Jeff wondered how much control over his bowel movements. He already knew he couldn't prevent himself from pooping if he had to, but could he poop on purpose? As he begun to push, he automatically squatted slightly, again causing the wet diaper to move back and forth a little. He pushed as hard as he could, but except a tiny bit of gas - not even an audible fart - nothing came out. Jeff decided to try in another position, lowering himself to his hands and knees. Again he pushed long and hard. It felt almost painful in his butt and he felt the pressure in his whole body, his head becoming warm and probably red. Finally, he produced a tiny piece of poop, barely noticeable in the diaper. Jeff decided to end his experiment - apparently, at this age he'd just poop when he had to and not at any other time.
He noticed that despite its content, his diaper didn't let out any smell - or at least none he could notice. He rubbed over his crotch with his hand, feeling the warm diaper through the pajama fabric, and smelled on his fingers - they weren't smelly either. Still, he undeniably felt the warmth and weight between his legs, and around his wee-wee his skin felt damp. He suspected the diaper was filled almost to capacity, and he wondered what it would take to make it leak. He didn't really want to get his bed or even Mr. T wet, but found that the stupid pajama deserved some pee stains that would send it away to the washing machine. But how could he get the diaper to overflow?
