The Product Tester - Chapter 7

Art by HofBondage

Mary ate dinner across from her fiance, feeling a bit sheepish about the day’s events. 

On the one hand, she’d learned a lot about the diaper cover, how it functioned, and what she’d have to overcome to get out. On the other hand…

“Fuck me, I don’t know if I can go another twenty nine days without sex,” she groaned, voicing the complaint that had been floating around at the back of her mind - and between her legs - since she’d sobered up. 

Ethan paused, midway through a sip of water. Lowering his glass, he asked, “Uh, oh?”” 

Mary nodded, rolling her eyes. “I would have had a shot, but stupid high-as-balls Mary decided that she was going to get just a second from climax a couple times so I’d be frustrated and crotchety. Why couldn’t the drugs have just tranquilized me?” 

“Safety hazard,” Ethan said, apparently glad to change the topic to something technical. “The cocktail we’ve got right now is designed to leave you able to respond to immediate stimuli, in case there’s some kind of disaster. If there was some kind of disaster, like a fire or a car crash or whatever, you’d still have the wherewithal to get away.” 

“Still seems like a massive hazard,” Mary hedged, cutting up her pizza and taking a bite with a fork. “What if it gave me too much and I overdosed? Or what if the danger was too complicated for me to get away while stoned?” 

“For the former, you were given a complete physical beforehand and the injection is scaled to your weight and mass distribution,” Ethan explained, folding his pizza in half New York style to take a bite. Talking with his mouth full, he added, “And in case there’s a more complicated risk, that’s where I came in.” 

“Oh. Interesting.” Mary smirked, cutting off another piece of pizza and chewing, letting Ethan puzzle at what she meant. 

His curiosity won over before she could swallow. “What’s interesting?” 

“Nothing,” Mary said, letting her smile widen. If he can come to my aid at any point, then the cover must have some kind of GPS tracker, and an alert system for him to know where I am. Good to know. “Do you suppose you could let me out of these for an hour or so, so I could jump your bones?” 

Ethan chuckled, not realizing what he’d given away. “Kat explicitly warned against letting the test subject seduce me.” 

“I’d be good!” Mary said, smiling innocently and biting her lip. “Don’t you trust me, sweetie?” 

Ethan couldn’t keep the flicker of interest off his face, but he kept his answer firm. “No.” 

“Well, damn.” Mary sighed, eating another bite of pizza.
“It was worth a shot.” 

Her fiance smiled, knowingly. “All just a shot to get out of the cover, eh?” 

“Not just that. I do wish we could put the experiment on hold for half an hour. Or, like, five minutes.” Mary shrugged, covering her blush with a drink of water. 

Ethan hesitated for a moment before he said, “You seemed to be getting along fine earlier, even with… everything you were wearing.” 

She nearly spat out her drink. “No way in hell. You had the right idea in stopping me. I’m not about to sink that low.” Pushing up from her seat, Mary waddled to the counter, rinsing off her plate so she could put it in the dishwasher. 

Ethan chewed on his crust, thinking it over, then suggested, “You know, you’re not in a diaper all the time.” 

Mary hesitated in the middle of bending to open the washer. “What are you suggesting?” 

“Well…” Ethan said, blushing brightly. “You see… When you’re on the changing table, you’re not wearing a diaper, but you’re also not going anywhere.” 

Reflexively joking, Mary said, “Kinky.” Upon further reflection, though, she realized that the description was pretty apt. “Was this just an elaborate excuse to get my to try bondage?” 

“No! Absolutely not. But…” Ethan rubbed at the back of his neck. “It’s a possibility, anyways. Forget it, it’s a stupid idea.” 

“No, it’s not,” Mary said, shaking her head. “Let’s try it.” 

Ethan blinked in surprise. “Really?” 

“Worst case scenario, we’re back at square one.” 

Internally, Mary wasn’t so certain, but the tingling and warmth between her thighs made her willing to try anything. 

Wait, warmth? Frowning, Mary slipped a hand down the front of her pants, feeling the front of the diaper. “Oh.” 

“Oh?” Ethan asked, cleaning up his own plate. 

“I think I’m peeing,” Mary explained. “When’s my next change?” 

Her fiance checked his phone. “In about an hour.”

“Are you up to… trying things then?” Mary asked. “I don’t really feel like waiting.” 

He didn’t answer right away, but Mary knew what he was thinking just from his expression. Yes. 

…

Lying on the mat, arms locked over her head, feet cuffed in place, Mary was not as certain as she had been. Her rampant horniness hadn’t gone away, but bound and immobile as she was… 

“Are you sure about this?” Ethan asked, depositing her old diaper in the pail. “It’s all up to you.” 

“I’m sure,” Mary lied. “Let’s go for it.” 

Kneeling over her, Ethan smiled warmly. “You’ll tell me if it’s too much?” 

She rolled her eyes. “Duh.” 

With that in mind, her fiance leaned down, fingers playing between her legs in a slow rhythm.  

He started gently, playing on the outside, tracing his hands in slow, teasing circles. The pervasive frustration that had been with her since she’d been interrupted that morning all rose to the surface, more intense than ever with his gentle touch. 

