One of the hardest things for any sissy to control is his love for BBC. They long for that nice, long, thick, dark monster. I am the best BBC sissy trainer. Since I also love big black cock, I am happy to use that BBC for training. I take my sissies and dress them in their pretty little panties, painted nails and toes, made up faces, sweet little bows and some nice ruffled socks or thigh high hose. I have them sit by the bed and watch Mistress Francis play with a big black cock. They must kneel and watch my every move, never drifting from eye contact. If I see their little clitty getting hard I will remind them that they are not to cum without my permission. I make them watch me open my mouth wide and take that giant monster of a cock deep in my throat. Fucking my throat hard until it fills my mouth full of cum and it drips from my lips. Although that sight will drive them wild, they still may not cum in their panties. Then I spread my legs wide and take that gorgeous cock deep in my pussy, his balls pounding against my ass with every stroke. As the BBC know exactly how to fill up a woman completely I will cum in no time. I will then check my little sissies’ panties for any cum. If they have any little cummie in their panties they will get a clitty spanking. However, if they refrain, I will let them lick that BBC clean and then lick all that BBC cum out of my cunt. They know the rules so they will work so hard on not cumming without asking so they can feast on that BBC.
