The air in the shed was thick with the musky scent of sex, the Aphrodite Grail's pulsing light casting a dim, rosy glow over the writhing bodies. Rin Tohsaka leaned against the rough shed wall, her body trembling, thick streams of milky cum dripping from her lips and down her chin. Her glazed eyes barely registered the night sky through the grimy windowpane.
WHAM!
Shunsuke's arm snaked around her throat from behind, tightening just enough to make her breath hitch, forcing out desperate, strangled moans. His sweat-slicked abs slammed against her bare ass, his monstrous cock buried deep inside her, withdrawing almost completely before ramming back in. Each brutal thrust sent more cum—thick, hot, and heavy—splashing down her inner thighs, pooling on the dusty floor beneath them.
"Fuck, Rin, you're still so tight," Shunsuke growled, his voice raw with lust as he gripped her hips, yanking her back to meet his punishing rhythm. "You love this, don't you? Taking every inch of me."
Rin's mind screamed in protest, but her body betrayed her. "N-no… I… oh, God!" she gasped, her voice breaking as another wave of pleasure crashed through her. What the hell happened to me? Her original resolve was crystal clear: stop Ai Yoshizawa, claim the Aphrodite Grail, fight a Grail War if necessary. She was prepared for that. But this? This raw, depraved ritual of relentless fucking? It was beyond comprehension.
His lips found hers, wrenching her head sideways for a messy, hungry kiss. His tongue plundered her mouth, tasting the mingled cum and spit as he pounded into her. "Your pussy's gripping me so fucking hard.," he rasped against her lips, his hands clamping her waist like vices, pulling her harder onto his cock. Rin's hips rocked back instinctively, craving the friction, the searing heat of his thick shaft grinding against her sensitive walls. The pleasure was mind-numbing, consuming, drowning out every shred of her rationality. The Aphrodite Grail floated silently above, its dim light pulsing with every thrust, as if feeding on their depravity.
SLAP!
"Fuck!" Rin cried out, her body shuddering as another scalding load shot deep inside her, filling her womb. Her knees buckled, her pussy clenching around him as a desperate, glistening spray erupted from her clit, soaking her thighs. "No… more… I can't…" she whimpered, but Shunsuke was already hardening again, his hips resuming their brutal pace.
"You can, and you will," he growled, his voice thick with dominance. "This is what the Grail wants." He slapped her ass, the sharp sting sending another jolt of pleasure through her. Rin's consciousness blurred, her body surrendering completely to the relentless pounding. She was nothing but a vessel for his lust, her pale flesh quivering with each impact, cum streaking her thighs and face—remnants of when he'd painted Luvia's body earlier.
Luvia was no better off. She clung to Shunsuke's side, her lips seeking his in a desperate, sloppy kiss. "More… give me more," she begged, her voice trembling as she ground her dripping pussy against his thigh. Ai Yoshizawa knelt between his legs, her tongue diligently lapping at his balls, moaning softly as she savored the taste. "So good…" Ai murmured, her eyes glazed with lust as she sucked one into her mouth, her fingers working her own clit.
"They're all insane… we're all insane…" Rin thought, a twisted sense of freedom washing over her. Fuck it. She twisted her hips deliberately, hooking an arm around Shunsuke's neck and pulling him into a deep, wet kiss. "Fuck me harder," she whispered against his lips, her voice dripping with need. Splurch splurch splurch. Her belly made obscene sounds with every thrust, her pussy overflowing with his cum. She'd lost count of how many times he'd filled her, filled them.
Through the window, Rin's hyper-attuned ears caught voices. Two girls, archery club members, had stopped nearby, their bow bags slung over their shoulders. One was Sakura Matou—her biological sister, adopted by the Matou family. Rin's heart clenched as their conversation drifted through the thin wall.
"Matou-san, you always practice so late! Is it for the upcoming competition?"
"I just… want to use the time to improve myself. To catch up to the person I admire~"
"Oooh, scandalous! Don't tell me you have a crush on a boy~?"
