As I PLAY Him like a musical instrument…I can feel His arousal grow beneath my digits. To really master this instrument, you must play with feeling, emotion, and expressiveness & practice will promote & improve quality…by using the entire horn, upper & lower case can be excellent for developing a sense of pleasure and improving lengthened & hardened quality. I would recommend some kind of thoughtful approach to playing this implement…work out an agreeable exercise and use it consistently. Listen to what you are doing, hear how the tone in His moans change in key from the way you caress it. If need be make small adjustments and observe. Practice slowly at first, and work it up to a faster tempo…until His notes trickle down His tool & His groans play out like a beautiful symphony.
