[No one knew that Tohsaka Sakura had issued a mandatory command to you using a Command Spell.]
[After all, you and she already acted quite intimately.]
[So—even if such an overreaching demand was made, it would still be difficult for outsiders to discover.]
[Not even her older sister, Tohsaka Rin, could detect it without direct contact.]
At Homurahara Academy.
Tohsaka Rin looked at the scene before her, utterly perplexed. Her younger sister, Tohsaka Sakura, was walking hand-in-hand with her Servant, Ian, along the campus path, in an incredibly intimate manner.
"Sakura, you—!"
Tohsaka Rin wasn't against Tohsaka Sakura being intimate with her Servant. But this was Homurahara Academy! If they were so brazen, and a student happened to see them, the situation could become complicated.
However—as if she had already anticipated her sister's words, Tohsaka Sakura quickly offered an explanation. "It's fine, Sister. I've already checked... there's no one else around. That's why Mr. Ian and I are walking hand-in-hand. Besides—" Tohsaka Sakura looked at Ian beside her, her eyes filled with a passionate affection. "He... seems particularly enthusiastic because he hasn't seen me for too long."
"Particularly enthusiastic?" Tohsaka Rin didn't quite understand the meaning of that phrase.
"Yes," Tohsaka Sakura nodded. "Sister, look—" Explaining thus, the girl slowly extended her hand to the man. "Mr. Ian~"
[Your mind is entirely filled with the demands Tohsaka Sakura just issued using the Command Spell.]
[Its effect shouldn't actually be this strong—after all, your Saber class possesses exceptionally high Magic Resistance.]
[But after more than ten years of companionship, your emotional connection with Tohsaka Sakura is simply too deep.]
[This caused her commands to have an effect on you far beyond what was imaginable.]
[After all—subconsciously, you have already taken on the responsibility of fulfilling her desires.]
Ian immediately lowered his head and kissed Tohsaka Sakura's hand, like a loyal knight. That perfectly executed royal (courtesy/etiquette) filled Tohsaka Rin with envy. As the successor to her father Tohsaka Tokiomi's position as head of the family, she truly wished she could have a powerful Saber like Ian. But unfortunately—that possibility no longer existed. Saber belonged to her younger sister, Tohsaka Sakura; she would have to find another path.
However, Tohsaka Rin completely failed to understand the connection between this standard hand-kissing gesture and Tohsaka Sakura's earlier comment about "enthusiasm." This kind of thing could be done normally, couldn't it? Why call it enthusiasm?
And Tohsaka Sakura seemed to have, once again, predicted what her sister was about to say. The girl temporarily let go of Ian's hand, leaned into her sister's ear, and whispered, "Sister, do you know where there's a more secluded spot at school?"
"Hm? A secluded spot?" Tohsaka Rin blinked. "Why are you looking for a place like that?"
"Because—" Tohsaka Sakura whispered, almost boastfully. "Mr. Ian just told me... he really wants to do that with me."
"Wh-what?!" Hearing this, Tohsaka Rin immediately reacted. Her face flushed, but she quickly forced herself to calm down. "Sakura, you're not joking, are you?"
"Of course not." Tohsaka Sakura's tone grew increasingly shy, as if she would melt from sweetness at any moment. "Because it's not just Mr. Ian who has that thought..."
"I... have it too."
"..." Realizing that her younger sister indeed regarded the summoned Servant as her boyfriend, Tohsaka Rin said no more. She didn't like to criticize Tohsaka Sakura's actions. After all, it was the path she herself chose. Besides—Tohsaka Rin looked at the blissful Tohsaka Sakura, recalling what their mother, Zenjou Aoi, had mentioned that night. "If Sakura and her Servant could become lovers, that would also be a good option." This was a way to preserve one's life in the Fifth Holy Grail War.
"I understand." Tohsaka Rin put her hands on her hips. "Good thing I'm the student council vice president... otherwise, I really couldn't help you and Ian with this."
[Tohsaka Rin knows your and Tohsaka Sakura's thoughts.]
