Now here's the thing... This one may be based off of a particular Doujin that any cultured Honkai fan should probably know just from the words "Hot Springs". Though it's not fully bassed off or that.

Also, this was planned to drop around on Kiana's "birthday", which for K423, was set to December 7 by Siegfried. So depending on when this drops...

Happy Birthday/Belated Birthday K423 Kiana Kaslana!

Ryu x Kiana.
__________________________

__________________________

Well, today was December 7th which was the birthday of the white-haired Kaslana, Kiana Kaslana. Due to the circumstances, Theresa requested from the Overseer that Squad V took the day off to celebrate with her, and much to everyone's surprised, he approved it. So the day was littered with fun activities. First, they went out to an amusement park for a full day of fun before the plan that the others created was set.

Mei managed to get Kiana to separate from the group and go shopping with them, while Bronya, Himeko and Fu Hua returned back to the Dorm Room where they began to decorate while Ryu and Ame handled making the cake and food. In record time, they managed to prepare everything just before Mei returned with Kiana in tow and to say the white-haired Valkyrie was surprised, was an understatement. She nearly damn well kicked Ryu in the face out of instinct but just realized that no one was trying to attack her. After a bit of laughter, along with slight bickering from Ryu to Kiana, the party went on and ended on a high note.

After the party was over, Fu Hua suggested that they all should go and relax for the rest of the night at the Onsen, to which everyone agreed... Until Himeko, taking advantage of her authority, flat out forced Ryu to remain behind and clean up the after party. He was obviously upset at this but, relented. It wouldn't have mattered either way as he would have had to wait since he'd be surrounded by six naked girls...

With a look of sorry for him from the other girls, and pecks on the cheek from Bronya, Fu Hua, and Mei (to the slight jealously of Kiana), they left for the Onsen while Ryu, along with the help of his Honkai Beast, Nakith, got to work on cleaning up.

>>Small Time Skip<<

Inside the Onsen, a moan of relief came from the white-haired birthday girl as she leaned back.

Kiana: "Bwah~! Taking a dip in the Onsen after partying so hard is the best feeling ever~!"

Mei: "Hehe, so how did you enjoy the party, Kiana-Chan?"

Kiana: "It was the absolute BEST, Mei-Senpai!! It was nothing like I ever had before!"

Fu Hua: "Well, you should thank Ryu for that. He was the one who had originally had the idea of the party." She stated, standing up as she reached over for a towel.

In the meantime, Kiana was surprised to say the least. She never would have thought that Ryu would take the time to plan all of this just for her. She... was touched by it. Despite all the name calling and bickering they had with each other, he still cared to remember her birthday and plan everything.

Kiana's thoughts: "Ryu did..." She thought to herself, with her not noticing that her face had began to heat up slightly with pink hues on her cheek.

Mei: "Well, I guess I'm done for the day." She suddenly said, standing up. Her voice had startled the white-haired female who looked up at her, with a noticeable blush on her face from her thoughts.

Kiana: "Mei-Senpai, you're done already? Stay a little longer." She whined, but the dark-haired girl only giggled slightly and took up a dark colored towel.

Mei: "I want to continue reading a book. I stopped at an exciting part yesterday. And also, I want to help Ryu clean up. He done most of the work today, so it was unfair to have him be the one clean up everything." She said, sending a slight accusing glare towards Himeko, who only rose her hands up in a defensive manner.

Himeko: "He's a man. I gotta make him work his ass off."

Bronya: "Idiotka Major Himeko." She deadpanned with Ame staring at her as she stood behind Bronya, to assist her with washing her back.

Himeko: "H-Hey!"

Kiana: "Is that so..."

Mei: "Also Kiana-Chan." The white Haired girl looked at her. "Take note of the time and don't fall asleep again." She said with a smile, to which Kiana panicked a little. Every time they were to take a relaxing dip in a Onsen, Kiana, who was always the last to leave, always ended up falling asleep, which resulted in Mei or Fu Hua having to retrieve her.

Kiana: "I-I was just careless that time!"

Himeko: "If it's Kiana, she most definitely will fall asleep in the Onsen again."

Bronya: "Because it's Idiotka Kiana, it will probably happen a few times."

Ame: "Well luckily, last time Oneechan realized Kiana wasn't in her room. She found her asleep in the Onsen and carried her out. She really looked like a cooked lobster that time. One that's still alive that is..."

Kiana: "Pfft. Something that level wouldn't kill me! I can handle much more than that."

