This idea just appeared out of nowhere, and I just couldn't sleep without putting it out there. To set expectations, there will be a lot of kinky smut and light cheating although that could change in the next part. Oh, and hate sex, a ton of it probably.

I do not own anything related to the Fate franchise.

It was quite late at night when Musashi rose from her futon, fully awake and yet longing for sleep. The Japanese inn was silent with only the tune of crickets from outside creating substance to the atmosphere.

Yet her thoughts were far from the insects or the inn.

Chaldea's Master and his Servants had taken their journey across Japan and arrived at this for a brief vacation, but everyone except Musashi could not relax. It was a hopeless predicament.

Her relationship with him had always been close to the point that they were inseparable. They knew each other's likes and dislikes. They trained together. They pulled pranks on Heroic Spirits. They called each other by first name. Yes, they were the best of friends. However recently, Musashi's eyes wandered far deeper on her Master's being than they did before. When he smiled, it felt like butterflies in her stomach. When he leaned against her, an aggressive pounding erupted in her chest. The heat she felt resonated in her being.

The swordswoman then realized that her feelings were not entirely casual, not anymore. They were a sign of intense infatuation and adoration. Love that could be found in a young maiden's heart started to develop within her. For a master of the martial arts, this was laughable, an unlikely development, but she saw it as if it were a beautiful thing to find from their friendship.

He was sweet, kind, courageous, and confident, all the qualities she found irresistible. Not to mention he was a handsome man, although there were plenty handsome studs in Chaldea, the Master had a unique charm to him which she couldn't quite pinpoint. But if she were to guess, it would be his boyish traits coupled with his hidden wisdom which shone amidst the direst of situations.

The sounds of the sliding door opening closing rang through the hallway as she left the room to make way for the hot springs. It was very late at night. No doubt nobody would dare to be out this late. This was the perfect chance for her to relax and calm down her feelings albeit temporarily, and what better chance to do that than soaking her entire body under the stars of the night sky.

Since it was so late, the inn allowed only the mixed baths to be open. That did not deter the beautiful swordswoman one bit however. Besides, there were no other guests around.

She released the pins holding her hair up and let the bundle cascade down around her shoulders and her back. It was only tradition to come inside the baths after putting your belongings away. Not doing so was considered disrespectful. The woman parted ways with her obi, allowing her to spread her kimono wide to reveal her flawless yet toned body. Not a hint of undergarments were found inside for Musashi never believed in such frivolous accessories.

Wrapped in towel, she nearly jumped in surprise as the door from the baths opened.

"Oh, hello…" called out the faint voice of a woman. From the other side of the changing room, the swordswoman felt herself calm down as she recognized that it was only the blonde saint, Jeanne d'Arc. Vestiges of sweat and bathwater could be glimpsed down her shoulders. Her tightly wound towel looked hastily put together as she looked desperate to keep it up. Blushing, Jeanne smiled and asked, "Are you getting in? It's quite late already."

Musashi couldn't help but blush from her presence as well. "Yeah… I won't be long. Are you okay? You seem flushed."

"I-It's nothing. Please don't mind it! See You." The saint scampered away from the scene to change.

Left with a questioning look, the swordswoman wondered why she was acting oddly but decided to forget it for now. Her hand latched onto the door and slid it open. A veil of steam obscured the scenery. Before getting in, she washed herself in silence in one of the stalls along the walls. Never had her hair felt so long in her back than it did now. It was no wonder she always kept it up for it proved to be quite a nuisance in battle. Once she was fully wet, her feet stepped on the slick, stone walkway towards the pool of water.

The bright moon hovered high above the clouds. She could hear the gentle rustle of leaves from the surrounding tree branches beyond the wooden fences. All around her, mist floated about, circling the large stone boulders scattered across the pool. The water was at the right temperature. It warmed her body up and sent pleasant tingles across her skin. She could just about feel her muscles untangle and loosen. Her voice let out a soft sigh as she relaxed against one of the large stones.

It hadn't been a minute until she noticed another person relaxing at the opposite edge, completely lost in relaxation. "Master…?" She called out, but it didn't seem like she was heard. "Ritsuka!"

"Hm?" Finally the young man opened his eyes and turned his focus to the source of the voice. His brown hair was mildly drenched from immersing himself in the water. "Musashi? I didn't notice you coming."

"You came for a soak too?" The woman waded through the water, keeping her body submerged. His sudden appearance made her self-conscious, although she didn't mind being seen at all, it was merely just a reflex. The amount of time they spent together was enough to make them comfortable with each other's presence, no matter what state of undress they were. And so, she rested a little closer on the same edge but not too close.

