First
, walk behind her and start kissing her neck, then move to the front and kiss her lips, while (if shes wearing a caca with a button) unbuttoning the first few buttons if not if she is wearing a shirt where her collar bone is exposed,.Proceed to kiss her collar bone. Go back and french her. Run your fingers through her hair while kissing her, get her really turned on! If you really care about her, tell her how much you love her (if not don't say love or lead her on). Tell her how beautiful she is complement her, make her feel special. Lay her down on the bed kiss her all over, use just the right amount of toung to give her goose bumps rub your hands between her inner thighs (make sure you wash your hands and make she shes ok with it. Start rubbing her clit first up and down motions and switch to circular patterns (dont stay in one spot for to long our else it gets numb or may hurt) let pull her panties down and give her oral satisfaction for about 10min. The key to blowing a girl away (well for me anyway) is how much foreplay there is in the beginning!
Hopefully I helped you out a tad bit!
