Corruption of Fate
By: Elf
Despite the chill of cavern, sweat was slowly trickling down Tohsaka Rin’s neck, throat, face and back. In a pocket in her skirt she had her eight remaining ten strongest gems and in her hand she had the AZOTH dagger. Saliva trailed down her throat as her heart pounded loudly in her chest. The heartbeat was deafening in the silent cave, so loud that someone would hear the intruder inside.
Rin was alone. First the Shadow had taken Saber, then a corrupted, dark version of the tiny Servant had appeared and drug Shirou off with her. The Shadow had appeared and Archer was absorbed trying to protect her and the Eizenbern heir. Both magi had managed to escape to Kotomine Church only to have the church later attacked by Sakura. Ilya had been killed in the attack, Kotomine had managed to fell an Assassin class servant that somehow Matou Zouken had managed to summon.
During the battle she had found out that Kotomine had been keeping a Servant alive from the past war. Normally, she would have been furious at his treachery, but this Servant just happened to be the oldest and most powerful Heroic Spirit of all time, the King of Urrk, Gilgamesh. Golden, beautiful and arrogant to match his insane power, Gilgamesh was the only reason Rin hadn’t been killed, or worse, taken. He’d already been furious with this Shadow eating “his” subjects and he was not going to let Sakura win.
Not to mention he’d been furious to find out that Sakura had absorbed Saber and made the blond her own. The king had stomped around, snarled insults about mongrel whores and that Saber was his and his alone. Intrigued by the fact that Rin was determined to stop her sister at any cost he volunteered to become her Servant. So once again Rin was Master of an arrogant Archer class Servant.
Except he’s not my Archer, she thought sadly. Archer’s face flashed through her mind, the sad smile on his face as he caressed her hair before staggering up to his feet to face the Shadow, Dark Saber and the Assassin. He told her to take Ilya and run. Despite all of his teasing at the beginning, he sacrificed himself without a second thought. She desperately wished that she would have known who he had been and known him longer.
If I had a wish, I would wish you back, she thought to her fallen Archer. However there would be no wishes. Both Gilgamesh and Kotomine had been very specific about that. Apparently the Grail was full of corruption due to the Eizenbern’s folly of the Third War. It was full of all of the World’s Evil, Angra Mainyu, and if released it would coat the world in all of its malicious intent. So that was why Rin was in the cave to stop her sister at any cost while Gilgamesh would fight Dark Saber.
She could feel him burning mana through her remaining Command Seal and knew he was still doing well. There was no flicker of him weakening as he continued to fight. So she would find Sakura and do what she had to do. Strengthening her resolve, Rin continued deeper in the cave.
A flash of burning pain filled her wrist and she winched at the familiar feeling. She turned her hand over and looked at her wrist in horror as the last Command Seal faded to a pale bruise on her skin. The shock of mana hit her in the chest as her eyes widened. A soft, feminine giggle echoed through the now large opening of the cavern around her.
Rin froze as an all too familiar voice said, “Hello, nee-san.”
Standing there was a figure eerily beautiful with white hair, fair skin with deep red markings like intricate vines curving up her throat, cheek and hands. A dress of mana as dark as India ink with lines of deep crimson clung to ample curves and the skirt was silted to reveal supple legs with the same alien red pattern tattooed on pale skin. Eyes like the giant ruby in the AZOTH dagger locked with Rin’s as the being formerly known as Matou Sakura smiled. Rin’s chest tightened at the familiar pink ribbon still tying part of Sakura’s white hair back but she swallowed and gripped the dagger even harder in her hand.
“Sakura,” Rin replied as she stared her sister in the eye.
Sakura rested one hand over her heart and the other over her stomach. The frightening smile was still etched on her pretty features as she said, “So, did you come to stop me, Nee-san? Did you come with that new Servant thinking you could?”
“That was part of the plan,” Rin replied as she saw huge shadowy shapes starting to form through the corner of her eyes.
Sakura shook her head and said, “I didn’t know what he was, but . . . his mana is easing some of the ache. Thank you for bringing him.”
Rin gritted her teeth and asked, “So, are you going to use him against me now too, like Saber?”
“Oh no. I didn’t like him, so he was just devoured, and anyway, this should be between us anyway, right Nee-san? Aren’t you going to tell me how wrong I am?” Sakura asked as her eyes closed and her smile broadened.
Rin said nothing and dug her pale blue topaz from her skirt. She shook her head and shouted to release the spell in the gem. The pale blue gem went flying towards the girl in black, ice already starting to spread to its intended target. Shadows wavered in front of Sakura and grew, rippling into a vaguely humanoid shape that seemed to reach the top of the cavern. In a mighty sweep, it swatted the gem away as if it was nothing as Sakura giggled.
“Like I said before Nee-san, I’m stronger.”
******
“Oh no, Nee-san, it’s no fun unless you’re awake.”
