So this snip came about when I imagined a scenario to bring about a Saber x kalied Shirou pairing. Fair warning it has a lemon near the end so no complaining as I did warn you.

Shirou POV-

It was considered a dream among males to have a harem. The idea that multiple girls of varying types all desiring the same guy sent indescribable feelings through their bodies. Shirou Emiya personally found that the reality of a harem leaves much to be desired. Now Shirou had nothing against the girls themselves or even the fact that they were interested in him. His problem was the fact that they fought over him all the time. It happens not just at school but whenever they meet with him at the center. Shirou sometimes wished he wasn't such a nice guy because maybe then he could say candidly how immature he found their behavior.

Shirou wasn't blind in seeing their affection but he did have some survival instincts. He knew that if he began to favor one over the other it would just cause more trouble in the long run. Best to let them deal with it until they were tired of fighting and then talk to them. Although that didn't mean he wasn't interested in girls it was just offsetting seeing them constantly fight over him. He was walking down the street when he suddenly lost balance and began to fall. Shirou sometimes wonder if he was cursed like in the saying, 'May you live in interesting times."

However this time was different and perhaps luck smiled upon him. He was caught and allowed to find my footing by a passerby. He looked at them and began to say thanks but no words left his mouth. Shirou was awestruck by the person right in front of him.

She was beautiful. Her hair shined under the light of the sun like gold, her eyes were captivating with that light green color, and her smile was something he could look at for hours and never want to leave. Yet what drew him was something that couldn't be seen. It was her presence as though he stood before someone great. Shirou wanted to be acknowledged by her. He couldn't explain it but if someone asked deep down he simply wanted to stand by her side.

She had a patient look on her face as though this sort of thing was common for her. Shirou was finally able to get his thoughts straight when he heard a rumbling noise that reminded him of a lion he heard on tv. He then saw how she blushed and her hands went over her stomach. Shirou put two and two together and did the only thing he could think of. He offered to treat her as thanks for her help. She refused at first but relented when her stomach growled a second time. Shirou then introduced himself and she in return gave her name, "Altria Penn". He didn't realize it then but that was the beginning of their relationship.

Altria POV-

It was a simple encounter yet it was the start of something wonderful. The boy, Shirou, was different compared to most men she knew. He was naturally kind and his face held none of the tells that indicated when a person wore a mask. What was a freely offered meal became an relaxing encounter. She would part ways with a full stomach and a bright mood. It seemed as though fate had made plans as the two would always bump into each other. What was mere coincidence became expected meetings. She couldn't really deny it in her heart the truth. She had grown to like the boy and his presence was a reminder. That so long as people like him lived then her actions truly did have meaning.

She wasn't really a normal person by any stretch of the definition. She had introduced herself by the name Altria Penn but it wasn't her true name. No her name was Altria Pendragon but she was known throughout the world as King Arthur. She is the once and future king who is destined to return to guide her people in their hour of need. She was able to return to earth every few decades in order to keep afloat of the situation with humanity. It was only possible due to the fact that she wasn't completely human and thus was capable of learning the skill "Independent Manifestation" from Merlin. She had never expected though to find someone like Shirou Emiya. She had legitimately begun to grow fond of the boy whose very existence seemed to make the day brighter for anyone nearby.

It wasn't long before she desired to stay and not return to her slumber. She had long since left the world and it was only due to her teacher that she could for brief periods manifest to keep watch over the worlds changes. It was scary how quickly she desired to keep him by her side but she knew that it was inevitable. She was after all a dragon in the shape of a human and dragons were known to be immensely possessive. It was surprisingly quick how she desired him but after suppressing her desires during her time as King it became easier after leaving the world to express her hidden thoughts.

So when our latest rendezvous was at its end I strengthened my resolve and spoke to this pure boy. I mentioned how I had to go back home in the next few days and that the likelihood of us seeing each other will be close to zero. So that is why I wanted our next meeting to be something special. I want to go on a date with you Shirou just this once not as a friend but as your lover. Just this once can we truly be boyfriend and girlfriend?

His face showed his surprise yet it was replaced with happiness. He happily agreed and we both promised to meet each other the tomorrow at the station. I walked away with a plan forming in my mind. I would grant him a great happiness in order to make up for never being able to meet with each other. I also considered giving him a gift unlike any other. A gift that never gave anyone else. I wanted this happiness to never end and yet I knew it would end one day. So let tomorrow be a day unlike any other for the both of us.

Illya POV-

I wasn't the only one to notice that big brother was spending more time in town than with everyone. Rin thought that Shirou found a job in order to keep himself busy, Issei had claimed that Shirou admitted that at times he couldn't stand all of the fighting over him and thus wanted some time away from it all, and Chloe even suggested that he had found a girl in town he fancied. I could accept the first two ideas but the third was impossible to consider.

So when Shirou came back home with a radiant look on his face I considered that Chloe was right. So when Chloe made a remark about him being surprisingly happy he simply stated that he had something planned for tomorrow with a friend. Mom was surprisingly unquestioning about any details but she had a look in her eyes that said how interested she was about it. Of course Ruby was all about following him the coming day and it was no surprise that everyone agreed. I don't think anyone expected what we saw that day.

We followed him to the train station where he seemed to wait for someone. It seemed ruby had a stalker function for those times when a magical girl had to follow someone for some reason. We saw how he seemed to perk up suddenly so we looked at his friend and were struck speechless.

