Undertale One-Shots

{LEMON}-- Human!Sans x Reader: Puzzle

  "So, what did you say you needed me for?" You asked, leaning forward on the sentry desk where Sans usually worked.

  "I found this really cool puzzle and I wanted to show it to you." Sans replied.

  "Oh, cool. Where?" You asked, excitedly as you shot up from your bored position into one with glee and shining eyes.

  "It's in Snowdin." He said. "I didn't expect you to be so happy about it, though."

  "Alright, let's take one of your 'shortcuts.'" You said using finger quotes.

  "Yeah, whatever." He put his hands in his jacket pockets and walked away. You followed close behind him. And just like that, everything turned black. Everything smelled dirty.

  "Huh? It's dark." You mumbled. You waved your hands around trying to find what would be a light switch. Then you felt something briskly run across your skin, giving you goosebumps. "Eek! What was that?!" You squealed. "Sans! Where are you?!" You moved around blindly, with your hands outstretched. You started slightly panicking.

  And then you felt yourself being pushed by an unknown force until you hit a wall. A growing warmth spread across your back, but you still felt chills. "S-sans? Is th-that you?" You breathed.

  As if an answer, something pressed up against the nape of your neck, goosebumps formed on your skin again. And what had touched your neck before, came back again, this time, it was in the crook of your neck and moving to your shoulder. A hand had pulled at the neck of your sweater and stretched it past your shoulder, to expose bare skin.

  "S-sans!" You could barely go above a whisper. "This isn't a very funny joke."

  "Hmm?" He hummed through his nose. "Nobody said anything about a joke. Besides, I was bored. I wanted to know what you taste like."

  "Eh?! You're not going to eat me are you?!"

  "Not yet, I'm not." He said seductively.

  "B-but what about the puzzle?"

  Sans grabbed your waist and turned you around to face him. You found yourself staring into his glowing blue eyes. They looked hungry with lust.

  He leaned into your neck and kissed it again, lovingly, and then passionately, to hungrily. He moved up to your right ear and made love to it just the same. With each kiss and bite he did to your ear, he wore down its defenses, so that even the little things he did, like breathe and make sexy noises, were enough to send strong tingling sensations down your back.

  "Hey..." He whispered straight into your ear, causing your whole body to twitch.

  "Hhn?" You felt your face grow hot from feeling so vulnerable, especially from being made this way by someone, like Sans.

  "Do you wanna have a good time?" He said this sentence in a way that there are no words for. The way it rolled off his tongue. It might as well have been described as delicious.

  "G-good...time?" You asked, your body was visibly shaking. "Like hanging out with everyone at Grillby's?"

  "Hehe." He laughed. "Just how innocent are you, kid? I think you've done one too many resets."

  "...No....much better than that." He spoke, seductively as his hands wandered your body. He moved his head away from your neck. You found yourself once again, looking into his hungry eyes. "If that's the case, why don't I go ahead and teach you a couple things?"

  "Teach me..? What do you mean?" Your heart started pounding.

  "Follow my lead." He took off his jacket and tossed it aside, right behind it was the white shirt he wore under that. All for you to lay your eyes upon was his bare body.
