1. Battle of the Lips and Tongue
When you are kissing a woman, since your lips may still be relatively dry, it would naturally occur to you to use your tongue to moisten them. You're absolutely right! If you think of it, just go for it! You can let your tongue glide back and forth over her upper and lower lips, then gently flick her lips with the tip of your tongue. At appropriate times, you can use your own lips to gently suck on either her upper or lower lip while stimulating and teasing her with your tongue. If she enjoys it, she might reciprocate in the same way. You can also lightly bite her lips with your teeth, but you must control the force carefully so as not to cause her any pain!
