"Come on, slowpokes." Glory jokes, running ahead of us. Thorn is easily able to keep up with her, despite his full bladder, but I had decided to stay with Whiff because of my surprising tolerance to his Stench. Coming to think about it, Whiff is a bit... cute? His round tummy is sure a nice sight. And his tush too... It's probably my sexual frustration speaking. I have been blue balled for far too long already. I'll make a point of at least masturbating late tonight...

"We're here." Glory calls from the other side of the hill. Whiff and I catch up and see a beautiful forest town. I was taken aback by how close it looked to a normal town he would see in his home region at first, but as I thought about it, it did somewhat make sense. These pokemon had come from my region and others, so they'd have to know what it looked like. It was a pretty surprising sight...

As we walked into the town, Whiff looked around as if he'd seen this place before. "So you know this place?" I ask. Whiff nods with a frown. "This is the place I spent most of my life after being sent away by my owner, but I didn't think I'd ever be back here..." I was going to ask why, but he didn't seem to want to talk about it, so I left him alone. In fact, that was the first time I saw Whiff sad. I have seen him anxious, desperate, and angry a little earlier, but now he seemed to be feeling... really hurt.

Glory takes us to a tree house and lets us in. "I guess this used to be a dungeon explorer guild headquarters, but since they moved to the center of town, so I got a good deal on it.", she said. Glory was making herself feel at home already. I was a bit more reserved, walking cautiously, unsure if the place was truly abandoned or not. Whiff lied down on his belly, before grunting and rolling on his side. Whiff had not pooped since the previous night and only because I pratically forced him to. He probably tricked me and only did a partial release.

"And we get to stay here?" Thorn says excitedly, walking with his sloshing bladder. A bit of urine left Thorn's slightly aroused private.

Glory nods. All of us spread out and check out the whole place. I finish first and am about to call Whiff... but then I notice Whiff is nowhere to be found. I decided to go look for him and do some sightseeing along the way. This town had everything from shops selling berries and clothes to small healing centers with Audinos, and right there in the center of town, like Glory had said, was a huge explorer's guild building. The place was so huge that I could not help, but feel tempted to become an explorer too; such job must truly pay well!

Right next to the building was Whiff talking to what looked like a guild member: a Krookadile wearing a scarf with an emblem that matched the guild, but what was interesting was he was wearing a diaper. Despite the babyish undergarment, he had such a cocky smile that it made me want to punch him. Surely, someone with that stance, arms crossed leaning on the wall, with a face like that, a disdainful smile, could not be a good person. Actually, he kind of looked like an adult baby drug dealer!

The diaper, however, was very attractive: it looked like it was made of leaves, woven together with thread. He probably got it from that Leavanny store I had passed. The two were talking as if they knew each other. Then again, Whiff did mention that it was his hometown for a while. I was about to leave when I noticed Whiff's posture. He seemed like he wanted to leave. I crept closer to hear what they were saying, already feeling somewhat angry. While walking, I slowed down as I realized that the anger I was feeling had something else mixed in it... I was not sure what was going on, but the scene made me revulsed and prompted a reaction to protect Whiff. I never acted like that before. Finally, I managed to get close enough to hear the conversation.

"Come on, Whiffy. For old times' sake." The Krookodile smiles, with a toothy grin. I shook my head discreetly. That grin was awfully false, as if painted. He was making a damn huge effort at looking friendly and failing.

"No..  Never again." Whiff says in a serious tone that I've never heard from him. I was about to leap in and throw flames at the cocky krocky.

"But you didn't mind them before.", insisted the shady diaper lover.

"Have you already forgotten what you did all those months ago? Anyway, after the incident, I don't need them anymore.", said Whiff, serious. I nodded in support of Whiff, but then I heard Whiff's belly gurgle again. Whiff squeezes his hindlegs together. A normally arousing sight for me, but, this time, I wanted nothing more than taking Whiff out of that scene. But I had to be patient. What if I was misunderstanding something? I would embarrass Whiff if that were the case.

"Really? Then why don't we test that, shall we? I propose a holding contest. We both eat a ton of berries, and in the morning, whichever one of us messes loses. I even got a bunch of those berries you just loved to eat before. What do you say?", asks the diapered poké.

Whiff seems to think about it for a bit.

"And what do you want if I lose?", Whiff asks.

"Simple. For you to wear diapers like when we were kids.", was the response.

"And if I win?"

"I'll give you what you always wanted: a spot in the guild. Your friends can even join."

"...Fine." Whiff sighs. Whiff's face of resignation is heart-breaking. It was like was doing something as humiliating as it was necessary.

