The pain and pressure was getting stronger, as I could feel a bit of poop wanting to be out of my body. I continued holding it in as it pressed against my already full bladder. I knew what it was I planed to do, ever since I was told to go upstairs, and then get ready for bed. I knew I was going to poopy on a plushie, while I brushed my teeth. Not missing my fang teeth, as I did a very thorough job brushing them all. I laid looking at the ceiling on the top bunk, just staring at it, as I knew I would soon crawl down, and then go to my closet. I had a brand new Stitch 626 in there, which I was thinking about messing up. I also had a small Oopsy Bear in there, which was only slightly stained. I laid there, also holding in a large bladder.
“Denny, must you go to the bathroom?” my mommy had asked.

“No mom, I was just itching my thingy.” I told her.
It was very difficult doing that the whole day, but I was determined that I was going to have a full day’s bladder saved up, to pee on something later. I was starting to regret it though, as my bladder pressed against my intestinal track. 
Pretty soon though, I would have to move, to go at least someplace. Either to the bathroom, or into my closet. Working down the ladder was a challenge, as my bladder hurt me with every step. What step?, my first step failed, as I felt my bladder want to give way. On my second try, I made the first step, of the ladder down the side of my bunk-bed. 
Droplets escaped my body, as I placed both foot-paws on that step, and then stood there for a little while. I pressed myself to take another step down, and as I did, I lost a few droplets again. I stood there, with my paws still on my bed, trying to hold in my pee. I had just three steps to go, but it might as well have been twelve, as my bladder and intestines were causing so much pain. My bladder was the larger factor though.

I had three steps to go, them three steps were going to be very difficult. I pressed to go down another step, feeling a mix of pain and pressure as I tried. A full squirt, squirted into my underpants, as I tried, unable to hold it back. I also failed to finish taking that step as well. I was now crying a little, as I tried a second time to take that step… this time barely making that step, as I hung on the ladder for a little while.
“Come on Denny, you can make this.” I whispered to myself.
“Two more steps.”
I looked down, and them steps seemed like the hardest ones.
Why not just jump? I thought to myself, as this wasn’t a good idea.
If I jumped, I would make a thud noise, which someone would for sure hear. I pressed hard to make the second last step, and nearly missed it… as usual. I looked just like Taichi on that step, as I just barely stabilized myself… failing to make that step, after all that effort. And then I tried again, succeeding this time.

I hung on the side of the bed for awhile, heart thumping in my chest, as I knew I had one more step, and then to the floor. I had something else to think about, as I was trying so hard to sneak to the closet. My peepee was all hard and stuff in my underwear.
“This feels kind of funny.” I whispered, as I held on with my left paw, and then felt at my peepee with my right.

Why I did this, I don’t know, maybe just to confirm, that it was indeed erect? I stood there, soon holding on with both paws again, as my bladder was bothering me even more. I wanted to step down, as I only had to get to the floor after that, but could I make it? Was there a wet spot on the carpet already?
“Oh gawd, I really need to press to get down there.” I whispered, as I pressed to move my right footpaw down another step. Droplets escaped again… but this time, I was slightly relieved… as it wasn’t a full squirt of piss. One more step, to the floor. I pressed very hard, trying to keep my legs tightly against myself, at the same time, as taking this step. This step was indeed the biggest I had to take, as a full squirt escaped my body. I was glad though, when I felt my footpaw his the carpet, even though, it had a damp spot on it. I was even more relieved, when I got my left footpaw on the floor, joining my right footpaw. I stood there for a moment, in a damp spot, from my underwear, now dripping with pee. I stood there for a little while, holding on to the ladder with both paws. I curled up my toes tightly, and then let go, as I let my footpaws feel the carpet better. Although the carpet was a little damp with my pee, it still felt nice and soft. Next would be making it to my closet. At least, I had only very few obstacles on my way, to get there. But then when I got to my closet, I wondered if it was such a good idea, to actually use it for this reason. I could always sneak downstairs,  and then maybe pee on one of Miles’s plushies… hell, Tails wasn’t even around just now anyways.
“No. I care too much about Tails to do that to one of his plushies.”
I said in a whisper. I snuck into my closet, and then had a look around. Gawds, why? All of my plushies were on the shelves above my reach. There wasn’t a plushie on the floor of the closet at all. This posed a new challenge. I would have to find a way to get at my plushies. I walked across my room, fast at first, but as my bladder filled further, it caused me to slow down. I made my chair, and then grabbed a-hold of it. I looked up from where I was standing, at a poster of favorite celebrity, Knuckles the Echidna of the floating island. I liked Knuckles so much, I believe I would let him do anything to me, that he wanted to do. And Miles knew Knuckles. Actually met him.
“Envious? Was that the correct word for it?” I whispered, as I carried the chair toward the closet. I walked in, and then set it down. It was amazingly easy, considering my bladder was so full.
Climbing onto the chair, now that was a bit difficult. As I moved my right footpaw up onto the chair, I ended up letting go of a squirt of pee. I then grabbed at my crotch with my right paw, and then did a little leap with my left footpaw, to get up onto the chair.
My bladder hurting. I stood there looking at my plushies, my right paw firmly on my crotch. As I looked over the shelf, seeing all my plushies actually fit up here. Suddenly as I was holding my crotch tightly with my right paw, my intestinal track started kicking it up some.
“Shit, just hang on.” I was sweating. And tears started rolling down my face, as I held onto the shelf with my left paw. I could easily fit up there with my plushies, but I wasn’t sure the shelf would actually handle my weight. Weight? Only being eight-years-old, and even slightly thin, I didn’t weigh all that much. I reached out far with my left paw, at my Grumpy Bear plush. I pulled him onto the floor. I was standing without extra support at this point, as I thought about getting another plush to use as a potty.
“I could always pee on my Tigger, and then poop on Grumpy’s cloud.” I said aloud, as I had closed my closet, so people wouldn’t hear me that well anyways.

