The bulge in the front of Ethan's nappy seemed to get bigger and tighter the more I kissed him. The soft disposable nappy under my fingers felt amazing as I squeezed his bum, listening to his whimpers. His face was red and hot, and I could tell how desperate he was to mess as I sucked his tongue.
"You must be desperate, son." I smiled at him.
"So desperate, Dad" he whined. "It's gonna be a big one."
"How do you know?"
"Because I've been holding it in all day. Plus I checked."
"Checked?"
"You know. What you did last time. Put my finger in my botbot and felt around."
I was so proud of him copying me with such a dirty act.
"And from the amount you're farting it sounds like you're desperate to push it out baby boy!"
"Yes Dada."
I went behind him, and tucked in the padding from the back of his nappy in between his bumcheeks. I got on my knees so that my face was right in front of his bum, stroking his thighs from behind.
'Now, son. I think we both know what you need to do now, don't we?'
He whimpered yes.
"Are you nervous son? Thinking about how your warm messy poopoo is going to feel on your sensitive, shaved bum?"
Did I just hear him gasp slightly?
"That's why I shaved you, little boy. I want want to really feel it. I want you to know, truly, that you are my dirty little son, and you're never going to use a toilet again."
"Oh god, yes Daddy."
"Now push."
He squatted slightly, grunting like a little boy.
"That's it, biiiig pushies.'
I heard the slimy crackle of his bum opening, and watched as the pack of his padding pushed out from his bumcheeks. Slowly, his poo left his sweet hole, little by little, until a big steamy poo nestled in the back of his babypants. He sighed, and I felt the front of his nappy tent even more.
"Good boy!!"
I praised him with joy.
"Such a good boy pushing out his poo when Dad tells him to! How does it feel, little boy?"
He caught his breath.
"Really mucky, dada"
I lightly pushed my nose into where his poop pile was sitting, and sniffed hard, exhaling the stink of his piss soaked crotch and his shit-filled nappy, taking it all in.
"Wooh! What a stinky boy!"
"Do I get changies now, Dad?"
I laughed.
"Of course not, baby! You need to get used to sitting in your messies, don't you? Then you'll feel like a real baby. Silly boy!"
He giggled nervously.
"In fact, why don't we have a nice sit down!"
He held both my hands as he slowly and cautiously began to sit on my bedside chair. He stopped for a second, hovering over it, savouring the tension.
"Go on, poopoo boy!" I encouraged.
His full nappy and messy bottom steadily collided with the wooded seat, making a delightful squish.
"Oooooh!" He moaned, feeling his thick warm mess ooze on his smooth bumcheeks.
"Very nice baby boy. You can really feel it, can't you?"
He started rocking back and forth, soaking up every feeling of movement, his warm mushy poopies spreading across his bottom, warming the slick canal of his crack.
He moaned and giggled.
"Ooh dada it's going up my balls!" He squealed excitedly.
"What a lucky boy!"
We spent the next hour and a half playing lots of messy poo games. My favourite was either when we sixty-nined, my cock in his throat, and my nose in his crack (for some reason, the smell of his mess was addictive to me), or bouncing him on my knee while we watched porn. Soon, as promised, we were doing a little photoshoot of his messy nappy. I was positioning him, getting him to lean with his legs open and his arms on the wall, bottom pushed out, exposing the dirty brown legs holes of his nappy where some of my son's poopoo had tried to escape. He was laid down on his back on my floor, holding his knees, his big bugle and slowly-turning-brown pampers on show, smiling at the camera, beaming away without a care in the world. Seeing such a happy boy with such a full, stinking, shitty diaper made my heart flutter. I couldn't have found a better incest son.
We finished taking photos of us sucking eachothers tongues when we asked "Can we make videos at some point too, Daddy?"
"What a good idea, baby boy!" I beamed. "Want Dad to make you a little film star?".
We started getting the big oversized nappy mat ready for his long awaited nappy change. I laid him down softly and kissed him deep.
"Right then, baby boy. Let's see what the damage is!"
I ripped off his tapes and opened his cute little nappy with the lion design on the front to reveal an enormous pooey mess. It was a warm brown, mushy yet thick, like he'd been eating a lot of fruit. The front of the nappy was soaked with his piss and the smell of his shit filled the room. I saw him gingerly lean over to see his shit-covered bum.
