I got a new open mouth gag today. :)
Gave me an opportunity to think about, and practice Sir’s very specific rules for sucking..
-Depth: consistently going down far enough to please my cock as much as possible
-Tongue: proper use of tongue while sucking
-Enthusiasm: showing obvious desire / motivation to please and suck like it is your favorite candy
-Moaning: making sure to give grateful moans while sucking
