Summary: Rin winds up with Ishtar controlling her body after a botched ritual. She’s been running wild, and has now propositioned Shirou with his girlfriend’s body, and bet: if he can outdo her in bed, she’ll let Rin have control and do as Rin and Shirou want. As a goddess of love, Ishtar is confident, but Shirou has an ace in the hole; the butthole, that is. Ishtar doesn’t know about Rin’s defenseless anus, and by the time she finds out, she’ll be begging him to fuck it.
-x-X-x-
“Hmph. You really are persistent, aren’t you?”
Even thought she says it in Rin’s voice, even though she says it with Rin’s lips… Shirou knows even before she turns around and gives him an imperious grin that this is not Rin. While Rin could certainly be rather egotistical, and sometimes insufferably smug, hers and Ishtar’s personalities were still different. Not quite night and day… but easily apples to oranges.
Still, while it might not be Rin talking to him right now, she was still using Rin’s body. And Shirou couldn’t let that continue. Gritting his teeth, the young man holds his swords in white-knuckled grips as he stares down his enemy.
“So long as you insist on using my friend’s body without her permission, I’ll have to be.”
Ishtar releases a tinkling laugh at that, something that Rin would be mortified at if she heard it come from her mouth. Stepping away from the balcony she’s stood at, the goddess possessing one of his girlfriends enters the hotel room he’s invaded, a smirk stretched across her face.
“And what… the blonde one isn’t here?”
Shirou’s teeth grind all the more at the mention of Saber. He and Artoria had split up, hoping to cover more ground. They’d had a number of leads on where Ishtar might have taken Rin’s body, and not nearly enough people to cover all of them. In the end, they’d had to go their separate ways. Shirou had simply been lucky enough to find Ishtar before Saber. Lucky… or perhaps unlucky. Because now he was all alone against what was essentially a pseudo-Servant, and he couldn’t say for sure whether he could win or not, even with his Reality Marble as a trump card.
Stopping only a few feet away, Ishtar rakes the eyes of her unwilling host up and down, her smirk only widening further as he frowns.
“You summoned me, you know. What did you expect to happen? I needed a body, and this one has proven quite suitable for my needs.”
Shirou growls.
“It was an accident. You weren’t… the ritual was interfered with. You’re not supposed to be here. You’re not supposed to be in Rin’s body.”
Ishtar laughs again, and Shirou is almost ready to attack then and there. But at least she’s not trying to flee yet, and maybe, the longer he can keep her talking, the more chance Saber will have to reach them. Shirou wasn’t stupid after all, he’d still sent a message to her as soon as he confirmed Ishtar’s presence. But he couldn’t afford to wait for her to arrive. Now though, now he just needed to stall.
“But I am. And now it’s my body. Unless…”
Shirou latches onto that like a lifeline.
“Unless what?”
If there’s a way they can get Ishtar to back down willingly, he’ll gladly take it. Of course, it still feels like he’s hooked himself on bait, rather than anything positive, especially when Ishtar’s smile turns positively evil.
“Do you know what I’m the Goddess of, human? Beauty, of course. Good Harvests, because the people should love me. War, because the people should fear me. And of course, Lust and Fertility, because the people should think of me in their happiest moments. But, I’m also the Goddess of Discord. What do you think that means?”
He doesn’t know. Ishtar giggles again, and steps forward. She brings up a hand and runs it down the front of Shirou’s chest, causing him to swallow thickly at having Rin’s body touch him in such a way.
“Let’s play a game, you and I. We’ll have a wager, alright? A simple bet, and if you win, I’ll give back control to the original owner of this form. But if I win, you become my willing servant. I find myself in need of some quality help now that I exist in this mortal form.”
Shirou scowls, but he doesn’t dismiss the idea out of hand. It might be his only chance, after all.
“What’s the game?”
Ishtar’s grin is that of the cat who caught the canary as she leans in ever closer, until her lips are an inch away from his, her eyes, Rin’s eyes gazing up into his own.
“I want you to fuck me, human. If you can out-do me in bed, if you can defeat me in sex, in a battle of lust and desire, then I will submit to both you, and the one who even now rattles fruitlessly in her cage within me. What do you say?”
Shirou’s mouth is dry as he processes what she’s said. But then, there’s a thought. And as that thought crystalizes, he finds himself dismissing his armaments back to nothing, straightening up as he looks down at the goddess before him. He understands what she’s playing at, what she’s planning. But he has a chance, even if she no doubt believes she already has him beat.
“I say… I say yes.”
