[ABDL, Diaper Use, Soiling, Wetting]

Traversing the stars was a difficult yet wonderous experience. Something that very few people got the chance to do, even now after Humanity managed to pierce through their atmosphere to leave their old home behind. Those that were lucky enough to join up with the Space Messiah Coalition and got carried across the sea of stars thanks to the Mothership were blessed beyond belief, because they didn't just get to explore the universe and see what they might be able to discover. They also had the chance to personally visit these worlds they passed on by, to see if they might be able to colonize these worlds...

But it wasn't all sunshine and rainbows. Especially not for those that served as the vanguard that needed to confirm if the planets they visited were actually safe to explore. This was the case for one young blonde dark-skinned lady, who was currently sitting in the transport that would bring her back to the Mothership.

Her name was Valentine. A Buster that was rising through the ranks of the SMC very quickly, thanks to how proficient she was with the blades that they had at their disposal. It didn't matter if she was facing against some big monster, or violent natives that didn't take kindly to them touching down. She'd defend her friends and her extended family, all for the sake of their mission.

Valentine's status as a Buster meant that swinging her blade for the sake of others was the most important duty that she could carry out. But unlike the long-ranged Blasters, she had to be up-close and personal at all times. Which had more side effects than she'd like, one of them resulting in the heavy weight around her waist and her current exhausted state.

She wasn't one to be spooked by monsters. But when that massive thing with so many eyes and mouths started to roar at her, she lost her cool completely as she sliced it in twain. All while her diaper, the high-duty variant that every Buster and Blaster wore as part of their regular equipment to make them stand out amongst their fellow diaperbutts, was filled to the brim with the filthy mess that she couldn't stop pushing into it.

Of course, she probably shouldn't have been on this mission in the first place. But since she hadn't yet been paired up on a team, so she just had to take on solo missions regardless if they were fit for her. All so she didn't have to worry about people seeing her. Because despite the fact she appreciated her diaper a lot and loved how it kept her from making an even worse mess compared to when she still wore panties, she didn't want anybody to notice and tease her over it.

"Little Valentine..."

Valentine's eyes widened as she suddenly shot out of her seat, snapping to attention and saluting as a hologram started to form inside the transport ship. A maternal hologram that she was very familiar with. A hologram depicting the one that had given her the chance to make herself useful, and blessed her with this cute diaper that kept her nice and 'clean'...

"M-Mama Messiah!" Valentine cried out as she saluted. "M-Mission accomplished! I-I've secured a place for us to stay on-" She tried to report her mission, only for her body to tremble as she spoke. Not now, she didn't want to make another mess when she had just done such a good job! She didn't want to embarrass herself like this, no no no!

But she knew that it was okay. because Mama Messiah was here for her. She was allowed to make messies and stinkies in her presence. She was one of the few people that she could trust not to tease her. So much so that the dark-skinned girl quietly squatted down... And let out a potent sigh of relief as the back of her nappy started to stretch out further, making it even harder to hide under her outfit. At least the only one that could see her was her beloved Mama Messiah...

Messiah giggled, the hologram flickering as it showed off her matured and maternal form. She barely wore anything, at least that's what it looked like with how tight the fabric clung to her body. And you never truly focused on anything besides her breasts and her hips, because her hair filled with stars was far too encompassing and engrossing. Even when she was but a hologram that couldn't capture her true beauty.

"That's my little Valentine. Such a good Buster Baby." Messiah said as she reached out and carefully patted the youthful girl on the head. And even though she wasn't able to make proper contact with her head, the young girl could feel the affection radiating off the hologram, achieving the same sort of effect.

Valentine drooled a little as she felt that hand on her head. It felt really good. It was what made everything worth it. So much so that she absentmindedly started to push a bit more of her poopy into the back of her padding, forcing her to stop squatting and just sit down on the beanbag-sized diaper at this point. She didn't even snap to reality once she felt the sheer size of her diaper, because of the warmth from her Mama. Mama would accept her no matter how big her mess had gotten...

"You deserve a reward for what you've done, Valentine. A big reward. Could you be a dear and meet me in my quarters, once you return to the Mothership? I'm sure that a good little Buster Baby like you could do that. You don't have to worry about what people think of you. Just make sure you make it to me, and Mama will take care of it all." Mama Messiah's words were so engrossing that Valentine was actively blocking out everything around her. Even the announcement that notified her that the transport vessel had almost docked with the Mothership, and that she should get going.

Valentine just nodded as she listened to Mama Messiah, drool actively running down her chin. She had made a mess that was a bit too big for somebody like her, but that just meant that she didn't have to worry when she headed for Mama's quarters. She wouldn't notice everyone teasing her...

