Bulma's Blunder (Patreon)

This was an emergency commission for a client who said he was going into a life saving (or ending) surgery. Due to the seriousness of the situation this commission preempted all my other work, but I'm still currently working on the other stuff. That said, this is a very messy story and deals with dirty diapers. Proceed if you like that type of thing.


---BULMA'S BLUNDER---


Bulma smiled as she gazed out into the living room. Her retro themed costume party was going incredibly well. All of her friends had shown up wearing some very good outfits reminiscent of their youth, but she was certain that she was the best dressed among her friends. She was wearing her oversized pink shirt with her name emblazoned on the front and a belt across her waist to secure a blue satchel. Her outfit didn't stop at her shirt and sneakers, she even got extensions for her hair so that she could braid it into a ponytail complete with a red bow to really nail her classic look. 


Across the room she saw Videl who was wearing her Great Saiyawoman disguise from her high school days chatting it up with Master Roshi who was dressed in his Jackie Chun disguise. Opposite those two was Chi Chi and Goku. The latter was dressed in his original Gi from when he trained under Master Roshi so it wasn't like the big lug put much effort into his costume, but it was what the typically modest housewife was wearing that really caught Bulma's attention. The light-skinned woman was wearing her armored blue bikini, matching white boots and gloves and had her pink helmet on topped with a sharp blade. Her long, straight black hair had been freed from ifs bun and flowed down the back of her green cape. 


Even Vegeta and Krillin had gotten into the spirit of things. Vegeta was wearing his Saiyan Armor and Krillin literally had a giant turtle shell on his back. It was fun to see that the boys dressed like their younger selves, but there was one guest who had seemingly taken things a bit too literally. Bulma had to double take as Eighteen walked into the room wearing a diaper underneath a red dress. In fact, she looked like an older copy of her young daughter. It only took a moment for Bulma to make her way over to where Eighteen stood holding her daughter. 


"I wasn't expecting you to dress up like a baby." Bulma chuckled to herself, trying not to sound rude. "Why didn't you wear that outfit you used to wear when Cell was running wild?"


"To be honest, I'm not proud of what I did during that time and wearing those clothes would just bring up bad memories." 


"That makes sense, but why the dress and the diaper?" Bulma asked, genuinely curious. 


"Well, I don't really have any memories from before Dr. Gero got a hold of me so I decided to dress like my sweet little Marron." Eighteen grinned before giving her baby girl a kiss on the head.


"Then you won't qualify for a place in the costume contest since you're dressed like Marron and not yourself." Bulma replied.


"That's a bit unfair, don't you think?" The blonde asked.


"I think It's perfectly fair since that's the theme of my party." Bulma explained.


"How about we let our friends decide who has the best costume?" Eighteen countered, feeling confident that her cute outfit would surely win.


"Alright, deal." 


Bulma watched the diapered blonde walk over to where Krillin was sitting at a table with Master Roshi and Goku. Both men immediately responded to her rather unique outfit, especially Master Roshi who was bleeding from the nose due to the amount of leg the blonde's tiny red dress was exposing. 'Who would've thought the old perv could get so excited over long legs and a disposable diaper?'


The overwhelmingly positive response didn't stop with Goku, Roshi or Krillin. It seemed that even Chi Chi and Videl were fawning over the adult baby. 'Geez, this is ridiculous. Eighteen's going to win this contest if I don't act fast but what can I do to get her out of that costume?'


'Act fast?' Bulma repeated the phrase in her mind until she had an epiphany; 'My dad just developed that new hyper lax formula! If I can sneak some into her food she'll poop herself and have to change out of that ridiculous outfit which will allow me to win the contest!'


Wasting no time, Bulma slipped out of the room and rushed down to the lab where her father was busy tinkering with something at his work station.


"Hey, dad. Do you know where the hyper lax is?" Bulma asked, trying to be quiet about it.


"Oh, It's over there on the shelf in one of the vials. I haven't exactly had it properly tested yet so I wouldn't recommend using it." The older Brief explained while never looking up from his workbench.


"Thanks for the heads up." 


Silently, Bulma walked over to the shelf her father had blindly gestured towards and picked up a small vial containing a translucent fluid. Holding it in between her thumb and index finger, the blue haired scientist took a moment to examine it before putting it into her satchel. With the hyper lax safely in her bag, Bulma quietly left the lab and was on her way back to the living room when she noticed her mother leaving the kitchen with a massive cake on a push cart.