The eyes, his girlfriend’s eyes, light up at that, and Ishtar happily closes the rest of the difference between them, immediately dragging Shirou down for a kiss. The young man’s hands slide instinctively down her sides, and when she walks him back towards the bed behind him, he allows her to do so, until he’s sitting and she’s crawling into his lap, kneeling on either side of his body.
They continue to makeout, and Shirou can immediately see that this goddess is very good at what she does. Her tongue swirls around his, and he can barely keep up with her as Ishtar grinds her barely-covered mound down onto his bulge. He groans into her mouth, his fingers digging into her sides. Into Rin’s sides. Shirou knows Rin’s body quite well by this point. He and she and Saber have been making their three-way relationship work for quite some time.
But this is something completely new. Ishtar doesn’t use her body in the same way Rin does. She has more experience, possibly even an eternity of it. It might as well be an eternity, in the face of Shirou’s own burgeoning sexuality. As she moves her hands down his front and begins working at the front of his pants, Shirou grunts again into her lips. Trying to keep up, the red head aims to strip her as well… but then, Ishtar is already half-naked. The white and gold get up that she’s clothed Rin’s body in is almost certainly not Tohsaka’s style… but Shirou would be lying if he tried to claim it isn’t attractive.
Still, even if there’s nothing underneath, Shirou pushes aside the goddess’ dress, he grips and squeezes and kneads in all the right places. And Ishtar even reacts somewhat like Rin would, she groans and arches her back and undulates into his touch. But it doesn’t stop her. It doesn’t fizzle her out like it sometimes did with Rin. With Rin, if Shirou or Saber touched in the right places, they could turn her to putty in their hands.
With Ishtar, she only went partial putty, and she never gave an inch in the form of control, even as he squeezed at her sides, before moving his hands to grip her ass cheeks. Instead, Ishtar pushes him back onto the bed, and pulls his cock free from its restricting confines. Shirou grunts as Ishtar disengages from his lips to grin down at him, all while stroking his cock up and down quite eagerly.
“Ooh, now this is a beautiful specimen. To think, I ran away from this? I’m never letting you go, human.”
A moment later, and she’s lifting herself up to sink down on his length. His cockhead presses against her pussy lips, as it has many times before, and then he’s slowly being enveloped by her, by Rin’s tight, warm insides. Ishtar clearly feels it all, moaning as Shirou stretches her human body out… but it’s still not enough.
In no time at all, the goddess is bouncing up and down on Shirou’s cock, moaning happily, but still in complete control of the situation. And Shirou can’t deny that it feels good, he’s already groaning, panting beneath her as he struggles to keep himself under control. If he can’t even hold his release back, how the hell is he supposed to turn the tables on her?
Still, he does have one last card to play. It’s akin to his combat trump card, in a way. A secret he knows about Rin, one that she’d kill him if he ever told anyone else. Not even… Not even Saber knew about this particular weakness. To be fair, Shirou had found it out by accident. Completely by accident. It wasn’t like he’d done some adventurous exploring or anything like that, much to Rin’s chagrin and reluctant enjoyment.
Regardless, knowing he’s on the ropes, knowing he needs to turn things around, Shirou goes for the kill while Ishtar is clearly at the height of her confidence, completely and utterly sure of her victory. Shirou’s hands, still on her pert posterior as she bounces up and down on his cock, dig in a bit deeper, his fingers sliding into her ass crack. And then, before she can realize what he’s doing or react in any way, Shirou thrusts his index finger right up her ass.
Ishtar’s back goes ramrod straight, just as it did when Rin was in control and he did this exact same maneuver. Unlike Rin, Ishtar’s reaction is slightly more subdued. Her eyes wide and her mouth open in a small o, she slowly looks down at him, honest confusion coloring her gaze.
“What… w-what are you doing?”
It might not have been the instant climax he got out of Rin, but Shirou isn’t ready to give up. Staring Ishtar right in the eye, Shirou slides his digit in and out of her ass. At the same time, he begins to thrust upwards from below, as Ishtar has completely frozen in her gyrations atop his cock. The small o of her mouth turns into a bigger O, and Shirou ups his game, pushing the middle finger into her ass right after the index finger.
That’s when Ishtar finally reacts somewhat like Rin did.
“What are you doooiiiiiing!!!”
Her eyes roll back in her head, and she half-collapses onto Shirou’s chest as she convulses and spasms from the sudden orgasm. But he’s not about to stop there, and he continues to finger her ass faster and harder, loosening it up as he fucks her from below all the while. Ishtar tries again and again to recover, looking up at him with a face that contorts in unwanted and unexpected pleasure.
