My sub has been quite a whiner about the size of my dildo. Always, "Please stop mistress, it's too big!" I decide to punish him, and maybe he will learn to take my thick dildo. I begin by sitting on top of him, and paddling his big fat ass, while verbally humiliating him. Then, I sit on his face and grind my ass into it. Now, the real torment begins. I start teasing his cock, getting it nice and sensitive for the pain he's about to receive. Then, I bite his cock and balls hard, stretching them with my teeth. Now, he needs to be paddled on the cock and balls. I slap his cock and balls with my paddle mercilessly. Now, I tie up his balls nice and tight. I squeeze and torment his cock and balls with my hands. I take some clothes pins and clip them all over his balls. Mistress likes big balls, so i pull and tug hard on the clothespins to stretch his dangling fat balls even more. I end with a few more slaps to the balls with my paddle. I think he has learned his lesson, and his bottom will be more willing to take my big dildo
