A SUBMISSIVE fetishist found dead after a kinky sex session with a dominant male died on their 'unlucky 13th meeting'' a court heard today.

Kim Dohoon, 36, was in a kinky hook-up relationship with Kevin Adams, 53, who is accused of killing him through gross negligence.

Kim died wearing a gas mask and with his hands and ankles tied and a ligature around his neck and had taken a cocktail of drugs.

Adams is accused of causing his death after falling asleep, leaving his sex partner in a "vulnerable" position, and denies the manslaughter charge.

But a court was told it was possible Kim could have released himself from the ties, on the "unlucky 13th" time the pair met up at Adams' home in Exmouth Street, Swindon.

The pair met on a dating site and quickly established that they met each other's needs - as dominant and submissive sexual partners.

But after hooking up for fun on 12 occasions events took a tragic turn at last year.

Defending Adams, Pavlos Panayi QC, said the pair had a "strong affection" for each other.

He said it could easily have been his client who died and Kim who appeared before the court due to the "potentially fatal" mix of drugs.

Mr Panayi said: "Kevin and Kim met to have fun - they met before, they had done the same drugs, and had the same kind of fun.

"No-one was hurt before and no-one expected anyone to get hurt that night. This was the awful, unlucky, 13th meeting."

He suggested Adams passed out due to the drugs and the physical exertion rather than making a conscious decision to leave Kim trussed up and lying on the floor.

Mr Panayi asked the jury to consider whether the restraints "had been designed for easy and quick release" and if Kim could have released himself.

He demonstrated to the jury how it could be possible to pull the velcro away after loosening a clip using his thumb.

Mr Panayi said: "Did Kevin Adams believe he was the only one that could have released Kim from the ties?

"Did he have any inkling that the other man was in any kind of danger?

"You will hear evidence from toxicologists about the individual effects of the drugs the men took, and perhaps more importantly of the potentially fatal effect of the combination of the drugs.

"These drugs are taken every day around the country in sexual contexts and non-sexual, for fun.

"If Kevin Adams had died from the drugs he had taken, not Kim, Kim could have untied himself. He did not need someone else to do it for him.

"It may be pure chance that the perfect storm of circumstances resulted in the death of one of the men and not the other."

Mr Panayi added: "If the drugs alone might have killed Kim, even if he was tied up and wearing a mask, then there is no case to answer.

"This is a set of events that happened in a safe environment, in a bedroom and was supposed to be enjoyed by two men.

"In the end what we are asking is 'was what happened a crime or a terrible, awful, tragic accident?'"

Adams had texted different men about his sexual fantasies which revolved around "breathing control," including reducing air flow through a gas mask before opening the hose to release a large amount of poppers, it was said.

Prosecutor Adam Feest QC said: "There are many ways in which being somebody's wellbeing can be looked after.

"Releasing the binds, making sure the gas mask is taken off, simply asking 'are you OK?'.

"There are steps that could have been taken that were potentially life-saving but haven't been done."

He added: "The defendant must have been aware of the risks involved in tying someone up and applying the gas mask.

"The vulnerability of such a submissive party must have been known and obvious."

Kim had taken date-rape drug GHB and a "rather high level" of M-Kat before his death, which a pathologist said could cause irregularities in heart rhythm.

Meth-amphetamine and viagra were also detected in Kim's blood and a cause of death was given as partial airway obstruction and mixed drugs, methedrone and GHB.

The pathologist said: "The degree of airway obstruction appears to be relatively mild.

"There were no features to suggest forceful neck compression."

He added: "I think any medically trained person walking in and finding someone bound with a gas mask on would say 'that looks dangerous, that could go wrong very easily'.'"