"Oh, hi honey." The middle aged blond smiled, greeting her with a wave.


"Mom, is that the cake you've been cooking on all day? Bulma couldn't believe her eyes, it was huge!


"Yeah! I wanted to make enough cake to feed everyone, including the boys." The blonde explained with a giggle.


Ever the quick thinker, Bulma devised a devious plan that would simultaneously knock Eighteen out of the contest and secure her first place. "How about you take a break and I'll push the cake out to the living room?"


"That would be great, sweetie." Panchy smiled, wiping a bit of sweat from her forehead. "I've been on my feet all day."


"Relax, mom." Bulma took her mother's place behind the push cart. "I got this."


Bulma didn't wait for her mother to reply, she started pushing the cart that held the massive chocolate cake on top of it. She brought the cake to a stop just outside of the living room and, acting quickly, the blue haired inventor pulled out a vial and poured a few drops onto the right side of the cake. It wasn't enough to taint the entire thing; just the area she would personally cut and serve to Eighteen. 


With the hyper lax strategically applied, Bulma pushed the cart out into the living room and announced her arrival to her friends and family. "Alright everyone, the cake is here!"


Goku and Vegeta spun around, eyeing the cake like the gluttons they were, but that was to be expected. Bulma kept her eyes on Eighteen who was following behind Krillin and Goku. 


"What flavor is it?" The strongest man in the universe asked.


"It's chocolate frosting with a yellow center, Goku." Bulma explained, handing him a plate with a big slice of cake on it.


"My favorite!" The Saiyan easily ate the slice in one bite right in front of her. "Can I get another slice?"


Bulma chuckled. "I'm glad you liked it, Goku, but I have to make sure everyone else gets a piece before I can start giving out seconds." 


"Okay, That's fine, I'll just get more after everybody gets a slice." 


Bulma proceeded to hand out a plate to each one of her guests after Goku walked away. Krillin got a slice after her husband which allowed Eighteen to step forward. It wasn't easy to cut a slice from the opposite side of the cake without looking suspicious, but Bulma easily explained it away saying that she wanted to make sure that everyone got an end piece before she started handing out center cuts. The blonde didn't question her explanation and took her plate.


'I can't wait for her to finish that slice. She'll be pooping that stupid pamper in a few minutes tops!'


The blonde started eating her slice, taking small bites from it unlike Goku, and all was going according to plan. That was until Eighteen's face froze and she dropped the plate she was holding. It took roughly a minute after consuming a few bites of the cake for Eighteen to double over, clenching her stomach, looking like she was about to shit herself. Krillin rushed over and asked if she was alright, but the only response he received was a pained groan followed by a massive muffled fart exploding into the back of her diaper. It hadn't even occurred to Bulma that the hyper lax would be so potent or work so quickly. In fact, Bulma immediately realized that the hyper lax was way too strong when she noticed Eighteen's rapidly growing diaper that started drooping lower and lower until it was hanging just above the blonde woman's knees!


"Eighteen!" Bulma heard Krillin call out to his wife as the blonde dropped to her knees. 


Everyone started gathering around the stinking blonde forcing Bulma to push her way past Piccolo and Tien to get close to Eighteen.


"What happened? Are you alright?!" Bulma asked with legitimate concern in her voice.


"I-I'm fine." Eighteen stammered while trying to pull down the front of her red dress over the bloated, bulging, discolored diaper that was pressed against the floor.


 Bulma leaned forward, offering her hand to help the blonde woman to get back onto her feet. Just because she wanted to knock Eighteen out of the costume contest didn't mean she wanted her to poop her pamper until it weighed her down like a stone. While helping Eighteen up to her feet the baby blue satchel on Bulma's hip opened up, causing Bulma's lipstick, mascara and the vial of hyper lax to spill out onto the floor.


Seeing the vial of hyper lax rolling away from her caused Bulma to freeze in place. She hoped that Eighteen wouldn't notice it due to the heavy load hanging between her legs, but it seemed that fate was conspiring against her. The blonde immediately reached out with her hand and picked up the vial before it could roll any further. Bulma watched with baited breath as the blonde looked over the vial that was labeled "experimental hyper laxative." The startled expression on the blonde's face suddenly turned bitter and angry as she turned to face Bulma. 


"Did you do this to me?" Eighteen asked, her voice cold and direct. 


