ChinaJoy is an expo and conference held every year in Shanghai, China that is usually about video and computer games. It is also famous for the many hot girls working for different companies at the show as models. Many guys like to go each year just to look at the pretty girls and take pictures of them.
At last year’s ChinaJoy, the popular trend was “camel toe” because a lot of guys noticed and took pictures of girls with very tight pants. This year, it looks like the popular thing is knees with suspicious markings.
Some KDS Forum replies:
They all like the same position
The mark of giving a blowjob on your knees
Hey, they have work at night too
Looks like blowjobs are popular this year…
What do you think of when you see marks on girls’ knees?