Something soft, warm and wet pushed against Rin’s lips and granted entrance. Rin’s eyes flew open as she realized Sakura was in front of her with her lips planted against hers. Raven tresses swung fiercely as Rin tried to shake herself free of the near bruising pressure. Fingers with a steely vice like grip captured the girl’s chin and held her immobile as lips, teeth and tongue ravaged her untried mouth.
Rin automatically tried to move, to throw her attacker off of her, but she cried out as she found her arms and legs bound. Her hands were above her head and her legs were spread apart, forcing her almost completely immobile. Sakura pulled away with a giggle as she reached out with one finger to touch Rin’s swollen lips.
With a smile, the younger sibling asked, “Was that your first kiss, Nee-san?”
Shame washed over Rin as if someone had doused her in napalm. A bright flush rivaling the red sweater spread over pale skin as aquamarine eyes gleamed angrily. Sakura smiled at the reaction, giggled and rubbed Rin’s lip with her index finger. “I think it was. Did you enjoy it?”
White teeth worried into the swollen lip as no answered was uttered and aquamarine eyes continued to glare. Sakura smiled even more and said, “The school idol, rejecting all of the boys had her first kiss stolen by her unwanted sister. How does that make you feel, Nee-san?”
Rin didn’t answer as her cheeks continued to burn. Her heart was pounding at her vulnerability as she was bound immobile by the shadowy tendrils of mana that her sister could call at will. She had long ago exhausted her supply of gems, the AZOTH dagger and her own supply of mana shooting gandr as a last attempt to keep this from happening. When it counts, I always mess up.
“Does it make you feel dirty? That no one will want you because you’re soiled?” Sakura asked as she raised the finger that she had just used to caress Rin’s lips to her own. Rin’s eyes narrowed at the girl and Sakura leaned forward, soft white hair brushing against her cheeks as her nose touched hers. The crimson eyes were soul shattering, the gaze filled with so much anger, pain, hate and malice.
Sakura said, “You don’t know what it’s like to feel dirty, but you will. I’m going to soil you Nee-san, like how Grandfather did to me. I’m going to turn you into a shameful girl, Nee-san, a receptacle for others’ pleasure. And eventually, you’ll start to crave it, you’ll need it.”
Tiny shivers like ice cubes raced up and down Rin’s spine as her stomach clinched. Her heartbeat echoed like a drum in her ears, thundering so fast she thought it was going to burst from her chest. She swallowed as she looked Sakura in the eye and said, “You’re pathetic. You should have been stronger. Instead you broke just like Zouken wanted you to.”
Sakura glared at her and those red laced hands moved to Rin’s breasts. Streaks of fiery agony rushed through the girl’s body as those nimble and deceivably strong fingers clamped through two layers of cloth to pinch and twist vulnerable nipples. Rin arched back with a cry as her sister continued her assault. Sakura let her go with a shake of her head and said, “That’s pathetic Nee-san.”
Deep, shuddering breaths filled Rin’s lungs as she worked through the pain. Hot tears streaked down flushed cheeks unbidden. Crimson eyes lit up as white hair again touched flushed skin and a tiny tongue lapped up the salty, near scalding droplets. “Delicious,” the other girl whispered before backing up.
Sakura’s crimson eyes traveled over Rin’s slimmer, more athletic form thoughtfully before she brought up one finger. A slim tendril of darkness edged in deep crimson whirled languidly before straightening and cracking right to the white cross stitched against the familiar red sweater. Fabric gave way, splitting to the mana’s onslaught as it was brought down again and again, shredding the red turtleneck and black skirt to ribbons. The white lace and black satin ribbon camisole was next, leaving Rin in nothing but white panties and her thigh highs. Sakura dropped to her knees and gingerly pulled off Rin’s loafers, casting them to the side.
Rin looked ahead at the dark cavern stretching around them and did not look at Sakura. The cool air of the cavern caused already aching nipples to harden to tiny points and raised flesh in tiny goose pimples. The sweat that had accumulated earlier during the fight was almost whisked dry, leaving skin shivering from response to the chill. Rin shivered and she heard Sakura laugh, causing her cheeks to burn even more.
“You know Nee-san, I rather like you like this,” Sakura said as she rose languidly to her bare feet, “Now I just need to figure out what to do with you.”
Rin swallowed hard, resisting the urge to shut her eyes and to scream or beg. Pale hands reached up to cup small, firm breasts. “They’re rather small, aren’t they? But they’re cute like that, Nee-san,” Sakura said with a teasing giggle as her thumb delicately brushed against the hardened points.
Her breath quickened as sensation sparked through her body as she shut her eyes. “Sensitive, Nee-san?” Sakura’s breathy voice whispered as her warm breath caressed a heated ear. A hot, wet tongue caressing a delicate curve of an ear caused eyes to snap open and a deep breath caused the helpless body to tremble.
“S-stop it,” Rin whispered as she shook her head to get away from her captor.