"Yeah, this place is beautiful at night, so I couldn't help myself." He gazed up as he leaned against the wall. Above was a great swath of stars occupying the night sky. "Plus it's nice to soak in such a place without the chatter of other people. It helps you give a chance to refresh your mind, know what I'm talking about?" He laughed aloud, hiding his nervousness while trying not to stare at her who was already dangerously close to unveiling what was beneath her slender shoulders, though she didn't notice at all.

A heavy beat suddenly disrupted the calm rhythm in Musashi's heart. Her mind played back a couple of minutes. If Ritsuka had been here this entire time, then what about that blonde woman? What had she been doing while their Master was here bathing? Several possibilities ran through her head. Musashi couldn't control the heavy beating in her chest. Before she came in, what we those two doing? What were the two of them doing in this hot spring at night? The wild implications filled every inch of her body with cold sweat. She couldn't stop herself from imagining them being so close… and kissing.

However, no matter what happened between them, she couldn't get mad at him for getting intimate with another Servant, it's not like she held exclusive rights on him. There was no special relationship preventing them from seeking out other people. It's true that Jeanne was an attractive woman, and she couldn't blame him if he fell for her.

That's right, though she wanted to find that anger, something else was boiling inside her, something that was hidden and couldn't be described. It was something that raged downwards and made her legs shiver.

There was a long pause between them. Musashi couldn't broach the subject at all despite wanting to know what occurred. Her patience was growing thin, so she decided to just blurt out whatever came to mind. "Hey…. umm…. How's it like having three beautiful ladies accompany you to this inn, huh? You must be a really lucky guy." She tried to grin. She could hear Ritsuka faintly chuckle and disagree with her, but she was still completely submerged in her own thoughts about Jeanne d'Arc and their Master. The shrinking distance between the two seemed imminent to her.

"It's not like that, really," replied Ritsuka, oblivious to the woman's fidgeting. A blush formed on his cheeks. "If anything, I consider myself lucky since I get to meet you at this hour, Musashi. You look beautiful with your hair down like that."

That snapped the swordswoman from her delusions. She smiled wide and started jabbing him with her elbow. "Hahaha! Are you trying to suck up some brownie points from me, your sword instructor? You'll see that it ain't that easy. But, I'll reward you for your effort. Tell me... who is it that you like, and I'll put in a good word for you."

Ritsuka seemed to have trouble replying to that, so instead, he turned to look at her and only her. His eyes stayed firmly set on her beautiful blues. Puzzled at first, she took notice of his strange behavior, peering through his unreadable expression until she felt her heart start to kick wildly inside her chest.

"Then, you don't have to go far for that. I like you, Miyamoto Musashi," he finally said while still entranced by her perfect face.

There was a slight pause before she broke off their link. The water was disturbed for once as she waved her hands in front as she backed up. "Wait! Wait, wait, wait! This can't be right. Aren't you interested in the other Servants, like Jeanne?"

"Jeanne?" He chuckled. "What's she got to do with this?"

"Well you see…" She was just about to ask why he and the blonde woman were together but couldn't in the end. "But… why me?"

Their distance, which could hardly be considered comfortable to talk in, was reduced by Ritsuka taking strides until he loomed over her. He was only slightly taller than her. But in this instance, he stood high over the woman who was still mostly submerged in the hot water. "Do I really have to answer that?" He asked half embarrassed and half jokingly. "We've always had each other's back throughout all these battles. I lost count how many times you saved my ass. And in Chaldea, we are always goofing around like brother and sister, pulling pranks like that one time we stole Heracles' club or drawing on Ibaraki's face while she was asleep. We created so many fond memories in that small place we call home."

Musashi felt a burden lift from her being as those words resonated within her. How couldn't she? She thought and felt the exact same thing.

"It was all those experiences that are the reason I slowly realized that I've grown to like you tremendously, that I'd be happy as long as I was with you." He smiled. "This may sound weird, but nothing would bring me more joy than to have the rest of our days like this, close to each other, never pulling apart."

"Ritsuka…" Musashi's eyes widened as tears dripped down from the corner of her eyes.

Their gazes coincided again as if they were talking with each other through their eyes. She was overwhelmingly happy. All clouds of doubt were expelled away by her Master's smile.

A large ripple emerged from the surface of the water as she rose. A sakura petal floated from high up and landed not too far and rode the small ebb to settle against a large boulder. Her hands grasped his bare shoulders with her hot breath slowly approaching his dumbfounded lips until they met each other. Their passions became one. "I love you Fujimaru Ritsuka," she said as she broke the kiss for a short while, looking into his eyes. "You are the one who occupies my thoughts from morning till night. If you will accept me as your lover, then there is nothing in this world that would make me happier."

Their next contact sent electric shocks running across their entire bodies. The swordswoman almost fell backwards if it weren't for his strong arms wrapping around her lower back. There was a fire in them which was made even clearer as their mouths intermingled together again. Their scenery faded in the background, lost in their passion. Ritsuka was the first to break the lock in order to breathe, but his partner wouldn't let him rest for long as she wrapped her slender arms around his neck and pulled him into another deep kiss. This time, their tongues boldly left their caves to explore the other's.

