Sincere compliments + generous tips will generally work well. When she comes in to collect the house money, while you're still dressed, tell her she is very attractive, has beautiful hair, eyes and lips, and gently turn her around once very softly while you're sitting on the table and comment what a lovely body she has and what magnificent legs she has. Be sure to let go of her before the final compliments begin.
When she comes back in and you're now undressed be sitting on the edge of the table with your legs slightly parted (unless you're the owner of a beer belly...then lie face down with no towel)so she can see that she has already excited you. I like to place the tip at one end of the table and have it be in large bills; e.g., two $50 bills or one $100 bill. She won't have to count a batch of smaller bills and there's just something about the larger denominations that makes her think maybe you're loaded.
By the way, when she invites you to lie down on the table reach down to your groin area and pull the cock and balls so they're between your legs not crumpled up under your lower stomach area. That'll allow you to get harder faster as she massages the butt and inner thighs and may even induce her to touch and blow on the package she is now concentrating on so intently.
