*****

He held her firmly by the waist, keeping her safely held in his hands as she remained hoisted on his bucking pelvis with her anus being plunged by the man's cock in a grooving tempo. Soft, hefty claps of flesh echoed out into the air with Ishtar's labored grunts of ecstasy constantly coming out of her lips as this went on.

"Ahh..ahh...ahah..aahh..aahh..aahh..aahh...Shirou..! Mmnghmhhmm! Aahhhhhhhh! It feels so good..! Sooooo....good! Dont stop fucking me, even after you've come. I want it more, and more, and more....! Uuaaahhhhhhhh!~" Ishtar cried out, bringing both hands behind his neck as she allowed Shirou to carry her fully within his hands. He lifted her a little so that her flawless ass was no longer resting on the windowsill completely and instead, pressed her lower back against it as he started fucking her harder.

In and out his cock went, plunging wetly into her anus to where the Goddess was undulating wildly against his frame with delight. Their bodies meshed together with incessant claps of skin leading Ishtar into another haze of sexual pleasure as she pulled Shirou onto her lips for a deep, erotic, tongue-swallowing kiss that he was compelled to receive while fucking her faster.

"Mmnhmnhm...sllrpp..shlurpppp..sllrp..sllrpp.mnhmm! Uugh..uuuh..unngh..mnghmm! Ishtar..! Aaanghh!~" Shirou moaned into her mouth, feeling the slick and slimy orifice of her anus begin squeezing him tightly at a very gradual pace while this went on. Soon enough, Shirou began bucking more intensely into her rump, enjoying the soft and supple flesh of her ass as it kept bouncing rhythmically against his pelvis the more he threw it into her from this position. Ishtar was having trouble keeping her grip going as she held onto the windowsill for dear life while losing herself in the pleasure all the while. Her tongue languidly rolled around his mouth, wrangling his tongue in a sensual yet feverish saliva-drinking exchange that made Shirou mew loudly in response as she couldn't get enough of this man.

"Hmmnhhmhh..Sllrpp..shlurppp..sllrrppp...shhhuuupp..Shirou....! Mnhghh..mmnghh..ngh...mngghhh..mmh..mh..mmh..mnghghmmmm! I'm getting close...! Aaaahhhhh!~*" She wound him moaning into his mouth between wet kisses, often muffling her words as she couldn't bear to be without Shirou's lips glued to her own. Ishtar was head-over-heels in love with this man and wanted him all to herself for ages to come, regardless of how or when this Singularity will end. She brought one of her hands up to wrap around the back of his neck, leading Shirou to exert more strength in carrying the slender Goddess in his hands. Her legs remained bolted outward from above his shoulders as she could feel his massive cock plunging deeply into her anus. 

Such a foreign, intense, passionate rutting inside of the one orifice she had never pleasured till now had Ishtar's brain turning into mush. Were she not swallowing Shirou's lips into her own, she'd be smiling a goofy grin of pure intoxicated ecstasy. She was beginning to feel her asshole tighten some more amid the ongoing flesh-clapping coitus they were indulging together. Clap after clap, again and again, Shirou kept plunging his thick cock directly into the divine asshole of the Goddess Ishtar and gradually felt her insides clutching it strongly the harder he pushed it in. It was as though he was plunging the insides of her body with how rough yet precise he was, making her croon loudly from inside of his lips as their tongues mingled messily together before she threw her head back in euphoria.

"Aaaaaaahhhh! Aaahahh..aahh...aahhh..aahhh...aaahhhh! Oohhhh...Shirou-Kun! Shiroouuuuuuu! Aahahh! Mnghmmm!~" Ishtar brought her other hand up from the windowsill to begin stroking one of her breasts to the ongoing motions of their bodies clapping together. She bit down on her bottom lip and started squeezing her eyes tightly together as the intense rush of orgasmic release was well on its way to flushing throughout her system. Her eyes peeled open into a half-lidded smile of utmost devotion and lustfulness when directed at Shirou, showing him just how crazy this  Goddess of Beauty and Fertility was for the lone master of Chaldea. "S-S-Shirou...! I'm getting close..! Oohhhhhhh...God! It's...it's....going to hit me hard..! Like a tidal wave..!  You...you're plugging my ass so...much... so intensely..! It feels...gooooddd...aaaaaahhhhhhhhhhh! Oohhhhh Shirou..! I'm cumming...!~"

Ishtar threw her head back and at the same time, Shirou clutched the Goddes's thighs and ass tightly together from within his hands, gripping her firmly as he felt the tinder squeeze of her rectal cavity as she gushes in orgasm all over his crotch! His dick felt the squeeze of her anal muscle and it was causing Shirou to grunt stiffly from behind his clenched teeth, leading to him bucking into her just a few more times before shuddering in orgasm himself..!

