I have two similar WL's. One who i saw for years and dropped alot of cash on, before lockdown finally got upgraded to BBBJ. Couldnt get FS no matter how hard i tried, Got her mobile number and home address for privates but no FS. The other will let me do anyting but penetration, no amount of money would let me upgrade to FS.

On the otherside i've managed to get FS and BBBJ from some popular WL's here (Thai) that other punters reviewed they could never get. So its different for everyone.
