A showjumper accused of having a threesome with a fellow rider and an underage girl had a 'mutual understanding' with his girlfriend he could have sex with other women, a court has heard.
Guy Simmonds, 37, and Rebecca Dimes, 34, agreed they could sleep with other people in their relationship as long as she 'did not want to know anything about it'.
The horse-riding instructor and fellow rider Lauren Jarvis, 26, are alleged to have had sex with the schoolgirl last year, despite knowing she was under 16, and agreeing to a 'pact of silence'.
The court heard there had been a 'clear element of grooming behaviour' from the 37-year-old before the alleged threesome took place, even though he had 'no doubt at all' about the victim's age.
It was previously heard Simmonds called himself 'daddy' in messages to the youngster and would also use a horse trailer to have 'repeated' sex with her while Miss Dimes was away.
