It was almost nighttime by time we made it out of the forest so after the hugfest, we decided to go find a place to camp. Thorn was dripping the whole time and sometimes took pauses, asking for some time to get himself under control again. It was starting to get annoying, having someone constantly indulging in their fetish around me. Not only, that constant arousal could begin to hurt his penis at some point. It was worrying me... Glory took us to a little grotto with a small lake. While Glory got some moss for some beds, Thorn and I collected some water for later, much for Thorn torturous fun. He even drank some of it. I took the opportunity to come from behind him and tickle his behind, causing him to lose two solid spurts. "Stop it!", he yipped. I did stop, but that would, at least, empty him just enough for him to stop dripping and to soften his erection. I then said: "I'll do it again when you least expect it, unless you tell me how you tell me how you know I was human. And how you knew Glory's fetish."
"The reason I knew Glory's kink was the way her fur, especially her tail fur sat. As for you, your mannerisms show off your humanity." His explanation seemed sound but I still felt that he was hiding something.
Thorn yawns. "Welp. I am going to sleep. We can talk more in the morning." I wanted to ask him more questions. Did he know who I was? Could he help with my amnesia? Could he hold his pee while sleeping?
But by time I turned around, Thorn was already laying in his bed. Since I didn't want to disturb him, I just went to my own improvised bed and laid down. Thorn and Glory fell to sleep almost immediately but I laid there for a bit, thinking. After a while though, I finally fell to sleep and drifted off to dreamland, to the sound of Thorn dripping occasionally.
In my dream, I was a human again. I was with a Meganium that seemed to have to go bad. The Meganium seemed familiar to me but I couldn't quite put my finger on it. "Are you alright, Master?" The Meganium says. Master? Suddenly, a flash of memory hit me. He was one of my pokemon that I always forced to poop and pee themselves, although something wasn't quite right. I then noticed I had neglected my own urges that night and needed to go both pee and poop too. Normally, he would a least try to make it to the bathroom. This Meganium seemed to not care about holding, dutifully holding the liquid and the solids in. From behind, I could see him crowning. I decided to play along until I figured out what was going on.
"So you want me to make you poop and pee?", I asked. The Meganium nods. "Could you at least show me your true form?", I asked, noticing something going on. The Meganium looks at me for a few seconds. "Very good." The Meganium transforms into a Cressilia. "Most pokemon don't see through my disguise so quickly." "What are you doing here?", I asked. The Cressilia smiles. "Giving you a good dream, of course."
"Then why are you personally in my dream?", I insisted. The Cressilia gives me a hard stare. "You wanted to know about your past, right? Well, I'm helping you. My master says not to get involved but I am a kind legendary."
Master? What did he mean? 
"Alright. Do you actually have to go?", I asked.
"It's your dream. You tell me.", Cressilia answered. I looked at the Legendary up and down. I wanted to make him go but I felt like this was a trap. "No. I don't want you to have to go." It smiles. "Good answer." Its face distorts into a wicked smile. Suddenly, I could feel pressure in my bladder and intestines. I try to just let it out but my body seems to be fighting against me. "You said you didn't want me to hold. You said nothing about you." The pressure inside my body kept growing steadily and it was beginning to hurt. I looked down and noticed that my belly was inflating somewhat. Never I had felt so full...
I try again to force myself to go but all I could do is leak a little. "I control your dreams just as much as you can and my master wants me to stall you as long as I can. You are the key to everything.", said the legendary in front of me. My urine flow halted. I had to apply immense strength to get it going again. Never I had thought that peeing would be an exhausting task. I gave up, for the time being. My poop was not moving. It felt like stone.
"So that was a trick question?", I asked. He set me up. "Yep. Although your answer did lessen your fate. See, if you did want me to go, I would have transferred my desperation to you." Coming to think about it, that would be kind of hot if I was Thorn.
Our minds seemed to be connected. Suddenly, I had an idea that came out of nowhere. "Really? Then I can transfer my desperation to you.", I said. I think of Cresselia having to go and I see Cresselia seeming to fight me, shaking his head, as if trying to break the interference I managed to actually make. I didn't expect that to work, but I was glad it did! I pounce on Cresselia and start to try to make him mess himself. Since he was a Legendary, this was no easy feat. I saw his belly growing just like mine.
They smile again, eyes red as blood. "Oh, you want me to pee and poop?" He does a reversal and pins me. I suddenly feel a warm sensation on my legs that was slowly moving up. Was they..? I look down. They were. They were peeing on me. The urine was musky and so warm. It only made my own urge get stronger and more bothersome. "You were OK with your little friend peeing on you. I'm just doing the same.", he said. I suddenly realized what was coming and started to struggle. "Nuh uh uh. No moving." I suddenly couldn't move as Cresselia slowly gets off me and aims his ass at me. I was going to be shat on! I profoundly regretted transferring my desperation to him! He lets out a few long toots before a turd starts to peek out. All I could do is watch as it slowly starts to come out his ass. I felt a tug as vine pull me out from under the poop fire line. A familiar face looks down at me. "Hey, Mercury." Thorn says quietly. I was able to move again. I look over as Cresselia continues pooping. A huge pile starts to form where I was. I was relieved but also a little turned on by the Cresselia's pooping. I got a half-chub and those pokémon mating instincts began coming up again. I licked my lips a little and my hindlegs quivered... "Come on. Let's get you out of here.", said Thorn.
I wake up to Glory and Thorn looking down at me with concern.
Unlike most dream where you just forget, I could remember all that happened. What if I feel asleep again? Would they be back? Thorn see my concern and sighs. "Come on. I have an old friend that could help.", said Thorn. "What?" was all  I could muster. Glory gives me a Chesto berry and I am able to fully wake up. Those berries can't be totally healthy, considering I just felt too awake to sleep now. Insomniac, even. "It's a half day's walk from here. If we leave now, we'll get there  by lunch.", said Thorn, who gave me a reassuring smile but I still didn't understand anything of what happened. Thorn invaded my dream. Was that really Thorn or was that a manifestation of my own unconscious? Further... that dream could perhaps have just been a wet dream, due to me not having orgasms since I arrived this world. And who was this 'master' Cresselia was referring to and what did this have to do with me? "Calm down." Thorn put a paw on my shoulder. "We'll figure this out together." What the actual...? Thorn read my mind, did he not?
 The three of us were ready to go by daybreak. We had enough berries and water for the trip. "Ready?", Thorn asks, his hindlegs soaked after wetting the improvised bed that night, still concerned about earlier. I nod, interested in where we were going. We set off to Thorn's friend, hopefully leaving our problem behind.
 Meanwhile, on top of a mountain, Cresselia stands in front of a pokemon. "I failed, Master." The pokemon looks at Cresselia with disdain. "Then you are of no more use to me." The pokemon does something and Cresselia's eyes change back to their normal color. "Wha? What happened?" The pokemon teleports Cresselia back to where it found them. "I guess I'll need to take a different approach to this. That human has no idea of what I have planned." The pokemon goes to get plan B.
