Prompt: Serenity was given a mission by her Master. Assassinate the Master of Saber. His defenses were pitiable, it should have been an easy job... but she couldn't kill him? He was immune to her poison...? Who was her master again? Who cared when she could cuddle up with Shirou Emiya and have him not die no matter how much her naked body pressed against his!

The Master of Saber was not the only Master staying in this building despite its putrid defenses. She had noticed when she crossed the weak bounded field surrounding the building that there was a second servant here. Given its position as a sentry on the roof, and the lack of combat ability displayed, it was likely that they were one of the unknowns Archer or Caster. The former being more likely as she could not imagine a Caster living behind such poor defenses. Serenity was certain that she had been caught, but either the Archer was incompetent enough to miss the window opening on its own or did not care that she was here to kill Saber's master.
If Serenity had intended to kill Archer's master, then he might have acted, but it seemed he didn't want his ally to be protected the same way. Serenity had no interest in Archer's Master tonight. Her Master had ordered the death of Saber's Master and not mentioned anyone else. Whether it was because her master didn't know about Archer's Master or not was irrelevant. She would follow her orders absolutely.
Serenity was a bit surprised when she found the Saber class servant- asleep on a sleeping mat. And in a different room than her Master. She snoozed lightly, her room one door down from her Master. Serenity was careful to be silent as she slipped past the open doorway, still in her spirit form and under presence concealment. Serenity did not care why Saber was not sleeping in the same room as her Master. All that she cared about was how it made killing her Master easier. She slipped open the door of the smallest bedroom and here she was.
With the slightest of sighs, Serenity allowed herself to materialize within his room as the door latched shut behind her. She looked at the red-headed boy sleeping in front of her. He was young, still just a teenager and yet she would kill him without hesitation. His brow was furrowed as he slept, his body damp with sweat. He turned restlessly in his bed. She did not know who he was or care. All she knew was that he was the Master of Saber in this Holy Grail War, and so her master had ordered his death. She did not know or care who he really was, she just knew that he would die.
Serenity removed her glove and pressed one finger to the boy's wrist. And that was it. With her job finished, Serenity did a 180 turn and vacated the premises before his servant woke up and realized their master was dead. Or at least she tried to, but the Master of Saber had cast their blanket away during the night and Serenity had missed that it was on the floor right in front of her.
And so the graceful unfailing Hassan of the Serenity stumbled. It was a slight thing, but it led to her bare foot brushing up against the redhead's. And some drool trickled out of her lips and onto his arm. Serenity blushed lightly at her mistake, but thought nothing of it and exited the room leaving only a corpse behind. Her Master would be pleased.
"You told me that Saber's master is dead," Atrum Galliasta was not pleased with his servant.
"He is," Serenity nodded in confirmation.
"Then tell me why my familiar spotted Saber engaging in combat with Rider today? Or why Shirou Emiya was by her side?" He demanded coldly. "That does not look dead to me."
"But I touched him?" Serenity tilted her head to the side. She was certain of that. She had not just touched him once but twice even. "He is dead," she repeated, adamant that it had to be true.
"He is not!" Atrum snapped. "Do you think your Master is some fool? I am not one of those Eastern Mages you are used to dealing with. I am the Head of the esteemed Galliasta family. I know what I saw, and that is the treacherous son of the Magus Killer alive. The Knight of Betrayal by his side! And I saw them engage Rider!"
Serenity bowed her head in obedience. "My apologies master, I was simply astonished that he somehow managed to survive. I won't fail again." How was he alive? It truly did not make sense. Serenity had never failed to kill a target before. Her poison was supposed to be absolute- strong enough to kill an adult elephant with a brief touch. There was no antivenom to her poison. It was an absolute authority. There had never been an exception before. Could he somehow be the person she had only dreamed of? Of course not, that thought was only bound to lead to disappointment.
Atrum scoffed. "As if. You won't get the chance to fail again. Saber will have their defenses raised and you have proven yourself incapable of killing him under even the most optimal of conditions. You are the most useless servant in this war. I will deal with the Rebel Knight myself in due time. Her master may be the son of the Magus Killer, but he is still an Eastern Mage. You can go back to surveillance as I prepare to actually win this war." He turned back to his child compressor, silently dismissing the loyal assassin.
"As you wish Master," Serenity nodded and departed from his workshop.
Serenity was back here again and more confused than ever. Her Master had only told her to watch and that had honestly been her intention. She had just gone to see how they had upgraded their defenses. To see if her Master was right and the boy- Shirou Emiya was really still alive. She had expected him to be wrong. That she had murdered the wrong person somehow. She had been certain that was the case…
Instead, it was as if she had never been here. Saber had not raised the defenses of their fortress, nor were the wards in disarray from the death of the holder. The girl living here still had her servant stationed on the roof and there were still three people slumbering inside. It was impossible, but somehow it was reality.
How? Was Shirou Emiya truly immune to her poison? Was he truly the man of her dreams? There was only one possible explanation. The servant she assumed was Archer. Perhaps he was a Caster, just not one focused on combat or defenses but healing. Maybe it was the legendary Acelepius. There was supposed to be nothing that he could not heal- even death. He was not a combatant which is why he continuously allowed her to enter. He knew how she killed and knew that he was capable of countering it but would lose if he engaged directly. So he must have simply waited for her to leave and then healed the boy without saying a word- having the ability to counter even her toxins somehow.