Though the older woman was clearly more mature of the two, it was the young man who was on the initiative. As they made out ferociously without stopping, he pressed Musashi forward across the waters until she had her butt sitting at the edge.

"I love you, Musashi. I want you right now. If I were to wait, I would lose my mind." His lips trailed to the side, leaving small pecks just below her ear which only made her whimper quietly and helplessly. His hands still pressed against her hips, patiently waiting for their opportunity.

The swordswoman's arms tightened their clutch against his body, pressing her own well-endowed chest against his own, which only helped to stoke the fire burning within her Master. "Wh-What are you thinking? W-We can't do this here. What if somebody comes in?" Although she let out that unconvincing reason, her entire body was already yearning for more. Feeling something twitch against her bare leg, it only drove her to break even more taboos.

Ritsuka was not dissuaded by his partner's reluctance. On the contrary, it made him even bolder in his advance. It was only natural after all. He had dreamt of this chance for so long. He desired this beautiful samurai more than anything in the world. He'd be embarrassed to admit to her the many times he had to endure their battles while being rock hard due to her alluring presence which was amplified by the revealing outfit she wore as she fought. He would not stop now, not when he was so close. A sultry smile split across his mouth, one that he didn't normally showed, as he let his fingers trail downward her abdomen to her narrow, sticky slit. "You say that…." He whispered against her ear while tracing his finger across the opening of her lower mouth. More of her inner juices dripped and coated his fingers, showing just how aroused she was. "But look at how wet you are already. You are actually quite a lewd swordswoman, aren't you, Musashi?"

"T-that's not true." Despite mouthing her disapproval, her mouth ceaselessly cried out soft whimpers and moans. Her entire body felt like jelly as she could barely hold herself up. Still, she allowed Ritsuka to finger her without any sign of struggle. It was just too good. Her Master's expert fingers were in total control of her desire, and that desire manifested itself slowly. Without a doubt, she wanted nothing more than to have something thick and hard fill her. With a single finger finding its way inside her perverted hole, that desire grew even more.

"What's wrong, Musashi?" Ritsuka's calm smile remained as he held the woman by her back to prevent her from falling as he continued teasing her wet slit with one finger. "Perhaps you want to be seen? Perhaps you want someone to come inside and watch you get fucked?"

"Please… Master…" She dug her nails against his hard back. "Stop… teasing me…"

Seeing the powerful Servant reduced to a mere dainty woman, it compelled Ritsuka to tease her even more. She was just too cute. She was normally so confident and proud, being a swordswoman of great renown and all, but now that she was collapsed and was but a mere helpless morsel to him, he couldn't stop thinking how cute and beautiful she was at this very moment. He wanted to watch her even more. He wanted to see every side of Miyamoto Musashi, the self-proclaimed unbeatable swordswoman.

He allowed her to lie against the stone pavement. With her propped up on her elbows, he continued to slide his finger in and out, eventually adding another to penetrate her wet, yearning pussy. The woman's entrance was so slippery that he had no trouble raising his pace, switching to an even more aggressive stance, resorting to nearly raping her pussy with his fingers. He dug them deep until his knuckles reached the entrance. The intense change made her shriek out loud, throwing her head back. Her body undulated from the movements slamming against her entrance. The feeling of Ritsuka's rough fingers freely going in and out of her made her shiver uncontrollably. She was like putty, only able to moan and watch as his fingers fucked her slick pussy without remorse.

Ritsuka leaned forward and kissed her, wrestling her tongue with his own. He slowed his paced down as he watched Musashi's red face grow slack. A hand found itself groping her ample chest, one of his many great fantasies about her. It was even softer than he imagined. It was as if his hand was being sucked in as he massaged her large breast. A moan escaped the woman's mouth as he curled his fingers around her cherry-like knob which only helped to stiffen her nipples even more until their shape grew fully erect. It did not take long before all these sensations drove the samurai out of her wits, and she exploded a large gush from her reddened vagina. Like clamps, her walls squeezed the young man's fingers hard as they twitched and released wave after wave of pleasure. Ritsuka's hand was covered by a sticky liquid which he tasted before bringing it to the woman's face. She gladly sucked his fingers, leaving no remnants of her own sex in his hand.

"You look… so cute like that." Ritsuka watched as she lapped at his fingers with her tongue.

At this point, Musashi was a total wreck. Her entire body heaved and breathed deep breaths. Sweat and the smell of sex covered her entire body. Her long hair was sprawled all across the ground, a complete dishevelled mess. But Ritsuka was far from done with her.

The swordswoman's eyes looked down from staring at heaven. It immediately caught the sight of her dear Master's magnificent cock. It was by no means the largest she had seen from her time as a ronin in the past, but it certainly sent a clear message on what her Master planned for her tonight, and she was more than willing to comply.

