Enhancement!

Looking at Kurosaki's dick, Natsumi opened her mouth and she licked at her side. Feeling this, Kurosaki also started, and he inserted his tongue inside her and started to explore her walls.

The duo pleasured each other for a few hours until Natsumi was exhausted, Kurosaki picked her up in a princess carry.

"Where are you taking me? I am so exhausted right now, even my jaw is hurting because of your long dick."

"Haha! Instead of sleeping on the bed, let's sleep in the Hot Spring, so when you wake up in the morning, you will refresh." Kurosaki said as they arrived in Hot Spring and warmed the water, he entered with Natsumi, and they both enjoyed the warm bath.

"Ah! This spring really is the best~ Though, though I didn't expect you to be in the beast! Kuro, even though you had your chance, why didn't you do it?"

"Haha! It's because between your feelings and pleasure from sex, I will choose the former as I know that as long as I won't hurt your feelings, I can have sex with you anytime, right?" Kurosaki said and hearing this, Natsumi let out a beautiful smile and she said, "You really know what to say."

"Heh! Isn't that the reason why you accepted me? I know that if I hadn't pushed you at that moment, we both would have already separated and remained as strangers in each other's memory."

"Hmm! You are right, but it didn't happen. Why? It was because we both were destined, right?"

"Right," Kurosaki said as he pulled her in a hug with her back on his chest and she sat on him. Feeling his dick getting erect, she chuckled and said, "Even now, you aren't satisfied?"

"It's because my body has too much stamina and even if we did for days, I won't be satisfied. I will calm myself using chakra so that you don't have to be worried about." Kurosaki said as he calmed himself and Natsumi frowned as she heard this.

"Then what should I do?"

"Huh?"

"What should I do so that you will be fully satisfied?" Natsumi asked as she looked into his eyes and hearing this, he chuckled and said, "I don't know, maybe train? Well, you don't have to be worried about it. I will look for other ways to increase Stamina."

Natsumi nodded and then closing her eyes, she put her head on his chest and seeing this, Kurosaki kissed her forehead and said, "Good Night, Tsumi."

"Good Night, Kuro" Natsumi muttered as she heard the nickname and started to sleep with a smile on her face.

Seeing this, Kurosaki also smiled and his eyes changed to Sharingan and Senrigan.

'Ways to increase Stamina, well, first is exercise! The second is enhancing her body. Third his unlocking her Senju bloodline and then fourth would be...hmm! Let's see in past and see how Tsunade did. She could also enhance herself with Chakra.'

Kurosaki looked at the past and the lessons that Tsunade used to give. He also read the records of Stamina techniques from all the villages and then an idea appeared in his mind.

'Yeah, that should do it. For now, she will keep on exercising until I can unlock her bloodline. When her bloodline is unlocked, I will purify it and increase it's purity. Till then, she would have high Stamina, and if she wants to increase more, I just have to become strong enough to feed Isshiki to the Ten-Tails and then make a chakra fruit for her.'

'Hmm! That will do. Now apart from Fuinjutsu, and Genjutsu, I will start research on Bloodlines and the Human body.'

'My clones would be enough to work and Senrigan is enough for the knowledge. I now need capital and the best way would be to capture Ninjas that have high bounty or I will just raid the bounty place and get all the money.'

'Though I will need an assistant and with Kabuto working for Konan, I can only think of her. But, will she help me? I will just have to try and see what she wants in return for help. Though I wonder if I should tell her about Natsumi?'

'Meh! I will just talk with her later and then decide what she wants. Still, I wonder how Tsunade would react when she knows that her family member is alive, and the fact that Danzo and Hiruzen really were the ones behind her family's death.'

'With Senrigan, I can show her everything that happened in past and she will have no choice but to believe me.'

'Yeah, that's what I will do and maybe, she will also try to awaken her complete bloodline and enhance it.'

Thinking of everything, Kurosaki closed his Doujutsu and a sigh escaped his lips. He looked at his little wife's face and then closed his eyes.

The next day in the morning, Natsumi woke and found herself on the bed. Getting up, she let out a cute yawn and she looked around.

"Kuro, where are you?" She muttered while half-asleep and hearing this, Kurosaki, who was making breakfast, his eye twitched.

'Why Kuro? Why?'

"I am here!" He shouted and hearing this, Natsumi got up from the bed. She just wore a black bikini and appearing beside him, she hugged him from behind and said, "Good Morning, Kuro!"

"Good Morning Tsumi!"

After cleaning and having breakfast made by Kurosaki, Natsumi and Kurosaki appeared outside and Kurosaki thought of something and asked, "You remember the talk we had before?"

"Hm? Which one?"

"About you wanting to increase your stamina?"

"Hmm!" Natsumi said as she remembered the talk from before and a blush appeared on her face.

"I have already thought about this, and I have a plan," Kurosaki said as he pinched her cheek.

"Eh? Already?" Natsumi asked with a little shock on her face.

"Yeah, the first is to exercise and increase your stamina! It's a straightforward method, but it would take years to reach the level."

"The second would be unlocking your Senju Bloodline. Even though you will get a boost, it won't be that good as the purity of your bloodline isn't high."

"The third is part of the second, i.e., improving your bloodline and increasing it's purity. When it becomes highly pure, you will have a lot of stamina! By a lot, I mean that we can have sex for days and you won't be tired."

"As for the last one, well you won't understand, and it is a difficult one. It would take years for this, though when it is done, your stamina would reach unimaginable level and you can keep on doing for months and you won't be tired."

"What do you think?"
