The Famous 69?

(* Mean's it's a lemon but don't have sex! ** Means Lemon sex! *** Means threesome!)

''Do you wanted to get stronger quickly, Shirone?''

''Mhm!!'' Shirone nodded excitedly. It's one of the reason why she decided to become Gray's maid.

''Young master, please.'' Kuroka bowed to Gray, signaling to give her Shirone like he did to herself too.

Gray nodded and just tap Shirone's forehead with a finger.

Shirone felt confused why her older sister have to bow for a tap in her forehead but after the tap, she felt something send in her mind?. No It's more accurate to say that after the tap, her young master send information directly in her mind. The information her young master send is like she's watching a Tv show, but every second detail in that show, she memorize it clearly.

''Woah...'' Shirone felt her mind clear up.

''Thank you for doing this, young master. I won't make sure you won't regret it!'' Shirone bowed to her young master after she realized how important that skill is being passed to her. She felt so grateful to him...

''Mhm. Make sure that I won't regret it.'' He then patted her head and played her ears for a bit. Shirone blushed in her cheek because only her lover or family can touch her ears and head.

'If he wants me to be his lover, then I won't decline it.' Shirone thought, her new young master just give her something so precious and more worth than her. So it will be bad for him if she didn't repay him with something.

''Be a good maid for me..'' Gray whispered.

'Maybe not...' (AN: I don't know I make it sound like she's disappointed...?)

''Then Shirone, train well to control your power. You can have a help from Kuroka because I gave you two a similar power. A specialty on Illusion, immense strength, and a super control on your Ki, Touki and Youjutsu.'' Gray said. He can give more but they need to experience their new strength first. Beside it's the most suitable power for them yet.

''Okay. And thank you again, Young master!'' She then bowed again to Gray and walk towards to her older sister to get a help to experience her new powers!

Kuroka bowed to Gray again and walk with her sister to her room.

Penelope and Gray is only left at the training room.

''Umm...''

''Hm?

''D-did I do great?''

Gray smiled. ''Heh, did I already tell you that you did great before? It's impossible to defeat Kuroka when she's one major rank higher than you and she's not an ordinary, she's like you. A little monster.'' Gray said while patting her head.

''Hmph! But young master, what about you? How strong are you when you can give the three of us that something make us quickly stronger?'' Penelope asked curiously.

''I don't know... I never spar to someone.'' Gray shrugged. 'In this life.' His mother might be a little oveprotective... But when Gray turned seven, he will have a teacher for battle lesson and training.

''...Wanna spar?''

''Sure...''

Then they run towards to the middle of the stage.

Penelope used [Ice Lighting Goddess] at the start.

She will not underestimate her young master when he's the reason why she got this power and form.

''I'll go first, kay?'' Gray playfully said. He then take a step and quickly dashed to Penelope. He's obviously holding back.

He then make a sword out of thin air then tried to slash Penelope with it. It's sword's appearance is just see through Gray colored sword.

Penelope tried to block it with all of her might. But when her sword clashed with Gray's, she got blown away from the shockwave. But before her body hit the wall, Gray catch her waist.

Penelope's face... Was priceless that even Gray chuckled a bit.

''Hahah... Your face... Are you that shocked?'' Gray laughed before asking Penelope

''Of course! You already have that strength at the age of 6!'' Penelope said with an serious expression. Something bad or good would happen to her young master if this news get out.

Gray chuckled, ''You don't need to worry about me. I can take care of myself.'''

''Even then, I'll still be your side.'' Penelope said with a blush on her cheek.

Gray smiled and hug Penelope.

''Then you be mine for eternity...'' Gray whispered while hugging her tightly

Penelope turned red, but still didn't run because her young master is hugging her tightly.

''Mhm..'' Penelope nodded.

Gray then kissed her cheek. (It's still to early to kiss on the lips!)

''Uwawwawa..'' Penelope became lovestruck to her young master... She's to embarrassed to say anything!

''C-can I k-kiss you to on the cheek?'' She's going to take the initiative this time!

Gray chuckled, ''Sure.''

Penelope then came closer to her Young master's cheek and...

She peck it with her lips.

And run away quickly after doing it.

