An escort that retired a few years ago, told me that she was normally at her most aroused when meeting new clients. She would normally leave her door unlatched for visitors. Waiting for the door to open and the first few seconds were magic and her desire normally went downhill from there. Occasionally a guy would show up that matched all her requirements plus freshly showered and well dressed. Lucky guy might be devoured before he had a chance to put his hand in his pocket or take a shower.
I nearly had such an experience with her. The entire first appointment took place in the shower but she looked for her donation upfront
