An alleged predator raped a teenage girl so violently she passed out before he carried on, a jury was told.
Mark Aspin, 44, beat a total of three victims before using them for sex in front of his girlfriend, Grimsby Crown Court heard on Monday.
During one alleged attack, Aspin, from Grimbsy, is accused of raping a teenager so aggressively that she lost consciousness.
Jurors were told that the incident was watched by his partner, Debbie Pickersgill, 46, who has claimed she feared being attacked herself.
When the girl woke up Aspin is alleged to have said “oh she’s alright” before carrying on, Hull Daily Mail reported.
Aspin and Pickersgill have been charged with 27 offences between them, including child cruelty, engaging in sexual activity with a child and making indecent images of children.
The court was told that when the allegations were first reported to police Ms Pickersgill was initially treated as a victim, rather than a suspect.
Ms Pickersgill told police when she was interviewed in April this year how she would regularly hear Mr Aspin having sex with teenage girls and would be forced to engage in threesomes with them, scared Mr Aspin would beat her.
From the witness box, an inspector from Humberside Police's Protecting Vulnerable Person's Unit read out evidence from Ms Pickersgill's first police interview.
In it she alleged that Mr Aspin tracked her phone and she "could not tell anyone what was happening," even after Mr Aspin admitted having sexual intercourse with a young teenage girl, who he would also beat.
She said: "Sometimes I could hear him beating her up and having sex with her. I was too scared to do anything. I could hear him hitting her and her screaming."
Ms Pickersgill told police how she would engage in threesomes with her then-partner and the girls out of fear of what he would do to her if she did not comply.
She said: "He would make me kiss and touch her [one of the victims]. She [the girl] didn't say anything, she just complied with whatever was going on.
"Sometimes the covers would go over her and he [Mr Aspin] would ask, 'Are you doing it?' and I would say yes but I wasn't. I felt sick.
"He had sex with her when I was there. It would happen once a month but I would try and persuade him not to. I used to pretend I was asleep but he would just wake me up."
Ms Pickersgill told police she was terrified of what would happen to her if she ever reported the alleged crimes.
She said: "He would beat me up even when I made a cup of tea wrong. I could never do anything right. I hated him for what he was doing to me and I wanted to escape. I was scared I was going to be killed."
The court heard how Ms Pickersgill had once attended a women's centre and the police were called following an incident where Mr Aspin had turned violent. He was arrested but Ms Pickersgill withdrew her statement.
Less than 48 hours after her initial interview with the police in April this year, she was interviewed again as a suspect.
The trial continues.
