If you've been keeping track of the Russell Simmons' sexual assault saga, now 16 women have accused the Def Jam founder of sexual assault or rape.

The 16th accuser, who's also suing Simmons for $10 million, has quite a story to tell.

"Jane Doe" says Simmons met her at a Def Jam concert in Sacramento, California that she had chaperoned her elementary school-aged son to.

He invited her to an afterparty, so she dropped her son at home with a babysitter. They then met at a hotel bar, and he said he wanted her to come up to his room so he could get something. Doe says Simmons assured her that he wasn't interested in sex because he was dating a well-known model. (It's unclear when the incident took place.)

But, once they got to the room, things changed.

"After entering the room, Simmons shut the door and said 'I am going to f**k you.' Plaintiff said she had no intention of having sexual relations with Simmons -- but he replied 'I am going to f**k you or I'm going to f**k your son. You decide," a document filed by her attorney Douglas Mastroianni states.

Simmons then threw her on the bed and raped her.

Simmons has denied all the charges against him, including this latest:

"I vehemently deny all the allegations made against me. They have shocked me to my core as I have never been abusive or violent in any way in my relations with women. I have submitted myself to multiple lie detector tests," he told TMZ. "I denied forced sex and sexual harassment allegations brought against me in each test; I also answered no to the question, 'Have you ever physically forced any woman to have sexual intercourse?' I passed all of the lie detector tests."

Do you think all 16 women are lying?
