The physical development that enable you to apply mouth pussy to a dick in a consistent and robust way. Especially where thick fat dicks are concerned. It's real work to stay on the dick without need for breaks. The second: Ability to read the dick. What's working, what's not working, what is needed. Part of the joy of sucking a dick is that as cocksuckers, there are physical, intellectual and artistic challenges that are intertwined and must be engaged to reach our goal: delivering pleasure, so much so that we get rewarded with cum in our mouth. A great cocksucker isn't just sucking, they are thinking, reacting, planning, and feeling.
