Repitition - Sissy Training

Like so many other things he's learned in his life, your Sissy needs to learn to be an expert cocksucker!!!
The only way is to have him suck one cock after another....always under your close supervision....for as long as it takes until he's mastered the art!!!!
But don't let him slack off....line those cocks up again once every couple of days....keep doing it until he is ready to drop to his knees and open his mouth at a moments notice!!!!
