Урок пелюшки сестрички: писяння цнотливості та фістинг

My sissy bitch is not allowed to pee in the bathroom, so I've been fantasizing around a diaper lesson for him. Starting with some chastity and anal stretching with one huge dildo, I will continue inserting a huge butt plug into his tiny ass and let him diapered for a while. Later it will come the pee discipline, and it makes me horny the idea about fisting his wet ass while I masturbate her until she cums for me...
