SUNNYVALE, Calif. – A Silicon Valley lawyer allegedly paid a 16-year-old girl hundreds of dollars for sex and propositioned her 17-year-old friend with graphic e-mails, according to court records.

Jason D. Borrevik, 32, of Sunnyvale, had sex at least three times with the 16-year-old San Francisco Bay area girl he met on the Internet, according to an affidavit filed Tuesday in Santa Clara County Superior Court. The girl told police he paid her between $140 and $200 for each encounter.

Borrevik, an attorney at Wilson Sonsini Goodrich & Rosati, one of Silicon Valley’s most prestigious law firms, was arrested last month on charges of having sex with a minor. He’s married and has an infant son.

Borrevik is on administrative leave from his job at Wilson Sonsini Goodrich & Rosati, which represents high-profile clients such as Hewlett-Packard and Apple Computer.

Borrevik allegedly e-mailed the 17-year-old girl graphic photographs to entice her, but instead of meeting with him, she reported the incident to Milpitas police in August.

In a sting operation, a Palo Alto police detective pretended to be the older girl during an online chat with Borrevik, who allegedly admitted to having sex with the 16-year-old.

A clerk at the Palo Alto Townhouse, where Borrevik allegedly met with the 16-year-old at least once, said Borrevik had rented a room there more than 40 times in the past four years and had arrived with an “underage-looking” girl in the weeks before his arrest, according to the police affidavit.
