The expensive dual vibrator

Both toys looked really interesting, and while Mercy liked the idea of the long-term training benefits of the Ben Wa balls, she really didn't anticipate this urge lasting long enough to benefit from it. The sales pitch for the little pink thing had Mercy's pussy practically drooling, and after all, she was doing this to satisfy her new random fantasy so she followed that urge.

"This one."

The woman nodded with a smile. "Good choice. You are going to love it. Make sure you read the instructions first, or take your time playing with it where you can afford things getting a little crazy. It can take a little getting used to."

Mercy was starting to feel the time pressure to hurry. "Yes, I will." She knew it was a lie. That thing was going inside her at the first opportunity and she would sort out the rest later. She checked out, surprised at just how pricey the thing was, but the woman reassured her that it was going to be well worth it, and it came with a five year warranty in case she wore it out. The cashier had laughed a little when she said that, as though it would be crazy to run it so much it wore out in five years.

"Have fun, sweetheart! And come back any time. Life is short but pleasure sure helps."

Mercy hurried back to her car, staring at the toy she'd just spent a week's food budget on. She should have been more responsible than that, but she just couldn't stop thinking about it. She needed it immediately.

Inside her car, she ripped open the box and examined the toy. Its texture was rubbery and soft, almost slick, but she didn't see any buttons or controls; no way to turn it on. The box included a few disposable, vag-friendly sanitary wipes and a tiny packet of lubricant, so she cleaned the thing for good measure and then paused. How exactly was she supposed to do this in a car?

After a brief moment's deliberation, she realized she didn't really care how she did it, she just needed it to happen. So she hiked her skirt up around her waist and pulled her panties down to her knees, trying awkwardly to find a position on her seat that would accommodate her figuring out how exactly to get it on. She only hoped no one walked by her car because her windows were not tinted. Somehow, the idea of someone seeing her in such a lewd, compromising position actually excited her all the more so she just went for it.

She threw open her car door and climbed out to completely remove her panties and squat beside her car. The lubricated toy slid easily into place. Finally.

The bulb wasn't huge, but she definitely felt it inside her. Much more distracting was the broad clamp that gently gripped her clitoris. The surface was covered in tiny grooves to help keep it from slipping off of her, and the gentle grip of the U shape allowed the whole thing to just... stay. She stood up and gasped softly at the way the motion pulled at her clit. Just a little tug, not uncomfortable at all, but impossible to ignore. She pulled her panties back up and smoothed her clothes, looking at herself in the side view mirror of her car. There was no sign at all that anything was out of the ordinary. Completely invisible. Good.

Mercy jumped back into her car, again realizing that every little movement was going to bring a certain amount of surprise stimulation with it. She loved it. But still, she needed more.

After a quick search of the box, she found a paper card inside that contained a QR code to download the app that would control it. The card promised that it was a unique code for her device, so the app wouldn't need any additional configuration to just work. There was a small book of instructions, but it was like thirty pages. She didn't have time to go over it.

App downloaded. The interface presented five buttons, but she wasn't interested in a full tour. One button was labeled "Modes" and she tapped it, finding more options than she cared for. She didn't want to program it, she just wanted to turn it on.

She did find two modes labeled "Tease" and "****," as the woman had described, so she just tapped "Tease."

Immediately, the thing between her legs came to life, buzzing intensely, making her nearly jump out of her seat. Mercy gasped, releasing the breath in a slow, shuddering moan. The vibrations lessened gradually until Mercy felt she could handle them easily enough, and the intensity remained low and consistent for a few minutes. Her entire body tingled with excitement.

"Okay, wow. This is fucking hot."

Tossing the torn box and the little book of instructions into the back seat of her car, she started it up and pulled out onto the road, feeling more alive than she ever had before.
