Entrenando a un esclavo para convertirse en una silla

I must sound like a broken record by now, but I can't deal with having such a weak slave! I'm training him to become a full time seat. My plan is to dehumanize him to the point where he is a sturdy, silent and reliable chair so I can use him as my primary piece of furniture. I might sell off all my other seats and use him exclusively! It's a nice dream, but I'm a long ways off from that goal, because my slave does not have the stamina to hold my weight. I'm a big girl and I need a chair that can handle me for any amount of hours at a time. My slave trembles after several minutes and I have to kick him to try again, just for him to cave in only a little bit later. I'm disgusted by this incredible display of flaky weakness. I move over to the other seat and bury his face between my thighs to receive his punishment. I whip him up badly, leaving nice pink lashes all over his back until he is tears into my pussy.