Serenity refused to acknowledge the contradictions in that logic. How could Asclepius know that her method of assassination would be poison and nothing else? She had yet to fight a single opponent in this Grail War and had spent nearly every second of it in her spirit form under presence concealment. There was not a world where the Caster or Archer, or any other servant aside from the First Hassan could have possibly recognized who she was and realized it would be safe to let her carry out her assassination on his ally.
Serenity stepped back into the room holding the master of the house. The scene was the exact same as she had left it the previous night. The red-headed boy sleeping on his mat, the blanket tossed to the side as he tossed and turned. HIs brow was furrowed and she could see the sweat glistening on his skin. He was once again shirtless and only wearing a pair of shorts. The floor had no new marks or stains- still as spotless as ever. The room was still completely bare and cramped. All that there was aside from a mat for him to sleep was a small desk and a single wooden chair.
Serenity sat down on the floor next to Shirou Emiya and smiled slightly. It was a nice dream but it would end now. She extended two fingers and placed them gently against his wrist, feeling his pulse as it stopped for the final time. Any second now his heartbeat would slow to nothing as the toxins surged through his blood and to his heart.
… Why hadn't his pulse stopped? That wasn't possible! He couldn't actually be unaffected! Maybe his arm was a prosthetic? You touched his foot too. She reached across the mat and grabbed Shirou's other hand in hers, squeezing it tightly. He stirred slightly in response to her grip. Her heart was pounding in her chest as she squeezed both of Shirou's hands desperately. She was just waiting for the punchline. The toxin was just taking a minute to reach his heart. He HAD TO DIE. NO ONE COULD SURVIVE. ANY MINUTE NOW HE WOULD BE DEAD AND SHE WOULD BE ALONE AGAIN.
A tear dropped onto her lip. Serenity wasn't sure when she had started crying. Another tear rolled down her cheek and dropped down onto the stomach of the boy she was clinging to. She recoiled violently. Shirou's only response to her lethal fluid was a snore. HE WAS STILL ALIVE.
Serenity couldn't help but giggle quietly, the sound foreign even to her own ears. Usually her laughter was sweeter but loud- meant to draw attention. It was a scripted sound meant to be used as honey to bait a trap. This was softer and solely from the heart. Faint enough that nobody would hear it in a crowded room.
Serenity reached out tentatively, placing her bare hand on Shirou's cheek. Her heart stopped as she felt his skin beneath her palm. It was warm and soft, a stark contrast to the coldness, the only feeling she had ever known. She waited for the tell-tale signs of death- the convulsions, the sudden stillness. Nothing happened. His breathing remained deep and even. His pulse remained strong. He was alive. He was alive and she was touching him.
The realization washed over her in a wave of pure, unadulterated joy. Her hand began to shake with the weight of what she had just felt. The tears grew in number until they were a river, trailing down her face and onto his bare skin. And every single one of them left him unaffected. It didn't make sense. She didn't care. She had never felt so alive, so human. Was this what happiness was like?
Her trembling hand traced the contours of his jawline, feeling the softness of his skin beneath her fingertips. Each stroke sent shivers of excitement through her body. She had killed so many people with that same hand, but now it brought her something she had never experienced before—contact without the taint of death. The warmth of his flesh seeped into her soul, filling the void that had haunted her for centuries. She finally had a chance to love someone.
Serenity had never heard a word from Shirou Emiya's mouth, she had never even seen his eyes. She knew nothing about him. But she knew that he was perfect because he was not dead. It didn't matter to her if he was the world's greatest evil or a child who could not walk without assistance. All that mattered to her was that he was alive and she could touch him. She loved him for that and everything else, no matter what it was, could not change that. Her Master was irrelevant, his servant was irrelevant, nothing mattered but him. The person that she could freely touch.
Her breath was heavy and hot as she climbed over him. She felt his warmth and she craved more. Her body pressed against his, feeling his heart beating in sync with hers. She was so close to him, she could feel the heat of his skin, the smell of his sweat. It was heavenly. She curled around his chest, her legs tangling with his. The fabric of their clothes was an annoyance, a barrier between her and the feeling of his bare skin.
Her head was nestled in the crook of his neck, her cheek against his skin. She could feel the beat of his heart, the rise and fall of his chest as he breathed. It was like music to her, a symphony she had never been allowed to hear before. Her hand slid up to his shoulder, feeling the muscles there. She had killed men with shoulders like that. Men who had loved her and never knew it was a lie. But Shirou was different. She didn't need to lie to him. She was happy, for the first time in a long time. And she would do anything to keep it that way. She hated the lack of feeling in her legs, the scratchy fabric of both her and Shirou's pants rubbing against each other.
Her body fit perfectly against his, like they were two puzzle pieces made for each other. She felt safe, protected. For once, she was not the one in control, not the one with the power of life and death. She was just a girl, holding onto a boy she had never met, feeling alive for the first time. The darkness of her past was a distant memory, drowned out by the warmth of his chest. She had never felt so alive. Why did it still feel so cold? She finally got to be happy with someone she could touch... and there was still something in the way... and she hated it.
With a gentle force, she began to peel the fabric away from their bodies. It was a strange sensation, the material sliding against her skin. She had never felt the need to be naked with someone before. It was always about the job, about getting close enough to kill. But now… it was different. She didn't want anything to come between them, not even the clothes that separated them. The sound of fabric tearing filled the quiet room as she removed her own clothes, feeling the cool air kiss her skin. It was a feeling alien to her.
