Work Text:
Kaeya sat comfortably upon his sofa, sipping a glass of his favorite wine as he pored over some documents that he should have checked at work, but it slipped his mind. Better late than never, he thought.
Fortunately for him, it was nothing too urgent, just simple things he needed to be aware of in upcoming events. It all seemed easy enough, but he had to take a moment to admire just how much thought went into Acting Grand Master’s words when writing this out.
She always did have a way with words, Kaeya smiled.
He was pulled out of his thoughts when he heard the door creak open. His gaze lifted to see Albedo entering the room, closing the door behind him.
“Ah, if it isn’t my favorite Alchemist.” Kaeya greeted before sipping from his wine glass.
“Kaeya. Will you be my test subject for my latest experiment?”
Kaeya lowered his glass from his lips with an amused chuckle, Albedo was straight to the point as usual. “Hello to you, too.”
He watched as Albedo travelled closer, clutching a clipboard in his arms. His long boots loud against the floor he walked on.
“Hello,” Albedo stood directly in front of him, Kaeya instinctively uncrossing his legs so that Albedo could occupy the space in between, however Albedo kept a professional position today and opted to stand just before his knees instead. Kaeya couldn’t help but feel a small twinge of disappointment.
“What exactly do you mean by test subject?” Kaeya placed his forgotten documents to the side table seated next to the sofa.
“A test subject is typically a volunteer who participates in human subject research to assist in-”
Kaeya’s chuckle interrupted the alchemist. “No, dear. I’m quite familiar with what it means. I just meant, what is it you would like me to do as your test subject?”
“I see,” Albedo checked his clipboard briefly, he most likely wrote notes on what Kaeya’s position as test subject would be there. “Well, I’ve created this new device that I would like you to try on.”
Kaeya raised a brow and gave a curious tilt of his head. “A device? That sounds very ominous.”
“I can assure you that there is nothing to fear. It was not created with the intent to harm the wearer, but I would like to test the results of the effects it can provide.” Albedo explained and Kaeya couldn’t help but drift in Albedo’s passionate expression. “Is that alright?”
“Hm. I’m not sure,” Kaeya leaned back against the sofa cushions, audaciously amused by the look of confusion written all over Albedo’s face, he almost looked shocked by Kaeya’s early dismissal. “What if something were to go terribly wrong and I were to be harmed in the process?”
“I wouldn’t ask you to test it if there were any risk of that happening,” Albedo assured, finally taking the offered standing space between Kaeya’s legs while he sat. Kaeya couldn’t hide his smile and leaned forward to wrap his arms around the blonde, looking up at him fondly.
Albedo made sure that the clipboard wasn’t in the way when Kaeya embraced onto him, which Kaeya was grateful for. “And do I get a reward for my efforts?”
“Oh, I would say so,” Albedo finally smiled, a tint of red decorating his cheeks at their closeness.
“Then how can I refuse. Where is this device of yours?”
~*~
Once inside Albedo’s work study, Kaeya found himself looking at a strange looking device in Albedo’s hands, which was held out to him.
“Is that a belt?” Kaeya questioned, observing the shape of the purple device.
“That is the object I based its appearance on, yes. Very easy to wear.” Albedo explained, undoing the buckle and stepping closer to help put it on. Kaeya lifted his arms, a little sceptical but still willing to participate while Albedo places the belt around his waist.
“And you’re certain this won’t hurt?”
“I give you my word,” Albedo gave him a reassuring smile before stepping away back to his desk, where there sat a small remote control. “Now, this belt has three different level of settings installed. When I switch it on, you will start to feel a small sensation emanating from the belt. It will automatically start at the lowest setting, and after a minute, we will progress to the next, and then again until we reach the end. If at any time during the experiment it becomes too much, please say stop. Simple?”
“It sounds simple enough.” Kaeya looked down at the belt that hugged his waist and gave it a small adjustment with his thumb before crossing his arms across his broad chest. “When do we start?”
