Sending an email/ call a day later saying you had a nice time is a good idea, but, I dont think there is any magic lines - but I'd think the following:
1) see if you can kiss her on her lips or take her to a private area to see if you can kiss her on her lips. The chapstick or lipstick line: "Hey, is that lipstick or chapstick? <lipstick/chapstick> Good, I need to borrow some, <kiss her>. <she is wearing nothing>, then say 'Good, I wouldn't want anything going on my lips -- then kiss her if she's receptive.
<Not field tested, but brainstorming - I may do it myself on my next date and write about it>
2) if she's not ready for a lip kiss (brief kiss on her lips) and turns a cheek, then you tried, just see if you can handshake her - EUROPEAN HAND SHAKE, take her hand and kiss it on the top and say "Madmoiselle, it has been a pleausre meeting you" in a French accent or something.
The EUROPEAN hand-shake may be a more SAFE option as it's classy, humorous, and has the right effect. I may do this on my next date since it has the effect of charm. I'm debating within myself whether a lip-kiss or a European hand-shake is better.
Listen to what others are saying about last things to say, but make sure you get some kino-touch before you are leaving and wink - let the date make the last lines, and tell you she wants to meet you again, usually they do that if you are conducting a good-date. If they are not into you, and you are not conducting a good date, then it may come across as desperate if she isn't acting like she enjoyed the date, your company, or is into you.
