In part one of this custom clip. Sinstress humiliates her slave by making him a diaper loser. She changes her gloves as she undresses his smelly diaper. She puts new gloves on and wipes up his gross ass. It's such a nasty mess, she is very upset. She wipes up, puts baby cream on and cleans his messy asshole. The entire time, she humiliates him for being a diaper bitch who needs nutted. She puts a clean diaper on him and discovers he has an erection. It's likely from shoving the dirty diaper in his face.
