I saw a lot of reviews of their girls but i can't find the agency's website. How do they advertise if they don't have a website?

They have a website, though it definitely is hard to find it. Are you interested in booking one of their girls? Nana is pretty popular at the moment.

Thanks man. They have only two girls at the moment. Seems like they don't update the website too frequently? 

As their name says VIPOTG - VIP Oriental travelling girls, so their selection changes all the time, sometimes they have plenty of girls and sometimes they have one or two, you never know.

I saw Nana recently and i highly recommend her. She's submissive and her PSE is perfect. You can do whatever you want with her.
