The seal for finalizing the bond was finished. Rei went all out with it and it became a full-body array that had various seal matrixes.

Quite frankly, anyone without his nature attunement talent would be killed by the seal. Without the nature energy acting as a stabilizer during the sealing, the matrixes would just mash together and clash, making for a very slow and very painful death. ​​

Well... it could be good for executions too!

Even though it would be a waste of ink...

...

Both Tsunade and Konan laid naked on the grass in Rei's dimension. Konan was calm and peaceful, completely fine with whatever Rei would do to her. Tsunade though...

"Calm down, Tsu-chan." Rei cooed at the quivering woman as his brush caressed her skin. He could see her getting wet but opted to go round and round and completely ignore that conversation for now.

"Ca-cal-calm down!?" Tsunade's shaky frightened eyes looked queasily at Rei. He was painting a killing number of seals on her body and it did NOT make her feel calm or safe! She was no master, barely knowing intermediate stuff that she had to learn for her yin seal but she was aware of how close to death she currently was!

"Shhh." Rei put his free hand on her head. Yes. It made her feel good and protected, alright. But... he was basically using only one hand and focusing on something OTHER than the deadly ink-splotches on her body! Reassured, she was not!

Rei smiled to himself. It was a good idea to do Tsunade first.

She was definitely like a child in the chair of the dentist for the first time.

After an entire hour of painting on her body Rei was finally done.

"It's finished." Rei sighed tiredly but the amusement was obvious in his eyes as Tsunade heaved a long sigh of relief. Her entire body was covered in black ink seals.

"You can move, Tsu." Rei told the unmoving woman as multiple times she had to turn around and lie on her belly. The seals were imprinted with a small katon jutsu into her skin the instant they were painted for a lesser error margin. This way, they didn't need to wait for the ink to dry.

Rei moved to Konan.

"Hey, beautiful~."

"Hey yourself..." Konan pouted. "You took an hour to do Tsunade so you could ogle and feel up her chest, right?"

Rei smiled and pinched her sullen cheek, making her look at him in exasperation.

"Of course, I did!" He shamelessly exclaimed, making Tsunade's eyes bulge at him.

"Pervert..." She mumbled quietly to herself yet... a small smile formed on her face as deep down, she was excited Rei found her desirable. She lowered her head in an attempt to hide her smile but her entire demeanor was suddenly brighter so it didn't do much.

Rei's lips twitched upwards as he leaned closer to Konan's ear.

"Good girl." He whispered and patted her head, making her body shudder just from hearing these words. To her, hearing it felt like having an orgasm and she was quite addicted to it already. There was a reason why she always repeated to Mei to be a 'good girl'.

Rei knew she did it to ease Tsunade up so he played along. He really didn't have time to ogle her. She was gorgeous, no, she was way past gorgeous. Her chest wasn't as big as it always seemed in anime but for her small size, it was quite contrasting. It didn't help that her breasts were all perked up and kept their form perfectly. As he said... he really didn't have time to peek, ahem, admire them. Honest!

Rei started painting the seals on Konan who was shamelessly shuddering and enjoying it. Tsunade was looking at the elated expression of Konan through the entire process with an open mouth in a perfect shape of 'O' since the first orgasm Konan had from it.

These two are worse than Jiraiya!... She mentally screamed but her hand snaked to her slit long ago.

An hour later, Rei finally finished as he wiped the sweat from his eyebrow. As he refocused on the normal world instead of seals, he instantly heard a hot panting and turned around in curiosity. He saw Tsunade playing with herself on the grass, her eyes glazed over and her body covered in a sheen of sweat. He could see that she was no longer 'just' wet but her inner thighs were drenched in her juices and he sweatdropped.

Who the hell is the pervert in this relationship! ... He resisted the urge to mumble it out loud as he looked at Konan and deadpanned.

She was pretty much in the same state except she was not trying to hide it and her eyes were invitingly and hungrily stare at him.

Rei sighed... but didn't resist.

For hours, Tsunade looked in awe as Rei and Konan moaned in ecstasy.

...

The trio created a natural bath. They gouged out some earth, covered the hole by two-inch-thick mokuton planks, and filled it with Katon-heated water made by Suiton Jutsu. They relaxed there, the girls laying their heads on Rei's shoulders.

Konan was mewling as her fingers danced up and down Rei's shaft underwater. It was just fleeting, not serious as both were spent but she loved touching and since Mei moved in... their activities suffered.