Serenity took a moment to admire his form, his chest rising and falling with each breath. She turned her gaze to his still clothed legs. That was unacceptable. With a gentle tug, she began to pull at his shorts, sliding them down his legs, revealing his bare skin. She felt a sense of awe and a strange hunger she couldn't place, a longing for him. The only man she could ever have. The fabric hit the floor with a quiet smack and she immediately clamored back to him.
Once she had removed his pants, she laid back down on top of him, her breasts pressing into his bare chest. His length pressing up against her thigh. She pulled the blanket over them, enveloping them in a cocoon of warmth. She would not let him go cold in the night of the winter. She nuzzled her face into the crook of his neck, breathing in his scent. It was a scent she would never forget. She wrapped her arms around him, holding him tightly. This was all she wanted, all she needed. To be close to someone, to feel their warmth, to finally be a human.
Her legs slid around his, entangling with his. The feeling of his skin on hers was intoxicating. She had never felt so alive, so real. Her eyes grew heavy and she felt her consciousness slipping away. She fought it for a moment, not wanting to miss a second of this precious time. But the warmth and the comfort were too much. She let herself drift off, her body relaxing fully against his. Her breath grew shallow and even as she fell into a deep, peaceful sleep. Her arms remained wrapped around him, her hand resting on his chest, feeling the steady beat of his heart. This was paradise.
"Assassin!?" Shirou woke up to the sound of shouting. "What do you want from my master!?" It was Saber, his weary mind managed to connect the dots as his eyes flickered open.
A face was leaning over his. An unfamiliar one at that, not the one he heard shouting. Her face was a slightly darker tone, with wide purple eyes staring down into his own as they slowly flickered open. Purple hair hung like a curtain around her face, obscuring his vision of anything but her. She was pretty. Her face was separated from his by just a few centimeters, the tips of their noses touching. The smile on her face stretched ear to ear as she looked at him. Shirou found it more than a little unnerving. "Hi," the strange girl on top of him whispered. She chewed on her lip nervously as she awaited his rejection.
Shirou wanted to scream. What the fuck was happening? Why was there a strange girl on top of him… "Can you get off of me?"
She shook her head violently, her soft hair brushing across Shirou's face as she did. "..." She had said something quietly, but Shirou missed it over the sound of Saber's yelling. "What do you want from my Master, Servant!?
She was a servant? Shirou's eyes went wide as he stared into her enchanting purple eyes. Why was he not dead then? Why was she in his bed? What the fuck was going on? He had to be dreaming. None of this made any sense.
"What's Shirou done this time…" Rin yawned as she entered Shirou's room still clothed in his pajamas. Her eyes drifted to Shirou and she gasped. "Aren't you going to introduce me? You didn't tell us you were having a girl over," Rin quipped.
"That girl is a servant!" Saber insisted. "She's using Shirou as a hostage… I think."
Was that what was happening? He didn't feel like a hostage. A little uncomfortable maybe, but she looked nice. She was laying on top of him gently, not threatening him. Her womanly chest pressed against his broad one and her thigh around his… wait… "Am I naked?" His voice was barely a whisper.
Serenity's face glowed with a light red sheen as she nodded almost imperceptibly. "Why?" he whispered, his face even brighter than hers. Serenity ducked her head against his neck, unable to meet his eyes. How did one explain that they needed to feel he was alive? To touch someone for the first time. She couldn't, not concisely. Not like this… "comfortable," she settled on.
"HELLO? Anyone there?" Rin shouted. Shirou, slightly less restrained now with her face no longer obscuring his vision, turned to look at her tapping his foot impatiently.
"Rin?"
"Oh good!" She sneered, her voice dripping with sarcasm. "Someone is finally awake! Care to tell us what is going on?"
Shirou flushed as if he was caught doing something wrong. "I err- uh don't know?"
"Then tell me Assassin who are you and why are you in his bed? Is he your hostage?" Rin demanded sliding her attention away from Shirou and back to the person snuggled on top of him.
The only reply the strange servant gave was to rub her nose against Shirou's neck.
"I'm speaking to you!"
"…"
"Get off him and talk to me!"
The purple-haired girl shook her head against Shirou's neck, a faint "no" escaping that only Shirou heard.
"Honestly!" Rin snarled, her patience completely deteriorated. It was probably safe enough. She stomped towards Shirou and the hussy intent on ripping them apart. She wasn't hostile, just a lazy mute whore. Her hand reached for the girl's shoulder intent on pulling her off of him herself if she had to.
"No!" Serenity screamed, desperately grabbing Shirou's shoulders and spinning onto her side, dragging Shirou around with her. She pressed up against him once again, trapping his length between their stomachs. She peeked over his shoulder as Rin's hand came down on Shirou's back instead of hers and exhaled lightly in relief. "Do not touch me!" Serenity warned. She didn't know much about Shirou's servant or ally, but she would not risk killing them unless Shirou told her to. Then she would do so with glee in following his command.
Rin leapt back as her hand scraped against Shirou's back, alarmed at both touching the bare skin of the boy she liked and the warning from Assassin. She held her hands up defensively. "Okay I won't! Geez, can you at least get off of Shirou and have an actual conversation."
Assassin glared at Rin over Shirou's shoulder, watching her warily as she continued to cling to Shirou. "Err… What exactly do you want from us… from me?" Shirou might be a bit dense, but he was still capable of recognizing that Assassin was clearly most interested in him. That was obvious with how his naked penis was pressing against her belly.
