She stripped naked the second the delivery guy left. The box sat in her living room like a dirty secret, heavy and humming with promise. Inside was the sex machine she had ordered after watching hours of videos where women got pounded senseless by relentless pistons. Her pussy was already wet just thinking about it.
She bolted the frame to the floor like the instructions said, attached the thick dildo attachment, and plugged it in. The motor whirred to life with a low growl that made her clit twitch. She climbed onto the padded bench, knees spread wide, and lined the fat silicone cock up with her dripping cunt. No lube needed. She was soaked.
The first thrust punched in deep. She gasped, fingers gripping the edges of the bench. The machine started slow, just like she set it, dragging that ridged shaft out and slamming it back in with mechanical precision. Every stroke hit the same spot inside her that made her eyes roll back. She reached down and flicked the speed knob higher.
"Fuck," she grunted. The machine sped up, fucking her in steady, brutal strokes. Her tits bounced with each impact. Wet sounds filled the room as her pussy slurped around the dildo, cream coating the shaft every time it pulled out. She pushed her ass back, greedy for more, and the machine delivered, pounding harder, deeper, faster.
Her first orgasm hit fast and nasty. Her thighs shook, pussy clenching around the invading cock as she squirted a little, soaking the bench. But the machine didn't stop. It kept thrusting through her spasms, dragging the orgasm out until she was whimpering. She tried to reach for the controls to slow it down, but her arm was shaking too hard. The dildo kept slamming into her overstimulated cunt, turning pleasure into something raw and overwhelming.
She came again, harder this time, a guttural moan tearing out of her throat. Juices ran down her thighs in thick rivulets. The machine was relentless, the motor whining as it fucked her through the aftershocks and straight into another peak. Her nipples were tight and aching. She pinched one hard, twisting it while the dildo battered her cervix.
"Too much," she panted, but she didn't turn it off. Instead she cranked the speed even higher. The machine responded with vicious, rapid thrusts that made her whole body jolt. Her pussy felt swollen and used, stretched wide around the thick shaft. Every plunge forced a wet squelch out of her, the sound filthy and constant.
She lost count after the fourth orgasm. Her legs gave out and she slumped forward, ass still presented, the machine continuing its merciless rhythm. Drool ran from her open mouth onto the bench. Her cunt was a mess, puffy lips gripping the dildo, clit throbbing with every brush of the machine's base. She could feel another climax building, this one deeper, meaner.
When it hit, she screamed. Her vision whited out as her pussy convulsed violently, gushing around the shaft. The machine kept pounding through it, turning her into a shaking, babbling wreck. Words spilled out of her, half-coherent pleas and curses. "Fuck me, fuck me, don't stop, you dirty fucking machine."
Eventually she managed to slap the emergency stop. The dildo withdrew with a wet pop, leaving her empty and gaping. She collapsed onto her side, breathing hard, cum and slick smeared across her thighs and the bench. Her pussy pulsed with aftershocks, tender and thoroughly used.
She lay there for a long time, legs trembling, a satisfied grin on her face. Tomorrow she would order the bigger attachment.
