Boy, 15, 'given drugs to stay awake for sex by mum-of-three accused of threesome with teens' 18:05, 5 Jan 2016 Updated 19:44, 5 Jan 2016 By Kim Pilling The defendant denies committing any sexual offences and told police that the threesome allegation was "nonsense" Defendant: Caroline Lea appeared in court looking drawn A 15-year-old boy was given drugs by a 36-year-old mother-of-three to keep him awake for sex, a court has heard. Caroline Lea is said to have slept with the youngster on a regular basis for several months before he said he realised he needed to find a girlfriend of his own age. The defendant, from Blackpool, Lancashire, is also accused of taking part in a threesome with another 15-year-old complainant and his young friend, as well as allegedly sexually touching a third boy of the same age. A jury at Preston Crown Court today heard evidence from her accusers including a youth who said Lea initiated their first sexual encounter by inviting him to her bedroom to watch a film. In his police interview, the complainant said he was "shocked" and pushed Lea away on her bed when she tried to kiss him but then "changed my mind because I'm a lad". He said the defendant performed oral sex on him before they had intercourse in several positions. Julian Hamilton/Daily Mirror Accused: Caroline Lea outside Preston Crown court in Lancashire He said: "We did everything really. "Everything you name, everything she wanted to do." The interviewing detective asked him: "What ended that first sexual encounter?" The teenager replied: "We stopped because we were tired." The sexual relationship continued as he stayed over at her former home in the resort, the court was told. He added: "Sometimes I was a bit tired and she would give me speed (amphetamines) to stay awake." He said the defendant was usually sober during sex except for one occasion. Asked what made him decide to stop the alleged relationship, he said: "Because it was wrong, because I'm 15. "I have a life ahead of me. "I have got to go out and get a girlfriend of my own age." He said he also listened to the advice of his friends who told him the defendant was "ruining" his life. Lea is also accused of having a threesome with another 15-year-old boy and his young friend. One of the complainants told police his friend suggested "a three-way" with the defendant and then it "just happened". Julian Hamilton/Daily Mirror Denial: Lea has pleaded not guilty to all counts He described how the trio went to the upstairs bedroom of Lea, who then laid on the bed wearing pyjama shorts and a vest top. As the then 15-year-old and his friend sat on her settee for five minutes, he said Lea told them: "Come on boys, I thought you knew what you were doing." Both went on to have full intercourse with the defendant, according to the complainant, and she allegedly also performed oral sex on the pair. Cross-examined by defending barrister Rosalind Emsley-Smith, the youth - giving evidence today via video-link - admitted he told friends about the alleged threesome but denied he bragged about it. He denied he had any discussions about a claim for compensation. He also denied that he was asked "fairly regularly" to leave the house when he visited and that he would climb through windows to get back in. He also disagreed with the barrister's suggestion that he had the "capacity to be threatening or aggressive if things would not go your way". PA Trial: Preston Crown Court, where the case continues After he was asked to explain how the "threesome" happened, Miss Emsley-Smith said to the complainant: "The reality of this is that you are struggling to remember the details of this event to the jury because it did not happen." The witness replied: "It did happen." He had told the jury that he had sat on a black leather two-seater settee in her bedroom before sex but Miss Emsley-Smith said that detail was not correct and was "part and parcel of the lie you are telling". The youth said: "Well, I'm not telling a lie. Lea, of Clifton Drive, denies seven counts of engaging in sexual activity with a child on various dates between December 2013 and March 2014. She has also pleaded not guilty to one count of allowing her home to be used for smoking cannabis and a separate count of supplying amphetamines, a Class B drug, to another. The case continues.
