Chapter Text
When he first met you, you were so shy towards him. You only just gave him a small wave and a shy smile, he didn’t know why you were so shy but thankfully his brother, Papyrus, helped melt some of that shyness away. You were a quiet person and tended to keep to yourself, but you still liked to be the shoulder your friends could lean on and be there to listen to your friend’s problems. You were the strong silent type, you didn’t like to burden your friends with your problems when they had their own to deal with. Sans was able to get that from your first meeting by taking a quick peek at your soul, he had to make sure you’d be safe for monsters to be around as not every monster was as strong as he was when it came to humans. He was glad to know that it was safe to be around you, even if you didn’t talk much. Thankfully Papyrus did most of the talking when it came to you, apparently the two of you were friends via cooking classes. Pap really enjoyed talking about you, saying about how nice and patient you were and how you made really good food and how you seemed to be smaller than most humans your age. The last one made you blush in embarrassment and hide your face in your hands as the taller skeleton asked you what was wrong. Sans couldn’t stop smiling whenever he thought about that hilarious, adorable day.
-------------------
You would be over at his and his brother’s house often as Papyrus wanted to hang out with his cooking buddy more and wanted Sans to get to know you better. The taller skeleton wanted you and his brother to be friends and get along. It was pretty easy to warm up to you, you listened to his puns and ramblings and enjoyed helping him out with some pranks. He eventually found himself taking a special liking to you, you talked to him more often and would sometimes even make a pun with him. You even seemed to love talking about Papyrus as much as Sans did, you loved cooking with both him and Undyne as well as making sure the house wouldn’t burn down, and no matter how frustrated or angry you were on a bad day, you never snapped at anyone.
He found that he liked it whenever you would sleep over and he would get to see you curled up on their couch as he forbid you to sleep in his brother’s room without both skeletons there with you. Sans didn’t like his brother’s scent on you so much as he loved to be super cuddly, to try and fix that he would lend you one of his jackets to sleep in. You at first told him he didn’t have to, but his insistence made you take it. It worked out for you because you loved to be in super baggy clothes and his jackets were really comfy and warm even if it was like an oversized dress on you. Sometimes you could even only wear the jacket and your underwear since it was so huge on you. It drove Sans crazy to see your sleep shirt and pajama bottoms on the table and you only sleeping in his jacket, he just wanted to go over there and hold you close and keep you in his arms forever. When he told you about his romantic feelings towards you, you let him down gently. You explained that you had recently broke up with your significant other and you didn’t feel ready to get into a relationship so quickly, he understood and told you that he could wait until you felt ready. You thanked him for understanding and asked if you could still be friends, he accepted.
------------------------
That happened three months ago and you were currently hanging out on Sans’ lap on the couch, Papyrus sitting next to the two of you as you three watched an MTT movie. A couple of times your phone would buzz, but you didn’t answer it as you felt that would be rude. However, it quickly grew to be an annoyance so you turned off your phone. “Who’s botherin’ ya?” Sans didn’t like it that someone was texting you so frequently. “Probably just my date for tomorrow.” Sans’ claws dug into the couch cusions and his smile tightened in anger. “I’m sorry, what did you say?” He surprisingly kept his voice steady. “Oh, I said that the person who was texting me was probably my date for tomorrow.” He gritted his teeth at that. “Why didn’t you say anythin’ to us ‘bout it?” He growled, you just shrugged as you kept your eyes on the television screen. “I didn’t think it was important, we’re just trying it out and seeing how it goes is all. It’s only my first date with him tomorrow, it’s nothing serious.”
The skeleton still didn’t like it, why didn’t you tell him?! Did you forget he liked you? Did you think he didn’t like you like that anymore? Did you think he was already with someone? Either way Sans was very unhappy to see that someone else had taken an interest in you, he was going to make sure that one date stayed as only one date. The skeleton didn’t want to possibly scare you off with him being too possessive or protective of you. Nor did he want you to get the wrong idea and just stay away from guys in general. He would easily get you to fall for him, after all you spent most of your time at his home and loved being there for him. He would make sure that you would be his new mate, he would take care of you. He would shower you with all the love and affection you deserved, he would keep you safe, he would be there for you to lean on if you ever needed to vent to someone, he would do his best not to harm you like some of his previous mates, and he would be the one to reap your soul and eat your body when it was time for your lifespan to end. No one else would be better for you than him, no one would treat you the way you deserved to be treated. Only he could give you the love and attention you deserved, the only person who knew you as well as he did was Papyrus and he knew that his brother didn’t have romantic feelings for you.