"Eh?! W-well, it's a bit embarrassing to say… the person I admire… is actually Rin Tohsaka-senpai from the second year…"
"Ohh! You mean the Tohsaka-senpai? The really popular one?"
"Yes! She gets top grades, she's got perfect conduct, she carries herself with such elegance… Besides me, lots of people at school admire her."
Hearing Sakura's confession, Rin's face flushed an even deeper shade of crimson. No… don't say anymore… Unghh—! The sweet, gentle Sakura had no idea that as she spoke, the very senpai she idolized was being fucked raw in the shed nearby, Shunsuke's hands clamped on her hips, lifting her slightly as he slammed into her rear entrance, shooting another thick load deep inside that made her toes curl and her whole frame shudder uncontrollably. After only a moment's gasp for air, the brutal pounding resumed…
"She's right up there with Luvia-senpai, after all~~ Speaking of Luvia-senpai, when she transferred in, I was totally blown away! So elegant, so knowledgeable, beautiful like a doll, and her figure is incredible~" Like Sakura, this girl had no clue that the Luvia she admired was currently coated in sweat and cum, cradled in the boy's arms while he groped her massive breasts, their mouths locked in a sloppy kiss as he simultaneously finger-fucked her pussy from below.
"So, to follow the people we admire, let's both work hard! Though you really don't have to stay this late with me every time~"
"No, no, it's fine! After all, Matou-san, you're someone I look up to too! It motivates me to practice together~" Suddenly, the girl remembered something, pointing to a nearby bench. "Feels like ages since we just chatted like this. Want to sit and rest for a bit?"
And so, the two girls sat down on the bench, just three meters from the shed, continuing their earnest talk about Rin-senpai and Luvia-senpai. Neither knew that just meters away, behind them, Sakura's precious Rin-senpai was now being held against the window, eyes rolled back white, as the boy drove into her from behind, lifting her feet clear off the floor with the force of his thrusts, fucking her into a shuddering, minutes-long climax that left her knees weak and unable to support her...
As Sakura chatted with her friend, covering her mouth in a light giggle, her eyes drifted idly toward the shed behind her. Abruptly, she saw thick, white spatters hitting the windowpane in rhythmic spurts. What was that? But just as she tried to focus, her friend drew her attention back, and she dismissed it as seeing things.
For Shunsuke Miyano, it was a debauched, phantasmal orgy of the flesh. Completely inexperienced before this, he hadn't just climbed the staircase to adulthood; he'd fucking pole-vaulted into a sexual abyss. He lost track of how many bodies were writhing in the darkness, whose slick flesh he gripped, whose wet mouth was clamped onto his cock. All he knew was the overwhelming command of his own primal lust, the siren call of 'Aphrodite' guiding him. He fucked like a man possessed, burning through his life force, rutting endlessly with the women surrounding him until oblivion finally claimed him.
***
When Shunsuke woke up, he was lying in a luxuriously furnished, European-style room. He was wrapped in an unfamiliar bathrobe. Three girls sat nearby, watching him. Outside the window, stars dotted the sky around a high, bright moon. Inside, flickering candlelight from a three-pronged candelabrum cast dancing yellow light on the girls' faces. Like him, they were also clad in bathrobes. Now, finally, Shunsuke could clearly see who they were.
Raven hair tied into pigtails cascading over her shoulders, striking blue eyes like sapphires watching him with a complex, troubled expression. Her pretty face, with perfectly shaped cherry lips pressed thin, was familiar yet terrifyingly distant. Her balanced figure was draped in the robe, hiding the curves he now intimately knew. Her famously beautiful legs, usually encased in black stockings at school, were bare now, sleek and white, devastatingly alluring. This was Rin Tohsaka, the super-popular girl from Homurahara Academy he wouldn't normally even dare greet.
Beside Rin, instantly recognizable by her elaborate blonde drill curls tied with blue ribbons, sat the other school goddess. Her refined features held a touch of aristocratic pride. Her bathrobe, trimmed in blue and gold, strained dramatically over a bust even more generous than Rin's, creating an almost exaggerated curve. Her voluptuous figure seemed incredibly mature for a high schooler. This was the renowned transfer student and Finnish heiress, Luviagelita Edelfelt.