Bulma was at a loss for words and simply stood there. It was obvious that she was guilty but she couldn't bring herself to admit her guilt. Luckily for her, Eighteen didn't wait for her to answer and stormed off towards the bathroom, her bloated backside swaying which each step she took which made her look like a giant baby waddling away in a dirty diaper. 


"What was that thing in Eighteen's hand, Bulma?" Krillin asked, looking over his oldest friend with a suspicious gaze.


"Yeah, what was she talking about?" Goku chimed in, genuinely confused by everything that had happened thus far.


Bulma could feel every eye in the room looking at her, suspecting her. The woman who had an answer for everything was stunned into silence. Not only did her plan fail spectacularly but she couldn't help but worry about Eighteen. 'Producing so much waste at once cannot be good for the digestive tract.'


The others who had circled Bulma were quietly chatting amongst themselves, trying to figure out what was going on. Bulma could only make out what Chi Chi and Videl were saying; something about how they've never seen such a full diaper before.


Everyone in the room suddenly ceased talking the moment Eighteen reentered the room. The blonde had changed out of her red baby doll dress and was wearing her purple and blue top, but for some reason she was still waddling around in her drooping disposable diaper. Bulma realized that the pampered blonde was marching towards her with a pink diaper bag slung over her shoulder. 


 "I was going to change out of this disgusting thing hanging from my hips and take my family home, but what kind of lesson would that be teach my daughter if I just walked away without punishing you for what you did to me?" Eighteen asked, face to face with the blue haired woman as she confronted Bulma. 


"I never expected that to happen!" Bulma blurted out before covering her mouth with both of her hands.


"I don't care." The blonde replied bitterly. "You should've never done this to me in the first place."


Before Bulma could even respond she was caught off guard by the strongest female fighter on Earth grabbing her by her midsection and laying her on the floor.


"VEGETA, SAVE ME!" Bulma shrieked from her position underneath Eighteen's bulging diaper. 


"Stop right there, Eighteen!" Vegeta demanded as he stepped forward from the crowd. 


"I'm not going to hurt her; I'm paying her back for this!" The blonde replied as she held up the vial of hyper lax while keeping Bulma pinned down on the floor with her free hand. "She obviously spiked the cake with this crazy concoction cooked up in her lab."


Vegeta gazed at the vial held in between the blonde's thumb and index finger. "Is this true Bulma?"


Bulma couldn't utter her guilt outloud so she merely nodded her head. 


"What the hell, woman?!" Vegeta exclaimed. "I could've eaten that piece of cake you poisoned!"


"I would never-" Before Bulma could finish Vegeta cut her off.


"Do with her as you please." Vegeta said, his back turned away from his wife.


"But Vegeta!" Bulma begged, flailing her arms and legs like a brat having a tantrum.


"You've earned this." Bulma's entire body tensed as she felt Eighteen's hands glide slowly up her long legs towards the hem of her oversized pink shirt. 


"Eighteen, pleas-" A single finger silenced Bulma.


"If I hear another word you won't be able to sit down for a month."


Bulma laid still, not wanting to temp the already angry fighter who started sliding her white cotton briefs down her shapely legs. A blush spread across Bulma's face upon seeing the rather childish looking underwear that she had painstakingly procured just for her costume. She hadn't expected anyone to actually see her cotton white panties with the little pink bow; they were supposed to be a treat for her husband after the party had concluded but now everyone was getting a good look at her underwear!


"Now It's my turn." The blonde announced as she ripped off the tape securing the diaper on her right hip.


Bulma's eyes went wide when the heavily soiled diaper fell from Eighteen's dirty crotch and fell to the floor with a sickening plop. Even their assembled friends and family were stunned by the sight of the blonde's shit covered ass cheeks which were prominently on display for all to see.


"Just a minute." Bulma heard Eighteen murmur to herself as she fished out a package of baby wipes and promptly tore a handful from the plastic pouch. 


The blue haired scientist watched the blonde clean herself using wipe after wipe to rid her body of filth. If this was Eighteen's idea of a punishment then it was very weird but also something that she would never forget. She was about to open her mouth and ask Eighteen if the punishment was over when she remembered the woman's warning about talking. So Bulma laid there quietly, hoping that this strange situation would soon come to an end. Just when she thought Eighteen was finished she watched the blonde crouch down onto her feet and pull out another adult sized disposable diaper.


'Great.' Bulma mentally sighed. 'She's going to diaper me to prove her point.'


Much to the blue haired inventor's surprise the blonde unfolded the diaper and threaded it in between her legs before pulling it upwards. 


