Down for tonight’s sleep, but I didn’t want to be. Actually, I had to pee really badly, and my poop was so constipated, it was poking out of my gut… or at least I could feel it with my paws. Laying on a bunk-bed, top bunk, I just wanted to get down. But I did not want Fievel Sr, my daddy finding out I snuck out of bed again. Time went by, as I lay waiting to be sure my daddy was asleep. I was either gonna go to the closet, or hide my poop behind the bed.
Either-way, I was gonna get rid of my poop, and do it someplace I really shouldn’t be doing so. I fell asleep, as I wanted to get up and then do this. I woke, finding that several hours had already passed. I was going on 5:30 in the morning. I only had about an hour, two at the most, to fool around. I got out of the top bunk, and then to the floor. I went over to the closet, and then snuck in. I cringed though, nearly every time the lock made its clicking noises, as I turned the knob. I stepped inside, and then closed the door behind me. I first started looking around for plushies which I might like pooping on. Somehow, without noticing, I kept looking past my daddy. I only noticed him when.
“It’s about time you get in here.” said dad.
“Oh crap, I guess I am caught.” I said.
“Shush, no one knows I am in here.” said dad.
“So then you are just in here, to catch me?” I asked
“Well not really, I am here to join you. And also to teach you some.” said dad.
“Join me?” I asked.
“So what are you pooping on?” asked dad.
“So I can poopy on my favorite plushie?” I asked.
“Shhh, yeah. If Grumpy is your favorite, why not let me join you with this Grumpy Bear?” daddy had a large enough Grumpy. That we could both poop on part of it’s stomach. But I didn’t have to poop on that one.
“I think I am going to poop on this one.” I said, as I placed him underneath me. I pressed pooping some on his cloud. Dad smiled, as he pooped onto the larger version of Grumpy Bear. He was holding his penis like I did. Sorry I failed to mention that. I didn’t want to pee, until it seemed like the correct time for it. From the look of daddy, he was avoiding pissing until later as well. I lost a little bit though, as I squeezed out a large piece of poop. I did it a second time, I grunted and groaned, as I started pooping. My anus felt as though it would split into two, as I cried pooping this piece. Not the kind of crying that I made noise, just lost a bunch of tears, as I cried. My poop felt like it got stuck at one point, as I placed my right paw back there, and then touched my poop. I cried a little more, as I managed to mash a piece, up against part of Grumpy’s cloud. Pooping, while dad actually watched me, and wasn’t saying anything bad about it. I pooped quite a bit, as I left Grumpy Bear dripping on the sides, with a slight bit of diarrhea with constipation mixed. I went toward my dad, as I finished. Daddy didn’t ask me to, I just did it. What was possessing me, I didn’t know, as my goal was to grab my Daddy’s penis, and then start masturbating it… like it did mine. I thought daddy would say something, and he did. But not along the line of what I thought he might say.
“That’s my boy!” he said silently, as I began masturbating my daddy’s penis. Daddy groaned, as I masturbated his penis some. I wondered some, whether or not he might place his penis into me.
“So do you want your sex lesson.” asked Fievel Sr. I was just about to place dad’s penis in my mouth, when he asked that.
“Oh yeah daddy. Please teach me.” I asked, hoping he would place his penis into my anus. Daddy was still sitting on the Grumpy, but with a pile of poop behind him, as he was sitting on Grumpy’s neck.
“So, I’ll tell you what you do, get onto your paws and knees.” said daddy. I did so, and then cringed a little, waiting for it.
“I’m ready daddy, go ahead and then fuck me.” I said. Daddy had a dildo, which he placed lubricant onto.
“First son, I am going to get your body ready for this.”
“Okay dad, just do what needs done.” I said with a smile.
