The four defendants, Norman Macksoni, 48, Richard Wilkins, 62, Connor Sanderson-Doyle, 32, and Mohammed Hassan, 38, each deny sexual assault charges. Sarah Jones KC, prosecuting, told the jury the case centred on whether it was "ever reasonable" to have sex with an unknown woman without checking with her first.
Ms Jones said Philip Young posted adverts on swinging forums inviting strangers to "come and sleep with his wife at any age, any grace". Joanne Young, who has waived her anonymity, had described her sex life as "fairly normal" and told her husband 15 years ago she would never want to sleep with anyone else. The prosecution said Young drugged her to "plunge her into a state where anything could be done to her by whoever answered".
The first indication of the abuse came in 2023 when, during blindfolded sex with her husband, Ms Young became aware of someone else's hand touching her wrist. The following morning, Young apologised and said he had invited someone to watch.
Police began investigating after images were uploaded to social media. A packet of sedative drugs mailed from India to Young was intercepted. Ms Jones said Ms Young was exposed to sedative drugs over an 18-month period from April 2023 to August 2024, entirely unaware.
Judge Mr Justice Saini warned jurors they would see graphic evidence and told them to approach matters "using common sense and logic". The trial continues.
