Chaptaer 250: Kai, you really are a genius! (R-18)

--Monday, June 22, 2172

Upon hearing Nejire, Kai couldn’t hold back and started walking toward the couches while initiating a passionate kiss, to which Nejire responded with even greater fervor. When they reached the couch, Kai laid Nejire down on it without breaking the kiss, then squeezed one of her massive breasts. At that moment, the beautiful blue-haired girl spread her legs with desire.

Following the wishes of his beloved girlfriend, Kai moved his hand toward Nejire’s pussy, which was completely soaked. So much so that a thin, sticky thread formed between his finger and the tiny layer of fabric covering her special spot.

Feeling her lover’s touch, Nejire let out a moan filled with pleasure, but not forgetting her goal, she quickly looked at Kai and spoke in a breathless voice.

“Kai… I want to please you…”

“And I want to touch every inch of you to ‘mark’ you as mine.”

Kai replied in a deep, lustful tone, sending a shiver of passion through Nejire’s body. Amidst a small orgasm, she commented with shining eyes and an expression full of depraved desire.

“Sit on the couch, I’ve got an idea…”

Curious, Kai followed her instructions and sat at the end of the longest couch. At that moment, Nejire, with a look mixing curiosity and lust, unzipped his pants, revealing his erect cock. Seeing the ‘enormous monster,’ Nejire couldn’t help but swallow audibly while squeezing her thighs tightly together. But she quickly composed herself and climbed onto the couch.

After fully opening her vest and shirt, Nejire pulled down her bra to completely expose her huge breasts. She then lifted her skirt and bent down to take her lover’s cock into her mouth. With visibly inexperienced movements, Nejire began to lick it as if it were an ice cream cone while gently swaying her sensual ass, where a thin strip of fabric slid between her cheeks.

Filled with desire, Kai reached out and squeezed Nejire’s round ass, then gently pushed aside the thin, completely wet fabric covering her pussy. Visibly excited, Nejire moved sensually, and imitating some ‘educational material’ she’d borrowed from Nemuri, she took her massive breasts to ‘envelop’ her lover’s cock.

Soon, Nejire started moving her breasts up and down, trying to maintain a steady rhythm, which elicited a small moan from Kai, putting a satisfied, lustful smile on her face. But that smile quickly vanished when she felt Kai’s warm fingers caressing her delicate, wet pussy lips, forcing her to let out a vulgar moan.

Pleased with Nejire’s sensual moan, Kai grinned with lust and immediately began carefully sliding one of his fingers into her pussy, making sure not to hurt her. Feeling Kai’s finger inside her, Nejire writhed in pleasure, her back arching and her head tilting back, letting out a moan with her tongue hanging out.

“Kai… I came so hard… my legs are shaking…”

With a breathless voice, Nejire looked at Kai with an expression between orgasmic bliss and disappointment while trying to wrap her breasts around his cock again. She truly wanted to please him, but she turned out to be so sensitive to Kai’s touch that she kept cumming over and over, leaving her without the energy to continue.

For his part, Kai looked at Nejire’s legs, noticing that they were indeed trembling, almost on the verge of giving out, while the expression on her beautiful face shifted rapidly between pleasure and urgency. She seemed determined to please him before her strength completely faded.

“… Lie down.”

Feeling both touched and furiously aroused, Kai adjusted himself while guiding Nejire’s head toward him. Soon, Nejire was lying on the upper part of his abdomen, with the tip of his cock brushing softly against her tender cheek. Feeling incredibly comfortable lying there, Nejire looked at her lover’s aroused face with shining eyes and commented with a huge smile.

“Kai, you’re a genius!”

Right after speaking, Nejire turned her head to take Kai’s cock into her mouth while fully spreading her legs and lifting her skirt, exposing herself without a trace of shyness so Kai could do whatever he wanted with her.

Seeing the image of Nejire with her uniform half-off, her massive breasts exposed, and her legs wide open, revealing her wet pussy with her tiny thong pushed to the side, Kai couldn’t hold back. Quickly, he started squeezing one of her enormous breasts, so large that even his big hands couldn’t cover half of them, and moved his other hand to her defenseless, pink pussy.