Sakura pulled away with a smile and asked, “It’s not very nice to have your body crave something you don’t want is it?”
Rin glared and snapped, “If you didn’t fight it, then it’s your own fault.”
“Oh, is it really, Nee-san?” Sakura said as a scowl marred her pretty face. A pale hand rose up and a snap echoed through the cavern as slim fingers rubbed together. The shadows shifted and jerked hard, keeping legs spread but bending at the waist as hands were held together and back. Rin’s eyes widened as she was bent forward with her legs spread, even more vulnerable than before with her rear up in the air.
Sakura smiled and asked, “So, is this your fault then?”
“No, I fought,” Rin snapped back only to have Sakura vanish in a wavering of darkness. Raven tresses swung as the girl’s slender neck turned as much as it could to look back. In the corner of her eye, Rin could see Sakura standing behind her with a smile as she grabbed the white cotton acting as the only shield on her body.
The sound of delicate fabric tearing was almost deafening as the white scraps were discarded easily. Rin felt her cheeks flame even more as she was bare to her sister and swallowed down the lump forming in her throat. Her heartbeat was thundering in her ears as Sakura ran her index finger over her delicate cleft. She shut her eyes and bit her lip, turning her head away from the sight.
Cool air caressed bare skin, but did nothing to chill the shame staining pale skin. That slow finger kept caressing the gentle slit in a feather light touch, but nothing else was happening. The finger was removed and Rin felt her body relax ever so slightly in relief. She took a slow breath to calm herself when something spread her open to the air, exposing her most inner self. Her eyes flew open and she turned her head to see Sakura studying her thoughtfully before holding up one finger with a wicked curve of her lips.
Rin’s eyes widened as that one finger prodded at the dry hollow of her body. Then Sakura drew her hand back and thrust forward sharply. Rin arched back with a scream at the painful, burning invader within her. Her inner walls worked to try to push the intruder out, but there was no avail. Tears burned her eyes as Sakura said, “So tight, Nee-san. You screamed, did it really hurt that bad?”
Tears threatening to spill from her eyes, but Rin said nothing. “And it’s just a finger in you, Nee-san. Imagine how much it’s going to hurt when something four times as big enters you like this.”
Teeth were gritted as Sakura continued, “I can’t make you feel what Grandfather put me through, but you’ll get a better understanding. If I just hurt you like this it’ll make me worse than him, and I’m not. I’m going to soil you, Nee-san, but I’m going to make you beg for it.”
The finger twisted inside the tight, dry channel giving forth another unbidden cry. Rin tried to rock her hips to help ease the burning pain, but it did little to relieve her pain. “Archer-san, I have something for you,” Sakura called out in a sing song voice.
Rin’s eyes widened as the darkness parted and a familiar figure stepped out. Her heart caught in her chest as she stared for endless moments at the figure garbed in red and black standing before her. Steel grey eyes widened as she met them. She wanted to sob in relief, call for his aid, have him make all of this go away and just collapse into his brawny arms.
“Archer,” she whispered, her voice not quite a plea as she looked at her Archer.
******
The firm curve of a toned backside, spread beautifully sculpted legs framed by black stockings revealing luscious, thighs and the innocent pink core framed by soft folds was enough to bring any man to his knees. Despite his best intentions, Archer’s eyes traveled to his current “Master’s” index finger plundering what should be his. Tear filled aquamarine eyes met his as her hoarse voice whispered to him.
He took a step towards her and Sakura slowly withdrew her finger from her sister’s dry core. The blackened mana clad girl slowly swayed over to him, the trails of her makeshift dress lightly touching the cavern floor. The finger that had been violating his Rin was held up to his face and his nostrils flared at the spicy scent there. His whole body stood at attention as he looked at Rin spread and humiliated, ready to be ravaged and used.
“Hmph, so you do want Nee-san,” Sakura said with a scowl and a snort as her eyes went down to the heavily strained leather of his pants. “You really are a broken Sempai.”
Archer folded his arms over his chest and replied, “And yet you keep me around, even though I’m not your †˜Sempai’.”
She turned so her back was towards him and then leaned back, the finger that was in Rin resting on his lips. He took a deep breath as her soft, lush backside rested against his body as she looked up at him. “Well, I have my Sempai who wants only me, and it’s only fitting to have the one person that Nee-san could trust break her, right?” she said with a smile.
“Rin’s not going to break,” Archer said as Sakura brushed her finger against his lip. It tasted slightly bitter, tangy, with a slight salty edge to it, but it was Rin. Sakura trailed that hand down his throat, over his cuirass and down to the ridge trying to escape its leather confines. Her hot hand pressed against the hard length and fire shot through his veins and licked up his spine throughout his body.
Her lithe hand continued to stroke him through the leather as she said, “You’re going to break her with this Archer-san. It’s so thick and long, do you think it would fit in her?”
