Bang*!
Zenkichi lashed out a right uppercut, but Koga easily blocked them with a smile then counterattacking him with an equal force of punches he had thrown at her.
He took a step back, narrowly dodging her open palm with cold sweat perspiring his face. Taking a step forward, close up to her, and sent another uppercut to her chin... only for her to use her other hand to block his fist.
She whistled, "Damn, that's a pretty mean punch. I think it bruised my hand." She smirked, then pushed him away.
Zenkichi's steadied himself before catching his breath, his right eye twitching. "I don't see it."
Koga shrugged. "Eh, I heal fast. Also, I didn't call for a timeout—!" With a wide smile on her face, she shot towards him with a palm strike.
Zenkichi inwardly cursed as he pivoted to the side, evading her palm, only for him to receive an elbow to his side. He gritted his teeth, grabbed her arm tightly, and lashed out a kick to her side.
"Hngh! Heh, I thought you only knew how to box... ah, is it kickboxing?" Koga groaned, chuckling as she saw her stunned expression.
He wasn't given the chance to respond as she pivoted her foot to lunge an overhead punch at his face. Zenkichi barely managed to raise his arms in time to block the blow, but the force of it sent him staggering back. He grit his teeth, feeling the impact reverberate through his bones.
"Be careful. I'm going to get a bit more intense!" Koga giggled and started raining punches on him, Zenkichi was on the defensive with his arms crossed before him.
'Well, better than her palm strikes.' Zenkichi didn't understand why, but her palms somehow deals more damage to him than her punches. In a moment of carelessness earlier, he had been struck on his stomach by one of her palms and, oof, he almost vomited out his lunch.
Who even uses their palms to fight anyway?!
'This chick is crazy! Light spar my ass, no wonder she was confident. If her hands already feels being hit by a hammer, just how strong would she be if she went all out?'
Although he was sure she wouldn't actually try to kill him, Zenkichi knew he couldn't afford to let his guard down. He needed to find an opening and turn the tide of the fight.
"You're really making me work for it, huh?" Zenkichi said when he retreated back a certain distance away from her.
Koga giggled, crossing her hands over her head. "I might want a fun time, but that doesn't mean I'm easy~" She snorted and grabbed her boobs, groping them sensually. "C'mon, c'mon, Hitoyoshi-kun~ Don't you wanna touch a girl's tits for the first time~? Hm?"
"....I've touched a girl's chest before." Zenkichi retorted.
Koga paused, narrowing her eyes in doubt. "Hitoyoshi-kun. Your mom doesn't count."
"I wasn't talking about my mom!"
"Oh? Seriously? Oh my, do you have a girlfriend? My, I didn't think you were such a player, Hitoyoshi-kun~ What would your dear girlfriend think when she find out that you're hanging out with another girl?" Koga teasingly said, with a big smile and eyebrows wiggling.
Zenkichi rolled his eyes, "She isn't my girlfriend. We were young and curious is all."
"Huh? What does that...." Koga looked at hi, confused, but then she realized it. "Oh! Childhood friend is it? Ah, I know that trope. You're a lucky guy, Hitoyoshi-kun. But also a terrible person since you just think of her as a childhood friend..."
"....It's complicated."
Koga shrugged. "I don't really care. It's just as long as you're not in a relationship... are you?"
Zenkichi shook his head. "No. I'm single."
Koga smirked and pushed her chest up, making her tits jiggle. "Now that's what I like to hear! C'mon baby, come claim your prize! That is, if you can..."
Zenkichi narrowed his eyes and raised his fists, taking on the challenge.
Koga licked her lips and said, "That's it, I like a man that doesn't back down!"
There was a moment of silence as they both stared at each other, the air between them charged with tension. Zenkichi studied Koga, searching for an opening, while she continued to smirk confidently.
"Ready or not," Koga said, breaking the silence. She dashed forward, feinting a punch before spinning and aiming a roundhouse kick at Zenkichi's head.
Zenkichi ducked just in time, feeling the rush of air as her leg swept over him. He quickly retaliated with a low sweeping kick, aiming to knock her off balance. Koga jumped, avoiding his kick, and landed gracefully, her eyes gleaming with excitement.
"Nice try," she taunted, closing the distance between them with a flurry of rapid jabs. Zenkichi blocked and dodged as best as he could, but the speed and precision of her attacks were overwhelming.
Desperation fueled his next move. He stepped in close, using his shoulder to barge into her, throwing her slightly off balance. Taking advantage of the moment, he landed a solid punch to her midsection. Koga grunted, the impact making her stagger back.
