Work Text:
Senku sat down at his table and let out a long sigh. The reorganization of the former Tsukasa Empire to form the expanded Kingdom of Science had taken weeks. Building and installing various machines throughout the newly built town took a lot more of Senku’s input than he had hoped. The logistics of organizing supplies, delegating jobs, and generally reintroducing the modern people Tsukasa awakened to basic scientific advancements was stressful.
With the reorganization complete as far as he was concerned, Senku was finally done. It was time to relax before taking on the next step of their journey. He stood up to start getting ready for bed when he heard his door open behind him.
“Taiju, I told you that we’ll start working on the next project after I rest for the weekend.” Senku just wanted to be done with the day and get to bed.
“It’s me, not Taiju” a clear female voice rang out from behind him. The strength behind the voice instantly told Senku who it was. Kohaku glided through the doorway and shut the door behind her. Senku looked her up and down, the blue dress she always wore looked cleaner than usual and her hair was less wild than it was earlier in the day. She looked less like the lioness she usually was, but Senku knew it was only buried, not gone. As his eyes slid back down her exposed legs, she started fidgeting more and more.
“I’m dying to go to bed, what do you need that can’t wait until the morning?” his cynical voice broke the silence in the small one-room house. It really wasn’t the house of a chief, or maybe king now, and that was pointed out to him multiple times by Chrome and Taiju. He didn’t care about that though. All he needed was his lab and workshop built nearby and he was happy with any building with a bed his home.
“You definitely deserve more for everything you’ve done for us and even for Tsukasa’s people.” Her voice sounded less confident than before. The usually sureness that guided Kohaku’s every word and every movement was slipping away with every moment the two of them stood looking at each other. Just as Senku opened his mouth to reassert that his meager house was sufficient, Kohaku suddenly interjected “I’m not talking about this house. I’m meaning… other ways we could repay you for everything you’ve done.”
With that, Kohaku began to walk across the room towards Senku. Her steps started out slow and hesitant but gradually became more sure as she drew closer. Her head and eyes had fallen to the floor when she made her interjection, but as she neared him, she raised her eyes to meet his. Senku could see the fire burning behind her large, blue eyes betraying the wild lioness hidden behind her current appearance.
“You turned down Ruri when you became chief,” her lip trembled a bit before her instincts pushed past her nervousness and drove her to continue, “I just thought that maybe I’d offer myself to you now that you’ve become a true ruler of more than just a small village.”
Senku looked at the blushing face in front of him. He instinctively looked down to break the shared gaze. His eyes landed on her cleavage. He could tell now that it was a different dress than the one she usually wore. The top was cut deeper and the dress was shorter overall. Her cleavage was more apparent and her toned legs stood out more as his eyes traced them upward until they met the bottom of the dress. The longer his eyes explored her body, the more he felt his usually unshakeable rational mind slipping away. His eyes saw his hand leave his side and move towards her body. Seemingly by itself, his hand rose and came to rest on her hip. Her narrow waist allowed for his fingers to wrap slightly around to her back. His hand reflexively pulled her toward him. Surprised by the sudden, uncharacteristically bold move, Kohaku stumbled forward and caught herself with his body. Her arms wrapped around him as her chest pressed against his.
Their eyes locked in shock at the position they suddenly found themselves in. Both of them were already breathing heavier, their bodies pressed against each other grew warmer and warmer as they both felt as if they were starting to catch fire.
Senku’s hand slid around her body to the small of her back and he pulled her closer and he dipped his face down to meet her’s as their lips locked as they both experienced their first kiss. For a brief moment, the electricity flowing through their bodies felt like it could power the newly built town. They pulled away from each other and let out a heavy breath. The fire in Kohaku’s eyes was burning hotter than Senku had ever seen before, but tonight the fire was different. He could tell that it was fueled by passion rather than by anger or conviction. By now they were both acting on instinct as their lips locked again as they attempted to stumble towards the bed.
They separated just long enough to quickly shed their clothes before they climbed into bed together. As Kohaku laid on her back, Senku positioned himself further down the bed, between her spread legs. The fierce lioness in front of him was completely vulnerable. Every inch of her was laid before him and his eyes darted around her body. Her breasts rose and fell hypnotically as she tried to steady her breathing. They glistened with a light sheen of sweat in the dim light of the room. His eyes ventured down her body to between her spread legs. She was unexpectedly shaved down there.
“Yuzuriha helped me out a bit early so I could be ready for you… Now stop staring at me before I get too nervous.” Kohaku’s voice was soft with a slight quiver of nerves in it.
“I’m not the only one staring here.” Senku retorted, noticing that Kohaku’s eyes had been locked on his cock from the moment they stripped out of their clothes.
Kohaku managed to wrestle her eyes away from his member and locked up at him before quickly glancing away out of embarrassment. “I felt it pressing against me from the moment you pulled me against you, so it’s not my fault I keep looking at it.”
