The Product Tester - Chapter 12

Fabulous illustrations by @HofBondage. 

We're coming up on the home stretch here. There's only one chapter left for this story! 

Mary squirmed as Rebecca moved her changing table back, rotating it from an upright position into a laid-back one.  “This isn’t fair.” 

The caretaker smirked down at her. “Who suggested that anything about your stay here would be fair, little one? Bottoms up!” 

There was a moment of confusion before Mary realized that she was giving instructions, and lifted her butt off the changing table. Rebecca slid an all-too-familiar disposable diaper beneath her, and turned to pick up the tube of powder from the table so she could apply a thin, even coat.

“I didn’t agree to this!” Mary pleaded. After the hour-long teasing session, she was incredibly frustrated, and the chastity belt locked around her served as an almost painful reminder that she wasn’t going to be getting any sort of satisfaction for a long time. “Please, don’t-” 

She spread her legs a little as Rebecca pulled the diaper up, taping it snugly. Frowning, Mary lifted her head. This diaper felt just a little different than the ones she was used to. Peering at it, she saw that the backing was different. Not plastic, but something more flimsy, and… it looks like it’s perforated? 

Reaching back, Rebecca picked up a second, slightly larger, diaper from the table. “Bottoms up!” 

“That’s…” Mary started to say. Squirming in discomfort. “What’s that for?” 

“So you don’t leak, of course,” Rebecca explained. “Now, lift that tushie, unless you’d like a spanking when we’re done here.” 

The threat was obviously an idle one, and Mary couldn’t help but point it out. “Like I’d be able to feel it beneath all that diaper.” 

“Your thighs won’t be beneath anything,” Rebecca pointed out. 

Mary lifted her butt. 

Rebecca slid the second diaper beneath her, folded it in place, and taped it down. Then, humming a little happy tune, she reached for another one. 

“You’re kidding,” Mary complained. 

“I don’t kid when it comes to keeping babies nice and dry,” Rebecca said, tapping a finger on her lip. “Well, not dry, but at least leak-free. Up!” 

Mary obeyed, as the third diaper was taped around her. It, at least, had the familiar plastic backing she was used to, but the bulk of the three layers was simply enormous. 

And, next came the cover. The plasticy material barely stretched to cover it, but it still locked securely into place over her many diapers. 

At long last, Rebecca moved to uncuff her. “Now, little Mary, we’re going to go have lunch here in a moment, and then I’ll put you down for a nap. Does that sound okay?” 

I guess? As soon as she was free from the restraints, Mary sat up and moved to hop off the changing table. There were still mittens on her hands and booties on her feet, but she didn’t think that would be a problem until she dropped to the floor.

Between the rigid, curved soled of the booties, and the incredible bulk between her legs, she couldn’t stand. After a moment of wobbling, she toppled forwards, and Rebecca had to catch her before she could faceplant. 

“Let’s go down a little more gently, shall we?” Lowering Mary to the floor, she helped her onto her hands and knees, in a less precarious position than trying to stand. 

Of course I have to crawl. It was humiliating, but Mary couldn’t really argue the point. If she tried to walk, she’d probably spend more time falling over than moving forward. 

When Rebecca opened the door and led her out into the hall, Mary had no real choice except to follow. Her “babysitter” went three doors down, stopped to unlock the door, and led her into the next room. 

It was… a nursery. 

There was no confusing it for anything else. A crib, a changing table, a high chair, and a small play area in the corner were painted in matching baby blues and pastels. It wasn’t huge, but it had everything you would need to care for a baby… except that it was all sized for an adult Mary’s size, and looking in the playpen, she spotted a few ‘toys’ that were conspicuously adult-oriented. 

For now, Rebecca lifted the tray on the high chair and bent to give Mary a hand. 

Mary wanted to ask questions. She was even opening her mouth to ask them, but then it occurred to her that - if she was really a test subject for whatever was being tested here - she would know what was going on. Asking too many silly questions might get her caught. 

So, she diverted to a much more obvious question as she clambered into the high chair and turned to sit down. “What’s for lunch?”  

Latching down the tray, Rebecca took a bib from her apron pocket. Rather than tying it around Mary’s neck, though, it just clipped straight onto her collar, hanging over her naked chest. “You get to pick, little one!” 

Oh, good-

Bending to open a drawer beneath the changing table, she came out with two oversized jars and a plastic spoon. “Peas or strained carrots?” 

Mary blinked. The whole ‘baby’ aesthetic was one thing, but she wasn’t actually expected to eat that crap, was she? 

Apparently, she was, because Rebecca was holding up both jars expectantly. Mary frowned at them. “Aren’t there any other options?” 

Her babysitter beamed. “Nope!” 

“Then… peas, I guess?” 

Nodding, Rebecca replaced the other jar, popped the lid off of Mary’s selection, and dug the spoon in to get a big scoop. “Alright, then. Open wide!” 

This is humiliating. 

Mary opened her mouth, let her babysitter scoop the mushy green muck into her mouth, and swallowed. 

It… didn’t taste that bad. It was by no means a gourmet dinner, but the recipe had some actual flavor to it. Mary swallowed, begrudgingly opening her mouth for another bite. 

Rebecca didn’t seem too interested in feeding her with any sort of care or delicacy. Every other spoonful or so ended up on Mary’s face, dribbling down her lips or on her cheek so that Rebecca had to scrape it up with a spoon to get it back her mouth. 

