Shirou thinks seriously about his decision, before eventually saying “I think I’ll just need to depend on you, Rin. I don’t think I’ll be able to provide for Saber in the long run while I’m stuck like this...”

Upon hearing that, Rin grins and says “Perfect!” Then Rin makes the preparations to transfer Saber to become her servant, instead of Shirou’s. She grabs a piece of magic parchment and writes a contract stating that she would assume command of Saber as long as Shirou was shrunken. She also includes a clause stating that she would keep Shirou safe until he recovered.

Once it was ready, both Rin and Shirou sign it, immediately affecting them with the powerful magic.

And once it was finished, Rin says “All done! How do you both feel?”

Shirou stretches and says “I feel like I have a lot more energy. I didn’t realize how tiring supporting a normally sized servant could be at my state.”

Saber nods and says “I feel a bit better as well. Thank you, Rin.”

Then Rin says “Good! Saber, why don’t you take a nap for now? You must be exhausted, after running on such a small supply of mana.”

But Saber replies, saying “No, I’m alright Rin. You don’t need to worry…” But Saber loudly yawned in the middle of her sentence, and a small tear formed in her right eye, so she said: “Maybe you’re right, Rin.”

So Rin smiles and says “I know! Head into the room on the left; there’s an empty bed you can rest in. I’ll keep an eye on Shirou.”

Saber says goodbye to Rin and Shirou, and then she takes her leather boots and goes into the bedroom, before closing the door behind her. Then Rin looks down at Shirou, who was still in her palm, and smirks before saying “Well then Shirou, I’ve gotta wonder, how did Saber bring you over here?”

Shirou starts to blush, before eventually saying “Well... She thought I’d be mostly hidden if I... went in her boot...”

Rin merely looks at Shirou as if he didn’t say anything odd at all, but then her eyes suddenly widen as she fully processes his statement. And once she does, Rin says “She did what?? How’d you even make it here intact? You’re barely bigger than a bug Shirou!!”

Shirou sighs in response, and says “You don’t need to remind me Rin...” She giggles at his annoyance, so he continues, saying “And I felt pretty okay while in Saber’s boot. I wasn’t in pain or anything and it was kinda nice...”

Hearing this, Rin leans a bit closer and eyes her tiny friend suspiciously, while saying “And what does that mean...?”

Shirou quickly waves his hands in the air erratically, while saying “Ignore that Rin! I spoke without thinking! I just had a stressful day...”

Rin smirks and places one of her socked feet next to him on the table while saying “I think I’ve got you all figured out, Shirou...” He watches nervously, as her massive foot rested next to him, reminding him just how small he was. And the smell was intense, but not in a bad way, although he tried to keep his composure since Rin seemed to be watching him closely. But then she continues, saying “I’m a smart girl, Shirou. You’ve got a thing for feet, don’t you? There’s no need to hide it because I just thought of how you’ll earn your keep!”

Hearing this, Shirou scratches his head, not as concerned as he thought he would at this since Rin seemed too casual about it, and says “What do you need me to do for you? I can’t exactly cook anymore at this size, and I can’t think of any kind of housekeeping chores I could do...”

After that, Rin giggles before saying “I’ve got a lot of homework to catch up on since I was neglecting it for the grail war. But honestly, I just wasn’t motivated, but now I’ve got a great motivator!”

Shirou, still unaware of what Rin wanted from him, asks “And how will I motivate you?”

Rin sighs and mumbles “How dense can he get...” But she quickly clears her throat and says “I want you to give me a detailed foot massage! You’re small enough to fit into some pretty tight spaces, and my feet are super sore, so you’re gonna be busy!”

Shirou just scratches his neck and says “How will giving you a foot massage make you more motivated to do homework?”

In response, Rin grumbles while rubbing her temples, before saying “Just stop questioning it and do it! You like feet and I’m a highly attractive girl, so just stop being stupid and say okay! Need I remind you who is keeping you safe now...?”

Shirou starts to nod quickly while saying “Okay! I’ll do whatever you need!”

Following that, Rin carefully picks him up and brings him into the study where her school work was prepared. And once they were there, she places him on the floor before starting to remove her black thigh-high socks, providing the tiny master quite the show. She made sure to do this both slowly and deliberately, apparently in an attempt to fluster her friend, as she gradually revealed more and more of her bare leg.

Once she got down to her ankle, she started to roll the sock off the rest of the way, revealing to Shirou that her feet were slightly sweaty from being stuck inside those stuffy socks. Shirou quickly started to imagine what it might feel like to be trapped in those socks, making him want to ask Rin about that later, but his thoughts were cut off when she suddenly tosses the rolled up sock in his direction.

As this happens, she laughs and says “Better dodge out the way, Shirou...” Luckily, the bunched up sock missed him, but he didn’t have long to rest when the other one rolled toward him. Shirou managed to dodge that one too, causing Rin to quietly clap and say “You’re one entertaining bug, Shirou! Ready to get to work?”

