Chapter 10: The Forbidden Fruit

———

Was it the lack of sleep? Despite their intention of sleeping early, she had talked with him nearly all night long before falling asleep.

Or perhaps it was the drink she had with him before leaving? He had never had a drink before, but now that he was 16 and may drink any day when she wouldn't be around, she wanted to see him drink with her. So she shared a drink with him for the first time before leaving.

Or maybe it was both of these that caused her to lose sight of consequences, making the line between reality and dream a blur to her senses. Otherwise, why the hell would she do such a stupid thing!?

"Mhmmm~" 

Tsunade couldn't help but moan as her lovely younger brother kissed her deeply, her breasts pressing against his broad chest and one of his hands pulling her head closer while his other hand felt her soft butt.

Horrifying.

The pleasure was horrifying.

The satisfaction of the realisation that he was kissing her overshadowed the consequences she might face, the guilt she was feeling. It made her unable to think what may happen to their relationship if he kept going, if he crossed the unspoken line.

Unable to think— only for a moment.

"W-we can't!" 

Tsunade regained her senses and roughly pushed him away. She watched as he huffed, his heavy breathing a match with hers, as his gaze matched hers as well. It didn’t help that she was sitting on his lap, feeling his erection poke her behind.

"Shira… I lost my mind back then. Let's forget that ever happened, okay? L-let's continue our travel, just pretend we never stopped."

He didn't reply, just staring at her as his breathing slowly calmed down.

"16 years," he said after a while. "You have been grooming me for 16 years."

Tsunade flinched. 

"What?! G-grooming?! This is a misunderstanding, I said!"

"Right." He looked at her dryly, wiping his lips. "Sure. Let's go with that. Let's pretend this never happened and just let you go to the Marines. When you come back one day, you'll see me live happily with some other girl, maybe even Vivi. Heck, we may even lose ourselves in the bed and get a baby? Do you want a nephew or niece?"

Tsunade's expression froze as she closed her mouth, her eyes flickering with countless emotions.

"Don't do this to yourself," Hashirama sighed. "I know what feelings you have for me."

Tsunade's thinned lips parted and she looked back at him.

For a moment, she wanted to refute his claims again but…

At this point, what was the point? 

"...For how long did you know?"

"Eh… around 6 years? I mean I always thought you were joking, but at that point it was getting a bit too apparent." Hashirama said.

"Why didn't you…" she gulped, at a loss for words. "Make a move, then?"

"Perhaps because I am 16 years younger than you and would assume you'd make the first move?" He said dryly, watching her flinch again. At least the rain and the dark sky provided a sort of comforting atmosphere. 

“...”

"Yes, I just thought you'll approach me on your own when I become 'old enough', it just seemed like something you'd do."

Tsunade looked at him strangely, looking down for a few seconds before meeting his gaze again. 

"Then… what are your thoughts on this? That… I had such feelings for you?"

He didn't answer verbally. No, he jumped down from the vehicle, dropping her on the ground, under the rain, and kissed her again. This time it was short.

Tsunade's face was as red as a tomato, she knew without even looking at a mirror. Wiping her lips as he looked at her in a hungry love, she couldn't help but get wetter.

She could have him.

He wouldn't think she's a weird girl, lusting for her own brother.

Well maybe he already did think of her that way, but he was the same so they cancelled each other out.

Except… she didn't know the end result of what'd happen if she did embrace him now.

He had a bright future. A potential Queen for a wife, and therefore a Kingdom for him to rule. Should she ruin her brother's life just because of these forbidden feelings both of them shared?

Her hands trembled, and she was unable to reach a decision.

"You don't have to worry about me." Her brother said, almost as if he could read her mind.

She couldn't reply as he grabbed her waist and jumped down on the sandy ground. Now standing against him, she realised how much he had grown. She was 6"1 and he was 6"2, both tall and strong enough to pick her up and ram into her just like in her most forbidden dreams.

"It's raining," 

She said softly, pushing her face on his chest to not look in his eyes. 

"We are getting wet."

One of his feet tapped on the ground and in an instant, a huge tree appeared behind them, immediately giving them a decent cover against the rain, and Hashirama quickly pushed her back against the tree, his face just in front of hers.

However, he suddenly paused.

Conflicting emotions surfacing in his face.

For a moment, he looked deeply confused and then… sighed.

"Okay, maybe you do have to worry about me, I don't know what to do anymore." 

Her younger brother said while looking at her with a lust-filled expression. 

"I am confused now."

His hands were grabbing her shoulders, his face inches away from her. Yet, he was indirectly asking her permission to continue. If she said yes, he would probably pin her down and take her in every way she had imagined him doing her. Then, he might even insist on leaving the kingdom with her. If that happens… his friends and Vivi will be left behind.

Once again, it was her fault.

It was her who forced Vivi onto him, to make him fall for that girl.

Now, he was confused about who to choose. Confused, because of her mistake.

Despite these thoughts, Tsunade just pushed herself toward him and kissed him. She ended it quickly though, before he could grab onto her.

"You like Vivi?"

"Not enough to leave you for her."

"That means you do like her." She gave him a gentle, motherly smile. "Why don't you choose us both?"

"That-" he paused. "How are you okay with that?"

She hugged him, burying her face in his chest. "I am not 'okay' with that, dumbass." She said, "But I don't want to make your feelings conflicted, not after I was the one to initiate them. I am willing to take responsibility."

