Slavery: A series of erotic games (Book 03)
Shasta told us the steps she had to take before Bernice accepted he wasn't a boyfriend, he was a sex toy, just like a vibrator.
"I made Momma come to his bedroom. I still don't let him in mine. I chain his collar to the bed then tell him to lie down on his back on the bed and tie his arms and legs down so he can't move. I show Momma how I control him. I tell him to get hard, he gets an erection. I tell him to get soft, his dick go flaccid. I tell him to get erection again and then I mount his prick. I fuck him until I cum three times, then tell him he can cum. Then I make him lick his cum out of my cunt, lick my asshole. I get off him and order him to get hard again, then soft, then hard.