"Not bad, Hitoyoshi-kun," she said, her breath slightly labored but Zenkichi could tell that she was faking it, seeing as there wasn't drop of sweat on her face. "But I'm not done yet--hmm?!"
Zenkichi knew that she wasn't done. With the knowledge that she was something like a cyborg, Koga's physical capabilities were far beyond that of a normal human. So, to overcome this gap, he had to press on the offensive!
And that was by tackling her to the ground and surmounting her with his legs on either side of her waist. He pinned her wrists to the ground, using his weight to keep her down, and pressed his lips against hers without any hesitation; even though this was his first kiss!
Well, a kiss that he initiated that is. Medaka was the first to claim his first kiss but... that was back when they were kids! Plus, Zenkichi was sure that she didn't mean anything behind it. She was that weird after all.
As Zenkichi's lips captured hers, Koga's eyes widened and her natural first instinct was to push him off. But as his tongue brushed against her lips, she shuddered and froze, unused to such an arousing feeling, making Zenkichi take the opportunity to forcibly barge his tongue into her mouth.
It was clumsy and overall very sloppy, but considering that Koga was also a virgin in having physical intimacy, she was quickly enamored by his kiss.
Although she initially came off as some sort of outgoing girl with some experience in the sex department, that wasn't true. She only came off as that to Zenkichi because she was getting desperate, her fingers and her toys wasn't enough to satisfy her anymore. It was why she had came out of her house dressed in such a slutty attire, hoping to attract some hot guy and have some fun.
It was supposed to be only some mild kisses and a promised date, it was what her little of innocence had remained thought, probably a grope or two there if she really liked the guy.
But this... Now, she didn't expect this!
'She tastes like orange,' Zenkichi thought as he moved his lips and tongue in tandem. He had zero experience, so he knew that his kissing skill wasn't gonna capture Koga's attention for long. He had just hoped that it would've been enough to surprise her so he can land a finishing move.
Scummy? Very. But that was in the case if he wasn't used to fighting a girl, Medaka used to beat his ass in elementary and middle school for training, said it was to protect him. It did help get strong and learn self defense skills, but it also screwed his mindset a bit.
But to his surprise, not only did Koga reciprocate his kiss but she was also deep into it.
'Is this also her first time or something?' He thought but the body already moved according to natural instinct. He let go of her arms, one hand held one side of her neck as he went down on the other while the second hand went down to grab her shirt.
"Hmmm~!" Koga groaned, her arms interlocking behind Zenkichi's neck as he kissed and sucked her neck. She shuddered, feeling her arousal dripping down her long legs and she knew she was close to coming-!
"Ah-! Y-You..." Koga gasped, snapping her eyes open, she whimpered with pursed lips as she looked down to see her shirt being pulled up, spilling out her huge breasts that were capped with stiff pink nipples and revealing a tone flat stomach. "Cheater." She said with pouted lips.
Zenkichi pulled his head back and smirked down at her, "Oh yeah? Do you want me to stop?" he said teasingly, flicking her right nipple playfully.
"No! Aaaah!"
But to his shock, Koga's threw her head back with a choked gasp and her hips spasmed for a few seconds before she flopped back down. Her eyes were crossed together with her lips parted, making an ahegao face.
"...Uh, Koga?" Zenkichi straightened his back as he looked at her in shock, did he just make her cum so hard that she passed out? Just by flicking her nipple? He looked at his hands in apprehension, or was it the doing of his hand? Did the Hentai System do something to him?
Just to be certain, he touched her face and gently tried waking her up. "Hey, Koga...? You alright?"
"Hm... More," Koga moaned as she blinked, her expression returned to normal for a moment before a perverted expression took over.
Her pussy was crying, the circuitry within her hummed, and her desires could no longer be held back!
She. Wants. To. Fuck! Her eyes turned slightly red, her pupils changing into heart shapes.
"Whoa, whoa. Hold it right there," Zenkichi hurriedly pinned down her shoulders with as much strength as he could muster, cursing inwardly at how much stronger she was now as she wasn't trying to hold back any longer. Her crazed eyes made him gulp. If he wasn't the reason for her arousal, he would probably be killed. "Koga, as much as I want this to continue, maybe we should do it someplace that isn't public."
Koga blinked, recalling that they were in still a park.
They were lucky that they were in a more secluded area but as time went on, cops that would usually patrol the area would see them.
As much as she wasn't ashamed to show off her body, that didn't mean that she was an exhibitionist!
"...Your place or mine?" Koga asked, mustering the most serious expression that she could. Which only came off as hilarious with the trail of drool at the corner of her lips.
"...."
A few minutes later, Zenkichi and Koga were kissing again, both completely naked, with the latter pushed up against the wall with her legs locked behind the former.