"Hmngghghhhhh! Ishtar....!Uuunngghhhhh! Here..I come...! Hmphhh!~" He said while holding her close and enjoying the feel of her incredibly soft skin pressing against his as he felt his cock lurching stiffly from inside of her ass, sending thick ropes of sperm directly into the woman's bowels..!

Spplurrt....spplurrt..spplurrt..spplurrt....spplrrt..spplrt....spplrrtt!

Ishtar felt the rush of sperm flooding into her body once again, this time from her once untouched asshole as she felt the goo of his seed filling up her anus right away. It was such a foreign sensation and it made her shudder briskly in bliss, shiver again and again as they let out their orgasms together with each other's arms.

'This feels so good...! Ooohhhhhh! It was positively divine...! Yes..! I could get used to having Shirou-Kun fuck me like this...! Eeeeaaahhhhhhh! If only Ereshkigal could join in on this somehow...! Uuughhh! I'd hate to be her and be missing out on this....!~' Ishtar thought, shuddering incessantly in sexual release while unaware that a certain Goddess of the Underworld stood ready in front of her large body mirror with her hands glowing with golden energy. They were magically linked to an extravagant Hourglass nearby which brimmed with radiant energy connecting to both Ishtar's and her own Spirit Cores, ready to trigger a certain 'Displacement' effect upon her command.

....

"And once he's done pulling out of her, that's when I make my move. Ah--! There..! Shirou-Kun is...setting her down gently by the windowsill now. Perfect...! Oohhhh....and here's still hard too! Here I come, Shirou...!~" Ereshkigal said to herself excitedly, gushing like a young girl as she tapped into Ishtar's Spirit Core and chanted the Mantra to her Spell of Displacement. 'I won't be missing out on this anymore! Uuaaah....!'

With a flash of Golden light blinding the area, the Spell was activated to absolute effect and with certain 'additions' made that had a certain Goddess of Beauty blinking in surprise a few times as she stared back at her reflection in a large body mirror somewhere that felt dreadfully familiar.

....

"Eh...? W-what...where....?! Huh...!? How in the Hell did I get here?! This is Ereshikigal's room, isn't it...?!" Ishtar asked herself as she stared at her reflection once her post-coital fever trip wore off and she was suddenly standing in a dreary bedroom somewhere that she'd never consider living in herself. It looked like the interior of someplace in a dark, soulless, cavern filled with dark teal-colored rocks and carrying an air of Death all around her with a series of blue-lit torches nearby.

She was standing inside of Ereshkigal's robe holding her shoulders and wondering just how or when this happened while she was enjoying sex with Shiriour Emiya again. Her long, silken hair was now blonde yet the mirror showed her still having it black since the Spell only swapped Spirit Origins around. Ishtar's face was still the same despite the two being twins, yet Ishtar wasn't in her usual clothing at all and she felt her powers change to become far more oppressed than when she toured the Underworld the last time she was. 

Swiftly checking her sides and looking around in a frantic frenzy of utmost agitation, Isthar's twin tails pointed outward in fury as she realized what her sister had done and grabbed her head with a howl.

"Eyeeaaaaaahhhh! Ereshkigal, you bitch..! You switched places with me again, didn't you...!? Uughhh! Of all the times...! And of all the nerve too! You could've just asked me and we could've worked something out if you felt that strongly for Shirou-Kun, you know..! Grrghhhh!" She howled loudly, throwing her hands up in the air in a comical, tantrum-throwing manner as she stomped around the dreary bedroom in frustration. Wearing Ereshkigal's usual accessories as well as her more concealing clothing truly didn't suit Ishtar's taste, she was visibly disgusted and greatly annoyed as she plopped down onto the other Goddess's bed with her hands really wanting to grab somebody to strangle right now. 'Hmmmm, she must've felt strongly for Shirou too if she did this. This...Displacement Spell seems stronger than the last one she used and ...if I'm right...she probably plans to spell all night over there, wearing my face and using my body. Was she that much in love with Emiya? To even...do this to me? Hmph, bitch....! I can't wait til it's over and I blast my way through the Underworld again just to teach you a lesson, but for now...fine. Go have your fun, you little....!"

