As you sit in a balled up lump atop her bra, you cannot help but feel a little saddened by being discarded, even if only temporary. You wanted to hug Kristen's waist for so much longer it was driving you crazy. In fact, you decide to make it so that she never has a reason to remove you.
Thinking of the gun, you adjust the setting and first aim the gun at Kristen, then at yourself and fire. You wait only 20 seconds before the locker is hastily yanked open and Kristen is desperately putting you back on. When she snaps your band around her waist, she let's out a long sigh of relief.
You then feel your form change. If Kristen would be wearing you all the time, then you would need to up your game and responsibilities. As Kristen walks back to the gym, you feel yourself puff out, filling with moisture absorbent material until you are a crinkly diaper, all but glued to her crotch. Your body gains three powers as well, the power to dispose of any and all of Kristen's wastes, the power to keep her clean and fresh, and the power to adapt in size and shape in order to handle any mess she makes in you.
You are all but attached to Kristen now. And as you feel her legs move around, and absorbed all of her sweat. You find yourself loving this idea even more. Especially with how she isn't wearing anything over you. You are glad you changed her to always need you. That dependency will become the core of your everlasting bond together, as diaper and wearer.
As Kristen continues to move around, you notice her pussy is starting to feel a little different as it rubs against you. Then while she takes a quick rest, she begins using you. Nonchalantly, you start to absorb her piss, doing exactly what your job now is. You feel yourself turn warm, and gain a yellow tint in the front. It felt so good.
The immediately afterwards, you begin processing her pee, absorbing it, breaking it down into nothingness until you are all fresh and clean once more by the end of gym class. And as Krysten returns to the locker room, she picks up a miniskirt and drapes it over top of you. However you are big enough to obviously poke out from underneath. So the skirt isn't hiding your existence whatsoever.
It doesn't seem like anyone particularly cares about the diaper clad girl, so you don't pay them any mind at all. You have more important matters to attend to anyways. You think of the gun once again, and shoot Kristen with it. You feel yourself fill out a bit more, as you are sucked between her ballooning ass cheeks and pulled snuggly against her pussy. Even as a diaper, you now appear to be a slightly thicker thong on her body. Her ass pokes out the sides through your leg holes, wedging you deep inside her crevice of an ass crack.
Kristen, now walking with a notable sexy swing in her wider hips, shakes her rounder ass with each step, rubbing you between her ass cheeks as she goes. You are elated with this change, as while she still isn't fat by any means, her hips and ass would definitely land her well within the PAWG range.
Suddenly you feel a hard impact to Kristen's left ass cheek reverberate through you, and a sexy moan escape from Kristen's lips as another girl begins laughing. You recognize the voice as Kristen's best friend Mai, an attractive Japanese girl who had move to the area about 10 years ago. The two of them were best friends since day one it seemed.
It had become a long running joke that the two were lesbians for each other. Only emphasize by how the two of them would then kiss each other to play along with the joke. That said, Mai had had several boyfriends over the years, but none of them ever lasted too long with her. Right now she was single, but still hung out with Kristen almost daily. Mai was not big up top like Kristen was, however she by far had the best ass in class, even now after enhancing Kristen's ass, she was still second to Mai's.
You heard the two of the start talking before they entered what you guessed was the bathroom together. Knowing where Kristen was strangely insulted you. You handled her wastes, so she should never need to step foot inside this room. But that was before you felt Mai's hand slip underneath your straps and start feeling around Kristen's ass. From what you could see, the two were standing right on top of each other in the large stall, and if what it sounded like was true, then they were definitly making out right now.
Reveling in the fact that you were witnessing two of the hottest girls confirm their lesbian relationship, you eagerly did all that you could to observe everything you could. You even gave way for Mai's fingers when they tried moving around to the front side. Watching Kristen get fingered this close was a sight to see, you could literally see inside her pussy as Mai's fingers spread out her lips and stirred around her insides.
You were kinda surprised that Kristen was the submissive one if their relationship, but were quite happy about that point all the same. It meant that you had a front row view of everything.
When Mai had enough, she must have been edging Kristen, because she just toyed with her clit for a moment, then suddenly you were absorbing Kristen's cum. It happened so suddenly that it even caught you by surprise. But as her permanent diaper, you did your job very well, and made sure that not a single drop of it escaped your confines.
Kristen, who was being toyed with, squatted as her legs gave out and sat down on the toilet seat, sandwiching you between her thicc ass and the cool porcelain top. You once again knew that you made the right choice in becoming Kristen's diaper.
Kristen's legs were separated by Mai, who has crouched down between her legs. Mai leaned right up to Kristen's pussy with only you between them. Then Mai gave you a lick. But what made every fiber of the fabric you were made up of shiver, was when Mai softly whispered, in a voice so quiet only you would hear, "let's have a little chat later, diaper."
Your mind raced. How does she know? Why didn't she call you out? Why didn't she do anything but this? What does she want to talk about? Regardless though, Mai somehow knew, and now you had to talk with her later.