It's so fast that it's like she instantly disappeared.

Gray laughed. Maybe his life this time won't be so bad at all.

Gray stop laughing and remembered that he's going to do something tonight with his Older Sister.

He then walked back to the mansion and...

...

Night time comes.

Rias is nervous today. Her little brother is going to do something shameful to her!!

She is still wearing her purple pajama while laying down in the bed.

Is her brother really innocent? Rias thought. Maybe he is just curious on doing the same on her too.

'E-enough thinking! I should be calm like a older sister to Gray!'

''Haah...'' Rias take a deep breath. Why is she nervous, isn't Gray just gonna lick her t-thing under her panties? It's nothing big, right?

While thinking, the door opened.

It's Gray.

Rias instantly became nervous, but she still ask.

''A-are we really doing 'it' today?'' Rias stuttered while asking, she is embarrassed!

''Are you nervous, Sister? If your uncomfortable doing it, then we should just sleep today.'' Gray calmly said. He's really not going to force his big sister of she's that uncomfortable doing it.

Yes, Rias is nervous, maybe little uncomfortable doing it but... Her pride as a older sister to Gray is getting broken when she's getting nervous, not Gray! She should be the one who is calm in this situation, not Gray!

''N-no, it's just I'm pretty nervous because it's my first time...''

''Hoh..? Did I just take my sister's first time?'' Gray teased.

''Y-yes you dummy!'' Rias became red, why is she reacting like this to her little brother? She wants to be in control in this situation dammit! (Rias is older sister type.)

She then take off her pajama. The bra only remains, covering her pretty modest breast. Her body gives an seductive feeling to Gray (Remember, Rias look like teenager here!)

She take then off her remaining undergarment, showing her beautiful naked body to Gray.

She then sat down in the, while opening her legs, showing her cave to Gray.

*Throb*

It's Gray's little brother, reacting to it... Well sadly for it, Gray won't do it yet.

He then kneeled down, his face is getting closer to her cave that Rias is getting nervous.

He then tried to touched it, showing to Rias he is just curious too.

When Gray's finger touch her cave's outer part, she shivered.

She is pretty nervous, but when Gray touched her, it felt good and calmed her a bit.

Rias is pretty sensitive.

So when Gray touched her more, she shivered and tried to cover her moans.

''Nnggh.. Ahn.. Ha..''

So when Gray intensify his touching, Rias cummmed and it splash to Gray's face and fingers.

''Haah.. Haah.'' Rias is pretty tired, if getting touched by him make her like this then what about his tongue?

Rias felt nervous and expectation.

Gray then licked his finger and..

''Gray! What are you doing, it's dirty!'' Rias scolded while her face is red

''Hmm. It taste like strawberry, with an bitter taste... It's great!''

''I didn't asked you how it tasted!'' Rias said, her pure little brother complimented her love juice's taste! Rias felt shame and embarrassed.

Gray then without a warning, came closer to her cave and lick it.

''...!!'' Rias is shock and shivered violently, she isn't prepared to this!

''Haahn..! Ahhnn...! Nghnn..!'' Rias is moaning loudly, she realized this and cover her mouth to muffled her moan.

''G-Gray, wai- Hngg..!''

She was quite sensitive so she cummed fast.

''Haah... Haah.. Gray!'' Rias pouted.

''Why didn't you tell me that your going to do it!'' She isn't angry but she felt embarrassed and shame when Gray is seeing her state when he licked her.

''Sorry...'' Gray said with an apologizing expression. He is not sorry because Rias liked it.

''It's fine but, just warn me later if your going to do it..''

''Hmm, Sister, my thing is getting hurt here... Should you try to lick it again?''

''Sure! But I have an idea so we can feel good at the same time!'' Rias said when she have something pop in her mind when Gray licked her.

They then lay down to the bed and change position.

Rias face is facing Gray's little brother while Gray faced Rias sensitive cave.

''Are you ready, Gray?'' Rias said with an determined look. She is determined to make her little brother feel good so her pride as an older sister will recover!

''Mhm.'' Gray nodded. 'Guess we're trying The Famous 69.' He then tried to lick his sister first.

Then...

...