She tore her eyes from Rin the moment he spoke and her soft violet eyes locked onto his. She smiled at him. "A hug," she insisted shyly.
"Uh… okay?" He awkwardly wrapped his arms around her. Assassin beamed at him as her arms came around to caress his back. She pulled him towards her in a very tight grip. His front slammed into hers and was pressed directly into her. She sighed in contentment as her face pressed into the crook of his neck. Her top leg even came around to wrap around him, her foot resting against the small of his back. She was warm and soft… His heart throbbed as did something else.
Saber said something but Shirou missed it… he was a little distracted. Shirou thought that was more than justified with how the very pretty Assassin was pressing up against him… and the fact that they were completely naked. His cock, now rock hard rested against her hard abs and the head of it pressed up against something… was that the underside of her breast…? His face turned as red as his hair. "Err, can you let me go now?" His voice was strained as he tried to ignore his growing hormones.
Serenity shook her head and mumbled no, but did at least relax her grip slightly.
"Um… why?" He mumbled. "We aren't going to hurt you… If that's what you're worried about. I promise."
"I am finally happy here."
Shirou blinked owlishly. What did that mean? What about him made her happy? What…?
"Who. Are. You. And. Why. Are. You. Here?" Rin spoke slowly with emphasis on each of the words. Assassin once again ignored her and focused solely on Shirou.
Shirou wasn't dumb enough to miss Rin's memo. "Can I ask for your name?"
Assassin flinched slightly but met his eyes once again. "I am one of the Hassan-i-sabbah, the Old Man of the Mountain, this one is called Serenity. " Shirou had no idea what those titles meant. Fortunately, Rin was there to explain for them.
"Hassan? I suppose that isn't too surprising. They were an ancient guild of assassins and the previous grail wars have all had a Hassan summoned in the class of Assassin. Makes sense that this one would be the same… I can't say I recognize the title of Serenity though."
"I knew it!" Saber blurted out. "I warned you that your bounded field wouldn't be enough to stop an Assassin!" She flushed at her sudden outburst.
"Why are you here Serenity?" Shirou's cheeks flushed. "Err- can I call you that?"
Serenity nodded eagerly. "Of course, you can call me whatever you like."
"Serenity," Shirou tested her name out. It suited her. "And why are you here?"
Serenity shifted against him and her eyes drifted down to look at his broad chest. Shirou bit his lip to stop himself from groaning in pleasure at her movement. "Two nights ago… my master ordered me to come here and kill you…"
Saber brandished her sword. "You dare to threaten my Master, I will remove your head!"
"Saber stop!" Shirou shouted before she could do something stupid. "I am still alive, so evidently she changed her mind. Let's hear her out first!" He was more than a little on edge, being in bed naked with such a tempting vixen.
"I came here to kill you two nights ago… but you didn't die."
"What do you mean by that?" Rin demanded. "Somehow, I doubt he fought you off without remembering it."
Serenity was silent, unwilling to acknowledge anyone but Shirou. He sighed wearily. "Can you please answer Rin's question?" He asked. "I also want to hear what you have to say."
Serenity nodded and leaned her forehead against Shirou's. He could see tears glistening in the corner of her eyes. "My body is toxic. A single touch from me had killed every person I've ever come into contact with… No matter how much I wished otherwise… Until you." Her hand gently caressed his cheek as Shirou layed there paralyzed by the information received. He was immune? After her entire life of suffering? He could… save her.
"Shirou is immune to your poison?" Rin questioned.
"Yes," Serenity confirmed. "He is the only person who I've ever been able to touch without it resulting in their death."
"Ever?" The word escaped Shirou's lips before he had even thought about it for a moment.
Serenity nodded. Shirou's mind was a whirl. How sad was that? Had she really never had anyone? How did she live like that? The threat of death lingering over everyone she got close to, one accident was all it took to end things in disaster… until him. He could save her from this life of misery… wasn't that why she was here? Like this?
"You can stay here. I won't let you be alone anymore," Shirou swore. His arms wrapped around her pulling her into another hug. She squealed in joy. Shirou meant it full-heartedly. He didn't have to know more about her other than that she needed to be saved to make that offer… although having her naked and very womanly body in bed with him certainly didn't hurt.
"I don't think that's a good idea," Rin shut him down immediately.
"I couldn't agree more!" Saber nodded eagerly.
"I'm not going to-" Shirou protested.
"I'm not telling you to be heartless, Emiya," Rin cut him off coolly. "I am telling you that it's not safe. She will hurt you."
"I will never hurt him!" Serenity's voice was low yet firm.
"You say that now, but what about when you are forced to choose between your Master and Shirou? Shirou and the Grail?"
"I will choose Shirou."
"And why should we believe that?"
"Atrum Galliasta."
"W-What?"
"That is my master's name. My wish for the grail was to find Shirou. Is there anything else you need to know?"
"No. That's all Serenity," Shirou cut in before Rin could demand more. "I trust you, and know that you won't turn on us. I won't let you suffer anymore."
"And if you don't have a choice?" Rin pressed on, ignoring Shirou's objection. "What if your Master used a command spell to force you to kill Shirou?"
Serenity glared at Rin fiercely. "Then I'll kill myself before I harm him."
"Don't do that," Shirou protested automatically. "I am not worth that."
Serenity looked at Shirou and cupped his cheek. "There is no point in me living without you."
