Ok guys, im offering full credit to gambler for this, but i want to bring more awareness for this.

Tongue in cheek method.
Saying something, but then quickly discrediting it - for eg
"can you imagine you and me baby, under the stars, where going places"
while saying this, have a small smile go across your face and laugh jokingly at the end.
It will let the girl experience the emotions that are being said through this, but will also make her feel comfortable and it shows
1. humour
2. Non AFCness

It will also keep her guessing
"hmm, does he actually think we can do this stuff"
or
"he keeps saying this, does he mean it or is he just messing with me"
This allows you to physically advance with sexual tension without it seeming un-awkward.
- another point Gambler makes is to never escalate sexual tension with words; such as " lets kiss" ( for a easy example)
Its easier to escalate sexual tension with actions, I.e going kino, touching her body while saying it, using eye contact to increase the tension.

This effect is a good thing to use mid-game after making a connection with the target, as it shows that there may be a potential future relationship, including playfulness.

thanks,
Twelvegone

Additional note
i tried this type of strategy on a girl today
We almost kiss closed, however her brother got on the bus
