I get offers of free service for the entire day with industry girls that charge $300 per hour to guys and $1000 for a dinner date consisting of 4 hours with 2 hours of the 4 back in the bedroom.
Think big and you can get these offers too.
I usually refuse though because it ruins the mood when girls offer sex for free.
Many, many times I have turned girls down who offered $1000s in free service to me because I only wanted to see Asian Angela. I have actually paid Angela money after having refuse free service from others girls just hours earlier. That's how much I like Angela. She is beyond my #1 ATF sex worker.
Think in terms of abundance and any girl you meet will offer you free service, except Asian Angela. Asian Angela probably does give great service and extras to guys - but not for me because I idolize her too much. The better you treat a woman, the worse she will treat you.
If you think you cant get free service or full service for that matter, then the girl will never offer you full service.
Every massage girl does full service with some of her clients.
