Sandusky Victim 1 Sketches

Prosecutors are expected to call more witnesses Wednesday to testify against Jerry Sandusky, the day after jurors heard from a man whose accusations upended the Penn Statefootball program.

The man, identified as "Victim No.1," said he stayed at Sandusky's house more than 100 times as a boy, and the former assistant football coach repeatedly sexually abused him.

Now 18, the man said he grew up without a father, living with his mom and siblings, and met Sandusky at Second Mile, a foundation the former coach created for needy children.

"At first he would kiss me on the forehead goodnight," Victim No.1 testified on Tuesday. "Then it was kissing me on the cheek, then rubbing my back and cracking my back."

Sandusky's roaming hands would later move to "rub underneath my shorts," he said. The alleged abuse further escalated when Sandusky "put his mouth on my privates."

"I spaced," the alleged victim said. "I didn't know what to do."

Later, the former coach allegedly told him that "it's your turn," he added. "He made me put my mouth on his privates."

The man's emotion-filled descriptions were often accompanied by tears, kicking off the second day of testimony in the high-profile child rape case.

The grand jury report cited evidence that Sandusky, who has pleaded not guilty, "indecently fondled Victim 1 on a number of occasions, performed oral sex on Victim 1 on a number of occasions and had Victim 1 perform oral sex on him on at least one occasion."

The teenager, who transferred schools amid the fallout from the investigation, graduated from his new high school this past weekend, according to his attorney Michael Boni.

He is one of 10 boys who, prosecutors say, were sexually abused by the Nittany Lions' longtime defensive coordinator over a span of 15 years. Sandusky's trial on 52 charges is expected to continue for about three weeks.

The alleged victim's elementary school wrestling coach also testified Tuesday, saying that he'd seen interactions between Sandusky and the boy and "thought it was a great thing because (the boy) needed a father figure."

But Joe Miller recalled one day when returned to the weight room and found Sandusky and the alleged victim "laying together side to side" with his arm on the boy.

"At the point Jerry propped up and said 'Hey there, we're working on wrestling moves,' " he testified. "They were both startled that I came in."

On Monday, the first person to take the stand after opening statements was a now 28-year-old man identified as Victim No. 4. He said that Sandusky routinely had the then-teenage boy perform oral sex on him while the two showered together on the school's campus and elsewhere

"It would have to be 40 times, at least," he said, adding that the abuse started when he was 14-years-old.

The man on the stand Monday, as well as Victim No.1, met Sandusky through Second Mile, the nonprofit group the ex-coach founded.

He described growing up without parental oversight before Sandusky took to him -- playings sports with him, paying for uniforms, a snowboard and other items, taking him to Penn State games and doing other special things. Victim No. 4 said Sandusky also drove him to buy marijuana once when he was 15 or 16 and had bought him cartons of cigarettes.

Despite what he described as systemic sexual abuse, the witness said he was "scared" and reluctant to talk about it and "lose the good things I had." But he said he decided to tell his story after hearing that "this happened over and over and over again."

While Sandusky said he wanted him to succeed and was nice to him in public, Victim No. 4 said their relationship was different in private.
