Ian frowned slightly, looking at the message on the screen. Although Ritsuka Fujimaru had "dueled" with Mash several times, this was the first time she had asked him to help her cheat. Out of curiosity, and also out of caution, Ian decided to ask for more clarification.
[Ritsuka, it's possible.]
[But you need to tell me why you want to do this.]
The man sent the message and quickly received a reply from her.
[Can it be a secret for now?]
[I'll tell you why later.]
"..." Looking at the screen, Ian knew he shouldn't press further. Every girl in Chaldea was allowed to have secrets. He wasn't there to make them transparent and open books.
[Understood.]
[Then... how about tomorrow?]
[Yeah, I knew you were the best~]
Even without hearing Ritsuka Fujimaru's voice, looking at the message, Ian could still feel the uncontainable joy in his savior partner's heart. Thinking of this, the man looked at Olga Marie beside him. She was still sleeping soundly—she seemed completely accustomed to being restrained in her current state. Ian said nothing more, simply taking off his clothes and covering her where needed.
BB's Morning Lesson
The next day. Remembering his promise to Ritsuka Fujimaru, Ian woke up very early. Perhaps they had played too wildly. Olga Marie was still immersed in sweet dreams. However, Ian wasn't worried—after all, sleeping soundly was a rare and precious experience in itself. Moreover, seeing her like this, the man felt much more at ease.
After a moment of thought, he took out his phone and called out. "BB, are you there?" The man wasn't just calling out randomly. As a Super AI who came in response to Sakura Tohsaka's wish, BB could freely move through any place where "data" existed. This included computers, surveillance cameras in Chaldea, even Ian's phone, and the body created using Da Vinci's Noble Phantasm. As long as there wasn't an overly powerful defense like before, BB could come and go as she pleased. And as his personal Super AI, BB, whose affection level was already super high, immediately responded upon hearing his call.
"Pig, why are you calling me?"
Seeing BB respond, Ian immediately asked, "BB, since you can operate in virtual space, then—can you control ○-vibrators?"
"..." BB froze for a moment, then shouted, "Hey! What do you take BB for, you pig?! BB is a Super AI—how could I go inside something like that?!"
"So... you can indeed go inside and control it?"
"..."
"Of course I can," BB mumbled, incredibly embarrassed. "A so-called ○-vibrator is essentially just a tool that runs according to a program. For something so low-level, no matter how many there are, BB can control them like toys. But being able to do it doesn't mean BB wants to! Why do you want BB to go into a place like that?!"
"Because—" Ian looked at Olga Marie, who was lying on the chair nearby and had temporarily "become" a part of it, a slight smile on his face. "I want the Director to continue enjoying that pleasure. Yesterday, when she was thoroughly explored... she was absolutely thrilled."
"..." BB was silent for a while before replying again. "Olga Marie wasn't happy because she was explored—she was happy because she could vent her sexual desires for you, right? How did you even do that?! Even though it's such a wild and embarrassing game... they're all still willing to try it with you. BB completely can't understand it."
"If you can't understand it, then don't think about it," Ian said, looking at the Super AI on his phone screen. "After all, didn't you, BB, also willingly let me take you to bed?" The man's words immediately hit BB's weak spot. She blushed and explained, "BB's situation is different, okay—! I only used my body to obtain data for the devil's game!"
"Alright, alright, whatever you say," Ian smiled slightly. "So, BB, are you willing to help me with this favor?"
"..." The BB on the screen turned her face away and mumbled softly, "At this point... BB, of course, has to fulfill your wish—you are BB's Master."
"That's great, I knew you were my good BB," Ian praised her without hesitation.
"Oh, right—!" the girl said, as if remembering something. "BB discovered some strange things again last night."
"Oh?" the man was quite interested. "What is it?" He hadn't forgotten that he had spent all of last night trying to get more information about the former Director from the office computer, but to no avail.
"Hmm..." The girl on the screen rested her chin in her hand, appearing to be deep in thought. "BB remembers you saying—that it's now a world after the incineration of humanity, and apart from Chaldea, humanity is practically extinct, right?"
"..." Hearing BB say this, Ian recalled the sky full of fire he had dreamed of when he returned to Chaldea from Singularity F. Yes. This world had been completely incinerated by humanity. Chaldea was the last remaining hope.
"Mm," the man nodded. "You're right—that's indeed the situation now."
"Then that's very strange!" BB put her hands on her hips, looking very puzzled. "When BB was investigating yesterday, I discovered some mysterious signals."
"Mysterious signals?" This time it was Ian's turn to be confused. "What are those?"
"Hmm... BB doesn't know either," the girl rested her chin, as if trying to recall something. "But BB can feel the existence of that thing; it's very similar to a 'blog.' But—its signal is very unstable, as if it could disappear at any moment. Master, do you think I should keep investigating?"
"Isn't that obvious?" Ian replied without thinking. "Such signals shouldn't appear at all... this might play a role in resisting the incineration of humanity. BB, investigate it thoroughly!"
"What kind of tone is that, you pig!" BB pouted. "But I'll let you off this time—seeing as you called me 'good BB' just now."
"Oh, so you like that address, do you?"
"No way—!" BB licked her lips. "BB just purely feels it makes me a bit closer to you, you pig."
"..."
"Hehe," Ian laughed. "I can't help it—this kind of BB is really to my liking. Next time, I'll definitely make you call me 'Master' in bed."
"You can say that when you can clear LV3 of the devil's game, you pig!"
After some playful banter, Ian entrusted BB with the task of keeping Olga Marie ○-ing. For the next while, she would continuously make the Director recall her most wonderful experiences in his stead. Thus, Ian, now free, quickly sent a message to Ritsuka Fujimaru.
