I'll assume you've built rapport, comfort and attraction and you just need that last little push.
I'd just try to come in under the radar, I'll quote a good technique from Mystery its actually quite low risk and you can handle any rejection relatively calm.
When she's in the middle of talking - interrupt her (not rudely) and say "shhh... you talk too much... do you want to kiss me?"
You'll have 4 main outcomes:-
Yes or any
positive IOI's -
GO FOR IT!
I dunno/Maybe... Respond
"Well... lets find out - Come here" (Swallow that pride and take lead)
No Respond
"Hey! I didn't say you could... you just seem to have something else on your mind" (Then progress with the rest of the interaction)
Not here - Respond
"I Understand..." *with a playful smile or wink* and isolate (Move away from her her group/friends or whoever)
I know it seems nerve wrecking but you can never be 100% sure, but hope this will help
(I'll keep an eye out for a video on it if I can)