“You’re such a cutie,” Rebecca cooed, taking a moment to wipe her face up with the bib. “Is your baby food alright, little one?”

“It’s…” Mary blushed, kicking her legs a little. “Better than I’d expected.” 

“Of course it is.” Rebecca gave Mary a little pat on her head, then turned back to the drawer and bent down, taking out a heating tray and an oversized baby bottle. 

Oh, right. 

Mary watched as her babysitter mixed formula powder with water and set it on the heater, warming to a drinkable temperature. 

As she sat there, waiting for her bottle, the food settling in her belly, Mary felt something else that she really didn’t want to. Her body shifted, making room for the meal she’d eaten, pushing out waste into the seat of her diaper in response. 

She couldn’t stop it, she couldn’t help it from happening. Shifting uncomfortably in her seat, she started to fill up her diapers, with no chance of getting changed in sight. 

Rebecca eyed her, then giggled as she realized what was happening. “Aww, is the baby having an accident?” 

Cheeks burning, Mary tried to decide if denial would get her anywhere. She ultimately decided it wouldn’t, but at the same time, she didn’t want to just admit it. As a compromise, she crossed her arms and simply refused to say anything at all. 

That just made Rebecca giggle more as she took the bottle off the tray and walked it over to her. “Now, little one, can you hold your own bottle, or do you need Rebecca to do it for you?” 

Mary tried to say, “I can hold it myself,” but when she looked at her hands, she wasn’t so sure. The last thing she wanted to do was promise that she could, then be proved wrong and give her babysitter more fuel for teasing. So, she shrugged again, refusing to make a declaration one way or another. 

Of course, that only got her more amused smirking. “Alright, I’ll hold it for you,” Rebecca said, lifting the bottle up to Mary’s lips. 

Like the baby food, she’d been expecting something repulsive, but instead got something that was absolutely fine, even tasty. Drinking it was painfully slow as she had to suck it through a tiny hole in the bottle’s rubber nipple, but Rebecca seemed patient and willing to let her take as long as she needed to drink the whole thing down. 

Mary also found that, beneath three layers and the plastic pants, she couldn’t even smell her own accident. She could still feel it, every time she shifted her weight, but all things considered… this could be a lot worse. 

Except, of course, for the frustration. The one thing she couldn’t get over was the burning, insatiable desire to be given the climax she’d been denied. 

The bottle eventually emptied, and Rebecca took it away, unlatching the tray. “Okay, little one, let’s get you ready for naptime, shall we?” 

“I guess…” Mary mumbled. 

Helping her down from the chair, Rebecca retrieved a teal onesie from the drawer, unfolding it and doing the snaps at the bottom. “Arms up?” 

Seeing no benefit in arguing, Mary lifted her arms, letting her babysitter dress her in the simple, juvenile garment. “I… How long is this nap going to be?” 

“Until I decide you’ve had enough sleep,” Rebecca said, reaching down. “Lift your bottom.” 

Mary obeyed, and Rebecca reached beneath her, taking the snaps. The onesie was somehow able to contain all the bulk of her diaper, and it buttoned snugly into place. 

Standing up, Rebecca lowered one side of the crib and offered Mary a hand. “Up?” 

“Fine,” Mary grumbled, accepting the hand and crawling into the crib. I guess this isn’t so bad. I’ll sleep it off and wait for this to be… What’s she doing?

Once Mary was in the crib, her babysitter turned back to the drawer, coming out with red leather straps and cuffs. 

“Um…” Mary said, eyeing the straps uncertainly.

“What is it, little Mary?” Rebecca asked, as though she had no idea what could possibly be wrong. Reaching over, she took one of Mary’s legs, bending it and wrapping the strap snugly in place so that Mary couldn’t straighten her leg. Duplicating the process with Mary’s other leg, Rebecca got her snuggly bound, so that she couldn’t possibly stand, or even crawl. 

At least she slipped off the booties, once Mary’s legs were thoroughly restrained. 

Moving to her wrists, Rebecca pulled away her mittens, but replaced them with a pair of cuffs and a small, metal ring with a wire hanging from it that went around her thumb. 

“Now, little one,” she cooed, in her most tender tones, as she connected the cuffs to Mary’s collar with a simple clip. “Your ring has a conductor and a moisture detector in it. So long as it stays wet, it’ll be dormant and do nothing. If it gets dry, though…” She plugged it into Mary’s collar, and as soon as the connection was made, Mary yelped in surprise. 

The chastity belt had an attachment on it it that would do nothing to enforce chastity. It buzzed against Mary, slowly, such a faint sensation that she couldn’t possibly get any satisfaction from it, but strong enough that it was impossible for her to ignore given how frustrated she felt. 

Without hesitation, Mary stuck her thumb in her mouth, deep enough that she could get spit on the ring. As soon as it got wet, the vibration stopped. 

There was no way she could put up with any more teasing, so she really only had one choice - keep her thumb in her mouth until Rebecca unplugged the ring. 

“There you go, little one,” Rebecca said, bending over to kiss her on the forehead. “Now, get some rest. I’ll be back to check on you soon.” 

Mary whimpered, watching her babysitter walk away, flicking the light switch on her way out. 

Squirming, Mary tried to get comfortable. 

On the bright side, she had a better idea of what her weekend was going to be like. 

Two and a half days of this. That’s all, then they’ll let me go. I can do two and a half days of this. 

The vibration started up again, and she realized she’d let her thumb slip too far out of her mouth. Quickly, she reinserted it, to stop the teasing. 

I hope…