'Why is Eighteen diapering herself?'


It took only a few seconds for Eighteen to finish taping herself into the new diaper and, once she was snugly padded, she reached down and picked up the outstretched diaper full of shit. 


"What are you doing with that nasty thing?!" Bulma demanded with a hint of fear in her voice.


"Punishing you." The blonde replied as she knelt in front of Bulma and got to work.


A loud scream rang out in the large living room followed by a flurry of weak kicks, but Bulma's pitiful resistance was no match for Eighteen's speed and strength. 


"Ewww!" Bulma shrieked at the top of her lungs when her bottom was lowered into the warm muck coating the interior of Eighteen's used diaper. 


The blonde struggled to stifle her smile as she pulled the front of the dirty diaper over Bulma's pussy before taping her into the putrid pamper.


'This is disgusting!' Bulma shivered at the sensation of the used diaper being pulled tightly against her pussy. She found herself taped into the sickeningly bloated, lumpy mess that was once Eighteen thoroughly used diaper in under a minute. To make matters worse, Eighteen decided to finish the diapering by patting the front of the bloated diaper, causing the soft shit in the bottom of the plastic backed disposable to spread and enter into her every crevice. 


"Alright, let's get your highchair ready."


Bulma watched as Eighteen grinned and flung a nondescript capsule gently to the ground. The white capsule instantly exploded upon coming into contact with the floor, releasing a cloud of smoke into the air. Bulma lost sight of the blonde, who was momentarily engulfed in the smoke until it dissipated, leaving behind an incredibly large, red high chair standing in the middle of the living room. It took Bulma only a second or two to realize that such an infantile chair could easily accommodate a woman her size.


"Where did you even get that?" Bulma heard Chi Chi ask.


"It's a regular capsule that I had Dr. Briefs tweak to be large enough to fit me. It was supposed to be a fun addition to my costume that I was going to use when we were all showing off our costumes after dessert, but now It's for Bulma."


With that said, Bulma watched as Eighteen bent forward and picked her up off of the floor. The blonde had her arm across Bulma's back, gripping the blue haired woman's belt for leverage while lifting her up onto her hip in a single smooth maneuver. Bulma could feel her face growing hot, an awkward blush spread across her cheeks, as she was carried like a baby towards the adult sized high chair. 


Bulma would've never imagined that this was what Eighteen had in mind when she started talking about punishing her!


'This is so degrading!' Bulma lamented while being carried on the blonde's hip. 'At least she's about to put me down. I'd rather sit in a stupid highchair than be held like a ba-'


Everything slowed to a standstill as Bulma felt her padded posterior being lowered into the highchair's seat. Bulma squealed when her body weight pushed the lump of shit beneath her ass into the thick inner shell of the diaper. In less than a second Eighteen's mess rapidly spread everywhere, thoroughly coating both Bulma's backside and the few remaining untouched areas of the diaper in poop. It felt so horrible that Bulma couldn't stop herself from fidgeting and squirming around in the seat which only made the mess rub against her bottom and pussy.


"You're only going to make it worse by squirming around like that." The blonde observed with a smirk as she placed the tray into the rest of the highchair, literally locking the world's smartest woman into an adult sized highchair. 

 
Bulma immediately stopped wriggling around and blushed. She hadn't realized how babyish she looked nor did she know just how much there was inside of the diaper until she had to sit in it.

  
"Come on, Bulma. Open wide for the yummy cake your mommy baked." The blonde cooed with a snicker as she held up a slice of the tainted cake to the diapered scientist's mouth.


Bulma glared back at the blonde. She may have crossed the line and earned some kind of punishment for spiking Eighteen's slice with laxative but it definitely wasn't whatever this was! Just because Eighteen wanted to humiliate her didn't mean that she had to go along with it without putting up some sort of active resistance. With that thought in mind, Bulma kept her mouth shut, hoping that the blonde would grow bored with whatever this was and release her from this infantile chair. 


Sadly, Eighteen wasn't going to play Bulma's little waiting game. After a few tense moments passed, the blonde grew tired of waiting and reached out with her thumb and index fingers. Bulma didn't have time to react and felt her nose become pinched in between Eighteen's fingers.


 'You've got to be kidding me!' Bulma internally fumed as her lungs rapidly started to burn. She didn't have the weakest lungs in the world, but after years of smoking cigarettes she couldn't exactly hold her breath more than a minute. 


