Gold's Eye GasterSans X Reader

Happy Valentines Day

The next morning you awoke with a start feeling the cold air brush your skin, you sit up lazily to find a letter sitting next to you with a box of chocolates and a bouquet of (fav colour) Roses , the writing was surprisingly neat and those where like extremely expensive chocolates and the most beautiful roses!. You read over the letter with a small smile

Dear Y/N

You smiled a little opening the chocolate box selecting your favorite and eating it. It was absolutely delicious, You sister peered into your room "wow... looks like you had some really quiet but amazing sex last night... how did you get all these gifts?" She asked, "Oh it came from my imaginary boyfriend" You laughed a little dropping another chocolate into your mouth. "can I have one?" She asked. "nope" you closed the door and got up. You stretched and smiled to yourself and walked over to your dresser and got out a slightly fancy outfit and began to fix yourself up. Wanting to give him a surprise when he visited tonight. 

It was later and the moon came out, you walked outside to see him in a formal jacket and tie, He smiled "hey beautiful" He admired how wonderful you looked. "hey Handsome" You giggled as he took you into his arms they gently rested on your waist. "you promised a story tonight" you reminded him tapping his jaw. "right..." he nodded letting go of you for a second as you plugged in your itouch and the music softly played in the background, Your rested your head on his chest as you two danced. 

"It was a few years ago, Me and the boys where working with our dad Gaster. We where all busy at work when Gaster accidentally spilled his coffee on the time machine. Sparks where everywhere, Sans ran at him and so I ran grabbed him.... Oh back then I was just Sans... I grabbed the children and I shielded them from the blast... I was shocked with black electricity as Gaster was disintegrated in seconds but the sound barrier was too slow  and suddenly a loud bang and Gaster's soul flew back and crashed into my spine and I was struck with electricity causing the soul to turn to dust which rested on me.. So I became a piece of my father and myself. I can still speak with my father, He's in limbo between the real world and death, He said if I couldn't find someone who wanted me outside the void... it would consume me... The moment I saw you... I fell in love..." He confessed quietly. 

I fell in love with you
