Pretty sissy learns how to suck dick

It's time for my little sissy girl to learn how to suck dick. She is so scared and not willing, but I remind her that she wants to do it. I'm much taller and bigger than Kitten; towering over her, you can tell she feels powerless but to comply. She coyly says that she's excited to become a skilled dick sucker. So let's get her started with a nice pink dildo. I remind her that this isn't even close to the usual size of the cocks she is going to be made to suck. Taking the length of this down her slut hole should be so easy. I start by instructing her to tease the tip. Next, to worship the base ofthe cock and go up the shaft and twirl the tip in her mouth. With a little effort, I get her to do a satisfactory job fluffing up the cock. But she needs to perform the full treatment. When I hold the Sissy's chin in place and face fuck her with the dildo, she quickly gags and howls. I slap her. Taking dicks is her job from now on, so if she can't even swallow a small toy dick...
