The Senju Household.
Tsunade's home was a very traditional house even for her world's standards. They were one of the founding families of her village and an old aristocracy of the land of fire.
This house has been abandoned ever since she graduated as a 'Jonin', from that moment onwards, especially after Dan's death and because of the wars, Tsunade never came back here until recently, after she was appointed the fifth hokage. This gigantic manor had remained sealed and abandoned.
Traditional spring-type baths were standard during that era, but this house only had something similar to a gigantic water barrel that was over a slightly lit-up flame to heat it up on the outside of the northern-most side of the manor. It was in the open, surrounded by layers of huge bamboo murals where the sun shone in, highlighting the vapour from the hot barrel.
"Aaahh…" Ray, Azrael and Tsunade moaned in bliss upon entering the warm water, muscles soothed and cosy. Comically enough, even Katsuyu on Ray's shoulder sighed with a little towel on top of her head.
Both of Ray's hands, if not claws, clutched both of his women posessively; he had made it clear throughout the evening. Tsunade bit her lips in embarrassment and allowed his wicked hand to roam around and fondle to his heart's content, giving her a 'mini-massage' to recover from the absolute fuckery her body had been put under.
How her breasts had been bitten until he left marks, her insides rearranged, her mouth and tongue sucked to the point of dryness. She could still remember in shame how, in the middle of this onslaught, she had given in to the pleasure and called him 'master'.
While Ray evaluated the weight of Tsunade's left boob, she covered her eyes in a sort of post-nut clarity, in which she realised how utterly conquered she was. Nevertheless, she wasn't willing to take the whole blame for that.
"You played a number on me", Tsunade hissed, looking at the primary source of blame, Katsuyu, "You and I have been together since I was a kid, you really betrayed me because of this pervert?!"
Ray hissed at her shameless blame-shifting, so thoroughly conquered that she didn't dare put any blame on him.
Katsuyu looked away, refusing to stare at her master in the eye. Tsunade was her contractor, the one whose life and integrity she had to protect. But upon being given an order by the Sun God, it was like her whole will and body moved on its own like a dog wiggling its tail to a new master.
"I'm sorry, Tsunade-sama… I am unable to resist him… it won't happen again!"
"Oh, it won't?~" Ray asked Katsuyu with that piercing and seducing glare, eyes like stars. The slug didn't dare say out loud that she'd make sure to meet whatever demand he had.
Seeing that she didn't even deny it, Tsunade flared up in outrage, but a pinch in her nipple and a flare of energy made her settle down and shudder in realisation.
'H-He's in control...'
"You're mine, Tsunade. So obviously Katsuyu is mine too... you had to be punished, and she helped me discipline you. Why do you take it on her?".
Unable to retort to her master, Tsunade once again turned to Katsuyu, "You little slug…" Tsunade tried to catch her, but Katsuyu squirrelled in fear and moved to Ray's nape with speed that doesn't fit a slug.
"Ray-sama, Tsunade-sama wants to harm me".
"I'll protect you~" Ray laughed.
"I'll protect you too, Katsuyu-chan. Stop it, Tsunade, you're being childish and I'm trying to rest," Azrael chipped in with a deep glare.
Three versus one. Seeing the opposition, Tsunade twitched her tongue and calmed down while mumbling hideously in a low yet threatening tone, 'You and I, later'.
"How do you find this world, Ray-sama?" The slug tried to make some conversation to take the moo away from her shameless betrayal; nevertheless, Tsunade wasn't finished.
"Forget that. How could you create a body for yourself, Katsuyu?" She referred to the slimy body Katsuyu had used before.
"I did so by studying Solution-san's complexion, Tsunade-sama. During our time in the other world, to help better, I needed to increase my capabilities. While feeding from Ray-sama's sun energy, my cognitive capabilities increased, and I was able to develop this slime body. Although sadly I am unable to create many since my energy intake right now is nonexistent, I'm currently working with reserves".
"You appeared without being summoned. I didn't think that was possible," She commented.
"It's all because of Ray-sama's energy. I have been trying to experiment and step out of my boundaries, but I am running out and will soon have to return to Shikkotsu. If only I could access that boundless energy again..." She stared at Ray longingly, but the latter was in a daze, about to doze off. Too much sex and too much peace were taking their toll on him.
Tsunade nudged his side lightly, partly because she didn't want him to fall asleep yet; it was too early.
"You blockhead, aren't you hearing her?"
"Huh? Eh?"
Tsunade sighed and switched her position, resting her whole body against him. This little change of position was akin to yanking Ray out of the dreamland.
"Form a contract with Katsuyu. The contract will allow you to summon her, and in exchange, she can get your energy…you spent too long with her, my energy is likely unable to satisfy her anymore, you'd better take responsibility for that" Tsunade smiled, using her index finger to run circles on his chest, reshaping the sun tattoo on his abdomen.
Ray didn't pay much attention to what she said and instead his hand slowly reached out to fondle those huge tits again. Tsunade saw it coming and smirked, making some distance with a swift move that placed her on the opposite side of the barrel.
Ray pouted.
"So?~" She reiterated.