Aquamarine eyes sparked possessively and fingernails bit into palms as they were watched. Archer knew exactly who’s Archer he was, despite who was currently his sham of a Master right now. Just he had to play the balance between pacifying Sakura and protecting Rin’s sanity. If Sakura had her way, she’d just unzip him and have him thrust into Rin as she was now and violate her until she broke.
Rin was strong, but she had limits that Archer was all too aware of. However, he couldn’t deny that he wanted Rin and his eyes met hers as her sister continued to stroke him until it was agony. “Well, I’ll need to work on her,” Archer replied in a low voice as he resisted the urge to thrust his hips into Sakura’s hand.
Sakura rested her head on his shoulder and looked up at him with those freakish crimson eyes. Her hand squeezed, applying enough pressure to make him buck and groan in response, his eyes fluttering shut. “In her mouth first, Archer-san,” she whispered to him as she let him go to work on the fastenings on his armor.
He watched as Rin’s eyes widened and her mouth clamped shut. He swallowed and asked, “What?”
Sakura continued to undress him, letting the armor hit the ground with a hard thud. He watched as Rin’s eyes flashed as she watched them, her cheeks reddening even more as her body arched with a deep breath. His own eyes widened at that before a slow smile spread across his features as he realized how he could please the younger sister and protect the elder. Sakura unlatched the fly on his leathers and began to slowly pull them down his hips. His length sprang free and he watched as Rin’s eyes widened before they clinched shut and she looked away.
“Sempai is not going to become like you,” Sakura whispered to him as her fingers skated over the many scars over his body, “He’s going to stay with me.”
Archer wanted to trace something and kill the girl before him. Saber was in no position to protect her due to her fight with Gilgamesh. If Sakura hadn’t called upon him the King of Knights would have been defeated, but Archer had a feeling that it was becoming a game between the two mad Servants. However, Sakura didn’t have his loyalty like she had Saber’s. While his body was coursing with corrupt mana, he still had his full range of sanity and sense of self, just a sickening need that was raging through him. The hard, thick length was throbbing painfully since the Servant had been “taken” by the Shadow with no release, not even one granted by his own hands.
It was made even worse since Dark Saber had managed to capture Emiya Shirou and bring him back as well. Until Sakura finally broke due to her Grandfather and Shinji, she’d been protecting his younger self and the two of them had constantly, and awkwardly on the boy’s part, been making love to hold her need at bay. Not that was particularly arousing, but due to the link with Sakura both he and Saber were getting the backlash of her need. However, unlike Saber, he had been paired with a Master at the beginning that always drove him crazy with want.
He shook himself as Sakura guided him over towards Rin. His chest tightened at the sight of her bound and humiliated, and knew that Sakura was just getting started. Through the link with her, he knew what she’d been through and how she was now unreasonably blaming Rin for everything. He was also very aware that she wanted to put Rin through the same humiliation and torture that she had.
And he’d be damned again if he’d stand by and let Sakura do that to Rin after she’d killed Ilya.
Archer reached out and stroked her hair just as he had before he’d been taken, noting the flash of anger in crimson eyes. Aquamarine eyes opened and looked up at him, and for a moment it was just the two of them. The fear melted from Rin’s beautiful features as he continued to stroke her thick, soft raven hair. Before Sakura could do or say anything, he bent forward and lightly pressed her lips against hers.
He stayed like that for an endless moment as he felt Rin’s breath quicken against his lips and her mouth part awkwardly against his. Moments later the two of them were tasting the other, moving lips, teeth and tongues in perfect synch. Archer pulled away as they were both gasping for air and darkened aquamarine eyes met his. Hands like steel gripped broad shoulders as the Servant was jerked back up to his feet, his engorged length even with Rin’s swollen lips.
Sakura shoved him, causing the thick head to press against Rin’s lips. Rin’s eyes widened and flickered at the sight of the thick, pulsing length in front of her and Archer couldn’t blame her fear. Rin clamped her mouth tightly shut and turned her head to the side. Archer stiffened as her thick hair caressed his length and spiked his need even more. “Now, now Nee-san, if you can satisfy him with your mouth, maybe he won’t stick it in you,” Sakura said with a chuckle.
“Go to hell,” Rin said between grit teeth.
Archer inwardly flinched as Sakura’s eyes flashed again and more shadows appeared. They jerked Rin’s head back into place and then Sakura moved over to her mouth. She held Rin’s nose shut with one hand as the other pulled on her chin. After long moments of struggle, her mouth was open.
However, Archer stayed completely still unless he was forced to do this as she was. Shadows pressed against him and he was shoved forward. Swollen, hardened length passed between soft lips until Rin started to gag. He moved to pull out, but the shadows were holding him in place as well. “If you relax Nee-san, you won’t choke,” Sakura said sagely with a nod, “Now, be good and make Archer-san come.”
