...a key?

Kara went over to a small unmarked bag that I hadn't noticed was by the sofa. She pulled out a tiny box and brought it back to the table, handing it to me with a small smile. Realizing she was waiting on me, I opened it and saw...

"A key?"

She nodded excitedly.

"For what?" I asked, "I already have one for the apartment, and it doesn't look like a car key..."

Kara pointed to Diana and barked, "Show him."

"Yes, Mistress," Diana said, and lifted the skirt of her uniform to reveal that she was wearing a chastity belt underneath that had the Wonder Woman logo painted on the band that circled her waist.

Kara grinned in excitement. "The other day, I realized that if Wonder Whore here is having trouble controlling her urges, it might be better if we kept her locked up so she doesn't get in trouble when we aren't 'supervising' her. That belt has two keys, one of which you're holding right now."

I fiddled with the key in my hand a moment before looking up at her, "I'm guessing you have the other one?"

Kara pulled an identical key out from her bra, "Yup! From now on Diana will need permission from one of us if she wants to pleasure herself in any way. Fun, right?"

"It could be," I admitted, my dick twitching as I glanced over at Diana again, "But if she wanted to, couldn't she... you know, break out? It's not made of any special super metal, is it?"

"No," Kara said with a hint of disappointment, "I was tempted to call in a few favors and get one made out of Nth metal, but getting one of those in Diana's size right now might raise too many red flags. Maybe if things cool down in a few months we can have her get one for herself, but for now we'll have to rely on the honor system, and surprise X-ray vision inspections, to make sure she stays in it. And if I catch her not wearing it when she should be... well, we can decide what her punishment should be together."

"On my honor as an Amazon, I swear to keep it on for as long as you want me to," Diana said with a blush.

"Good girl," Kara said, before turning back to me, "So, what do you think? Pretty hot, right?"

"Not gonna lie, just hearing Diana say that is hot," I admitted, "But... are you sure she'll still be... you know, like this, in a few months?"

"It's not like we're having much luck finding out what's causing her weird behavior," Kara said with a frown.

"None of her villains could have done something like this?" I asked.

"Not that we've looked into," Kara replied.

It was very quick, but I managed to catch her gaze flick away from me for the briefest of moments. On a hunch, I asked, "Well have you found any kind of lead so far?"

"N-Not really," Kara responded hesitantly. This time the guilt on her face was clear as day.

"Kara... how much have you actually been looking into this?"

"I've been looking!" Kara said with a whine, before mumbling, "Sorta... I've been busy with... hero stuff."

"Like getting a chastity belt for Diana?" I turned to the Amazon princess in question and asked, "When was the last time you two actually spent time trying to find out what's causing your behavior?"

"Two weeks ago," Diana answered, causing Kara to squirm in her chair, "I had an idea that Doctor Poison might have **** me with something, but we weren't able to find any evidence of such before she got away from us."

"And you two haven't followed up on this at all since?"

"No Sir," Diana said, dropping her skirt and looking down at the ground shamefully.

I sighed, "Look, I know you're having fun with dominating her Kara, and it seems like she's liking this too. But we can't just ignore that there could be something wrong with Diana, and that if it could happen once, it could happen again. We need to find what's causing her behavior and put a stop to it before it gets worse."

"...do we though?" Kara asked quietly.

I was floored by this response, "What?"

"I mean, we don't even know if there is anything wrong with Diana!" Kara said, "For all we know she really is just a crazy slut who's got the hots for you."

She flinched as I gave her a glare, then continued, "B-But even if someone did do something to her, they haven't actually done anything with it yet. For all we know they got spooked, or don't think it actually worked, or maybe it was meant to do something else but had her fall in love with you instead. Point being, if this was an evil plot of some kind, they would have done something by now. So there's no need to worry about it."

"But you don't know that, do you?" I countered, "What if she loses control again? Do you want her to try and **** me? Or something even worse?"

Kara started to tear up, and I immediately felt like shit for pulling that card, "Kara, I'm sorry, I know you don't... but this could be serious. Even if you don't think there's anything wrong, we should be sure, right?"

She nodded slowly, "You're right, Charlie. And I'm the one who should be apologizing, not you. I... I'll take this more seriously in the future."

"Thank you." I took a bite of the lamb, "This is delicious, Diana."

Diana gave me a quick bow, "Thank you Sir."

"So, who else besides Doctor Poison could alter your behavior without you knowing about it?" I asked as I continued to eat.

"Well, Circe's magic could be responsible, though given her own distaste for men I doubt she would do something like this, even unintentionally. There's also Hypnotic Woman, but I haven't seen her in decades so I'd be shocked if she was somehow behind this. Personally I think the most likely culprit after Poison would be Doctor Psychooooooah!" The last name became drawn out as she jumped in place.

"Are you okay?" I asked her.

"I-I'm fine, Sir..." she said shakily, her eyes wide. In the silence that followed, I heard a very faint buzzing sound.

I looked towards my girlfriend. After a brief moment, Kara held up a small pink remote with a sheepish grin, "Oops... I forgot I had that on a timer."

"Let me guess: vibrating buttplug in her ass?"

"Dildo the size of your dick, but yeah pretty much." She tapped a button on the remote, putting a stop to the buzzing.

Diana visibly relaxed, "Thank you, Mistress."

Kara slid the remote across the table to me, "This is yours too, by the way. I was hoping maybe after dinner we could have a bit more fun with it? I had this whole thing planned with ice cream and chocolate syrup..."

I put a hand over the remote, thinking over the tempting offer. Eventually I said, "Only if you two promise to look into this Doctor Psycho woman as soon as possible."

"We will, I promise," Kara said.

"Though Doctor Psycho is a man, not a woman," Diana corrected.

I raised a brow, "Really? Huh... I always thought all your villains were women."

"Why would you think that?" Diana asked, tilting her head ever so slightly.

"Well because you're... well... um... uh... you know..."

"I'm what, exactly?" she asked, her tone now starting to drifting away from the submissive and towards the irritated.

An awkward silence filled the air as I fidgeted under Diana's rapidly hardening glare. Just as she opened her mouth to say something else, I quickly hit the power button on the remote and cranked the vibrator to its highest setting. What followed was a loud moan as Diana did her best to remain standing.

"So what's that thing you wanted to do with the ice cream?"

Kara broke into a wicked grin, "You clear the table, I'll get her ready."

In less than five minutes, Diana was lying across the table on her back, with three flavors of ice cream arranged in a line of scoops down her stomach and her breasts coated in chocolate syrup. Kara and I proceeded to try and eat the ice cream off of her before it melted, and licking the chocolate off of her boobs. The whole time the vibrator in her ass (which had been turned down to about half the intensity of before) would periodically turn on for about fifteen seconds at a time, and if Diana moved too much or made too much noise, Kara would flick whichever one of her nipples was the cleanest, then re-coat it in chocolate. By the time the ice cream and chocolate were finally cleaned off of her body, Diana's nipples were red, swollen, and rock hard.

"Please..." Diana panted, one of her hands pawing at the metal belt covering her crotch, "Let me out..."

"Ask properly, and I might," Kara said.

Diana took a few seconds to collect herself, then whimpered, "Mistress, may you please let me out of my belt, so I can touch myself like the needy Amazon slut that I am?"

Kara patted her on the cheek and whispered 'good girl', then turned to me, "It's up to you. Personally, I'd like to leave her like this all night, preferably while she watches us have sex. But if you think she's had enough, go ahead and unlock her."

I pulled the key to the chastity belt out of my pocket and turned it over in my hand in thought.