Messiah smiled in turn as she knew her little Buster Baby understood what she needed to do. Vanishing, as she waited patiently for her arrival...

---

"My my, look at that! Look at that biiig mess!"

"She's that Buster, right? The one without a team? No wonder she doesn't have one, there's nobody that can match her messes!"

"She's really cute, I wonder if she'll want to try and mess with me?"

"Aha... I wish I had somebody as cute as her on my team. Stinking away without a care in the world.."

"Look, she's messing again! Cuuuuute!"

As Valentine slowly but surely dragged herself through the Mothership to try and get to Mama Messiah's quarters, she could hear people talking about her. She could hear them praising and teasing her about her messies. And while she would've usually blushed and gotten paralyzed to the point where she could hardly keep walking, something was different this time.

Thanks to how much she had already pooped herself before making it back to the Mothership, it was hard for her to muster up the feeling of shame or embarrassment. Why would she feel something like that, when she had a meeting with Mama Messiah to look forward to? If anything, the fact that they all thought she was cute and such a good poopy baby was making her all sorts of fuzzy. She was going to be perfect for Mama..!

As the whispers continued growing in number around the Buster Baby, Valentine let a bit of drool run down her chin once more. All while that already saggy seat just kept on sagging further down. She was on the verge of letting it all burst out at once... If she was wearing a normal SMC diaper. The Buster-brand diapers could handle up to ten times as much, something she was eternally grateful for...

Even though she was actively dragging an exercise ball's worth of poopy around in her diaper, the people that saw her waddling towards Messiah's chambers were just clapping and cheering for her. It was so impressive to see a devoted Buster Baby do her very best to carry out her task. Even if that task was just making it to her Mama.

And as she stepped into the elevator leading up to those quarters, she turned around and faced everyone that was cheering for her. So many of her kin, all of them padded just like her. None were as messy though, even the other Buster Babies only managed to fill theirs down to their knees. She was... She was the very best out of all of them. And while that would've made her so thoroughly ashamed if she had any sensibilities left inside her head...

Right now, Valentine couldn't help herself from giggling with pride. Until the moment her elevator started to move, pulling her higher and higher into the Mothership. All while she could still hear them all cheering for her, congratulating her on a mess well done.

The elevator dinged not long after it had started to move, and the doors opened once more. Revealing a bedroom fit for a matron like Messiah. It wasn't a proper office, far from it. If anything, it looked like the combination between a nursery and a proper mother's bedroom, which would explain why there were several cribs lining the walls and a massive queen's sized bed in the far back.

But there was just one thing that seemed to be wrong about this gentle room. Mama wasn't there. Mama said she'd be waiting for her, so Valentine felt her heart shivering as she stepped out of the elevator. Where was Mama? She thought she'd be here, she said she was going to be here, so why wasn't she there? The dark-skinned girl was struggling to wrap her head around her Mama telling her a lie, so much so that she pinched her thighs together...

"Little Valentine." The sweet and soothing voice of her Mama echoed through her ears, causing Valentine to let out a loud gasp. All while the violent hiss of her bladder letting loose echoed out through Mama's room, the front of the Buster Baby's diaper soaking up all the pee that just poured out as it grew soggy and gained even more weight...

Valentine felt a few tears running down her cheeks as she whipped around and wrapped har arms around her much taller and extra-loving Mama, snuggling her lots and lots. "M-Mama Messiah, I-I-I!" She couldn't really figure out what she needed to say. Just that she wanted to tell the woman how much she cared about her. Even though she was currently messier than she had ever been, and pissier too. And yet despite how much her diaper had been filled, despite the inner state of it, not a single speck of brown had formed on the outside. She was still as 'dry' as she could possibly be...

The adorable Buster Baby was quietly silenced by having Mama Messiah slowly let her hand fall on her head. Ruffling her hair and wrapping one arm around her body, letting her rest up against her big bosom. All while quietly lifting her with that very same arm and carrying her towards the bed in the back of the room. A bed that was perfectly fit for the two of them. Nobody would interrupt them, nobody would stop them from having a bit of intimate fun together.

"You've been such a good little Buster Baby, Valentine..." Messiah said, slowly but surely petting her as she laid the girl down on the bed. All while that massive mess sagged over the edge, a sign of her devotion towards the maternal woman. "I'm so proud of you for everything you've done so far, little Valentine..."