"Now then, Musashi…" He brought his hand to his shaft and jerked it lightly. The mere sight of the beautiful Saber sprawled out naked before him was already more than enough fuel for him. And her bewitching eyes tracing along his body, as if there were hearts patterned in her irises, was a clear sign that she was ready for him. "Tell me what is it that you truly want?"

Musashi could not have thought of anything else but for that stiff rod to plunge into her depths and split her apart. Nothing filled her head more than the thought of her Master fucking her in public with reckless abandon. Her hands reached down to her already sore pussy, for there needs to be a clear message to avoid confusion. If she told him to fuck her there and now, that wouldn't hit the bull's eye for her. If she told him to make love to her as if they had just sealed the deal in their betrothal, although sweet and would be more than welcome that was not what she had in mind at that point. No, what she wanted was the taste of something more ravenous. What she wanted was not the feeling of emptiness that came with the perfection of swordsmanship, but the complete opposite. Rather than freedom from desire, it was the complete dependency on it instead, the total submission of one's body to its primal cravings. Had this been enough to change her Spirit Origin, she would have turned into a wicked Alter who only knew how satiate her desires and forget the way of the sword altogether. But right now, at this very moment, she simply spread her pussy wide as if she wanted to show her Master how much she wanted to reveal herself to him, and conveyed her primal desires with her lips. "Please, Master, use my fuck hole to quench your starving cock," she spoke those words out loud so he could hear them clearly. There had to be a clear message otherwise there would be a misunderstanding. "Rape my pussy until not even my Servant form could withstand it!"

Those words were like captivating music to the young Master, which drove his arousal to the limits, enticing his already hard cock to grow even more. Although he had no experience, he was patient. He had waited for her approval. For the one he loved, he wanted to hear those words first and foremost otherwise what he would be doing would have no meaning. For his first time, there needed to be a suitable atmosphere and a state of mind, and what better than the lustful wish of his Servant.

It began with a simple motion. The young man slid inside just like that, as if that hole was made for him. It welcomed his muscular shaft with ease. A low, guttural moan escaped from Musashi's lips as she felt him enter for the very first time.

He hit the half way point before sliding back out. The movement nearly sent the woman over the edge as she cried out. However, had she been content with simple love making, she would have said so. Her intentions were clear right from the start. She wanted to be fucked, to be used, to be utterly wasted. That was why the inexperienced Master was going to grant her wish. What he lacked in experience, he more than made up for with energy and lust as he pounded on the swordswoman's pussy with all his might. With every fiber of his being, he plunged deep into her sex and retreated, only to do it again and again until he settled on a rhythm which even Musashi's body quaked from the shocks.

She wanted to let out the sultriest voice she could muster, but Ritsuka didn't allow her. His lips devoured hers without delay, sending pleasant shivers all around her body. Her eyes fell backwards as fire and ferocity assaulted her refined samurai body from different angles. This was not something her training prepared her for. But she was not completely helpless either. Her hips gave enough fight to the pounding that they involuntarily moved to meet her lover's. Each time he thrust forward, she would meet him halfway with her own hips pushing upwards.

They made out and fucked liked animals under the guise of the hot spring's steam filled air as they declared, "I love you" to one another.

By the time Musashi reached her second orgasm, the woman rolled themselves until she was on top and Ritsuka sitting on the ground. Naturally, she didn't let her cum-filled hole let go of her Master's cock. It was entrancing watching the profound swordswoman pleasure herself by riding him with her legs spread wide, Ritsuka thought. She didn't spoke any words or commanded anything. She was barely even looking at him. Despite being drunk on sex, she still retained her beauty. The young man couldn't help but admire her perfect figure, her breasts which were not abnormally large yet not remotely small either, her smooth yet toned stomach, her wide, lustful hips, and her beautiful face free of any impurities, they were all so perfect, like artwork which had been perfected to the extreme. He watched as this beautiful woman pleasured herself on his cock. Her body simply moved on instinct as she sat herself up and forced her pussy up and down Ritsuka, all the while her voluptuous tits were bouncing. The young man knew better than to leave them unattended as he sucked and played with her womanly jewels. As she bounced up and down Ritsuka's cock with her hands on her knees for support, her ass and hips created smacking sounds as they hit the young man's body. It was impossible not to hear them from afar.

Eventually, Ritsuka neared his limit. He grunted and moaned, unable to endure the pleasure his Servant provided him. "Musashi… I'm about to come…."

It was unclear whether the swordswoman understood him at this point. He was surprised she had such repressed desires hidden inside her steely, battle hardened exterior. But she felt her tense up all the same.

"I love you, Ritsuka…" she managed to whisper finally. Albeit driven to lust, she still could not forget her own feelings.