"Great. I meet you at the old guild headquarters in an hour.", said the Krookodile.

The Krookodile walks away, beaming ear to ear. Whiff turns around and spots me.

"Ooh, hey Mercury. How much of that did you hear?", asks Whiff.

"Just the end.", I lied, then asked, hiding my anger: "Who was he?"

Whiff rubs the back of his head with his paw.

"His name is Krag. He and I were friends for a while. It wasn't until Guild tryouts that we became rivals. There was only one spot, and I was a shoe-in to get it, so Krag fed me a bunch of Pecha berries before the final test, and I.... messed myself in front of the judges and a whole crowd of people. What's worse is I was wearing a diaper at the time." 

"So those Pecha berries... they're the 'berries' he wants you to eat for the contest?"

Whiff nods, "They gave me extremely soft poop which is a lot harder for me to hold."

"Well, would you like me to help you?", I asked, now starting to feel aroused. I was a bit ashamed of my body's reaction, but Whiff, even though he noticed my member coming out of the sheath, didn't seem to mind. Whiff just chuckled and smiled sincerely.

"Would you?", he asked.

"Sure. What are friends for?", I said back.

"Oh, thank you." He gives me a huge hug. He can't help farting a bit, though...

"Alright. Alright. Come on. We gotta get back."

Whiff and I head back to the tree house, where Krag was waiting, a huge basket of berries in tow. I suggest Whiff to relieve himself before the challenge. He reluctantly agrees, excuses himself and goes into an alley in the city. He waits until the movement is slow and the coast is clear, before sitting on a trash can and filling it. After that, he goes back to where the challenge will take place.

"Ready?" Krag smiles. Whiffy nods. Krag sits the berries between them and the two of them start eating. I head over to Thorn and explain the whole thing to him.

"And you want me to use my vines to hold his poop back until you can get this Krag guy to poop himself?" Thorn seemed unconvinced, whispering.

"Pretty much."

"And you're sure this is going to work?"

"Positive."

Thorn sighs. "Fine. I'll help."

At night, Thorn and I pretended to be asleep. Whiff and Krag are tossing and turning due to the load of poop trapped within their bowels. Whiff is straining particularly bad and might have an accident. But then Thorn leaves his spot, walking towards Whiff. Thorn stops on his tracks, clenches his muscles, but can't avoid releasing a bit of urine on the wooden floor. The sound made Whiff grimace. He probably had a full bladder too. Thorn resumed walking, dripping from his erection. He used a vine to block Whiff's anus, keeping the poop from coming out. Meanwhile, I walked towards Krag. I had a semi-boner looking at Krag, knowing what I was going to do. My task was to make Krag soil himself without waking him up.

	Thankfully, Krag was lying down with his full belly facing up. I started by gently kneading it, pressing softly. Krag was fast asleep still; those berries digest slowly, causing a long, peaceful slumber. So I could work harder. I started to knead the belly harder, making it groan. It felt squishy. "He is certainly holding a lot already", I thought. He continued, causing Krag to stir a little. I stopped my movements, waited a while, then continued. I tried to make it a relaxing massage, to both keep Krag asleep and encourage his gurgling bowels to move. Krag seems to chuckle a bit, brushing his paw against his belly as if I was tickling him. He seemed to be a bit ticklish. I try rubbing again but he rolls onto his side. I got a fine view of his tush. I had not come since I appeared in this world and the sexual desire was growing steady, but I had a task at hand.

	I didn't want to wake Krag up so I decided to try something different. I walk over to the back of his diaper and carefully pull down the diaper, showing off his clenched buttcheeks. They looked dreamy and I ran my paw on it, feeling my penis getting erect. I didn't regard myself as gay, but it was probably my pokémon body being desperate for action, willing to accept a man for that... I softly widen them to reveal his strained anus. I realized that I was leaking pre and panting silently. He most have been holding a lot if it was that tired already. I softly start to put my finger up his anus and wiggle a bit. His own penis began to react, coming out a bit. Then I slowly start sticking my other fingers in one at a time, until I was now fisting him, widening his anus enough for his poop to start to come out. I wait till his poop was out enough that he couldn't hold it back. For all the berries he had ate, the poop was quite hard. I watched it slowly slide out his now widened anus, thanks to me holding it open. It was staining my paw. The smell was pretty nice, which is odd. Different species seem to have different-smelling waste.
	