She was beautiful to the point words wouldn't suffice in describing her. Her hair was gold, her eyes were emeralds, and her lithe figure resembled a fairy. Yet it was her very presence that made me unable to breathe. It felt like I stood before a class card only stronger and more pure. I think I could understand why big brother wanted to spend time with her.

Rin and Luvia wanted to march out there and confront Shirou immediately but we didn't want them to know we were following them. Sakura was growing paler by the second and I could swear that I saw her eyes turn red and her hair white for a brief moment. Me and Miyu didn't know what to do and Chloe wolf whistled at big brother's date.

We simply followed them as they continued their date and there was no denying that it was a date. He took her to several restaurants and game centers all day. He even went to several classical sating spots across Fuyuki. Yet it was at the end where he date suddenly guided him to a relatively new apartment building that had everyone up in arms. She grasped his hands and with a blush on her face guided him to a room in the middle floors. Of course Ruby had to speak out saying how the girl was really bold planning on going to third base, whatever that meant. Everyone seemed to recognize it though as they put on their war faces. The only reason there wasn't a bloodbath was Mother making a surprise appearance and making them not interfere. Of course when they complained she said that maybe should be incentive to not simply fight over a guy as he might seek out "greener pastures".

Still the smile on his face was blinding and yet why did it hurt to see it being shown to another girl? Perhaps this was jealousy that other people talked about. I didn't like this feeling at all.

Shirou POV-

When we arrived at Altria's apartment I thought that would be the end of our date. I was therefore surprised when she took my hand and guided me to her place. I was about to ask her what was happenning when she simply put a finger on my lips. She then spoke on how she would have to go home tomorrow and that she wanted to give me a gift before then. I saw how her face began to grow more flushed with every second and how she began to fidget. She then took a deep breath and undid her hair allowing it to fall down her neck. Once more she took my hand and guided me to what appeared to be her bedroom. I wasn't dense like most thought so I connected the dots and immeadiately blushed. She said that if I was uncomfortable then she would stop but she truly wanted this. A memory that would never fade so that despite being unable to see each other again we would have a place in each others hearts. My mouth felt dry but I slowly began to undress. I could see the joy in her face and her smile was blinding to my eyes. There was no going back now.

Lemon start-

She was truly beautiful beyond words. She didn't have the curves that most women had. Yet it didn't matter when her very existance seemed to shine like the sun. She gently took my hands and guided me to her bed. She lead my hand to her breasts and made a circular motion. I knew basically nothing about sex but she taught me how to please her. I kissed her gently yet it only served my inflame my passions as our lips stayed connected longer with each kiss until our tongues began to battle. She was without doubt my better as her tongue entered my mouth and yet she allowed me to enter hers. My free hand found its way to her vagina and felt just how wet it was.

This continued for several minutes yet it felt so much longer. She then stopped our kiss and her head went lower till she was staring at my erection. Her breath tickled my member and she started with a simple kiss on its head. That was followed by her taking it into her mouth as her tongue lapped at my dick. She missed not a single spot as his member was attended to in her mouth. It was too much and he couldn't even cry out as he came for the first time. She was surprised but recovered quickly as his seed splattered all over her face. She gazed at his essence on her hands and slowly licked them clean and with ferver cleaned his dick with her mouth.

He chose to repay her by doing to her the same thing. As his head lowered to her folds he could see the fluids leaking out. He couldn't help but wonder how it tasted and thus licked her pussy. Her cries sent lightning down his spine and he went back with even more effort to please her. His tongue soon found its way into her folds as he tasted her insides and as her sweet juices entered his mouth he was starting to get addicted to her taste. Soon her body shuddered and he could tell that she came just like he did. He brought his head to her own and kissed her gently. No words needed to be said as she spread her legs and he placed his dick at her entrance.

It was an indescribable feeling entering her like he did. She was incredibly tight and it felt as though she would crush his member but the softness of her inner walls made it easier to handle. He shuddered at the sensations he felt and simply allowed himself to bask in the feeling of filling his love. He then saw as his partner began to move and he reciprocated by slowly pulling out. It was akward as he was completely new but she had a surprising amount of experience to aid his progress. He then began to get used to it and set up an even tempo with their thrusts met each other and pulled away at the same time. He lowered his head and kissed her as he embraced her in this intimate manner.

He didn't want to let her go. He wanted her to stay by his side until the end. But he knew that if she could she would have stayed with him. So he simply decided to enjoy this moment. So when his release was made clear he didn't hold back. He used the last of his energy to make her cum alongside him and their release was complete. He felt so tired as his eyes began to close but her last sight was of her radiant smile as she held him in her arms. This was what happiness felt like.

Lemon End-

Altria Pov-

It was time to return home despite my desires. I had finished everything and was about to disperse my body. Shirou was still sleeping in the bed they made love in and despite wanting to say goodbye one last time she couldn't. He knew nothing of the moonlight world and she didn't want him to get involved in this blood soaked world. So she left a letter and a picture telling how she had to go back home. Telling him that their time together was wonderful and how she would remember it till the end of her days. Telling him that it was alright if he decided to one day move on and find another lover. After all she wanted him to be happy just as he made her happy.

Her body seemed to break apart as small golden lights appeared around her. And thus did Altria Pendragon return to the Isle of Kings. Thus did she return to her dreams yet now they would be filled with memories of her love. As for Shirou he would return to his normal life as his friends and family would question him about the girl he spent time with. Truly it would be quite chaotic but it was truly his life. Thus ended a story of a chance encounter.