That made the young man smile. With their sweat covered bodies so close, he couldn't help but embrace her. "Yeah, I love you too, Musashi. Let's reach the end together shall we?"

Their soft and gentle sides overpowered their animalism. The rhythmic beating of their hearts was in sync. The two sought no better chance to share a passionate kiss than now as they filled each other with warmth and love. True to his desire to fulfil her wish, he did end up filling her with cum, and she added her own to the mix.

By the time their elaborate lovemaking ended, the swordswoman passed out with a smile on her face. Perhaps it was because of the heat, Ritsuka wondered, but he smiled all the same and removed his still hardened cock from her.

It was quite the ordeal taking care of Musashi. He had to clean her up and dress her before returning her to her room. The dressing part was the hardest as he had no clue how to tie her yukata, and it was difficult restraining himself from taking advantage of her bare naked body. Still, he managed to make her look respectable, albeit the cloth was one tug away from falling apart, and laid her in her room to rest. His stiff wood never disappeared, but he was already happy that he and Musashi managed to experience something truly special.

He subdued all his desires for now as worry for his dear beloved overtook him. His place was right beside her. The look of satisfaction she gave made him smile, but still he knew that he need to take care of her. Kneeling by her side, he fanned her to cool her off, hoping that this would at least help in some way. Luckily for him, he found one of those circular fans just lying around. As he looked out for her, he wondered if he should go grab a glass of water just in case she wakes up.

It was at this moment that another person stepped inside the dimly lit room unannounced.

Ritsuka was too late to notice that another one of his Servants managed to close in on him.

It happened so suddenly. The young Master was pushed down, his back hitting the tatami mat. Someone dug inside his yukata and pulled out his stiff cock from its restraints. Despite not knowing who it was, and despite being close to his lover, the mouth which engulfed his cock felt incredibly good. It was warm and wet, not to mention hungry. It sucked him lovingly, moving up and down the thick shaft like there was no tomorrow.

When Ritsuka looked up, his face stiffened in horror. A pale maiden with skin as cold as ice, a hair so smooth and yet pale as if it had once been a perfect blonde, and soulless, yellow eyes which lacked emotion, went down on him devouring his cock as she would devour her food. Arturia Alter gave no regard to the cries of her Master as she serviced his shaft. She watched him tremble and moan from having her mouth kiss and suck him.

"What are you doing, Arturia? S-Stop that right now! Ohhh!" His mouth groaned as he saw the Alter ran her tongue across his cock with her emotionless eyes watching him intently. That movement sent his head swinging backwards with his mouth gaping wide. The cold sensation was completely unexpected, just the tip of her wet tongue tracing against his skin sent shivers across his body.

"I wouldn't make a sound if I were you," she whispered as she brought her pale hand out to rub him up and down. "We don't want to make that gaudy woman to wake up and find you with another Servant. Honestly, you two were so loud that I just happened to walk in and watch the entire thing."

"You saw all that?!" cried the young man in a low voice while still being jerked off by her smooth hand.

The swordswoman next to them still laid there completely motionless and exhausted. He breathed a sigh of relief as he heard her deep breaths, but his attention was pulled away immediately by the stroking of Arturia on his cock.

"Yes, I watched her become a total slut and give in to her desires so easily like a total pig I knew she was. It was almost laughable. But for a pig to be so worthless as to leave her own Master with a stiff wood like this, it's irredeemable," she said as she slowed down her strokes. Ritsuka's cock was completely hard and ready to go at this point. "If she can't at least finish her man, then I believe she is not worthy of you, Master. At least I will not allow you to leave without being unsatisfied no matter what."

"No, that can't be right," he whispered. "Stop this! Musashi and I are together already. You hear me? I love Musashi, and she loves me back. There's no room for you and your cock hungry attitude in our relationship, so get off of me and go back to your room."

He started to push her away, but she held her ground and went back to sucking his cock as if it was the most important thing right now. Ritsuka couldn't help but stifle his moans lest he wakes up her beloved Musashi. Said woman was still sounding asleep with her arms on either side of her shoulders. Her yukata had long since unravelled to reveal her plentiful breasts. The angle in which she leaned her head was facing him and Arturia. Should she open her eyes right now, she would find them closely entangled with each other.

Meanwhile, Arturia was sinking the young man's cock deeper in her throat. She was ravenous as usual, not letting go of her prize at any given moment. She was like a dragon, a greedy, voracious dragon that guarded her treasures closely. No one would steal from her, or she would unleash fire upon them, not even this loudmouth samurai sleeping dumbly in her futon instead of being sensitive to her own Master's needs. Ritsuka was helpless in her grasp. She would not allow him to deter her from finishing her mission. She did everything, from massaging his balls to taking him deepthroat. She played all the tricks up her sleeve in order to steal her Master back.

