A girl will never forget your kiss if you gently caress her lower lip with your lips... then you softly touch her tongue with your tongue, then you slowly breathe in as you stomp on her foot as hard as you can! That's a kiss she'll never forget! HA HA HA!
Then, after the emergency room doctors untwist your testicles, come back here and I'll tell you how to kiss her the right way. :)
