An Allentown woman accused of sexually assaulting a 13-year-old boy last year testified on Tuesday it was the accuser who attacked her, and she was the victim in the case.

Rachel Warris' trial on charges including involuntary deviate sexual intercourse and indecent assault began Tuesday morning in Lehigh County Court.

Warris took the witness stand in her own defense Tuesday afternoon.

Wearing a blue and white striped dress and a tan jacket, Warris said it was the accuser who attacked her on Feb. 11, 2015. The boy pushed his penis in her face, she testified, and she had to bite the boy to get him away.

Warris said she was scared, and didn't want to hurt the boy, but wanted him to get away from her.

"You're saying you were raped, right?" asked Lehigh County Senior Deputy District Attorney Anna-Kristie Morfi Marks.

"Yes," Warris said.

Marks asked if Warris was claiming she was the victim in the case.

"Yes," Warris answered.

Warris, who is 40, admitted she exposed her chest to the boy about six months before the Feb. 11 incident.

"That's not what adults do in front of children, would you agree?" Marks asked, and Warris agreed.

When Warris testified she wanted to be "just a friend" with the boy, Marks read the explicit Facebook messages the woman sent to the boy. They included the Spanish expletive for having sex; Warris said she used Google translate to find the right term.

Before the Feb. 11 incident, Warris allegedly barraged the boy with Facebook messages, asking him to add her as a friend. After the incident, Warris messaged the boy not to disclose it, and sent him images of hearts and "I

The alleged messages were discovered by the boy's mother, who confronted Warris, and then went to the police.

Referring to the text messages, defense attorney David Ritter said it was "inappropriate behavior" but not evidence of his client's guilt in the case.

Attorneys are expected to make their closing statements on Wednesday. Warris, of the 600 block of Dixon Street, has been free on $50,000 bail in the case since April.