Valentine squirmed as she was laying down on Mama's bed. Not because she disliked it, far from it. She loved every moment of being on the same bed that Mama always slept on. She just didn't know how to properly react. Not that many would, considering the maternal woman's status. Considering that she had arrived to protect Humanity after watching over them from the Moon.

She certainly didn't stop her Mama from grabbing ahold of the waistband of her diaper. Nor did she stop her from snapping off the tapes that kept it securely pinned to her waist. For somebody as strong as Messiah, changing a baby was as easy as breathing. But that didn't mean that she half-assed it. Far from it. She wanted her Babies, every single little Baby aboard the Mothership, to feel like she truly loved them as a Mama would.

With a slip snap of her fingers, the Buster-brand diaper vanished into nothing, consumed by the power of the matron that headed the SMC. And in its place was a brand new diaper. Not another Buster-brand diaper, but a cute pink one decorated in lots and lots of flowers. Because this one wasn't meant to be used during active duty. This was one meant for comfort and comfort alone.

Messiah didn't just get rid of the dirty diaper with nothing but a snap of her fingers. It also cleaned up Valentine's thoroughly dirtied bottom. Not by simply teleporting it all away, but by cleaning it up in a matter of tiny moments. It was so thorough and so tender that even though the matron hardly actually touched Valentine during that moment, she could still feel the sheer pleasure rushing through her as if the older woman had cared for her personally. Rubbing her fingers up against her most intimate areas and wiping away all the filth that had stuck to her after all her intense pooping...

Valentine couldn't help herself as she trembled all over once more, her lips parting to let out an orgasmic cry thanks to what her Mama had done. She could feel the juices pouring out of her lips as she struggled to keep herself holding on. It was so wonderful. She wanted to experience it again, but she knew she couldn't push her luck. She had already gotten such a big reward by being in her dear Mama Messiah's presence. She didn't deserve more.

As Mama tugged ever slightly on her thigh, the young Buster Baby lifted up her legs so it was easier for Mama to reach underneath her. She giggled as she felt the soft and snug padding brushing up against her sensitive and soft butt, while the diaper was woven through her thighs and snapped onto her front just like that. A change at the hands of somebody as powerful as Mama Messiah was quick and simple, and was guaranteed to leave the baby happy...

"There we go. Now we can have as much fun as you'd like, my little Valentine." Messiah chimed as she slowly laid down on the bed, right beside her comfortably padded Baby. "You've done such a good job that I'll do anything you want. Just say the word, and it'll be yours." She chimed, and given what she had already done for her as well as the rest of the Human race, it was hard to think that she wouldn't be able to fulfill her wants and needs.

Valentine tried really hard to think of something that was worth asking her Mama about. She could ask for a lot of potential upgrades, she could ask for new gear, she could ask for a new place to stay, she could do a lot of things but none of them really sounded appealing. Only one did, and that one was the one that brought a soft blush to the adorable Buster Baby's cheeks. "M-Mama... I want Mama's milk..." She muttered and looked down at her padding as shame filled her body. At least the nice flower-covered diaper was nice and big and really distracting, the young girl pushing her thighs together to make it look even bigger...

A soft giggle left the lips of her precious Mama. "Is that really all you wanted, dear?" Messiah asked, and Valentine quietly nodded as she was very honest about her feelings. "Very well. Then drink to your heart's content, little Valentine. You've earned every tiny little droplet..."

Just like that, Valetnine's eyes snapped back up to the matron's breasts. And she could feel the drool running down her chin. She could feel her heart pounding as she stared at those enormous milky mounds. She wanted them. She needed them. And when she needed something, she was going to take it. There was no other way around it. Somebody like her didn't have the ability to resist her inner needs...

The young girl wrapped her lips around her Mama's nipple and quickly started suckling. She could immediately feel the milk pouring down her throat, and the warmth that came with it hitting her tummy. It felt so good to slurp down Mama's milk. So much so that her eyes started to lose their color ever so slightly. Because drinking that milk made her lose control of herself.

Not just because she started to drink so much of her Mama's milk that her mind couldn't process it all... But because the milk was practically going straight through her, as cute little brassy farts left the little girl's bottom, and the back of her plain diaper started to sag as she made another quick mess. She wouldn't notice it while she was still drinking, nor would she notice anything but the love her Mama gave her.

Even as Mama Messiah patted her on the head and rocked her back ever slightly, she noticed nothing. She was in total and utter bliss, her reward for being such a good Buster Baby...

Messiah smiled. Once her little Baby had finished enjoying herself, she had a very important thing to tell her. About her future from that point onward...

And 'Cupids' that would keep her lonely butt company...