After they both laughed a bit, Kohaku took charge and grabbed Senku’s hand and guided it to her tits. They were bigger than he had imagined them in his fantasies and he eagerly started feeling her up. He ran his other hand from her thigh slowly up her body until he reached her other tit. While he continued fondling one, he pinched her other nipple and rolled it between his fingers. Kohaku’s moans echoed throughout the room as she squirmed in pleasure under him.
Senku leaned down to make out with her as he slowly slid a hand back down her body. Their kissing was quickly interrupted as a moan escaped his lips when Kohaku shot her hand down to grab his cock. Her hand worked the length of his cock with an aggressive eagerness that caught him off guard. He slid his hand the rest of the way down her body and along the inside of her thigh.
As his hand continued sliding down her body, he could feel the warmth radiating from between her legs. Another moan escaped Kohaku’s lips as his fingers brushed against her pussy. He slid his finger down to her wet pussy and teased around her opening. Sliding his finger back up, he circled her clit causing her head to jerk backwards.
Regaining her composure, Kohaku locked eyes with Senku and a smirk spread across her face. Her stroking quickened, causing Senku to shudder in pleasure. In response, he slid his finger down and slid it deep into her.
Their tongues brushed together as they continued to pleasure each other. Their lips only separating to let out soft moans.
Before long neither of them could stand to wait any longer. Kohaku pushed Senku back.
"Take me"
Her breathless desire caused Senku’s breath to catch. He repositioned himself between her legs and positioned his cock between her wet lips.
"You ready?"
"Yeah."
With a slow thrust, he pushed his cock inside of her. The pair moaned as he slid deeper and deeper inside of her. "Fuck". The room was filled with quiet curses riding on heavy breaths along with the slow, wet sounds of their passion.
Sprawled out on her back, her legs spread for the man she loved, the fierce warrior had become a slave to pleasure. She didn't mind the embarrassing sounds she heard her voice make. She didn't mind the obscene noises coming from between her legs. She only wanted him. She found herself pushing herself against him with every thrust. She wanted him deeper and deeper inside her. She wanted to feel his cock fill her up with every thrust.
Kohaku felt the pleasure building up inside her as she pushed harder and harder against his cock. Their pace quickened and her voice grew louder and louder until she screamed loudly, wrapping her legs around him to hold his cock inside of her as she came. She felt her body shake and tense in rhythm with her rapidly beating heart.
Once the waves of pleasure passed, she opened her eyes and let out a deep breath. It was her turn to make him cum.
With a smile she pushed him backwards off of her and onto his back. She climbed on top of him and positioned herself above his cock.
Senku had been mesmerized by the sight of her abs tensing and relaxing when she was climaxing. He was so caught up watching the waves of pleasure flow throughout her body that he didn't process her next movements until he was already pushed onto his back.
His eyes traveled up her body now hovering over him, lingering on her midriff and her tits, until he looked her in the eyes. Her hair was messy now and her eyes were filled with a burning passion. The lioness was back and he was certain she wouldn't give him a break until she got what she wanted.
She grabbed his cock and lowered herself onto it. Senku's hands went to her hips and helped push her down onto his cock. Through the pleasure of feeling her pussy slide down over his cock, all he could focus on was the way her tits moved as she bounced up and down on his cock.
He leaned forward and took her nipple into his mouth, sucking on it and toying with it using his teeth. Kohaku moaned through gritted teeth as she pushed herself down harder on his cock.
Leaning back down, Senku went back to using his hands on her hips to fuck her harder and harder. His thumbs dug into the inside of her thighs as he used more and more force to fuck her. He felt her pussy start to tighten around his cock more and more.
Her eyes were shut tightly and her teeth were gritted as she tried to hold off her orgasm to cum together with him. She looked down to see Senku similarly trying to hold back. She could feel his cock growing bigger and bigger as he approached climax. With the next thrust, she couldn't take it anymore. She pushed herself down one final time as she felt the waves of pleasure start to pound throughout her body. Through it all she felt his cock twitch inside her as he started to cum.
Senku felt every shot of cum being squeezed out of his cock as her pussy tightened rhythmically around his cock. He finally released the feeling that had been building and building deep into Kohaku's pussy. She stayed motionless on top of him while she struggled to stop her legs from shaking with the pleasure still pulsing through her body.
She finally managed to roll off of him and collapsed to his side on the bed. The only sounds in the room were their heavy breathing and pounding hearts as they lay recovering. Kohaku recovered first. She mustered enough strength to roll onto her side and rest her head on Senku's chest. A fresh wave of pleasure rolled through her body as she moved, feeling his cum move inside of her and start to leak out a bit.
Senku looked down at her and smiled. He planted a kiss on her forehead and wrapped an arm around her. He held her there until they both drifted off to sleep.
