Pulling My Heartstrings (Undertale Au Smut)

Ink x Reader

"I-ink!" I squeaked out, the artistic skeleton having snuck up behind me and wrapped his arms around my waist.

"Nice to see you too Y/n" He purred, nuzzling my neck and causing me to squeak again and blush deeply.

"I-ink, you k-know I can't focus when you do that" I whimpered as he chuckled and let go of me.

"Sorry, love, I just like hearing your adorable noises" He said, turning me around and kissing me, his teeth pressing gently into my lips. I hummed, enjoying the feeling before breaking the kiss.

"As much as I'd like to stay here and spend time with you, I should get back to what I was doing" I said with a small smile, watching his face fall.

"But it's the weekend, don't you want to spend some time with your boyfriend?" He asked, his face now close to mine and his voice low and seductive. I blushed and looked away slightly.

"Of course I do, but I need to-" I cut off as his hands found their way to my hips, grabbing them firmly. "Ah! I-Ink!"

"Come on, love, surely you can spend a few hours with me?" He asked, giving my ass a squeeze as his hand reached a little further back and pulling a soft moan from me. "That's my girl"

"You're not being fair, Ink" I whined, blushing even more and hiding my face in his shirt, the fabric smelling of paint and ink. He chuckled.

"What can I say, love? You bring out the worst in me" He joked, one hand coming up to run his fingers through my hair. I looked up at him, pouting a little.

"I'll make you a deal. If you spend a few hours with me today, I promise I won't bug you for the next two days. Does that sound fair?" He offered.

I thought for a moment, considering my options before sighing. "Fine. But only a few hours!"

"Yes, ma'am" Ink chuckled, giving me another quick peck on the lips before taking my hand and pulling me back into the living room, sitting on the couch and pulling me onto his lap.

I squealed softly, giggling a little as I settled myself in his lap. He smiled down at me, his eyelights shaped like a pink heart and a purple star.

"Comfy?" He asked, wrapping his arms around my waist. I hummed and nodded, resting my head against his chest and closing my eyes. I felt him place a small kiss on my head, smiling to myself.

We stayed like that for a few minutes before he spoke again. "I have an idea of how to pass the time"

"Hmm?" I hummed, not opening my eyes as he began rubbing my shoulders. I groaned softly, enjoying the feeling of his phalanges rubbing away the tension that had built up.

"You seemed tense earlier, so I thought I'd help you relax" He purred, moving down to tease the skin on my back.

"Mm, th-thank you" I managed to stutter out, melting into his touch.

He worked in silence for a few minutes before his hands moved lower, slipping under my shirt and massaging my breasts—causing me to open my eyes in surprise and squeak.

"I-Ink, what are you- Ah!" I was cut off by a moan as his thumbs found my nipples, flicking over them a few times.

"Sorry, love, but you're too cute. It's a sin to keep these amazing breasts to yourself" He purred, nipping at my neck.

I moaned, leaning back into him and feeling his cock form and press into my ass. "F-fuck, Inky~"

"I think that's the first time you've cursed in front of me" He mused, chuckling when I blushed and tried to hide my face.

"I-it's your fault for making me feel this way" I grumbled, gasping when he pinched my nipples, rolling them between his fingers.

"Well, why don't we do something about it then?" He purred, tugging my shirt off and leaving me exposed.

I blushed deeply, covering my chest with my arms.

"Don't be shy, love, I know how beautiful you are" Ink said, removing my arms from my chest.

"B-but" I started, but he hushed me, pressing a finger to my lips.

"No buts, your absolutely amazing" He said, leaning down and trailing kisses down my neck.

"Ahh" I moaned, arching my back into his touch.

His hands came up to grope and massage my breasts, his phalanges pinching and pulling at my nipples.

"Oh god, Ink" I moaned, reaching back and pulling him closer, grinding against him and feeling his erection grow harder.

"That's it, love, let me hear those beautiful noises" He whispered in my ear, nipping at the lobe.

"Ink, p-please" I whimpered, wanting more than his teasing touches.

"Please what, love?" He asked, smirking as he teased me.

"T-touch me, please" I begged, arching into his touch.

"Gladly" He said, reaching a hand down and teasing the hem of my pants, sliding his phalanges down the front of my underwear and running a finger up and down my slit.

"F-fuck" I gasped, feeling him tease my clit, sending sparks of pleasure through me.

"You're so wet already, love" He purred, dipping a finger inside me and making me moan.

"P-please, more" I begged, needing to feel him inside me.

"So eager, aren't we?" He chuckled, adding a second finger and pumping them in and out.
I moaned, gripping his arm and bucking my hips into his touch.

"Such a greedy girl, you want more, don't you?" He said, curling his fingers and hitting my g-spot, making me cry out in pleasure.

"Ah! P-please, Inky!" I cried, my mind clouded with lust.

He pulled his fingers out and spun me around, placing me on his lap with his back against the couch. He pulled me down into a kiss, his tongue dancing across mine.

I moaned into the kiss, grinding against his hard cock and making him groan.

"Fuck, love, you're so sexy" He growled, reaching down and unzipping his pants, pulling his cock free and rubbing the tip against my entrance.

"Ah! Ink, p-please" I moaned, needing him inside me.

"Patience, love, I'll give you what you want" He said, leaning up and capturing my lips in a heated kiss as he slowly pushed his length into me.

"Mmph" I moaned into the kiss, loving the feeling of him stretching me out.

"God, you're so tight" He groaned, bottoming out and waiting a moment to let me adjust.

"P-please, Inky, move" I whimpered, needing him to fuck me.

He grinned, holding my hips and moving me up and down his cock.

I cried out in pleasure, loving the feeling of him inside me.

"Oh fuck, yes" He moaned, speeding up his movements.

"Ah! O-oh god, Inky!" I cried out, throwing my head back in pleasure.

"That's it, love, keep crying out my name" He growled, his grip on my hips tightening as he fucked me hard and fast.

"Oh god, I'm c-close" I moaned, feeling my orgasm building.

"Then cum for me, love" He said, his voice strained.

"I-Inky!" I screamed as I came, clenching around him and sending him over the edge with me.

"Fuck, Y/n!" He moaned, burying himself deep inside me as he came.

I collapsed onto his chest, breathing heavily. He wrapped his arms around me, holding me close.

"Wow" I panted, resting my head on his chest.
"Yeah, wow" He agreed, chuckling and running a hand through my hair.

We sat like that for a while, enjoying each other's company.
