I think you need to go for a full bum grab now. It's no good whispering sweet nothings in her ear if you just want to get your end away, you need to get in at underwear and bare skin and mucus level early on.
make sure you get a florist bunch where they have their own vase or cellophane water store so she does't have to faf with them before you go out etc ... Small kiss unless she makes the first move for something else. Have a lovely time.
