As I, Sissy Sarah Tidmarsh, knelt before the towering figure of Master Maxwell, my heart raced with anticipation and fear. A successful English businessman, he had taken a liking to me, a lowly sissy maid, and decided to train me in the ways of submission and pleasure. "Sissy Sarah," he growled, his deep voice sending shivers down my spine. "You have been a bad girl. You have not been focusing on your chores, and your mind has been wandering." I hung my head in shame, knowing that I had been daydreaming about a certain large, black cock that I had seen in a magazine. I had been fantasising about what it would be like to be filled by such a magnificent specimen. "I'm sorry, Master Maxwell," I whispered, my voice trembling. "I will try to do better." He chuckled darkly, his eyes gleaming with amusement. "I know you will, Sissy Sarah. But for now, you must be punished." He reached down and grabbed my chin, forcing me to look up at him. "You will enjoy this punishment, my little sissy. You will cum harder than you ever have before." He then produced a chastity cage, locking it around my delicate cock and balls. The cold metal sent a chill through my body, and I knew that I would not be able to cum unless he allowed it. He then led me over to a large, leather-covered spanking bench, bending me over it. He secured my wrists and ankles with soft, velvet ropes, leaving me helpless and exposed. He then ran his hands over my ass, squeezing and kneading the flesh. I couldn't help but moan as he touched me, my body betraying my desire. "You like that, don't you, Sissy Sarah?" he asked, his voice full of amusement. "You like it when I touch your ass." "Yes, Master Maxwell," I whimpered, my face flushed with shame. "I do." He then produced a large, black dildo, the same one that I had been fantasising about. He ran it over my ass, teasing me with the promise of pleasure. "You want this, don't you, Sissy Sarah?" he asked, his voice full of dark amusement. "You want me to fill your ass with this big, black cock." "Yes, Master Maxwell," I moaned, my body begging for release. "Please, fuck my ass with your big, black cock." He then slid the dildo into my ass, filling me completely. I cried out in pleasure as he began to fuck me, the sensation of the thick, black cock sliding in and out of my ass was indescribable. He then reached around and began to play with my clit, his fingers expertly teasing and rubbing the sensitive nub. I moaned and writhed, my body on the brink of orgasm. "Cum for me, Sissy Sarah," he commanded, his voice full of power. "Cum for your Master." I then exploded in an anal orgasm, my body shaking and convulsing as wave after wave of pleasure washed over me. I cried out, my voice echoing through the room as I came harder than I ever had before. He then pulled out the dildo and led me over to a large, plush chair. He sat down and pulled me onto his lap, his still hard cock pressing against my ass. "Suck my cock, Sissy Sarah," he commanded, his voice full of authority. "Drink my cum." I eagerly took his cock into my mouth, sucking and licking the shaft. I moaned as I tasted his precum, my body begging for more. He then grabbed my head and began to fuck my mouth, his cock sliding in and out of my throat. I gagged and choked, my body fighting for breath. "Swallow my cum, Sissy Sarah," he commanded, his voice full of power. "Drink every drop." I then felt his cock swell and twitch, his hot cum filling my mouth. I moaned, swallowing every drop of his seed. He then pulled out of my mouth and led me back to the spanking bench, bending me over it once again. He then began to spank my ass, his hard hands leaving red marks on my flesh. I cried out, my body a mix of pain and pleasure. "You will remember this punishment, Sissy Sarah," he said, his voice full of authority. "You will remember who is in charge." "Yes, Master Maxwell," I whimpered, my body trembling with a mix of fear and desire. "I will remember." He then unlatched the chastity cage, allowing my cock to spring free. He then began to stroke it, his hand expertly teasing and rubbing the sensitive flesh. "Cum for me, Sissy Sarah," he commanded, his voice full of power. "Cum for your Master." I then exploded, my cum shooting out and landing on the floor. I moaned, my body shaking and convulsing as wave after wave of pleasure washed over me. He then led me to a large, four-poster bed, laying me down on the soft, silken sheets. He then climbed on top of me, his hard cock pressing against my ass. "I'm going to fuck you now, Sissy Sarah," he said, his voice full of authority. "I'm going to fill your ass with my cum." I moaned, my body begging for more. He then slid his cock into my ass, filling me completely. I cried out in pleasure as he began to fuck me, his hard cock sliding in and out of my ass. He then reached down and began to play with my clit, his fingers expertly teasing and rubbing the sensitive nub. I moaned and writhed, my body on the brink of orgasm. "Cum for me, Sissy Sarah," he commanded, his voice full of power. "Cum for your Master." I then exploded in another anal orgasm, my body shaking and convulsing as wave after wave of pleasure washed over me. I cried out, my voice echoing through the room as I came harder than I ever had before. He then pulled out of my ass and climbed off of me, laying down next to me on the bed. He then pulled me into his arms, holding me close. "You did well, Sissy Sarah," he whispered, his voice full of warmth. "You pleased your Master." I snuggled closer to him, my body exhausted but satisfied. I had never experienced such pleasure and pain, such mind-blowing orgasms. I knew that I would never forget this night, the night that I had been punished and pleasured by my Master, the powerful and dominating Master Maxwell.