“Y-You… you…”
Shirou just maintains eye contact and continues to fingerbang the tight goddess’ asshole, even as she shakes and shivers, shuddering again and again from his ministrations. And then he cums, because even with the upper hand, he can’t hold back forever. But that’s okay, because Shirou is halfway there already, he can practically see the finish line. Despite feeling him cum inside her, Ishtar is far from triumphant. She tries, but she fails to even manage a smile as Shirou pulls her off of his cock, and then summons a Noble Phantasm with one effect and one effect only.
“H-How dare you!!!”
Ishtar snarls as he uses the ‘sword’ to tie up her hands. It honestly didn’t deserve the title of sword in his personal opinion, but it had been one of the weapons that Gilgamesh had thrown at him. A sword that’s pommel unwrapped into endless rope under the mental control of it’s wielder. Shirou easily restrains Ishtar’s wrists over her head, even as he spins her over onto her front, lifting her hips up towards him with his free hand.
His cockhead bumps against one of her ass cheeks, and the pseudo-Servant looks back with wide eyes as she suddenly realizes what he’s about to do.
“W-Wait!”
Shirou doesn’t even hesitate. He can’t afford to let Ishtar get any semblance of control back, he can’t afford to let her so much as re-assert herself if he’s to win this little game. So, without mercy, without pause, Shirou forces his lubed-up cock into Ishtar’s ass, into Rin’s ass. It’s the first time he’s ever fucked Rin’s ass, as a matter of fact. Shirou wished it could have been under different circumstances, but in truth, Rin probably would have never permitted it.
She was embarrassed of her weakness, and after he’d fingered her back door to climax after climax, she’d made him swear to never even think about going near her ass again. Shirou figured he was somewhat in the clear, because right now, it technically wasn’t HER ass, so long as Ishtar was in control. That said, Shirou pounded away into the goddess’ back door, his fingers digging into her pert posterior as she immediately climaxes from the penetration of his shaft.
“Why does it feel so GOOOOOD?!”
Shirou just laughs, and spanks Ishtar as he fucks her from behind. The bound goddess cries out from the sudden smack, and her eyes roll up in her head quite humiliatingly as she shakes and shivers her way through yet another orgasm. They don’t stop either. Rin really IS weak back here. It has to be the most sensitive part of her anatomy. Not even Ishtar, a goddess of lust, is quite able to properly handle what Shirou is giving her.
Leaning over the bent over body of his lover, Shirou grabs a fistful of her hair and drags her head up.
“Ishtar.”
Gasping for breath, it takes the pseudo-Servant a bit to get herself under control enough to respond.
“Y-Yessss?”
Grinning, Shirou gives her a particularly vicious thrust, drawing a pleasured cry from her lips. He waits for her to recover before he speaks again.
“Ishtar. Say it.”
“N-No!”
Growling, Shirou rapid-fire pistons his prick in and out of her asshole, sending her in a spiral as she screams bloody murder.
“Say it!”
“Y-You beast! D-Damn you!”
Smack!
“AH!”
“SAY IT!”
“I S-SUBMIT! I GIVE UP! Y-You win! Fuck me, damn it! Fuck me, fuck me, FUCK MEEEEE!!!”
Shirou does just that, ramming into Ishtar from behind with greater and greater force, until he finally cums a second time, his seed pumping into another hole as Ishtar’s eyes roll back once more, her tongue hanging out of her mouth obscenely as she slumps forward, passed out before him. Staring down at her, Shirou slowly pulls his cock out of Rin’s back door. He licks his lips as he moves off of the bed and to the side of it.
“Rin… Rin!”
Slowly, Rin’s eyes open. The red that signified Ishtar’s possession is gone as she blinks and looks to him. And the scowl that spreads across her face is ALL Rin.
“Shirou… you bastard, I can’t feel my d-damn legs…”
Chuckling a bit, Shirou just lays down beside her in relief, letting out a happy sigh.
“It’s good to have you back Rin.”
“S-Shut up… and get me out of this humiliating position! No one can ever know about this, not even Saber!”
Before Shirou can even move to get up, the door to the hotel room bangs open, and the aforementioned Saber rushes in, invisible sword already in hand.
“Shirou, I’m… h-here?”
Saber slows to a stop as she stares at the sight before her. Rin’s looking her way with wide blue eyes, while in a very compromising position. Meanwhile, Shirou sits up and slaps a hand down on Rin’s upturned ass, a slightly out of character grin across his face. But then, it’s easy to grin when you’ve just fucked your girlfriend’s ass so hard the heroic spirit possessing her had to take a nap.
“Don’t worry Saber. I’ve got it all under control.”
Rin was probably going to beat him later. SOOO worth it.

The defenselessness of Tohsaka's butt is a well documented phenomena.
