By Rafael Romo, CNN - They were only 14 years old, cousins from a small town in central Mexico, when a fun trip to the local fair turned into a nightmare of drugs and forced prostitution.
As Maria and Lupe - CNN has changed their names to protect their identities - were waiting by the highway for their early evening bus home, they say a semi-tractor trailer stopped right in front of them and two men got out.
There were no conversations. It all happened very quickly, the cousins say. "They were two men who were wearing black masks like hoodies. We couldn't see their faces," Maria said.
Lupe says she didn't even have time to react. "I only felt that they put something on my nose and that's all I remember. The last thing I remember is yelling for help," Lupe said.
