They called it simply "the chair". The chair had something for everyone, good girls and bad.
Good girls were allowed to sit down on it until they'd had all the fun they wanted with the vibrating wand integrated in the seat.
Bad girls didn't get the option not to sit down. They also tended to stay seated a lot longer than the good girls.
Sophia had not been a good girl.
"Sure you don't want to apologize?" Cindy asked as she fitted the straps around Sophia's ankles. The chair had some simple, yet effective additions to make sure that once you were seated, you stayed seated.
Sophia giggled. She was having far too much fun in her role. "My Mom taught me never to apologize for the way I am."
"That so? Did your Mom also teach you that prank with the ice cubes?"
"Nope. Came up with that by myself." Sophia rattled the chain links of the ankle straps. Not for any practical purpose; even if she wanted to escape, which she didn't, Cindy's craftsmanship made it utterly impossible. She just wanted to show some fighting spirit. "And it was fun. Your squeal was so cute."
Cindy slowly paced up and down in front of her, her fingers interlocked between her straightened back. She looked stunning in her smart blazer and skirt, as opposed to Sophia who had been stripped of everything and knew that she was looking stunning in her own right. "The defendant does not seem to repent her actions. Is she aware that this will reflect in her punishment?"
"Are you aware that your lawyer impression needs a lot more work?"
Sophia gasped when her girlfriend grabbed her hair and yanked her head back.
"Careful now." Cindy's voice was menacingly low and her eyes sparkled with the intensity that Sophia had come to know and love. "You're about to make things real hard for yourself."
"Oh really?" Sophia's belly tingled. Being smart with Cindy when she was in this mood was a dangerous thing, but Sophia was having too much fun to stop herself. "I haven't made if hard for myself yet? So if I'm careful now, I get off easy?"
Cindy tightened her grip on Sophia's hair. She leaned in, her face dominating all of Sophia's field of vision. "I think it's been too long since I last punished you. You are-" She got cut off by Sophia's tongue flicking her nose. "Okay, that does it." Cindy let go off Sophia's hair and got up, rubbing her nose. "You're not leaving that chair for a long time."
"I've heard that before."
"Of course you have. Because you've always been a bad girl." Cindy picked at Sophia's labia, not even trying to be gentle as she made sure that the head of the wand rested dead center against Sophia's pussy, with nothing whatsoever to dampen the vibrations once she turned them on. The design was so simple and yet so effective. All it needed was a hole in the seat of the chair, wide enough to guide the shaft of their magic wand through it, but too narrow for its head. Sure, the contraption got pretty loud, but then again, so did Sophia after some time on it. And since the wand was socket-powered, they had all the time in the world.
"Any last words?"
Sophia hesitated. This close to the start it was hard for her bravado to persist against the memories of the last times Cindy had punished her with the chair. Even for a masochist like her, there was a point where the fun became fun torture and then further turned into just torture. They both agreed that it would be boring to cut it off before that point was reached, and afterwards Sophia always felt proud of what she'd been able to endure. That didn't make it any easier in the heat of the moment, though, when she screamed herself hoarse as she found out there existed levels of over-sensitivity she'd never thought humanly possible. But then again, you didn't fully live if you didn't push your limits.
"Fuck you," she whispered, grinning to mask her nervousness.
Cindy didn't even honor that with a response. She just raised an eyebrow and switched the wand on. Sophia gritted her teeth, only barely staying silent. This wasn't the low, teasing setting Cindy liked to use as a warm-up. The wand blasted away at what had to be its highest setting. It felt good, no question about it, too good even for someone like her who liked it rough. Sophia would've loved to just close her eyes and let herself fall into these violent vibrations that drilled into every part of her pussy at once, overpowered her senses with pure pleasure. If she'd let herself, she'd have come within minutes, but that would've been foolish. The phase before the first orgasm was the only time she could enjoy the vibrations without the over-sensitivity that would eventually erode her sanity. She had to pace herself. Sophia focused on her breathing. It was impossible to just meditate away the wand at full power, but she could make herself stay above it. Relax herself as she rode the pleasure, fight to suppress the fateful first twitch of her muscles that would make everything come crashing down.
"Why are you holding back? Don't you want to come?"
Sophia didn't rise to the taunt. She needed her focus. The vibrations were relentless. So far she was staying on top of them, but just barely. Breathe in, breathe out. Breathe in, breathe out. Don't focus on anything else. Not on Cindy's teasing and definitely not on how good that wand felt and how her clit was almost going numb from the onslaught. A hot tingle festered in her loins. The pleasure built up, threatening to boil over any second.
Cindy giggled. "You should see your face right now. You look like Buddha when he really needs to take a shit."
It was such a stupid line that it broke Sophia's focus for a moment, which was all it took. The needs of her body overrode her mental control and she involuntarily clenched down against the vibrating head. For a second Sophia tried to fight it, but what was the point? The orgasm was happening either way, so she might as well enjoy it.