With her lungs burning from a serious lack of oxygen, Bulma opened her mouth and swallowed more than just her pride as she accepted the slice of cake. Unlike Goku or the other Saiyans, she couldn't eat an entire slice in one bite so she simply took to taking much smaller bites until the large slide was gone. Much to Bulma's surprise there wasn't a hint of anything in the cake that wasn't supposed to be there; the icing tasted sweet, the moist fluffy interior tasted delicious and each bite she took practically melted in her mouth like cotton candy. Still, she knew better than to think that Eighteen gave her a normal piece.


A muffled fart caught Bulma's attention and she briefly wondered if it came from her when she noticed that Eighteen's once jovial expression had turned sour. The blonde was now scowling as her diaper was literally growing by the second. Bulma couldn't believe her eyes as the once pristine adult sized pamper between Eighteen's thighs started to show signs of discoloration as it sagged. Somehow it was still able to hold its shape while sinking a few inches towards the floor and looked just as bloated as the diaper that Bulma was now wearing. 


No one in the room uttered a sound upon witnessing Eighteen poop her pamper for the second time that evening. The only sounds that could be heard were coming from Eighteen's bottom while the occasional groan escaped from her tight lipped mouth. 


"I had a feeling that might happen." The blonde muttered to herself before scooping up another slice of cake. "Don't worry, I'm not going to put you in this one."


Bulma opened her mouth to plead with Eighteen and the blonde quickly shoved the entire piece of cake into Bulma's mouth. 


"Uhm!" Bulma gagged, struggling to consume the whole thing before she finally managed to swallow it.


The blue haired scientist was literally trapped in an adult sized highchair with a dirty diaper strapped to her ass while Eighteen held out yet another piece of cake; she had zero chance of being able to get free, but it wasn't until her guts started to churn that she realized just how much worse things were about to get.


"Ugh." A pained groan left Bulma's mouth as she ignored the slice of cake Eighteen was pushing towards her lips. She couldn't help but wrap her arms around her tummy as a muffled fart escaped into her already soiled diaper. 


"I have to go really bad." The scientist muttered to herself absent mindedly as she tried her best to hold it in.


The blonde looked at Bulma, who was struggling to hold in her shit, and grinned. She knew that it was only a matter of time before Bulma crapped her huggies just like she had done.


"Please! Let me use the toilet!" Bulma begged. "Don't make me poop in this disgusting diaper!"


"Why should I let you use a toilet?" The blonde asked, holding the slice of cake inches away from Bulma's lips. "You made me poop my diaper so I think It's only fair that you experience the same pain and humiliation that I felt."


"No!" Bulma shrieked. "Just let me use the toilet!"


However, even if Eighteen let her get out of the highchair, her body had other ideas and was working overtime to push her first turd into the back of her already dirty diaper. It didn't seen to matter how hard she tried to clench her asshole shut, the hyper lax was overpowering her muscles, allowing a massive log to slowly force it's way out. With a grunt, Bulma could feel her asshole starting to open up to make way for the outgoing mess. Squeezing her sphincter tighter only cut the tip of the log off, forcing it to fall into the pile Eighteen had left in the diaper. 


Bulma whined as she continued to fight against her body which made her bottom sweat and quiver, but had the desired effect of momentarily delaying the inevitable. She felt her breathing intensify as her anal passage started pulsating with every inch of the log that was being pushed out of her. A pained groan passed through her lips as the need to poop overwhelmed her stubborn pride. Bulma felt her face grow hot; her body was actually betraying her and there was nothing she could do to stop it! Her ass cheeks were spreading apart slowly, allowing the long log to exit from her asshole and enter into the seat of her diaper. However, the wet snake of shit didn't simply drop into her disposable underwear, it coiled up when it made contact with the pile already occupying the seat of her already soiled diaper. The pressure from shitting caused some pee to leak out and join the large pile that was growing even larger as a huge bulge appeared in the back of her diaper.


Bulma saw Eighteen's smile grow even wider and the humiliated scientist hid her eyes behind her hands as muffed and smelly farts erupted into her diaper. She couldn't face her friend turned tormentor. It was bad enough that she was actually shitting herself in front of all of her friends, but knowing that she had practically put herself in this vulnerable situation only made it worse. 


"Okay, I pooped myself!" Bulma whined before adding, "are you happy now?!"


"I'm not going to be happy until you finish all of your cake and fill that diaper till it touches the floor." The blonde answered while pushing the spoonful of tainted chocolate cake into Bulma's mouth.


