Yes this was a thing at one time, I was a calculator lover

Before sans and I where a thing, around the first days when we where just aquantinces who saw each other on occasion I was well, playing around with Mettaton. The flirtatious comment here and there and basically this is how we started.

Mettaton had taken me out on a amazing date basically, the food was top notch!!! We where sitting together alone and Mettaton was talking about all the lime light and his amazing fans, when he turned to me and said "darling... Can I confess that I'm so in love with the beauty right in of me... And I will forever and always want to be with you" He gushed softly "mettaton... You don't mean it..." I blushed deeply.

"I do, will you please... Please be my girlfriend" He asked softly. "Mettaton... I..." I was awestruck but I was so nervous about dating but was this true love? Could he be the man iv been looking for? "I-""Would you two like desert?" The flame man asked, at that time I didn't know his name was Grillby... "Ya know what? Put it on my tab Grillby. One piece of the cheesecake for my young lady and ill have my regular" Mettaton responded.

"What's your regular?" I asked "like a martini but it's full of ball joint lube and stuff so nothing creaks or scratches" Mettaton chuckled.

And then there was Sans, he was sitting at the bar talking to Grillby, but I caught him on occasion glancing over at me. I felt a little weird but didn't say much about it. "Do you need some time to think about my offer?" Mettaton asked. "Yes please" I nodded.

So later on that night

I was walking home with mettaton when I heard a voice, "hey" it said. I spun around to see Sans, "what do you want shorty?" Mettaton asked. "Butterfly... Can we talk?" He asked.

I nodded and left Mettatons side, "i... I like you... And I don't want to loose you to some robot in heels" Sams suddenly confessed. I was shocked! Stuck in a love triangle "sans I..." I couldn't speak. "One date, please let me prove I'm better than him" He bursted out.

Mettaton sighed "it was only way to get you to confess" Mettaton suddenly spoke. "What?" I was schocked. "I knew Sans was inlove but being a utter tsundere the only way to get him to confess as if he knew he was gonna loose you" Mettaton smiled then "as much as I love you, you and sans are a cute pair" Mettatok chuckled and walked off satisfied.
