I stand in the large oversized crib and wiggle humiliatingly, desperately trying to hold my painfully full bladder, my master made me drink so much water before leaving and now I know why. The diaper rustles with every movement as my client watches my struggle with amusement, my moans of discomfort muffled by the pacifier gag in my mouth, which I suck on, somehow helping to calm me. I whimper slightly in embarrassment and disgust as I feel a warm dampness spread inside my diaper, the white turning a shade of yellow as I piss myself uncontrollably into it, my client smiling happily as he watches my humiliation, my cheeks turning red with embarrassment.

"Good boy. Did you make a mess in your diaper?" Not allowed to talk and unable to while gagged I look at him shamefully and nod.

"It's alright, you are a good boy for going in your diaper, that's where little boys like you go toilet. You are a good boy aren't you?" I nod, I am a good boy, a slight smile crosses my lips, one I hope he doesn't see. 

"Do you want daddy to change you?" I nod, definitely wanting out of my now soggy diaper. I lay down in the crib as the side is lowered and I feel my thick padded underwear open, humiliation fills me as my straining caged cock is now in full view, revealing my true feelings despite all my protests, the whole humiliating and embarrassing position I'm in, forced to piss in diapers turns me on so much, it's a shame I probably won't gain any relief until this ends, whenever that will be. Hopefully not long, being a baby is so humiliating. 

"I see someone enjoyed their diaper. Don't worry, daddy will put you into a nice fresh diaper. I try to hide my face as he puts on a clean diaper, the shame and embarrassment to much for me. I feel an arm wrap around me as he embraces me.

"It's alright baby. No need to feel embarrassed, all babies use diapers, there is nothing wrong with that." He rocks me slightly and I begin to feel strangely comforted. I feel my gag loosen and the pacifier drop out of my mouth, quickly replaced by a large baby bottle full of warm milk, which I hungrily suck on, drinking down my meal, one that tastes slightly strange, a slight aftertaste making me unsure of what I am consuming, but I really don't have any choice, I'm naked except for my diaper and my weak body couldn't fight back against the larger man even if I tried, besides doing so would mean disappointing a client, which would upset my master and lead to me being rightly punished, so I just do as I’m told. 

Finishing the bottle I burp and feel surprisingly tired. My eyes close as I lay in the crib, the side locking back into place like wooden cell bars as I drift off to sleep.

I awake to an uncomfortable pain in my guts, my insides rumbling. Oh no! I need to go to the toilet really bad! I squirm on the floor of the crib and pull myself up unsteadily to my feet, looking around for my client, he isn't here to let me out. I let out a muffled cry from my gagged mouth and pull frantically on the wooden bars of my prison, the feeling inside growing worse with every second. I watch hopefully as my client comes in.

"What's wrong baby? You about to go potty?" Yes I'm about to go potty! I'm about to shit myself! My client just stands calmly and watches as I desperately struggle to hold everything in, my body doing a little dance and groaning, trying to prevent myself from shitting in my diaper. 

I groan defeated, humiliated, embarrassed and disgusted, as I feel the warm sludge explode out of my ass and begin to fill my diaper, tears of shame and disgusted embarrassment fill my eyes as I continue the go in my diaper, unable to stop myself, my bladder emptying as it begins to sag under the weight of my mess. 

"Don't cry baby, daddy will change you." I stand frozen in embarrassment as the crib opens and I'm gently forced to lay down, the warm slime squishing against my ass as I do. 

"Wow that's a stinker. I guess those laxatives worked well." What? So that's why the milk tasted slightly funny. I mumble a complaint.

"Yes you did make a stinky mess but it's all good now." I feel a wet wipe cleaning my butt before a fresh diaper is put on me, ready for me to make messy once again, my cock straining at the thought.

“I have a special treat for being such a good boy.” I turn my head and see his hard cock as it moves towards my, my pacifier removed just before it touches my lips, my mind instinctively allowing it in as I begin to suck on it.

“Let’s a good boy, time for your special dinner.” I move my head back and forth as I work, quickly receiving my meal, one much more delicious than the warm milk I’ve been given as my only food.

“Good boy, eat up your dinner.” I feel his hand gently stroke my head as I lick and suck his cock dry, making sure that I get every drop of my meal. I let out a slight moan of sadness as his cock leaves my mouth, disliking the empty feeling, one thankfully not lasting long as my pacifier gag is placed back in, which I happily suck on.

I feel a soft kiss on my forehead and close my eyes peacefully as I hear the crib close and lock, sealing me safely inside until I next need changing or feeding, my client smiling down at me lovingly.

"This week together is going to be so fun my sweet little baby." A week! I moan into my pacifier as he turns and walks away, my cock straining as I learn that this will he my fate for a whole week, locked in a crib, forced to piss and shit myself in diapers and reduced to a helpless infant. 

"Sweet dreams my little baby boy." With that the light goes out and I'm left alone in the dark to sleep, rest ready for a week of being his baby. 

Epilogue: 

I stretch in my damp diaper having messed myself in the night and fallen to sleep again, I've grown used to the feeling of my soaked diaper now. I hear the door to my bedroom open.

"Here he is. All well rested and ready to go home." I slowly open my eyes and I immediately feel a wave of humiliation as my master stands over me and smiles down with amusement seeing me laying in my wet diaper and sucking on a pacifier.

"It looks like the baby boy wet himself." He smiles down at me, enjoying my pathetic and embarrassing condition.

"Did you enjoy your stay here? Was it fun spending all day in your crib, pissing and shitting yourself like a helpless baby? I bet you did." I feel him undo my diaper, revealing my straining cock, my master smiling in delight.

"Yes you did! Who is my perverted little boy? You are!" I can't help but smile as he praises and humiliates me, it's true I am his perverted little boy.