"Bu-" Bulma paused, chewing on the cake and swallowing it before trying to speak again. "But that's impossible! This diaper can't hold that much poop!"


"You're a scientist aren't you?" Eighteen asked with a mischievous smirk . "Let's do a little experiment and see just how much poopie you can pack in your pamper!"


Before Bulma could utter a word her legs started trembling against the high chair's footrest as wave after wave of soft poop flowed out of her body, joining the pile of firm turds lining the contours of her diaper and caking against her cheeks and shaved crotch. She could feel the diaper extend out from her ass as she bore down, falling off the sides of the highchair's seat as she kept pushing as hard as she possibly could to rid her stomach of the pain. Bulma wriggled around, trying to shift her weight which caused the top of her diaper to slightly pull away from her aching tummy. The short lived gap pushed the stench inside of her diaper upwards, forcing Bulma to smell the putrid stink of her dirty diaper wafting around her body. The poor forty two year old struggled not to gag as the smell overwhelmed her nose. 


Bulma lowered her hands and opened her eyes only to be met by Eighteen's gaze. The blonde had a smug look on her face like she was standing over an opponent who had been bested in battle, but Bulma lost more than a simple fight; she had thoroughly defiled herself. The CEO of Capsule Corp had literally pooped herself not once but twice! All she wanted was to be the one to stand over Eighteen as she pooped diaper and then win the costume contest, but now she was being thoroughly humiliated by that blonde bitch!


"Now quit your fussing and open wide for more cake." Eighteen ordered, her hand hovering over the remaining half of the once massive cake that Bulma's mother had baked for the party.


"NNH-No more… I can't eat another bite…" Bulma said, struggling to find the words before Eighteen literally picked up a big piece of the cake off of the highchair's tray and pushed it into her mouth. 


"MMPH!"


Bulma's cheeks puffed out from all the cake in her mouth as she struggled to chew the fistful of sinfully soft confectionery that Eighteen had pushed into her mouth. She could only blush at the blonde as she kept chewing on the cake. Crumbs cascaded down her chin and the front of her oversized pink shirt before ultimately landing on the tray of the highchair. With each slice she eat she felt more bloated and full. Deep within her gut she could feel the cramps returning which could only mean one thing; she was going to poop again!


Of course, Eighteen was completely oblivious to Bulma's distress. She was openly cooing at her as she brought yet another piece of cake up to her face. A rather loud fart caused the blonde to pause and hold the slice of cake in place as Bulma closed her eyes shut. 


Bulma could feel the seat of her disposable swelling outwards as a symphony of crinkles came from underneath the highchair's tray. The diaper was rapidly expanding, ballooning outward and spilling out of each and every side of the seat. Suddenly, she felt her legs being spread apart by the bulbous load which was now shifting and spreading. The back of her abused diaper gradually grew until it hung off the end of the infantile chair's seat while the front of the disgusting disposable was digging into the highchair's safety strap which seemed to contain the growing diaper briefing until it snapped open, allowing the front of the diaper to expand forward.  


With one final push Bulma sighed and slumped back against the backrest. She felt exhausted after pooping so much and wished Eighteen would stop feeding her.


"Please, no more." Bulma begged, her belly feeling almost as bloated as the enormous diaper she was stuck in.


"I think the baby has had enough cake for tonight." Eighteen said, more for the benefit of her assembled friends than the exhausted blunette in the highchair. 


"Really!?" Bulma exclaimed, perked up and filled with renewed hope that this absurd punishment was finally coming to an end.


"Yeah." Eighteen replied before turning her back to Bulma. 


Bulma couldn't see what the blonde was doing, but it sounded like she was digging around in the pink diaper bag. For a brief moment Bulma thought she heard Eighteen pouring something into a container until the sound stopped. Eighteen stood up from the bag and turned around with a full baby bottle in her hand. 


"All you have to do is finish this bottle and I'll change your diaper." Eighteen explained with a grin as she held the bottle in front of Bulma. 


Bulma looked over the liquid in the bottle before accepting; it looked just like everyday water. She would've preferred milk after having to eat so much cake, but anything was better than nothing. The taste of the latex nipple of the baby bottle was a stark contrast compared to the sweets she had just consumed, but Bulma knew that she had to suck on the nipple if she ever hoped to finish the baby bottle which she held in both of her hands. It took a few firm suckles until the water trickled into her mouth. Almost immediately she realized that she needed to hold the back of the bottle higher than the nipple if she wanted to keep a steady stream flowing into her mouth. It didn't take long for the forty two year old's lips to work themselves into a rhythm which allowed her to drain the bottle at a fairly fast pace.


