A Massachusetts mother, who allegedly confessed to having sex with her teenage daughter’s 15-year-old male friend, has pleaded not guilty to murder.

According to the Boston Herald, Heather Salines, pleaded not guilty to six counts of aggravated rape, enticement of a minor and dissemination of pornography to a minor.

The relationship that Salines admitted to, was found out after the boy showed one of his friends a nude selfie that the 38-year-old woman allegedly sent him.

Salines told investigators that she and the boy, who was friends with her daughter, became close and developed feelings for one another.

"When I looked at him, he did not act like a 15-year-old," she told police. "He acted like a grown man. I lost myself.”

The married mother of two said that she had sex with him on two different occasions.

The Salem News reported that Salines was released on $7,500 bail Thursday.

If she is convicted, each of the aggravated rape counts comes with at least a 10-year jail term.
