BELLEFONTE, Pennsylvania (CNN) -- An alleged victim of Jerry Sandusky testified Wednesday that Penn State's longtime defensive coordinator threatened him as a boy after sexually abusing him in the basement of his central Pennsylvania home.
"He told me that if I told anybody, that I would never see my family again," said the man identified as "Alleged Victim No. 10."
He said Sandusky pinned him down and engaged in oral sex on at least five different occasions, and later apologized for his behavior.
"He said that he didn't mean it, and that he loved me," the man testified Wednesday.
The alleged victim, now 25, spoke on the third day of testimony in a high profile child rape case against the school's former football coach. He is one of 10 boys, prosecutors say, who were sexually abused over a span of 15 years.
Sandusky pleaded not guilty to 52 criminal counts and has denied his interactions with the children were sexual. The trial is expected to continue for about three weeks.
John McQueary, the father of a then-graduate assistant who testified that he saw Sandusky raping a boy in a university shower, also took the stand Wednesday morning.
"I knew there was something wrong," the elder McQueary said, describing a phone conversation with his son following the alleged incident.
"I said, 'What's the matter?,' " McQueary recalled. His son, Mike, then told him: "Coach Sandusky in the shower with a young boy," the elder McQueary testified.
"He was positioned behind the young man, and I believe he said up against the shower wall," he testified. "He said, 'It didn't take a rocket scientists to figure out what was going on.' "
On Tuesday, Mike McQueary testified that he saw what appeared to be Sandusky having anal sex with the boy.
He said he informed university officials, though did not use the words "anal sex" because he "didn't feel comfortable."
Defense attorney Karl Rominger cross-examined McQueary Tuesday, asking the former graduate assistant about angles of his view and the reported date of the alleged incident, which prosecutors later had to adjust from 2002 to 2001.
The elder McQueary also testified Wednesday that he met with Gary Schultz, the former Penn State vice president who oversaw campus police, to follow up on what his son had told authorities.
"I made Mr. Schultz aware that I knew of this incident, and understood that Mike had met with him, and he had told Coach (Joe) Paterno," he said. "Mr. Schultz said that he had heard noise about this before, earlier than Mike's report."
Prosecutors claim Schultz held a secret file that detailed alleged incidents pertinent to the Sandusky investigation, which was not made available to the grand jury investigation.
Schultz and Tim Curley, Penn State's former athletic director, have pleaded not guilty to charges of perjury and failing to report an alleged sexual assault of a child.
The file allegedly shows inconsistencies with what Schultz and Curley told a grand jury, according to court documents filed by prosecutors.
They say e-mails from Schultz, Curley and others further contradict their own testimony, though CNN cannot independently confirm that account.
The university responded Tuesday saying that it had received "several subpoenas and gathered documents from many sources across the institution."
"As soon as any relevant documents were discovered, the university immediately provided them to the office of the attorney general and the Freeh Group," it said, referencing an independent investigation.
In opening statements, defense lawyer Joe Amendola suggested his client would take the stand and say he routinely "got showers with kids" after working out.
The former coach has always maintained his innocence, Amendola said, claiming his client's alleged victims had changed their stories and were questioned until authorities received the answers they wanted.
"A lot of people lied," Amendola said. Some of the alleged victims have civil attorneys, he noted, calling that unusual. Others, he said, have a financial interest in the case.
"One of the keys to this case, one of the keys to your perception ... is to wait until all the evidence is in," Amendola told jurors. "Some of it will be graphic. ... It's going to be awful. But that doesn't make it true."
A man identified as "Alleged Victim No. 7" is also scheduled to testify on Wednesday.
On Tuesday, "Alleged Victim No.1" said he stayed at the former coach's house more than 100 times as a boy, and that Sandusky had 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 he created for needy children.
"At first he would kiss me on the forehead goodnight," Alleged 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
