First of all, start slowly. Don't just grab your special someone and cram your tongue down their throat. Yes this can be nice later on for more passion, but to start tease a little. Kiss lightly.
Step2
Gently lick their lips with your tongue. Move slowly and breathe your hot breath onto their waiting mouth.
Step3
Suck their bottom lip into your mouth and give it a gentle tug.
Step4
Then slowly move your tongue in their mouth, but do not swallow their face! Nothing makes a kiss worse then someone swallowing half of your face. Use just enough tongue to make them want more.
Step5
Pay attention to their breathing. Feel their body language. Are they breathing faster, moving closer, almost begging for more with their actions....then you're on the right track!
Tips & Warnings
Be sure to use a good mouth wash and have good daily dental hygiene.
Flavored lip gloss is nice, go with a neutral flavor that just about everyone likes, ie- strawberry or watermelon
A little nibble with your teeth can be good on the lower lip to, just be gentle.
Also don't forget a little moaning goes a long way to encourage them.
