There are some things you never expect to experience in your life, so you're not mentally prepared for them. One of those things was to be standing on the ground in the middle of the living room, with two absolutely gargantuan white sneakers standing on either side of him like, ironically, foothills of a large mountain range.

Another effect of his position was that Lio smelled an interesting… scent washing over the area. It was weird, he knew Ava took great care of herself, could smell she showered in the morning, but he never thought it would be somewhat… pleasant as a Micro. She probably did, she knew way too much about Micro physiology for someone who would always  be "huge". No, it didn't matter she literally held a degree in physiotherapy with an unusual focus on Micros. Well, that's what he told himself anyway, made him feel better about himself.

By-the-by, there was absolutely no good reason for Ava to have fetched her shoes. She had set Lio down on the floor, smiling down at him when standing back up to her magnificent full height. Then, she just left, and when she returned, she was holding her sneakers in her hands with the most devious smile he had ever seen her with (and she was still smiling like that right now). She had gently set them down on either side of him, but they still shook the earth. He didn’t need a test to find out he wouldn’t be safe underneath those rubber soles.

 
And that’s how the pair came into their current positions. As for Lio’s conclusion on Ava’s reasoning with the sneakers: she did it because it amused her and didn’t harm him. So basically, business as usual.

“Sooo, are you gonna explain what your plan is or are you just gonna be standing there grinning like an idiot?” Lio said, breaking the silence. Not that it was totally silent for him, the slightest twitch in the appendages before him made plenty of noticeable sound. He wondered if Ava could hear it too, given her enhanced senses. If she did, she didn’t show it.

“Tsk, can’t even enjoy myself anymore now? I like being big, and you like looking up at mountain-sized ladies. So why shouldn’t we take a moment to enjoy the view? Besides, you saw Rachel from this perspective when you went Micro. And as much as I like being big, I’ll admit I will never be as tall as your sister, I am curvier though, that’s something.~” Ava replied, putting her hands on her hips and looking very proud of herself. She could have leaned forwards to look at Lio more comfortably, but didn’t, because she clearly wanted to be her “full” height.

“You do realise I’m small, right? That you’re not big? Last time I checked, you have been 175 centimetres since you were 15.” 

Ava just rolled her eyes, her smile fading into a slightly annoyed look. It would have been unsettling if Lio didn’t know Ava as well as he did.

“Of course I know that. But it’s a technique to make Micros feel less, well, tiny. If I refer to myself as “big” or “giant” or “massive”, it makes me the unusual one. That way, the Micro patient can feel more normal, which is really important to some. But alright, good to know it’s not that needed on you.”

“You’re still gonna refer to yourself and Rachel as “gigantic” around me, aren’t you?”

“One-nil for the Micro.”

“And you’re gonna do it simply because it’s also fun for you, isn’t it? You wouldn’t mind actually being huge in a small world?”

“Two-nll, but that stays between us two, got it?“

“Yes ma’am. And one last question, you’re trying to distract my mind from the fact you’re about to plop your socked size nine-and-a-half onto my “puny” 0.85 millimetre form, aren’t you? Probably the left one?”

Ava’s wide grin returned, the sparkle in her eyes visible even over three “kilometres” away. 
“Guess it didn’t work as intended. Maybe you’re more clever than I ever gave you credit for. Oh well, guess we got off on the wrong foot, now’s time for the right one.~”

Lio would have groaned at how lame that pun was, if it weren’t for the roughly 520 metre long, 180 metre wide, sock-clad right foot lifting into the air as Ava raised her knee a little. Lio never thought Ava’s feet were “dainty” or anything, they were roughly the same size as his had been. But even though they were nothing compared to his sister’s “behemoths”, there was an instinctual fear at something so gigantic moving in the air. No, not fear, he felt no real fear around Ava…. It was awe. He looked as the huge foot soared through the air like the world's largest aircraft, only much much bigger. In fact, the closest analogy he had would be sci-fi cruisers flying in low atmosphere. Like before, with Ava’s finger, Lio decided to lay down on his back already…. He’d rather lay down softly than be knocked down “mercilessly”. When he did that, and looked up, he saw Ava wiggle her socked toes in anticipation. Did, did she hear him lay down? There was no way her hearing was that good, right? Maybe, maybe not. Perhaps Ava was just a little too excited about having her buddy underfoot. 

Lio wasn’t sure which option was worse at this point.

He also wasn’t sure whether to be happy or concerned when Ava’s toes passed overhead, an indication she wasn’t planning on smushing him beneath them. And sure enough, the foot stopped when he found himself looking up right at the ball of Ava’s foot. He knew what he was looking at, despite the foot being a dark void of fabric, because the ball, the heel and the toes were more worn out than the rest. For that is where a person applies pressure, those points carry someone’s weight, literally. He noted that Ava was moving uncharacteristically slow, which he greatly appreciated. He also knew it had several reasons. One, to make sure he wasn’t hurt somehow. Two, to make him watch and appreciate the view (even if it was just a foot). Three, to make absolutely sure he would be precisely where she wanted him.