Sitting next to them was a girl Shunsuke didn't immediately recognize but pieced together. Her skin tone was slightly deeper than the other two porcelain beauties. Her dyed blonde, short hair gave her the vibe of a 'troublesome girl' that honest guys should avoid. Her legs were leanly muscled, straight and powerful, suggesting athletic prowess. It took him a few seconds, but he placed her: the rising star of Homurahara's track and field club, the second-year Ai Yoshizawa, famous for her talent, looks, and seemingly endless circle of friends—a popular girl to the core.
"Shunsuke Miyano. Sole heir of the Miyano magus family," Rin began, picking up a piece of paper and glancing at it as he stirred. "Records haven't been updated by the Clock Tower for two generations. Which means, like the Yoshizawa family, you fall into the 'fallen family' category." She looked at him directly. "How's your body?"
"...My body?" Shunsuke didn't know how to answer. Physically… sore? Drained?
"If it weren't for my jewel pendant providing healing," Rin muttered, more complaining than explaining, "you'd be crippled, if not dead. Do you even remember how many times you came? Talking about that, obviously. Honestly…"
Despite Rin's exasperated, blushing tone, Shunsuke felt a strange calm descend. At least she'd bothered to heal him. Things couldn't be that catastrophic.
"In any case, Miyano-kun," Luvia interjected, casually flipping one of her golden drills and crossing her legs elegantly, adopting an air of command. "Do you understand the current situation?"
Shunsuke thought hard, trying to piece together the nightmare. "You… were fighting over a treasure called… the 'Aphro… dite Grail'? Then… you started a ritual, and I got caught up in it—is that right?"
"Broadly correct. Allowing you to eavesdrop certainly saved us some explanatory effort," Luvia nodded, her proud demeanor a stark contrast to Shunsuke's vivid memory of her whimpering and grinding against him like an animal begging for release. "However, you weren't simply 'caught up'. You were 'chosen' by the Grail. Distinguish the difference."
"I was… 'chosen'?"
"A product of the Aphrodite Grail's inherent 'malice'," Ai Yoshizawa explained breezily, as if discussing common knowledge. "The ritual for this 'war' is intrinsically linked to sex. Meaning, if you were some irredeemable scumbag, you might have been spared. Unfortunately for you, you seem like a decent guy. Therefore, it wants you dead. So it 'chose' you."
"Wants me dead?" Shunsuke fell silent, instantly grasping her meaning. "What a malicious magical artifact."
"Regrettably, the morality of power lies with the user. Aphrodite embodies wickedness, yet it is immensely powerful—altering phenomena, granting wealth and power, an omnipotent wish-granter forged from the world's evils. Since its excavation from that Greek temple, this is the closest it's ever come to completion," Luvia's voice lowered, hardening with determination. "Unfortunately for it, I despise losing. Especially losing to this woman," she shot Rin a look. "So I will absolutely not relinquish this Grail."
"For a magus, it represents the only path to grasp Truth, to rewrite destiny," Rin stated, not explicitly stating her own desire but her eyes burned with resolve.
"Reviving a fallen family might be a trifle for the Grail. But for someone like me, lacking innate talent, seizing this single chance requires betting everything," Ai looked directly at Shunsuke. "Sorry for dragging you into this. Although we formed a… rather special physical bond tonight, I won't show any mercy going forward."
"But…" Shunsuke scratched his head, posing a logical question. "If I have zero interest in the Grail, can I just… quit?"
"The Grail accepts only one form of withdrawal: defeat," Ai stated plainly. "However, the specific rules for 'defeat' in this copulation-based conflict haven't been fully established yet. So, if you wish to withdraw now," her eyes held a chilling emptiness, "you'd likely have to choose the most… common form of defeat."
"Such as?" Shunsuke asked, dread coiling in his stomach.
