A Silicon Valley tech titan has been sued for $40 million by a woman who claims he used her as a sex slave for 13 years.

Michael Goguen, who had worked for a firm that funded Google and Paypal, had been “sexually and physically” abusing Amber Laurel Baptiste over more than 13 years after meeting her at a strip club in Texas, her lawsuit alleges.

Baptiste claims she was brought to the United States from Canada by human traffickers when she was 15 years old and Goguen had promised to save her from human trafficking. But, soon enough the woman realized that the American titan would become an even worse predator, New York Post reports.

The former stripper said Goguen made her endure demeaning sexual acts, sodomized her for “six hours at a time,” and forced her to call him “king” and “emperor.”

Goguen, who was forced to resign from his position at Sequoia Capital, did not deny their sexual relationship but he insisted the sex was consensual.

Baptiste is now demanding $40 million and claims that the two agreed on the amount to compensate her for the horrors she had suffered, but Goguen, who has already paid her $10 million, said she is “a woman scorned” and a victim “of her own delusions.”
