A young boy allegedly raped several times by a Christian Brother was reprimanded and told by senior school staff he was "going to hell", a Melbourne court has heard.
John Francis Tyrrell also on occasion beat his victim with a leather strap after the assaults, the Crown has told his trial.
Former brother Tyrrell, now 79, has denied 14 historical charges including indecent assault and buggery from his time teaching at Geelong's St Joseph's College in 1965 and 1966.
The boy was aged between 10 and 12 at the time of the alleged assaults, which according to the victim happened on 140 occasions over that two-year period.
Crown prosecutor Joanne Piggott told the County Court of Victoria on Monday that when the boy alerted senior members of staff to the alleged abuse, he was told he was "going to hell" and would be expelled.
The boy's mother had organised special classes with Tyrrell for her son, who she felt needed extra help at school, the prosecutor said.
However, the private after-school meetings turned abusive when Tyrrell assaulted the boy in a room near his classroom, in a science storage room and in the school hall, Ms Piggott claimed.
On one occasion the boy vomited after the abuse, with Tyrrell beating him with a leather strap for getting vomit on his clothes, she said.
If the boy turned up for the meetings after Tyrrell had already arrived, the child would receive a beating, sometimes with a pair of dirty socks shoved in his mouth, the prosecutor continued.
It is also alleged Tyrrell would squeeze one of the boy's testicles while he was abusing him, so hard the child "would see bright lights or pass out from the pain".
Ms Piggott said the boy was abused extensively.
"He counted 140 occasions over that two-year period," she said.
"He can recall the number of times ... because he kept thinking that one day it would have to end."
She said the boy had an "outburst" after missing school one day, and told senior staff he "wasn't going to cop Brother Tyrrell f****** him every day" but was reprimanded and told he was going to hell.
"(The alleged victim) walked out of the school and never went back," Ms Piggott said.
Defence lawyer George Georgiou said his client denied "anything of a sexual nature occurred" and that the complainant was "not being truthful".
The trial continues.
