Shit Pressed Into His Mouth During Facesitting

My slave is lying on the lounge chair in the studio. I sit right on his face and order him to massage my plump ass intensely. Just the sight of my ass drives him wild with lust, and he can hardly wait to breathe in my scent deeply.
While I am sitting on his face, I stroke his erect cock to deliberately train him to take my shit. It takes hardly any persuasion. Completely desperate, he searches for my shit, whereupon I let him lick my asshole intensely.
I start to push and load one fresh turd after another directly into his open mouth. At first, he swallows my shit obediently and greedily. When the amount finally reaches his limit, I show him mercy. While he deeply inhales the intense smell of my shit right in front of his nose, he is allowed to relieve himself without restraint and cum all over his rock-hard cock.