Ishtar, despite her frustration with Ereshkigal just now, felt impressed by the blonde's tenacity in scheming this little trick just to get some time alone with Shirou. On one hand, she was happy for the girl finally getting to experience the love and 'magical' sexual affinity Shirou had when it came to women, but on the other hand, Ishtar hated being taken for a loop by none other than her Sister Goddess.

"Well, nothing to do except kick back and just relax here. At least the bed is comfortable enough...." She muttered bitterly to herself.

*******

Opening up her eyes again and looking out at the world with sunlight, fresh air, and greenery with life being abundant all over, Ereshkigal realized she was now in her sister's body after the Spell had successfully worked. She was set down gently by the windowsill just after feeling Shirou's cock pop out of her gaping asshole, leaving the Goddess to shudder briskly in response for the feeling was still fresh. Ereshkigal had to lean against it as she looked back over her shoulder at the beauty of Uruk once more, and then she looked back at Shirou who had his erection still retaining girth even after all the rutting he did with Ishtar earlier today.

'I did it, I'm here...! The Spell worked perfectly and it seems that...Shirou-Kun doesn't recognize that it is her yet either. Hee hee...! Oohhhhh..he's still raring to go too, and I'm going to enjoy this to the fullest while I'm up here..with him. Sorry about this, Ishtar, I'm sure you're probably seething angrily right now...but finally there's something I truly want that I can get, and I am certainly doing whatever it takes to get it.~' Ereshkigal reasoned with utmost delight and giddiness as she took a moment to recuperate while her ass healed on its own. Being a Goddess, nay a Divine Entity attached to a Servant's body made her vitality and physical prowess above anyone else's in the world. The feeling of sore pain left her buttocks quickly as she nursed one side of her rump with a smile, looking at Shirou lovingly as she bounced off of the windowsill to provocatively lay atop the bed. "Shirou-Kun....would you please...make love to me now in a more...romantic way? We've been..ahem... going at like animals this entire time so how about we do things a bit more intimately, yeah? Like say, reenacting our first time together in this bedroom?~"

"Huh, Ishtar....that sounds like a good idea. You normally want it so rough and...drag me off to ride me against my will sometimes if I have things to do for my mission, but certainly. I don't mind doing things more romantically with you. Do you happen to remember how we did it at the start? I think it began more with you getting on top of me and seducing me right on the spot, this time I'd like to be in the driver's seat this time around if that's alright.~" Shirou proposed, making Ereshkigal bristle energetically with excitement as she quickly checked her reflection in a nearby tableside mirror to make sure her face and hair resembled Ishtar's. There was always a chance her hair could flicker back to blonde if she wasn't careful like last time when Shirou first spoke with her in the forest, but now she was sure her disguise was safe.

She rapidly nods her head with a loving smile and lies back onto the bed completely while Shirou begins crawling onto it toward her with his eyes leering at her with a suave smile, completely charming the Underworld Goddess all over again.

'Eeeeeeeeeeee...! This is turning out even better than I had hoped...! Oohhh, come and take me, Shirou-Kun. Please...make love to me all night long. I can only pray that Merlin, Mash, and the others don't come back here anytime soon and ruin everything.' Ereshkigal thought to herself as she brought her hands up to Shirou's allowing him to interweave his fingers with her own as he let the thick rod of his member caress her inner thighs, causing her to shudder briskly upon contact. This perplexed the man just a little since it felt like she was experiencing their first time all over again, but ultimately, he put any thoughts about her reactions behind him as he leaned down to wrap his lips around hers in a deep kiss.

"Hmmnhmmhm...sllrp..shlurpppp.....sllrp..mnhmhhhgh...Sllrp..mnhm. Ishtar...~" Shirou mewed into her face, feeling his eyes close as he hungrily swallowed her saliva once again, albeit with Ishtar kissing him back more tenderly than before. The Goddess moaned softly into his mouth, spreading her lips apart so that their tongues intermingled in ways more sensual and more romantic rather than erotic. This was a nice change of pace for Shirou as he began to exert more control over this situation, he started clenching his hands around hers tighter and started swallowing her tongue a bit more with newly added vigor. Ereshkigal was over the moon with delight right now as she curved her spine a bit from underneath him, pushed her naked breasts out, and slid one of her legs along the surface of his thigh as they got more heated up with each other. Her tongue elegantly swiveled around his own in a myriad of swift, slurping strokes that allowed Ereshkigal to savor every moment of this as things gradually progressed. 'He's such a splendid kisser...mhmhmm...! Ishtar doesn't know how good she has it by having this man ravish her the way that he does. Oohhhh...!~'

