"Let's get some yummies!" Mike declared as he tugged at Jeff, the pair giggling and crinkling up a storm as they scampered out of the bedroom. They slowed to a waddle once out in the hall, hand in tiny hand as they looked up in awestruck amazement of how different the familiar surroundings seemed from their shared viewpoint of two and a half feet above the floor. The baby boys eeped at the feel of the cold tile against the soles of their bare little tootsies when they entered the kitchen, needing to combine their miniscule strength just to open the door to the monolith-like fridge. Their eyes lit up and their tummies rumbled upon seeing the leftover chocolate cake on the bottom shelf, their tummies rumbling in time as they studied its luscious frosting and fluffy golden interior. Jeff was just about to ask Mike how they should get it out of the fridge but received his answer when his dad fell to his rounded knees and plunged his pudgy little hand into the confection, cramming a fistful of cake and frosting into his open mouth with no regard for how much chocolate he was getting on his tummy and cheeks and chest.
Inspired by how eagerly Mike fed himself like a real toddler, Jeff hesitated for but a second before following suit - sharing a cheeky grin with his dad before the pair absolutely demolished the cake, alternating between shoveling it into their mouths and smearing one another with chocolate frosting. It was halfway through such a frosting fight when Mike suddenly stopped and laughed like a madman, leaving Jeff confused as to what his dad found so amusing.
"Dere's just as much on you, y'know." Jeff snickered, thinking Mike found the sight of the toddler smeared with chocolate especially adorable.
"Dat's not why I'm waffing." Mike grinned, Jeff following his dad's gaze as it fell from his chubby tummy to the front of his diaper - to the thick bulk of padding between Jeff's pudgy thighs growing yellower by the second. Jeff gasped in realization that he was wetting himself without even realizing it, that he didn't even know he had to go until Mike caught him drenching his Pampers like the baby he'd become. Mike giggled as Jeff went beet-red, watching his son realize - and then, with an adorable grimace - accept the fact that there was nothing he could do to stop the flood.
There was also, he discovered as his tummy rumbled again, nothing he could do to stop what came next. Mike looked on in awe as a whimpering, kneeling Jeff did what instinct demanded - as the seat of his son's diaper began to sag. The father released a whimper of his own as he absently stuck a hand down the front of his diaper, playing with a nub that had grown rock hard as he witnessed his son helplessly mess himself. Soon the seat of Jeff's Pampers stretched heavily against the cool tile beneath him, the kneeling baby letting out a little grunt as he finished his first pants-pooping in over twenty years. Sensing that his son might be in some distress, Mike came back to himself enough to stop playing with his stiffie and lay a tiny reassuring hand on Jeff's shoulder.
"Jeffy?" He peeped. "You okay?"
"...uh-huh." Jeff murmured after a moment, a naughty grin tugging at the corners of his lips as he squirmed just so in his full diaper. "I...um...I kinda get why you wike dese fings so much."
"Weawwy?"
"Yeah! It, um, it sorta feels good to just wet go wike dat." Jeff shyly admitted with a little giggle. "Heeeeee. I made a big poopy in my dipee, daddy!"
"You sure did!" Mike was giddy at seeing Jeff find his own affinity for diapers, at his son - far from being ashamed by the act - beaming with pride at how badly he'd messed himself. It became all the more difficult for Mike to keep from tugging on his weewee when Jeff - finding it too difficult to stand thanks to the new weight in his Pampers - instead opt to crawl away from the fridge, giggling madly as he dragged his stinky little butt across the floor. Wanting to show solidarity in babyhood, Mike fell to his own tiny hands and rounded knees, catching up with Jeff as the giddy boy scooted his way out of the kitchen, dragging his full diaper behind him as he went. "Hey, where ya goin'?"
