A woman who told police she wanted to be a "cool mom" by partying with teenagers pleaded guilty to sexual assault Monday.
Forty-year-old Silvia Johnson also could face up to 58 years in prison for having sex with high school boys at parties where she supplied drugs and alcohol.
Johnson pleaded guilty to two misdemeanor counts of sexual assault and nine felony counts of contributing to the delinquency of a minor.
As part of a plea agreement, prosecutors dropped two counts of distribution of methamphetamine.
According to an arrest affidavit, Johnson held parties for the boys almost weekly between October 2003 and October 2004. The affidavit accused Johnson of providing drugs and alcohol to eight boys and having sex with five of them.
Johnson is free on bail and her sentencing is scheduled for September 26th.
