Sorry but I have to say it. BDSM IS SAFE SANE AND CONSENSUAL.He's asking for something insane and unsafe. Sure there are people out there into temporary piercing, or fireplay and branding. Even branding is looked down upon.
Generally play should not to lead to injuries that can't be self treated or that require medical office or ER visits.
What if this guy is pulling and insurance scam, or some other scam that being beat beyond recognition is part of?? You could be considered an accessory to that crime. You say he claims to be into BS, yes BULL SHIT. The term may be BDSM, even then this is well outside the accepted play of anyone true to BDSM.
You'd also have to be pretty heartless to follow through with such extreme violence.
It's not okay to accept this kind of scene, as we in the BDSM/WIITWD world don't need some extreme psycho to add to the judgment we often hear already.
There have been recent scenes of claustrophobia and mummification resulting in death, so enough of the thoughtless and irresponsible play.
Just don't do it. Final thought he could set you up,with you having a signed release, that's as good as admitting pre-meditated assault.
Just not a good idea - and there are other clients where you can make money without hurting the client, your reputation adn that of us kinksters. Please think of how many people will be affeted. Not to metnion teh suffering and harm for this extreme 'client' He's also crazy, offering so little for the risk of you doing jail time.
This is a same, or some freak of fantasy this sad man has. Do not meet him, or talk to him anymore. Slowly back away.
Please say NO.
