Pulling My Heartstrings (Undertale Au Smut)

Reaper!Sans x Angel!Reader

I looked down quietly, walking through the void with my stark-white wings folded upon my back... I was meeting up with Sans, otherwise known as Reaper... I found myself coming to a stop, my wings spreading out as I stretched tiredly. I squeaked as I felt a bony pair of arms wrap around me from behind, hearing a deep chuckle from him as well.

"So, what are you up to today?" He asked, turning me to look at him as he grinned down at me. I smiled, hugging him around the neck.

"Well, I wanted to get out of the house, so I was thinking about going for a fly." I replied, blushing lightly as he chuckled, pulling me up into his arms and kissing my cheek. I smiled shyly, hugging his neck.

"Well, that sounds nice." He hummed, walking a little as he held me to him, my wings stretching out a bit. I looked down as he stopped, finding we were near a tree. I was set on the ground and smiled, leaning up and kissing his teeth, his smile widening as his arms wrapped around my waist. He kissed back, his tongue sliding out as he licked my lips, causing me to giggle softly as I opened my mouth, feeling his tongue slide into my mouth. I wrapped my arms around his neck, smiling happily as I leaned against him. He chuckled, holding me close as he pulled back.

"Good girl." He teased, nuzzling my nose with a grin. I blushed, giggling softly. He chuckled, leaning down and kissing me again. "Go ahead and stretch your wings, beautiful." He purred, making me blush lightly. I nodded, stepping back as he smiled. My wings spread out as I flapped them, starting to float into the air as I smiled at him. He smirked, standing underneath me as he watched.

"You're not going to join me?" I asked, tilting my head curiously. He smirked, shaking his head.

"Nah, I'm just gonna watch." He hummed, leaning against the tree and smiling up at me. I shrugged, smiling before I began to rise in the air, the wind blowing through my hair as I flapped my wings. I was so happy, I couldn't help but laugh softly.

"It's so pretty up here!" I called down to him, hearing him chuckle. I flapped my wings again, starting to go higher as I smiled, spreading my arms out beside me. I looked down, my smile widening as I saw Reaper watching me with a grin. I flapped my wings to start spinning in the air, the wind hitting my face as I giggled, my wings starting to slow me down. I was smiling widely as I stopped, looking down and finding myself higher than I meant to be.

"Are you alright?" Reaper called, making me look down. He was staring up at me in concern, making me smile.

"I'm fine! Don't worry, Reaper!" I called back, flapping my wings a few times to start falling slowly, looking down at him. He sighed, shaking his head.

"I swear, you'll scare me half to death one of these days." He murmured, watching as I flapped my wings more, slowing my fall as I smiled down at him.

"Awe, I'm sorry." I hummed, pouting as I landed. I wrapped my arms around him, looking up at him with a sad smile. "Do you forgive me?" I asked. He smirked, chuckling as he leaned down and kissed me gently, making me smile softly.

"Of course." He replied, hugging me to his chest. I blushed, nuzzling into his coat and closing my eyes. He chuckled, stroking my hair.

"You want to come home with me? We can have some fun together." He purred, his words causing me to shiver. I nodded, feeling him pick me up and hold me close.

"Okay, let's go then." I agreed, hugging him around the neck. I closed my eyes, my face burying into his coat. I smiled, feeling his arms wrap tightly around me.

"Hold on tight." He warned, his voice making me blush. I felt a small tugging sensation, making me smile softly. I held him close, feeling the tugging grow stronger, causing me to giggle. After a moment, it was gone, and I opened my eyes, smiling at the familiar setting.
