The sound of TreBors bed room door slamming shut seemed to echo like thunder in the teen stallions ears. his breath caught in his chest as he stood waiting to see if anyone had heard it. As he huddled clutching the freshly delivered package he had just snatched from the postdogs paws the white colt sighed long brown girly locks falling over his muzzle as slowly relaxed sure he had not been caught.

His Gaze drifted down to the white plastic package he was clutching to his chest heart picking up again in excitement for what lay inside.Ever since his little sister had entered their family the teen had been jealous, sure he knew it was stupid but the attention all the love that use to just be his. He blushed, Then for some reason even as she got into Training pants the stallion had been drawn to her old diapers, he wanted that baby attention she had gotten. Carrying his light burden over to the bed his door shifted behind him a little, lock forgotten. Tearing it open the scent of baby-powder and disposable diapers filled the room just like when his parents changed his sisters. Lifting a diaper from the pack the colt almost stroked the plastic shell of the garments he had shamefully been longing for for years, even when his sisters wouldn't fit he would sneak them trying to wear the tiny undersized diapers on his clearly to big bottom, but now...With a sight he laid back falling onto his bed still clutching the diaper in one hand as he desperately striped with the other.

Laying naked the stallion trembled man hood coming to attention as he raised his ass and threaded his tail through feeling the purple cushion slowly hugging his cheeks like a pillow as he laid back down and brought it up and over his bulging front taping it closed with a moan. He could feel his stallion hood sliding and leaking against the cushy insides of his new diapers, "His" the thought caused his stallion-hood to jerk even as he winced at a grumble from his tummy. He had been holding off for this moment as to not waste his diapers and he wanted to experience them to their fullest.

Rolling off the bed TreBor felt his gut clenching even as he stood crinkling to the end of his bed diaper swaying on his ass as he prepared to do his dirty deed Squatting like a toddler with his back side to the door as he felt the mess inside him shift down ward towards his waiting diapers. Mean while standing by the door now open a crack little foal Elizabeth was wondering why her Brother was in his room in diapers. Even she hadn't worn those baby garments for a year, As she watched the back side of his diaper slowly expanded out drooping the stinky smell of a poopy filling the room as her "big" brother emptied himself the diaper sagging further as with a sigh and a his he wet himself. With a gasp she fled to find mommy, now she understood Big brother needed diapers cause he was clearly still a baby, only babys still had accidents and he needed mommy to come and change his stinky diaper.

TreBor grunted feeling the back of his diaper expand with mess as he unloaded the contents of his stomach into them, log after log snaked its way out to settle into the drooping brown diaper as it hugged his bottom holding the warm muddy stink against his back side. Even as his rear emptied the colt felt a twinge in the front , with no hesitancy he let loose emptying his bladder like a hose coating the front in a warm soaked layer of piss the entire diaper sagging on his hips as he moaned blushing at how much he enjoyed the mushy warm feeling of his full diapers. Standing slightly from his squat he glanced back over his shoulder brushing his hair aside as he admired the lump now settled into the back of his baby pants.The thought of flatting that lump by babyishly plopping down entered his mind but before he could the door to his room swung open his mother standing there jaw slack as she saw her son standing bottom facing her in a full messy diaper. "TREBOR!"

"What are you doing!" The colt stood petrified frozen as his mothers eyes looked him over muzzle moving to a frown of disapproval. "When your sister came and told me you needed a diaper change i thought she was playing some kind of game with you like house or was trying to cover for having her own little accident, but when she insisted you were making a mess in your room I felt i needed to check on you, Clearly you have some explaining to do." Stammering TreBor didn't make a sound the only response a blush on his cheeks one that would repeat as time went by and he was mad the official baby brother of the Dnalget family.