Bronya: "Uh-Huh. Well, if you fall asleep here again, The Bronya will ask Ryu to carry you back."

In an instant, the face of Kiana turned bright red as she visualized a scene where Ryu carried her naked body out of the Onsen. She imagined that he would call her all sort of sweet things before the two would indulged in some steamy activities.

Himeko: "Ara~ Someone's having dirty thoughts~" The sly tone of the red-haired instructor caused Kiana to snap out of her daydreaming and glare at them.

Kiana: "W-What!? I don't want that pervert coming in here to pick me up!"

Fu Hua: "You are terrible at lying to yourself, Kiana."

Kiana: "Hmph! Don't worry! I won't make the same mistake twice!"

Mei: "Hehe, if you say so."

Himeko: "Fu Hua, Bronya, Ame and I are leaving too. Take note and try not to fall asleep in the bath again."

Kiana: "Hai~" And with that, the other girls left the Onsen, leaving Kiana all to her own. The white-haired girl had vowed to not let herself fall asleep this time. She was going to prove them wrong this time.

10 Minutes Later...

And fall asleep did Kiana do. She had slid a bit and leaned back, with her eyes closed as she was snoring slightly. Though, a small blush was present on her face as she seemed to be dreaming, a slight whine coming from her.

Kiana: "R-Ryu...~ Not so h-hard...~"

However, a voice was heard as the door to the Onsen was opened, followed by a sigh.

???: "Ah.. Finally, I can relax in the bath... What a day..." Kiana's eyes instantly shot open as she came out of her slumber and stood up suddenly, a panicked blush on her face.

Kiana: "Wait! I'm not sleeping!!" However, she fell silent as she realized who it was. It was Ryu.

However that wasn't the biggest thing. He was without any clothes. Both of them were without any clothes as they just stared at each other, crimson blushes on their faces. An awkward silence overcame them as they just stood there, staring at each other, their eyes trailing along their nude bodies.

Kiana's thoughts: "Ryu's naked body... He's so.. muscular... And that below.. I-Is that...!" She suddenly snapped out of her train of thoughts and pointed accusingly at him. *out loud* "R-Ryu!? How dare you peep on us girls in the Onsen!?"

Ryu: "Huh!?" His eyes nearly bulged out of their sockets from the accusation. "Himeko told me that it was clear now and that I could use it now!"

Kiana: "You..." She gritted her teeth. "You took advantage to peep on a sleeping beautiful girl!?"

Ryu: "Stop spewing nonsense you damned pigheaded Idiotka! How would I even know you were sleeping IN here!? Why are you even sleeping in here in the first place!?"

Kiana: "That's not your business!" She instantly said as she got into a stance before making a mad Naruto dash towards him. "Now for peeping on me, I'll knock the memory out of you!!" She yelled but Ryu was afraid. Not of her, hell no he wasn't. He was afraid of her falling because... she's running in a hot springs.

Ryu: "Dumbass! Don't run in the-" Unfortunately it was too late, the moment Kiana stepped foot out of the water, her foot slipped and she began to tumble forwards with a scream. Ryu instantly tried to catch her, but her extreme momentum caused them both to fall over. While Groaning, the black-haired male looked at her. "Kiana... Are you alright?"

Kiana: "A-Ah.. My leg... I..." She stopped talking once she realized the position they were in.

The teens' eyes came locked with one another, their faces bright red as Kiana was lying on top of Ryu, her modest breasts pressed against his firm chest and her perky nipples rubbing against his. Their lower regions were extremely close, basically touching at this point as neither even attempted to move.

Kiana: "I-I..."

Ryu: *sigh* "Don't say it.. You just slipped and fell. I tried to catch you and boom. Let's just get up and act like nothing hap-"

Kiana: "W-Wait..." She stopped him, pressing her hands against his shoulders as her breasts slightly rubbed against him, causing her to squeak lightly, a crimson blush crossing her face. Ryu was confused and surprised. Sure, he and Kiana had a rocky on and off relationship, but she never acted like this. "Is is true... That you were the one that planned... my party..?"

Ryu: "Huh...?" He blinked in surprised, a faint blush appearing on his face. She wasn't wrong however. "Well... Technically both Mei and I were the ones doing the planning, but I did suggest it. Actually, I was thinking about it way before your birthday." The response only caused the Kaslana to blush more. Then she slowly took a deep breath.

Kiana: "W-Well... Since you went through all the trouble, a-as your girlfriend, I should reward you at least!" She said, sitting up and simply straddling him as she crossed her arms while Ryu was just bewildered.

