you could probably do it in a playful way... depends how good your game is though...
the one i usually use (night game) is:
Me: "Ok well i have to get going now

... oh but before i do... do you know how the french say goodbye?"
Her: "Nope :S"
Me: "come here ill show you..." grab her head... kiss her on 1 cheek... then on the other cheek... and then on the lips (no tongue... its just a peck)...
but yeh... i dont know if you could use that in day game... i dont game during the day so i have no idea what works and what doesnt

but use it to make your own...
