Elise is being punished for purposely urinating in her diaper and then masturbating. Bob, who is sick of changing her diaper, decides to teach her a lesson she won't soon forget. Instead of changing her right away bob drops the heavy bambino to the floor and unloads a torrent of his own urine into it before placing the filthy diaper back onto her. He then places her into bondage, spanks her and then leaves her for an hour.
