Ben Johnson had got up to do a nighttime diaper change of his eight months old baby son Josh after waking to hear the little tyke whimper on the wireless baby monitor. His wife took sleeping pills, so the chore was his. He passed the bedrooms of his other two sons, looked in and smiled when he saw that Ken was sleeping in Fred's bed again, both boys fast asleep with their hands down their pajama pants, no doubt protecting their favorite toys from harm. When he got into the nursery, he discovered an incredibly sodden diaper - it had even leaked onto the bed sheets. That had happened several nights. As he lifted the dripping, bare-skinned baby boy up from behind the bars of his baby bed, he groggily thought that he should remember to buy some diapers with a larger capacity for nighttime. He had a dwindling piss boner, but thought nothing of it as he went naked from the nursery. He preferred to sleep naked, as he got a kick out of stealing a night-time assfuck from his drugged, sleeping wife in the middle of the night, guiltily thinking about his three sons and pretending he was fucking a tight boy hole, and not his wife's ass. He tried not to think too much about those fantasies. He was a good dad. Josh quickly got quiet and cooed as Ben removed the sodden nappy. The boy was starting to get more hair now, but it was so light it was almost white, and soft as silk. His mother's medication made the parents decide to bottle-feed him, unlike his two siblings, who had been breast-fed. They had been afraid he be more prone to illness, but he was a plump, healthy baby boy, his blue eyes glittering happily at most times. He lingered a little longer than he should while washing the pee-moist crotch, and was rewarded with a stiffening little baby hard-on and more happy coos. This caused his own cock to harden again, and he guiltily cast a glance towards the door - what father got turned on by baby stiffies? As he lifted the boy by his legs to wash his perfect baby butt, the little boy suddenly started peeing through his stiffy. The warm, yellow stream hit the boy's face, luckily missing the eyes. A nappy-change pee wasn't unusual, and Ben had read that this was just a reflexive action caused by the slightly cooler air on the crotch. Normally Ben would just cover the spurting spout with the washcloth, but now he just slowly let the legs down as he stared, transfixed on the baby pissing itself in the face. His cock was rock hard and starting to leak pre-cum. The boy blinked and gaped, getting his own pee in his mouth, and coughed daintily before swallowing. I'm a pedo, he thought. A sick one. I actually think baby boys drinking piss is hot. The stream dwindled, and now the boy was peeing himself profusely on the naked baby chest and stomach. How could he pee so much after wetting the nappy till it leaked? Was he sick? A pang of father's worry hit him, and caused his cock to lose its hardness a bit. Or... no, it couldn't be..? Just a few days ago he had passed the two older boys running giggling out of the baby's room just as he went in to discover just such a soaked diaper. Could the boys... could they be peeing in their baby brother's diaper? He thought back to Saturday two weeks ago... He was sitting in his favorite armchair, watching sports and having a beer. Several beers, in fact. He had the sleeping baby in his lap. After a while, the beer wanted out, but the game was in its last phase, and he didn't want to get up. He realized his cock was hard, with the warmth of the baby's butt on top of it. Maybe... His wife was out shopping, and the boys were upstairs playing noisily... He really had to go to the toilet now, his bladder was protesting, he just had to piss at least a little! He got his cock out, glancing at the screen to not miss anything, and put it inside the baby's diaper through the leg hole. It was warm and damp, and then his cock head met resistance. The baby had a baby stiffie! Ben had always been able to piss from a hard cock, and had peed himself in the shower as long as he could remember. Now with a moan he let a little urine out. He was actually pissing in his baby son's diaper and on his baby son's boner! He tried to stop, but the bliss of relieving his bladder - and in retrospect, his horniness - blinded his reason, and soon he just let it rip. A hard, yellow stream of beer piss bathed the baby crotch inside the diaper, which was designed for minute amounts of baby boy pee and not a flood of daddy piss. His son woke and looked up at him, starting to giggle at his daddy's weird face and the tickly wet piss massage his baby boner was getting. The piss the diaper couldn't cope with ran out the leg hole along his rock hard cock and made Ben's shorts warm and wet. As the last piss ran out, he involuntarily flexed his buttocks, massaging his cockhead with his baby son's two-inch hard pissy pee-pee. Then he amazingly felt the baby cock slide inside his foreskin, sending his mind into another place. His whole body tensed in delight, and he realized he was going to cum. His butt muscles started to shake, making the baby stiffy vibrate against his cock head inside the foreskin. I'm being fucked by a baby, he thought stupidly, and that made his balls pull up hard against his crotch. He groaned loudly as his sphincter clenched in delight and a massive blast of daddy cum spurted along his rock hard shaft, splattering his son's baby cock. "Ah fuuuuuuck," he breathed as he almost blacked out - he realized he had been holding his breath for a long time. A fuck reflex made him pull back, making him slip out of the diaper, and as he fucked the air, the next cum volley splatted his baby son's mouth and chin. He stared at the incredibly lewd sight - a baby boy reflexively licking his lips - eating his dad's warm, fresh cum! As his cock pulsed and expelled the last of his cum to run down the cock shaft and drip on his piss wet shorts, he lifted the dripping boy up and licked his mouth and chin clean, for a moment feeling the warm little boy tongue against his. My God, that was the best cum of my life, he thought as he panted, his heart beating like a dance track. On the TV the game was over, and he had no idea who won. With shock he realized that he could hear no noise from upstairs - he quickly looked at the stairs, but saw nothing. He looked at himself, at the cum drooling from his red, pissy cock, his wet, cummy pants and the dripping baby boy who still had a few white blotches on his face, felt intense guilt and fear of discovery and knew he had to clean up fast... Coming back to the moment and the bathroom, Ben blinked from the recollection and noticed he was so horned up from the memory of the diaper fuck - because that was really what it was, he couldn't pretend anymore that it was just an accident. Maybe the boys had seen him from the stairs. Maybe they had been using their baby brother as a... pee toy? He suddenly discovered that he was gently massaging the wet pee-pee of his glistening, pissy baby son. He was on the verge of cumming without having touched his own cock, but also feeling his very full bladder. Then he saw his son's blue eyes lock onto that strange, red, glistening hard thing right next to him, at a perfect height because of him lying on the wet changing table. His little fingers reached for his daddy's cock... ____ More stories like these on the Perverts 'R Us site, here on www.asstr.org Thanks to Dragon! Feedback: lestermoe at hush.com
