"Erm, well, she's a bit... tied up at the moment", said Shirou to the person on the end of the phone, presumably her sister based on the ringtone.
Sakura groaned into her gag at Shirou's terrible pun. She was bound and naked on the floor of the bedroom, painful-looking clamps on each nipple and several vibrators inserted inside her, keeping her constantly and frustratingly aroused without ever quite providing enough of a sensation to allow her to come to orgasm. She had been being tormented in this manner for some time, and was now very frustrated at the lack of an orgasm. Shirou liked to push her to the limit before he gave her release but, despite how horrible it felt right now, she knew from experience that the orgasm he would eventually give her would be worth the wait.
"What do you mean, 'Rider is missing'?" he said, clearly somewhat irritated at the sudden interruption to what had been a very enjoyable session with his beloved. "You did what?"
Seeing that something was clearly wrong, Sakura summoned up a shadow tendril and cut through the ropes binding her hands and feet, before reaching up to remove the gag and the various devices Shirou had been using to tease and torment her.
Sakura stood up, her body still bound with the standard Shibari bondage technique that Shirou had learnt to use, and walked towards her husband.
"Darling, what's wrong?" she asked, the arousal still clear in her voice.
"It's Rider, she's disappeared. Rin thinks she's transported her to another world...".
"What?" Sakura roared, grabbing the phone. She was irritated at having her fun interrupted, and highly frustrated due to the long period of orgasm denial she had experienced. She really was not in the mood for this.
"You did what, Nee-san?" she shouted.
"Well, I was doing an experiment, and it exploded, and Rider vanished. I think I sent her to another world...", her sister said, sheepishly.
"You moron!" Sakura shouted. "Can you bring her back?"
"Erm, maybe. I need your connection to be able to track her, though...", her sister replied, still sheepish.
"OK, we'll be back soon...", Sakura said, sighing, still very horny and extremely irritated with her sister.
"Shirou, we need to go back home, Nee-san needs us to help bring back Rider", she said calmly, despite the anger bubbling inside her. "Can you help me undo these knots?"
Shirou sighed before moved towards his wife and began to do as she had asked, ignoring the painfully-throbbing erection that wanted him to continue where he had left off. Once she had been untied, they quickly got theirselves dressed, and quickly packed their things and tidied the house so that no-one would realise they had left in such a hurry.
Damn, how are we going to get everything back home? she thought.
They had driven here and, whilst Sakura could in principle transport a car, it would be more effort than she would like and, besides, given that the exit point was in Rin's living room it would not be a great idea....
Admittedly, it would serve her right..., she thought for a moment, before dismissing the idea.
Actually, I'll just use a bounded field to make people ignore it, someone can just come up here and collect it later.
"Dieser Ort ist normal. Nichts ist falsch. Es ist, um ignoriert zu werden", she chanted.
It was only a quick and simple bounded field, the car was, of course, still entirely visible, but it would just provide enough of a nudge to persuade anyone who might arrive before Rin could collect it that it was not out of place. After all, it wasn't entirely unreasonable for there to be a car parked there, the spell would simply discourage people from questioning why it had not moved just yet.
"Schwarzkasten", Sakura chanted, and a small shadow appeared.
She still didn't really like travelling this way, but it was simply too convinient to ignore, especially when they were in a hurry to get back.
"Wachsen. Aufbewahren".
With that, the shadow grew larger, before consuming her, Shirou and their luggage. For a moment, everything went dark, before they arrived in what seemed to be a corridor. Of course, in reality, it was simply Sakura's mental image, designed to assist her in finding which of her many shadow familiars she wished to emerge at.
She walked down the corridor for a few moments, until she saw the door signposted "Nee-san's house".
"This one, Shirou", she said with a smile, and the two of them walked through the door and emerged into the familiar surroundings of her sister's living room.
"Nee-san, we're here!" Sakura shouted, clearly annoyed.
Rin walked into the room, obviously extremely upset by what she had done, and worried about what would happen.
"What the hell happened?" said Sakura, angrily.
"I was performing an experiment whilst Rider and Kiyoshi were playing outside. Something went wrong, and then Kiyoshi came running to me saying that Rider had vanished. I don't know where she's gone, but I think I can trace her with the help of your contract...", she said.
Sakura glared at her, before sighing.
