Finis Chaldea, the last hope of humanity. Initially, a place Shirou had come to as a simple handyman... sent by the Clock Tower to spy on the actions of the leaders involved. In theory. Mostly the side effect of him and Rin trying to avoid a sealing designation and so needing to keep the Mages' Association off his back.
Not that he regretted taking the assignment for one second, especially after he became involved in the effort to save humanity's entire existence.
Truthfully, part of him was glad for the nature of the Grand Order, and the fact that he was not actually the Master for Chaldea - it was simply not a role that suited him, and he was much better off being Ritsuka's sword... swords, plural really... than he was being Chaldea's leader. With a sword and a shield by her side, the almost distressingly similar Master of Chaldea had found plentiful and overwhelming success, and gathered many allies under her banner.
Heh, banner. Speaking of which...
"You seem amused, Mr. Shirou."
One of Ritsuka's servants, one of the oldest and first to be summoned. A great aid and help during the events of Orleans... and a bit of an obsessive weirdo regarding the people she saw as her younger siblings. Sometimes, Shirou could lose himself in the pang of a love lost, when he saw her face, so similar to the King of Knights'... But then, she had her ways to cheer him up. She passed him a water bottle, and a towel, as Shirou got off of the improvised weight training machine.
Another thing he was very thankful for? The access to teachers of legend and equipment created and enhanced by the greatest spellcasters of the human order. He could probably even give Rin lessons with how much he had learned about magecraft, and how much more he had learned about himself and his reality marble, let alone his immense progress in martial arts and general combat. He hardly ever needed to rely on borrowed skills these days, after Chiron and Scathach had beat combat into him.
The bottle was emptied in a single go, and he sighed. "Thank you," he said. "I didn't keep you long, did I?"
"No longer than usual," she said, giving him a bright smile. "Have you heard the good news?"
"If this is a Jehova's witness pitch..." Shirou muttered, giving a low chuckle. "No, I've been training all day."
"We're both off the roster for tonight," Jeanne said, as she accompanied him. They chatted of unimportant things and details that didn't matter, chitchat but warm and comfortable. The halls of Chaldea were immaculate, and Shirou was easily able to follow them to his room, accompanied by the blonde.
A rare day when Ritsuka would give them a simultaneous half day off. Given how pressed for resources Chaldea was, and how expensive it was to keep the place running, they were working almost 24/7, and it was a wonder that people could take days off at all... without involving a certain, purple haired monster that wore Sakura's face. The less Shirou had to deal with the abomination known as BB, the better, in his opinion.
"Ah, that's... great," Shirou said, not really finding the right word. "I guess we could-"
Jeanne pushed him into the door to his room, and reminded him that as strong as he had become, he was no heroic spirit, for she was easily able to launch him onto his bed. "We haven't really had time lately," she said, as she was unbuttoning the backless shirt she decided was good enough for casual wear - but only a few buttons.
Shirou tried to get up, but she was quick and knew what to do. "Jeanne, what are you-"
She was on her knees before him, and with a cheeky grin, she reached for the waistband of his sweatpants. "I'm helping you relax," she said, "Now please-"
He lifted his hips at her prompt and his pants, and underwear, were off in an instant. Despite his pretend resistance, his body knew what was coming and anticipated it dearly. She grabbed his half-chub and giggled, leaning down and kissing the skin covered tip before taking him into her mouth.
"Jeanne- this isn't-"
She didn't respond, instead suckling and licking at him, quickly bringing him to full mast. She pulled back and licked her lips.
"I haven't even had time to shower," Shirou protested. "I'm all dirty."
"Then let this helpful big sis clean you up~!"
Oh, so that's what'd gotten into her. Well... "Okay," Shirou said with a sigh.
She let out a low chuckle,and leaned forward. He spread his legs a bit further, giving her proper access. While the top of her shirt was still buttoned, it really wasn't doing much to prevent her from taking his stiff prick and lining it up with the valley between her breasts. "It's so hot and stiff," she said, looking him in the eyes as she held him, "my breasts almost burn and I haven't even put it in yet."