"Defeat resulting in death," Luvia declared, her sapphire eyes devoid of pity as she stared at him. "Shall I assist you with that right now?"
Faced with this absolutely unacceptable condition, despair washed over Shunsuke. After a long, heavy silence, he clenched his jaw, sat up straighter on the sofa, and met the gazes of the three beautiful girls before him. "Alright then. Can you tell me the specific rules?"
"As its temporary custodian, I can only outline the basics," Ai conceded. She then began explaining the rules of what she termed the 'Copulation War'. In essence: use any means necessary during sex to force your opponent(s) to climax repeatedly, driving them to dehydration, exhaustion, or even deep unconsciousness. Doing so created a probability of triggering a 'defeat judgment' from the Grail itself.
Furthermore, to 'assist' the girls in their struggle, the Aphrodite Grail had utilized—Ai paused, glancing at Shunsuke with unnerving neutrality—a portion of Shunsuke's cum to create seven sets of 'Ritual Implements'. As Rin, blushing furiously and glaring daggers at Shunsuke, materialized a glowing, amber-hued, vaguely rod-shaped object in her hand, the sheer absurdity and perversion of the Aphrodite Grail hit Shunsuke anew.
The object solidified into a milky-white, wand-like thing. Its surface held faint, swirling textures, and it possessed a certain… warm luster. However, both ends… both ends terminated in shapes that were embarrassingly, undeniably familiar to Shunsuke. No wonder Rin looked utterly mortified.
"What… is that?" he stammered.
"It's a common type of… sexual aid," Ai explained, her tone impossible to read. "A 'Ritual Implement' crafted by the Grail from your… essence. It also utilizes your shape and size—quite substantial, isn't it?"
Shunsuke could only stare, dumbfounded by Ai's nonchalant delivery. In contrast, the three girls seemed disturbingly quick to adapt.
"Hmph…" The haughty Luvia actually offered Shunsuke a grudgingly positive assessment, though her cheeks were slightly pink. "Well. That's about the only commendable trait you possess, creature."
"Let me reiterate!" Rin burst out, face flaming red but spine straight. "This is WAR! Everything I did was a necessary SACRIFICE! I would NEVER voluntarily engage in copulation with this brutish woman using this… this implement! I was FORCED!" Even now, red-faced and flustered, Rin felt compelled to reaffirm her rivalry with Luvia, who immediately fired back.
"Heh heh. Thank you for clarifying on my behalf, Tohsaka. My sentiments exactly," Luvia sneered.
"Furthermore," Ai cut through their bickering, continuing her explanation to Shunsuke, "each participant will be assigned a Servant, summoned by the Grail, to act as an assistant. They will share in the Grail's power upon victory. Remember, in this Copulation War, only they cannot and will not betray you."
"So… where are they now?" Shunsuke asked, bewildered by this new layer of madness.
"In other rooms of this mansion. You'll meet yours soon enough," Luvia dismissed Rin and fixed her gaze on Shunsuke. "In conclusion: this is the first, and the last, time we will sit together chatting like civilized people at a tea party. The next time we meet, we are enemies." Her tone and the cold fire in her eyes left Shunsuke with no doubt: Luvia would kill him without hesitation to win the Grail.
"Okay… one last question…" Shunsuke swallowed hard, gesturing vaguely at himself and then the three girls. "Last Night… exactly who… did I have sex with?"
Luvia delicately hid her face behind an imaginary fan, her ample chest rising and falling rapidly as she visibly suppressed… something. Rin hugged herself tightly, looking utterly furious and ashamed. Ai merely stared back at him with those empty eyes, delivering the final, devastating blow.
"All seven of us. Including the Servants you haven't met yet. Did you… enjoy yourself?"
Seeing Rin's humiliated rage and Luvia averting her gaze, chest heaving with barely controlled fury, Shunsuke's mind flashed back to the slick, writhing chaos in the shed. He vividly recalled Rin's frantic cries of 'No… no more… please…' as he'd shot load after load into her, her body completely losing control.
