A jury has been told how a Barnsley man abused the trust of parents as he sexually abused five children over ten years.
Jamie Mann, 26, of Dennison Court pleaded not guilty to 18 different charges at Sheffield Crown Court.
The charges also included two allegations of rape against a young boy, with the youngest child aged just five at the time of the assault.
The prosecution said when Mr Mann was left alone with a child he would encourage them to engage with sexual activity with him.
Prosecutor Richard Sheldon said Mr Mann would force himself on young boys and tell them it was okay because ‘he and his friends would experiment all the time’.
The prosecution said one of the children counted in his head for 45 seconds while Mr Mann assaulted him.
Mr Mann was arrested in October and was granted bail at the time.
He is still on bail and denies all charges.
He was interviewed by police for a complaint of sexual assault against a child in 2008, but the police did not have enough evidence to prosecute.
This complaint is one of the charges laid against him in the current trial.
The case continues.
