On a tip, the Plainfield police raided the house in February 2002, expecting to find illegal aliens working an underground brothel. What the police found were four girls between the ages of 14 and 17. They were all Mexican nationals without documentation. But they weren't prostitutes; they were sex slaves.
If anything, the women I talked to said that the sex in the U.S. is even rougher than what the girls face on Calle Santo Tomas. Rosario, a woman I met in Mexico City, who had been trafficked to New York and held captive for a number of years, said: ''In America we had 'special jobs.' Oral sex, anal sex, often with many men. Sex is now more adventurous, harder.'' She said that she believed younger foreign girls were in demand in the U.S. because of an increased appetite for more aggressive, dangerous sex. Traffickers need younger and younger girls, she suggested, simply because they are more pliable. In Eastern Europe, too, the typical age of sex-trafficking victims is plummeting; according to Matei of Reaching Out, while most girls used to be in their late teens and 20's, 13-year-olds are now far from unusual.