Bulma was so preoccupied with sucking on the bottle that she failed to notice Videl and Chi Chi snickering amongst themselves as Vegeta watched her debase herself with a scowl. Unlike the mothers, who were enjoying the show, the Prince of Saiyans hated seeing his wife humiliate herself like this, but he was also a man of honor and knew that Bulma had earned this strange punishment. In a way, it did seem fitting albeit bizarre, but she shouldn't have tainted Eighteen's piece of cake. Meanwhile, Goku and Gohan stood there trying to comprehend why this was still going on. The older Saiyan didn't really understand the concept of humiliation while his son simply thought that Eighteen had proved her point long ago. Roshi on the other hand was enjoying the show for an entirely different reason; cute women dominating each other in such an odd way wasn't exactly on his list of turn ons, but the old man was open minded and was currently contemplating if a magazine showcasing women in diapers even existed.


Eighteen couldn't hide the grin on her face as she watched the smartest woman on Earth drink the baby bottle. In some ways what Bulma was doing was far more humiliating and infantile than simply shitting herself. The combination of Bulma sitting in a highchair, in a dirty diaper, as she sucked on a baby bottle that Eighteen usually gave to Marron was just so babyish that the blonde couldn't even put it into words. Eighteen had defeated numerous foes in her time, but the feeling she derived from making Bulma poop her Huggies and drink from a bottle was something that she had never experienced before; it was a feeling of power that no victory had ever given her.


Bulma suddenly felt air coming from the slit in the latex nipple and realized that she had finished the water. She placed the baby bottle down onto the plastic tray and crossed her arms over her chest. "I'm done."


Barely a second passed before the blonde fighter pulled the tray out from the highchair and scooped Bulma out of the seat. If Bulma had blinked, she would've missed it; that's how fast Eighteen was moving. Unlike earlier, Bulma wasn't held in the air or placed on Eighteen's hip, she was immediately laid onto the floor in the center of the living where the changing mat awaited her. 


Bulma laid back and felt the diaper underneath her thighs move around like some sort of bizarre amalgamation of jello and a plastic bag. In the back of her mind Bulma quietly cursed herself for designing such a durable material that could hold so much waste. She had never experimented or tested the diaper to this extreme and she would've been pleased with the amount it was holding if she wasn't literally laying in a massive pile of her own poop!


"Lift your legs up." Eighteen's voice interrupted Bulma's thoughts.


Bulma quickly lifted her legs, eager for Eighteen to remove the sagging soiled diaper from her. The weight of the diaper shifted when she moved into position, pulling at her waist as the muck shifted and gathered underneath her raised bottom. She felt Eighteen's fingers brush against her hips as she moved her hands towards the tapes holding the heavy bag of crap around her waist. There was a loud tearing sound as the adhesive was ripped from the diaper before Eighteen moved over to the other side and repeated the process. Suddenly, Bulma felt air on the bottom of her tummy as the blonde pulled open the front of the disposable, exposing Bulma's poop covered crotch to everyone. 


"Uuuuugh!" Bulma couldn't help but scowl, internally cringing as she felt the weight of the dirty diaper leave the front of her body. 


"I hope you learned your lesson." The blonde cooed down at Bulma while reaching forward with an extra large baby wipe. "If I wasn't such a nice person I'd make you clean up your little mess."


The condescending tone of voice Eighteen used while Eighteen began to clean her made Bulma close her eyes as an intense feeling of shame washed over her. She just wanted to forget that this horrible night had ever happened, not be reminded of it! However, Eighteen was doing her best to drag it out even though she was working quickly. Bulma had to draw in a sharp breath the moment the ice cold wipe finally touched her bare skin. A laugh came from Eighteen whose firm hand was pressing into Bulma's skin, pulling downward, wiping away the mess that was all over her pussy and ass. Try as she might, Bulma couldn't block out the feeling of Eighteen's hand wiping her ass and shuddered when all of the thick muck coating the area between her legs was pulled away from her skin and into the seat of her thoroughly used diaper.


"Lift up your butt and spread'um." The blonde's voice was firm but had a playful edge to it.


'She's enjoying this way too much!' Bulma lamented but eagerly compiled. She could feel the sickening feeling of excrement coating the inside of her ass and knew that Eighteen would need to wipe it away if she ever hoped to keep her future diaper clean.


