Rei moaned as he felt Tsunade gently press her finger into his naked back and start to do circular movements, kneading his muscles with her medical chakra. All around were privacy seals so she could stay in her real form.

They were in their training ground 66 and watched as Konan was giving Mei lessons on Doton. The girl instantly spotted the tattoo on Konan and Tsunade and was sullen for three days straight! She had no idea what it was... only that it signified they were married. ​​

Rei smiled as he remembered that but instantly released a heated pant as he felt Tsunade's fingers push into his upper back, slowly sinking her entire palm into it. Her hand was glowing green and the chakra she pushed into him was nothing like suiton one.

It relaxed, loosened, and tensed his muscles continuously and randomly. It felt like being in a very gentle jacuzzi. Tsunade was good. Her medical knowledge certainly hel-

Rei again released a loud yelp as his eyes widened and a long pleasant sigh left his lips. Tsunade grinned as she finally found one of his pressure points. One that would make his body into warm goo.

She was straddling him, sitting on his lower back with her legs around his waist as he laid on the ground with his back bare. She was loving every second of this. She just couldn't get enough of his reactions. Of his moans. The fact that it was her that made him moan like that was driving her over the edge more than any sexual activity ever could. She was mentally getting off! It made her embarrassed! Proud of herself! Smug! Excited! Satisfied! And so much more, that her emotion-filled mind just registered it as unadulterated mental pleasure.

"Wouldn't it be better if you taught Mei Doton?" Tsunade asked offhandedly as she kneaded the muscles on his shoulders.

Rei smiled lazily, enjoying her care for a bit before answering.

"Nah... Konan is better."

"Hm? That's surprising." Tsunade admitted.

"What is?" Rei asked as he felt Tsunade's arms relocate to his upper arms and squeeze his biceps, making them loosen up.

"I always thought you were the ninjutsu expert of the team. No offense but Konan doesn't strike me as someone using anything but her paper." Tsunade hummed.

Rei smiled at that. He realized Tsunade didn't yet know.

"Konan's papers are a Kekkei Tota." He dropped a bomb that made Tsunade stop her hands for a second before they restarted their activity on the sides of his upper torso, pulling, stretching his muscles with devoted care.

Rei knew Tsunade was intently listening and waiting for him to continue so he did.

"She has Doton, Futon, and Suiton affinities." Rei elaborated. "To be honest, she is much better at Doton and Futon than me because she always uses it with her paper. She is natural at it while I am better at Suiton. She never learned Katon nor Raiton so I can't really brag that I am better at them than her." He chuckled and another moan tore from his throat as Tsunade's hands softly reached the nape of his neck, sending shivers through his spine.

"Hmm," She hummed, more interested in feeling Rei's body under herself pulse and quiver from her care than listening to Konan's prowess. "I see."

"You should, haa, probably take some lessons in D-, uhh, Doton from Kon-, oh, Konan." Rei said and had to pause several times as the intensity of her medical chakra increased at very specific places.

"Why?" Tsunade huffed, relocating, sliding her crotch on Rei's back until she sat on his posterior and her hands started to massage his lower back. She put her entire palms on his back and with a slight force, pushed upwards across his back. As she reached his shoulders, she did the same thing in reverse, pushing her palms downwards all the while her medical chakra seeped into his muscles, sending a tingling sensation down his entire back. "I am not ninjutsu-person."

"Yes," Rei admitted and moaned as he felt her fingers pleasantly dug deeper the second he said it. "but you have Doton and Suiton. You are Senju." He stopped to release another moan.

"You want me to get good at Mokuton." Tsunade finished for him in a matter of fact tone, fleetingly dragging her nails across his back, caringly scratching it while activating several pressure points.

"Yes..." Rei told her and felt her medical chakra go through his back, all the way to his heart and lungs as it gently purged any stress from them.

"I wanted to improve my Creation Rebirth." Tsunade sighed but then nodded and followed. "But fine. I will learn it." Her hands were on his hips now and she was repeatedly swapping between goading tickling and very soft scratching, slowly driving him mad from how pleasant it felt.

"You... can." Rei told her.

"How?" She hummed. She had a few ideas but if Rei knew...

"Kaguya." He breathed out as he could feel Tsunade delicately kneading his back above his shoulder blades.

"Hmm... Well, their bone creation IS a mystery but..."

"We are in Mizu no Kuni. There are a lot of them. I can get you one." Rei told her.

Tsunade bit her lips. He was proposing human experimentation. She was quite averse to it but...

Rei could feel her hands momentarily falter but then they gained resolve as their massaging intensified.

"Okay." Tsunade resolved herself. If it made her stronger, she would do it. "But please, make sure it is a man around forty. I don't want to dissect a woman, child, or elderly."

"Don't worry." He released a needy breath. "They are savages with male dominant society who still think the best sex is when a couple of them gangbang their females." Rei finished in disgust.

Tsunade pursed her lips. Now any guilt she could have felt for dissecting them left her.

"Why does nobody do anything with that?" She asked softly, pressing her fingers firmly under Rei's shoulder blades, trailing its shape.

"Because their women are no better." Rei sighed. "They are a closet society and their women grew up there. They start to get 'raped' very young, well, it sounds and looks like gangrape but really, as Mizukage explained it to me, for them it is a tradition and they are supposedly 'proud' of it."

"Do you actually believe that?" Tsunade snorted.

"I don't know... weirder things are happening than women of a certain clan thinking that the louder she protests and the more men she can handle through the night and actually get pregnant, the higher her status in the clan." Rei shrugged and actually hissed as the abrupt movement dragged Tsunade's medical chakra through his back too fast.

Shit, I almost creamed myself... He blushed.

Tsunade smirked mischievously and Rei started to know hell while being in the seventh heaven simultaneously. She started to drag her chakra quickly across his back with her fingers coursing through it and Rei had to bite his lower lip to not moan like a...

"That must be a sad life." Tsunade uncaringly hummed. By now, she was doing it just to get the conversation flowing. She didn't care anymore. But she wanted to see if Rei would manage to answer her in his current state!

Rei sent his raiton chakra to his nerve endings, dulling them slightly, making the pleasure less intense. With a relieved sigh, he almost giggled at the sullen pout of Tsunade.

"But so is being kunoichi..." Rei rolled his eyes, making Tsunade blink. Fair enough.

"I see. As we were raised to be such, they are also raised in their own beliefs."

"Yup."

"Well, then." Tsunade said and Rei thought the massage was over but then he felt Tsunade lean her upper body on him, her breasts melting into his upper back as her well-toned belly pressed to his lower back. And his world melted.

Tsunade's entire body was excluding medical chakra, making Rei moan desperately as Tsunade moaned on top of him. She felt every single sensation and due to Rei's raiton, she felt it more as she came the second her Jutsu started.

In the end, they both panted as Tsunade laid powerlessly on the top of Rei's back. For the remainder of the afternoon, they watched Mei and Konan play with Doton, unwilling to move.
