Duel of Masters I

I ran through the door with mixed up feelings, there was a white trail in front of us before we reached another gate on the other side. Ely kept laughing right next to me like she couldn't hold herself back. 

"Should have seen your face, Ray!"

We crossed the last gate and arrived in our front yard, I threw Ely on the soft grass and got on top of her, the sun of Kyoto shining on us and yet she never stopped laughing. 

"Do you realise punishment awaits you?".

"I just got you a huge harem of angels and this is how you thank your wife?"

She talks like she didn't successfully pimp me out.

"Are you insane Ely? Those numbers are crazy..." If it was just Gabriel I wouldn't have an issue but those Great Seraphs wanted to farm me, "I don't know if I should feel excited or scared. I thought you were the jealous type..."

"Hmph, I only feel jealous towards women who want to steal my position. Why should I feel jealous of those angels? They just wish to have babies and I also wish to see what sort of stars your seed can create, there is no conflict of interests~".

She stood up and pulled me towards the house, her whole body changed swiftly into that of her Japanese self.

She turned around with a pout and told me something sternly, it was supposed to be a scold, but it ended up tensing up my crotch ligaments: "I don't care what you do with those angels but you must leave enough milk for mommy, okay?!".

"..."

I don't know why I expected anything different. We entered the house to find a unique view. Yasaka, Kuroka, Koneko, Rias and Akeno were all watching TV. I imagined Anna-chan going home with Sanae and Yuki.

Mom left us since she had matters to attend to regarding the trip to Tokyo promoted by her company, she made a call right away and moved upstairs. 

"Oh, you're here. How was it?" Rias asked me, giving only an ever-slight gaze before fixing back on the TV, they were watching anime. 

"It went well, I guess... where is Tsunade-san? actually... where is Kuu?"

"Hasshaku-sama left the moment we arrived, Ray-kun. She said she wanted to visit someplace since she hasn't been in Kyoto for a long time, she said she'd be back before the evening though" Akeno answered me. 

I scratched my head and didn't pay much attention to Kuu, that woman is all grown up. I can't stop her causing trouble.

Looking left and right, the blonde sannin was nowhere to be seen, I was worried about her. We hadn't been here in two weeks, and I wondered if she managed to know how to use the microwave.

"Tsunade is in her room, that woman... you should talk to her, Ray-sama" Yasaka's voice worried me, "Now that you're here, I will be on my way back to the shrine, it was lovely".

The kitsune walked up to me and delivered a soft peck on my cheeks, that was as much as we could do in front of the guests. 

"I love you, eagerly expecting our mating~" She whispered seducingly before waving to everyone and walking out of the room, leaving back to her shrine.

I waved her way and then started heading to the room mom assigned to Tsunade with awkward steps, trying to hide my erection. Mom told me that before coming to me, she assigned Tsunade her room and gave her some money, just in case... other than that the slug received no input whatsoever, for all we know in these two weeks she never left the house.

What could she have been doing?

I knocked on her room and waited a few seconds before entering since she didn't give me an answer, I gasped at the cheer disorder.

"The hell?"

The place was a total mess, there were what looked like scrolls all over the place, content written in all of them, some of them even piled up on a small mountain at the right corner of the room, next to the woman sitting on a chair, looking at the computer's screen and writing in another blank scroll.

"Oh, Ray... you're back!"

"What are you doing?"

I had to fly over the room because it was impossible to walk towards her without stepping on one of those scrolls. She stretched and I even heard a few bones cracking, her smile was broad and fulfilled. 

"I'm saving all of this world's medical knowledge and information to take it to my world but... it is so much, it is like it never ends!"

She was saving essays from renowned colleges, information from wikipedia and some other sources; writing it all in her scrolls summarized.

'How dedicated are you?!' I wanted to scream, this must be what a true scholar looks like. 

"T-Tsunade... you can't save everything... it is too much information" I don't know how many gigabits of information there are on the internet regarding medicine, but there is no way she's writing all that in scrolls. It would be easier to just purchase a load of books for her to take. 

"But I can't let it go to waste, this world's expertise in medicine is at least a hundred years, no... more!"

"But if it comes to that I can just go with you and purchase a bunch of encyclopedias. You don't need to write it manually. I can get it in Japanese-"

"There are fundamental differences in the writing structure between the Japanese of your world and the language of my world, Ray. Although similar, It is not the same. I have been struggling to translate it as I write it in the scrolls. You don't need to worry about me, I can do it".

Her confident smile put me at ease and I sighed, just let her do whatever she wanted. It even looks like she's enjoying herself doing it.

"I don't doubt you can..."

"It is amazing. The humans in this world didn't evolve their chakra pathways, you don't use the natural energy of this world. You don't have ninjutsu... although there seem to be mild examples of Taijutsu although they're far from completion. Hence you cover up for those flaws with technology. If I could adjust this knowledge to integrate the use of chakra, how much it could benefit the village..." She mumbled, doing another search.

I couldn't help but smile, watching this gorgeous woman and comparing her to the empty husk that entered that gate when I met her. 

