A SEX addiction therapist locked a boy inside a leisure centre toilet cubicle and raped him, a court heard.

Psychotherapist Nicholas Gully, 47, is accused of attacking the 14-year-old boy at King Alfred Leisure Centre in Hove as he waited for his mum to pick him up.

The jury at Hove Crown Court heard that the boy had been to the gym on January 29 this year.

The prosecution said Gully, who lives in Rottingdean but is a sex addiction specialist at the Brunswick Clinic in London, followed the boy in to the leisure centre bathroom after staring at him outside while he was on the phone.

The teenager had been waiting for his mother to pick him up when he decided to go to the toilet.

The jury was played the teenager’s police interview, during which he said: “He casually walked into my cubicle as I opened the door and he locked the door behind him. I am not sure if there was someone else in the bathroom.

“He asked me to take my trousers down and I did.”

He told police that Gully then said that he was going to perform a sex act on him.

“I felt paralysed. I was scared,” he said in the police interview.

He said Gully orally raped him, adding: “He was quite rough with his hands and to get away I leant down and stood back.

“Next he pulled his trousers down...nothing was said apart from him saying ‘shush’.

“I stood back up and he started on me again.

“I felt ashamed I suppose because it was the first time it had happened. After it happened he still seemed really keen.

“I just felt disgusting. Then he leans forward and starts kissing me. He was also licking my chest.

“My mum tried to phone me during this. After that, I said to him I needed to go and then left.

“Because he was on the phone to someone before I went into the toilet and had said something on the phone about a sexy boy being there, I was worried someone would be waiting outside.

“I waited for someone to leave [the leisure centre] so I could walk out behind them.

“I was so shook about what happened.”

The court heard that the boy was then picked up by his mother in the early afternoon.

The prosecution said he phoned his friends to tell them what had happened before later telling his auntie, who told his parents.

By this point he had called police, the prosecution added.

Gully, of Eley Crescent, Rottingdean, denies two counts of sexual assault and one of rape.

The trial continues.
