A showjumper has been accused of 'pestering' a female rider for sex in exchange for free lessons - before the pair then went on to have a threesome with an underage teenager just months later, a court has heard.

Horse-riding instructor Guy Simmonds, 37, began flirting with fellow rider Lauren Jarvis, 26, when she attended his yard for a lesson with her horse.

A court heard Jarvis said Simmonds told her: 'I wish you would ride me like you ride your horses.'

She received WhatsApp messages from Simmonds on the same day as the lesson asking her for 'inappropriate images.'

Giving evidence, Jarvis said: 'He was trying to get me to send him inappropriate images while I was in a relationship with my boyfriend. It was the same day I had the riding lesson.
