Long Island, NY- A Long Island man didn’t just create a sadomasochistic Web site – he lived the twisted life to a fault, prosecutors allege.

Jury selection begins tomorrow in the trial of sex perv Glenn Marcus, who ran slavespace.com on the Web. Federal prosecutors accuse Marcus, 53, of sex trafficking, distributing obscene materials on his Web site and forced labor – allegedly ordering one woman to repeatedly click the links on his Web site “for hours on end” so he could earn fees from other Internet sites.

“If [the victim] took a break from working on the Web site, the defendant beat and tortured [her] as punishment,” according to court papers filed by the government.

The stomach-churning charges allege that Marcus placed the woman naked in a large plastic bag and choked her, that he mutilated her genitals, locked another woman in a dog cage and posted images of them on his Web site, which was shut down after his arrest in May 2005.

He also allegedly threatened to send the images of the two women to their parents and newspapers in order to humiliate them, prosecutors contend.

The women are expected to testify under their first names only to protect them from embarrassing publicity.

Marcus was living at his parents’ home in Woodmere, L.I.

The defense will argue that Marcus’ relations with the women was consensual. “If the jury is willing to look beyond the bondage, dominance, sadomasochism context of this case, and examine the evidence, it will be very clear that my client is innocent,” said his lawyer, Maurice Sercarz.

Marcus faces up to life in prison if convicted.
