Цнотливість раба обличчям вниз, дупою вгору, анальний тренінг

Rod is locked back in chastity for 50 days so today I started his anal training. He is restrained face down ass up, his ankles and wrists shackled and I go to work with some dildos on his ass to get him used to taking it in the ass. At the end I write on his ass cheek with a semi permanent tattoo pen as a reminder when he looks in the mirror.
