If it's straight up, you're doing great, otherwise, here's what to do: Pull his balls out. If the pants are too tight, pull them down. Now hold his balls in your left hand and his cock in your right. Squeeze it gently down toward the bottom of the shaft and get ready to suck. Run your tongue over your lips to get them good and wet and look into your man's face. He wants to watch you suck him off. Men love to watch. Now open your mouth just slightly to tease and excite your man and come very close to his cock. Breathe on him, blow on him with your hot breath. Stick your tongue out again and reach for him, tease him.

Making sure your tongue is dripping wet, begin at the bottom of his shaft and lick upwards, slowly. Turn your head sideways and pretend to take a bite of him, very gently setting your teeth into his flesh. Wet him again with your tongue and use your hand to spread the liquid around if necessary. A wet cock looks and sounds a lot sexier than a dry one. Your left had meanwhile is massaging those balls, perhaps scratching them lightly with your fingernails. You may also want to reach behind and underneath the balls to get to that ever-so-sensitive area just before the anus, or even to run your fingers over his anus very lightly. Since the muscles that cause erection originate back there, this will produce a reaction in his cock.
