HARRISBURG, Pa. (AP) — Jerry Sandusky's adopted son says hearing the first victim on the witness stand in the former Penn State coach's trial helped push him to come forward with his own allegations of abuse.

Matthew Sandusky said in a Thursday broadcast of "Oprah Prime" that he recognized elements of his own abuse when he sat through testimony by a young man described in court as Victim 4.

He says he wonders if it wouldn't have been easier to simply keep quiet.

Matthew Sandusky now claims oral sex was part of the abuse, which contradicts what he told police investigators in 2012.

He says Jerry Sandusky would tickle him, blow on his belly and wrestle on the floor, and the encounters gradually became more sexual.