Rei was still giving some much-needed attention to Tsunade as his hand was snaked across her back, around her hip, and reached to her pussy. He massaged it, occasionally slipped his fingers inside as he used raiton or suiton to drive her to pleasure-induced madness. He didn't use nature energy as when he tried that for the first time, it instantly clashed with her Senju heritage and Tsunade couldn't move for ten minutes as her mind reeled from the sheer euphoria. Rei knew that using that would break her eventually, no matter how careful he was.

Despite everything, he didn't have sex with Tsunade. She didn't ask for it so he didn't push.

Both girls were still covered in the black seals and looked as if they were used by a tattoo artist for his new exhibition.

"I am, ugh, surprised this, ah, didn't make you p-put, oooh, out..." Tsunade said as he noticed him looking over her seal-filled skin while she felt his fingers inside her, pumping her folds with suiton chakra... she cummed. She thanked God that she piqued her interest in medical ninjutsu as that was the only reason she could even talk instead of curling into a ball and shivering. Long ago she numbed her nerve endings. Unfortunately or... fortunately, she couldn't decide, it didn't help half as much as she hoped.

"I am a seal master, dear. You covered in seals? It makes me horny, Tsu." He purred into her ear, making her go rigid only to loosen up a second later with a long euphoric moan.

"Weird fetishes aside," Rei withdrew his fingers from Tsunade's pussy, making her whimper and look at him pleadingly to which he chuckled. He also stopped groping Konan and instantly felt an intense stare at the back of his head but ignored it even though he felt her grip on his member tighten. They were relaxed and happy, drowning in pleasure for hours on end so now it was time to pay attention.

"Girls, I have to explain what the seals do. You can't go out looking like that." He smirked at them as they showed completely identical pouts.

Raising his hands, he ruffled their hairs simultaneously, making Tsunade curl up and sink to the water up to her nose and release bubbles from her mouth in embarrassment while Konan straightened up and proudly pushed her chest forward, enjoying the touch, shamelessly asking for more with her eyes.

Knowing he had their full attention, Rei pulled his hand away from Konan's head and the tip of his finger pressed tenderly into Konan's upper abdomen, under her chest. She giggled as it tickled her but held her body straight. Rei trailed the finger down, along with an intricate seal matrix.

"This," He circled one of the three seals in the seal matrix. "is a storage seal."

He knew Tsunade wanted to ask but he just pushed her head a bit more downwards with his hand on her head, making her mouth still underwater. She understood. No interruptions.

"It will make you capable of storing things into our dimension." Rei smiled. "Deep underground is a place that is basically the same as a storage seal. Each of us has a set space. To be honest I doubt you would actually manage to fill it all up." He shrugged helplessly as he even tried to store five lakes worth of water but it was still not full and he just gave up and released the water. "The advantage is that it is on your body so you can use it anytime without taking out a scroll. The safety through makes this storage seal be capable only STORE things and things only. The inbuilt storage seal only works for non-living objects as any storage seal. It could get dangerous otherwise. For withdrawal, there is another seal."

Storage seals were never on the body. It was dangerous. If they malfunction, they could shred the poor idiot with a space continuum. Alas, he had the advantage of having his own dimension so he could and DID just that. Even if he had to separate the storing and withdrawing function. Without any harm nor threat to his precious girls.

"Here," His fingers dragged itself to Konan's right lower belly, making her gasp and shiver from the touch. "is a self-storage seal." Rei smiled genially. "It allows you to store yourself without the need for a key entrance seal. But only yourself and each of you has a designated place where you will appear so we won't transfer into each other by some mistake. Additionally, even if you hold or hug somebody, he won't be affected nor transferred by the self-storing. Anyway," He smirked. The next part was his favorite as it basically made it utterly impossible to kill his precious girls. "it is instantaneous. Meaning... anytime you have to retreat from a fight due to whatever reason... you can just store yourself."

Tsunade's eyes widened as she realized just how bullshit that was. No longer was there a fear of being overwhelmed. She could go all in and then just 'poof' away. Her eyes glinted in depression but also gained a steely resolve and determination. She was weak. Weaker than both Konan and Rei. Her only worth was medical knowledge and even that was becoming somewhat obsolete due to the bullshit seals Rei was pulling out of his sleeve. She decided to better herself. To become S-rank not due to her medical knowledge but due to her destructibility!

Rei smiled as he saw the change in Tsunade's eyes and his finger fleetingly caressed Konan's skin as it went to the left side.

"Next is..."
