Date With A Blueberry

You feel your cheeks burn up even more as Sans backs up a little noticing you look at him with a shocked face as he scatches the back of his skull awkwardly. "U-Uh s-sorry..B-But I have a very important q-question to ask.." He states stuttering a bit with a dark shade of blue appearing on his cheekbones. "Yes Blueberry?" You ask him curiously with a warm smile after calming down a bit and regaining your composure as he takes a deep dreath before continuing with his question. "W-WILL YOU PLEASE GO ON A D-DATE WITH ME?!" He finishes as his face turns an even darker blue than before as he looks you in the eye seriously. You let out a slight giggle as your smile widens a little. "Blueberry..I would love to go out with you.." You reply calmly to him before kissing his teeth. "Now tell me..what's with the Teddy Bear costume?" You ask him with a cute curious look on your face. "Oh this? Um..right this..Paps told me that I should wear it to apparently 'impress' you.." Sans replies to your question in a slight mumble. "He said that there would be no way that you would turn my proposal of a date down..and I guess he was right." He finishes as he frowns a little making you frown as well before hugging him close. "Blueberry..I would accept your proposal for a date either way..you didn't have to dress up like a bear silly." He stays quiet for a few moments while listening to your kind and reassuring words before hugging you back. "Thanks Y/N..I really appreciate It.." He says sincerely as he kisses your forhead. "Um..WELL I BETTER GO GET READY FOR MY DATE THEN!!" He says excitedly and happily before running to his room. You let out a small sigh before walking out of the house and to your house that was just accross the street from Sans' and Papyrus'.

A small smile forms on your lips as you walk inside your warm and cozy house and make your way upstairs to your room. You open your closet doors up and look around for anything that would cute on you for a date. After hours of trying on several different outfits you settle with a dark blue spaghetti string T-Shirt and a light blue frilly skirt because you wanted to match with Blueberry. You then walk into your bathroom and take a quick shower after making your final decision on what you wanted to wear. After taking your shower, you blow dryed your hair after changing and walked out the door of your house after grabbing a dark blue side purse that went perfectly with your outfit.

You arrive at the Skeleton bros. House and ring the door bell and after waiting for a few moments Papyrus answers it and gives you a slight smug grin before holding the door open for you gesturing you to walk in and without him even offering it, you walk in. "hey you and my bro about to have your little date eh?" Papyrus asks you while grinning. "Yep! Hey where is little Sans right now?" (You call Blueberry by his real name when near Papyrus) "heh..my bro isn't even close to being ready yet I bet.." Papyrus replied with his smug grin still on his face but just then after he finished his reply Sans came walking in out of his room and walked towards you with a big smile on his face. It was obvious that he was excited to go on his first date as so you were too. "Ready Y/N?" Sans asks you with stars in his eyes as he gently grabs your hand making you smile back with a giggle. "Yep when ever you are!" "Where are we going anyways Blueberry?" You ask him after already walking with a few meters away from his house. "Hm..I think Muffet's sounds good, you?" He asks you with a warm smile. "Of course! I'm fine with anything you want!" You exclaim cheerfully as he blushes and smiles at you.

You smile as you and Sans arrive at Muffet's as Sans pulls a chair out for you to sit in and sits next to you. You both order what you want and soon recieve the food that you ordered from Muffet and eat together happily occasionally making a joke about something. You and Sans eventually finish your meal and left Muffet's after Sans pays the bill for the food. "So uh..Y/N.." Sans starts while blushing a little and looking at you while you walked with your hand in his. "I was wondering if you w-wanted to be my girlfriend.." He finishes as you look at him with sparkles in your eyes. "Of course Blueberry!" You exclaim happily as you hug him tightly and nuzzle him lovingly while he lets out a cute giggle and hugs you back. "Yay!!" He cheers happily while trying to nuzzle you back.