His heart was racing and his whole body was thrumming with need. He was surrounded by wet heat and softness that cradled him unwillingly. Hands clinched into tight fists as an unmovable will resisted the urge to thrust. Rin made no move around him and Archer’s eyes widened as one tendril was poised threateningly over Rin’s vulnerable core. To his horror, it poked Rin and the girl’s eyes shifted to look.
“If you don’t Nee-san I’ll use this. Now choose, Archer-san or this,” Sakura said with a smile.
Aquamarine eyes looked up as grey eyes pleaded silently in return. Trust me, Rin, Archer thought to her silently, hoping that she’d understand him. He reached out and stroked her hair again and those gorgeous eyes narrowed and flashed with the fire he adored that just sent more heat through his body. Sakura leaned forward and added, “And unlike Archer-san, I can push this into your womb. Won’t that feel nice?”
Silken lips began to softly move over his throbbing length and Archer’s breath was drawn out of his body in a rush. A soft, hot tongue flickered over him clumsily as Rin’s mouth worked over him. She began to suckle, trying to find a rhythm, but it was still enough to almost put him on his knees. He gripped her hair with a groan as her tongue found the thick vein that caused stars to dance behind his eyes and shot fire through his core.
“Oh, look, Archer-san’s enjoying himself,” Sakura said with a grin as Rin flicked her tongue over that vein again. “He’s going to fuck you Nee-san. My Servant is going to take your virginity, how does that make you feel?”
Aquamarine eyes shot fire as Rin continued her task, her cheeks turning even redder. Archer was breathing hard as he felt himself starting to swell even more. His hips were moving on their own accord as all he became aware of was Rin’s mouth on his swollen need. It felt as if molten steel was flowing through his veins and pooling at his center, threatening to shatter him from within. Sakura leaned towards him and added needed pressure at the base of his length, spiking everything even more.
“You want to feel her blood on you, don’t you Archer-san?” she whispered in his ear as his body began to tremble. “Feel how big he is Nee-san? He can’t even fit all into your mouth. Can he fit inside of you?”
Archer felt himself shatter with a low cry as his body bucked hard. His length swelled even more, causing Rin’s eyes to widen and a low choke reverberated through his system. He attempted to pull himself away, but Sakura pushed him fast as he pulsed and throbbed. White hot release pulsed through him as he empted himself between Rin’s lips in hot spurts until his body gave out.
******
Rin nearly choked at the hot, thick, salty and bitter fluid that filled her mouth as Archer’s huge member spilled into her. He had tried to pull out, but Sakura and her shadows had pushed him until he was spent. He slid from her lips and staggered, breathing hard as his body was covered with a slight sheen of sweat.
She moved to spit out the thick, disgusting substance out. As the glistening, pearly white liquid spilled from abused lips, a white hand with twisting red vines reached out to catch it in their palm. Rin’s eyes widened as Sakura lifted her hand up and gave a low whistle. “So much, Archer-san . . .” she said in her breathy voice.
Eyes like molten steel met Rin’s and she steeled herself, knowing that he was as unwilling as she was. However, her eyes were drawn to the thick muscles of his body, his broad shoulders, narrow hips and long legs. They etched over every scar that had been pounded into his body over his life time. Her Servant, her hero, her Archer. Hers.
His eyes were infinitely sad and apologetic as they looked at each other. There was something else there as well, a deep need that had made her shiver despite herself. His eyes looked pleadingly at her again and she nodded ever so slightly. They would make it out of this together and somehow get her sister back.
“Watching that got me excited,” Sakura said in a low voice as she parted and lifted her mana dress to reveal her smooth slit. Even in the dim light of the cavern, Rin could make out the wetness coating her thighs dripping from the weeping slit. Sakura took a deep breath as she parted herself with two fingers to reveal dripping folds. She then proceeded to slather all of Archer’s spent essence over her core.
Rin felt a possessive surge well up inside of her as she glared at her sister coating herself with Rin’s Archer’s essence. Sakura smiled at her and said, “Since you enjoyed the taste of my Servant so much, I’d figure that you’d be more inclined to clean him off of me, Nee-san.”
Red lined legs took another step towards Rin until those gleaming folds were right at her mouth. The salty, bitter, musky smell mingled with the tangy and musky smell of feminine lust so heavily that it could be tasted. Eyes darted around for a sign of tawny muscles, white hair and grey eyes. In the corner of her eye, Rin saw Archer slowly kneel down behind her, his eyes locked on Sakura’s.
A smirk played across his handsome face as he asked, “Master, may I show Rin how to do this?”
Crimson eyes narrowed as Sakura glared at her Servant. She replied, “Archer-san, what are you doing? I didn’t order you to go back there. If I didn’t know any better, you were wanting to do this to Nee-san.”
“She’s barely wet, Master, and I know that’s not from your ministrations. As she is, I don’t think I’ll be able to perform adequately, and I’m already spent . . . I might not be able to repeat the process without proper . . . stimulation,” Archer said as he made no move to rise to his feet, if anything, his face was inches from Rin’s vulnerable center.