"You like medicine, don't you...?" I patted her head, she yelped and looked at me with flushed cheeks but overall an irritated expression.

"Don't pat my head brat, I'm older than you!" She still didn't slap my hand away, but I was tactful enough to remove it. 

"Oops, you just look very cute when you're focused~"

She glared at me before sighing and looking back at the screen.

"Thank you".

"For what?"

She turned on her chair, hugging her knees and glaring at me deeply... I noticed she was still in the same clothes she had when she arrived, "It is because of you... I had forgotten how much I enjoyed being a medical-nin. I have lost so many things that I forgot this passion was also one of them... thanks for bringing it back, Ray".

She sounded so mature, this time it was she who stood up and patted my head. I didn't protest.

"You don't need to thank me, Tsunade... you sacrificed something valuable and I repaid it. I'm glad to see what you have become. By the way, you should probably speak with my mom, didn't you know she's a medical researcher? I believe she's working in research of terminal diseases, you two could share some knowledge".

"I-Is she?!"

"Yes, she didn't tell you?"

"No, but... I also didn't tell her I was a medical-nin, even if I told her she may not even know what that is" The slug smiled awkwardly but there was a newfound interest in her eyes.

"Then... I'll be off" I tried to leave but she held my wrist.

"Ray..."

"Hmn?"

"Lay down on the bed" She said that all too suddenly.

"Ho? for what?" I snickered.

"We have a deal and now I feel ready~ Lay down and I'll show you what a real massage is" There was so much challenge in her voice that my eyebrow twitched, her eyes too had a blazing flame of competition in them. 

"You sound very confident".

"Are you scared that I'll surpass your expectations?~"

I looked around the room and released an inadvertent belly laugh, "If you plan to start therapy in such an untidy place, then you have already failed the first subject, Tsunade. Go ahead, do your worst". 

Her countenance faltered, she noticed the truth of my words. The place was untidy and although it didn't smell bad, it did smell like ink, something not particularly appealing. Still I did move the scrolls away from the bed and lay down on it, placing my arms on my back and waiting to see what she was going to do. 

"It won't happen again... but I'll compensate it. It is important that the customer feels comfortable, right?" She trailed.

"That's right, how are you-"

!!!

It was then that I saw her garments start to fall one by one. She unbuttoned her shirt, there were no hangers beneath. She removed her calf-length trousers, there were white seductive panties beneath that I recognised belonged to my mom. 

Soon, her glorious self was on full display. I couldn't help but get hypnotised by the fall of her breasts, they were perfect like hanging grapes. She walked up to the edge of the bed and leaned down, straddling me and looking down sternly. 

"I figured you'd feel comfortable with my body... since we have already gotten acquainted".

"You're quite daring. I'm very comfortable, but... are you?" I snickered and relaxed, unashamedly ogling her swinging breasts, she blushed but didn't complain... it is not like she didn't expect me to look at her ravishing self. 

"I am comfortable, haven't you already seen everything there is to be seen? moreover... as before you don't particularly react. Am I not attractive?"

"You're very attractive. But I'm already very used to a woman's body, Tsunade".

"I figured as much... but..."

She placed her palm on my chest and closed her eyes, a small smile surged as she came in contact with my passive powers. 

"I still haven't gotten used to you, it feels so good just to touch you. I only want to open you up once and see what's inside".

"That's not very nice".

"Surgeries never are~".

Her hands trailed around my chest, my abs... her eyes closed, I laughed. 

"Is the therapy for you or me?"

"Damn brat, can't I enjoy myself a little?"

"It is not fair if you're the only one that gets to touch" I joked, I intended for it to be a joke, but it wasn't the case for her. 

"Then touch, Ray" She glared, her gaze so vivacious it left me breathless, "Touch wherever you want... just don't go overboard".

We shared deep gaze until I raised my hands to take a good feel out of her round breasts, they were so big I couldn't hold them completely.

"Uhm~ you're so predictable" She mused and I rolled my eyes. My actions increased the boldness of her movements and she started pinching. 

"Is this your top therapy?" I taunted her, not pinching her nipples but trailing and playing with them. 

"Ahn~ t-this is just the warm-up".

"Your warm-up or mine?"

"Both of us..."

My hands trailed along her waist, drawing a line with the back of my nails that made her shiver, I wasn't using my powers, but my touch was still prominent in energy. I held her big butt and clenched it, placing my thumb between the soft silk of the panties and her slim waist. 

"Remove these" I told her, my voice a bit more stern, sounding more like a command. 

She didn't do so immediately but instead took a grip on my shorts and started sliding them out, she only looked at me, and didn't say a word. I understood what she wanted, lifted my waist and she removed my shorts and underwear both in one clean swoop, taking a glance at my member and gulping. 

"For a boy, you're unnecessarily big".

"You fancy it still".

Her eyes rolled and she didn't make a comment, standing up on the bed with her foot at either side of my waist, she removed her panties and threw them aside. It was now my time to gulp at the erotic sight in front of me.

Nevertheless, that seemed to be the end of her boldness as she quickly collapsed and straddled me again, falling on my chest, panting. 

"I'll start now"

"I'm on your care, Tsunade~".
