Mistress Elena surveyed her dungeon with a satisfied smirk, the scent of leather and polished wood thick in the air. The new riding simulator stood gleaming under the low lights—a sleek, stationary robotic horse crafted from matte black steel and supple saddle leather. Its saddle featured a thick, ridged dildo positioned perfectly for her needs, and the spur aids were wired directly to its motors. One press of her heel would send it bucking or thrusting in precise dressage patterns. She ran a gloved hand along its flank, already feeling the familiar thrill of control mixed with anticipation.
The heavy door creaked open and her groom, Marcus, stepped inside carrying a toolkit. Tall and broad-shouldered, he paused at the sight of the machine. "Mistress, is this the new toy you ordered? Looks like it could throw even the most experienced rider." Elena turned, her riding crop tapping her boot. "It reacts to cues, Marcus. Unlike some stable hands who need constant instruction. Set the calibration for intermediate dressage—nothing too wild yet."
Marcus knelt to connect the power cables, his eyes flicking up to her tight breeches. "Intermediate? You usually start at advanced. Planning to break it in gently?" She laughed, sharp and low. "Gently is for amateurs. This one couples the dildo directly to the spurs. Every time I demand more impulsion, it delivers straight to my pussy. Now stop staring at my ass and tighten those bolts." He flushed but grinned. "Your commands are always so precise, Mistress. Makes a man wonder what it would take to earn a private demonstration."
"Wonder all you like," she replied, stepping closer so her crop brushed his shoulder. "Your cock stays in your pants tonight. This ride is for me alone. Though if you're good, I might describe how wet it makes me later." Marcus swallowed hard, his own arousal obvious in the tightening of his trousers. "You're cruel, Mistress. All this talk of thrusting dildos and I'm left with nothing but a hard-on and instructions." Elena's smile was wicked. "Exactly. Now finish up and leave. I want the dungeon empty when I mount."
Once Marcus departed, Elena stripped to her corset, boots, and spurs, the cool air raising goosebumps on her skin. She swung into the saddle, the dildo pressing thick and unyielding against her already slick folds. Gripping the reins, she gave a light squeeze with her calves. The machine hummed to life, rocking forward in a collected trot. The dildo nudged deeper, and she bit her lip at the first spark of pleasure.
"Good boy," she murmured to the machine, applying a subtle spur. It responded instantly, the dildo thrusting upward in a sharp, rhythmic pulse timed to the movement. Her pussy clenched around it, wet and dripping as the saddle rocked her hips. Sweat began to bead on her brow. She urged it into a canter, heels digging in, and the thrusts grew harder, deeper, filling her completely while the robotic ass-end lifted to simulate collection.
Panting now, Elena leaned forward, her breasts pressing against the pommel. "Faster," she commanded, spurring again. The dildo hammered into her, coupled perfectly to each aid. Her ass clenched with every jolt, the friction sending jolts of heat through her core. She was horny beyond measure, the machine's precise movements drawing moans from her throat. "That's it—give me that impulsion. Make me come on this mechanical cock."
The robotic horse shifted into piaffe, a high-stepping trot in place. Each spur press drove the dildo in short, powerful strokes that rubbed exactly where she needed. Her pussy grew wetter, dripping down the saddle as she rode with perfect posture, crop flicking the air. Sweat trickled between her breasts. She felt the orgasm building, tension coiling tight in her belly while her thighs burned from maintaining the dressage frame.
"Harder, damn you," she gasped, driving both spurs in. The machine surged, dildo pounding relentlessly. Elena threw her head back, panting and sweating, her body shaking. Her pussy spasmed around the thrusting length as she came hard, cum flooding the saddle in hot pulses. She rode through it, spurring again and again until the aftershocks left her trembling and dripping.
She dismounted on shaky legs, the machine powering down with a satisfied whir. Marcus would return soon for cleanup, but the real test of this simulator lay ahead. The door to the dungeon opened once more, and a familiar silhouette appeared in the frame.
