A mother has been arrested after she threw a "naked Twister" party for her teenage daughter before having sex with two of her daughter's friends.

Rachel Lehnardt, 35, told police her 16-year-old daughter sent her a text message asking if she could bring friends home to "party" and she replied "come on, let's party".

The party at Ms Lehnardt's home, in the affluent suburb of Evans in Augusta, Georgia, involved alcohol and marijuana before the group decided to play a game of naked Twister.

Police allege that Ms Lehnardt told her Alcoholics Anonymous (AA) sponsor last week that she went to the bathroom with an 18-year-old friend of her daughter and had sex with him.

Ms Lehnardt reportedly also told her AA sponsor she still felt "horny" afterwards and masturbated with sex toys in front of her daughter and her friends.

The party moved to the jacuzzi before the mother-of-five passed out in her bed, the police report said.

The bridal shop employee woke up at around 3.30am to find her daughter's 16-year-old boyfriend having sex with her, the AA sponsor said.

The teenager is not facing rape charges as police said there is "no evidence" due to Ms Lehnardt's refusal to discuss the incident.

Ms Lehnardt was arrested on two counts of contributing to the delinquency of a minor and was released on $3200 bond, police said.

Someone close to Ms Lehnardt told New York Daily News the alleged rape made her realise her drinking, which started in November when her marriage ended, was a problem.

The party also led to Ms Lehnardt losing custody of her five children aged four, six, eight, 10 and 16, on April 16.

The 35-year-old was raised as a Mormon and had reportedly never touched a drop of alcohol before her ex-husband came back from Iraq with Post-Traumatic Stress Disorder and anger issues in 2010.

Ms Lehnardt's lawyer said some of the accusations were "exaggerated" and it was a "difficult situation for the entire family".
