I'm not sure if the tease is allowed. The issue isn't the castration per say (definitely out there but, well, you do you), but rather the gore and even more so the implied death. That sort of stuff has made the international news before, castration leading to death, and people have been convicted of manslaughter. There is no government in the world that wouldn't find it a capital offense, the content of the tease. So...yeah...you can't defend it sorry
Also story is not convincing... I did not play the tease (and did not vote) and I did not even know about the end but I clicked the link and saw that on introductory page "you were sent there by your wife" - without any reason. Most wives I know (plus all the girls that I have ever been with) would never do that to their husband. They love cock, and they worship it. Many can never get comparable experience any other way like orgasming from real cock. Ye eating them out is nice and all but that orgasm leaves them wanting for more.
Maybe if you permanently suffer from premature ejaculation and she can never get off... but in that case she could simply leave you and find another man.
