McQueary's two hours on the stand followed grueling, often sobbing, testimony from the 18-year-old recent high-school graduate credited with launching the investigation into Sandusky.
In his testimony, a teenager known until now as Victim 1 testified that Sandusky turned a routine of back-cracking, kisses on the forehead and "stomach blowing" into several instances of oral sex in the basement of the former Penn State assistant football coach's house.
The teenager, who wore a wrinkled white dress shirt untucked from a pair of khaki pants, spoke timidly over many deep breaths as he detailed how more than 100 sleepovers at Sandusky's house were followed by the ex-coach stalking him at school.
When he first tried to report his experiences, the witness said, school officials were skeptical.
"They said he had a heart of gold, he wouldn't do anything like that," he said. "They didn't believe me."
The Legal is not publishing the names of Sandusky's accusers.
Sandusky watched stoically and didn't appear to react during an hourlong direct examination by McGettigan.
It was as McGettigan asked the teenager about the first time Sandusky performed oral sex on him that the witness broke into tears.
After describing a ritual of Sandusky cracking his back and blowing on his stomach, the teenager stopped, paused for nearly 20 seconds, and took a brief, but direct, glance at the defendant.
"He put his mouth on my privates," the witness said, turning his head down and crying.