“Well then here I come, brace yourself.” I placed my mousey claws into the carpet, as I felt the dildo on my anus. I soon felt pressure on my anus, as my daddy started pressing the dildo at my hole. It caused a bit of pain, as it penetrated my anus. I groaned a bit, as I felt the dildo go up my anus. I could feel it tickling my insides, as the dildo was just so big. It felt in some ways, that it was somehow touching my penis somehow. I squealed, as I did, I placed my right paw to my face, did so, so fast, I thought I might have caused a mark. I let part of my squeak out on my paw. As I nearly ate my paw, trying to just stay quiet, or at least it nearly felt like it, as I tried so hard and fast to shut myself up. I wanted my dad to shove it in right then, but wasn’t well enough in certain ways, to place it in so many words. Dad was hitting something in my body, which was making me feel really good… my penis felt like it had pee in it or something. It was giving me quivers, as I had some sort of good feeling. Dad slid the dildo out. He then did, did, seemed or felt like his tongue was on my anus. My father wasn’t saying anything for sure, I knew that. If anything, he was saying, “Gruuuu,,, Nnnuuu, MMMmmmmm.” for what reason I decided to, I pressed to poop. Daddy only groaned, as I actually pooped a piece. Dad just went and swallowed my poop. In a way, I couldn’t believe my daddy had just ate my poop. He licked my whole asshole, the whole way around. For something so weird, it turned me on so much. And then dad changed positions, and then pressed his penis against my anus. I merely groaned as he pressed his penis into me. I groaned some more, as daddy pushed his penis in me all the way. 
“That’s it my boy, take my penis.” said dad, as I groaned a bit.
“Yeah, I just hope mommy doesn’t catch us.” I said, as daddy pulled out some, and then shoved back in. I grunted, as it caused some pain. It seemed familiar suddenly for some reason, I don’t exactly know why. It’s almost like as if, we’ve both been here before. My penis was erect, as for some reason, it was turning on my body. Daddy reached his paws around me, and then grabbed my penis with his right paw.
“Psssst, what are you doing in here?” oh shit, was going through my mind. It’s grandpa.
“Papa, this isn’t, ahh.” said Fievel, as he hadn’t an excuse he could actually use.
“That’s alright Son, as your ass could always use it too.” grandpa let little warning, as he pressed his penis against my dad’s anus. Dad groaned some, as grandpa penetrated dad.
“That’s it boys, just keep up what you had been doing. “Said grandpa.
“Eh, I am going to peepee white slimy stuff.” I said from the bottom.
“That’s a boy.” said both grandpa and daddy.
“Eh Nnn.” I groaned out, as now daddy was moving in and out of me, causing grandpa’s penis to move in and out of daddy. Somehow, daddy’s erection in me, didn’t go down, as grandpa shoved his penis into daddy. Daddy groaned in orgasm, as he pressed and pulled his penis in and out of my anus. As he did, it of course caused grandpa’s penis to go in and out of daddy’s anus.
“My papa is so big.” whispered daddy to me, as he kept working on my anus, at the same time as masturbating my penis. I felt my body start dripping, as I tried to say something to daddy, 
“Nnnnn, ehhh, “ but it came out as groans and grunts. Daddy was groaning constantly, as he had sped up his pace. Grandpa had sped up his pace too, as I felt peepee escape my body, before that slimy stuff. I knew it was coming though, as my penis suddenly felt like it was going to release pee or something. It wasn’t pee that was gonna come out though, as it did suddenly come out. Oh and it felt so damn good, as my penis spit that slimy stuff, grownups refer to aw semen. Daddy groaned heavily, as my anus felt as though it got wet, which it did. My anus wouldn’t keep all of my daddy’s cum load.
“I am done, you can relax.” whisper daddy, as I relaxed my body, and then laid down on the floor. Grandpa kept fucking daddy above me, as daddy was half using me for support.
“If you can, slide out, so that I can stop using you for support.” said daddy, as we somehow managed to do just that, without grandpa having to stop. I now was watching grandpa fucking daddy, as I grabbed my legs, and was licking my own anus. Daddy’s cum leaking out had a wonderful taste. Daddy groaned and groaned, as his orgasm may have been over, but Grandpa’s was just nearing its peak. Grandpa was groaning quite a bit now, as he was saying.
“Oh yes son, that’s the way.”
Suddenly, somehow daddy came another load, as grandpa did so too. There was cum leaking from daddy’s anus, as grandpa pulled his penis out. Grandpa smiled, and then looked over at me. I was still licking my sore anus, as the cum leaked out a little more.
“Ya, yes grandpa?” I asked, as he was looking at me.
“Enjoying yourself, grandson?” asked grandpa.
“Am. Can you fuck me, with your larger crotch?” I asked.
“Ahh, I guess you want to see what daddy experienced?” asked grandpa.
“Yeah I do.” I answered.

“Next time, I promise.” said grandpa.
I smiled, as I licked my anus for a few more moments, being sure I got all of daddy’s access cum.
“Well, we need to cleanup.” said daddy. This part of things, I didn’t much like. Having to cleanup the larger pieces of poop. But it didn’t take us really long, with all three of us working on it.

(FIN!)
