Hey everyone! Sorry it took me forever to update! I just couldn't pick one from all the filth I have in my mind! :D
Disclaimer: I do not own Beyblade or Kai Hiwatari (no matter how much I wish I did) I do own the Kyra Valkov character though.

Just a heads up: This one is a little more hardcore and was kind of a request. So..Read at your own risk :)

Kai was trying to convince Kyra to move in with him, stating that the BBA Hotel was just too far away and lonely; the real reason was he was just afraid of losing her again, even though he knew he could always track her down. The moving in, however, didn't come without its share of arguments between the two.

"Doesn't the dojo belong to Tyson?" Kyra protested for the millionth time, every time Kai would bring it up.
"Yes, but I told you, I'm buying my own place, we could really live together then, this is temporary" Kai said, trying to keep his irritation in check.
"Shouldn't you ask him before 'girl-you-are-sleeping-with' moves in?"
"We are more than that!" Kai protested, he didn't say what, just avoided an explanation, "trust me, he won't mind"
"I feel uncomfortable, I barely know your teammates!" Kyra continued her whining.
"There isn't much to know, Tyson eats like a pig and is obnoxious, Max is always on a sugar-high, Kenny has a laptop for a personality and Rei," Kai paused, "Rei is the chef" Kai rolled his eyes as he talked about his teammates, "and I, I am their babysitter, even after being together for 3 years" Kai shook his head.
Kyra gave him one of her judgy looks, "You like them, or else you wouldn't have stayed"
"Hey I stayed because Mr. Dickensen made me!",
"Kai, the abbey couldn't contain you, I doubt a sweet old man can force you into being a wet nurse. Just admit it, you like them", she continued as she walked up to him and wrapped her arms around his neck. "It's okay to like people, you don't always have to hide behind the tough exterior" Kai glared daggers at Kyra, but she pushed her luck anyway, "I know you have a soft mushy centre" she said in mock-baby talk, lightly poking his muscular arm.
"You listen to me, this is your first time so I'll let you go with a warning, if you ever and I mean ever do that again, I will punish you and it WILL be bad" but Kyra was having too much fun, "Oooo wittle-Kai doesn't want people to know he has feeeeeeelings" she continued, giggling.
That did it, Kai pinned Kyra to the bed and turned her around. He then sat on her and wrapped her hands around her elbows and tied them up with his trademark scarf, he then brought her feet together and tied those up to: it was a very neat hogtie.
"Last chance, apologize and I untie you; because I like your face"
Kyra giggled, "No way! You are on your way to play out a major fantasy of mine"
"Maybe I'll just leave you tied up and not touch you at all, the disappointment will be punishment enough" Kai said with an evil grin.
"I will kill you, Hiwatari!" Kyra gave him her own death glare.
"I don't see what you can do in that state" Kai said matter-of-factly, trying to stifle a laugh.
"You'll untie me someday, then I'll kill you"
"You're cute when you try to act all tough in front of me" Kai said, patting Kyra on the head and walked over to his desk. "I have some stuff to do, don't go too far".

Kai brought a bag to the bed and ran a finger down Kyra's leg, he could see her shudder from the touch.
He slipped his hand under her skirt and pulled off her panties and then slid a finger into her pussy, "Wow! You are really wet!", he exclaimed.
He then pulled out a vibrator ran it along her opening, placed it on her clitoris and hit the on button. Kyra's upper body almost bucked up because with shock.
"OH! MY! GOD! KAI!" she screamed, "WHY THE HELL DO YOU HAVE A VIBRATOR?!".
"Torture devices", Kai said with a smirk

"Bought them for you last week, I knew you'd try to pull something like this at some point"
"Device-s?! You have more stuff?" Kyra sounded half skeptical, half excited.

Kai touched the vibrator to her clitoral hood, occasionally moving it around to see the effect it had on his little prisoner, it was always greeted by sharp intake of breath or an extreme twitch in the leg or an upper body bucking that reminded him of sitting on bulls. This supposed torture went on for a good ten minutes.
"Oh and by the way, you have to ask me for permission to cum, okay?" and struck her ass sharply with a paddle,
"Okay!" Kyra was too weak in the knees to argue,
"You will also address me as Master" he struck her ass again.
"Yes Master" Kyra whispered, her breathing uneven.