"That's dumb. You don't have to-"

"And besides," she interrupted him. "I and you alone can't revive our clan, can we? I can only give birth to so many children by myself, moreover children born from incest tend to be weird. So we can't single-handedly revive the clan. On the other hand…" she trailed off. "It's like an achievement for the boys to sleep with lots of girls right? You can have both me and Vivi, then. If she's fine with it, of course."

Honestly, she wasn't sure how she managed to say these stuff— to her brother of whom she was so possessive of, but as she said she would take responsibility, she wouldn't let him feel sad and abandon his happiness for her mistake.

Hashirama stared at her for a long moment. Droplets of rain fell from the tree leaves to trail down his hair and face and dripped down his chin.

"You know," he said, his aggressive lust calming down visibly. "You are one weird bitch." 

It wasn't the first time he called her that, he did whenever they fought, yet this time she didn't hit him for it. She couldn't, as he leaned over to kiss her again, this time it was much softer and gentle, making her smile on his mouth as she wrapped her hands around his neck, while his hands felt her perky ass with his hands.

She felt so much at peace as he felt her with his mouth and hands. It was raining, yet she was wetter than the surroundings.

"Why did you want to go to the marines while having these feelings?" He asked after ending the kiss. "Increasing distance to kill these feelings?"

She gave him an awkward smile. "Tell me for sure, you really don't have mind reading abilities?"

He smirked. "I don't need that for you." 

Then he kissed her again, this time one of his hands slipped inside her pants to rub her clit, making her gasp in sensitive pleasure as she instinctively pushed him away.

"W-wait!" she said. "Let's not go there yet, okay? It would take hours if we start… I will miss the ship."

"You still wanna go to the Marines?" He looked at her confused. "Why?"

"I didn't lie when I said I needed to fight people and all that," she shrugged, looking up at him. "They can provide good training for me.”

“Why not just become pirates? Both you and me.”

“Because as a Marine I can learn the Marine Six Techniques, and above all I can learn the pattern that they work by. With all that knowledge, when we– yes, I and you– set out to the sea as pirates, it would be too easy to avoid the marines and even if we encounter them we can use their own power and strategy against them."

"..."

"Another reason is if we set sail now, I am not sure if Vivi will come along with us. So why don't you use the time of my disappearance to hook up with her?"

"Fine, fair. But I don't want to let you go." 

Hashirama wrapped his hands around her waist.

Tsunade paused, blinking before soon she gave him an amused smile. 

"Kya~ Is my Shira so obsessed with me? I had no idea."

He frowned and kissed her again, this time it was rough— almost as if he was trying to beat her, and as his fingers slipped into her pussy despite her trying to stop it, she indeed was beaten.

“Ah- ahnn~ Stoph!”

He withdrew his mouth, almost glaring at her. 

"Sure, you can go. But… although I was the one to say it myself," he looked deep into her eyes, making her stare at him with wide, unblinking eyes. "Don't you dare get another man in the marines."

Tsunade was surprised, but above all, proud. 'Another man', he said, suggesting she already had a man. The one who was looking at her right now.

'So cute,' Tsunade couldn't help but smile. 'I really wanna eat him out right now…'

But no, not yet. She needed to hold it in.

She decided to tease him a bit. "Alas, human feelings are uncontrollable. Nobody can tell what may happen the next day."

He looked at her dryly before shrugging. "Oh well, true. Like I may just forget about you and spend my time getting wet with Vivi, instead." 

He watched her frown with a smirk. 

She grumbled at that, licking her lips she grabbed him and then spun him around, now pushing him against the tree before she kissed him roughly.

Honestly, she was trying to turn the tables, but he was too experienced while she had none. How was he so experienced??

Ugh, she didn't want to know. She just wanted to moan sweetly for him.

* * *

In his past life, Hashirama's master was a menace, even though he looked so very nice and gentle with those glowing blue eyes, snow-white hair as shiny as silver and a long beard that reached his belly. 

Hashirama would blame it upon that old man constantly making incest jokes. That’s probably why he had feelings for his own sister. Of course, Tsunade's apparent feelings for him played a role, but he had always had an open mind about such possibilities due to that old prick.

But truly, he never minded Tsunade for having these feelings. Sure, it was somewhat weird but oh well, so was he. He had done weirder things in his last life.

"At least my first kiss in this world was from her," 

He muttered under his breath as he watched his sister waving her hand from the ship that had already set sail, slowly leaving the dock. 

"I will miss her."

The ship soon vanished on the horizon and Tsunade hadn't even stopped waving then.

Hashirama was smiling, however, he suddenly flinched, almost losing his balance and falling to his knees but luckily a passerby girl caught him.

"Hey, are you alright?" The girl with straight black hair asked, looking at him in worry.

Well, he was alright. But his clone was not, it just died and he just received its memories.

Vivi was in danger.

"Shit," he cursed.

Shit, shit, shit– shit!

"Huh?"

"No, it’s nothing. Thanks for the help." 

Hashirama gave a short nod to the girl before running from the port, running fast and appearing in the forest around it. He had made the forest a few years ago, and now he felt annoyed at it because it would make him late.

Quickly backing off, he rather found an open space. Then, he put his hand on the ground and channelled his chakra to pull out a wooden construct from the ground.

A helicopter. 

One that lacked every major control needed to ride it, but that didn't matter since he would directly control it with his chakra.

People were looking at him in surprise and awe, but he ignored them all and hopped into the copter, flowing his chakra through it and then quickly flying towards Yuba, the city that had been destroyed by now.
