I would like to preface this by saying you shouldn’t do this. You should not kill you self. I am not condoning this. But, if you really wanted to die and have it look like an accident, which I am NOT SAYING YOU SHOULD DO, go to google, go to pornhub, find a video, put a belt around your throat to where it starts to suffocate you, put lube on your hands, and take your dick out. It’ll look like someone who is into autoerotic asphyxiation had a freak accident and ended up killing themselves. It’s not an intentional suicide, and you can get your friend to back you up by saying it’s a fetish you have been doing for a while but this time you got unlucky. I would advise you not do this though. If you tell me a bit about your situation I can probably help you find some easy ways to make a lot of money, as long as you are willing to throw away your moral compass and empathy.
