[(Y/N)'s PoV]

Mettaton was clapping for me. "Oh darling, you and Sans are the most perfect couple! I cannot wait to see you two dance tonight! What did Alphys call this? Uh... shipping maybe..." Mettaton started muttering to himself as we sat outside waiting for Sans and Papyrus. Toriel was watching Frisk for the night, and the dance was at the MTT Resort, so it was a long way from the Ruins.

"okay, we're here." I heard Sans and Papyrus walking towards us. Sans was wearing a tux but with a light blue tie, and Papyrus was wearing the same but an orange bow tie. "Oh my! You look WONDERFUL darling!" Mettaton screamed and jumped onto Papyrus, hugging him. "O-OH, THANKS METTATON." Papyrus waved and Sans waved back, then they walked inside.

Sans leaned on the wall next to me. "it's a beautiful night tonight."

"Yeah." I agreed. Even though they had no sky, they had a roof with different crystals, all functioning like stars. One might not be there next time, and there's always a new, different one appearing. "well, should we go inside?" I nodded and he took my hand, standing straight and leading me in.

And boy, it was crowded.

It was full of monsters, dancing and having a good time. It made me happy for some reason. I just feel a spark of peace here. The walls were painted with pink hearts (much like Mettaton's), and a big banner saying 'Happy Valentine's Day.' I looked to the stage and saw Napstablook at the DJ stand and Shyren with a microphone, singing. "y-you wanna dance? not that i'm forcing you or anything, i mean if you're uncomfortable because i sure am because it's just so crowded and i could mess up and-"

"Sh." I pushed him on the dancefloor and I put my right hand on his shoulder, and my left hand holding his. He slowly put his hand on my waist and we started dancing to the beat of the song. "i.. love you. you know that?"

"Pfft, you always tell me that. It's nice that I know you care though. I think it's sweet." I looked over to the right and saw Alphys and Mettaton. Alphys nodded and went to a different room. "Alright darlings~ We're going to take a break with the songs for a bit so that you can get food, drinks, or probably leave if you want to, but that's up to you guys." The song stopped and they just played a nice beat in the background. Chatter started to stir up so Sans took me to one of the rooms. "That's a big bed actually..."

"i heard they were big, but not this  big." I started to chuckle. "w-what? what's so funny?"

"I-I was gonna say..." I calmed myself. "That's what she said."

"you...." He covered his face. "need to stop this madness." I started laughing. "Sorry, sorry. It's your fault, you brought it upon yourself." It got silent. "well, at least we have privacy now."

"Yeah." We both sat on the bed, looking different ways. "i've uh, been wanting to ask you this for a long time, but... uh." He twiddled his thumbs. "maybe it's about time we actually have sex?"

"What?"

"i mean, if you don't want to that's fine. i'm okay with anything you have concerns about. i just want to make sure that you're okay with it and that-" I kissed him. "You're a bit sensitive about what I think." He blushed dark blue. "oh, well, i guess that's a good character trait, am i right?" We started with a light kiss, then he got more aggressive. He inserted his tongue into my mouth, and explored it, licking everything to my own tongue to the roof of my mouth.

He was stroking my sides now, taking small breaks between the kisses to say how beautiful and unique I was, how he loved me so much and never wanted anything bad to happen to me. He started to tug at my dress, begging to see me without it on. I started to take it off.

How wrong that was.