"That's not-"
"Drop it Shirou," Saber growled. "She will kill herself if she's forced to turn on us, or I will cut her down right here." Rin nodded in agreement with her statement. It was objectively the correct decision, even if Shirou hated it. Even Serenity was eager to nod in agreement with her statement.
"I'll stop her," he swore to himself under his breath. "I won't let her die for me." Serenity's sad smile and Saber's stern frown made it clear that he wasn't as quiet as he had hoped. Thankfully neither of them said anything.
"Fine," Rin grumbled. "She can stay, what do I care? I don't want her near me or Archer though, if I think she's dangerous, he will cut her down."
"I have no interest in anyone but Shirou," Serenity affirmed.
"With that settled, can you please get off of Shirou?" Rin asked, despite the polite words, her frustration was apparent.
Serenity didn't move. Shirou sighed. "Can you please get up… so I can get dressed? I need to make breakfast."
Serenity pouted at him and Shirou was tempted to kiss that look away. She wanted that right? He shook his head lightly to clear the distracting thought from his mind. "I like touching you." His penis throbbed in response to what was no doubt intended to be a more innocent statement than his perverted mind conjured. He needed a cold shower.
"And you can- err… touch me, but maybe a little less during the day? I'll hold your hand whenever you want…" His cheeks flushed as red as his hair. "I just… maybe a little less… I have to… make breakfast! Yeah!"
Saber nodded vigorously in agreement. "Indeed, the time to dine has already arrived! We must make haste to the kitchen!" Her stomach growled loudly to echo the sentiment.
Serenity's eyes roamed Shirou's face anxiously before she gave a slight nod. She hugged him one final time, and then grabbed his right hand in hers. She squeezed it tightly and interlocked their fingers. She rolled to the side, away from him for the first time in hours. The blanket that was wrapped around her back came with her… pulling it off of Shirou. "This is… nice," Serenity conceded as she squeezed his hand and leaned against his shoulder.
Without anything pressing his cock up against his navel, it snapped down to stick out straight ahead, brushing over her stomach. The large and hard shaft fully erect and completely uncovered now.
"Eek!" Rin squealed in horror at the sight of his manhood. "Saber and I will be waiting for breakfast! You two get dressed!" She shrieked and grabbed Saber's arm, dragging her out of the room and leaving Shirou alone with the potentially dangerous Serenity.
The two of them were left in the room with the silence ringing loudly. Serenity's eyes had never left Shirou's, not even when she knew she was being stared at by Rin and Saber. Now that they were gone, Shirou was much more conscious of Serenity's eyes on him.
"We should get dressed," Shirou murmured, his eyes drawn to the delicate curves of Serenity's bare body as they stood up. Despite cuddling for the last hour, this was the first time that Shirou really got a chance to look at her. She was breathtakingly beautiful, and the way she looked at him with those violet eyes was like looking into a serene ocean. He felt a strange yearning that he couldn't quite place.
Serenity nodded, and then bent over to pick up her discarded clothes, giving Shirou a full view of her perfect ass. He couldn't help but stare, his eyes tracing the lines of her back, the curve of her waist, and the firmness of her buttocks. The sight was tantalizing, and his breath hitched in his throat. As she straightened up, she caught him staring, and a blush painted her cheeks, but she didn't move to cover herself. Instead, she met his gaze, and for a moment, it was as if she were offering herself to him.
Shirou's eyes widened as she turned to face him, the blush deepening. He didn't know what came over him, but he stepped closer and kissed her, his hands moving to her hips to pull her closer.
Serenity froze in shock, her eyes wide as his soft, gentle kiss took her by surprise. The fear of her toxic saliva didn't seem to phase him, and she felt something strange happening. She didn't feel the usual sickness that came with someone touching her, nor did she feel the compulsion to pull away. Instead, she felt a warmth spread through her body, and her heart raced in a way it never had before.
Their kiss grew more urgent, their bodies pressing against each other, and Shirou's hand slipped up to cup her breast, his thumb brushing against her nipple. She gasped into his mouth, and the sound was like music to his ears. He broke the kiss, looking at her with concern. "I'm sorry, I didn't mean to-"
But she silenced him with another kiss, her own hands moving to wrap around his neck, pulling him closer. Her fear had vanished, replaced by a desperate need to feel him, to taste him, to touch him. She could feel his cock pressing against her stomach once again, and she pushed herself against him, feeling the heat and power of it.
They stumbled backward, and he sat down heavily in the chair she had indicated earlier, pulling her onto his lap through their interlocked lips. She straddled him, her legs on either side of his hips, and she took his cock in her hand, feeling the velvety smoothness of it, the heat, and the pulse of his arousal. He groaned against her mouth, and she felt his hands on her back, moving down to cup her ass, pulling her closer.
Their kisses grew deeper, more intense, and she stroked him, feeling the blood rush through his veins, feeling the beat of his heart under her palm. He was alive, and she was alive, and it was all because of this strange, beautiful connection between them.
"Serenity, should we really be doing this?" Shirou murmured against her lips, his voice thick with desire.
"I need this," she mumbled as she jerked her hand up and down his penis. "My role as an assassin was often to seduce a target... or pose as their fiancé. Occasionally I would do this with gloves... but I've never actually felt one in my hand before... It feels so good. Please... Shirou," she begged.
He didn't need much encouragement. He nodded, and she could feel his heart racing through their interlocked fingers. She carefully straddled him, aligning their hips. With a look of both excitement and fear, she sank down onto his cock. Shirou's eyes widened and his mouth fell open as he felt her warm, tight wetness envelop him. It was nothing like what he had ever felt before, and he knew that she felt the same. She was so tight, so perfect, and he didn't want to move.