Ryu: "You outwardly confirmed that you're my girlfriend... Did you hit your head when you fall, Tuna?"

Kiana: "S-Shut up! Be grateful that I'm considering this! Hmph!" She huffed, with her slightly wiggling her hips, causing her ass to jiggle and for her lower lips to rub against the male's member, enticing a moan from the two of them.

Ryu: "Kiana... wait-" Before he could continue, the white haired girl slid down and got off of his lap before going down on all fours and moving her head between his legs, with the black-haired teen sitting up. The moment her eyes laid on the bundle of meat before her, her eyes widened as it stood tall before her.

Kiana: "T-This is what goes inside of Mei-Senpai, Fu Hua and Bronya...? I-I forgot how big it was... W-What a beast! H-How is this supposed to even fit...?"

Ryu: "Wait, Kiana. Don't try and force yourself to do this..." He tried to deter her but she wasn't having any of it as she looked up at him.

Kiana: "But I'm not!" She declared as she slowly took hold of his shaft with her soft and smooth hands, the intoxicating smell from it increasing her blush. "Originally... Mei-Senpai was the only one my heart belonged to... then.. I fell for you and now you share that spot with her... B-But... I haven't been the best girlfriend to you.. I've only caused you more problems... That's why... I want to make it up to you!"

Ryu: "Kiana..." He muttered in.. awe. Never had he thought that the white-haired girl would take responsibility like she had now. A gentle smile appeared on her lips as she looked up at him before she looked back down at his cock.

Kiana: "And I'll do it, my way! I'll give you the full Kaslana treatment! So you better be grateful!" She suddenly said, with that normal Kaslana boasting manner that she had as she beamed a grin at him.

Before he could say anything, the white haired girl winked at him and leaned down towards the tip of his member, her body trembling from the intoxicating scent. With her slowly slicking out her tongue, she took a chance and licked the tip, enticing a soft moan from the black-haired teen. Upon seeing the reaction, Kiana knew what she was doing was right, so she continued. Her hand would jerk off Ryu's phallus as her tongue began to do laps around the tip. Her tongue slowly wrapped itself around his tip before she went down on his dick. Just the warmth along with the wetness of Kiana's mouth caused Ryu to let out moans of pleasure as she began to bob her head up and down. The only noises that could he beard in the Onsen were the extremely wet slurping and smacking noises as Kiana went to town on her boyfriend's cock, his face to scrunching up in pleasure.

A while went by and Ryu opened his mouth, his breath starting to quicken as the Kaslana's skill with her mouth was just too good. His cock began to twitch and throb excitingly, getting ready to erupt like a volcano. Ryu wanted to warn the girl, but couldn't as she suddenly quickened her pace, with her going down on him and deep throating him. She could tell that he was about to cum and wanted it to happen. Her hands gripped his balls gently, and fondled it which nearly sent him over the edge. Finally, Ryu couldn't take it anymore and let out a moan as an eruption of cum shot up from his tip and down the female's throat. Kiana's eyes widened in surprise as she didn't expect so much to be coming from the male, but she did her best to swallow every last drop. She was semi-successful but had to pull back as she coughed slightly, with some of Ryu's steaming hot cum gushing onto her breasts. Ryu sat there with a completely bewildered expression as he panted softly.

Ryu's thoughts: "W-What the heck... That skill she has... Is it a gene of all Kaslanas!?" He thought as he watched the white haired girl slowly remove the cum from her body with her tongue. Her body twitched and shivered in pleasure as she just couldn't take it anymore.

Kiana: "Ryu..~ Ah.. I can't hold back anymore..." She said. As she crawled before him, she straddled his lap and pressed her hands against his chest, pushing him back down on his back. He was about to say something, only to notice her lower regions. Her Pussy was dripping wet just from that. "I want you inside of me, Ryu... Now~..."

Taking hold of his cock, she rubbed the tip against her pussy lips, her body twitching from the pleasure as she squealed in delight before she suddenly pushed herself down on him, the sound of their skin smacking against each other as they became fully connected.

Ryu: "G-Gah, Kiana you're squeezing me tight...!" he moaned, gripping onto the female's hips firmly as her inner walls clenched around his cock tightly.

Kiana: "A-Ah, it's inside me! Ryu's hot dick is inside me~! I-It feels so good...~ I'm.. going to start moving now, okay...?"

And the love making commenced. Ryu watched as the white haired girl lustfully rode his dick, her hands planted firmly on his chest to support herself as with each wiggle of her hips, her breasts jiggled gloriously before him. The heat from the Onsen only made the pleasure that both felt even greater as the Atmosphere had become more heated with the lust that the two held for each other's body, but that wasn't all that was present.