[She, using her position as student council vice president, borrows a set of keys.]
[You don't know where those keys lead, and Tohsaka Rin doesn't intend to explain.]
[You both walk up the stairs of Homurahara Academy.]
[Finally, you arrive at your destination—the rooftop.]
On the rooftop.
This was the highest point of Homurahara Academy. White tiles covered the ground, and iron mesh surrounded the area. Because it was so high, most people wouldn't notice it, let alone with school not even officially started yet. Tohsaka Rin locked the door, then put the keys into her pocket.
"Alright. If you're going to do that, this is definitely a good choice."
"Mm~" Tohsaka Sakura, in response to her sister, actually had her own little plan. Although she knew that Command Spells could forcefully make a Servant obey a certain demand, she was still somewhat uneasy. After all—this was the first time she had used it on Ian without any prior reference. Tohsaka Sakura naturally felt uncertain. Otherwise, she wouldn't have wanted to test it so quickly under her sister's watchful eye.
However—the facts quickly proved Tohsaka Sakura's worries were unnecessary. Although they had already done it many times in the sports storage room earlier, Ian still maintained almost the same level of activity. No. Perhaps, he was even more intense than before.
Tohsaka Rin watched her sister go from being grounded to barely touching the ground, then to seemingly soaring into the void. Her expression was one of pure enjoyment, and she seemed entirely unconcerned about her sister witnessing the live performance. The girl's magic circuits connected directly with her Servant repeatedly in the air. The connection between them also continuously strengthened during this process.
Finally—as the girl's head arched towards the sky, this breathtaking performance came to an end.
Of course, Tohsaka Rin also "received" a gift from her sister—the spray of liquid that erupted due to her excessive excitement.
"I-I'm sorry." Tohsaka Sakura turned her face away, her voice filled with shame. At this moment, her position was like a freshly retrieved package; Ian held her hands, tightly embracing her, her two legs straight up, above the height of her ears. The place used for connection trembled slightly, constantly dripping.
"Sister... I didn't mean to."
"I know." A somewhat embarrassed Tohsaka Rin pulled out a handkerchief and wiped the liquid from her sister off her face. "Sister isn't mad at you. But—"
"Sakura." The now clean Tohsaka Rin looked at Tohsaka Sakura and Ian in front of her. "Are you two really that excited? To be so worked up?!" Tohsaka Sakura could understand such behavior, but still felt it was a bit exaggerated.
"Mm... indeed." Tohsaka Sakura tilted her head up, looking at Ian, who was holding her. The latter quickly understood, lowered his head, and kissed her—just this small gesture once again made the girl excited. Seeing this, Tohsaka Rin, realizing that if this continued, she'd have to watch them again, quickly spoke up to stop them.
"That's enough!"
"I get it! Sakura, you don't need to demonstrate anymore—I don't want to get sprayed all over my face again!"
Perhaps Tohsaka Rin's words had an effect, or perhaps Tohsaka Sakura truly felt it should end there. She quickly ended her passionate kiss with Ian and signaled for him to put her down. After tidying her clothes, Tohsaka Sakura walked to her sister.
"Sister, thank you. Thank you for finding such a suitable place for Mr. Ian and me."
"It's nothing." Tohsaka Rin felt a little embarrassed—she felt that providing a venue for her sister and Servant to engage in intimate contact was a bit strange. Of course. It was only "a bit." Her heart didn't object to Tohsaka Sakura and Ian doing this—after all, it aligned with their mother's initial intention.
"We're sisters, after all," Tohsaka Rin shrugged. "You don't need to be so formal with me."
However, Tohsaka Sakura, upon hearing this, shook her head. "Sister. That being said—you really did help me a great deal. A necessary repayment is still in order."
"You really don't have to!" Tohsaka Rin waved her hand, refusing. "What's there to repay!"
"Of course there is!" Tohsaka Sakura took Tohsaka Rin's hand. Her face flushed, she clearly hadn't fully recovered from her passionate time with Ian. "Sister's actions mean a lot to me."
