The next day Beast Boy ordered disposable pullups from a site online. Luckily his smaller size was easy to find. They were delivered in less than a day later, Beast boy had a lot more accidents in that time, and was surprised to be looking forward to them so much. When they did arrive, they did get suspicious looks from the other titans, but Beast Boy just awkwardly explained it away as nothing but some clothes he bought. He wasn't sure his lie was believed though, he did say it pretty clumsily. No one bothered to question further though, and Beast Boy ran to his room with the protection he'd been waiting for. He opened the pack, and curious, took off his pants, and underwear, and slid a pair on. He looked at himself, a young teenager wearing a diaper, and sighed sadly wondering if it really had come to this. He pulled his pants back on, and happily saw they didn't show very much at all. It looked totally normal, but as he lifted the shirt portion of his suit, he did see the tops of the pullups showing. Paranoid of the others discovering what he was secretly wearing, he pulled his pants back off, and slid on a pair of his briefs over them, before pulling his pants pack on. That seemed to do a good enough job covering his secret, as only the top of his underwear now showed. He walked around a bit, and noticed that it did feel a little more bulky than before, but slight discomfort was a small price to pay, he thought,so that he could keep his embarrassing problem a secret. As the day went on however, all his misgivings about his "special underwear" slowly disappeared when he discovered how well they worked. For the many leaks he had become used to dealing with, they absorbed it all, and gave him a chance to get to the bathroom and take care of the rest without needing to constantly change his wet pants and underwear. Also, as an added bonus, they were actually absorbent enough for him to only need one pair all day. The night was a different matter though. While the pullups did absorb a lot, he was just wetting himself way too much at night now for them to be much use. They usually always overflowed, and leaked onto the bed. Not that much though, as he found out, he would just need to order something thicker just for night use, and that would keep his bed, and himself dry at night. Beast Boy slowly started regaining his confidence. Rather than constantly wetting his clothes, and needing to change, he instead had his pullup absorb all it could, and then just throw that away when it got too wet. His laundry, and shame went way down, and despite the fact that he was wearing diapers, he started really feeling more like his old self again. 

 A few days later, Beast Boy suddenly got one of the now rare urges to pee that didn't instantly leak, and not able to ignore those feelings anymore, started towards the bathroom determined to make it and not leak into his pullup at all this time. That would be a nice change for once, to not need a change, he thought. He giggled at his own lame joke, and nearly wet himself right there. He clamped down on his crotch with both hands not believing how bad his bladder control was getting now. He imagined one of his friends telling a joke, he saw himself laughing, and totally flooding his pullup, and leaking everywhere in front of them. He shook the disturbing thought out of his head, and continued walking to the closest bathroom. 

Beast Boy managed to get about halfway there when he heard a voice from behind him. 

"Hey BB, where you going?" 

It was Cyborg. Beast Boy didn't want to be rude to his friend, so he decided to respond. He took his hands off his crotch, and tried to look like he wasn't about to wet himself. 

"I'm just going to the bathroom real quick okay?" he managed.

"Well, I just got that new videogame in. Want to play a couple levels with me real quick?" 

"In a minute man, I just have to go, and.."

"That can wait, it'll only take a couple minutes."

A couple of minutes was too long at this point in his bladder weakness problem, but he didn't want to be mean to his friend.

"Alright... A couple of minutes, no more okay..?

The two went into Cyborg's room. Beast Boy tried his best to stay calm. He thought if he could do that, then he'd surely be fine for a few minutes. As he sat down on the floor next to Cyborg though, he felt his pullup squish uncomfortably under him. He only allowed himself to look worried for a second though, Cyborg was watching him now after all.

"Let's get this game going."

Beast Boy managed a weak smile at that as the game started. He was still going over his shock at what happened just now. He'd wet himself without him knowing about it at some point. Was it right when he felt the urge to pee first, or just recently? Either way it was a scary new thing. What if that became normal eventually? Peeing himself without feeling it. He didn't even want to think about it. 

"Oh, close one BB, but I'll make a comeback."

He'd totally forgotten he was playing a game in his fear fantasies. He made the mistake of taking his mind off his bladder for a second, and felt a leak soak into his pullup.

"Cy, I really need to go man."

"In a minute, I almost beat you."

Beast Boy really needed had to decide right now what was more important to him, being nice to his friend, or wetting himself in front of him. After what felt like an eternity he decided to be a little rude to avoid huge embarrassment later. 
By the time he did decide this though, he could barely hold it in anymore, even though it had only been less than a minute. He put the controller down, and carefully, slowly started to get up again. 

"I'm sorry, but I really g g g gotta g g...." He stammered as he rose. He trailed off only because in the middle of standing, he felt yet another warm leak from in his pans soak in. As he turned away, Cyborg got a devious look in his eyes, unaware to Beast Boy.

"Oh, running out on our game huh..? Then you get one of these."

Just then he leaps up, and grabs Beast Boy's pants getting ready to pull them down.

"CYBORG!! NO!!" Beast Boy yells, but it's too late. In a fraction of a second his pants are on the ground. Cyborg went a little overboard too, and pulled Beast Boy's briefs down with the pants, and now his soggy pullup was exposed to his friend. It only got worse though as the shock, and terror made Beast Boy's weak bladder finally give up as he totally soaked his pullups the rest of the way. Just as he feared they overflowed, and leaked sown his legs and into his clothes on the floor. Unable to hide his humiliation anymore his eyes started welling up as he expected to be teased, what he got was just the opposite though.

"Beast Boy? What's wrong? What are you wearing man..? 

Now there being no more reason to hide it, Beast Boy simply told the truth.

"They're pullups okay..? My bladder's been getting too weak for me to go without them, and if I didn't have them I'd be wetting my pants all the time. There... You going to make fun of me now..?" He said with tears in his eyes.

"Never dude, I'm your friend. I wouldn't have did that if I knew man.."

"Really..?"

"Really dude, but now I feel really bad... Come on, and I'll help you get cleaned up okay..?"

"Okay..."

Beast Boy pulled his now damp underwear and pants back up over his drenched pullup, and the two went to his room.

"What do we do now man?"

"I usually just get a quick shower to clean up, and get some dry clothes..., and a dry pullup."

"Okay dude, don't worry, I'll get all that while you get in the shower."

"Thanks..."

Beast Boy disappeared into the bathroom and stripped off the wet pants, briefs, and now soaked pullups. He was still surprised how much they held up tp leaking. As he got in the shower Cyborg did what he said he'd do, and gathered up a dry pair of pants, underwear, and a new pullup. He looked at it feeling bad that his friend had to wear these now, and felt guilty of how he made him feel about it. He just had no way of knowing though, so he decided there was no reason beating himself up over it too long.

"Okay, I'm done, hand the dry stuff through the door."

Cyborg did as he was told, as he felt the pile being pulled away from him. The seconds went by awkwardly, and Cyborg decided to break it with some conversation.

"Man, I can't believe you kept this a secret for so long, you usually can't keep any secret at all. I think I never noticed because of the way you wear your briefs over the pullup man. That was pretty clever."

Beast Boy gave a weak giggle, "Thanks.."

"BB, I don't like you having to go through this, maybe you can tell Robbin. He has connections in medicine, and maybe he could find a way too cure this for you, huh?"

Beast Boy nearly jumped at the thought, "NO...no...Not yet. Maybe he could help me, but I just want to wait a little longer okay. Just let me build up the courage to ask him, besides, if my accidents get any worse, there'll be no hiding it anyway right..?"

"Right..."

Cyborg knew better than to force Beast Boy to do something big like that, and agreed to keep his secret a secret until he did it on his own.