"Katsuyu helped me so much back in the other world. If it wasn't for her, we wouldn't have been able to free all the slaves" He picked Katsuyu up and caressed his head against hers, "Of course, I will make a contract with you, darling... what do I have to do?".
The slug melted with the briefest touch, "I will serve you forever, Ray-shama~"
"Who is your master, Katsuyu...? me or Tsunade?~".
"Ray-shama, I love Ray-shama~".
"HEY!! YOU LITTLE BITCH!".
Tsunade couldn't believe it, going out of her way to help Katsuyu, only to be betrayed again. The slug realised in shock that her lips had once again moved on their own, she avoided her master's gaze in shame, "I am sorry, Tsunade-sama... it won't happen again".
If one looked close enough, her lips had curled just slightly.
"YOU SAID THAT TWO MINUTES AGO!".
"I am so sorry... I really can't resist him, Tsunade-sama".
"Come here, darling~".
With Azrael deep in the dreamworld, Katsuyu talked to Ray about how they could form their contract. It all began with a scroll where both sides would come to their mutual agreement. Usually, Katsuyu would test her recipient to know if they were worthy of her, making a contract of equals.
That's usually... but Tsunade saw, aghast, how Katsuyu had no qualms in saying she'd be delighted to be in a slave contract with Ray. It took Tsunade months of training and constant failure to be accepted by Katsuyu and form a contract back then.
The Sannin felt like crying.
She had to provide the scroll; she had to make inscriptions in Ray's body with ink, preferably his hand, from which he'd use the seals to summon her.
"Because of how abundant your energy is, it is not necessary to perform hand signs to summon me, Ray-sama. As long as you call me, I should be able to come".
Ray thought about it, having Katsuyu would definitely be useful, but he thought there was someone else he wished had access to her even more than him.
'But that may be a problem since they're in different worlds'he thought, but still decided to give it a try, since Katsuyu is so smart, she'd more than likely be able to come up with a solution.
"Hmn, I have a request for you, Katsuyu".
"Please say, I will do anything you wish, Ray-sama".
"You see, do you remember Hannah?".
"Your little bunny?~".
"Hmn", He nodded, "Could you form a contract with her as well? Hannah is still trying to adapt herself to society after what she went through, and even though she's hanging out with Rias and the others, I'd like it more if she had a more mature teaching voice like yours to guide her".
"..." Tsunade frowned. She hadn't directly met with Hannah, but she knew the girl's story from their usual interactions in the group. The girl had been a slave who suffered a lot. Eventually, Ray took her as his woman and decided to take responsibility for her.
Tsunade had vehemently refused this, but hadn't voiced it out. Recalling her own past and how she was saved, she didn't think she had the right to deny Hannah that happiness.
Seeing how Ray thought about her even now warmed her heart immensely.
Certainly, he hadn't been thinking of just playing with the bunny... he wholeheartedly wanted to help the girl recover emotionally.
'I am not the only one he has saved...'
Thinking back to her jealousy, she wondered... all of the women around him, was it just lust? Are we all his playthings...?
'No, we are not... we all have a reason to be here... even Grayfia'.
"It may be a bit difficult, but it is not impossible. A copy of mine can travel there, although I will completely lose contact with her. It is the same method I was hoping to use with you. Even if we form a contract here, once you leave this world, you will be out of my reach, Ray-sama".
The slug caressed her new master's head longingly.
"The only way is for me to send a copy of myself and re-create a main body in another world. We would be the same but different at the same time. While I am here, that version of me will have the blessing of serving you. Don't you think it is a little heartbreaking?".
"I am sorry, Katsuyu..."
He understood well enough what she meant and what she'd have to go through.
"It's okay, Ray-sama. For you... I will do even that~".
Katsuyu explained that in reality, she could always send a clone of her across worlds every so often to make sure both of her main bodies were 'up to date'.
And just like that, Katsuyu promised that she'd henceforth serve him and Hannah just as he wished. She puffed, and instead of the slug, there was a scroll.
Tsunade took it, read the contents of the scroll and sighed. She stared at Ray straight in the eye.
"Once you're back in the moonlight mist, you can use this scroll to perform the contract. You will be her first and only contractor, so she will be feeding off your energy to re-create her main body. She will be completely dependent on you in the early stages. You can do this, can't you?".
Her voice expressed urgency. In order to create this scroll, Katsuyu had to sacrifice a lot; it wasn't as simple as just creating a clone. She didn't think that little slug would go that far for Ray.
"I can, trust me".
Ray took the scroll and put it on the side, eager to go back home and form his contract with Katsuyu. More than his own aid, he believed Katsuyu was exactly what Hannah needed. She may find friends in Rias, Anna-chan and their peerage, but she needed an adult voice... a mother of sorts to guide her.
"You even took Katsuyu from me, huh?" Tsunade hissed, leaning back on her side of the barrel while her heart raced secretly.
"Don't be so melodramatic. You have your Katsuyu and I have mine, you didn't lose her".
"Hmph, I have already shared so much of myself with you. When do you even plan to marry me?".
!!!
Initially he thought she had been joking, adding a bit of comedy to her tone, but upon crossing eyes with her, he noticed Tsunade's anxiety masked in fake calmness.
'Aren't you going to marry me?'.
The question was on the table, compelling him to take action.
"I..."
