Arrest: Rachel Lehnardt, 35, allegedly threw a drunken party for her 16-year-old daughter . A mother-of-five threw her teenage daughter a party, played naked Twister with her friends and then had sex with an 18-year-old in the bathroom, authorities have said. Rachel Lynn Lehnardt, 35, from Evans, Georgia, was arrested on Saturday night and has been charged with two counts of contributing to the delinquency of a minor. The details of the drunken party emerged when Lehnardt met with her Alcoholics Anonymous sponsor last Friday and told her about the wild party. The sponsor then contacted authorities. She told the woman that her children, who are aged between four and 16, were with their father when her oldest daughter texted her to ask if she could bring over some friends. Lehnardt allegedly responded: 'Come on, let's party', WJBF reported. When the teenagers arrived, she allegedly allowed them to drink alcohol and smoke marijuana in her home, before she played naked Twister with them in the living room. While the youngsters continued playing, she allegedly went into a bathroom and had sex with an 18-year-old man, the sponsor told authorities. When she returned, she brought out sex toys and started to use them on herself in front of the teenagers, she told her sponsor, Augusta Crime reported. Party: The mother-of-five allegedly played naked Twister with her daughter and her friends before having sex with an 18-year-old male in the bathroom. She later had sex with her daughter's 16-year-old boyfriend . She later went to bed alone and around 3.30am, she awoke to find someone having sex with her, she told her sponsor. 'She stated at first she thought it was the 18-year-old from earlier, but then realized it was the 16-year-old who was in fact her daughter's boyfriend,' Lehnardt's sponsor told deputies. The daughter told her mother she felt guilty because the boyfriend's 10-inch penis was so large she could not have sex with him, and he needed to have sex with her mother instead. While the incident sounds as if the 16-year-old raped the mother, Sheriff's spokesman Captain Steve Morris said there was no evidence of a crime and no charges are pending against the boy. No sexual crime charges have been filed against Lehnardt because 16 is the legal age of consent. Lehnardt also allegedly told the sponsor that she had shown her daughter explicit photos, including of Lehnardt having sex with her boyfriend. The sponsor said that the mother has also previously spoken about being a porn addict. Scene: She allegedly threw the party at her home in Evans, Georgia, pictured, and lost custody of her children after the incident. She has been charged with two counts of contributing to the delinquency of a minor . Following the incident, an emergency custody hearing was held and she lost custody of her five children, who are aged four, six, eight, 10 and 16, WJBF reported. At their meeting last week, the sponsor asked Lehnardt how long she had been sober and her future plans for sobriety, and the mother told her about losing custody of the children days before. After their meeting, the woman, who was only recently assigned to sponsor Lehnardt, contacted the Columbia County Sheriff's Office and the mother was arrested on Saturday. She has been released from the Columbia County Detention Center after posting a $3,200 bond, according to the Columbia County News-Times. According to online profiles, Lehnardt crafts and paints dolls. The children's father is in the military. Lehnardt was arrested after sharing details of the incident with her Alcoholics Anonymous sponsor, who then went to authorities. As part of the AA's 12 Step program, members write a list of incidents they feel guilty about and confide in their sponsor about the acts (known as the Fifth Step). The person is then required to make amends for past wrongdoings, as long as doing so does not cause harm to others. While there is an expectation of anonymity at meetings, there is no guarantee, and experts recommend exercising caution when detailing crimes, according to The Fix. AA literature simply states that 'anonymity provides protection for all members from identification as alcoholics'. The main 'Understanding Anonymity' booklet does not mention safety from disclosure of a crime and there have been multiple cases of AA members being convicted of crimes, including, murder after confessing to their sponsors. But there has also been some debate over whether the confessions can be used in court. In 2001, a 1995 murder conviction was thrown out after it was ruled that a killer's confession to fellow AA members was constitutionally protected and shouldn't have been used against him. The decision was reached after the judge deemed the 12 Step program had religious undertones, meaning that the members engaged in  religious activity, which is constitutionally protected.
