs. " Sans smiled at him. "while doing an inventory check, i found that there are two bottles of alcohol more than what there should be. Take them... You've earned it." Grillby seemed to smile back. He set two large bottles on the bar next to you. One was a hard liquor and the other was a more fruity drink fit for someone of your stature. Sans looked at the liquor before popping it open and taking a long drink of it. You fiddled with the lid, unable to open it. "here... Need help?" he questioned before opening it for you. You smiled sweetly at him before taking a small sip of your bottle. Before too long, you and Sans had drained your bottles of their contents. The party was much like any other birthday party. Before too long, the alcohol hit your systems. You both stumbled around the party, slurring puns and saying random nonsense. Papyrus walked you both home at the end of the night. He put Sans up in his room and settled you on the couch before going to his own room and going to bed. You lay there for what felt like hours listening to Sans annoying his brother to the point that Papyrus went to go see if Undyne would let him stay the night at her house, leaving you and Sans there alone. Sans giggled and flopped down next to you on the couch. "h-heeeey Sansy... "you slurred, making him look over at you. "wus wrong, man... You been actin really weiiiiird and stuff. " you slurred some more. "y/n... I've always thought... You was cute an stuff... An i jus wanna say... Tha i really like you" Sans giggled and fell over. "wai, you mean it?" you asked, drooling slightly. "yahuh... You pretty, an funny, an i wanna fuck you like an animal" Sans slobbered a bit. You blushed like mad. "s-sh-shhhhh-*hic*shhhh...don tell y/n...isa secret " he cackled, leaning close before falling off the couch. "paint me like one of your French girls " Sans giggled on the floor. "nuuu Sans, i save yuuu" you slurred before falling off the couch and landing in an awkward position on top of him. "hey there, gorgeous " he breathed making your core wet with excitement. Hormones were getting the better of both of you at this point. He flipped you over so he was on top and began trailing sloppy kisses all over your neck until he made you purr by finding your sweet spot. He showed no mercy, licking and nipping at it before biting down roughly, leaving his mark. "you're mine" he growled in your ear, sending shivers down your spine as you felt your sins crawling on your back. You began tugging at his jacket, silently begging him to take it off. "no, you first" he huffed before literally tearing your party dress off. His smile widened as he trailed more sloppy kisses from your new hickey, to your collarbone to the top of your breast before unclapsing your bra and throwing it into a corner. He looked up at you before teasingly sticking his glowing blue tongue out. 'god damn, who knew a skeleton could be so sexy' you thought to yourself as he swirled his tongue around one of your sensitive nipples before nipping at it. He coppied these motions with his boney fingers on the other nipple. "ooooo, Saaaaaaans" you moaned softly. He growled and rubbed the growing bulge in his shorts against your womanhood, which had soaked through your panties, the scent driving Sans crazy. He took off his jacket and shirt seductively. He stood and sat on the couch. "i think you know what i want" he purred. You crawled over to him and looked timidly at the bulge in his shorts. "go on" he urged huskily. You grabbed the elastic of his shorts and tugged down, his ectoplasmic erection springing out. It was by no means small. 9inches long and 3inches wide... You didn't know if it would fit. You wrapped a hand. Around it and noticed it was leaking some precum. You gingerly licked the precum off, hearing Sans gasp as you took his tip in your mouth. You swirled your tongue around it and sucked hard on it. you looked up at Sans before grabbling his soul. You began massaging his soul as you took him balls deep, gagging slightly before beginning to bob your head up and down his shaft. You looked up at him again. He was sweating and panting and groaning like crazy. You pressed a finger against the center of his soul and heard him cry out your name in pure ecstasy. His cock twitched and swelled. He grabbed the back of your head and thrusted in as far as he could before releasing a load. He pulled out and it was still hard. "get on your back, y/n" he sighed with his tongue lolling out. You got up on the couch and laid down. Sans grabbed your legs and put one over each shoulder. You felt his member poking at your entrance through your panties which he waisted no time in tearing off of you. He thrusted a short ways in before he laughed. "you're a virgin, aren't you, y/n?" he stated more than asked. "don't worry, I'll be gentle" he purred before quickly thrusting in. Blood trickled from you as you whimpered in pain. He held you close, giving you lots of kisses and whispering sweet nothings while he waited for you to give him the okay to move again. After a while you moved your hips, letting out a soft moan. He gently thrusted deep into you, keeping a slow pace. He reached his hands around your legs, using one hand to rub your clit and the other to massage one of your breasts, using his tongue and teeth to give the other breast some attention. You were a moaning, squirming mess, begging him to go harder and faster. Your moaning became desperate as you felt a knot forming in the pit of your stomach. "OH, SANS! I'M SO CLOSE! I'M SO CLOSE! KEEP GOING!!! " you cried out. Sans let out a ferral growl as he slammed into you, sending you both over the edge. "SANS!!! I'M GONNA C-CUM!!!" you whined pathetically. "ooooh, cum for me, y/n... Cum for daddy" he purred in response. You screamed his name as you rode out your climax, Sans soon joining you on cloud nine. Sans smiled before snapping his fingers, instantly cleaning up the clothes, cum, sweat, and the smell of sex, and teleporting you both into his bed. He pulled you close to him and threw his blanket over both of you before planting a gentle kiss on your lips. "i love you, y/n" he sighed before falling asleep with you cuddled up in his arms.
