Andrew felt rather than heard a slight popping from his behind and crouched stock-still on the carpet as the weird feeling became stronger.
There was a feeling of something coming out of his behind and then his abdominal muscles contracted fully to expel the contents of his rectum completely into his diaper. Andrew was stunned by the sensation. The hypersensitive nerve endings of his infant’s body interpreted the sensations as incredibly pleasurable. Despite his adult revulsion to defecating in his pants, the feeling was simply too good to try to stop. Waves of pleasure rolled up his spine as he dumped a prodigious load into the back his diaper.
