(Newser) – The final prosecution witness in the Jerry Sandusky rape trial gave the most harrowing testimony yet. The young man, now 18, said a three-year relationship with Sandusky began when he was 12 years old, and it wasn't long before the sexual assaults began, reports the Daily Beast. He testified that he stayed overnight at Sandusky's home some 100 times, and the former Penn state coach often forced him to perform oral sex and raped him several times. The teen, known as Victim 9, says he met Sandusky through the Second Mile charity Sandusky founded, and his mother encouraged the relationship so he could have a male figure in his life.

"He got real aggressive and he forced me into it. There was no fighting against it," he said, describing the rapes by the man who grossly outweighed him. "Sometimes I’d scream, tell him to get off me." He said he hoped Sandusky's wife would hear his screams from upstairs, but there was no answer. "I think the basement is soundproof," he said. The accuser, who testified that he sometimes bled after the attacks, said the assaults continued until he "grew a pair of balls" and refused to return to the Sandusky household. Asked to identify his attacker, he pointed at Sandusky without looking at him. "I don't want to look at him," he said. (Read more Jerry Sandusky stories.)