"How is it?" He managed to ask, his voice strained.
"It's heavenly," she whispered, her eyes never leaving his. She started to bounce gently on his lap, her movements slow and tentative at first, as she grew accustomed to the feeling of him inside her. "Everything I've dreamed of and more."
Shirou groaned, his hands moving to her hips to help guide her. He watched as she grew more confident, her eyes fluttering closed and her cheeks flushing a darker shade of pink. Her breasts bobbed with each bounce, and he couldn't resist leaning forward to capture one of her nipples between his teeth.
Serenity gasped and arched her back, her eyes snapping open to look at him in surprise. He grinned, his teeth grazing her sensitive flesh before he soothed it with his tongue. She moaned and rode him faster, her hands now in his hair, holding him to her.
"Shirou... I can't believe this... it's... it's everything I've ever dreamed of... and more..." she panted out, her voice breathy and full of passion. "I love you so much!"
He kissed his way up her chest, capturing her mouth in a deep, soul-searing kiss as she continued to bounce on his cock. He could feel her walls tightening around him, and he knew she was close. He whispered against her lips, "I love your body, Serenity. You're so beautiful... so perfect... I've never felt anything like this before..." He couldn't reciprocate her feelings, but he could be honest with her at least. This was the most incredible feeling of his life… and his love would save her.
Her eyes widened at his words, and she threw her head back, crying out as she came, her body convulsing with pleasure. He loved her body? How? Her body was repulsive. Toxic and deadly. No one could think it was beautiful... but Shirou did? Shirou, who was still inside her, still filling her up and making her feel alive, thought she was perfect? The contradiction sent her over the edge, and she felt her walls tighten around him, milking him for everything he had.
And he had quite a bit. With a final, deep thrust, Shirou came inside her, his warmth spreading through her body and mixing with her own pleasure. Her eyes rolled back in her head, and she couldn't stop the moan that tore from her throat. She had never felt anything so exquisite before. Her whole life had been a series of false happiness, of touches that corroded, but this... this was something she had never even dared to dream of.
They stayed that way for a moment, just catching their breath before the insatiable hunger for contact overwhelmed Serenity once more. She broke the silence by shoving her tongue back into Shirou's mouth, their kisses growing more fervent and deep as she rolled her hips against his, the warmth of his cock still nestled inside her. The sensation was indescribable, a feeling she had never been allowed to experience, and she craved more.
Her movements grew more urgent, and she pushed herself up slightly, grinding against him as their kiss grew more passionate. Shirou's hands tightened around her waist, and he could feel her body quivering with need. He knew he had to give her what she wanted, to let her feel alive, to let her know that she had someone now.
With a groan, he stood up, lifting her effortlessly and laying her down on the tatami mat. He slid out of the chair and followed her down, never breaking the kiss. He settled between her legs, his cock still hard and demanding more. Her thighs wrapped around his waist, and she pulled him closer, her nails digging into his back.
Serenity's eyes fluttered open, looking up at him with a mix of desperation and adoration. "More, Shirou. I need more of you," she begged, her voice a hoarse whisper.
Shirou didn't hesitate. He thrust into her again, the feeling of her wet warmth enveloping him sending shockwaves through his body. He watched her face contort with pleasure, her cheeks flushing a darker shade of pink as she moaned his name.
"Shirou!" she cried out. Her legs tightened around him, her heels digging into his ass as she urged him deeper, her hands roaming over his back, feeling every muscle and scar.
He began to move, his hips pumping into her with a steady rhythm that had her arching off the floor. Each thrust sent sparks of pleasure through her, and she could feel another orgasm building. She had never felt so alive, so human. Her body was usually a weapon, a tool, something only dealt in death, but with Shirou, it was something else entirely. It was a vessel for love, for pleasure, for connection. She found she preferred this purpose.
Her legs tightened around his waist, trying to pull him closer, as if she could absorb him into her very being. She knew it was impossible, that he couldn't fill her up enough, but she needed to try. Every time he pushed into her, she felt like she was coming home. Her body was singing with sensation, each stroke of his cock sending her closer to the edge.
"Serenity..." Shirou murmured, his eyes never leaving hers. "You're so beautiful... I've never felt anything like this before..."
"Neither have I..." she panted, her nails digging into his back. "It's all because of you... because you didn't die when I touched you... because you're different... because you're mine… I love you!"
Her words were punctuated by gasps and moans as she felt the climax approaching. Her whole body was trembling, her muscles taut with need. She had never felt so alive, so full of passion.
The orgasm hit her like a wave, crashing over her and making her scream out his name. Her inner walls spasmed around him, her body writhing beneath his. She had never felt anything so intense, so all-consuming. Shirou's eyes widened, and he moaned, his thrusts becoming more erratic as he felt her tighten around him.
He didn't stop, though. He kept moving, driving into her as she rode out the waves of pleasure. Each thrust sent another jolt through her, each touch of his skin against hers sending her higher. She could feel her body responding to him, her nipples hardening further, her clit pulsing with each beat of her heart.
And then she was there again, another orgasm cresting over her. She threw her head back, her eyes squeezed shut as she screamed out his name. Shirou's eyes were on her, watching her face contort with pleasure, his own body tense with the effort of holding back his own climax.
"Shirou... I'm... I'm going to come again..." she warned, her voice trembling.