Someone was eventually going to take advantage of your patient nature and really hurt you and he wasn’t going to just sit there and let that happen! Sometimes you could be too willing to listen to someone’s problems and being someone’s rock could really put a lot of pressure on you as you did it with so many people. There would be days when you were sad from hearing what made the other people in your life so distressed, but you always kept that sadness bottled up inside so you didn’t have to worry anyone. He knew that you would sometimes stay up late at night to cry silently because you couldn’t keep it all bottled up anymore, the skeleton would want to go to you but he knew that would make you feel even worse and he didn’t want that. It hurt him that you wouldn’t confide in him or anyone else, you deserved to let out your feelings to someone. Even the strongest people have their moments of weakness and Sans wanted to be there for you when you were weak, he wanted to be your rock, he wanted to be the one who could help keep you grounded, he wanted you to confide your problems with him, he wanted you to trust him enough to tell him if something is bothering you, he didn’t want you to feel hurt and just cry to yourself in the middle of the night, he wanted to stop your emotional pain, and he wanted you to stop setting such an unrealistically high emotional expectation for yourself and help you understand that it was okay to tell someone about your negative feelings.
Thinking about how secluded you were about your problems made him frown. You shouldn’t have to feel like you have to keep everything bottled up inside, it wasn’t right. Couldn’t you confide in him? He’d ask you about it tonight when Papyrus went to bed, for now he would just keep you close and focus on the stupid movie. He wrapped his arms around you and pulled you back so that your back rested against his chest. You were a bit surprised at first, but relaxed against him and put your hand on top of his. That action made his smile less tense and helped him to calm down a little bit. His boney tail curled around you to keep you close to him, you let out a small hum at the cuddly action. It didn’t bother you as Sans was just as cuddly as his brother was, even if he would never admit it. The smaller skeleton let out a soft purr, oh he wished he could kiss you right now but it could wait until he made you love him. He would do his best to lead you down the right path, he’d play you like a puppet but he’d make sure that his precious puppet was tended to oh so caringly. He’d make sure the strings that tied you to him were strong and supported and that they wouldn’t dare break away from his grasp. Sans wanted you to be oblivious as possible to how he would manipulate you, after all he’d hate to have to hurt you to get you to understand and accept his love for you. The last method however, wasn’t completely off the table it was just going to be his last resort.
“Hey ____. What’s yer date like or is this the first time yer meeting ‘em?” You looked away in thought for a moment. “I met him in person first and he seemed like a decent guy. We talked for a few weeks to get to know each other a bit more then he asked me out on a date and I accepted. Besides, I know that anything goes wrong or if I feel uncomfortable that I can call you or Papyrus to pick me up, right?” Papyrus happily nodded, but Sans felt a bit torn. He was glad that you trusted him to help you out in a tough situation, but he still didn’t want you anywhere near a male that he didn’t approve of. He nodded anyways, he needed you to know that he would always be there for you. You smiled and hugged Sans’ hand a bit tighter in appreciation which made his soft purr rumble louder. You loved it when Sans would purr like a bit cat, not to mention the vibrations his ribcage gave off felt really nice on your back. “Well aren’t you just having the most purrfect day, Sans.” Sans’ grin got wider and his purring got even louder as he held you closer then nuzzled the top of your head. Papyrus groaned through his smile as he kept trying to focus on Mettaton’s movie.
Sans was trying his hardest to not kiss your cute face, he really liked that you felt comfortable around him to joke with him. It had taken him the longest time for him to get you to let your guard down around him, he didn’t know why you didn’t people easily and at the time it had frustrated him a bit. Now however, he was glad for it now as it meant that others couldn’t get close to you until a lot of time passed by. It gave him time to get closer to you, not to mention you were the type who could hold a grudge for a good long while depending on the situation so he was able to drive some people away pretty easily. It usually aspired to making those who tried to get too close look like monster racists, it wasn’t that hard. Not to mention he’d get to be cuddled and doted on for the rest of that day which was wonderful.
As the show went on, eventually Papyrus went to bed and you fell asleep against Sans much to his delight. Sans carefully moved the two of you so that he was laying on the couch with yourself curled up on top of him, you were zipped up against him in his jacket with your head resting on his chest. He kissed the top of your head as he settled down to get comfortable, his arms wrapping around you to keep you from moving around too much. The monster closed his sockets as he quickly fell asleep, contented that you wouldn’t be going anywhere anytime soon.
‘Don’t worry ______, I already know ya love me even if ya don’t know it yet. I’ll make sure ya fall me just as hard as I’ve fallen for ya, I’ll make ya take the right path to get straight to me. I’ll make sure no one will ever hurt ya again and if someone ever dares to try, well…heh…I’ve got a couple of ideas of how to take care of any threat. I just hope I don’t have to break down yer soul in order to get what I want, but I’ll try and save that method for last…please don’t ever try to run or hide from me though kitten. I’ll always find ya, no matter where ya go or whatcha do. I’ll make sure that you’ll always return to me and only me…I promise.’