I don’t know what came over me, as I suddenly found myself shoving as many plushies onto the floor as I could. And then I started to step off of the chair. This proved to be one hell of a challenge, as my bladder hurt really badly.
“Come on, you can do this Denny.” I encouraged myself, as I stepped off of the chair. But at I did, I squirted pee some, as I made a small puddle on the chair. But I made the floor, as I was now looking through my plushies, that I shoved off of the shelf. It was a good thing, that I had a walk in closet, as I didn’t need to get rid of the chair. I kicked at my plushies, kicking them further back in the closet, so that I could go back there, and then join them. I had to pick up my Grumpy though, as he was a little too big to just kick back into the closet. I carried my Tigger back there too, as my bladder let out a few more drops. Even with my right paw on my peepee, it was still not enough, to hold back everything I had in my bladder. I set out Tigger over top a few other plushies, and them mounted Grumpy Bear. I sat there for a little while, wondering if I was going to pee on him. My peepee was still all stiffy and stuff, as I grabbed Tigger, and then gave him a cuddle.
“I think I may just pee on you, mah-buddy.” I said, as I gave myself room under my Grumpy. I placed Tigger on his back, so that I could pee all over his chest and stomach. I was over Grumpy’s stomach. Now I was suddenly nervous though, would or could I poop first, without losing much of my bladder? Did I want to do it that way, or just leave my overly full bladder out on Tigger? I suddenly opened up, and then just peed. I peed all over Tigger’s face, paws, stomach, chest. I kept peeing and peeing. It seemed like I should have stopped peeing long ago, but I just kept peeing. My bladder seemed to have relief in it, as it did feel like it emptied for me. But then I just kept peeing anyways, it felt good too. But for some reason, I suddenly felt warm and wet. This seemed to make no sense, as suddenly my eyes opened. I still was on the top bunk of my bed. I was completely soaked, having emptied my bladder all over my bed. My gut still hurt, as I still had to poop. I took a look around. My bed was so soaked, that some of my pee was leaking down to the lower bunk. I got down from my bed, pulling off my covers as I went. I dumped them on my floor. And then, I collected them up, and then headed downstairs. I went all the way to the basement, to the washer and drier. I started my wash, as I soon headed back to my room, on the second floor.
I hadn’t released what was in my intestines, but my bladder was pretty much empty. I went back to my room, and then went to my closet. My plushies were scattered around the floor of my closet, just as I remembered. In my dream, someone had placed them on a shelf, that’s less then half the size from my dream. Hell, there’s hardly enough room up there to placed my eight to 12 inch plushies up there. Grumpy was laying on the floor, with hard clumps of poop on him. No one had cleaned him, since the last time I had pooped on him. I was so excited, I could pee, if I had to go that is. I went to my Grumpy, and then hovered my ass over him. I hesitated though, as I stayed crouched down doing nothing for a little while.

“Hm. That’s my Grumpy, don’t complain, as I add more mess to you.” I said aloud, as I pressed some, but not really hard. I wanted the feel of poop coming from my anus, as I also masturbated. Something some people might not think I did, being the young fox which I am. I masturbated a little faster, as I considered pooping on something else. I let out a clump of poop, and then pressed to hold in the rest. I moved over to a Stitch I had laying on the floor, and then hovered over him. I pressed trying to poop just another piece, while I masturbated my penis at the same time. I groaned as I masturbated, it really felt good, as I pressed some to poop. I felt a piece slip out, and then I pressed to let out another one, as I masturbated faster, feeling the poop slowly escaping from my body. I felt another clump leave my body, as I masturbated faster, feeling orgasm working through my body. It really felt good, as I pressed out another piece, this one felling off the side of Stitch.
I moved toward his neck slightly, and then pressed to poop a little more, as I continued masturbating. My orgasm peaked, and then peaked again right after, as I didn’t spit any cum at first. There was however precum hanging off the tip of my penis, as I pressed hard to poop some more. I closed my eyes for a moment, and then opened them again, my orgasm peaked a fourth and fifth time, before I finally came my load. I spit it all over Stitch’s face, as I spit like eight times. I soon walked back out of my closet, and then went to bed. Mom would probably find my things in the wash in the morning, and switch my wash for me. I fell asleep on the bottom bunk, naked. I just didn’t feel like placing anything on.
