Just wanted to share something similar. Inspired by your OP, not as hardcore, though.

Met a girl yesterday, 24 years old, had many inside jokes, one of them being us getting married in a monsoon wedding (we're both half indian) and going on a honeymoon. Sexual tension was huge by the end of the night.

Today:

Me: Let's be spontaneous and go to Italy for our honeymoon. I've got the tickets. Your husband, Tr@veler.

Her: Ya...sounds great ^^where exactly do you wanna go? Roma? Your loving wife, HB.

Her: ...And when? By the way...when is our wedding?? Im sorry sweety but I somehow missed the date ^^

Me: Babe lets go to venice. We will have italian ice cream and great sexual adventures in their boats. Sound good?

Her: Hahahaaa...whatever you like honey

Me: Our flight is tomorrow. We need to start packing. You forgot your clothes at my place. Come pick them up!

Her: Oh ok...i will hurry up which clothes? The dessous or the normal ones? ^^ can't you pack them for me?

Me: I want to see the dessous on you one more time before the flight. Can you do that for me?

Her: I thought they are for the honeymoon...kinda surprise you know

Me: Darling you think of everything. (Ask her to come join me in the city).

Her: Always...u know me...thats y u chose me. no? (couldn't come out cuz logistics...)
