Have fun with it. Be enthusiastic. Ask what he likes. Take your time. Tease him. Kiss all around it then slowly lick up and down a few times. Play with his balls gently. Look up at him and smile to let him know you love it. When you start sucking it go slow then faster and see what he reacts to. Take it deep then focus on the head. Mix it up. Use your hand and mouth together. Moan. Get sloppy. Swallow and keep sucking.
