The Ultimate S&M Device

Sirzechs is a very busy man so he didn't insist on asking about the evidence and disconnected the call.

Everyone is silent until Kisuke muttered to himself, "I really look forward to the bet~. I hope Koneko-chan likes my present."

Rias and Akeno reacted to his words, "You're cheating!"

"I'm not. You agreed to my terms, confidently at that. It's not my fault that you can't win." Kisuke smugly replied.

"N-no... But..!" Rias couldn't think of anything to refute his claims.

"G-Give it up, Rias." Sona on the side is stopping herself from laughing but she's failing at it miserably.

"Sona!?"

"If there is one thing that I learned from interacting with him, that is betting with him is just giving him benefits without return." Sona composes herself and explained to her the futility of her actions.

"Why didn't you warn me then?" Feeling bitter, Rias blamed Sona.

"Don't take it out on me. I'm also the victim here. But I must say, seeing others suffer from his tricks makes me feel quite good." Sona heaved a sigh of satisfaction.

Rias pointed at Sona and face Kisuke with her mouth twitching, "Urahara... What did you do to her?"

"Do what?"

"She's acting strange! This isn't the Sona that we knew!" Rias exclaimed and off to the side, Akeno is nodding with great vigor.

"She always acts like that around me though. At first, she likes acting tough, but as time goes, she became more honest to herself." Kisuke recalled Sona's attitude when he first met her.

"No no no. She didn't become honest! Although you're correct to say that she likes acting tough, that is her true and default personality. But now, she can act like a delinquent and she's even started to like seeing others suffer!... You've infected her..."

"How rude! Don't call me like I'm some sort of disease!"

Rias ignored Kisuke and grabbed Sona's shoulders, "Sona! Wake up! That guy is messing with your head!"

"That's wrong, Rias. I'm fine. In fact, I never felt so free before. Fufufu~." Sona is feeling funny after seeing Rias' expression, 'This sort of thing isn't so bad.'

"Y-you...!" Rias was speechless and glared at Kisuke.

"Yoruichi, I make sure I clean myself properly every time I exit my lab, but are there still some of the drugs still on me? Now that I look closely, Kaichou is indeed acting funny." Kisuke crouched down and asks the cat beside him.

"Don't worry, no drugs are on you. And don't act like you're blameless here. It's clearly on you."

Kisuke didn't refute her words because he has some inkling that it really is his fault and he just didn't want to admit it.

"Alright, let's stop this. The day will end without us accomplishing anything if we keep doing this. Let's go to Koneko-chan. She's getting restless." With that said, Kisuke disconnected the magic circle that transfers sound he secretly activated before Sirzechs even started talking.

In the medical ward, Koneko is crying her eyes out and kept muttering her sister's name, 'Nee-sama... Kuroka-neesama..."

Aika is comforting Koneko and looked where Kisuke's communication magic formerly is and sighed, 'To think Koneko-chan has such a tragic story... Compared to me... Just a normal person on top of being annoying...'

While they were all bickering, Kuroka, who's having a hot time alone, heard everything that Sirzechs said and end up crying a little remembering her childhood. But after all of this, from her understanding, Shirone should already know what really happens back then. Kuroka stopped struggling and kept on thinking what this entails, 'Will Shirone forgive me? How did she react when she first time heard it? What if she never forgives for what I had done? What if she doesn't care about me anymore? What if...'

Kuroka ends up getting emotional from anticipation and fear. She completely disregards what is happening outside until she felt someone carrying the box she is in, 'Am I going to see Shirone now? What if she still hates me?...'

Kuroka felt a pulse of magic and the air in the surrounding suddenly change. It's the same feeling she has when she uses teleportation magic.

A few minutes of traveling, Kuroka heard a knock on the door followed by the voice of the hateful human who tied her up 'nicely', "Koneko-chan! Underrated gift or your lovely visitors?"

From the other side of the door, Kuroka heard Shirone's voice, "Gift!" Kuroka has been watching Shirone throughout the years secretly and this is the nearest instance that she heard her voice, 'She knew!?'

Aika opened the door and let Kisuke entered the room, leaving behind the four Devils, Sakura, and Yoruichi. There's an obvious disappointment to Rias' and Akeno's face when Koneko unhesitantly chooses the 'Underrated' gift over her 'Lovely' visitors.

Kisuke saw Koneko's puffy but excited eyes, "Yo~. Koneko-chan! How have you been?" Kisuke gently put down the big white box tied in red ribbon.

"Good. But I'll feel a lot better after hearing everything." Koneko didn't even look at Kisuke as her gaze was already attracted to the box which she guesses that her older sister is in.

"It seems that you can't wait anymore. Well then, We'll leave you alone for now. Goodluck~" With that, Kisuke left the 'hungry' cat alone with its 'food'.

After Kisuke exited the room, Koneko slowly approached the box with excitement and fear taking over her heart and say a note on top of it, 'Pull this ribbon to receive your gift.'

With both of her hands shaking, she reached out for the ribbon but wasn't able to pull it immediately, 'What should I say? What if Nee-sama hates me? Because if not for me, she didn't have to suffer so much... What should I do? Why is Nee-sama aren't making some noise? Did Kisuke senpai did something to her?'

One question after another kept popping up in her head and she slowly pulled back her hands from the ribbons. But just as she did, she noticed a note written on it, 'Don't think too much. If she starts getting angry at you, I'll help you spank her~.'

Getting back her smile, she pulled the ribbon with all her might and the lid of the box flew up with the sides of the box falling outward. Kuroka, who is tied up lewdly with a flushed face appeared in front of her.

The effects of Kisuke's binding spell already disappeared so Kuroka inevitably ended up moving quite a bit to find a comfortable position, but she regretted it now because the knot is really well placed that it kept attacking her sensitive place. Even though she knew that she has to appear serious in their long-awaited reunion, she couldn't help but get turned on a little bit.

When the boxed opened, Kuroka saw Shirone's face directly for the first time in years, but her heart fell when she noticed that Shirone is giving her a cold look. Kuroka avoided her gaze and her tears are already welling up, 'So she hates me after all...'

Kuroka closed her eyes because she felt that Shirone approached her. She thought that Shirone would slap her due to her actions in the past. But contrary to her expectations, Shirone tugged the rope which is binding her and tried to break it using brute force. Although it only ended up digging on Kuroka's various places, "Ahn~."

Both Kuroka and Koneko opened their eyes wide at the sensual voice that Kuroka released.

With a sigh, Koneko went to the corner of the room where an unassuming box is placed. Opening it, she grabbed a giant harisen(white paper fan) that Yoruichi gifted her in the past.

With throbbing forehead, she exited the room. Kuroka heard the hateful human's voice after a few seconds, "Yo, Koneko-chan! You got out earlier than expected. Did something happen? And why are you carrying a giant harisen? And please stop glaring at me... I'm starting to get scared."

A loud slap was heard and it was followed by Kisuke's voice again, "Ow... ow? Ow! ow! ow! What the hell!? Why does it hurt so much!? Hey! Where did you get that harisen!?

"Yoruichi-san..." Koneko answered simply followed by another loud slap.

"Ow ow ow!!! Yoruichi!? What the hell is that thing!?"

"Hehehe... I'm learning from you every day and I created a device that hits you harmlessly but it multiplies the pain. Only masochists can tolerate the kind of pain it produces."

"You created the ultimate S&M device!?"
