Cock Sucking Training

Description: As you know pet has given me complete control over his mind & body to do as i please with.  pet always tells me about his fantasies about being cucked by me and watch me with alpha — pet isn’t even close to be given such a treat, he has to show be he’s able to please alpha, so i had to give his throat some training before. what would you rate his cock sucking skills? do you think you can do better?
