I would want to be hanged in just my briefs or boxers, so the last thing I would be aware of was soiling my pants, and the audience would watch me piss and shit as I struggle, then ejaculate into my underwear at the end.
Or naked to the waist, he piss soakig my trousers during my strugges, then a bulge and brown stain at the back. As soon as I stop struggling, the hangman unzips me, feeling the cum in my underwear, then pulls my trousers down to expose my body in the sodden soiled and cum-in underpants with mess driblig down my thighs. Finaly he pulls the underwear down too, showing the audiece my erect cock above the dirtiedpubic hair and balls, swiging me round to show my soied rear, opening my buns to expose the open anus. Then i am left, exposed and naked except for my soiled clothes at half-mast round my legs, in the filth of death.
