Test Dummy: Chapter 9

"You ready, Rocky?!” Mark yelled from the other side of the tank. With a big smile, Rocky gave him a thumbs up.

It had been one week since Rocky had decided to join the Research and Development Team as a full-time product tester. Whenever Margrette returns from her leave of absence, Mark and Ned both agree that having two product testers would be a great benefit for the company, as now they could test their gear in “playdate scenarios” as Mark put it.

And that wasn’t even the best part. Rocky wasn’t just a full-time product tester. She was also on her way to becoming a full-time little. After Mark brought her back to his place, she was enamored with the massive nursery he had set up. He told Rocky that he used to have a girlfriend who was his little, but they had a falling out, so now he barely had a chance to use the nursery they built together.

That nursery was all it took to send Rocky’s mind into Little overload. She and her Daddy played together for the rest of the night, including some more mature activities.

Rocky was thrilled to find out that her new love for diapers wasn’t just because of the Super Absorber 3000’s aphrodisiac. Mark was a master at diaper masturbation. He had Rocky cumming in no time at all, giving her multiple orgasms over the course of the night and helping her fill her diaper with a variety of fluids.

The next day, Mark asked Rocky if she wanted to move in, and Rocky didn’t hesitate. She knew this was where she belonged.

The week that followed was a mess of paperwork and meetings with HR to deal with Rocky and Mark’s new “office romance,” on top of her new promotion to product tester. It was mentally exhausting for Rocky to field so many invasive questions about her personal and professional life, but Daddy told her she needed to be on her best behavior to make this work, so she didn’t complain.

Something that made this all easier was the warm reception she received from her co-workers. Apparently, word spread fast that Mark was carrying Rocky out of the building in nothing but a diaper.

Rocky was shy at first but quickly grew to love the way her friends started treating her. It got even better when she returned from lunch, finding her desk covered in presents and hand-me-down baby gear. Rocky had never experienced acceptance like this before and it made her happier than she’d ever been in her life.

But the main event was still to come. Ned halted testing on the Super Absorber 3000 until all of the equipment had been thoroughly looked over. He was a bit paranoid after the vibrator incident. So Rocky was forced to wait, until one week later, when Mark left Ned’s office with a big smile on his face, “Ready to get back to testing?”

I run over to Tina’s desk and grab her by the arm, dragging her towards the changing rooms. After everything that went down, we ended up becoming really close friends. Mark even brought her over to the house so they could play together (and so Rocky could have a front-row seat to Tina’s punishment, but that’s a story for another day.)

In the changing room, Tina made quick work of getting Rocky changed into a Super Absorber, spending extra time massaging her genitals as usual. Tina knew just how much Rocky loved to be teased, especially when she was poking at the butt plug that Mark had her wearing full-time, before tapping her up snuggly.

Rocky savored the scent of Roses that she had been hungering for all week. Her mind was instantly pushed to a state of euphoria. “Golly, what a baby I’ve become,” she thought to herself, giggling at her newly embraced immaturity.

Rocky was then brought into the testing chamber. She knew what was waiting for her. Mark had been building it up all week. Before she was the big tank that sat stationed in the center of the large room, and Rocky was finally ready to put it to use.

A team of people helped Rocky into a harness that wrapped around her waist and had two foot holds that she stepped into. It was designed specifically to keep the diaper from being restrained.

“Looks like we’re all good!” Mark pressed a button and Rocky was lifted into the air. The crane that the harness was connected to swung her overtop the tank and lowered her in until her feet were just able to brush the bottom. She looked around, noticing that the walls of the container she was in had at least a five-foot radius from her in all directions. She pondered, “the diaper couldn’t get that big, could it?”

Rocky stood proudly in the center of the tank, feeling everyone’s eyes on her. It was still something she was getting used to, but she was definitely starting to give in to her exhibitionist side. She craved the attention, relishing in the thrilling humiliation that it gave her.

Mark walked up to the tank and shouted, “You ready, Rocky?” With the thumbs-up confirmation from Rocky, Mark turned and addressed the room. “Okay, everyone! Today, we will be testing the Super Absorber 3000’s absorption and growth rates. To do this, we’re going to be flooding this chamber with 1000 gallons of water. Time to see how big this baby can get!”

The group of researchers cheered. Mark turned to his computer and typed in a few buttons. As he hit enter, the tank began to rattle. Soon, water began to rise up from the holes along the edge of the glass container.

Rocky was helpless in this situation. The harness acted like a baby bouncer of sorts, holding her in place and preventing her from trying to escape, not that she’d want to anyway.

The water was warm like a bath, sending waves of pleasure up Rocky’s legs as the level rose higher and higher. It soon was up and over the diaper, stopping halfway up her waist.

The team waited for the diaper to start inflating, but nothing happened.

“Goddamn, that lining really is 100% waterproof. Rocky, do you mind?” Said Mark with a twinge of impatience.

Rocky was a bit confused as to what Mark was asking for but realized quickly what he meant as he pulled on the waistband of his pants. She submerged her hands and grabbed onto the top of the diaper, prying it open.