Her hard work soon paid off as she felt him tense up and shake. His knuckles turned white as he dug his nails on the floor. He gritted his teeth for the inevitable, and Arturia merely opened her mouth and stuck her tongue out to accept her prize.

Hot, sticky, white cum rained down on her face. It landed on her mouth, her nose, her hair, and her chin. She wasted no time and scooped up all the cum that landed on her before gulping it all down her mouth and moving towards the cock head which was still dribbling with his seed. Ritsuka held his head back, panting hard from climaxing.

"Amazing." Arturia's voice managed to draw his attention. She was still gripping the base of his member as she inspected it. "You're still hard. Even after taking two Servants, you're still this lively. My, my, it seems I picked the right Master to serve. It's a shame that pig won't be able to watch what I'll do next to you."

Ritsuka couldn't move nor voice an order to stop her. However, even if he could, there was no doubt she would continue nonetheless.

The evil queen stood on her knees now. Her ponytail swayed from side to side. She pulled her black sleeveless shirt off of her and threw it away before peeling her shorts. Japanese clothing didn't appeal to her, so she had chose to remain in her Shinjuku attire while the others changed.

The young man didn't want to admit it, but the Alter was a whole another level of her own. She didn't have the soft quality which Musashi possessed, but he could tell she had such a firm, lean body. Her breasts were smaller but perky. There was a different kind of appeal to them. Downward, the shapes of her muscle could be seen. Her stomach, though not obvious, was actually quite toned. It looked perfectly smooth. Her skin was a pristine white and bore no impurities. And finally, her stature was quite small. She looked almost as young as him while being an old monarch. Overall, Arturia Alter had a captivating beauty of her own, different from that of the buxom Musashi. She was sexy, plain and simple, he admitted. His animalistic instincts were in war with his conscience for thinking of such things. Even as his meat throbbed angrily in the sight of her ridiculously sex figure, the desire to explore, ravage, and most of all, fuck it were so strong, his inner self was still shouting at him to remain faithful to his one true love. But the struggle was undoubtedly real. Her temptations were slowly drilling inside his brain.

"See anything you like?" The Alter let out a foxy smile in her cool demeanor as she slid closer to Ritsuka until she was directly on top of him, his tool pointed at the ready even more now. Perhaps watching her nude helped. "Since she stole your first time, I will just have to steal another first from you as well. What about it, Master? I will only do this with you and only you. Of course, I will not allow you to object."

Before Ritsuka could even interject, she began moving abruptly. She lowered herself until her anus was directly touching his cock. It slid even further and missed its mark, but the length of his shaft rubbed against the middle of her cheeks, sending pleasant shivers across her spine. The feeling of his length against her was enough to get her hot and aroused. She bit her lip, feeling impatient, and raised herself up. One of her hands grabbed firmly onto the shaft as she lowered once again, guiding it directly into her backdoor.

The pain started to show itself once he entered her virgin asshole. It was a lot tougher than expected considering how much she lubed up his cock with her spit beforehand. She nearly screamed out loud, but the evil queen was not going down without a fight. Even with the exploding pain, she continued. She took the entire length as far as she could. Her eyes were shut tight, and her face was sweating profusely. It took a long moment before she could get accustomed to his girth. Her anal walls began to relax, and the long, desired moment came. "So gooooooood….." she stuck her slack tongue out as she relished her anus being penetrated. Her perky butt lifted itself up and fell down, and she shivered. "So gooood… It's so goooood!" Before long, she was setting the pace and fucking Ritsuka using her butthole. Up and down she went on his length with her back arched outward and her hands on his thighs for support. She felt so full with his cock inside her. The evil queen enjoyed herself like a whore. All traces of her cool, emotionless act were gone at this point. She was no longer the great Arturia Pendragon, wielder of the sacred sword Excalibur, but merely a starving slut wanting her holes filled with thick cock, her Master's cock specifically.

Ritsuka, more than ever, felt his emotions tested while under the influence of the Alter. Her reign upon him would not stop until she got what she wanted and fucked him to get ahead of his lover. He would be lying if he said he didn't enjoy the incredible sensation of her asshole. Even now, he was still holding himself back from going any further in this. He just loved Musashi that much. The special bond they shared was important to him, and he wanted it to remain exclusive to her alone.

His arms and legs steadily regained their strength. His eyes flashed with frustration. Perhaps it was the energy of the moment or his own anger at his special memory being deprived by this wretch, or both, but Ritsuka could not hold it in any longer. He violently pushed the Alter back while she was enjoying fucking herself with his cock. A dull thud resounded in the room.

"So you'd rather satisfy yourself with your dirty hole, huh, you slut?!" He shouted, completely forgetting that his partner was just right beside him. Everything else seemed to disappear as he let his rage to set in. After all he was deprived of something very important, something he shared with that beautiful swordswoman. His memory of this evening was stained by this depraved intruder, and he would not allow this to go unpunished. "Then I'll use you until you are broken. Now, spread your legs, slut, after all, that's the only thing you are good for."

