My soul fell forwards through time towards Maru's bedroom. She was kneeling over a mechanical contraption, the likes of which I had never seen. The light of her posable floor lamp shone searingly bright on her gloved hands as she worked at tightening down the bolts near the base of her creation. I landed on top of the lamp and watched, transfixed by the skillful movement of her fingers as she ran them over her invention checking for parts that are loose or bent. She sat back, slapped her hands together, and smiled. I reached into her head and sank into her stream of consciousness. A wave of pride and satisfaction rolled over me.

Perfect~! With these slight modifications my machine is flawless. Now I just need to test it.

She made a quick lap around her house, dipping her head into Robin and Demetrius's room as she passed. She didn't bother checking the basement.

Parents aren't home, and it shouldn't matter if Sebastian is or not. He won't be able to hear anything from the basement.

She shut the door to her room behind her and locked it, locked the door to their side yard, and pulled her curtains closed. Then she slipped off her clothes and hung her shirt and overalls over the back of her desk chair, dropping the rest to the ground. She slid the machine into a slotted receiver clamped onto the end of her bed and grinned, her hands on her hips.

Now…the new addition.

She opened her desk drawer and grabbed the black fabric tool roll from within. She crawled on her bed and unfurled the roll across it, exposing a dozen pockets holding colorful rods. She ran her fingers along the edge of the roll, pausing at the last rod. It was thick, green, and curved subtly left. Maru bit her lip as she slipped it out of its pocket and turned it in her hands, inspecting its length. She screwed the dildo onto the machine and snatched a remote off its side. She held down a button on the remote and the dildo extended on a mechanical arm, which she guided down to her mattress. She measured the space between the mattress and the machine's arm with her hand and released the button when she was satisfied with its height. The arm locked into place.

Time for testing~!

Maru reached back into the roll and pulled a small bottle of water-based lubricant free. She squirted some onto her finger and coated the dildo with the slick substance, wiping the excess off on her bedspread. When the rod was fully coated she laid back on her bed and scooted towards the machine, her legs dangling over the end of the footboard. She pressed another button on the machine and it hummed to life. The arm began slowly pushing forwards, thrusting into her without pretense or hesitation. She gasped and grabbed the blanket beneath her, her hands desperately trying to aid her knees in the momentous task of holding herself in place as the machine's force pushed her away from it.

That curve was a good addition, I can't believe something so simple could feel so…

"Ahh~!"

She shivered, one hand pawing around the blanket to find the remote. She slapped her hand over it as she found it, biting her lip again in anticipation as she rolled a stiff wheel on the side of the remote to a higher setting. She dropped the remote onto her chest and returned her fist to the blanket. The machine purred and began to move faster. Maru moaned as the machine thrust into her, sweating with the effort of holding her body in place as the machine forced it back and away. The slickness between her legs grew as she wriggled herself down, coating the rod and herself in her juices. She began to rock her hips subtly up and down, matching her grinding motion to the rhythm of its ceaseless thrusting. The dildo's tip slid past her g-spot with every thrust, and heat began to build inside of her. She swatted at the unrolled bundle of rods, snatching it closer to herself. Her body writhed under the unstoppable onslaught of the machine as her shaking hands loosed a short, thick purple rod with a hole in its end.

I bet it would feel amazing with this, too.

She positioned the hole in the end of the purple suction vibrator over her clit and held down a button at its base. The vibrator began to shake, whirring with increasing intensity as she clicked it up to its highest setting. She gasped, her eyes shooting wide open as the machines worked her over. Her body twitched as the intensity of her feelings built, then broke. Her moan tore out of her throat, a loud wail that wavered as the fucking machine shook her back and forth. She spasmed around the green rod, her muscles tightening as the burning need for release spread through her, scorching her all the way to her fingertips. Her legs clenched and kicked forwards, and the machine pushed her up the mattress and out of its reach.

Damn it! So close.

She groaned in frustration and dropped the vibrator beside her, trading it out for the machine's remote. She pressed a button on her remote and sighed, watching the machine roll itself to a stop.

There's one more test I'd love to try with Mr. Green here, anyway…

Maru glanced back to the door. Her cheeks flushed red as she mulled the idea over.

The door is still locked, and the house is still quiet. There's no better time…

She readjusted the height of the machine's arm and locked it into place, then brought herself up in a table top position on her bed and backed towards it. She placed its tip against her ass, dropped her chest to the mattress, and pushed a button on the remote again. The machine began to move. It pushed into her as easily and with as little remorse as only a machine could, mechanical arms pushing the green dildo as deeply as it could reach. Maru let out a loud moan of pleasure as it drove into her, her body rocking forwards and back as it moved. She lined the vibrator up under herself, holding it snugly in place with her hand as she desperately steadied her body against the mattress with the other. She turned it on and started grinding it against herself as the machine tore into her. The machines performed their roles flawlessly, metal and silicone working in harmony to give Maru the harshest anal fuck of her life, just as she had designed them to do. Her body, however, began to shake itself apart.

Fuck, so quickly? I can't come yet, I haven't even tried the heat settings, ah~!

She shouted as she came, her voice raw and rough as her pleasure ripped itself out of her lungs. Her body collapsed. She lay beneath the arm of the machine, gasping to catch her breath as it thrust in the air above her. She turned off the vibrator and stilled the machine's arm, slipping its remote back into its slot.

That'll need to be cleaned shortly.

She let her hand fall on her chest, watching as her breath caused it to raise and fall in gently slowing waves.

And a few modifications could be added…perhaps a self-lubricating stream…or…hmm…

Her eyes drifted closed, content.
