After following Saitama-sensei's training method from One Punch Man diligently, Ryosuke had successfully improved his physical stats.
At noon, he took a quick shower, ate lunch, got some rest, and after waking up, headed over to Kurenai's house.
Kurenai didn't expect Ryosuke to arrive in the afternoon—she thought he'd come at night. She had already planned for him to stay over.
Still, this was a pleasant surprise for her, so she didn't mind.
Once Ryosuke arrived, he wasn't in a rush. Instead, he spent time with Kurenai, going out shopping and having dinner together.
By the time night fell, the two returned to Kurenai's home.
Naturally, her mother wasn't around.
At that moment, Kurenai looked at Ryosuke with a shy expression.
"Give me a moment, I want to take a quick shower first."
Ryosuke nodded, happy to wait.
With a smile on her face, Kurenai headed into the bathroom. She didn't want her body to have any dirt that might make Ryosuke uncomfortable.
She showered for about half an hour before finally coming out—wearing just a pair of small shorts and wrapped in a bath towel.
She knew this look would capture Ryosuke's full attention.
Her cheeks were flushed, and steam rose from her skin as she looked at him.
"Ryosuke, I'm done washing."
Seeing her fair skin tinged with red, and the round curves tightly wrapped in the towel, Ryosuke felt an intense wave of stimulation. He was stunned for a moment.
She looked absolutely delicious—but he still held himself back.
After all, she was presenting herself so cleanly and sincerely to him, so he needed to respond with respect.
He couldn't help but walk over to her.
"Kurenai, could you hand me a towel too?"
"I'd like to take a proper bath."
Kurenai was already embarrassed enough showing up in front of Ryosuke like this.
Even though they had already been very intimate, this time she was practically laying herself bare.
She didn't expect him to be able to restrain his desire, and that gave her a strong sense of safety.
She pulled out a fresh, unused towel from the drawer and handed it to Ryosuke with one hand.
At that moment, Kurenai was holding her towel in place with just one hand.
Because of that, most of her round curves were exposed to view.
Ryosuke was having a hard time holding back the urge to play with those soft mounds.
But he still managed to restrain himself. He quickly grabbed the towel from her and walked toward the bathroom, determined to wash up as fast as possible.
He spent just two minutes inside.
All he really needed was to rinse off the dust on his body.
Wrapping himself in a towel, he walked back toward Kurenai.
Kurenai saw Ryosuke's bare upper body, and her heart stirred with excitement—his physique looked strong and solid.
Ryosuke gently lifted her and carried her into her bedroom, laying her softly on the bed while positioning himself over her.
Now that she was back in her own room—her private space—Kurenai felt a bit more at ease.
Looking up at the man before her, she said softly:
"Ryosuke, please… be gentle with me."
Although she deeply yearned to take the final step, she had heard that the first time could be very painful.
Ryosuke nodded with a smile, then reached over and switched off the nearby light.
He pulled off the towel wrapped around Kurenai's upper body—and then moved on top of her.
The night passed without further words.
It wasn't until noon the next day that Kurenai finally opened her eyes, her face still flushed and her expression weary.
As memories of the previous night surfaced, she couldn't help but savor them a little.
So this is what it felt like… to be with the one you love. It was unbelievably pleasurable.
Unfortunately, after doing it eight times, she couldn't take it anymore and had to beg for mercy again and again.
Thankfully, Ryosuke had stopped his conquest at that point—otherwise, she felt like she might have completely fallen apart.
As for Ryosuke, he had woken up long ago, but couldn't bring himself to part from the soft woman beside him.
Indeed, a man truly needs the comfort of a woman to feel complete.
After last night's battle, Ryosuke felt an unprecedented sense of comfort.
At the same time, he gained 0.5 units of chakra.
It wasn't until the final round that he heard the system's voice.
He hadn't expected that just one night of intimacy could grant him 0.5 chakra. If he did this more often, wouldn't he be able to gain massive amounts of chakra through the power of union between man and woman? At that rate, even rivaling the Tailed Beasts wouldn't be just a dream.
Based on the original story, Kakashi once said that Naruto's chakra was four times his own, and if Naruto didn't suppress the Nine-Tails, it would be a hundred times his.
So the Nine-Tails' chakra was likely 96 times that of Kakashi.
And that was the chakra level of the strongest Tailed Beast.
With this method, Ryosuke figured he'd never have to worry about running out of chakra again. After all, activating the Eight Gates Technique still required a large amount of chakra to sustain.
Overcome with excitement, Ryosuke couldn't help but reach out and fondle those soft mounds again.
He wondered if last night's eight rounds might've gotten Kurenai pregnant.
But even if she wasn't, a few more tries wouldn't hurt.
Given their current relationship, doing it more often definitely wouldn't be a problem—Kurenai clearly wouldn't object.
And thanks to his enhanced physique, Ryosuke had more than enough stamina for these kinds of activities.
