Pulling My Heartstrings (Undertale Au Smut)

Error x Reader

I ran through the woods with a pant, scared to look back as my sore legs continued on.

"Y/n~" I heard Errors voice call out for me and I shivered, hiding behind a tree but screaming as my soul suddenly tugged out my body being wrapped in blue strings.

He had a grin on his face and it only grew as he approached me.

He stood in front of me now, his red and yellow eyes staring down at me, his face showing a c razed yet loving expression.

I looked up at him, a glare on my face as he knelt down, his hand reaching for my cheek and I hissed, pulling my head back, my soul trying to pull me towards him as well.

He hummed, grabbing a hold of my soul, looking at it with a sadistic smile as he raised it in front of his face .

"E-error what are you- Ah~!" I moaned out suddenly as he licked my soul, causing me to shiver slightly.

His red and yellow eyes glanced at me, watching my reaction and I blushed.

His smile only grew as he placed my soul back inside my chest, his eye glowing bright blue as my body froze, him now having full control over my body.

He got closer, his glitched voice sending shivers down my spine.

"Now then darling.. What have I told you about running away?" He grinned darkly, and I was unable to move because of him have my soul covered.

"N-not too or I'd get punished.." I muttered softly.

"Good girl~" He cooed as he caressed my face, "Now what kind of punishment should I give you... Hm?"

I stayed quiet, watching him as he thought for a moment before grinning and turning me around so my back was to his chest.

He wrapped his arms around my waist, his hands gripping onto the hem of my pants, slowly tugging them down and I whimpered.

His hand trailed under my shirt, groping and pinching my breasts as I groaned, feeling something poking me from behind.

He hummed in my ear and I shivered, letting out a squeak as he slipped two fingers into my panties, playing with my clit, the other still groping and pinching my nipple.

My breath hitched and he chuckled, his tongue s licking the side of my neck, nipping at it before he began to suck on the skin.

My mind started getting fuzzy and I leaned back into him, a small moan leaving my mouth.

He smiled, removing his hands and I whimpered, wanting him to continue and being unable to hide it due to the magic .

But instead he pushed me against a tree, pressing his chest against my back and I whimpered, trying to move as my hands were still being controlled by his magic.

He chuckled in my ear, his hot breath against my skin and I shivered.

He pulled my panties down and I blushed, a moan escaping my mouth as I felt his bulge on my ass.

He hummed and grabbed my hips, his cock teasingly rubbing against my pussy.

He leaned close, his hand reaching around to grope one of my breasts as his tongue licked my ear, whispering in a deep tone,

"Beg for it~"

My mind was filled with lust and I was unable to resist the command.

I gasped out, trying to hold myself back.

"P-please fuck me!" I begged and he chuckled.

"Oh? And why should I give you what you want ? You've been naughty afterall " He grinned , his tongue s licking my neck again and I shivered.

I couldn't help myself, "Because you love me~ ..? "

He paused, and I knew I had said the right thing.

"Fuck" he muttered, "You're right"

I heard a sound of something tearing and he groaned, thrusting his dick into my wet pussy and I cried out.

" And you know what? That makes you mine. So I suppose I should " he growled, thrusting into me and I moaned, unable to move, only able to stand there and take his thrusts.

He groaned, gripping onto my hips and thrusting into me faster and deeper, his cock hitting the deepest parts of me and I moaned, tears of pleasure streaming down my cheeks.

"Fuck.. your tight.." he groaned, biting down on my neck and I cried out, leaning my head back.

"Error!" I screamed and he growled, his grip on me tightening and his thrusts becoming faster and harder.

"You belong to me, don't you understand? Only me" He growled in my ear and I moaned.

"O-only yours!" I screamed and he groaned, biting my neck again, licking and sucking on the wound.

I cried out as I reached my climax, his hand on my breast squeezing hard and he growled.

"Who said you could cum?" He questioned, continuing his fast thrusts, hitting my cervix hard and I moaned.

"I'm sorry! Please~!" I begged and he groaned, thrusting deep into me as he came inside.

I felt myself become warm and full, him holding me close and kissing the bite marks on my neck.

"Don't ever run from me again" He demanded and I nodded, leaning against him.

He kissed the side of my neck and sighed, releasing his magic, letting me finally move again.

I was panting, trying to catch my breath and he helped me pull my clothes back up, him doing the same and holding me in his arms as he got ready to take me back to the AntiVoid.