Rin’s heart started to pick up and she arched slightly to escape her Archer’s keen gaze upon her. She took a deep breath as she felt her core clinch ever so slightly as she looked back at him. He gave her the barest of nods and she blinked once in return before turning back to Sakura. She smiled at her sister and blew on her ever so slightly, causing pale thighs to quiver ever so slightly as Sakura drew a quick breath.
A rush of power overcame the bound girl at the minute sign of weakness as she moved forward. Bracing herself, Rin’s tongue flickered out unsurely across the slick folds. She tasted the thick saltiness from Archer and moved to lick that clean, working her tongue into scalding heat. Sakura arched back and small hands intertwined into thick hair as Rin worked. Her stomach fluttered in protest against the bitter saltiness sweeping back into her throat, but she was rewarded by Sakura’s tiny gaps.
Then, suddenly a broad tongue licked Rin from the entrance of her body to the small nub at her apex. Her stomach fluttered, tightened and her core began to weep as heat swept over her body. Fire lit along nerves as the talented tongue swept around the tiny center of need, causing it to harden and swell with want. Rin’s cheeks were burning with something other than shame that lit all of the nerves of her body as she was suddenly aware of what felt like lust pouring through her body.
Taking that as her cue, Rin darted her tongue through the trembling pink hollow, tasting thick, bitter musk that seemed to pour on her tongue. An unsure but kitten like tongue darted over swollen folds to a tiny nub peeking out of its apex. She swirled her tongue around it faster than the slow, delightful pace Archer was teasing her with and was rewarded with Sakura crying out.
Lightning cackled along her spine as she felt soft, sucking pressure of that point of need that caused her to arch and cry out into her sister’s wetness. Pressure was building up more and more, threatening to explode cataclysmically. Lungs were working over and over again at a rapid rate to draw more air in as the fire swept over untrained nerves in a way that was threatening to shatter them into nothing. Shoulders slumped as a heart thundered uncontrollably due to Archer’s talented tongue and lips.
Fingers dug into the soft flesh of hard thighs to remind Rin what her task was. She wrapped her lips around that nub and sucked as hard and fast as she could. She scowled as she realized that nub was starting to retreat into its soft folds so she sucked even harder, flicking her tongue out to tease it as well. Pressure was welling up inside of her, but Sakura bucked forward first with a cry.
Hot lust poured out of the corrupted girl and flowed onto Rin’s face right as the tension sprang. Rin felt her vision flash black as her whole body seized with a scream. She screamed as she felt her empty core clinch nothing in rhythms that matched her heartbeat before it left her spent and trembling. The exhausted body slumped forward in its bondage as it gulped for air.
As she continued to breathe as her heartbeat slowed from the soul shattering experience, a soft, trembling hand stroked her cheek. “You did a very good job, Nee-san,” Sakura said in a hoarse voice.
She was blurred in Rin’s vision as her core gave a delightful shudder of an aftershock as Archer placed a soft kiss on her quivering flesh. Rin swallowed and nodded, still too shattered to properly answer. She did see Sakura look back behind her and ask, “Well, Archer-san?”
Something pleasantly thick and long slid inside of Rin, causing her to arch at the fullness. She rocked towards it ever so slightly as her body clinched it needily. She gasped at the feeling, so different than the sharp, burning of Sakura shoving her finger inside of her. Then it began to move slowly back and forth, in and not quite fully out of her, stirring her up from within. The slightest caress brushed against the tingling center of need at the apex of soft folds, causing it to fire more sparks on sensitive nerves.
A moan escaped Rin’s lips as the slow caress built her up again, sending flutters through her stomach. Her core clinched needily at the length inside of her and she rocked her hips to feel more. Her half open eyes caught Sakura looking at her as a hand reached out to stroke her hair. Then the length curved up and rubbed something that caused an odd sort of tension within her.
Rin’s eyes flew open as she felt the sudden urge to urinate as the friction on her apex was increased. The rubbing inside of her continued as the shadows shifted from her knees to back to being upright with her legs spread and her arms above her head. She heard a familiar voice whisper, “Trace on.”
Her eyes widened at the full length mirror that appeared in front of her as she stared at the image there. Archer was behind her with one of his long index finger working inside of her while his thumb teased the tiny nub. Hard, tawny masculine flesh was against soft, lean, fair femininity and white hair against raven dark, a study of contrasts. Rin gasped at the sight of the rosy flush staining her skin, her nipples standing at hard points and her weeping core begging for Archer’s touch. She could feel his hardness poking her bottom and she bit her lip as the pressure within her began to build and build at a frightening rate as he continued to rub that spot hidden within.
Sakura moved to strum those hardened nipples with her delicate hands and Rin arched at the wellspring of pleasure that it brought. Silken hair caressed a sensitive ear as lips leaned forward close enough to kiss it. “Now, watch Nee-san,” a hoarse voice whispered as those clever fingers continued to rub the sensitive points over and over again, sending more tension through her body as she was going to explode.