"Don't worry, son! I'll take some pretty pictures. Smile!"
He grinned at the camera and put his thumbs up as my phone clicked. I took lots, some of him sucking his thumb, some of him covering his mouth in a mock 'ooh, whoopsie!' moment. His poo had really covered the cheeks and crack of his little bum, like his bottom was painted brown.
"That's right. Very pretty."
I put my hand in and grabbed a big load of his mushy mess, still warm in my hand, feeling it mush between my fingers, and stroking and smearing his bottom with it.
I cooed at him "Such a big poopoo from such a little boy! Who's a stinky boy, huh? Who's a stinky baby?'
He moaned at the feeling of his warm poo rubbing across his bottom, and blushed and giggled at my teasing.
"Come on son, I want you to say it. Who's my stinky little pooey baby?"
Out of sheer desperation, he cried 'Me, Dada!'
"That's right baby!" I growled as I stopped stopped big load of his mess around his cock.
He moaned loudly as he felt his poopy mess ooze over his shaft.
"That's right baby! Poopoos on your little prince parts!!"
"Oh Dad, yesss"
I slowly walked him off, until he stiffened.
"You okay, son?"
"I still need to go, Daddy!!"
"Wee or poo?"
"Both!!"
It's okay baby, you can go. Weewee first."
He grunted as more piss started flowing our if his cock. Within a second, I grabbed his pooey cock and aimed it so the stream of wee made it's way into my mouth. I gulped it down, savouring the warm, deep taste. No sooner than had he started pissing, he pushed, and his puckered little hole pushed out a smaller pile of poo. I rubbed it into his crack once I finished drinking.
I watched him laying there, panting, legs open, cock hard, his bum cheeks, his crack, his shaved balls and cock covered in his poopoo. We both knew what was coming next.
"Dad thinks it's time to clean you up, son."
"Oh god, please daddy. No wipies!"
"What does daddy say about wipies?"
"He doesn't need them."
"Why not, baby boy?"
I watched as precum sprinkled from his cock.
"Daddy has a tongue."
I pushed my face straight into the mass of his poo, licking up and swallowing his shit, slurping it up from his crack and his cheeks. I savoured the stinky taste that I adored the last time I did this to him. His cock and balls weren't neglected either, as my tongue lapped up his mess from there, too. The whole time I could hear him squeal and moan and ask for more. I stopped and looked at him.
"Remembered when we talked about you trying something?"
He gazed at me, shocked. He was remembering a very dirty call we had about a nasty act I wanted him to try.
"We don't have to do it, but does my sweet little son want to try?"
He stopped, considered. Nodded and grinned.
"I am so proud of you baby boy."
With one hand, I jerked off his half clean cock.
"Close your eyes. Stick out your tongue."
He obeyed cutely.
I put my middle and index finger together and slid them into his pooey bottom, feeling the warmth and thick mess filling his ass. I took them out, admiring a little piece of poopoo that was covering my fingers. I wiped them on his pink tongue and watched him grimace slightly and then moan. His tongue slid back in and I watched him savour the taste. I praised him and went back to tasting from his pooey bottom. I was even licking the inside of the nappy itself and saw his hand pick up more poo- he was tasting more!
"That's it, son, keep tasting!"
Our filthy act ended with him covered in both our spunk, with his arse fairly well cleaned by my tongue.
After a bath, we put him back in a clean nappy.
"You seemed to enjoy that a lot, baby boy. Didn't know you were so hungry!"
He blushed and gave me a dirty grin.
"It was so dirty daddy, but I couldn't help it, I just had to."
"Would you like to do that more?"
"Let's keep trying it Daddy. Little by little?"
"Of course, son. We can pace it how you want."
I licked up his shaft and closed the nappy.
We got into bed and snogged for half an hour before he fell asleep with my hand in his nappy. What a dirty little boy, I thought. My own incest son, spending a week in nappies, just for me.
Such a pervy week was to follow our filthy night. My mind danced away at different ideas for naughty, pervy games. It was goi g to be a week to remember!