He leaned down, capturing her mouth in a deep, hungry kiss as he increased his pace. Her body responded instantly, her hips rising to meet him, her legs tightening around him.
Her climax was a crescendo, a symphony of pleasure that left her breathless. She could feel her muscles clamping down on him, her body shaking with the force of it. And still, he didn't stop, his hips moving in a relentless rhythm that had her panting and begging for more. The tightness as she came squeezed Shirou's shaft. With a groan, Shirou came inside her, filling her with his warmth. She felt his cock pulse within her, and she knew she had done her job. She had brought him pleasure, and had made him feel alive, too.
They lay there for a moment, their breathing ragged and their hearts racing in unison. Then, as if driven by an insatiable hunger that only grew with each touch, Serenity spun around her eyes shimmering with a new desire. She took his now-softened cock into her mouth, tentatively at first, savoring the taste and the feeling of him. It was something her targets had frequently demanded of her, but none of them were Shirou so she had refused them all. But with Shirou, she could indulge, and she reveled in the knowledge that she could bring him pleasure without causing him harm. And that he could make her feel so... alive.
Shirou watched her with a mix of awe and arousal as she crawled onto his stomach, her mouth hovering above his cock. He could feel her hot breath against him, and it made him shiver with anticipation. She took him into her mouth, her tongue tentatively exploring his shaft. He felt himself harden instantly, his body responding to the sensation of her velvety softness.
Her movements grew more confident, her cheeks hollowing as she sucked him deeper. She seemed to revel in the power she had over him, the way his body responded to her touch. He couldn't help but groan, his hands finding their way into her hair, gently guiding her as she took him in and out of her mouth. Her eyes never left his, a silent communication of her desire and need for more.
Meanwhile, Shirou lifted his head to taste her, his tongue darting out to flick against her clit. She gasped, her hips jerking down towards his mouth in response. He explored her folds, tasting her sweetness and feeling her warmth against his face. Her thighs tightened around his head, her hips bucking as he found the right rhythm. He could feel her getting wetter, her body begging for more.
"Oh, Shirou..." she murmured, her voice muffled by his cock. She took him deeper into her mouth, her cheeks hollowing out as she sucked harder. He groaned against her cunt, the vibrations sending tremors through her body. Her orgasm was building again, and she could feel it coiling in her belly like a living thing, ready to pounce.
As Shirou's tongue swirled around her clit, she felt her body tighten, her muscles clenching in anticipation. She could feel the warmth spreading through her, a warmth that was not from her usual deathly touch, but from the love she felt for Shirou. Her breath hitched in her throat as she felt herself come apart, her body shaking with pleasure. She moaned around his cock, her eyes squeezed shut as she rode out the waves of sensation.
He didn't let up, his tongue and teeth working in harmony to drive her over the edge. She screamed, her body convulsing as she came, her pussy clenching around his tongue. She could feel his cock pulse in her mouth, and she knew he was close. She sucked harder, eager to taste him, to bring him the same pleasure he was giving her.
And then he was there, his hips jerking as he came, his hot seed filling her mouth. She swallowed greedily, the salty taste mixing with the sweetness of her own arousal. She had never tasted something so incredible. She felt another orgasm building, her body responding to his release. It washed over her, leaving her boneless and panting.
They lay there for a moment, their breathing heavy and their bodies slick with sweat. Then, with a growl of need, Shirou rolled them over so that he was spooning her from behind, his hard cock pressing against her ass. He reached around to grab her breasts, his thumbs flicking over her nipples as he pushed himself into her wetness.
Her pussy was soaking, begging for his touch, and he gave it to her, filling her up as she moaned his name. He moved slow and steady, his hips rocking against her, their skin sliding together in a delicious friction that made her toes curl. She arched her back, pushing her ass against him, silently urging him to go deeper, to touch every part of her that had been denied for so long.
Serenity's body was a symphony of sensation, each stroke of his cock sending waves of pleasure through her. Her breasts felt heavy and sensitive in his hands, her nipples tight and aching for more. Her pussy clenched around him, desperate to keep him inside her, never to let him go.
Shirou's hands roamed over her body, exploring every inch of her smooth skin. He cupped her breasts, squeezing gently, then slid down to her hips, holding her in place as he thrust into her. She could feel his heart beating against her back, the steady rhythm matching the pace of their lovemaking. She was overwhelmed by the sensations, after so long without feeling the touch of anyone, feeling Shirou's hand all over her everywhere was driving her insane.
Her face was flushed, her eyes half-closed as she moaned and gasped with each movement. Her pussy was tight around him, and he could feel her walls quivering with the beginnings of another orgasm. He leaned down, whispering in her ear, "I love your body Serenity. It's so perfect. You are so incredible... You deserve to be cherished, curse or no."
The words sent a shiver down her spine, and she nodded, her eyes rolling back in her head. Maybe her body wasn't so despicable? Shirou loved it at least. And he was the only person whose opinion mattered. She could feel the climax building, the pressure growing inside her with every stroke. And then it washed over her, a tidal wave of pleasure that made her entire body convulse. She screamed his name, her pussy clamping down on him as she came.
Shirou groaned, his own orgasm close behind hers. He reached around to rub her clit, his thumb circling the sensitive bundle of nerves as he drove into her. She bucked against him, her body shaking with the force of it.
And then they were both there, coming together in an explosion of sensation. She could feel his hot seed fill her up, and she reveled in the feeling of being claimed by him. He kissed her neck, his teeth grazing her skin as they both panted and gasped for air.