Mary arched her back, trying to move her hips in time with the motion, but with her arms firmly buckled down there was little she could do. The restraints rendered her a passive participant, helpless against Ethan’s touch. 

“Good?” Ethan asked, bending over, holding himself up with an arm so he could plant small kisses on her neck. 

She bit her lip. I’m fine. I can deal. “Y-yes.” 

At that, Ethan ramped up the speed. He hadn’t gone inside yet, fingers still playing against her sex as foreplay, but that sensation was more than enough to elicit a quiet moan. 

Moving her feet, Mary felt the leg cuffs shift with her, limiting her motion, keeping her held down. She couldn’t move away, she couldn’t respond. She was trapped. Helpless. Incapable. At his mercy, to-

“Babe?” Ethan asked, pulling his hand away. The frustration was sudden and intense, but she still felt relieved.

“Why’d you stop?” she asked, in spite of herself. “Keep going.” 

“Your eyes are wet.” He wiped at her cheek with the back of his hand, and it came away damp. “Are you sure you’re okay?” 

“I…” Dammit. She swallowed her pride and shook her head. “No.” 

He kissed her cheek, sitting up. “That’s fine, babe. We don’t have to keep going.” 

Unaware that she’d even been holding it, Mary let out a breath in relief. “Are you sure?” 

“That’s not even a question,” he said, tone as certain as his words as he sat up and pulled away, zipping up his jeans. “We’re not going to do anything you’re not totally on board with. How about I get you changed, and then we’ll break out the ice cream and watch TV?” 

Nodding a couple times, Mary responded quietly. “That sounds nice. I love you so much.” 

He kissed her, gently this time, with nothing sexual in the gesture. “Of course. I love you too.” 

…

It was almost midnight, and Mary couldn’t sleep. 

In spite of, or perhaps because of, the failed attempt a few hours before, she was still as horny as ever, and her body was unwilling to give up its clamor for sex. 

She tried rolling onto her side, but that felt awkward and uncomfortable with all the bulk between her thighs. 

As tired as she was, getting to sleep seemed unlikely to happen any time soon. Unless she could get her body to shut up, or just deal with the problem directly, there was only so much she could do. 

Ugh. Fuck it. 

Ethan was fast asleep, snoring quietly, too out of it to notice if a truck passed through the room. Nobody would know except her, and she was past the point of caring. 

Quietly, without moving around too much, Mary reached to the drawer of her night stand, fished around blindly for a moment, and produced her wand. 

Plugging it into the wall socket next to her phone charged, she held the toy for a moment, made up her mind, and turned it on. 

As much as she’d used the toy in the past, simply hearing the buzz was almost pavlovian, except that it wasn’t her mouth that grew wet. Uncertainly, she touched the vibrating head to the front of the diaper, eased it into the right spot, and pressed it down. 

“Oh, fuck.” She kept her voice to a whisper, but otherwise couldn’t prevent the audible reaction. Clutching at the sheets with her free hand, she increased the speed, pressing harder into the crinkling plastic cover. 

She couldn’t tell if the diaper was wet or not, not with all the dampness from inside her, but the thick diaper spread out the vibration, amplified it, making the sensation more intense than anything she’d ever gotten out of the toy on its second setting.

Gasping, Mary rolled her hips into the wand, rocking the bed a little. She no longer cared if she woke Ethan, all that mattered was the burning desire between her thighs, the fire, the need…

“Ffffuck!” she cried out, loud this time, as the vibrator all but ripped a climax free from her. “Oh god, yes, yes, yes-” 

Warmth and pleasure overcame her, and hot on their heels came relief. It was only because of all the denial and frustration of the day, or at least that’s what she told herself, but she couldn’t remember the last time she had finished that hard, that fast. 

The comfortable pleasure that overcame her was complete and wonderful, and as she turned off the wand, she finally felt ready to get some rest-

“Babe?” Ethan asked, leaning up, sleepy and confused. “What’s going on?” 

“I, uh-” Mary started. Oh, dammit. “It’s nothing, go back to sleep.”

Too late. He turned on the lamp, casting Mary and her vibrator in stark light that left nothing too uncertainty. 

“Um…” she mumbled, face burning with embarrassment. “I…” 

Her fiance smiled, showing no sign of teasing or mockery. “Did you have fun?” 

Blushing deeper, Mary admitted, “Y-yeah.” 

He leaned over and kissed her on the cheek, then turned out the lamp. “Good. I’m glad you found something that worked for you.” 

She set the wand aside, trying not to sound as mortified as she felt. “You don’t… think it’s weird?” 

“Of course not.” Ethan took his phone from the bedside, checking a notification. “I’m just happy for you.” 

Mary sank back into her pillow, relieved at the lack of judgement. Glancing over, she also couldn’t help but see what was on his phone. 

It was an app she didn’t recognize, but she still managed to read a bit of the text on the display before he turned it off. ‘Recent wetness increase; 23% capacity reached’. 

He gets phone notifications about my diaper? 

That was something to worry about in the morning. For now… “Uh, would you mind if I went again?” 

Ethan laughed softly, only audible as a puff of air. “Not at all. Do you want some help?”