A cry escaped from Rin’s lips as she began to tremble from the sheer force of what was overtaking her. One of Sakura’s hands moved from her nipples, down her body to her core right above Archer’s hand. Rin shook her head in protest of Archer removing his thumb from her as she hung on the cusp, the pressure overwhelming her. Delicate white fingers ran over the nub as it began to retreat back within. Archer’s finger pressed more inside of her as the nub was pinched and rubbed between Sakura’s thumb and forefinger.
With a deafening scream, Rin shattered again. She arched and bucked hard as she literally saw her own passion pour from herself and soak Sakura and Archer’s hands even more. Her vision flashed white as she shuddered and clutched Archer’s finger inside of her. The untrained body writhed hard as it trembled in ecstasy, writhing and writhing again as more screams filled the cave.
The white hot pleasure started to verge to something overwhelming and too much and Rin tried to move away. She felt tears sting her eyes as she cried out again only to have Archer bend towards her and capture her lips with her own. She desperately kissed him in return, trying to meet his lips and tongue as the best as she could as her nerves stopped firing. She was breathing hard against Archer’s lips and he stroked her hair back. She watched as he reached up to gently untie her hair from its ribbons with one hand, letting it spill freely.
The nimble finger retreated from the still quivering sheath, leaving it empty and a hollow hunger gnawing from within. Rin made a little mewling whimper of protest as she looked up at Archer. Sakura whispered in her ear, “Look Nee-san, you’re soaked. Do you want it that badly?”
Rin lifted her eyes to the mirror to see her thigh highs soaked with her own liquid need and the white skin above them gleaming with still flowing lust. Sakura reached down to gently separate the soaked slit to reveal engorged folds literally weeping with lust. “Such a naughty girl, Nee-san,” she chuckled as she began to use her index and middle fingers to stroke around the swollen apex.
A cry tore itself again from Rin’s lips as the hyper sensitive flesh was teased again. Her core greedily flexed in need as Archer lifted her up by her thighs. “Keep watching Nee-san,” Sakura all but sang out to her.
Aquamarine eyes widened in the mirror as tawny hands lifted the slim and blushing raven haired girl up to reveal a hardened, engorged length with the swollen head poking where Archer’s finger just had been. She tried to buck away from her former Servant’s grasp, but he was holding her like steal. A white head bent over hers in the mirror and a tongue lapped at her ear. Sakura’s soaked fingers moved faster, barely adding any pressure, but the speed and friction making her body tense even more.
“I’m with you, Rin,” the familiar rusty voice even rougher than normal whispered in her ear.
She met that steel grey gaze and he kissed her, the silent communication was all they were limited to due to Sakura’s interference. However that hot mouth slanted gently over hers was enough to get her to relax. She whispered against his lips, “I wanted you back.”
Then her body arched as she rocked on the edge, the tension built to its apex. One more twist of nimble fingers sent the tension rocketing over the edge. The intensity of this release wasn’t enough to make her scream as her body clinched and shuddered in response. She felt something impossibly thick and hard prod at her, separating her and felt as if it was burning her.
“Watch Nee-san. Not everyone gets to watch as they’re made into a woman,” Sakura whispered as she traced her finger around the still quivering nub at the top of Rin’s folds.
Rin opened her eyes to see Archer’s body tense behind hers, every coppery muscle in full definition as his white hair was falling into his face, making him look oddly familiar. His hair softened his features, making him look vulnerable and even more attractive. She swallowed down the burning pressure trying to break within her as she looked down to see the thick head of his length opening her up while Sakura’s finger still continued to tease. Sakura’s crimson eyes sparked as she whispered, “It’s big, isn’t it Nee-san, and he’s not even in you yet. It hurts, doesn’t it?”
Teeth were gritted as the burning and tearing grew worse and Sakura’s laughter echoed through the cave. She said, “Archer-san, you’ll never get in her like that. Here’s what you do.”
The shadows holding Rin shifted and suddenly she was pulled down hard
right on top of that hard length. She cried out as she felt something inside of her tear as it felt as if someone had shoved a hot poker inside of her. She felt something burning slide down her aching hollow and it wasn’t lust. Tears burned her eyes as she choked back a sob and she heard heavy breathing behind her as the one of the hands of her thighs let go to wrap around her waist, pulling her against overwhelming warmth. The scent of steel, leather and forge smoke filled her nostrils and Rin looked at the mirror again.
Archer was fully sheathed inside of her to the hilt, his own body trembling in response. Trails of bright crimson stained white skin, his swollen kneed as well as his thighs. Rin took a shuddering breath and concentrated, working through the burning invader that felt as if it was ripping her in half. Sakura’s fingers gently slid over the blood and she held it up to her own lips, stating, “So much Nee-san. I bled more though, but then again, I was younger.”
“I’m sorry,” Rin whispered in a hoarse voice she didn’t recognize.
