I saw Vivian at Angel Spa last weekend. Age is probably early 40's, maybe even late 30's if I'm being generous. Asian looks definitely can be deceiving when it comes to age since they normally look younger than they are.
One good thing was she was never in a rush even for a 30 min appointment. She allowed touching and showing top but nothing else. It was also my first time so you may get more if you're a regular. I don't consider her having a bubble butt also but she is petite. Said she only started to work in March again. Not really my type so I won't repeat.
