When my first Master trained me to deepthroat his 10 inch cock i had to suck him for 2 hours straight! He slowly made me get used to his size and girth, the first time he allowed me to take him in fully we where already over an hour in the session. Then a full hour only deepthroating and facefucking. We did that more often but taking less and less time for it. After a half year i had complete control over ny throat
to Devboy96 :A good dom will be patient if he sees that you are making full effort to progress. This is a great feeling that knowing your sub is getting better and better with each session.