Kiana wasn't lying when she said that she regretted how she treated him. If anyone was to look at their relationship from the outside, it didn't look healthy compared to the one Ryu had with Bronya, Mei and Fu Hua. But in truth, Kiana just had trouble fully expressing herself. But seeing how he went out of his way just for her on her special day, it made her look back on what she did for him... and from her perspective, she did very little but cause him more problems. So she wanted to make it up to him, show him that her heart belongs to him, that she loved him and everything about him.

Her pussy walls clenched around his erect phallus tightly, but her juices from her extreme arousal was enough to lubricate her enough to the point his cock was sliding in and out of her easily. Ryu was amazed. The way the girl was shaking and rocking her hips was amazing. As his hands rested on her ass that jiggled gloriously, he thrusts up into her in rhythm. Their pace began to speed up rapidly and the force behind their movements increased as the only sounds that could be heard in the area was their moaning, the wet noises of their sexes going to work and the clapping of their bodies together.

However, Kiana slowly felt herself losing control of the situation as Ryu's speed began to outmatch hers. Her eyes widened, her moans peaking at a high pitch as she felt the tip of his cock slam against the entrance to her baby making room at an alarming rate and at a strength that would put an Emperor Class Honkai Beast's punch to shame.

Kiana: "W-Wha!? W-Wait! S-Slow down a bit! D-D-Don't be so r-rough~!!" She squealed as she attempted to protest but her moans of pleasure kept interrupting her. She couldn't help but admit he felt too good. This was only their second time having sex and he was even more intense than he was before. He was on a completely different level.

Ryu: "I-It's your fault for being so damn adorable..!" He retorted with. A loud squeal from Kiana was released as the black-haired male had ended up dealing a rough spank to her ass, her buttocks jiggling from the impact. "A-Ah fuck, this pussy is amazing~.."

Kiana: "D-Don't say that~! K-Kyah~!" A surprised cry came from her, followed by a much louder moan as Ryu's hands had moved up from the girl's ass, to her well sized tits that bounced with each thrust. Clutching onto them firmly, his index fingers pressing down and rubbing against the hardened buds. "D-Don't play with them~!"

Kiana simply couldn't handle it. All of this pleasure was just overwhelming for her mind, bombarding her like the attacks from the Honkai. The way he played with her breasts and nipples, which were extremely sensitive from all of this rough play, along with the way his cock slammed into her pussy repeatedly, she couldn't take it anymore. It was just too much. Her mind was going blank.

Kiana: "I-It's t-t-too much...~! I-I...!!"

Suddenly, Ryu did something she didn't expect. Moving his left hand from one of her breasts, he trailed it down towards her snatch before stopping right at her clitoris. The white hair girl's eyes widened as he sandwiched the hardened bud between his index and middle fingers, causing her to suddenly scream in absolute ecstasy, her tongue hanging out as her walls suddenly clamped down around his cock tightly.

Kiana: "I-I'm Cumming~!"

With a moan escaping both her and Ryu and the female's back arching upwards upon impulse, the two teenagers intensely climaxed together. As her walls hugged his phallus, the Kaslana could feel her body heat radiating as she rode out her climax, while Ryu's cock tip shot multiple strings of cum into her pussy. A good minute went by as the orgasms had slowly subsided, Kiana nearly fell on top of the black-haired male below her, but managed to catch herself by using her arms to support herself.

Kiana: "S-So good...~ I-I barely can think anymore...~" Her shaky voice described as her hazy blue eyes stared into the gold ones of Ryu, who had an expression of complete astonishment.

Ryu: "I-Incredible... That was completely on a whole other level..." He muttered. Feeling movement on top of him, he looked towards the girl on him, only to see her slowly moving off of him and onto all fours before she turned around, presenting her rear end towards him.

Kiana: "Y-You came so much... You're gonna take responsibility for this, Ryu..~" She proceeded to start shaking her hips, which in turn caused her ass to jiggle gloriously before him. His eyes widened as he watched the Kaslana reach round and slowly spread her pussy lips, causing for a stream of their mixed sex juices to flow out like a river. She slowly looked back at him, giving him a lewd and dazed smile. "You can still continue, right..~?"

Ryu: "Y-You..." The only response he received from her was a wink followed by her moving her hips back and pressing her core against his hardened rod, which enticed a moan from the two off them. After a brief contemplation, Ryu decided and firmly gripped her ass. "Ah, what the heck... Who am I to deny the Birthday girl of her present~?"