They lay there, entwined, their hearts beating as one. Serenity's body was a map of sensation, every inch of her skin tingling with the aftermath of pleasure. Shirou's cock was still inside her, his arms wrapped around her waist, holding her close.
"I love you, Shirou," she whispered, her voice hoarse from screaming.
"I know," he murmured back, his voice filled with a gentle certainty. "And I'm never going to let you be alone again."
Shirou's eyes snapped open at the sudden realization that they had spent over an hour lost in each other's embrace, completely oblivious to the ticking clock. He could feel Serenity's body warm and relaxed against his, her breaths steady and content. He couldn't help but smile at the thought of how much she had changed in such a short time. She was no longer the woman who cursed everything she touched, but once that was happy. One who had been saved by him. He had saved someone!
"Saber's going to kill me if we don't get up soon," he said with a chuckle, his eyes drifting to the clock on the wall. It was already past breakfast time, and he knew the stoic servant would not be pleased with his neglect of duty.
But as he felt his cock stir to life again inside her, he decided that a few more moments of bliss wouldn't hurt. Saber could wait. He pushed aside the guilt and allowed himself to get lost in the feeling of her body against his. Her legs were still tangled with his, her soft, round ass pressing against his pelvis, inviting him to move deeper. "I think... I could learn to love you."
A/N:That was cute... at least the idea of it. Time to dump some cold water on everyone's head. This story fundamentally can not have a remotely happy ending.
Hassan of the Serenity is the servant of Atrum Galliasta- that was my decision, and a horrible one. He has a literal child compressor! Shirou obviously won't abide by that- and when he finds out, he will go after him, regardless of his self-interest.
Making her the servant of anyone but Rin or maybe Illya would result in the same outcome on a slightly more drawn out scale. I did Atrum because the original prompt requested a Master like Celenike from Apocrypha and he was the closest to the bill. I should have changed it but whatever. So Serenity's master quickly dies, but she has independent action so at least she has a few more days!
Okay, but let's pretend she can last until the end of the Grail War. In the impossible scenario where Shirou wishes to incarnate her, what happens? Saber would still be gone and without Saber, Avalon loses it's potency. Maybe Shirou doesn't die but he would at least be somewhat affected and they would have to limit contact.
So fine, you made it to the end and it's just a short-lived experience of bliss for Serenity to cling to... except, that is not how Hassan of Serenity works. Serenity's interlude in FGO is cruel. Paracelsus makes this claim:
"Her Spirit Origin is somewhat different from ours. Even if SHE were to be summoned once again... Those records would never be carried over from the throne. Only when she gains love, that is. The Hassan of the Serenity who fell in love will never be summoned again. That Hassan shall sleep for eternity, and carry those emotions with her."
Yeah, Serenity is fated to never remember happiness when she finds it, but be replaced by a different her who hasn't found love if she gets to be happy. Only the summons where she is happy does she not get to remember. So uh...
I've seen people question why this is, why Serenity specifically, but honestly I think that is a pretty easy question to answer. The Throne of Heroes is the records of the world, engraved with how humanity remembers legends and the mark they left on the world. Serenitý's legend is that of the poison girl- one who kills everything they touch and never found happiness.
Everytime a heroic spirit is summoned, it's a copy from those records, and when the summoning is over, that record is updated with the new data from the summoning. Even LB Servants like Anastasia are part of PHH Anastasia's record. Most of our servants remember their previous summonings.
There are a few exceptions though, one of the most notable being Medea. The Caster from FSN never once references it in FGO- she never gives hint of her happiness with Kuzuki. Why? For the same reason that Serenity can never be happy. Her ending with Kuzuki is a contradiction to the legend of the Witch who is most famous for betrayal and dying alone. Characters like Sasaki, Artoria, EMIYA, Cu all remember FSN. Mordred, Fran, etc. remember Apocrypha. Lots of characters remember extra. Heck, they even have Gilles remember Zero rather explicitly based on my room dialogue.
All of your exceptions are characters whose character development runs in opposition to how humanity remembers them so the throne is not able to update the record. So Serenity can never remember happiness.
Usually, I work on like four prompts at a time and bounce between them when I get stuck, but this one consumed me. I got stuck lots cause it's depressing and couldn't focus enough to work on another. This was not supposed to be the next prompt published, but it became it because I didn't want to wait a weak for editing like usual, but just move on. This was supposed to be a Ritsuka/Tenochtitlan one. Next time, I suppose.
Thank you for the prompt, it was a fucking blast to plot out, but wow writing it was hard once I realized there was no hope of Serenity ever being happy. Hopefully the writing quality was still decent.
Saber was super off here and mute too much, but juggling a private interaction and two other characters was difficult. This is Fate route adjacent so Archer was injured. Shirou's motivation in accepting Serenity I'm not sure came off as I wanted it to. Shirou is trying to save Serenity from her life of misery- it's less romantic love, and more lust the combination of loving the idea of saving her. That would shift in the like two days they have together. The whole calling her the Knight of Betrayal thing was because I think people should be wrong in guessing historical figures more, and initially I had a scene planned with Saber blowing up at being called that.
Anyways thanks for reading! Hopefully it wasn't too much of a slog. Leave a like, Subscribe to this and my account as I publish one-shots pretty regularly too. And comment more prompts below! Preferably less depressing ones! (But seriously, this one was fun and I like the very character/plot driven ones)
