A Nebraska woman has been spared jail for marrying her dad following a twisted competition with her half-sister over who could have sex with him, according to reports.

Samantha Kershner, 21, met biological dad Travis Fieldgrove, 40, when she was 17 after begging her mom to reveal who he was.

They started sleeping together last September sparked in part by a “jealous competition with her half-sister regarding who could have sex with their father,” according to court documents obtained by the Omaha World-Herald.

When police started asking questions, the pair married on Oct. 1 at the Adams County Courthouse in Hastings, according to the affidavit.

DNA results showed a 99.999% probability that Fieldgrove was her dad, the affidavit said.

Kershner was initially charged with incest but pleaded no contest to reduced charges of misdemeanor false reporting, according to KHGI TV.

She escaped jail time and was sentenced in Hall County court to nine months of probation, the report says.

Her father last month was jailed for two years, and ordered to serve a year’s post-release supervision with no contact with his daughter.

Their legal problems are not over, however. The two are also wanted in Adams County on more incest charges for getting married there, with Kershner also facing a charge of making false statements under oath, the TV station reports.
