Former U.S. Rep. Anthony Weiner has been accused of sexting an underage high school student.

A 15-year-old girl and her father told The Daily Mail that she had an online sexual relationship with Weiner, 51, that lasted for months last year. Sexually explicit messages sent through apps like Twitter, Facebook, Kik, and Confide included photos of his bare chest and requests to role play with her in "school girl" outfits with him pretending to be her teacher.

"He had some rape fantasies. It would just be him showing up at my house when my dad was out of town," the girl, whose name is being withheld because she's a minor, said. "And just start undressing me, being forceful, asking me if I want to be dominated, strange questions."

The New York Post reports they also chatted on Skype, where Weiner asked her to undress for him.

Weiner knew the girl was a minor, she told the Daily Mail. She first contacted him through Twitter in January 2016, when she was a sophomore.

According to the publication, the girl admitted she was "obsessed" with Weiner and wanted to write a book about him. "You were my Hannibal Lecter," she allegedly told the former Congressman.

The explosive accusations follow another sexting scandal last month when a woman revealed Weiner had sent her a photo of himself in his underwear as his 4-year-old son could be seen sleeping in the background. Weiner's wife Huma Abedin, currently campaigning for Democratic presidential candidate Hillary Clinton, separated soon after and child welfare officials launched an investigation against Weiner.

The one-time New York City mayoral candidate resigned from Congress in 2011 after posting a lewd photo of himself on Twitter, initially claiming he had been hacked. He later admitted he had been inappropriately tweeting several women, including Sydney Leathers, and confirmed the picture in boxer briefs was his.

Abedin was pregnant when the first scandal ended Weiner's time in Congress. In 2013, she stood by his side as he claimed therapy had helped change his ways.

His attempt at a political comeback failed later that year when more women came forward, claiming he sexted them under the pseudonym "Carlos Danger" as he ran for mayor.