	The poop lands in the makeshift diaper with a squelch. Now that the floodgates were open, the poop came out quicker as I move my paws from the splash zone, so to speak, quickly putting the diaper back on it's original position. Watching the diaper quickly inflate from all the poop was mesmerizing, causing me to have a full boner now. I did say I wanted to finally masturbate tonight so I slowly start to rub my boner but I decide to have some fun. I walk around to the front of the diaper where Krag was also at a full boner. I start to slowly rub my boner against the tent, simultaneously simulating both our cocks. It tingled so good. My sex drive had increased ever since I evolved from cyndaquil to  quilava. After a few minutes, when I felt that I was close to climax, I stick the cock into the inside of his diaper and climax onto his cock as he climaxes as well. I let out a surprising huge amount, causing the entire front of his diaper to become soaked. I smile as I look at my work and run back to bed. "Finally!", I thought.
	
   The next morning, Thorn wakes Whiff up early so he can pull out the vine without causing the mudslide to come out. Whiff groans a bit as the intense pressure pushes against his anus. He crosses his legs a bit as he starts to drip pee himself, causing Thorn's erection to strengthen a bit at the sight of Whiff pee problem. Thorn has some immense willpower, however, and he completely ignores his own erection, even though it looked desperate to release. Perhaps because he is still a bulbasaur and so he does not have strong needs like I do. Whiff slowly walks over to Krag, who had a extremely saggy diaper. Whiff wondered what was that. Didn't smell like urine. Kreg wakes up...
   
"I guess you win, Whiffy. As soon as I get changed and get back to the guild, I'll get you all registered." Krag say in a defeated tone.

Whiff smiles a bit, but his relaxing causes the load he was holding to start to come out, causing him to sit down and cross his legs hard. He whined. All that pressure was making his morning boner to feel much harder and tingly. I was starting to realize how raunchy pokémon can be when away from human influence...

"Hhey, Krag. Ccan I have a diaper? II don't think I'm going to be able to make it outside." Whiff whimpers a bit.

Krag laughs a bit. "Only if you let me change you afterwards."

Whiff blushes but nods. They seemed to be getting along, but I was still distrustful of Kreg. He was really smuggy in the previous day and every time I remembered that, I felt an urge to punch him. At least, filling his diaper with my seed was a good enough revenge. I chuckled at it, but something striked me: I had taken advantage of someone in their sleep. Is not that really wrong? When I started having these kinds of ideas, I shrugged off the moral aspect because now I'm a pokémon. But am I losing my humanity?

Krag quickly puts a diaper on Whiff just as the floodgates open and Whiff lets out a huge load into the diaper, causing me to bone again. I ignore it. My inner turmoil was keeping me from enjoying the feelings that my body was giving. All males in the room were hard and ready, except Kreg: Thorn because Whiff has to pee, Whiff because he was holding his poop a while ago, and I, because of watching Whiff poop. Whiff shakes a bit at the sheer amount of poop coming out of him.

"Yyou planned this, didn't you?" Whiff looks accusingly at Krag.

"Hey, I knew you wouldn't be able to hold it for too long so I came prepared. I did used to live here after all. Anyway, I highly doubt your friends mind watching this occur.", says Kreg, looking at my erection.

I felt really dirty all of sudden for enjoying Whiff's suffering. Whiff looks at me, almost in tears and I come over to comfort him a bit. "Hey, this is a one time thing. I highly doubt this will happen again." I smile, containing my anger at Kreg. 

Whiff's finishes filling the diaper, which was surprisingly not as full as Krag's and the two changed out of their diaper, Krag now wearing a clean new diaper. "I'll see you guys in a bit with your badges." Krag leaves.

Whiff seemed happy he was finally in a guild but at the same time hurt that he had to break his own promise not to wear a diaper. I sat next to him, rubbing his back a bit, something I used to do to my pokemon that I hope would work on him. He lets out a purr. "Thanks..." 

Now that we were going to be in a guild, we might be one step closer to saving Thorn's friend. But I also needed to care for something else... "Guys, I have a honest question.", I said. Thorn and Whiff looked at me. I sat, legs spread, showing my boner. "Is it fine if I'm aroused all the time by you guys'... 'potty habits'? I feel really bad because of it. I just got aroused when seeing Whiff using his diaper." Whiff seemed confused, but Thorn seemed to be much calmer. "Don't worry", he said, "We can't control our arousal, but we can control our actions. You felt aroused, but you comforted Whiff, instead of making him more uncomfortable. You are not being a bad person, you just have urges like any of us. It's with your actions that you should worry."

Thorn is really wise. What he said made sense. But I was afraid of being overwhelmed by my pokémon urges if I evolve again. Fact is: as a quilava, I am feeling more daring, more hot-headed and I feel that my willpower has decreased...
