Pulling My Heartstrings (Undertale Au Smut)

Reaper x God!Reader

I sat on our bed, Reaper off at work again but should be home soon... I was rather deep in my thoughts, finding it kinda ironic that that I, the Goddess of Hope, felt so... glass half empty. It wasn't the fact he was at work or that he had been working late most of the week. No, I could handle being home alone for a few hours. I was a god, one that didn't need a babysitter.

But the fact was...

"You know, you look like your about to blow a fuse, is something up?" Reapers voice rang out, making me jump a bit. How long had I been lost in my thoughts? "What has you so pissed?" He chuckled, leaning over to kiss my forehead.

"Oh nothing, just the normal stuff." I shrugged, trying to seem cool, calm and collected. Reaper didn't look convinced, instead raising a brow as he stood back up, taking off his cloak and leaving him in the casual clothes underneath.

"Alright, if you say so.." He said and I started to get up,

"I'll be fine after a shower, don't worry. I'm sure my emotions are all over the place because of hormones or something. I'll see you in a bit, kay babe?" I said and Reaper nodded, not looking all too convinced still.

"Okay, well I'll get dinner going then." He said and I nodded, quickly heading off to the bathroom. I shut the door and let out a sigh, running a hand through my hair as I stripped.

Reaper had been working late a lot the past week or so, and honestly, I was feeling a bit... neglected. I shook my head and headed into the shower, turning the water on hot. As I let the hot water soothe me, I couldn't help the thoughts in the back of my mind telling me I wasn't good enough anymore. The more I tried to push them down, the worse they became.

My emotions were all over the place and the more I tried to keep them under wraps, the harder they fought to get out. The next thing I knew, I was crying.

"F-fuck." I muttered, leaning against the wall. The water continued to run down my back, the heat soothing the tense muscles there.

The sound of the door opening caught my attention, the sound of clothing hitting the floor following shortly after.

"Hey darling what's wrong?" Reaper asked, his hands slowly sliding around my waist.

"Nothing big.." I sniffled, letting him hold me. His warm chest pressed against my back, his hands roaming my front. He leaned his head against my neck, gently nipping the skin there.

"You don't sound okay. You want to talk?" He asked, his hands trailing down to my hips. He squeezed them, earning a soft whimper from me.

"I just have a lot on my mind, and my hormones are probably making things worse." I said and turned around, burying my face in his chest.

"You know you can tell me anything, right?" He said and kissed the top of my head. I nodded and leaned up to kiss him, feeling him lean down and kissing me back.

I pulled him closer, kissing him deeper as his hands ran over my sides, slowly making their way down. I whimpered, pulling away for a second.

"W-what about dinner?" I asked, and he chuckled.

"We can make dinner later." He said and pulled me close, his hands running down to grab my ass. I blushed, wrapping my arms around his neck and pulling him in for another kiss.

He pressed me to the wall, his hands grabbing mine and holding them against the wall as he leaned down to bite and suck my neck. I moaned softly, arching into his touch as his hands moved down to rub my inner thighs.

"A-ah Reaper.." I whimpered, tilting my head back. He chuckled, kissing down my chest and to my stomach.

"Let me make you feel better." He purred and kissed down further, kneeling down and looking up at me. He smirked and leaned forward, licking over my pussy.

"O-oh fuck.." I moaned, my hands resting on either side of his head. He hummed and leaned closer, licking my clit.

"Mmm such a good girl~" he moaned, slipping a finger inside. He curled it, rubbing my sweet spot. I bit my lip, feeling my knees shake.

"O-oh Reaper.." I whined, looking down at him. He looked back up at me, his eyes half lidded as he sucked my clit.

"I'll always take care of my sunshine." He said and stood, lifting me and carrying me out of the shower. He set me down, shutting the water off and picking me back up.

He carried me to the bed, setting me down and climbing on top.

"Do you want this?" He asked, and I nodded, blushing. He chuckled and leaned down, kissing me.

"I want to hear you say it." He said and rubbed my hips.

"Y-yes.. please, Reaper. I need you.." I said, looking up at him with pleading eyes. He smirked and lifted my legs, pushing them towards my chest.

"As you wish, princess." He said and thrust in. I let out a small scream, the sudden intrusion making my whole body shake.

"Shhh, it's alright.." he purred and started thrusting, his hands holding my hips.

"O-oh fuck!" I moaned, gripping the bed sheets as I tried to hold myself together. He groaned, leaning over and biting my neck.

"Fuck.. you're so tight.." he growled, his thrusts speeding up. I could feel him getting harder, and I let out a loud moan.

"S-so big.." I moaned and looked up at him, my eyes full of lust.

"Good girl.." he panted, reaching down and rubbing my clit. I squealed, bucking my hips up.

"A-ah, fuck.." I cried out, the stimulation almost too much.

"I know you can cum for me.." he moaned and kept thrusting, his fingers rubbing circles on my clit.

"O-oh, ah~ fuck, R-reaper!" I screamed, cumming.

"F-fuck.." he groaned and came, pulling out and cumming all over my stomach. He panted, and laid down beside me, pulling me close.

"How was that?" He asked and kissed my forehead. I snuggled closer, sighing softly.

"Amazing." I said and wrapped an arm around his waist.

"Good, now get some rest. I'll clean you up when you wake." He said and covered us up.

"Okay..I love you." I said, my eyes fluttering closed.

"I love you too, my little sunshine."
