TERRIFIED women were raped and beaten by violent Paul Lewis, a court heard.
The 32-year-old, of Bristol Road in Gloucester, forced the women to have threesomes with each other and even another man.
He was found guilty of three rapes, four counts of causing a person to engage in sexual activity and five charges of causing actual bodily harm.
During a two week trial, Gloucester Crown Court heard Lewis was controlling and violent towards his three victims.
The women from Bristol and Gloucester, all aged under 35, said they were punched, kicked and threatened by Lewis if they did not do what he wanted.
The court heard they were frightened into having threesomes with each other and in one case, another man, and Lewis used his power to control them and cause the women to fear him.
Prosecutor William Moorehouse told the court at least one of the women had worked as a prostitute – but stressed that they should be given the protection of the law.
He said: "If a woman is terrified of the consequences of not going along with what he wants, then her consent cannot be given.
"We say the women did not have the freedom and capacity to make that choice.
"I don't pretend to present any of these women as Maria from the Sound of Music, but these women are fragile, damaged and vulnerable.
"How they have conducted themselves does not mean they should be disenfranchised from the criminal justice system and despite their pasts you can believe what they say."
Lewis claimed the women came together in a bid to conspire against him and made up the allegations.
He was found not guilty of one count of rape, one of causing actual bodily harm and another of causing a person to engage in sexual activity.
A further charge of actual bodily harm was withdrawn by the prosecution.
Further allegations of kidnapping, actual bodily harm and raping a fourth victim will remain on file, as will an attempted robbery.
A charge of kidnapping in connection with the case against Mark Long, 43, from Shakespeare Avenue, has also been ordered to lie of file.
Lewis has been remanded in custody and will be sentenced at Gloucester Crown Court on June 21.