As her body trembled from intense orgasms happening every few seconds, Nejire focused entirely on pleasing her Kai, using her mouth and hands to stroke his cock and balls. Though she’d never done this before, she’d secretly been asking for tips from her ‘older sisters,’ mainly Nemuri and Ryuko, though Shino had helped too.

In Shino’s case, she had given her a dildo that was a replica of Kai’s cock to practice with, so while she wasn’t an expert, she was far from clueless. She would make sure to please her Kai so he’d feel happy and as loved as she felt. After all, thanks to some ‘important research’ she’d done a while back, she discovered that sex wasn’t just pleasurable and useful for having kids.

According to her findings, sex was a fundamental part of any marriage, as it could ‘transmit love’ between partners. Therefore, since she loved her Kai so, so, so much, she had to put in maximum effort to be really good at sex and convey her endless love to him. Her research turned out to be accurate, at this moment, she felt more loved than ever.

…

After using every trick Nemuri and Ryuko had taught her, Nejire could feel Kai’s cock in her mouth starting to throb hard, the veins becoming more pronounced. A clear sign that Kai was about to cum, something her older sisters had explained to her repeatedly.

“Nejire…”

Hearing Kai’s heavy voice and feeling the increased pressure on her breasts, Nejire had another powerful orgasm, causing her pussy to tremble wildly. But keeping her focus sharp, Nejire concentrated to execute the most important step. The secret Shino had whispered to her to get Kai to show the best expression of all.

A few minutes later, Nejire felt Kai’s cock tense up completely in her mouth. Quickly, she activated her [Vital Reactor] to gain the strength to lift herself, managing to position herself just in time with her mouth on the tip of Kai’s cock.

At that moment, Nejire felt a thick, hot liquid filling her mouth, so she calmly received it until it paused for a moment. That was the most crucial instant, so with a focused expression, Nejire quickly slid her lips over the tip of Kai’s cock, not letting anything escape from her mouth. And just as she pulled away by mere millimeters, a second ‘eruption’ occurred.

Feeling the hot liquid hit her face, Nejire smiled with her lips pressed tight and subtly moved so different parts of her face would be ‘bathed’ until the ejaculation finally stopped. At that moment, Nejire felt Kai’s large, warm hand on the back of her head, while his almost hoarse, slightly guilty voice resonated in her ears.

“…Sorry, I made a mess on you.”

Following Shino’s secret advice to the letter, Nejire let herself fall onto Kai and, looking straight into his eyes, opened her mouth. She then started to ‘chew’ for a few seconds before swallowing everything in her mouth. Though it was a bit hard to swallow due to its thickness, the taste was oddly pleasant, and seeing Kai’s surprised and aroused expression, Nejire felt an unmatched thrill that made the task much easier.

“Where did you learn that…?”

Kai asked with a look full of desire. At the same time, Nejire felt Kai’s cock hardening again and brushing softly against her cheek, which put a huge smile on her face as she replied in a tired but incredibly happy voice.

“Shino taught me how!”

“…”

Seeing Nejire’s beautiful, innocent smile on her cum-covered face, with it even reaching her hair, Kai couldn’t help but swallow hard. But knowing she was exhausted and they didn’t have much time, he forced himself to calm down, reaching for a nearby table where a box of tissues flew into his hand.

“You don’t have to do it if it’s uncomfortable. I’ll talk to Shino so she doesn’t teach you weird things.”

Taking several tissues, Kai began carefully cleaning Nejire’s face while speaking in a soft voice. Nejire quickly replied with a cheerful but determined tone.

“Don’t do that, Kai-chan. I really like getting advice from the older sisters, and I really enjoyed it. I want to keep doing it in the future.”

“They’ve already corrupted my sweet Nejire…” Kai commented in a somewhat playful tone, making Nejire laugh. She then asked with a slightly mischievous smile as Kai cleaned her face.

“Did you like it?”

“I loved it.” Kai answered honestly, which practically made Nejire’s smile shine even brighter. She quickly replied in a voice mixed with joy and lust.

