The advantages kept coming for Solution. She had long since stopped just moaning. Her eyes rolled back and her tongue was out... it was frankly arousing to see her like this. It took me a while to realise that the source of her pleasure was not the fact that I was touching her... but the fact that she was tasting my skin as I touched her. 

[Time remaining: 00:22:31...]

After I finished my therapy her body was shining a little bit, one could tell just by eye that she looked like she was melting, still feeling the after-effects. But we had an agreement, I looked at Tsunade and she smirked and stood up from her relaxation. 

"Now, Solution... you wanted a chance, yes?".

"Ray-sama, I can please you... just leave it to me".

I stood up in front of her to see what she had in mind. This gooey slime wanted to show me a good time, but first, she'd sate her own needs. 

Solution embraced me and licked me all over, unlike before I could feel her naked body all gooey and sticky, it didn't resemble human skin anymore. 

"Sho tasty, Ray-shama~" Her words brimming with pleasure were no longer intelligible, she could feel me way more than any other customer, it was her trait as a slime. 

She saw my neutral expression and giggled, it was then that I started to feel it. She did something to her goo that changed the texture and made her pleasing to the touch as if she had taken my trait and appropriated it. 

It felt so good to touch her that I unconsciously hugged her against my body, exactly what this silly slime hoped. I didn't even notice all my body dripping with her goo.

"Can I kiss you?" She asked me, and I nodded. 

Solution's tongue went inside my mouth, I resisted the urge to gasp, her taste... if I had to look for the closest resemblance of anything I have tasted... it would be like sweet tapioca. Not only was it enjoyable to kiss her, but it was tasty too. 

Her tongue roamed around, entwined with mine and invaded me to the point my body started to shiver as if I was getting engulfed into a never-ending cluster of pleasure from all sides. 

'Is this what my customers feel?' I couldn't help but wonder. 

When her kiss finished she had zapped all of my saliva. 

"I'm so envious... to think you can have all this whenever you want~" Solution giggled, staring past me, Tsunade was standing there but she didn't say a word.

"Now, Ray-sama... come inside".

Sitting on top of the invisible platform, she spread her legs open, then she spread her lips open... I saw within her nethers a never-ending abyss. Once my cock went inside there, I didn't know what might happen. But still, I did it.

I aimed my cock into that abyss and pushed it in. And the feelings are something that words can't describe. 

Solution didn't emit a single moan, she received me in and hugged me until every inch was inside her gooey body. Inside I felt like my dick was getting massaged from all sides. 

I didn't even have to thrust in and out, just being inside... she did all the job, her innards did all the job. 

Fucking a slime is insane...

"How does it feel?" Tsunade arrived beside me, whispering in my ears. 

"It feels so fucking good... I-I don't even know..."

Solution giggled and released our embrace, leaning back until I could see the place where I was connected... I could see with my eyes her pussy twitching with my cock inside, clearly, some madness had to be going on inside there because what I was feeling should be illegal. 

Solution rubbed her belly and her white skin began to morph into a translucent black, her originally gooey form. Inside, I could see my cock getting slaughtered inside by her goo. Frank, I'm sorry. 

While my body started to heat up, Solution stared at me with a smile, the type of smile a woman puts on when she's getting what she wants. 

'I'm going to cum...' I groaned and put my hands against her waist in hopes of pushing her away, but her body was like glue that wouldn't let go. To top it off, Tsunade, for whatever damn reason... decided to start licking my ears. 

I could see Solution's core descending until the tip of my cock touched it.

"Uhm!~" For the first time since we started this, she moaned. For me, it felt like I was hitting her 'cervix' that's what I would think if her insides weren't so blatantly exposed to me. 

"Ray-sama!"

Solution held my head, our foreheads touched, she seemed to reach her limit just with my dick rubbing against her core, as for me? I just couldn't take it any longer. 

"Ugh!" I came... I came hard. To put it into perspective, with her insides exposed I managed to see for the first time how much cum I jet out when I orgasm. And it is no wonder I feel like my life is being squeezed out every time. 

There was so much... and her core sucked it all. 

"Tasty! So tasty!"

She seemingly lost control of her own morphology, and Solution's body went full-slime mode on me.

*RUMBLE!!*

...

The session finished, and I collapsed in Tsunade's embrace, she was smiling like she had seen the most enjoyable of shows, I didn't know what this woman was thinking anymore. 

"Tsunade... w-what are you up to?".

"I'm just interested in the type of lifeform she is, that's all~"

We saw the changes occurring in Solution's body... first and foremost, her energy became so tyrannical that the air around her heated up by the mere contact. Her goo changed and became blacker to the point it didn't look translucent anymore. It was pitch-black with something like silver sparkles mixed in between. Her morph went from a gigantic droplet to an animal, eventually settling in a female humanoid form with a big crown on her head. 

A monarch. 

When everything was done her skin regained its human contours, her blonde hair flowed down and she became exactly the same person on the outside. 

But she'd never be the same on the inside. 

She's not any weaker than Tsunade now and her eyes were staring at me with toxic obsession, nevertheless... I felt compelled to ask because for the first time, it was me who wanted it. 

"Solution".

"Yes, Ray-sama".

"Do you want to be my pet?".

She gasped, for a moment I thought she felt offended until she knelt down in front of me, took my palm and kissed it. 

"Ray-sama, a pet... I'm undeserving! I'm glorious enough just being your slave–"

"No" I couldn't give her such a low position from the start, Haku also started like that and crawled her way up, but... Solution is different. 

After what we just experienced... I don't think I can go on without her... I need to put my dick inside that goo at least once every so often.

"You will be my fifth pet".

"As you wish, master~"

Solution kissed my palm, and just like that... I stole one of Ains Ooal Gown's precious servants. 

Little did I know... the extent to which Solution would go to curry my favours.
