Almost 99% of the Chinese student pictures on VS are fake. Although at the doorstep, quite a few, I should say 10-20% do look fuckable.
The big difference between EE B&S and these is that once you like a gal and pay her, the service isn't too bad. They at least try to make you comfortable and put in some effort. Compared to Rum EE who most likely will shit over you, once you have handed over your hard earned cash to them
The 'Chinese students' I saw didn't seem trafficked. Though they did seem to come from rural areas, few spoke any English, were mostly in their 30s or 40s, with c section or stretch marks and the trademark huge bushes!
My opinion was, trafficked unlikely but more like working with a heavy heart,doing a job they don't really fancy. In order to beat poverty and give their family a better life. Sounds like a lot of us though