Bubbles erupted from the padding as water began to enter rapidly. The nappy wasted no time drinking up as much liquid as it could as it started to swell at an expeditious pace.

In no time at all, the diaper had surpassed the 9000ml threshold that Rocky had hit previously and it showed no signs of stopping. She was happy that no one turned on the vibrator this time, or she would’ve lost her mind.

That didn’t stop Mark from getting some different vibrations going. He reached into his pocket, his fingers brushing past the various buttons that could bring Rocky to her knees. He pressed the “ON” switch of the remote, sending a signal to the butt plug inside of Rocky to get to work.

Rocky let out a gasp, her eyes darting over to Mark. “I must’ve been a really good girl for Daddy to reward me like this in front of everyone!” Rocky mused as she allowed herself to enjoy the frenzy of sensations.

The diaper continued to swell past the size of a beach ball and its weight was starting to cause strain on Rocky’s lower half. Its contents were so squishy and bulky that it kept her legs at least two feet apart, no matter how hard she tried to close them. She let go of her waistband, expecting the water to stop pouring in, only to realize that her diaper had swelled so big that it no longer needed her to hold it open.

Rocky had no way to stop the flow.

“M-Mark, it’s starting to g-get heavy,” She meekly cried out as her anus continued to buzz.

Mark took notice of Rocky’s predicament and started to lower the crane until the inflated diaper was resting on the floor of the tank, with Rocky seated on top of it. The water was now up to her chest.

Rocky was relieved to no longer be holding up all that weight. Now, she could sit back and enjoy herself, as the mass of wadding and fluff continued to expand with no signs of slowing down. She reached her hand inside her diaper, feeling how she could press into the squelchy material all the way up to her elbow, and yet the diaper showed no signs of tearing. It was as if whatever it was made of could stretch forever and ever.

The researchers swarmed around the tank, staring with gross excitement as the diaper started to swallow Rocky’s legs and waist. Each one of them wished internally that they could trade places with her.

Rocky, meanwhile, was loving the attention. “Who’s gonna change me out of this soggy diaper, boys?” she said, egging them on.

“I will!” Rocky’s head turned to see Tina, standing by the edge of the tank and holding a very familiar remote. She gave Rocky a menacing smile as she turned the Super Absorber’s vibrator on and tossed the remote into its watery grave.

Now Rocky was receiving double stimulation from both the butt plug and the egg in the diaper, with both cranked up to full speed. She turned to Mark for help, only to see him shaking hands with other colleagues and paying little attention to his little. She panted and moaned deeply, hoping someone would notice what Tina was up to.

The diaper met the sides of the tank and squished up against them. It only took a few seconds after that for the waistband of the diaper to plump itself over the waterline, halting its growth. But what didn’t stop were the thrilling sensations that Rocky was feeling.

Tina climbed up over the size of the tank and landed with a SPLAT! on top of the ridiculously swollen padding, with the intern sinking down into the pliable material. The sudden landing sent ripples all around Rocky, whose own lust was busy zapping her brain.

The unsteady surface made it hard for Tina to crawl over to her, but she managed to make it to the center, where she was now face-to-face with Rocky. “I hope you had fun the other night because it’s gonna be a while before I feel we’re even, Rocky baby,” said Tina before planting a kiss on Rocky’s forehead.

Rocky took a deep breath. She was never one to turn down a challenge, after all. “Bring it!” she stated defiantly, reflecting Tina’s own devious grin back at her.

“Am I interrupting something, or is someone being a naughty girl again?” The two girls abruptly turned their heads to Mark, who jumped aboard the massive nappy with them. “Did a little intern not learn her lesson?”

“O-Of course I did, sir!” Tina said, before scampering away, leaving Mark all alone with his padded princess.

Mark pushed his way to the middle of the bulging pamper, doing his best to repress the side of himself that just wanted to jump and roll around on the bulbous diaper.

Throughout all of this, Rocky was blissfully unaware of her surroundings beyond the euphoric feeling of buzzing and squelching. As the rest of her body began to grow numb and tingly, she began to drool, unable to hold her mouth open properly.

Reaching into his pocket, Mark pulled out a pink pacifier and plopped it into Rocky’s open mouth. She started sucking intensely as soon as the silicon tip met her lips.

Mark then started stroking her cheek and hair, causing his little giggle in between her ceaseless panting. “Now what do we say?” he said, staring into Rocky’s eyes knowingly.

Rocky looked back up at him, a proud smile growing on her face as she fought back against the torrent of arousal she was feeling, if only for a brief moment. “Ta-ta-tank you, Daddy,” she mumbled around her paci as best as she could before sinking back down beneath the waves of pleasure.

Mark took out the pacifier and planted a huge kiss. Rocky closed her eyes, savoring the taste of Daddy’s plush lips as she explosively creamed her well-ripened padding.

After almost a minute of making out, Mark finally pulled away, leaving Rocky’s tongue to hang limply out of her mouth. He took the opening to shove her binky back into place, occurring simultaneously with Rocky’s second big climax. Her eyes glazed over as she leaned over into Mark’s lap, mindlessly slobbering all over him as she cuddled him.

“That’s my baby girl.”

THE END.