"Good girl!" Bulma sighed in annoyance upon hearing Eighteen praise her for spreading her legs even wider.


"Eep!" A startled sound of surprise escaped from Bulma's mouth upon feeling Eighteen swirling the wet wipe around the rim of her asshole, cleaning her filthy hole. 


The majority of her friends and family remained silent which helped Bulma forget that they were even present. Still, she could hear the occasional murmuring coming from Chi Chi and Videl while her son and Goten tried not to laugh as they stood by their stoic fathers' side. 'At least Goku isn't saying anything.' Bulma thought. 


Without warning Bulma cried out in shock as she felt Eighteen plunge her wipe-covered index finger up her tight asshole. Bulma winced and groaned slightly from the unexpected intrusion. Bulma looked up at Eighteen, watching the blonde enjoying herself, the smile never leaving her face as she cooed down at Bulma. Finally, Bulma felt Eighteen's finger pop out from the scientist's freshly cleaned ass. 


'Ugh, I wish she would hurry this up already.'


As if she had read her mind, Bulma felt Eighteen's hand hold her by her ankles as she started pulling the dirty diaper out from underneath her bottom. The blonde was strong enough to remove the enormous diaper. She quickly balled up the disgusting disposable and placed it off to the side. The sight of the huge balled up diaper sitting only a few feet away from Bulma was both terrifying and magnificent. She couldn't believe that her body was able to produce so much waste in the first place, but that would explain why her father had warned her that it wasn't ready to be used.


With her legs still hoisted above the changing may Bulma noticed that Eighteen's free hand was busy sliding a fresh diaper underneath her now clean bottom. Even though she was going to be put into another diaper, Bulma was happy to feel clean again. The thought of having to be in diapers for the next few days to fully allow the hyper lax to completely go through her system still annoyed her, but at least she would be able to get through that in private without all of her friends watching her poop herself at random. 


An unexpected flurry of white dust engulfed Bulma as Eighteen poured baby powder all over Bulma's raised ass which caused the blue haired mother to sneeze.



"Watch where you're dumping that!" Bulma whined as Eighteen finished powdering her butt.


"You don't want a rash, do you?" The blonde replied with a grin.


'At least It's clean this time.' Bulma thought to herself as her freshly powdered bottom was lowered her onto the soft surface of the pristine pamper.


Another flurry of dust enveloped Bulma when Eighteen resumed dumping the thick talcum powder across her crotch and tummy. 


"Now let's get you into a nice diaper." Eighteen smiled as she sat the container of baby powder down.


Before Bulma could utter a word, the blonde grabbed the front of the disposable laying underneath Bulma's plump ass and pulled it over her crotch. The tapes were each torn from their adhesive and stretched out until one by one they were pressed into the landing strip of the diaper. 



"All done." Eighteen announced while patting Bulma's thickly padded crotch.


"Thanks…" Bulma muttered to herself as Eighteen offered her a hand.


The diapered scientist was helped up from the floor and blushed when she realized that everyone was still staring at her; The diaper may have been clean but she was still wearing a diaper. An awkward silence persisted as Bulma watched Eighteen walk away from her, the blonde's heavy load caused the disposable to sway from side to side. 


Despite having endured the punishment, Bulma still felt uneasy and mildly uncomfortable with how things stood. Her tortured tummy still ached and it felt like something was stirring in the pit of her stomach. She groaned as an intense cramp rocked her midsection; somehow this felt worse than before! A steadily increasing pressure was building in her gut until it started pulsating from the bottom of her stomach while rapidly making its way down her intestinal tract. Bulma was so caught off guard by the powerful pain traveling through her body that she barely realized that she was already filling the back of her diaper once more. It took a few grunts and pushes but after the initial torrent of fetid liquid she could feel more solid pieces slide into the saturated seat of the diaper. Once again the plastic shell contained her latest monstrous mess and continued to accommodate it while gradually expanding until it hit the floor.


A seemingly never ending heat was not only radiating from his face but from the back of her diaper as Bulma blushed, struggling to comprehend how she was able to poop so much. She had lost count of how many movements ended up in her diaper. For a moment she tried to deny to herself what had happened, but the heavy weight tugging at her hips as tight material stretched to contain her latest accident served as an omnipresent reminder of what she had just done. 


"Now we're even." Eighteen announced from the other side of the room before disappearing into the bathroom.


The End
