The feeling set in quickly. It was a familiar one - a rumbling in the tummy, pressure building in the lower abdomen. Mav had been back in diapers long enough that he'd learned to ignore this feeling most of the time, but he wouldn't be able to ignore it this time. He could tell this next load would be one for the ages.
Perfect, he thought to himself as the pressure grew.
It had been a bit of a tumultuous morning for Mav. Daddy had decided that it was time to add some new foods to the boy's diet. Instead of the usual scrambled eggs, waffles, or pancakes, Daddy had made Mav choke down an entire bowl of oatmeal. To make matters worse, the Daddy had refused to put anything on it that would have made it taste better. No syrup, yogurt, or chocolate chips. Just oatmeal with raisins and a very light pinch of brown sugar. Not a toddler's favorite way to start the day.
"Healthy foods means happy babies," Daddy had said as forced spoonfuls of the gloppy mess into Mav's reluctant mouth.
The boy had initially tried to refuse the food, but he'd relented after a firm spanking. Now, however, it was Mav who had the upper hand. Daddy would soon regret feeding him such a high-fiber meal.
Mav normally needed to sit up or stand to make boom boom, but that wasn't necessary this time. The urge to go was so strong that was able complete the entire task while continuing to lie on his belly and play with his stuffed animals. All it took was a slight lift of his right leg, and less than a second later his diaper was already beginning to expand. It turned out that Mav had been right about the load's size. It was a full ten seconds before the last of it was out, and it filled the seat of his diaper so thoroughly that it almost felt as if someone had inflated a small balloon down there.
Daddy must have heard Mav grunting. The boy noticed out of the corner of his eye that the man had turned his attention away from the clothes he was folding and was now looking at him. Mav turned his head, lifted his leg a little further to make the mess visible, and, looking Daddy squarely in the eye, smiled mischievously beneath his pacifier. They say payback is sweet. This time, it would also be stinky.
