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.