“Then I’ll become the most perverted girl of all. I want my Kai-chan to love me so much!”

“You don’t have to do any of that. I already love you as you are—energetic, scatterbrained, and affectionate. You don’t need to change in any way for me to love you. Just be yourself; that’s how I love you.” Kai said in a warm voice, full of care and affection. Nejire took Kai’s hand from her face, moved it aside to look into his eyes, and replied in an unusually serious tone.

“I’m not changing; I’m just learning. I want to belong to you in body and soul, just as I want you to be mine. I love you, Kai-chan; I love you so much. I want you to feel and see every part of me, and I want to see and feel all of you. So, in bed, you don’t need to take care of me or protect me. In bed, I’m your woman, the one who cums at the slightest touch from you and is willing to do anything to please you.”

Seeing the seriousness and almost obsessive light in Nejire’s eyes, Kai couldn’t help but show a small smile. Returning her gaze to his beautiful girlfriend, he commented in a confident voice.

“Don’t worry about that, Nejire. You’re already mine, and you’ll never be able to escape me.”

Seeing the almost crazed, possessive light in Kai’s eyes, Nejire couldn’t help but tremble with pleasure. As her pussy released a powerful stream of love juices while she writhed harder than ever, she took one of Kai’s hands to her exposed breast and announced in a loud, ecstatic voice full of happiness.

“Never let me escape, Kai! I’m yours, completely yours, and I’ll make sure to make you the happiest man in the world!”

“Heh, I already am.”

Kai squeezed Nejire’s erect pink nipple with his fingers, triggering another orgasm in the beautiful blue-haired girl. But instead of draining her strength, Nejire felt the orgasm fill her with energy. With a leap, she sat on Kai’s lap, then pressed one of her breasts to his lips and spoke in a voice loaded with lust and obsession.

“Mark me, Kai…”

Kai looked into Nejire’s eyes for a second, but seeing the crazed light in them, he grinned wildly and, without a word, opened his mouth, sinking his teeth around the small pink areola of his beautiful girlfriend.

Feeling Kai’s teeth pierce her soft skin, Nejire let out an almost animalistic moan while clinging tightly to her lover’s head, burying it deep into her chest. Meanwhile, her lower half seemed like a broken dam, releasing an uninterrupted stream of love juices that completely soaked Kai’s pants.

After a few seconds, Nejire felt Kai release her breast, and she fell back, supporting herself with her hands on Kai’s knees. To her surprise, she saw Kai licking his lips, slowly cleaning a crimson trail that looked like lipstick, making his lips more attractive than ever.

As her pussy released another stream of love juices, Nejire grabbed Kai’s coffee mug from the table and hurriedly rinsed her mouth with the coffee. After spitting it back into the mug, Nejire lunged to devour her lover’s lips with madness.

Soon, the kiss turned into a brutal, unrelenting battle of tongues, during which Nejire couldn’t help but greedily savor the metallic taste. Meanwhile, her lower half kept contracting, desperate to be completely filled, releasing large amounts of love juices.

After a few minutes, Nejire sat fully on Kai’s lap, then looked at her chest, where, despite a faint trace of blood, there was no wound, just a subtle mark of teeth around her areola.

“Why did you heal it?”

Nejire looked at Kai and pouted adorably. Kai laughed amusedly, then stood up, carrying Nejire like a princess, and walked toward the bathroom while speaking with a small smile.

“Because you’re mine, and I take very good care of what’s mine.”

“But I wanted it to heal slowly…”

Nejire commented in a complex tone, her heart torn between the thrill of belonging to her Kai and the loss of not having his ‘mark.’ At that moment, Kai leaned close to her ear and whispered in a voice that sounded incredibly sensual to her.

“We can always redo the mark every day so it never fades…”

“Kai, you really are a genius!”

Nejire looked at her beloved boyfriend and exclaimed, filled with genuine admiration and happiness, which made Kai laugh. He entered the bathroom while commenting amusedly.

“We’d better take a quick shower, or we’ll be late.”
