A mother and son in New Mexico say they are willing to risk jail time to maintain their romantic relationship, according to an interview with the Daily Mail.

Monica Mares, 36, and her 19-year-old son Caleb Peterson have declared they are “madly in love,” even in the face of an 18-month prison sentence, and are fighting for their right to have a sexual relationship.

Mares gave birth to Peterson at 16 and gave him up for adoption, the Mail reports. She saw him last Christmas for the first time since he was a baby, and they began developing romantic feelings for one another.

“The first time we were physical ended up holding hands and then we ended up kissing and the kissing led to other things,” said Mares, a mother of 9. “I felt comfortable with him and we fell even more deeply in love.”