[Ritsuka.]
[Can I come over now?]
Not long after sending the message, he received a reply from Ritsuka Fujimaru—it seemed she had also woken up very early.
[Mm, come.]
[Mash and I are waiting for you in Room 048.]
Each Master candidate in Chaldea was assigned a multi-functional room. As Master No. 48, Ritsuka Fujimaru was naturally no exception—in other words, this was her room. However, after forming a practical contract with Mash, this place became their shared residence. Of course, Mash would sometimes go to Modred's room for a while, fulfilling her responsibility to take care of her for Ian.
Soon, Ian arrived.
[Ritsuka, I'm here.]
Less than five seconds after the message was sent, the door to Room 048 opened. But it wasn't Ritsuka Fujimaru who came to greet Ian; it was Mash. At this moment, she was only wearing a thin nightgown, her shapely figure fully revealed, inviting various fantasies. Seeing Ian, Mash's cheeks immediately flushed. Having already accepted him as her Master, merely being looked at would make countless embarrassing memories of being "educated" flood her mind.
"Senpai... you're here," Mash said shyly. Ian, however, remained as calm as ever in the face of her shyness. He knew what she was thinking, so he naturally felt no nervousness.
"Mm," the man reached out and stroked Mash's somewhat warm cheek. "I'm here—have you prepared the tools in advance?"
"Yes, yes, we have!" Mash nodded repeatedly. "Ritsuka and I have already prepared the tools—we were just waiting for Senpai to arrive!"
"That's good then." Ian's hand playfully weighed Mash's breast. "Let me in."
"Mm~" Mash lowered her head and stepped aside, making way.
A New Kind of Competition
Entering the room, Ritsuka Fujimaru was already sitting on the bed, seemingly ready. She glanced at Ian, a hint of calculation in her beautiful orange eyes. Clearly, this Master No. 48, who had proactively studied healing Magecraft, was asking the man if he still remembered last night's promise. Ian, of course, remembered. Even though he didn't know what Ritsuka Fujimaru wanted to do, since she had such a request, he would definitely help her without harming Mash.
Mash didn't notice Ian and her Master's exchanged glances. She just felt very happy—because he had come. Taking Ian's hand, Mash sat down on the bed with him, the two cute girls leaning against the man on either side.
"Senpai," the pink-haired girl whispered. "Ritsuka said... we're going to 'compete' again today, right?"
"Yes," Ian nodded, not denying the fact. "Then—" Mash's purple eyes showed a hint of anticipation. "Senpai... what kind of competition do you plan for us today?"
"..." Looking at the expectant Mash and the thoughtful Ritsuka Fujimaru, Ian pondered for a moment and then directly replied, "Hmm... since it's already been several times—let's try something new today, shall we?"
"N-new?" Mash's throat constricted slightly.
"Yes," the man nodded. "Let's change the way we train ○-climax endurance—let me see if your skills have improved."
"I understand!" Mash looked at Ritsuka Fujimaru beside her, clearly asking for her opinion. "Then, Ritsuka, you—"
"No problem," Ritsuka Fujimaru smiled faintly. "I love competing with Mash."
The Two-Pronged Attack
Ten minutes later. Ian had finished preparing for the competition. On the table in front of him, Ritsuka Fujimaru and Mash were bound together, one above the other, in an "X" shape. However—the direction of their "X" was reversed. Ritsuka Fujimaru's hands were tied to Mash's legs with their underwear, and her legs were, in turn, tied to Mash's hands. In this state, what appeared before their eyes was each other's private gardens, which they could touch with just a slight extension of their tongues.
"The rules are simple—each person just needs to last half an hour without ○-climaxing." Ian explained. "Mash, you start, okay?"
"Y-yes, I can," Mash said, nodding obediently even though she couldn't see Ian. But what she didn't know was that behind her, Ritsuka Fujimaru had already reached a temporary agreement with Ian—they were definitely going to make Mash unable to hold on.
"Then let's start now." Ian put the ○-ball in Mash's mouth and returned to the other side. After exchanging glances with Ritsuka Fujimaru, the man immediately began attacking Mash's weak points. Generally, if it were just this process, it would be easy to accept—after all, Mash's level of development was already far beyond simple penetration. However, the pink-haired girl didn't expect that this competition also had a special hidden rule. That was that Ritsuka Fujimaru could also use her mouth!
While Mash, who was below, was being freely entered and exited by Ian, Ritsuka Fujimaru, who was above, also extended her tongue, gently licking the point of their intersection, and finally even joining in directly, beginning to suck. The man also intentionally sped up, making Mash even more sensitive. This was an absolute two-pronged attack!
Soon, Mash couldn't hold on any longer; her body began to tremble—she wanted to say the rules were unfair, but with the ○-ball in her mouth, she could only make muffled sounds. Finally, she couldn't endure it—with a tilt of her head, Mash collapsed limply onto her Master's body.
She won. Ritsuka Fujimaru, drenched by Mash, looked quite pleased. She gazed at the man's ○-stick, which was standing against her face but ending inside Mash, a happy expression on her face. "Ian... you really did help me."
"You said so yourself... how could I not help you?" the man said, pulling out his weapon and placing it on Ritsuka Fujimaru's face, gently rubbing it. "So, Ritsuka, what do you really want to do—just win against Mash once?"
"No way!" Ritsuka Fujimaru shook her head. "Of course I have a reason for doing this."
"A reason?"
"Mm!" Ritsuka Fujimaru licked her lips. "Ian. I... want to summon one more Servant!"
