Pulling My Heartstrings (Undertale Au Smut)

Error x Reader

I downed another bottle of alchohol, the taste burning my throat but the burn was better than than feeling absolutely empty.

"...Y/n, what did I tell you about drinking..?" I heard behind me, not even realizing that Error had been behind me. I didn't know when he came into the room but it wasn't the first time I've seen him look at me like this, as if I were going to shatter any moment and that annoyed me.

I didn't answer him.

He walked up to me, gently taking the bottle away from my hand before looking me in the eye.

I wanted to cry, to scream and to lash out but all I could do was look away.

Error sighed and pulled me into his arms.

He was always so warm, so comforting. It was a nice feeling and I couldn't help but lean into the touch.

We were like this for awhile, the silence in the air not uncomfortable, just nice.

Eventually I heard him talk again.

"I love you." He said softly. "You're the only person that could keep up with me and understand me... so please... don't try and shut me out..."

"I-I know... and I love you too.." I mumbled into his jacket.

He hummed and I could feel his phalanges run through my hair, his hands were gentle.

"I-if you need help, y-you can always come to me, Y/n..."

"Mm, I know..." I said and nuzzled closer.

"Do you... w-want me to help you...?"

I looked up at him.

"W-with what?"

His face was flushed a bright yellow, his hands gripping my hips.

"To... e-ease the pain...?"

It took me a moment to realize what he was talking about and a blush dusted my cheeks.

"I- uh, i-it's okay- you d-don't have t-"

"B-but I want to..." he cut me off. "I-I love you and I want to help you.. so... p-please...?"

"S-sure..."

With that, Error picked me up bridal style and carried me upstairs to his room, placing me gently on his bed.

"Are you sure about this?"

"I-if you are!"

Error took a deep breath and climbed onto the bed, sitting between my legs.

His phalanges trailed up and down my inner thigh.

"P-please be gentle.."

"O-of course, I wouldn't do a-anything you don't want me to, Y/n.."

His phalanges gently caressed my thighs before one of them brushed against my heat, a small gasp escaping my lips.

"I-is this o-okay..?" He asked.

"Y-yes, go on."

He nodded and pulled down my panties, his thumb brushing against my clit and a small moan slipped past my lips.

He continued rubbing circles around the bundle of nerves before moving down and pushing a finger into my core.

A shiver ran up my spine and he stopped his movements, looking at me worriedly.

"I-it's okay- please d-don't stop."

He nodded and started pumping the digit inside of me, curling his finger in a way that had me crying out in pleasure.

"I'm gonna add another finger, a-alright?"

"Please do-! A-ah~"

His middle finger pushed into me and his thumb was back on my clit, rubbing it slowly.

His fingers pumped inside of me, curling in just the right places.

"H-ha~ S-slow down-!"

He stopped, pulling his fingers out.

"A-am I h-hurting you..?"

"N-no, not at all! J-just a little sensitive..."

He nodded, continuing his movements.

His fingers thrust in and out, occasionally curling up to hit a spot that had me seeing stars.

"I'm g-gonna add another one."

"Okay R-Ruru.."

The third finger was pushed in and I groaned.

"I-is this a-alright...?"

"I-it's wonderful, E-Error- please go on-!"

His fingers began moving once again, my moans filling the air.

"A-ah~!"

My hands gripped the sheets, my hips rolling against his fingers.

"I-I think I'm close.."

He sped up, his thumb rubbing against my clit furiously.

"A-a-ah~! M-mhhmm!"

My vision went white and my back arched as I climaxed, my fluids coating his fingers.

I came down from my high and he pulled his fingers out.

I watched him as he put the fingers he had just used on me in his mouth, licking the digits clean.

"Y-you taste good.."

"D-don't say something like that.."

"Why not..? It's the truth.."

"J-just don't, okay..?"

"Alright, alright... now, d-do you need anything else..?"

"C-could you s-stay with me..?"

"Of course, I was a-about to ask that."

I moved over and he lied next to me, pulling me into his chest.

"You know, Y/n... you really do mean a lot to me... I don't want to see you like this again, okay..?"

"Mhm, I promise, I won't."

"Good."

He pressed a kiss to my cheek and I turned around to look at him.

"I love you..."

"I love you too, Y/n..."

Our lips connected and I closed my eyes, falling asleep in his arms.
