A TEACHER accused of having sex with a teen pupil in a plane toilet has told a court it would have been "impossible" — because she was wearing hiking boots.

Eleanor Wilson, 29, described claims that she pulled one leg of her trousers down to romp with the 16-year-old on a flight back from a school trip to Africa as "like the description of a weird porn film".

She is facing four charges of abuse of position and sexual activity with a child following the alleged tryst on the BA plane in 2015 when she was 26.

Wilson today told Bristol Crown Court that the size 10 boots she was wearing during the flight would have made it impossible to take her trouser leg down as the teen claims.

She told the court: "There is no truth whatsoever — you'd have to take boots off first to get trousers off."

And she slammed the allegations as like a script from "a porn film."

In a police interview played in court, she added: "It's come from his imagination.

"The other staff there would say that wasn't happening. It makes me feel sick, the idea of it.

"I would not done any of that. I would not have broken the law or gone beyond a friendship.

"I’m in a relationship, he’s a student — I would have not gone there at all."

In court, she said pupils were regularly "coming and going" from the plane toilets on the return flight — leaving no opportunity for the alleged illicit encounter.

Recalling an encounter with the boy on the flight, Wilson told jurors she was sitting on a ledge outside the toilet when the teen claimed their sexual interaction started.

Wilson told the court the boy had been drinking and asked her: "What's going on, why are you sitting here?".

She added: "He was stood in front of me - people were coming and going to the toilet.

"He was there for 10 to 15 minutes and we spoke about what he was looking forward to when we got home.

"He sat next to me but not on me — I would never touch or kiss him."

Wilson also told the court that she was on her period during the flight and having sex with the pupil was "the last thing I was thinking of".

The teacher, from Dursley, Glos, admitted sending "flirty texts" to the teen following the flight encounter.

The court told the pair exchanged 295 texts and 23 calls over the following eight months.

She said she was an "idiot" to give the teen her mobile number — which he saved in his phone under the name "Smurfette".

The former teacher also admitted to going on outings with the boy including to Tintern Abbey in Wales but denied ever kissing him.

She said the trips were an opportunity for her to have a day out because the boy "was really the only person I had that was a friend."

The alleged fling was exposed when a jealous friend of the victim tried to blackmail Wilson into having sex with him, jurors heard.

Wilson said she had a good relationship with her boyfriend, and would not have looked for a companionship anywhere else.

Instead, she described the teen, who cannot be named, as a "mate" and had once tried to comfort him as he cried.

She recalled making him laugh when she joked: "Girls don’t go for crying boys."

The former teacher, who is now a civil servant, said the pair had become close, and found him “quite a charming, cheeky chap”.

Wilson also admitted she told him she was pregnant as she was "lonely and upset".

She said she had an abortion — but did not tell her boyfriend at the time.

Her former boyfriend Andrew Hall yesterday told the court that the couple only had sex once every six months — meaning it was unlikely she would have been pregnant with his child.

The student has claimed the teacher told him she was pregnant with his child after they had unprotected intercourse on the flight home from Swaziland.

The jury was told the teacher booked an appointment on September 10, 2015, and had an abortion 14 days later.

But Wilson claimed that she was on her period on the flight home from the school trip — meaning she couldn't have become pregnant even if the encounter with the student took place.

The court had previously heard the student's description of the alleged sexual encounter on the plane with his then 26-year-old teacher.

In a police interview played to the court, the boy said: "She ran her hand around my penis.

"I was wearing jogging bottoms. I carried on and then she slid her hand down my boxers, there was a little foreplay.

"That went on for a bit. Then she proceeded to go into the toilet. She called me in. I walked in closed the door and locked the door.

"We proceeded to kissing and touching and at this point she had my hand down her boxers.

"From there, she pulled down my jogging bottoms and she was placed on her knees.

"My back was against the wall and she was knelt in front of me. Then when she stood up my trousers were down anyway and she pulled her trousers down.

"It became difficult it wasn't working — she's very tall."
