I lay on the cold metal table, my heart pounding as Mistress circled me, her eyes gleaming with that cruel hunger. She wore tight leather that hugged her curves, her breasts straining against the fabric, nipples hard and visible. 'You're mine now, Håkan,' she growled, her voice low and commanding, making my cock twitch despite the fear. No limits, no mercy—that's what she'd promised, and my ass clenched in anticipation. She started with her hand, five thick fingers pressing against my tight hole. I felt each one, slick with lube, as she forced them in one by one. The first two slid in easily, stretching me wide, but the third and fourth burned, my rim protesting the invasion. 'Take it, you fucking slut,' she hissed, twisting her wrist to push deeper. By the time the fifth finger breached me, I was gasping, my dick leaking pre-cum onto my stomach. She didn't stop, shoving her entire hand inside, up to her elbow—that's thirty centimeters of her arm buried in my ass, filling me completely. The stretch was brutal, my insides clenching around her, every inch a mix of pain and filthy pleasure that made me moan like the desperate whore I was. She began fucking me with it, pulling out almost to her knuckles before slamming back in at a fast tempo—thirty thrusts a minute, each one pounding my insides without rhythm or pity. 'Feel that, Håkan? You're my sex slave now, and I'm going to wreck your tight little ass.' Her words echoed in the dim room, my body jolting with each thrust, the sound of wet slapping filling the air. I could smell the musk of sweat and lube, taste the salt on my lips from biting back screams. My cock throbbed, untouched, as she twisted her arm inside me, hitting spots that made stars explode behind my eyes. 'Not enough for you, is it?' she taunted, her free hand grabbing a thick dildo from the table beside us—twenty-five centimeters long, as thick as my wrist, with ridges that promised to tear me apart. She yanked her arm out with a wet pop, leaving my hole gaping and throbbing, then lined up the toy. 'Beg for it, bitch.' I whimpered, 'Please, Mistress, fuck my ass harder,' my voice breaking as she rammed it in. Twenty centimeters deep on the first thrust, stretching me even wider, the dildo pounding at a relentless pace—forty thrusts a minute, each one brutal and deep. I felt every ridge scraping my walls, the toy hitting my prostate with punishing force, making my whole body shake. She didn't let up, alternating angles to hit different spots, sometimes pulling out to the tip and slamming back in, twenty-five centimeters of hard plastic buried to the hilt. My ass was on fire, clenching around the invader, but I craved more, my mind a haze of need. 'You're going to take everything I give you,' she snarled, her breath hot against my ear as she leaned in, the dildo still fucking me raw. I could hear her panting, feel her other hand squeezing my balls, twisting just enough to hurt. The room spun with the intensity, my cock dripping, but she kept going, pushing me to the edge without release. It was endless, her dominance overwhelming, and I knew this was only the beginning.

She pulled the dildo out of my gaping ass with a slick, wet squelch, leaving me throbbing and empty, my hole stretched wide from the twenty-five centimeters of ridged plastic that had just pounded me raw. I gasped for air, my body slick with sweat, cock still leaking pre-cum onto the metal table beneath me. 'That's just the start, you worthless slut,' Mistress snarled, her voice dripping with sadistic glee as she reached for something else on the table. My heart raced, knowing whatever came next would push me further into the abyss of pain and pleasure she'd promised. From the shadows, she dragged out a massive python, its scaled body writhing in her grip—two hundred centimeters long, thick as my thigh, coiling menacingly. 'Time to see how deep your pathetic ass can take this,' she said, her eyes locked on mine as she lubed up the first fifty centimeters. I felt the cold, slimy scales press against my rim, and with one brutal shove, she forced it in, thrusting rapidly at a tempo of sixty thrusts per minute. The python's body slithered deeper, fifty centimeters buried inside me, stretching my walls to their limits, the undulating motion hitting every nerve in my rectum. I cried out, a mix of agony and ecstasy, as it coiled and twisted within, probing places no human arm could reach, my prostate battered relentlessly by the thick, scaly invader. But she wasn't done. 'You're going to beg for more, Håkan,' she taunted, pulling the python back slightly before ramming it in again, each thrust making my body jerk violently. Next, she positioned a horse cock dildo—sixty centimeters thick, a monstrous girth that made my eyes water just looking at it. 'This one's going to split you open,' she laughed, lining it up and slamming it into my already abused hole. Forty thrusts per minute, each one driving it deeper, the sheer thickness forcing my ass to accommodate its impossible size. I felt every centimeter, the dildo pounding at least forty centimeters in on each stroke, my insides clenching around it like a vise, the pressure on my prostate making my vision blur. 'Take it, you fucking whore,' she commanded, her hand gripping the base as she fucked me harder, the wet sounds of my ass echoing in the room. As if that wasn't enough, she introduced a giant dog, its massive form straining on a leash she held. The beast's cock was enormous, thirty centimeters deep on the first thrust, its rhythmic pounding brutal and unyielding. 'Feel that animal claiming your ass,' she hissed, guiding it forward. The dog mounted me instinctively, its shaft plunging in and out at a steady tempo of fifty thrusts per minute, each one hitting thirty centimeters deep, stretching me wider than the python had. I moaned incoherently, the fur against my skin, the raw animal heat overwhelming as it knotted inside, locking in place and pulsing, my ass forced to milk it dry. Then came the demon, a nightmarish entity she summoned with a few muttered words—its appendage a solid one-hundred-centimeter object, ridged and demonic, glowing with an otherworldly heat. 'No mercy for you,' she growled, as the demon rammed it in without warning, driving it deep in a frenzy of thrusts, eighty centimeters on the first go, then pulling back only to slam in harder. The tempo was relentless, seventy thrusts per minute, each one tearing into my core, the heat searing my insides as it invaded without pause. I screamed, my body convulsing, but she just laughed, her dominance absolute. Finally, the robot dildo whirred to life—twenty-five centimeters wide, a mechanical beast with spinning ridges and unstopping power. 'This will drill you into oblivion,' she said, activating it and thrusting it into my ruined hole. It pounded at a high-speed tempo of eighty thrusts per minute, forcing itself twenty centimeters deep with each mechanical stroke, the vibrations shaking my entire body. My ass was on fire, every sensation blending into a haze of endless penetration, but I knew this was just another layer of her twisted experiment, leaving me craving the next violation.
