The horrified victim awoke to find Chantae Gilman, 28, who weighs nearly 16 stone, on top of him while holding his hands above his head
A woman tried to rape a sleeping man after breaking into his apartment during the middle of the night.
Chantae Marie Gilman, 28, admitted attempted rape and assault charges but said she didn't know the victim and has no recollection of what happened.
The mum-of-three, who claims she suffers from bipolar disorder and psychosis, climbed into the victim's bed while he was sleeping.
Detective Roger Ishimitsu reported: “Once arriving home he fell asleep on his bed (and) slept very hard due to a long day.”
The victim told police he woke at 2am to find Gilman, who weighs nearly 16 stone, on top of him having sex, while holding his hands above his head.
He then demanded Gilman get off and leave, but she refused and told him to be quiet, according to the police report.
The man, whose identity is protected, then managed to wriggle free and kick her out of the apartment after the attack in June, 2013.
Gilman, from Washington, US, carried on knocking on the door but the victim refused to open it and she soon left.
Later that day he visited the police station in, Seattle, Washington, before undergoing a full sexual assault examination, where officers extracted Gilman's DNA.
Detective Drew Fowler, with the Seattle Police Department told Komo News: "From a statistical standpoint, yes, it is atypical to have a female aggressor.
"But we work to hold all people responsible for their actions. The law is specifically written to be gender-equitable and we will charge anybody with a crime that they've committed."
Gilman pleaded guilty to both charges and is due to be sentenced on June 19.
Her plea deal requires her to serve two years probation upon release from custody.
