(Sorry for the late update! I'm busy at school so I can only upload chapter's when I can.)
(Gray's perspective
Rias then rushed towards me and hug me.
Even if her body is in developed stage yet, it certainly feels good being hugged by her...
''Welcome back home, Gray.'' She said to me while hugging me.
''Mhm.'' I nodded, still being hugged by her.
She then let go of me, she then asked me what I did today to the city and I answered her.
We keep walking while I keep telling my experience today.
When we arrived inside-
''Young master!'' I saw Penelope rushed towards me while shouting.
''Kuroka's little sister- Shirone woke up. Are you going to make her your maid?'' Penelope asked curiously to me.
'Yes.'
''It depends whether she agree or not.'' Though I will liked it if she agree. If she didn't, I'm gonna not gonna force her. That will give me bad points to Kuroka.
''Follow me.'' I then followed her without forgetting to say goodbye to Rias.
30 seconds later, We arrived at the medical room where Shirone is unconscious before.
I opened it and saw Kuroka and Shirone hugging each other while crying.
It's a natural reaction. I would be surprise if they didn't do that when they almost died.
Then when they heard the door opened, they were displeased about getting interrupted but when they saw us, they were not anymore.
Kuroka then stop hugging her sister and bowed to me.
''Thank you for saving me and my sisters lives.''
They were so grateful about it to me. They thought it will be their last day if I didn't save them
''Mhm.'' I nodded.
''If you wanted to thank me Kuroka, then continue being my maid.'' I said while grinning. Who would not wanted a busty seductive, hot cat maid in the future?
When Kuroka saw my perverted grin, she felt a little displeased to me ruining the wholesome moment but she don't think bad about her young master so that thought quickly disappeared. Guess her young master is really a pervert.
''I will Young master.'' Kuroka said while smiling.
'Hah.. That signal means she's going to accept being my maid.' I thought while sighing relief.
Shirone then look at her savior that is the same age as her. If she have the strength of her savior maybe they won't suffer anymore... Maybe she and her old sister will live peacefully.
She then became determined to become stronger so they won't get chased again.
While Shirone is thinking how would her life be like when she became stronger, Gray interrupted her.
''Shirone, like your older sister, I'm going to offer you the same. Be my maid.''
''The privilege are-'' Then I was interrupted by Shirone.
''I accept!'' If becoming maid means becoming stronger, she will of course accept it!
''Oooh. Someone is hasty..'' I smirked. I obviously know what is Shirone is thinking.
But I won't let her live like that, only thinking to become stronger. Kuroka will be sad if she knows it.
'Hah... I know it.' Penelope thought and sigh. Does her Young master really like maid that much? Oh well, not that she hated it. But she hope that her young master don't get too much maids because he might forget her.
When Penelope thought that, she shake her head. She have no right to complain to her young master.
''Rest well Shirone, tomorrow will be the start of your training and you two too.''
I said before I opened the door and go to my sister's bedroom. It's nighttime so I'm going to sleep with her.
I arrived at her door and open it. She saw me and started to undress her purple pajama to her red and white bra. She lays down to the bed and smiled at me.
''Let's sleep now, Gray.'' I of course change my clothes into pajamas and lay down to the bed.
''Umm Gray, does your... that thing hurt again?'' Rias asked while becoming red. Why did she asked this to him!
Hmm? Does she like doing that too me? Well I won't decline so.
''Yes, sister.'' I nodded.
Rias then came closer to me and lower down to lower my pajama pants...
She opened her small mouth and...
....
(Sorry no semi lemon today :P)
It's early in the morning.
Rias woke up and yawned.
She then rubbed her eyes and thought the yesterday events.
She couldn't help but feel embarrassed at her wrong doings. She just couldn't help it. When she first blow job Gray, and tasted his semen. She keep thinking about it all day.
What would his little brother feel when she's taking his innocence to do those dirty things to him?
Rias feel ashamed. But before she thought stopping those taboo things to Gray,
Gray woke up and smiled
''Sister! We should keep doing those things every night, it felt good!'' Gray said innocently while shouting.
Rias couldn't help but be tempted... Should she keep doing it? Her little brother even liked it so there's nothing wrong, right?... Her answer is,
''Okay.'' Rias smiled to Gray.
Then they properly dressed up and go down upstairs to eat with their mother.
Venelana greeted them while they did the same.
''So Gray, you got a new maid again.'' Venelana grinned, does her son have maid fetish?
''Yes mom, It's Kuroka's little sister. Don't worry they are both talented.'' Gray said.
"Okay.'' Venelana nodded.
''What are you gonna do now, Gray?''
