A rapist who assaulted a woman in her own home whilst her child slept in the next room has been jailed for 10 and a half years.

Matthew Cawston knew his victim and had visited her home to help with a domestic emergency, Preston Crown Court heard.

However, when the job was finished, the 27-year-old complained he didn't want to cycle home in the rain and asked if he could stay over, according to Lancs Live.

Paul Treble, prosecuting, said the woman agreed to let him sleep on the sofa, but made it clear to him that she did not want to have sex.

The woman went to bed and left Cawston on the couch, but later woke to find her pyjama bottoms had been removed and Cawston lying on top of her having sex.

In a statement, she told police she 'froze', adding: "He was trying to be as gentle as possible and as quiet as possible so as not to wake me."

Cawston left the house the next day, leaving his victim unsure how to deal with what had happened to her.

A few days later she texted him, asking: "Why did you do it? You had sex with me while I was asleep?"

The defendant replied: "I was horny. Sorry." and asked if she was going to report him.

The woman later told a college tutor and then the police.

Cawston, of Hoyle Close, Blackpool, was arrested and insisted he had never had sex with the woman without her consent.

However he later pleaded guilty to rape.

In a victim impact statement, the woman said she suffered nightmares and flashbacks and had felt she had to move house following the attack.

She no longer invites visitors into her home and does not feel safe going out.

She said: "Because he was sexually frustrated he has completely destroyed my confidence and trust in people and seriously affected my mental health.

"I can never put into words the true effect this has had on me, my daughter and my family, and will continue to have for a very long time - possibly forever."

Since the attack she has started self harming and has spoken to family about who would care for her daughter if anything happened to her, Mr Treble told the court.

Barbara Webster, defending, said Cawston has Autistic Spectrum Disorder and receives support from a social worker.

Ms Webster said: "It does not excuse what he did but it gives an insight into his behaviour."

Sarah Armstrong, a social worker, said Cawston had "difficulties understanding relationship boundaries" and was "significantly exploited by people, both financially and materialistically, who he considered friends."

She said her team had been working with the defendant to identify positive behaviours and reinforce boundaries for personal safety.

When Ms Webster spoke to the defendant before the sentence hearing, she read him the victim impact statement and asked him what he thought.

Cawston replied: "I am so, so sorry for what I did."

Judge Sara Dodd, sentencing, said: "It is very clear to me that this offence has had a great impact on your victim...

"She described feeling like her life is on hold and can't move forward until justice is done. I have also to consider the fact you are still a very young man and you have no previous convictions. Your own mental difficulties, your autism, no doubt played a significant part in your offending. I accept your remorse in this case is genuine."

However she said Cawston posed a very real risk to adult women he was in a relationship or friendship with.

Judge Dodd sentenced Cawston to ten years and five months, comprising of six years and five months in custody and a four year extended licence.

He sobbed as he was led away to the cells.
