The monster strapon

Mistress Anette first prepares the slave's anus for the rough penetration. She uses some lube and she pushes her fingers inside him to make him relaxed and wide. The slave can hardly relax with a huge strapon in his near future, but he must, because either way it is going to enter his body. When Anette feels him ready, she slowly inserts the tip in his ass and she pushes to make the roughly thick strapon disappear.