And then the sky dropped. 

The field of black fabric came closer and closer, like a meteor in disaster movies. The closer it came, the more clearly Lio could see individual threads of fabric. The fact that even the threads were large served as a reminder that Ava wasn’t big, he was just incredibly tiny in a much larger world. Another thing that increased was the scent that came from Ava’s feet. It became more potent, more “penetrating”. It was no longer a background feature, it was being blasted into his nose whether he wanted to or not. But again, it was weirdly pleasant. Like entering a flower-shop except the smell was a mix of Ava’s natural odour, showersoap and light sweat. But all of that became secondary when Ava’s socked foot finally touched down on the floor, and pinned Lio beneath it. 

It was so, so much more powerful than Ava’s finger had been. Yes, the weight was more spread out due to the size of her foot compared to her fingertip. But that didn’t matter when the force, her weight, was exponentially higher. And he could tell Ava was barely putting any weight on it, for now. But with every passing moment, the pressure increased as the brunette titaness shifted her balance to be more evenly distributed. Just like before, Lio was able to withstand the force that, logically speaking, should have made him pop like a grape. In Lio’s opinion, Ava’s fingertip had been more comfortable. It had been softer, more akin to a warm embrace. The fabric of Ava’s sock wasn’t particularly unpleasant or rough, but there was simply no beating her skin. It wasn’t moist either, which had been a silent fear of his. He knew it was only a matter of time before his gigantic friend would get to him after a jog or workout, but he would deal with that predicament when it occurred. Another thing that made Ava’s socked foot more annoying than her fingertip: those threads were trying to entangle him like vines in a jungle. The fabric shifted constantly as the pressure increased. Perhaps a normal person wouldn’t think anything of these near-millimetre shifts, but to Lio they were moving entire body-lengths.

Back in the outside world, Ava was rather excited. There wasn’t really a logical reason to enjoy having Lio underfoot, but she couldn’t help it. It was also simply reassuring to feel just how durable her nigh-microscopic friend was. If he could withstand this, she wouldn’t have to worry about his physical wellbeing during their future “fun”. She would also be able to tell Rachel that she didn’t need to worry either, and that she could safely introduce his new “chores”. As for the effects on his mental well-being… she would track those rather intensely, making sure he wasn’t slowly losing it. Ava knew about Micros who didn’t get the right treatment, and the results were widely varied, but all rather concerning from a “healthy” perspective. Some turned inwards and never spoke again, others started seeing normal-sized people as literal gods, or they were treated like pets and acted like ones. The second “possibility” was luckily rather rare with first-generation Micros, but it was a lot more common with second or third-generation Micros: the offspring of a Micro couple, aka those that were never “normal”. Ava had never met a Micro that was that far “gone”, and she hoped she never would. She hoped she could prevent it from happening to any Micro she ever came across, because there was no known case about such a thing being reversed. When the brunette finished her thoughts, she realised she was standing on one leg, the other raised by simply bending her knee. She was worried for a second, but then she felt the faint struggling beneath her foot, and giggled. 

“Well, seems you are as durable as one can get. Let’s get you out of there, hmm?”

By the time Lio heard Ava’s voice rumble, the sock-threads had won the battle. He wasn’t fully entombed in the middle of the sock’s fabric, but his wrists and ankles were “shackled” by the huge black ropes. He felt the pressure lift as Ava raised her right foot. A tremor shook him to his very core as that foot scooted backwards and touched down on the top of her scrunched toes. No pressure was on him, but he was very much tied to the enormous footwear and, well, the foot itself.

“Wait, where did you go?” Ava asked in confusion. She didn’t see the speck she expected on the floor, and it made her worry. But given she also didn’t see any mark of… damage (which she would never forgive herself for), she realised where her Micro-Buddy had to be. And she found it to be absolutely hilarious: “No way.~”

Ava slid her right leg on the tops of her toes so it was in front of her torso. Then, the leg lifted and bent at the knee. The brunette grabbed it at the ankle to keep it steady, and to look at the sole of her foot. She did all of this without wobbling even a little, her balance was immaculate. She dabbled in light yoga as part of keeping healthy. And sure enough, she found Lio stuck to the ball of her foot, unable to do anything but struggle and look up at the ridiculously amused face of his gigantic best friend.

“Stuck to me like a piece of dust. Oh how fitting considering how often I dragged you along to certain places and people.”

“Yeah yeah, I get it, you find this hilarious. Just get me out of here. And you better hold your end of the bargain whenever I ask for it!”

“Of course, that’s what friends are for. Now c’mere little buddy, let’s get you off of my mean huge foot.~”

As Lio saw Ava’s fingers coming towards him once more, he found himself realising a large part of rest of his life would indeed be spent clinging to the bodies of titanesses.
