Her crime? Wetting herself because she was too afraid to use the toilet - in case it woke her parents up during the night.
Lily - whose name has been changed - was 18 months old when her evil family began their torturous campaign of violence.
Over two decades, she was routinely sexually abused by both parents, which led to her being forced to give birth to two of her stepfather's children.
Her so-called caregivers finally faced justice in 2016, when her stepfather was sentenced to 25 years in prison and her mum received just 18 months.
Now 40, Lily, from Hampshire, told The Sun: “One of my first memories was flashing lights over my head and scans being taken.
“My stepfather was forced to take me to hospital after I was found black and blue. I was only three or four years old.
“When I was 15, he started raping me regularly and wouldn’t let me leave the room until he had taken out his anger.
“I used to cry my eyes out and beg my mother not to let him do it, but she told me, ‘It’s you he wants, not me’ and later she took part in the abuse too.
“From 18 months old until 22 my life was hell, but suddenly a switch went off in my head. I didn’t want these four walls to be permanent, I needed to and would escape.”
'Not enough is being done'
Lily is bravely speaking out as MPs approved Tony's Law yesterday, which will allow judges to sentence child abusers to life imprisonment.
It followed the case of Tony Hudgell, who lost both of his legs after being tortured by his mum and her boyfriend but only received 10-year sentences.
There's also a worrying spike in reports of child neglect and abuse, which rose by 22 per cent last year, according to the ONS.
The NSPCC warns more kids will be at risk without vital amendments to the Health and Care Bill, which reorders safeguarding structures and information sharing.
Vicky Nevin, senior policy officer at the charity, told The Sun: "It’s crucial that social workers, the police and health professionals can see the full picture about what is going on in a child’s life.
"That’s why joint working is so important to respond to concerns about abuse, and to help children and families before they reach crisis point."
Lily knows the risks of this all too well, having being returned to her abusive household.
She says: “The Government can’t ignore what’s going on any longer.
“I could have died because not enough was being done in the Eighties and there is still not enough now to the current day. Our voices are not being heard.
"We need all authorities to come in line and work from the same spreadsheet - not enough is being done."
Beaten black and blue
Lily was three years old when a worried neighbour called the NSPCC after hearing her “banging on a window inside a locked room” and spotting her swollen face.
She recalls: “I was beaten black and blue and they were really concerned because there were suspicious marks - not bruises I could have made myself."
An NSPCC officer forced Lily's parents to take her to hospital where they found intense and old bruising, skull trauma, a damaged eye socket and internal bleeding.
She stayed in hospital for two weeks and was with a foster family for six months before being returned to her mother and stepfather.
This came in spite of her claims the NSPCC, argued she was in "extreme danger” and.ily was sent back after the courts ended a child cruelty case against her parents - allegedly because evidence from her doctor, who was on holiday, was not filed in time.
Returned to rapist stepdad
Within two weeks, Lily was being beaten regularly again and by 11, she was asked to strip off in front of her stepfather, which led to the abuse turning sexual.
At 14, he pinned her to a sofa and raped her.
She recalled: “He had this horrible grin on his face and said, ‘I don’t know why you’re behaving like this? All the other girls your age are having sex.’”
Lily became pregnant at 16 and to cover it up, her family claimed she had a one-night stand with a local builder.
She was groomed to “take over" her "mother's role” – forced to clean the house or face physical violence - and was raped regularly.
If Lily “missed a speck of dust” her stepfather would grab a “hairbrush, hoover pipe or anything he could get his hands on” and strike her.
She became pregnant with her second child at 18 and it took another four years until she finally felt able to escape from her tormentors.
It followed a “very serious attack” where her stepfather “knocked a tooth out” and strangled her until she fell unconscious.
The next morning, she watched a piece about domestic violence on ITV's This Morning and jotted down the number for a helpline, summoning the strength to seek help.
I didn’t think anyone would believe me because it was like something from a film not real-life
Lily moved between women’s refuges, but her stepfather kept finding her.
“Even when I escaped, my stepfather wouldn’t leave me alone, he kept finding me and I thought we was going to kill me if I didn’t return," she says.
Lily battled with booze, drugs and self-harm as she tried to deal with the horrific ordeal.
It took many more years for her to feel able to talk to police about what happened, but in 2016, her mother and stepfather were taken to court.
He was jailed for 25 years after being found guilty of indecent assault, cruelty to a child and ill treatment, attempted rape and three counts of rape.
But her mother only received 18 months for ill-treatment due to being “traumatised” by her partner's abuse.
“When the verdict was announced I never cried so much in my life. It was overwhelming because I didn’t think anyone would believe me because it was like something from a film, not real-life,” Lily recalls.
Now a happily married mum-of-four, she has found peace in recent years and wrote her memoir Hidden Torture: A Face Behind A Masquerade Mask.
Mental health workshops at the Isorropia Foundation, where she is now a mentor, were “life-changing” and rebuilt her self-esteem and confidence.
“I’ve learned to love myself and found happiness, now I look forward to the future with my friends and family,” Lily says.
“I’m not that little girl or people who was abused or raped, I will not give them that satisfaction of taking any more of my time or energy.”
