(CBS/AP) BELLEFONTE, Pa. - The second day of testimony in the sex abuse trial of former Penn State assistant football coach Jerry Sandusky got underway Tuesday morning with tearful testimony from the young man prosecutors have labeled "Victim 1" - a teenager whose mother's complaints in 2008 prompted a grand jury investigation.
The young man, now 18, tearfully told jurors the former Penn State assistant football coach performed oral sex on him after meeting him through his charity, The Second Mile. He choked back tears as he spoke of an encounter that included Sandusky fondling him, kissing him and ultimately engaging in a sex act.
"After kissing my forehead and cheek, he moved to my lips," the man said. "He kissed my lips, then he moved to my back again... Then he started to rub underneath my shorts."
The teen told the jury Sandusky would also initiate contact by blowing on his stomach and performed oral sex on him.
"I spaced," the alleged victim said. "I didn't know what to do with all the thoughts running through my head, I just kind of blacked out and didn't want it to happen. I froze."
The teen, who testified that he met Sandusky through "The Second Mile," which is the former coach's charity for at-risk youth. He said he had grown up in public housing and did not know his own father.
"I kind of thought he sees me as family and this is just what his family does," he testified.
"I didn't know what to say," testified the man. "I was embarrassed and confused and didn't know what to do. My mom felt I was doing stuff she couldn't do with me, she enjoyed the fact that I had a role model. I couldn't just say no."
He testified that after he broke off contact with Sandusky, the former coach came to his home and yelled at him for not spending more time with him. He told the court that the argument got heated and that eventually hid behind a bush to avoid Sandusky.
"I got extremely, extremely scared," testified the man. "With all the connections he had if he really thought I would say what happened that he could hurt me or someone close to me."
The teen is the second of Sandusky's accusers to testify in the former coach's high-profile child sex-abuse trial. Sandusky has denied all allegations of sexual abuse against him. His attorney, Joe Amendola, told the court in his opening statement Monday that the alleged victims have financial motives for making their allegations.
According to the grand jury report on the case, Victim 1 alleged that he met Sandusky through The Second Mile in 2005 or 2006 when he was 11 or 12 years old. The young man told the grand jury that he began staying overnight in a furnished basement bedroom at the Sandusky house in 2007 and that Sandusky would come into the room at bedtime and "crack his back." It was a practice that allegedly led to Sandusky performing oral sex on the boy more than 20 times in 2007 and 2008.
Meanwhile, according to PennLive.com, assistant football coach Mike McQueary and alleged Victim 5 have been told to be prepared to testify Wednesday, but they will likely not testify until Thursday.
