A head chef at P&O Ferries died after two men wrapped him in cling film and plastic sheeting during a "kinky sex game", a court heard.
Alun Williams, 47, stopped breathing and suffered a heart attack after being "mummified" and voluntarily having a hood placed over his head, jurors were told.
Richard Bowler, 35, and David Connor, 23, from Canterbury, are charged with his manslaughter.
Canterbury Crown Court heard that despite having a girlfriend, Mr Williams had an interest in bondage and mummification and would meet men online for sex.
Prosecutor Ian Hope said the victim met Bowler, who has cerebral palsy, and Connor, who acts as his "informal carer", last year.
But shortly after 6am on August 20 the pair phoned an ambulance after realising Mr Williams was not breathing.
Mr Hope said Bowler cut open the cling film and plastic, which Mr Williams was wrapped in from head to toe, but was unable to revive him.
A post-mortem found he died suddenly following the body wrapping while under the influence of the drugs ketamine and methamphetamine, better known as crystal meth.
Other drugs including cocaine and amyl nitrate, otherwise known as poppers, were in Mr Williams' rucksack. Police also found sex toys, a gas mask and ties, the court heard.
Both Bowler and Connor deny manslaughter. The trial continues.
