When I first started training with my hero and idol Son Gohan to battle the android, Of course my goal was to save the world. It became even more important to me after he was killed in a battle with the twin beasts. 
Ironically while I've failed to destroy them and lost more then I could ever thought possible, I've done just that since the androids are too busy with my ever lasting torment and humiliation to bother with the rest of the world.
My name is Trunks Briefs, and THIS is my story.

It all started after my failed attempt to kill the androids. a young half super sayien giving it his all to avenge a fallen mentor, I had deluded myself into thinking a stood a chance. 
The notion I stood a chance was quickly beat out of me after they shrugged off my best attack and knocked me around like I was the red headed step child, then openly started to mock me and getting in my head. 
"Awww, Isn't that the toddler that used to hang out with lefty?"
"Sure is! Look who graduated to big boy pants!"
At this point I'd lost the ability to hold my super sayian form and had been hiding in one of the building they had cleared out, desperately trying to control my breath AND my bladder. 
"Awww, look who thinks he's the champ at hide and seek!" 18's voice rang out, making me look around, the bare control I had on my bladder starting to slip. 
"T-Their bluffing.." I muttered to myself, forgetting that among their many enhancements, hearing was one of them. 
"Peek a boo." Came 17's voice, a second before he burst though the wall behind him, stopping in front of me and looking over his shoulder. "I found you." 
even as he backhanded me, sending me flying though was was left of the wall and crashing onto the earth below, my bladder gave way and my light grey jeans did nothing to hide the fact.
"Awww, did baby fall down and go boom?" 18's voice rang out. 
my eyes were closed in pain and shame and I was trying to get up, but her foot came down on the back of my head.
"Awww don't worry, I'll make it all bet- ..Holy shit! 17! The bitch pissed himself!" 18 called out, going from condescending to outright amused, laughing.
"No way!" 17's voice called out, then it was much closer. "Hahahaha! Oh wow! we have a widdle pants wetter!"
"Sheesh, we better finish it off not before baby craps his underoo's." 18 said, and I managed to open my eyes enough to see her looking down at me with a sneer. 
Oddly 17 was brushing at that and then reached out and grabbed his sisters hand, pulling it back.
"Wait.." He said. 
She went from confused to annoyed and let out a massive sign. 
"oh god, not again! This never works out and you know it! they break to easily!" She ranted. 
"But these golden haired weirdos are more durable! come on, Pleassse! I promise I'll handle everything this time!" 17 said and I was MORE then confused as he gave his sister puppy dog eyes and had his hands together. 
"I must have a concussion.." I muttered.
"Hush babykins! Daddies bargaining for your life!" 17 said, shaking a finger at me then turning back to his sister. 
"You SAY that but then I always end up having to change them because you like them in droopy diapers for hours on end!" 18 said.
Poopie diapers? Daddy? Babykin's? let's just say this red flag was fucking crimson and if I hadn't of been too hurt to get up I would of been flying for my life...not that I think it would of helped since I was pretty sure they were faster then me. 
"Please please please please please please plea-" 17 was saying over and over again until 18 let out a anoyyed sigh. 
"FINE! But if this one breaks, we're not getting anther!" she said and shook her head. "God, act your destination not your shoe size."
"yay! your the better robo twin ever!" 17 said and hugged her then crouched down to look at me. "Welcome to babyhood little guy! Oh..and sorry about this." 
Before I could even ask what 'this' was, His fist shot towards my face and darkness took over.

