Whispering dirty thoughts to her: “I was looking at you when you were there, you look so sexy” or “I can’t wait to take you home” or “things I’ll do to you when we’re alone.”
Take her to a small and discreet place and start kissing you passionately. Kiss her on the neck, lick her ear, gently pull her hair if you can. Then stop and continue your normal activity.
