opened up at the front, a big cylindrical machine was being raised up from the hidden compartment. It had a big, circular hole in front of it, and it slowly positioned itself, in a 45 degree angle, in front of Nami's stiffness.
Robin held Nami's sensitive member in place and pushed the cylindrical machine towards it. The machine quickly engulfed Nami's cock, stopping just short of her groin. It had been crafted after very specific measurements, so it fit perfectly around Nami. The mouth of the machine began closing around the base of her shaft. With a *click*, the cylinder was locked in place.
"Let's see what this thing can do…" Robin said.
She pressed another button on the controller, and almost instantly after she had done so, Nami jumped in surprise. The interior of the cylinder coiled around the dick it had just swallowed, and a myriad of wet, rubbery tendrils began rotating around it. Nami moaned as the machine began to work her quivering meat. Robin pressed another button. This time, a large ring inside the cylinder began stroking Nami up and down her shaft and released a hot, sticky substance all over her trapped cock.
"Ooooooooooooooh my god!" Nami moaned.
The liquid inside the machine appeared to be some sort of lubricant, but there was something else to it. It was hot, unbelievably hot! The cylinder stroked and massaged the lube all over the pulsating member. It felt so fucking good! All those tendrils sliding and flickering all over the place, the intense sucking and the stroking were too strong, in a very good way. Nami felt herself reaching her climax, at a rapid speed.
"I'm g-going… to… cum!" Nami's balls tensed and push up towards her body, ready to fire.
"…" Robin grinned.
"!" Nami gritted her teeth as her eyes shot open. "I CAN'T CUM!"
The mouth of the machine sat too tightly around her shaft. She tried to pump her cum out, but it was impossible. Her boiling semen was still trapped inside of her frustrated balls! She moaned and groaned as the machine increased in speed, almost as it desperately tried to milk her balls empty. But she only edged and edged, with no end in sight. It was pure, blissful torture!
"LET ME CUM!" Nami pleaded. "IT'S TOO MUCH!"
"Yes, beg for mercy!" Robin moaned as she jerked herself off. "Let me hear those delicious cries of yours!"
"CUUUUUM!" Nami groaned; drool running down from the side of her mouth.
"Fuck… I'm going to cum! Watch me cum, Nami! Watch me ejaculate all over you so you can see how good it feels!" Robin furiously stroked her cock, aiming it towards the edging navigator. "Catch my sperm!"
And as Nami kept edging in the chair, Robin moaned as string after string of hot, sticky cum shot through the air. Nami whimpered as she saw Robin ejaculate. She wanted to feel it too, she wanted to cum so badly. The semen landed all over Nami and the machine, but Robin just kept cumming, coating Nami's face and tits with hot jizz. Over and over, Robin kept releasing her cum, until she finally fell over and landed on her bed.
Her cock twitched and jumped from the small orgasms that still shot through her body. She involuntarily humped the air as the waves of pleasure washed over her, all while listening to the sound of Nami edging and moaning in the background. Robin crossed her arms and closed her eyes. Just to the side of her, up from her sheets, appeared two naked clones of herself. The two clones crawled seductively towards the real Robin, letting their tongues hang lewdly from their mouths.
The two clones finally reached her and began lapping all over Robin's sensitive cock. They positioned themselves on either side of her body, licking her from two sides. Robin clenched the sheets with her hands as pleasure surged through her throbbing member. She pushed her hips up; making sure Nami had a perfect view of the action. The clones looked at Nami, their eyes full of lust as they lewdly drooled and licked all over Robin.
Nami moaned, tears running down from her eyes as she was being forced to edge over and over again, within the confines of the tireless machine. She felt her mind starting to slip into madness as the cylinder began to vibrate around her. The only thing Nami could do was to curl her toes and dig her nails into the soft fabric of the armrests. Surely it couldn't get worse?
Suddenly, the clones began to suck and stroke Robin's large cock, almost fighting over who could take more of it down its throat. As if that wasn't bad enough, Nami's balls started to expand, increasing rather drastically in size. "R-R…Roo-oob…i-in!" was all that Nami managed to say, as Robin used her powers to enlarge Nami's cum sack. Only until her testicles were the size of tennis balls, did the growth finally halt.
"I'm cumming again, Nami! Look at me ejaculate!" Robin moaned.
The clones kept stroking and licking all over Robin as she unloaded her second volley of cum. Globs of cum shot out of her cock and fell down, plastering her face. Even after the final string of semen had been released, her clones refused to stop what they were doing. They were like the manifestation of her pure, insatiable lust and desire. Robin tried to make them go away, but she had completely lost herself in the moment and was no longer able to stop them.
After being forced to cum six times, the clones finally disappeared as Robin's strength was all gone. Her entire body was covered in her own spunk, reminding her of what had just happened. Her breath was ragged and she was beyond tired. She could still hear Nami's cries in the background. With the last ounce of strength she had left, Robin reached for the controller and pressed a button. The mouth of the cylindrical machine loosened up and finally allowed Nami to achieve what she's been wanting over a week for.
"Oooooooooooooh!" Nami wailed as the sensation in her balls came crashing down upon her. Her eyes rolled backwards and her jaw dropped completely, letting her tongue dangle from her mouth. With a final, heavy gasp, her balls began pumping. Nami came, and she came hard.
Nami's cock exploded with a tremendous force. The cylinder tried to suck all of her thick, sticky cum down its tube, and into the collector it was connected to, but it was too much. Nami's ejaculate gushed out of the mouth of the machine, spilling all over her lap, and down on the floor. The experience was so intense that even Robin could feel the force of Nami's orgasm. Her eyes were glued at the incredible sight in front of her. Her own cock began to twitch and tremble, and by the time Nami had released her second load, Robin was already having her seventh orgasm.
Robin moaned as the orgasm rolled over her. It was much milder than her previous ones, but this one had a much more straining effect on her mind. Quickly after her orgasm had died down, she began to feel incredibly drowsy. And soon thereafter, Robin had fallen asleep, still covered from head to toe, in her own semen. Unfortunately, the machine was still active, and Nami was still cumming her brains out.
The sizes of her loads were finally at the point where the machine could swallow everything that Nami poured out of her cock. Unaware of how the machine operated, Nami was forced to cum until either Robin woke up, until the collection tank was full, or until nine hours later when the machine runs out of power. Her mind was completely void of thoughts at this point, she wasn't even aware of her surroundings. All she could do was to feel was the multitude of earthshattering orgasms that was forced upon her and let her mind scream for mercy.
Darkness finally began settling over the Sunny and even though several hours had passed, Nami was still stuck in the chair, filling the tank with her semen. Luckily for both of them, they would have no one interrupting them until the next day. Franky had been so kind to tell the others not to disturb them until they came out themselves. So Nami's got plenty of time to enjoy the constant torture of the cock-milking machine.
