Today, I've decided to educate my sissy on the art of sucking big black cock. I push her down onto her knees, her eyes wide with anticipation and a hint of fear. I unzip my pants, revealing my massive, throbbing dick. She tentatively reaches out, her small hand barely able to wrap around my shaft. I guide her, teaching her how to stroke, how to lick, how to take me deep into her mouth. She chokes, tears streaming down her face, but I hold her head in place, making her take it all. I can see her trying to please me, trying to learn. I reward her efforts with a face full of my cum.
