Ronald Ayers, who was fired from his tenured position, also would type e-mails to a colleague at another college detailing his sexual fantasies about young women in his classes, or the teenage girls who worked at thrift stores he frequented, the San Antonio Express-News reported Sunday.

When the university fired Ayers for allegedly accessing pornography on university computers, they handed over his computer logs to a faculty tribunal, said university spokesman David Gabler.

In one exchange, Ayers said a girl in his class came from a broken home and wondered if she waited tables at a nude or topless bar.

"Let me find out her weaknesses, flatter her and then dig out more info to use to my advantage later," Ayers wrote in a 2005 email.

Ayers is on administrative leave with pay pending his appeal to the state Board of Regents.

His attorney, Javier Maldonado, said Ayers had not broken the law.

"We all know we write stuff in e-mails that we shouldn't," Maldonado said. "I don't think they have evidence that he did anything wrong with students."