Sakura eyed her as she languidly licked the red staining her slim fingers. She
snorted and said, “Well, you’re sorry now, Nee-san, with Archer’s cock buried inside of you.”
Rin bit her lip but didn’t argue as the pain started to subside ever so slowly. Instead she said, “Sakura, being a magus is not easy. It’s hard and it hurts, but I did want you to be happy . . .”
“Well, I don’t want you to be happy Nee-san,” Sakura said with a glare, “I see
how you and Archer-san are looking at each other, but he’s not yours and you’re not his. You’re both mine and I’m letting you do this because it amuses me.”
Archer nuzzled the back of Rin’s neck and said in his rough voice, “And what would Emiya Shirou think of you doing this to Rin?”
“Shut up, Archer-san. You’re broken, you’re not Sempai. All you are is something to hurt Nee-san,” Sakura snapped as she took a step back from them.
Archer kissed the side of Rin’s throat that sent little flutters through her again and
she sighed. He licked up the length of the white column and laved at Rin’s ear, causing her to arch prettily and flex her aching core around him. He whispered, “You’re like a vice, Rin.”
Her cheeks heated up at that as Sakura’s crimson eyes narrowed in anger. Archer smirked and continued, “So tight it’s almost painful. I might just be your plaything Master but you’d never get me this hard and wound up, not even if you used a Command Seal.”
Rin bit her lip and rocked her hips, feeling that thick length move within her, causing her to moan. Soreness rocked through her core, but she could handle this now and his answering groan and involuntary thrust of his hips made her burn even more. Tension was starting to build slowly, but even more deeply as he seemed to be hitting that same place inside of her that his finger skillfully touched moments ago. She leaned towards him and pressed her lips against his, tasting herself on his tongue even now as he responded in kind.
Within moments it was only the two of them and that was all that mattered. With
each powerful thrust of his hips and thighs, Rin rocked to meet him. Soon they were moving with perfect synchronicity with one and another, the pain of lost innocence just helping to stroke the flames within her. Tension was spiraling higher and higher within her again, each stroke that opened her up more and more to her lover that sent lightning through every nerve of her body. Tiny cries for her Archer escaped her lips as she repeated that he was hers over and over again as her name was heavy on his lips against her ear.
Soon the fiery tension was too much and it was crumbling resistance with ease. Rin was trembling as she felt the beginning of something huge welling up more and more within her until she could barely breathe and her body was trembling violently involuntarily. She cried out as she felt Archer get even bigger inside of her, her body forcing itself to accommodate his length and girth as he filled her, pressing into her until he couldn’t anymore. It felt almost as if that he was pushing against her womb, seeking his own completion.
With a loud groan of her name, Rin felt her Archer shudder and liquid heat rush through her. The sublime sensation sent her over the edge as she screamed, her body rippling with intensity as her vision flashed black then white. She rocked against him and her body squeezed him greedily, milking every ounce of his essence into her. Hands like steel held her close as she quivered against and around her until she fell forward.
Or would have fell forward if it wasn’t for the bindings holding her in place. She was breathing hard and felt strong arms hold her close as she felt Archer’s generous length start to dwindle inside of her. He was breathing hard and his muscles were trembling, but he made no move to let his precious cargo go. Rin wanted to touch him in return, hold him like he was holding her but they were both captives. She opened her eyes to look at Sakura who was chuckling ever so slightly.
Archer slid out of her and Rin shifted as she felt a sickening crawling within her. Sakura wordlessly pointed at the mirror with a smile as she leaned forward, her fingers tracing over Rin’s still quivering core. Rin’s eyes widened at the blood smeared on her as well as her own lust. However her breath caught as she saw the generous amount of thick, pearly fluid streaked with red trail from her wide open core. Sakura’s index and middle finger circled around the opening with a giggle. “So much, Archer-san. You completely filled Nee-san up,” Sakura said, “Well, how does it feel to be filled with a man’s come, Nee-san? To have it drip out of you like this? To be soiled?”
Rin looked into her sister’s eyes and said, “You should have chosen someone who wasn’t mine, Sakura.”
The ring finger joined the first two and then thrust inside of Rin. Rin bucked up with a cry at the abuse to her sore hollow. “Still tight too, Nee-san, but that’ll change, and then Archer-san won’t want you anymore, but I will,” Sakura said with a smile before removing her fingers, “Enjoy your Archer-san while you can, but you don’t have long.” With that she vanished, the shadows holding Rin following suit.
The two of them held each other, figuring out what their next move was. Rin’s mind flew around in circles, but she had no idea what to do. Archer whispered to her, “Are you up to saving your sister and the world?”
“Are you?” Rin asked with a wan sigh.
His smirk was the same arrogant one that made her want to slap him when they met, instead it made her smile. He replied, “Of course, let’s do this.”
Then, together former Master and Servant proceeded to save a sister and an alternate version of one’s self as well as the world.
