Your POV:

I lived with Sans and Papyrus after monsters had been freed from the underground. They were kind enough to take me in when I hit rock bottom. I was literally at the worst point I could be at. After they took me in I had grown rather attached to Sans. And I had the biggest crush on him. But I never figured that he would like some low life human like me.

I was on my way home from Grillbys new surface restaurant and brought Sans a bottle of ketchup. I walked through the front door and called for Sans, "I have ketchup!" There was no answer. Which was strange because Sans loved it when I brought ketchup home from Grillbys. No matter how lazy he was he would always come to greet me after I get home. But then I started hearing strange noises coming from his bedroom. So I walked towards his bedroom door. The closer I got the more I could hear. That's when I heard him say my name.

I figured something was wrong so I went up to his bedroom door and knocked on it before saying, "Sansy, is everything alright? Do you need anything? I thought I heard you call for me." That's when I was magically in his room sitting right in front of him blushing like a crazy mess that I am.

I looked down slightly and saw his massive and already extremely hard member that was summoned. My face was ten different shades of red after looking at it. But I couldn't stop staring at it. It was just so big (XD sorry not sorry. I'm trying to act mature about this). He then crawled towards me and whispered in my ear with a seductive tone and his hot breath against my ear, "(Y-Y/N), won't you help this bag of bones out..~? I need you~ and you did ask if I needed anything~"

I blushed even more somehow before speaking, "Yeah I did say anything. What d-do you need help with Sansy?" He bit his bottom lip(?) and moved down to my neck before kissing on it. Eventually he found my sweet spot which caused me to moan out, "Ah~ Sans~" I felt him smirk as he began to tease my neck with love bites as he groped my breasts through my shirt causing me to moan even more for him. Before I knew it my pants and underwear were off along with my shirt and bra.

I was already soaking wet without even realizing it. He smirked even more and he rubbed the tip of his massive member against my soaking womanhood causing me to whimper needingly. I started begging for him to enter me, "S-Sansy please~ I need you now~." That's when he entered me full force with one thrust causing some pain. He saw the pain on my face and waited for me to adjust.

After a few minutes I bucked my hips instantly feeling pleasure. He took this as a hint and began to thrust deep into me at a slow pace. After a few moment his pace began to speed up some which sent even more pleasure through both of our bodies. "Ahhh~! (Y/N)~! I'm g-gonna cum~!" I felt a knot in my stomach and knew I was close as well.

I wrapped my legs around his hips, causing him to go deeper inside me, as I gently grabbed onto his ribs, "Mmm~! M-Me too~! Ahh~!" Soon we both climaxed and after ridding out our climaxes he pulled out of me while we were both panting heavily like dogs.

He then rolled over and lay next to me on his bed, pulling me close to him. I could feel his chest very slowly rise and fall with each small breath he took. It was, honestly, really relaxing. I snuggled close to him and lay my head on his chest before saying, "I love you, Sans." He smiled and said, "I love you too (Y/N)." It was so relaxing to have his arms around my waist because I soon fell asleep with a smile on my face.