It was like a beast had possessed Ritsuka. The way he moved his hips and pushed his entire girth inside her was ruthless and free of affection. He didn't made love to her like she did with Musashi, it was more like practicing his limit on a disposable doll. He did not care for her even as he raised her legs up and slid his tongue across her beautiful feet. She fucked her without remorse. The sounds of slapping flesh echoed as he held her leg up high in the air like a support beam and thrusted his hips forward, pushing the lithe body of the Saber on the ground. With her legs spread at this ridiculous angle, she couldn't even react at all. Her bare shaven pussy and unimpressive breasts were laid bare to her Master. The strength she had was drained when the young man took the initiative from her.

"Ahh! That's it, Master! Harder!" Arturia, however, seemed to enjoy it. "Harder! Fuck me like I'm a lifeless filth! Treat me like a plaything. Conquer me like the conqueror you are!" The loudness of her shrills cries should be more than enough to disturb all the guests around them, let alone the motionless swordswoman just within arm's reach. They fucked in her presence and mouthed out all their grunts and moans without a care. The pounding of flesh upon flesh, hips upon ass, easily filled the room with noise.

He did not let go of his grip on her leg for even just a second, but he did not feel that this would suffice as a punishment. With one swift motion, he reached out and took her rock hard nipple in his hand. She let out even more moans of pleasure as he began roughly teasing it and pulling it hard. The Alter was losing her mind. Her exposed tongue let out drools which spilled onto the floor. Her pale, yellow eyes were distantly rolled upward as she shook.

Ritsuka was getting tired of watching her delusional face, so she flipped her over and raise her ass up so he could take her from behind. He could not help but admire that king's ass. One could say it was the ass of Britain. The young man gulped and reached out with both hands to fondle her cheeks.

Arturia let out a silent groan while smiling. "... Do you like my ass, Master? If I may, people call my ass quite desirable." Her cheeks were flushed as she glanced behind her, meeting his gaze. Her face showed an expression of desire and seduction. The simple movement of his hands on her cheek made her roll her hips a little and sway her ass temptingly. "I would even go as far as to say that it's my best asset. What do you think, Master?"

The young man wouldn't allow himself to show the tension he felt to appear on his face, for if he did, it would be the same as admitting that she was right all along and that she won his feelings over the samurai. Thus, he his face was stone cold. Even as he replied, his voice contained a hint of sarcasm. "Yeah... It's a wonderful ass." He squeezed her perky cheek a few times, memorizing the softness of the feeling and eliciting a moan from her. "It's not as wonderful as Musashi's though, but it will do."

The Alter smiled, knowing that he wasn't being entirely honest. Her efforts to tempt him still continued with her moving her ass to his rubbing. "So even with such a great ass in front of you, you still feel nothing?"

The Master furrowed his brows, trying to not show how hooked he was in her seduction. He could not allow Arturia to know how horny she made him. "Yeah... it's not the first ass I ever seen. Musashi's is much better and much more plump. You're more like a ragdoll, but... I'd give you points for having a decent ass."

"Mmm..." Arturia let out a sultry moan. Her eyelids were half closed as she gazed at him with a look akin to a venomous snake to a mouse. "If that woman is so much better, then why did she leave you hanging like that? Why didn't she satisfy you to the end?"

"She did satisfy me! She made me the happiest man alive!" His anger began to boil again as he shouted out. A small movement could be seen from the corner of his eye, but neither one of them noticed it. "She just passed out from the heat is all! Even Servants have their limits! I can't blame her for that! I'm not some monster who pushes people aside when they can't meet expectations. If she were to say she was unwell and can't go on, then of course I would stop midway to allow her rest. Her health is much more important than my sexual desires obviously!"

"You know, Master." The pale, naked evil ruler of Britain let out a satisfied grin. "If I were in her place, I wouldn't tell you to stop. If it was me you were fucking in that hot spring, I wouldn't pass out. My desire to have sex with you, to have you make me your slave to your every whim, far supasses some trivial thing like heat."

"Wha..." Ritsuka's mouth dropped like a log as images of Arturia taking Musashi's place manifested in his mind. All manner of speech left him. The poison which she slipped through his ears were words that seduced his very sexual appetite.

"And even if I were to be taken out of action from the sweltering heat, I wouldn't let go. I wouldn't allow you, the owner of my soul, to leave without making sure you were satisfied." Her eyes were different now. Gone away was the tempting witch, and in its place was a woman longing for her desired partner. "With my lifeless body, I would service you until the sun rose up from the horizon. I would readily give you clearance to do as you wish with my limp body. Master, that's how determined I am to prove myself to you."