Shirou nods, so she plants both of her now bare feet in front of him, showing off her dark red toenail polish. And now that her right foot was mere inches away from him, the powerful unleashed odor washed over him, filling his senses. Even at this extreme level, the smell was enjoyable for Shirou, causing him to watch closely as she playfully wiggled her toes. As she does this, she says “It does feel nice to take off your socks! I’m looking forward to what my buggy Shirou will do for me...”

Hearing this, Shirou advances toward Rin’s impossibly giant toes, ready to get to work...

First, Shirou walks up to Rin’s big toe and begins to press his hands into it. He was utterly amazed by how soft it felt, and the light amount of sweat only really made it difficult to get a good grip on it. But then he starts to rub that toe forcefully, hoping that Rin would notice his efforts, although she didn’t react to this. After a minute or so of trying, Rin taps her foot, nearly crushing him under it while saying “Not sure what you’re trying; but it’s not working! Either try harder or do something else...”

Listening to her advice, Shirou tries to ram his whole body into her toe, almost as if trying to tackle someone. Nearly immediately, Rin starts to giggle and say “This is a good start! Keep up the effort!” Shirou spends few minutes on that toe, before realizing that he might have an easier time with Rin’s other toes, so he moves along.

When he reaches her 2nd toe, he starts to massage it, pressing his hands vigorously into the soft and warm flesh. With this one, he didn’t need to massage as intensely as before, which was a relief. As he rubbed, he noticed that his hands were getting coated in sweat, and occasionally large globs of the salty stuff would drip down the toe and burst right onto him. Shirou doesn’t let that slow him down, even though the taste was incredibly intense, so he continues to rub hard. While he was working, he hears Rin grumble and say “Why do they need to assign so much busy work...? So annoying!”

Right after saying this, Rin slides her foot ever so slightly forward, running him over with her 2nd toe in the process. And as he struggled to free himself from underneath that mound of sweaty flesh, she starts to press her toes into the ball of her foot, while muttering “Got an itch all of a sudden...” Because of this, Shirou was regularly smashed between those two beasts of flesh, without even a chance to escape. Somehow though, being so thoroughly dominated by Rin’s foot, while she wasn’t even trying, was strangely exciting for him.

This lasts a little while until Rin stopped bothering him, leaving him to realize that he was practically glued to the ball of her right foot from her sticky sweat. And no matter what he did, he couldn’t free himself, until she lifted that foot into the air. Shirou watched nervously as she lazily lowered her right foot on top of her left one, without a chance of altering Rin of his current position. And after that, she began to scratch that sole against the top of the left foot, leaving Shirou to wince as the sounds of flesh scraping deafened him.

After a few intense seconds of this, Rin lazily wiggles her toes, causing just enough movement in the ball of her foot for Shirou to come loose. Unfortunately for him, he landed right into the space between her 3rd and 4th toes on her left foot, leaving him trapped in this vice of sweaty flesh. While trying to free himself, he was only met with annoyance by Rin, as she squeezes her toes in response, absolutely smothering him.

While doing this, she mumbles and says “Did something land between my toes…?” As she ponders this, she starts to lazily shuffle him between her toes, effortlessly man-handling him in the process. This also caused Shirou to be shoved deeply into each of her sweaty and dirty toe spaces, allowing him to even see the bits of black sock cotton that were stuck between them. After a bit of this though, Rin taps her chin before saying “Wait... I think I know what’s going on…”

She then starts to giggle and say “I must have lost track of you! Still having fun?” Shirou would respond he could, but since she wouldn’t hear him right now anyway, he doesn’t bother. Rin realizes this too, so she just laughs even harder and says “Well, you feel pretty good to play around with... And you were doing a pretty good job...” But then she suddenly grins down at Shirou, making sure that he could see her, as she says “Now that you’re here, why don’t you show me that you find my toes amazing? I’m sure you can kiss them, right Shirou?”

Shirou was curious about what this might feel like, so he presses his lips against the side of her 2nd toe, giving it a soft kiss. Even by allowing his lips to touch her toe was enough to fill his taste buds with an extremely salty and sweaty flavor, causing her to giggle and say “That tickled! Why don’t you go a bit deeper...?” Shirou listens to Rin’s request, and this time burrows down lower between her toes, and plants another kiss in the tight and cramped space between them.

As he does this, Rin squeezes her toes again, totally enveloping Shirou in the warm and sweaty flesh, as she says “You’re so diligent Shirou! You also gave me a great distraction while I did my homework!” Rin starts to stretch after saying this, squeezing her toe even harder in the process, brutally smothering him. And after doing this, she stands up and says “As a reward for being such a great massager, I think I’ll let you stay where you are while I do my afternoon workout!”

She doesn’t even ask for the opinion of her tiny friend, as Shirou wonders if this was a wise idea since he’d be in for a genuinely rough experience if he remained where he was. But as she thoughtlessly walked toward her bedroom, rattling his brain with each bounding step, Shirou also thought that this could be highly exciting.

Shirou decides to just look forward to the experience, while Rin enters her room to change and prepare for an afternoon workout...