Closing her eyes and basking in the moment as they spent another five minutes making our hungrily with each other and drinking each other's saliva while Shirou's dick pressed against her folds, Ereshkigal felt now was the time to experience what she had been missing out on. Lurid suckles of lips came about in moist engagements of suction for another minute till she pulled her lips back and gave Shirou a knowing smile while nodding her head.

"Please...go ahead and put it back inside of me. I'm begging you, Emiya-Kun.~" She was giddy beyond life as he started leaning back, spreading open the woman's legs with his thighs and aligning the tip of his cock with her folds for a direct push of his waist. Shirou had to retract one hand and guide it in securely, making sure that the tip nudged the opening of Ishtar's sex when he realized something.

"Hmmm, you seem...as tight as you were before when we first fucked, but then again...I think it must be an aspect of your Divinity, right? Because every time we have sex you always seem as tight as you were that day, only now you feel....a little tighter...almost like a virgin. Weird, huh?~" Shirou pointed out and Ereshkigal, beginning to panic a little, shifted her eyes from side to side pretending to be in the dark about what he was talking about. She had forgotten that her chastity was absolute even when it came to switching bodies, so she hoped Shirou didn't realize anything about this switch-a-roo as he pushed himself in. "Hmnnghghh!~"

Squeeellecch!

"Eeeeyyaaaaaaagghhhh! Unghghh! Oohhh! Shirou...! Mnghmm! Yes..it is..a Divine attribute of ours..to always rejuvenate our bodies..as well as regrow our hymens if we happen to be Goddess and Servant rolled into one. UUaaaaahhhhh!~" Ereshkigal lied as she felt the intense pain of surrendering her cherry to Shirou's immense dick as he pierced her insides all the way through and drove deep inside of her folds. Her legs kicked up into the air with feet lurching about wildly as she felt him go balls deep, causing her body to shudder incessantly with sensation. 'He is so big..! So long...! It feels..so painful yet it also feels very good..! Uuaaahhhhhhhhh! Oohhhhhh! This is what I've been missing out on all this time! I do not regret sticking Isthar in my place as I take control of her sex life here..! Mhhmm...!~"

The slick visage of her pussy covered nearly all of Shirou's length as he pushed through, resting his groin directly above hers as he pressed against her body from above in a basic, vanilla missionary position with Ishtar's arms sliding up to wrap around his neck. It was a heated moment where he felt the slick sliminess of her tight, virgin folds swallowing up his cock all over again as he got re-acquainted. It was such a profound feeling to have a Goddess's womanhood clench tightly around his cock, let alone take their innocence which made Shirou begin to rut heavily into her from above with smooth undulating motions of his waist.

"Hmnghghhmhh! Here I go..! Uunnh..uuhh..uuhh..uuhh....uunn..mnghm..mnghhhh! Christ..! Ishtar..! Aaahhhhhhhnghhh!~" Shirou cried out softly as he felt the powerful Goddess's divine womanhood clutching his cock even tighter as he went along bucking into her waist with gradually increasing force. It was in and out that his meat went, plunging into her sodden wetness while the moisture from her twat lubricated his shaft to allow for more motion. Shirou was becoming possessed by pleasure as he felt the woman's twat clutching him tight, guiding his primal instincts as he began quickly bottoming out of her in the way that she always wanted. Their lovemaking was still slow and passionate for the most part and Ereshkigal was loving every minute of it as she felt Shirou's length bottoming into her womb.