The moment he finished his statement, he wasted no time and inserted his cock, the Kaslana's pussy walls remolding around his length as he pushed his way right into her. Moans of ecstasy came from the white haired girl as she threw her head back, her tongue sticking out of her mouth slightly. Due to her extreme arousal and the dripping juices from her pussy, it was extremely easy for Ryu to resume thrusting at the same fast and rougher pace as before, since he knew that Kiana did like to get quite rough. The Kaslana barely could even form sentences anymore. Her cunt was so sensitive from her previous climax, it felt as if her body was constantly on fire from each time Ryu pounded his cock into her.

Eventually, her arms gave up, causing her to fall forwards, with her ass sticking up into the air. Her drool stained the floor as her moaning only grew louder and louder from each thrust Ryu dealt. Eventually, her eyes widened as a loud *slap* echoed throughout the area from the black haired male behind her taking advantage of the position and began to spank that juicy ass of hers over and over again. At this, Kiana just lost it.

Kiana: "K-Kyah~!! N-N-Not so r-rough~! I-I'll lose my mind~!" Ryu however, took this the completely opposite direction as he grinned.

Ryu: "Hoh?" He reached down and firmly held onto both her tits before leaning back, holding her up as he began to play with the two mounds on her chest like they were his personal play things, his fingers pressing against her nipples. Just like before, Kiana's voice peaked from pleasure from the teasing to her front. "With the way your moaning, you sound like you want more~ You Kaslanas are so easy to see through~"

Kiana: "W-Wait, my b-b-breasts are really s-sensitive~!" That only encouraged him to squeeze them rougher and play with her perky buds even more than he was already was, causing her to lean back into his chest, letting her moans fill the night.

This continued without any signs of stopping. Kiana was a complete mess at this point. Her mind was completely jumbled and failing to process all of the pleasure she was constantly receiving all over her body. Ryu knew how to make her sing and singing was she doing for sure. It was a miracle that the others haven't come to check on them as of yet.

It didn't take long for Kiana to feel her climax coming rapidly again. Her already sensitive pussy was being roughly messed up, becoming a personal fuck-hole for Ryu to use to his pleasure. The way he was thrusting, he was just hitting all the right spots and the Kaslana knew that it was only a matter of time before she could come on her high again.

Kiana: "W-Wah~! I-I'm gonna..~!" She tried to state, but was cut off by her own moaning. Ryu's thrusting had suddenly ramped up, which the obvious throbbing of his phallus present inside of her.

Ryu: "S-Shit.. I'm gonna blow, Kiana~!"

Each thrust got more and more stronger as Kiana's walls began to tighten more. What she didn't expect was for him to take full advantage of the position they were in. Moving his left hand down from her left tit, he stopped right at her pussy. All it took was one rough pinch of the clitoris to completely break the white haired girl.

Kiana: "C-CUMMING~!!!"

That's all it took, as both partners went through an intense orgasm, their moaning filling the night sky. After what felt like forever, it was over, Kiana laid on the floor, panting heavily as she constantly leaked sex juices and semen from her pussy. Her body trembled greatly as her legs felt a bit numb from what just happened. Compared to the other time they had sex, this was on a whole other level.

Kiana: "A-Amazing...~ I'm... completely filled up..~" Ryu was laying down next to her on his back, his chest moving up and down from each breath he took.

Ryu: "Sorry.. I might have lost it..."

Kiana: "Hehe, don't be." The black-haired male looked at her, only to see her drag herself over to him and slowly straddle him once again, with a lustful yet... loving smile on her face. "You were just giving me my present, right~?" Ryu blinked in slight surprise, seeing the female's expression. Despised her dazed expression, he could feel the happiness radiating from her. She was being genuine with her feelings. He couldn't help but chuckle and smile, his arms snaking around her waist.

Ryu: "Heh... You could say that, Tuna." The white haired girl giggled and leaned down, pressing her forehead against his.

Kiana: "C'mon, let's do more... We have all night, after all~"

Ryu: "Man, you Kaslanas really have insane Stamina, huh?"

Kiana: "Hehe~ You underestimate us Kaslanas, Lizzard Boy~"

>>Meanwhile<<

Himeko: "Hehe, those kids out there definitely know how to have fun." She said with a sly grin as she was standing just outside of the door that led to the Onsen before she walked back into the dorm. "Now, Kiana can start being more honest with her feelings. You're welcome, you two."
