Gym teacher William ‘Bill’ Barber allegedly seduced a 15-year-old student on Twitter before taking her virginity

A MARRIED father-of-three with one on the way has been arrested after the popular gym teacher seduced a student, 15, on Twitter before having sex.

Pennslyvania man William “Bill” Barber is well-known in his town as the father of a four-year-old girl battling cancer who has created the viral “lemon shot challenge” to raise funds to help raise funds for his daughter.

NBC Philadelphia says the Delaware county has been rocked by news that Barber, who coaches football and baseball at Gaet Valley Middle School, allegedly took a 15-year-old student’s virginity.

Pennsylvania State Police Corporal Gerard McShea said the girl had sent Barber nude photos earlier this month on Twitter.

An affidavit states that Barber said to the girl, “wow you are a very sexy young lady”.

He then went on to say “you could have been here but it’s all good. I shouldn’t tempt myself anyway.” About half an hour later he followed up the message, by telling her “your body drives me crazy.”

Barber and the girl allegedly met in his office earlier this month where they began kissing and then moved to a back room where they had sex.

In the affidavit, the teen said the intercourse did not last long because she was in a lot of pain as it was her first time.

Gaet Valley School District Superintendent Dr Marc Bertrando said that Barber had been suspended on pay and asked Monday night to tu in his keys.
