Four couples took over a quiet cul-de-sac in rural Wales and set-up a sex cult after moving from London, a jury heard.
Leader Colin Batley, 48, allegedly used four women to find him victims while organising three-in-a-bed sex sessions.
He used his position to rape both boys and girls, to make children engage in intercourse together and to persuade the women to join in, the court was told.
The grey-haired man, described as 'evil and manipulative', was allegedly a sexual predator who used others to do his bidding.
Batley even persuaded three women to get identical tattoos to show their membership of the cult in the seaside village of Kidwelly, near Carmarthen, the jury at Swansea Crown Court heard.
Peter Murphy, prosecuting, said Batley held regular meetings of the 'quasi-religious cult' where he preached from a text called The Book of the Law and warned of dire consequences if the women did not do as told.
He said: 'He (Batley) is the principal. The four families became closely intertwined, that is common ground. It became much more than that, a cult.
'The usual restraints went out of the window. Some took part in wife swapping.'
In 1995 Sandra Iveson, 49, moved into the quiet street before the others moved in over the next four years.
Defendants Batley and his wife Elaine, 47, Jacqueline Marling, 42, and 35-year-old Shelly Millar all got properties in the street.
Mr Murphy said one teenage girl would tell the court later how she attended a Halloween party and saw two women performing oral sex on two men.
A teenage boy would say he had a 'threesome' with Elaine Batley and Jacqueline Marling, and intercourse with Shelly Millar, all before he was 16.
Batley and Marling admitted having sex with the youth but claimed it had been a 16th birthday present, the prosecutor said. Millar denied ever having sexual intercourse with him.
Another girl allegedly had a threesome with Colin Batley and Jacqueline Marling.
On a separate occasion Batley made a 16-year-girl have sex with a boy of 15 while Marling filmed it on a camcorder, it was alleged.
Mr Murphy said in 2000 Colin Batley travelled to Bedfordshire to advise the daughter of a cult member about her marital problems, and had sexual intercourse with her before returning to Wales.
The five defendants deny a total of 33 charges, including rape, indecent assault, forcing a girl to work as a prostitute and inciting a child to have sex.
A sixth defendant, 70-year-old Vincent Barden, from Kempston, Bedfordshire, has admitted twice indecently assaulting an underage girl but denies rape.
The trial continues.
