A bit of text game that worked for me on my birthday with a girl who i hadn't seen in 4-6 months (previously k-closed):
HER: happy birthday loser, have a good one xx
ME: cheers babe, when do i get my present??
HER: depends what you want?
ME: last I heard they were meant to be a surprise...?
HER: you also have to earn them
ME: geez, pretty demanding there (nickname)
HER: the present is definitely worth it...
ME: I'll be the judge of that
HER: reckon you'd be a good judge though?
ME: Joking? The best judge.
HER: maybe if you ever followed through
ME: maybe if you ever made me want to

HER: you know you do
ME: hah, good coming from you (nickname)
HER: I have no idea what you mean? haha
ME: it means you want me

HER: you wish i wanted you (name)
Me: haha you're dreaming
Two days later:
HER: i'm home alone....present time?
- F-Close - and she bought me dinner first

Based the convo on showing that I was the prize, not her. Also escalating through implying sex
Obviously had some history with her, so really more for HBs you have tried previously and probably needs the HB to already have some interest in you. Really requires HB to make contact, so not that useful for any new HBs but still worked a treat for me.
