As part of My new sissy's training, she must learn to suck cock, but suck it well (otherwise I will make nothing whoring her out). Starting out she is trained by being bound and gagged with a huge penis gag so that she can have a better gag reflex. Now before I decide if I will keep her, I must test out her cock sucking skills. I have my large black cock and I hope she is ready for it - if not, she will learn to love it!
