Pulling My Heartstrings (Undertale Au Smut)

Error x Reader x Ink

I was sitting down on the couch, happily watching TV as I heard Ink and Error talking in the other room—though I wasn't really paying attention to what they were saying but I did nothing when the talking stopped.

I felt the couch move as someone sat beside me.

It was Error.

He leaned back, one arm around the back of the couch. I continued to watch the TV, though it was clear that he wanted my attention. I however was being a little shit and ignoring him-

Then Error wrapped his arm around me and pulled me into him, and I couldn't help the blush that spread across my face. He turned me so I was facing him, and I looked into his eyesockets, my blush darkening.

And then he kissed me.

I squeaked, startled by the sudden affection. I could feel the smirk he wore, and I found myself melting into the kiss, my face bright red. That color only got deeper as i could hear Ink clear his throat behind us,

"Oh come on Ruru, you couldn't have waited like a minute?" Ink said, pouting.

Error pulled away, a deep, rich chuckle rumbling in his ribcage, and he leaned back, his hand now resting on my thigh.

Ink pouted for a moment longer, before a sly smile formed on his face. He came and sat beside me, leaning into my neck and nuzzling. He trailed his tongue over my neck, sending shivers through me.

Errors hand then moved, sliding up my leg, and then slipped underneath the hem of my shirt, slowly moving upwards.

Ink bit my neck, causing me to gasp, and he took this opportunity to slip his tongue into my mouth. His hand went around me, resting on my lower back.

As Error moved his hand upwards, he cupped my breast, kneading it, his fingers rubbing my nipple, causing a moan to escape my lips. Ink deepened the kiss, pulling me closer to him.

Error, seeing how Ink was distracting me, used this opportunity to remove my pants, and he trailed a finger across my clothed folds. I moaned into Ink's mouth, and Error used this chance to slip his finger inside me.

I was moaning and squirming under their touch, and they were enjoying every second of it.

Ink pulled back, a thin strand of saliva connecting our mouths, and Error pulled his finger out, licking it off. Ink then pulled me onto his lap, my legs on either side of his waist, and he held my hips.

"You're so beautiful." He whispered, and he ground his erection against my clit. I whimpered, grinding against him.

Error was behind me, kissing my neck, his hands cupping my breasts, kneading them.

Ink lifted me, and I could feel his magic form beneath me, and I gasped when he pushed me down on it.

"Fuck! Oh god~" I cried out, feeling his cock penetrate my wet entrance.

"God damn it, you're so tight~" Ink growled, biting his teeth.

Error pulled his own cock out, and he pressed it to my ass, pushing into me.

"Aahhh~" I moaned, loving the feeling of being filled so much as I was sandwiched between the two.

Ink started moving first, thrusting up into me as Error gripped my hips and did the same.

My moans grew louder and more frequent, and my mind was a haze, drunk with lust and pleasure.

Ink gripped my hips harder, and he picked up his pace, his thrusts getting rougher, and I cried out when he hit a particular sweet spot, and my back arched.

Error bit down on my shoulder, and he growled, picking up his pace as well, and his fingers dug into my skin, no doubt leaving bruises.

The room was filled with the sounds of slapping bone, moans, and growls and grunts of pleasure.

"Ooh fuck~" Ink gasped out, his grip on me tightening.

"I'm so close~" I moaned, feeling the familiar heat pooling in my abdomen.

"I know sweetheart. Come for us, I want to see that beautiful face of yours~" Error growled in my ear, and with that I reached my climax, cumming hard, my back arching and my eyes rolling back.

Both of the skeletons were growling, their thrusts getting sloppy and they soon came as well, their magic spilling inside me.

They rode out their orgasm, before finally pulling out of me. Ink lifted me, his hands now gently holding me as he stood up.

"Let's go get you cleaned up." He said, and he carried me into the bathroom, setting me down in the bathtub.

"Y-you two could've warned me you planned to do that.." I huffed, looking at both of them.

Ink chuckled, and he started to fill the bath, while Error was cleaning me up, using a cloth to clean up the mess.

Once I was fully clean and we all got out, the three of us headed to our room. The bed was a mess, though it was rather comfortable.

Ink wrapped his arms around me, pressing his front against my back, his head buried in the crook of my neck. Error also was holding my hand as he laid on my other side.

It was comforting and warm. I found myself slowly drifting off, a small, content smile on my face.

"I love you two..." I mumbled, and I fell asleep, my body relaxing in their embrace.

They both smiled, and Ink gave me a gentle kiss on the neck, while Error gave my hand a light squeeze.

"I love you too." Ink murmured, and he snuggled into me.

"Sleep well, sweetheart." Error whispered, and the three of us drifted off into a peaceful sleep.
