Katrin uses her slave as her seat while smoking a cigarette.
This time she uses a fragile part of her slave for sitting, this time she crushes his throat.
She settles down on his exposed larynx, wiggles a little bit for ensuring that the maximum of her weight is on the throat.
Smoking comfortable, while her seat is gasping for air with all her weight on the throat.
She uses his mouth as her ashtry, watching that he swallows it, the with an evilish grin, she sits back again with the full pressure of her weight.
Surviving as Katrin's ashtray is not easy and definitively painful.