"Well, OK, let's get moving. Rider can't survive for more than a few days without prana, and I don't want her to die...", she said, clearly upset at the thought of losing one of her oldest friends.
"OK, I'll go and get things ready, I'll call you when I'm done", she said, turning to leave.
Just as she reached the door, she turned around once more.
"And, I'm sorry, Sakura. I do hope Rider is OK...", she said with genuine remorse.
Sakura, feeling somewhat unclean, decided to have a shower whilst she was waiting, before she and Shirou returned home (using her shadow magic once more) and packed theirselves each a small bag, containing some clothing, some of the old-fashioned paper money that they happened to have lying around and any equipment they might need, such as phones and anyhing they needed to use to fight. Then, they returned to Rin's house and, going to the location where she stored her jewels, "borrowed" a few of the unused ones, for bartering in case the location they were going to did not accept their paper money, as many shops did not in the modern era. Of course, Sakura would "ask" for permission before leaving, she wasn't going to steal from her sister, but, given that this whole thing was Rin's fault and that Sakura had provided her sister with plenty of funding over the years in any case, she felt it was only fair.
Finally, they heard her calling them, and proceeded down to the basement where she performed her magical experiments.
"OK, I've re-created the experiment. Sakura, I need you to hold this", Rin said, passing her a jewel. "It'll allow me to amplify your connection to Rider and send you to whatever world she's in".
Then, she turned to Shirou.
"And, you, take this. It'll allow me to keep track of you two, so I can bring you back or send more things to you", she said, passing him another jewel.
"OK, are you all ready to go?"
"Yes, Nee-san", said Sakura. "Oh, by the way, I borrowed a few of your unused jewels in case we need something more universal to use as currency. I'll pay you back later, hope you don't mind", she said.
"Yes, I kind-of do mind", Rin retorted. "Those are my gems, I need them for my magecraft."
"Yes, and I mind you sending my servant off to another world...", Sakura responded, angrily.
"Erm, yeah, well, on the other hand, you are my cute little sister, I guess I can spare a few gems for you...", Rin responded, sheepishly.
"Yeah, I thought so", she said with the sort of grin that would usually have been more associated with her older sister.
"OK, hold on to each other, this is going to be a bit rough, and if you get separated you might not end up in the same place...", Rin said.
With that, she began to chant in her standard Tohsaka-brand "German". After a few moments, there was a flash, and Sakura and Shirou felt theirselves being violently shaken around as they were dragged into the new world. In the commotion, Sakura lost her grip on Shirou's hand, and could feel him drifting away from her.
"Shirou!" she shouted, but she couldn't grab hold of him in time, and they drifted apart as she felt herself arriving in the new world. Still, she was pretty certain Shirou had ended up in the same place, at least, even if finding him would be difficult.
With a flash, Sakura found herself in a city that looked somewhat like Toyko.
Huh, where am I?
Sakura looked around for her husband, but he was nowhere to be found. Worse, her connection to Rider seemed to be faulty. She could tell that Rider was here and still alive, to her great relief, but she couldn't pinpoint her location, and there seemed to be no mana flowing between the two of them. It was as if Rider's end of the connection had been severed somehow.
Hmm, what happened to Rider, then? I think she's OK, at least.
She looked around a bit more, before noticing a guy in a suit of black armour walking along the pavement.
That's weird....
Before she could approach him to ask what was going on, though, she saw a car come speeding around the corner and slam into him, before going into a spin and stopping directly in front of the man.
Oh, God! she thought, running towards the stricken man.
As she did so, she noticed a woman with strangely-familiar white hair getting out of the car from the other side. Sakura approached approached the two of them, intending to do what she could for the man and to berate the woman for her recklessness and lack of care for others.
As she approached, she could feel the magical energy flowing from the woman.
Is she healing him?
“Oh, this is bad...”, the woman said.
Sakura came closer before speaking up.
"Excuse me, do you need any hel... I..Ilya?" she said as she noticed the woman's familiar features.
Hmm, no, she's much bigger, like an adult Ilya might look.
Still, she was clearly an Einsbern and, most likely, a homonculus of the same lineage as Ilya herself. Sakura was intrigued, and a little saddened by the reminder of the young girl whose sacrifice had allowed her to feel true happiness.