"..." Feeling her sister's inexplicable stubbornness on this matter, Tohsaka Rin, unable to argue, had to concede slightly. "Alright. I understand. Then—" Tohsaka Rin put her hands on her hips. "Sakura, how do you plan to repay me? My demands are quite high, you know."
"It's fine," Tohsaka Sakura smiled slightly. "I have a method that will absolutely satisfy you, Sister."
"Oh?" Tohsaka Rin's interest was piqued now. "Then I'll have to see what you've prepared, Sakura."
"It's simple." Tohsaka Sakura leaned into her sister's ear again, whispering her "repayment": "Sister. Would you like to do it with Mr. Ian here once?"
"..." Tohsaka Rin froze, and only after confirming she hadn't misheard did she dare to respond. "Sakura, what kind of joke are you playing?"
"I'm not joking," Tohsaka Sakura maintained her smile. "Sister. You already had Mr. Ian help you [pleasuring] yourself once before, didn't you?"
"..." Tohsaka Rin's eyes widened. She realized that her younger sister knew far more than she had imagined. And indeed, that was the truth. Tohsaka Sakura was a very light sleeper, and Tohsaka Rin's movements that day had been very noticeable. But because she was her older sister, and she had indeed helped a great deal that day, Tohsaka Sakura chose to turn a blind eye.
However, now—she, already somewhat corrupted, once again used that past event.
"Sister, are you unwilling?" Tohsaka Sakura leaned closer. "Mr. Ian is very amazing, you know~"
"..." Tohsaka Rin was silent for a moment, then quietly responded. "Can I really?" The sexually charged scene between the two earlier had indeed excited her—this was the same old problem as before.
"Of course," Tohsaka Sakura said with a smile. "As long as Mr. Ian agrees, you can do it with him." Tohsaka Sakura naturally had her own intentions. There was no way she would simply allow Ian and her sister to have relations. Her current goal was simply to further test the effect of the Command Spell. If there was no mistake—her sister should be rejected on the spot. If that happened, the test would be a complete success.
[And indeed, that's how things unfolded.]
[Following Tohsaka Sakura's instructions, Tohsaka Rin proposed doing that with you.]
[For her—you had already demonstrated your powerful side as Saber, and also your excellent attractiveness as a man.]
[So whether it was out of a final remembrance for the Saber class, or out of infatuation with the opposite sex.]
[Tohsaka Rin was willing to take another step.]
[After all—her sister looked truly comfortable when she was having relations with you.]
[Perhaps she could also feel something.]
However—facing the girl's request, Ian, as Saber, unhesitatingly refused her. "I'm sorry, I cannot do that. I... only wish to do such things with my Master."
At these words, Tohsaka Rin froze. And Tohsaka Sakura secretly breathed a sigh of relief—she had completely confirmed that Ian would indeed not have sexual desire for other girls.
"Um."
"It seems Mr. Ian isn't very willing."
Tohsaka Sakura took the man's hand and leaned her head on his shoulder. "Sister, I'll find another way to make it up to you, okay?"
"No, you don't have to." Tohsaka Rin, rejected by Ian, felt a little embarrassed. She handed the rooftop key to her sister. "If you two want to, just keep going. Remember to lock the door later... I have some things to do, so I'll be leaving first."
"Okay~" Tohsaka Sakura, in high spirits, didn't try to keep her "experimental" sister. "I understand."
Inside the school building.
Tohsaka Rin, descending the stairs, clutched her forehead—she never expected to be rejected by Ian. But whether it was psychological or if there was something genuinely amiss, the girl felt that Saber was now a little off, with many subtle differences from before. What exactly was it?
But Tohsaka Rin didn't have much time to ponder this question—because today was very important. Tonight, Fuyuki City will witness a meteor shower. At that time, the magical energy wavelength of the ley lines in the city will reach its most compatible state with herself! Tohsaka Rin decided that at that moment, she will summon the Servant she will use for this Holy Grail War!
