She wants to spend her life using handcuffs.

A New Jersey sheriff’s officer is undergoing a legal spanking after her bosses found out she once worked as a dominatrix and tried to boot her out of the department.

Kristen Hyman, who was recently sworn in as a member of the Hudson County Sheriff’s Office, is facing a disciplinary hearing where she will have to fight for her career against claims that her status as an ex-whip mistress disgraces the organization, the Jersey Journal reported.

The trouble started last month, just six days before Hyman was to graduate from the police academy, when her bosses became aware that she held the kinky job between 2010 and 2012 — and had even made some steamy, R-rated bondage videos.

Hyman is described in the online videos as “a true sexual sadist who hurts people not because she has to, but because it truly brings her pleasure,” according to filings by the sheriff’s lawyers, the Journal said.

In the videos, she’s seen wielding items “such as whips, and kicking the groin area to inflict pain upon the recipient. In most cases the recipient is naked and/or bound,” according to court documents in the case.

Hyman was suspended without pay May 26 because the sheriff’s office said her past, which she failed to disclose, is an embarrassment to the force.

But a judge later reinstated her and let her graduate from the academy. She is now facing a June 27 hearing when her job will be on the line.

Hyman has called the videos “stupid stuff I did when I was a kid.” She also says everything was staged and consensual.

The young officer said she was never naked and didn’t engage in any sex acts during her dominatrix gigs, the Journal reported.

James Lisa, one of Hyman’s lawyers, acknowledged the videos his client made might be cringe-worthy, but says they shouldn’t cost her her career.

“The videos are clearly inflammatory, but there is nothing illegal,” he told the Journal.

He also said she injured her leg during her time at the academy and had to undergo surgery.

Prosecutors in Hudson County have declined to press any charges against Hyman. She has completed all required training and has no disciplinary marks other than the current case, her lawyers said.
