Rias quickly teleported us into my newly made home and when I asked for a 'large' basement to work on my flesh crafting. Rias most certainly delivered as it was a massive room the size of a football field with the roof being more than fifty meters high and I wondered if the room had spatial magic nonsense or did, they actually dug out such a huge area under the apartment complex I used to live in.
"What happened to the apartment complex I used to live in?" I asked and Rias smiled as I led the new three girls to a couple of medical benches for people to climb atop and lay down on.
"I didn't know if you were attached to anyone in the complex, so my family helped resettle them in another nearby complex with their rent and municipal bills like electricity and water being taken care of for the next five years!" Rias said proudly and my face twitched at the casual reminder of how the Gremory family has had millennia to build their wealth and were far richer than any mortal dynasty.
"I literally never spoke to my neighbors before I got drawn into your sphere of influence." I deadpanned and Rias only shrugged probably just chalking it up to do doing charity.
I shook my head clear of my random thoughts and then slapped the padded table. "Alright, girls hop on. I am going to check you for magical maladies, as well as heal any issues you may have that will hinder your potential." I spoke as Yubelluna gracefully walked over and sat on the bench I pointed out.
"Do I need to remove my dress or anything?" She asked softly and I shook my head but then cocked it to the side as I took her hands into mine and I could recognize the chemical and electrical signals shooting within her that plainly meant disappointment.
"Actually, you got a bit of lung damage from all the smoke you inhaled so excuse me," I said as I let go of her hand and my hand slipped into her wide-open dress to cup one of her large breasts.
She literally did have some lung damage so as she coughed, I fixed up her lungs and I got to play with her large breasts for a minute while I tuned up her body making its magical flow more efficient though I didn't give Yubelluna a bloodline, or anything as she hadn't earned such favor from me.
I finally tweaked her nipples making her yelp in surprise before I gave her a pat on the shoulder. "There you go. I fixed up your lungs and helped clear up your magical pathways so you will be able to channel your magic more efficiently." I explained as I helped Yubelluna stand up from the experience of being tuned up and her nerves were slightly overloaded at the moment.
"Alright you two come on up. You saw I won't bite." I joked to Ni and Li who smiled wryly as they both went to sit atop the table, and I hummed as I placed a hand on Li's bare stomach that she left bear with her low-cut sports bra she was wearing.
Li the redheaded cat girl had fairly impressive muscular development though her devil magic lagged behind as she was a fist fighter. After a moment of hesitation, I shook my head as I began to copy over the Nekoshou bloodline from Koneko and overwrite her lesser Nekomata bloodline.
"Nyah my body is feeling hot." She muttered squirming which made sense as I was greatly increasing her potential life force with her bloodline upgrade.
"Be a good girl. This is only going to make you better in all ways." I spoke as I curbed any pain she would have made with the transformation and replaced it with a strong heat and just generally made it pleasant for the girl.
"Li you got a second tail!" Ni the blue-haired cat girl called out excitedly as an extra red fur-coated tail popped up beside her other tail as she officially became a Nekoshou instead of a simple Nekomata.
"Ni lay down!" I scolded the normally more reserved blue-haired woman, and her ears went down as my pheromones had already imprinted a form of alpha sent within the animal portions of her brain.
"Yes, Master..." She grumbled as she laid down around her sister almost protectively as I worked on her but out of the corner of my eye, I saw she was already batting at her sister's two tails with a look of jealousy barely being concealed.
"Alright, Ni it's your turn. Li I got to tune up your sister so let go of my hand." I said wryly as Li was still holding my hand just below her chest.
"No, your hand is hot... It's like the heated and weighted blanket we were allowed to sleep with on our birthdays." She said dreamily and I realized maybe pampering these girls into being my loyal pets won't be that difficult at all.
I wordlessly patted Li on her head as I looked at Rias helplessly and she just rolled her eyes but still smiled with some schadenfreude. "Yeah..." She drawled off as she obviously fell into some mental remembrance before she chuckled. "Jake Koneko has a comfort blanket she won't let anyone touch under the pain of being thrown through some walls. So Goodluck getting her off you"
Listening to Rias laugh at my latest limpet that wanted to hang off me I just mentally cut off the connection I had to Li's body as I simply placed my hand in the same place on Ni while promising to give Rias an itch on her upper back that she wouldn't be able to reach.
After giving Ni the same upgrades, I then came to the conclusion that I was a fucking idiot as now both Li and Ni refused to let go of both of my hands, as they snuggled together on the padded bench. With my hands being held against their chest as they curled up into tight balls around one another.
"Ok you two can just take a nap here then," I said rolling my eyes as I tripped every chemical cocktail within their brains to send them into a deep sleep that they wouldn't wake up from for a couple hours.
Rias then coughed seeing me pull my hands free of the two catgirls and she looked to Yubelluna. "You can go retire for now. Me and your master are going to have some private leisure time in the lounge. So if we need you, we will call." She all but ordered and Yubelluna demurely nodded after glancing to me for confirmation making me subtly nod while feeling happy that she looked to me for what to do. Rather than just mindlessly obeying Rias.
