A head chef for P&O Ferries died during a kinky sex game after being wrapped in black plastic sheeting and cling film, a court has heard.
Alun Williams, 47, was unable to regulate his body temperature after being mummified and suffered dehydration which eventually led to a heart attack, a jury at Canterbury Crown Court heard.
The chef, who lived with his girlfriend, allegedly had an interest in bondage and mummification and would meet men online for sex.
Richard Bowler, 35, and David Connor, 23, from Canterbury, are charged with Mr Williams' manslaughter. They also face an alternative charge of manslaughter by gross negligence which they both deny.

Bowler, who has cerebral palsy which affects his co-ordination and movement, wept loudly as prosecutor Ian Hope opened the case and had to be asked by Judge Adele Williams to keep the noise down.
He said Bowler and Connor lived together in a flat in Dover, Kent, with Connor acting as Bowler's "informal carer".
Shortly after 6am on August 20 last year, Connor walked into the taxi rank where his mother worked and said "Mum, Richard's killed someone", the court was told. He mentioned bondage and a chemical which relaxes muscles in the anus.
Mr Hope said Bowler cut open the cling film and plastic sheeting to perform CPR and told the emergency services: "I thought he was just sleeping. He takes ketamine and that mongs him out."
Mr Hope said police found drugs including ketamine, cocaine, methamphetamine and amyl nitrate, otherwise known as poppers, in Mr Williams' rucksack.
Sex toys, masking tape, duct tape, black plastic sheeting and cling film were also found in the flat, the jury heard.
A post-mortem examination on Mr Williams' body confirmed that he had died suddenly following body wrapping while under the influence of ketamine and methamphetamine.
