Seeing this thread continue made me curious (who is Tussinee?), so I read the first few posts and checked the vids (I cannot access her site from Thailand). Perhaps it's because the internet is slow here, but because of the buffering, I had several longish looks at her face before getting bored and moving to another site.
Before I saw the exchange of posts on her age, I had concluded she was at least 25 and maybe even 30. She may be small, but she has the skin of a Thai woman in her late 20s. If she really is 18, she has serious skin problems.