when I woke up I had a splitting head ache..well ok I ached all over but I was alive. the room I was in spun around and I was forced to close my eyes and take a few deep breaths to fight off a wave of nausea then I started to sit up. 
the bed I was on felt super soft and had a fuzzy sheet on it and I'd been covered in a light blanket I tossed off, eyes still shut when I felt something weird around my hips, and heard a crinkle. 
"...Ohhhh no..." I groaned, recalling what 17 had said before he'd knocked my lights out. 
Slowly I opened one eye and took a look around my new room which just as I had freed, was a semi nursery though it had been set up in a cave. I already knew what I'd see when I opened my other eye and looked down, or at least had thought I'd known. 
Clearly I was wearing a diaper, from the feel around my hips and the crinkles I was making, but it wasn't really visible unless you counted the bulge that it made under the white diaper shirt with a dino print on it that I was wearing. 
"Ok..Ok. Don't freak out. Maybe your just in a coma, and this is one of those deep dreams.." I muttered to myself, taking anther look around my cave nursery. 
It looked like it had at one point been one of the cave lab's that every mad scientist worth his tittle seemed to have (Heck, Mom even used to have one!) but any lab equipment had been replaced with a changing table, a rocking chair, dressers and a toy chest and well, last but not least the crib my diapered ass was sitting in. almost as a after thought since it didn't extend to the walls a rug had been put down. 
Standing up in the crib my head swam for a second and I almost plopped back down onto my newly pampered backside but instead i just held onto the crib rail and shut my eyes again, swaying a bit.
"Great..I'm dressed like a oversized baby and I have a concussion. can this get ANY worse?" I muttered out loud.
As it turned out I temping fate and that was one asshole you didn't wanna tempt. even as i finished my statement my guts churned and I hunched slightly, a old familiar need taking hold. 
"I just HAD to say something didn't I??" I complained to no one, though as I would later learn the room was wired for sound and 17 and 18 had been listening in and watching from hidden cameras with glee.  (They've often joked about maybe selling the footage for a hit reality series on Netflix..I just pray they're kidding.)
Just because I was wearing a diaper and the changing table and diaper pail told me what was expected of me, didn't mean I was gonna just sit back and crap myself however. I wasn't as bad as I've heard my father was but I still had my pride.
It was easy enough to get out of the crib, I didn't even need to fly though the movement didn't exactly agree with my goal of trying to keep my pants clean and I let out a 12 second ripper that would of had my mom running for a window and Gohan chuckling and telling me to name that sucker.
I was eyeing what I was gonna take a dump in as my hands moved down to open up the diaper shirt when suddenly there was a hard swat on my pampered behind that despite their thickness hurt and sent me stumbling forward and tripping, arms coming out so i didn't brain myself on the floor but ending up face down and ass up.
it also made what little control I'd had left go out the window and my back door opened up and unleashed it's own take on a big bang attack.
"Ah ah ah baby, no touching your dia- Heh..Jeez Kiddo, not wasting anytime huh?" 17 said, appearing in front of me and leaning down, going from wagging a finger at me to realizing what was happening.
"I..I..Shut up!" I said, and followed it up with the cutting insult of "Stop watching me poop you perv!" 
I'm sure despite the look of amusement on his face, 17 was torn to spreads by my witty insults...  Yeah it's a nice fantasy world I live in. you should come and visit sometime.
"Awww, Somebodies just cranky because Daddy had to scold him. it's ok..I know the next few days are gonna be rough so I'll go easy on ya." 17 said and ruffled my hair and patted my head in a manner that if anyone else had been doing it and I hadn't of been in the middle of shitting my guts out..might of been nice.
"heh, oh yeah, I can see it in your eyes, your gonna be a hostage taker. you needy daddy boys are. just gonna have to crack though that shell first." 17 said.
"I am NOT a daddies boy! and I will Never give into y- Ahh! Poopie!" 
while I had been in the middle of making my defiant statement and finished unloading into the seat of the diaper 17 had just smirked and reached back, and rubbed and squished the seat of the messy diaper in a way that was 70 percent gross and I hated it, and 30 percent  'oh, i could get to like that' 
Blushing I tried to will myself NOT to react with a stiffie from the wave of kinda nice feelings this was awake when a SHARP pain made me yelp out.
"OW! what did you do to my dick!" I cried out.
"Awww, did babykins try and get a widdle stiffie from having him's stinky butt pwayed wff? Ever kewt!" 17 coo'ed and chuckled, tickling my chin.
"Answer the freaking question!" I huffed, trying to sound scary but I mean.. let's recap: here I was in a diaper shirt, a poopie diaper, and getting hot and bothered from having my stinky butt patted. Destroyer of worlds I was not.
"Such a grumpy gus! Just for that you can spend a extra hour in your stinky huggies." 17 said. 
"Like hell he will! he's worse then the last one!" 18 said, making me look over at the door to my apparently new room. She was holding her nose and glaring at 17pointing at the changing table with her free hand. "Change his butt, NOW!"
"Awww but sis, he's totally getting off on it! come on!" 17 pleaded. 
"Change his diaper or I'm taking him to the dog pound."
"..She's joking right?" I asked.
"I wish..Finnne be a bitch all your life! Didn't know Gero converted you when you were ridding the cotton pony." 17 snapped, standing up and was about to help me up when he took a kick from 18 that knocked into into the cave wall, leaving a dent. Glaring at him and standing where he was, 18 turned to me and smile. 
"Don't worry little guy, I'm not made at you. this is all on your daddy. ..You are cute..but you'll be cuter when your nott smelly. Auntie is gonna have LOTS of fun with you and had lots of butt plugs to keep you from stinking her room up." she said then walked away leaving me confused and 217 pulling himself out of the wall.
"yeah you better run bitch!" He called after her, getting a middle finger as a response and then she slammed the door.
"...Sooo any chance that didn't just ruin me being viewed as the most dominant member of our happy little family?" he asked turning to me.
"...I mean.."
"Damn it! you only get one chance to imprint with these things! fucking bitch!"
Needless to say, this didn't fill me any sort of confidence that things were gonna get better for me.

the end for now
