I was ooking for a specific story about a horse family I think. They were short on money and made a Deal with a show to snuff their eldest son, Who was initially unaware that his family was trying to kill him. Then when he learns of It and he willing lets himself be snuffed for the money. Then one of his siblings also kills their father for some reason I don't remember.
I remember that one of the brothers try to decapitate the main charcater by using a sharp string, his mother try to poison his food, his father try to plant a "gun" into his chair (but he tried to use his dildo on the chair and the dildo absorbed the bullet).

I also remembered that when he confronted his family he put his dick on the table and started to masturbate and he said something among the lines of "You guys are going to kill me and this is the weird part?". There was also eletrocution. I think it was the sister who tried to eletrocute her brother and failed on purpose to make him overhear her talking to her friends about the whole plot to kill her brother for money.
Does anyone have this story or any other story by this author?
