Undertale Smut

US!Papyrus x Reader

(I'm sorry for the delay guys x__x I just had writers block and I finally came up with something. Enjoy!)

It has been a while since you fell down a hole while exploring a mountain. You met a lot of things that were quite odd. The first one was a motherly goat woman, then when you reached Snowdin, you met two skeletons, Sans and Papyrus. Papyrus was the pretty chill one, and Sans was the one that wanted to capture you for some odd reason.

Oddly enough, you grew on them. You became friends, actually. But something odd happened. They both had feelings for you.

You had chosen Sans. You thought his personality was really cute, and you had feelings for him as well. But Papyrus was different after you chose Sans. He seemed a little... sadder than usual.

You thought he was probably jealous of Sans. They both had feelings for you, after all. You were in a bizarre love triangle with two skeletons.

You actually felt bad for him. You never wanted a three-way relationship, but you finally decided to cheer him up.

Papyrus was in his room. You knocked on the door and it opened. "Oh, (Y/N), it's you." He said in a sad tone. You let out a sigh. You've never seen him this depressed.

"I just wanted to tell you that I was kind of depressed when I was on the surface. Besides, I know something that will cheer you up." You laid him on his bed beside you. "Just don't tell Sans, okay?"

You sat on his groin and started rubbing your crotch against his cock. He let out a soft moan. He was blushing bright orange, and another orange glow soon formed in his crotch. You took off his pants and stroked his now erect dick. He gasped as his cheekbones glowed an even brighter orange.

"S-stop teasing me, just... AH!"

Your lips wrapped around his cock as you began to suck. He covered his face with his arm as he moaned loudly. You started to suck faster until you finally stopped.

"Don't worry Paps, we're only getting started."

You pulled off your pants and rubbed your entrance against his cock. Papyrus uncovered his face and grabbed you by the shoulders. Papyrus pinned you down where he was laying. "It's my turn now." Papyrus rubbed his cock against your entrance and thrust into you. You let out a loud yelp.

You did this with Sans before, but he was never this rough. It was all new now. It hurt, but it felt good. You moaned out.

Papyrus grunted and started to thrust faster. You were getting closer to your climax. "Ahh... (Y/N), you're so tight!" You were so close. Just a little more...

You finally released as your walls tightened around Papyrus' cock. He seemed to be close too. Then he finally let out a loud moan.

"Nngh... Ahh... I'm so close... I'm cumming! GAH!"

He thrusted into you one last time until his cum shot inside of you. He panted heavily. He finally pulled out of you.

"That was really fun..." You said before you fell into a deep sleep.