Shirou gasped as she began lowering herself, the mushroom head of his prick slipping into the slick- already lubricated, what a minx - passage she'd created, the thick and wonderfully soft globes enveloping and wrapping around him. His groans and moans seemed to drive her further, as her own face was flushed now, just as red as his.
Without further preamble, Jeanne began performing an act she was well practiced on, and with one hand holding him in place and the other on her tits, she gave Shirou the finest titfuck a man could ask for, enveloped in the holy milkers of a big sis type saint, a dirty and slutty act performed by a pure and incorruptible maiden, somehow all the filthier for it. The forbidden paradise contained within her shirt was unbelievable, hot, warm and soft, yet with just the right firmness...
The pleasure mounted, and Shirou could deny neither himself nor Jeanne. "I'm- I'm gonna cum!"
"Already?" she asked. "It's only been five minutes!" she giggled. "I guess you're backed up yourself!"
Shirou was, he had to admit. He didn't really have the time or inclination to take care of himself, and Chaldea was plagued with incredibly beautiful women, many of which were seductresses of legend. They sometimes made it a point to flaunt their bodies to him as he passed by, and it drove him mad. Mad with desire and lust, though he didn't regret that it had led to this situation, where a loving saint had decided to help him with his problem.
Finally...
Jeanne yelped and moaned as she felt her efforts bear fruit, his cock unloading a thick helping of babymaking cream all over her tits and shirt, staining it, the front of the shirt now remarkably darker as it clung to her breasts, plastered with cum.
Jeanne laughed and pulled off of him, his prick moist and messy.
Within moments, Jeanne removed her shirt and wiped the remainders of semen on it, before tossing it away. With a shove, she pushed Shirou so he was laying on the bed, and she pulled down her dark shorts, but did not remove her thigh highs. She made sure to give him a show of it, turning around and pulling them down while bending over, to show him the full curve and shape of her ass, as well as show him that she wore no underwear.
Shirou hadn't flagged, and the sight made his cock twitch and throb, anticipating what was coming.
She straddled his hips, and looked down upon him. "You're not disappointed?"
Shirou shook his head. "I know how it is," he said.
Love be what it may, she was a Bride of the Lord, and a holy, pure maiden. And she had to remain as such.
Her vagina was off limits. Neither Shirou nor anyone else would be permitted there.
Jeanne lined him up with her anus instead. An expression purely of love, an act done to share in comfort and affection, rather than animalistic mating for procreation. With an expression that spoke of gratitude and love, she lowered herself, and Shirou groaned as the impossibly tight muscles of her ass split and allowed him entrance, opening up for him to invade them.
They rarely had time, but these few moments were precious, and neither of them lost time with pointless words. Jeanne leaned forward, her tits now pressing against Shirou's chest while his cock almost slipped out of her ass, and their lips met in an almost comically out of place, pure and chaste kiss, a peck on the lips. It lasted a short duration, before Jeanne returned to her proper sitting position.
Her hips' movement caused Shirou to sink back in and she moaned long and loud, before her hips began the pistoning motion that both of them loved, the quick and frenetic pace as they sought to drown in each other's body.
Her ass was hot and slick, welcoming of him yet so very tight, trying to prevent intrusion yet unwilling to let him out, a contradiction and paradoxic hole that seemed to exist for the purpose of pleasuring men, a pure, incorruptible and ever pious woman with the body of a succubus that tempted men into sin... that was Jeanne d'Arc, a woman who Shirou had once thought not to pay attention to, lest he be lost in her resemblance to a lost love, yet with whom he had found comfort and, perhaps, even a new love.
Jeanne's baby blue eyes opened and she looked down on him from above. "S-Shirou, I'm- I'm going to-"
"Me too, let's do it together, let's cum together!"
"Yes!" she shouted.
No more words needed to be exchanged, as their night was capped off with both of them racing to meet each other at the very end of their line, both trying to make the other be first, to pleasure their partner...
In the end, neither could say who it was, as both of their voices exclaimed their orgasm together, and though both of them would go for repeat performances all night, whichever of them had the win, none could say.