“Right now,” Albedo flicked the switch, and Kaeya felt the belt come to life. It emitted a gentle vibration that sent tingles across Kaeya’s belly, and he squirmed at the unexpected sensation, struggling to maintain his usual composure.
“Ah – heh, t-that feels different,” Kaeya stuttered, unsure of what the purpose of the belt was even for with these tingly sensations. “Is – ahem – is this for massages perhaps?”
“We can properly summarize after the testing is complete,” Albedo explained, his attention turning back down to the remote in his hand. “Before I up to the next setting. How would you describe this feeling you’re experiencing right now?”
“H-Heh, kind of tingly,” Kaeya admitted truthfully.
“Noted. Now, let’s proceed,” Albedo didn’t even wait for Kaeya to agree before flicking to the next setting.
“Am I supposed to- Ack!” Kaeya heard himself gasp when the vibrations of the belt increased, spreading across his torso with much more intensity than a pleasant tingle. This time, Kaeya found himself struggling to maintain his composure at all. A chuckle escaped his lips.
“And now?” Albedo asked, clearly noticing the change in Kaeya’s body language as he struggled to remain still, and small laughs escaped him.
“D-Definitely more – ahah, intense!” Kaeya replied, his hips swaying to try and rid the belt from his body but with no luck. It just looked like he was doing a funny dance, which he heard Albedo give a small chuckle at. “Is thihis normal?”
Albedo hummed with a nod. “Everything seems perfectly normal thus far. Your reactions have been expected. Now for the final setting.”
“W-Wait!” Kaeya panicked, he could barely take this recent setting but before he could protest any further, the setting had been turned up. “Ahahaha!”
The belt vibrated and danced furiously against Kaeya’s waist, sending huge waves of ticklish sensations across his entire body. Kaeya doubled down with laughter, trying to squirm around to rid himself of some of the intensity but was trapped within the belt’s ticklish clutches.
“How is it now?” Albedo’s voice just made it over Kaeya hysterical laughs.
“Ihihit tihihickles!” he wheezed, even snorting a little when his legs finally gave up holding him up, weakened by his laughter he slowly fell to the ground. “Ahahahalot!”
“I can see that,” Albedo said, sounding smug? Kaeya looked up in attempt to confirm his suspicions and there it was, clear as day, a smug expression sat upon Albedo’s face.
That little sneak.
“Yohou little – Bahaha!” Kaeya couldn’t even get a full sentence out, being driven mad by incessant tickles that no matter how much he squirmed, he couldn’t escape from.
“Subject seems to be reacting just as expected,” Albedo began taking notes on his clipboard, that smug smile never once faltering. “I suppose it does help that I know just how responsive to you are to being tickled.”
“Mahahake it stohohohp!” Kaeya cackled, using his hands to cover his face that now turned bright red from laughter. “Plehehease!”
After what felt like an eternity, the belt ceased its movements and Kaeya was finally allowed to breathe. The room that was filled with sounds of laughter, now quietened down to heavy breathing as Kaeya tried to capture his breath and soft scribbles of Albedo writing.
“You dearest, are a mad scientist,” Kaeya narrowed his eye up at the blonde, who responded with a genuine chuckle of amusement. Kaeya could feel himself melt at the sound. “Did you really make that just for me?”
“I did, and I’d say that it worked perfectly.”
“You certainly got me, that’s for sure. Although, I hope you realise that after this, I will be declining all your requests to be a test subject from now on?”
“I’m sure you will reconsider,” Albedo smiled down before offering a hand out to his exhausted test subject. Kaeya accepted and with the blonde’s help, he was lifted from the ground back on his feet. “You’re free to take that off now. Unless you would like to go again?”
“I’m good.” Kaeya chuckled before unbuckling the belt himself and taking it off. He idly rubbed away at the spot the belt left before continuing. “I do believe I’m owed a reward.”
“That’s true. What would you like?”
It was Kaeya’s turn to look smug as he twirled the belt on his finger, holding it towards Albedo in a subtle hint.
Albedo gulped.