"Arturia..." It was clear that his mind was a mess at this point. His mouth flapped open and closed. Their surroundings blurred. His gaze became limited to only Arturia's subservient body, which raised its butt, glistening with sex, higher up to show how much she wanted it.

"With all my soul, I vow to make you pick me, not that loud pig, but me, Arturia Pendragon. Choose me, Master, and I promise to be better than her. I won't let you experience such lonely nights. Now, take me. Please, I want it so bad." As if she couldn't take it any longer, her ass grinded against his raging meat which had been standing there dazed.

Even without his consent, Arturia began to moan and pleasure herself as she grinded against him. The slick sound of their loins rubbing against each other could be heard.

Ritsuka, however, shook his head and could not accept it. "No, this is wrong!"

"What's so wrong about it? What can't you understand?!" She shouted in between moans. Her voice sounded desperate and frustrated, as if reaching the end of an argument but not quite.

"Even if you say, even if you swear, I can't let you take her place no matter what!"

"Just give in to your desires, Master! Don't think, just take me. This is what Miyamoto Musashi should be doing at this point. But it's not her here, it's me! I'm the one who is comforting you in this lonely darkness, not her. Why can't you accept it already?!"

"Shut up!" Ritsuka couldn't take it anymore and plunged into her ass in order to cut off her words. The Alter let out one of the most perverted noises he had ever head. "Shut up already! I can't stand you pleading. If this makes you stop your delusional logic, then so be it!"

Arturia began noisily moaning and encouraging him to fuck her harder, but the young man simply slapped her pale, perky butt, leaving a clear red mark of his hand print on her soft, left cheek. "Shut up, you damn wench. No one wants a king who is loud and uncouth. If you want me to fuck you so much, then learn some manners."

"I'm sorry... I'm sorryyyyy, Master! I just can't help it! It's too good!" She covered her mouth with her hand, but even that was not enough to stop her from voicing out her innermost thoughts. She had to bite her own fingers, swallow them in, in order to muffle herself.

He slapped her ass one more time on the same spot. It sounded like a whip crackling with a sharp noise upon hitting her soft flesh. At this point, Arturia covered her own mouth with her hand as she tried to stifle her moans, some of which came from his cock ramming her, but most of it came from the angry slaps themselves. Ritsuka was uncaring. Even after Arturia silenced herself, he didn't let up on his enforcing his punishment on her, not that Arturia wanted she minded, in fact she was begging for him to do so. Her skinny body laid face down against the floor with only her ass up.

She came after only a few minutes of him thrusting his cock in her ass. A considerable amount of cum spilled from her narrow slit and soiled the tatami mats. Despite that, Ritsuka had no desire to cease fucking her. He would not stop until he completely broke her. The spanking had already reached both of her cheeks. Their once pale surface was now overcome with scarlet red, almost as if blood would draw from them any second.

Ritsuka had used her ass through three of her orgasms. He had pulled on her ponytail hard, cupped up and spanked her ass, while doing so without stopping, and even with that, she still seemed to have enjoyed it. He decided to finish where it all started but baring in mind that his cock had been in her ass this entire time.

Sprawled on the ground, twitching with a great helping of cum running down from her unused slit, Arturia's state of mind was almost indiscernible as her eyes were blankly looking up with her mouth agape.

"So this is what the king of sluts truly looks like," commented the young man without a tinge of emotion. "Get up and do your duty, your Highness. But… On second thought, stay like that. I'll do it myself."

His thumb touched her bottom lip and pressed on it, pushing her mouth open until he deemed it wide enough. He pointed his stiffness downward and descended her opening until he reached her throat. He raised his hips and slammed it down once his cock nearly left her mouth. He fucked her like that without even looking down to check her satisfied expression. But he could feel her gag and gasp for air each time he descended. The time he stayed like that grew longer and longer until the Alter couldn't take it any longer. Soon, he began raping her mouth once again until he finally came, shoving it all deep in her throat.

He sighed as he finished. He didn't want to leave anything behind, so he dumped everything inside that servant's mouth. She had long since passed out, sprawled naked with cum leaking from her pussy and mouth.

How did it end up like this? He sighed yet again and picked the girl up in his arms. She was awfully light, unlike Musashi. But the way he, still thoroughly pissed at what she had done, just dumped her in her room along with her clothes was so completely blunt compared to his gentle treatment of her beloved samurai.

He went back to grab some water for him and Musashi before cleaning up and finally retiring for the night.

I realized that I forgot to write an author's note on my first edit, so here it is.

This a two chapter story. I originally wanted to post this thing whole, but my schedule made it inconvenient.

The first chapter is setting Musashi and Ritsuka's relationship, and Arturia intervening.

The next chapter will have Jeanne in the mix, explaining what her standpoint in this love... quadrangle(?) is. I'm considering adding a dash of yuri and some kind of dom/sub theme for part two, but we'll see.