He then got on the bed, leaned over and began to lick Kyra's vaginal opening, keeping the vibrator firmly at the clitoris and moving it ever so slightly. Kyra's juices were dripping and her legs began to shiver and the pelvic muscles began to contract.
"Master! May I please cum?" came Kyra's breathless plea, Kai was really impressed she remembered, he had expected to have to spank her as a reminder.
"Not yet" he increased the speed and intensity on the vibrator and started to rub it around her clitoris making Kyra scream.
"OH GOD! Please let me cum! Master Kai please!" Kyra's voice seemed hoarse.
"Hold it in little kitten" He was having too much fun, along with the motions of the vibrator he started to finger her – he made a 'come-hither' motion with his two fingers inside her, that made Kyra writhe from side to side, screaming in agonizing pre-orgasmic pleasure.
"Master please! I cannot hold it any longer. PLEASE! OH! GOD! LET ME CUM!" Kai decided it was time, "Alright kitten, cum NOW!" Kyra's screaming grew higher in pitch and she lifted up her lower body off the bed as much as her restraints would allow her, her muscles contracted, her toes curled as she let go of the control she put herself under upon Kai's command.

She lay panting on the bed for what seemed like a long time even though it was barely a minute, her eyes barely open, chest heaving, her body desperate for breath from the strong orgasm she just had. She felt Kai's lips touch hers and he pulled her in to a deep, passionate kiss, as if reassuring her that he would never actually hurt her.

"That was the greatest orgasm I ever had" Kyra whispered to Kai in hushed tones when they broke apart, as if she was too shy to admit it. He kissed her again and simply said, "I am not done with you".
"I really don't see how you're punishing ME here" she replied, happily.
"You will" Kai smirked.

Kai then brought out a pair of bondage cuffs and locked Kyra's wrists behind her back. He unzipped and slid his pants off slowly, just to tease her a little, he then slipped his thumbs in his boxers and pulled them off too. Kyra was struggling with her restraints, the urge to want to touch him, to grab and hold him, to devour the magnificent beast taking over her and all she could really do was tug at her restraints.

Kai then placed a ball-gag in her mouth and secured it in place around her head, using another pair of bondage cuffs he secured her ankles together and attached a line of rope to the cuffs - connecting the wrists to ankles. He then lifted her up gently and placed her down on the floor against the bed, on her back, with her arms and legs raised and her womanhood completely exposed, providing him with unrestricted access to it – for him to whatever he pleased with it. Kyra had absolutely no control whatsoever.

He ran a finger up and down her slit, Kyra was soaked and looked like she was really enjoying herself. He spread his legs a little – placing one on either side of her and lowered himself into a squatting position and slapped her pussy with his cock a few times before he slipped it into her. He started fucking her; gently at first, gradually increasing the speed of his thrusts, hitting her g-spot hard making her scream through the gag, all the while rubbing her clitoris with his finger. Kyra's breathing got heavier and more labored as she started to get close to climax – and Kai pulled out in time, receiving an angry, dirty look from Kyra.

He lifted her up again and placed her face down on the edge of the bed. He adjusted the ropes in a way where Kyra's legs were spread but her feet touched each other completely and crossed her wrists together. He found a hair tie and tied Kyra's now messy hair into a loose ponytail. The bed was high enough for Kai to enter Kyra with ease while he was standing up. She was still soaking wet and his strokes were a lot rougher than they had been the whole time, sounds of flesh slapping flesh filled the whole room. Kai's balls were slapping Kyra's clitoris providing added stimulation – Kai spanked Kyra hard on her ass multiple times as he fucked her; the endorphin in her system dulling the pain and only providing pleasurable sensations, making her want more but she was only able to make unintelligible sounds because of the gag. Kai then reached over and yanked on her ponytail, pulling her into a more upright position and grabbed her neck with his other hand and began choking her slightly. The reduced oxygen to the brain provided an even more pleasurable feeling. He could feel that she was getting really close to climaxing again – he decided he'd punished her enough by denying her an orgasm for so long. Releasing her neck for a second, he undid the lock on the ball gag and threw it aside and started fucking her harder. Her moans got louder as his the speed and intensity of his strokes increased.

"Kai! Oh My God you're so good at that!" Kyra grunted, her voice hoarse from the screaming.

"I'm gonna cum!" Kyra's toes curled and she moaned loud and her breathing got shorter and shallower as she climaxed, her breathing slowing down a little bit as Kai thrust into her a few more times and moaned loud as pulled out right in time for Kyra to be able to suck him off. She gave it a few sucks and deepthroated him while he came into her throat and she gave his large cock a few final licks.

Kai untied her and pulled her close to him, while he kissed her hair, she whispered to him between sharp intakes of breath, "Okay, now THAT was the greatest orgasm I ever had".
"Mine too!" Kai whispered as he leaned in to kiss her and added, "Move in with me, please". Something in Kai's beautiful grey eyes melted her heart.
"Okay, yeah, let's live together" She kissed him and then said, "You know, you really didn't punish me there, I loved every second of it".
"I know" was all Kai said.
