Omaha, NE - The details of this story are hard to read, but are an important warning for parents.  It was just two weeks ago that Omaha cops finally snagged Jonathon Johnson after possible years of abuse. Tonight we hear exclusively from what may have been his youngest victim, starting at age five.

"Everybody knows that sex feels good it doesn't matter what age you are," said Jonathon Johnson in a past interview. We've heard all the disturbing reasons on why Johnson molested young boys, but now it's one boy's turn to do the talking.

"He'd always say it's ok bud just don't tell anybody," says a Johnson's step-son. His step-son claims for three years, he experienced the unimaginable. Wiping away tears he tells me Johnson would sneak downstairs in the middle of the night.

Obviously talking about this is hard on the boy, but for mom it's not any easier. "He hurt my baby, he hurt me. Do you have any idea what it's like to know that I slept with him, that I stood at the alter with him." Mariah Lovass was with Johnson for 5 years. She had no clue the nightmare he'd reportedly exposed her son to. And even now, years after she caught on to his lies, it's still extrememly tough to handle.

All Lovass says she can do is try to be strong for her son. And together they'll move forward, but it is their past this boy wants other kids to learn from. "If it happens just say it, just say it and get it over with." It's that message that drove them to do the interview and the hopes that Johnson spends life in prison. Right now he's in jail waiting for his trial. Johnson's accused of molesting 4 boys, his step-son is the only one he won't admit to.