"Aaahh..aahh...aahhhhh..aahhh..aahhhh..mgghhh! Shirou..! Shiroouuuu! Mnghh! Uuh..uuhh..uuhh.uuhh...uhh..uuhh...hhahaaahhhh! K-keep going slow..! I..I want to savor this..! I love everything about you! Everything...! Uuyaaahhhh!~" Ereshkigal let out as she curved her spine a bit more, causing her tits to scrape against Shirou's pecs as he continuously bottomed out of her pussy when her legs began crossing behind his neck. Shirou found it odd how she was behaving yet was still blinded with lust and sexual need for release that he paid Ishtar's mannerisms no mind at all as he dove in to start kissing up the surface of her neck. He could feel her shivering intensely with ecstasy as he drove his cock deeper, touching the back of her womb after pressing it so far it bypassed her cervix and made her insides coil tightly around him in response. 'He's in so deep..! Sooo deep inside of me..! If I was a regular human, I'd probably become pregnant with his child if he decides to unload it all inside like how he does with Ishtar..! Mnghmm! Uuhh..uuhh.uuuh..uuahh! This is everything I dreamed it would be and more..!~'

Together they rutted about feverishly atop the bed with Shirou's buttocks rising and falling with every hard thrust he made between Ishtar's legs. They clutched tightly around his backside ankle across ankle with him feeling the slick squeeze of her pussy guide his instincts into going wild. He nipped at her collarbone and ran one of his hands along her upper right thigh, embracing her completely as she held onto him with fingernails digging into his back.

"Nngh..nghh..nngh..nngh..mngh..mnghh...mghghhhh! Ooohhhhh...you feel so tight right now, Ishtar..! Uunghhh! You sound so...cute today too..! This is different from how aggressive you are..earlier today in the..nghgh.. alleyway, but I'm not complaining..! I love everything about you...and will please you as many times as you want...! Ahh..ahh.a.hhh...aahhh..aahh..aahahhhh....! Speaking of which, I may be coming soon too because your pussy is squeezing me so tight..! Uuannghh!~" Shirou mouthed into the crook of her neck, kissing it some more as he held onto Ishtar's waist for dear life using one hand to wrap around her backside and the other to hold her waist into his rocketing pelvis. 

His dick plunged in and out of her sodden sex completely with increasing moistness coming out of her folds for the duration of twenty long, utterly euphoric minutes of passionate lovemaking till he felt Ishtar's pussy clench tightly in an orgasmic blitz of explosive proportions. Shirou had pushed the head of his dick directly into the back of her womb, causing the Goddess to curl her spine sharply as she let out an almighty scream of ecstasy and elation with her lips curling upwards into a drunken smile.

!

"Eeeeaaaggghhhhhhhhhh! I'm cummmiinnngg...! Ooooohhhhhhh! Shirou..!~" Ereshkigal cried out, shedding tears of happiness as her entire body writhes in orgasm underneath this stud of a mane. Her pussy clenched and squeezed around his cock voraciously, milking the man for his cum which she received in plentiful amounts after Shirou buckled into her body a few more times before he came next.  He pulled his cock up one last time to the tip and proceeded to slam everything down inside of her convulsing pussy before feeling the rush of sperm come gushing out.

"Uunghgh..unngh..unghghhh! Here it comes..! Gaaaghh!~" He grunted into her neck and held onto her body as he felt the incredible squeeze of divine vaginal muscle suck everything out of his balls. Thick ropes of sperm flew straight into Ereshkigal's body with absurd amounts of it readily filling up her womb and to an extent drowning out her uterus in the process.

Spppllrrt..spplrrt..spplrrt...spplrrt..spplrrt..spollrrt....spplrrtt!

She wrapped her arms around his neck real tight and made her eyes reflect glowing little hearts as she held onto him for a while longer, enjoying the reflexive action of her pussy taking in and sucking out all of Shirou's sperm into her depths. Little did she or Ishtar know that his seed was actually having a profound effect on their bodies, namely their wombs since they were still both Pseudo-Vessels whose vessels had been human before their Ascension as Divinities. Shiround ground into Ishtar's waist some more, letting every ounce of sperm he had at the moment come out for well over a minute until he was done.

"Guah...! Hot damn..that was..intense..just like our first time too. Whew..hehehe, are you still...wanting to do more, Ishtar? Because..seeing you all sweet and innocent just now reminded me how cute you really are..and I'm ready for a bonus round if you'll have it with me.~" Shirou asked after he pulls his cock out of her sodden insides with a wet splotch of moisture and sperm, letting the latter spill out en masse when Ishtar suddenly shot up and switched around their positions to where she was now on top.

!

"Ugnhh! Yes..! I am ready, Shirou-Kun! I want to do it more with you...! Heheheh..!~" Ishtar let out, running her tongue across her lips as she gave Shirou a hauntingly bedazzling smile of utmost desire when grinding against his waist. Her groin pushed up against the stiff underside of his cock which, to her great surprise and delight, remained hard even after all that.
