Determined Older Sister*
Gray first started and lick her sister's cave.
*Lick, Lick, Lick,*
''Mhhnn...'' Rias moaned while she tried to block her moan.
She then lick Gray's little brother's upper part like a lollipop without her teeth grinding it.
''Haah..'' Gray moaned a bit. His Older Sister is learning fast..
He then lick the little cherry on her cave.
''...!!''
''Haangghh...!!'' She reacted to it violently and moaned loudly
He then put one finger inside her cave, only the tip.
''Mnghhh...!!'' She moaned and have saliva dropping to her mouth.
''G-Gray, l-let me try to make you feel better first!'' Rias complained on how she can't make him feel better when she's getting distracted from the pleasure in her lower body!
''Okay..'' Gray said. He didn't have a problem with his woman, wanted to pleasure him.
Rias first lick it to the top until down. Then she opened her small mouth, trying to swallow it.
''Haah... Sister... Don't let your teeth touch it.'' Gray said after he felt pain in his little brother
She then pull Gray's little brother in her small mouth and apologized to Gray.
(Oh if your wondering what's Gray's size it's 5 inches in this form.)
She then tried to swallow Gray's little brother again with her small mouth.
She only swallowed half of it's length until she can't breath.
She then bobbled up and down her head and lick his little brother at the same time.
Gray moaned, his Big sister is certainly getting better every second. Is she determined to make him feel good? Gray chuckled a bit.
5 minutes later, Gray cummed in her mouth.
She tried to swallow it all this time.
*Gulp* *Gulp*
''Haah.. That's refreshing.'' Rias muttered, though Gray heard it.
''Mhmm..'' Rias moaned after Gray lick her cave again.
Gray then inserted his finger again, but just the tip so he won't break her hymen.
''Nghh...''
He kept licking her cave until she cummed.
''Gray... I think this is enough.'' Rias tiredly said.
But when she saw that Gray's little brother is still standing, she felt intimidated...
''Y-your not tired yet?'' She asked while stuttering. She is tired!
''Yes.'' Gray said nonchalantly. He can do this all day and never get tired.
''Hmm, Sister. Can I touch your breast?''
''S-sure...''
Gray's hands touch her breast without hesitation.
''Ngh...'' She moaned a bit when he's hands squish her breast
He then twisted her nipples and teased it.
''Ahnn...!'' She moaned loudly this time.
Gray then move closer and suck her breast.
''Hngh..!!'' Shen then hugged Gray tightly to her breast so she can feel more pleasure.
''Haangh..! Mhn..! Gray..!'' She then come.
''Haah... Haah...'' She is tired, She already come many times!
''Gray... Are you satisfied now?''
''No..'' He then suck her breast while rubbing her cave.
''Haangg..!''
They then played their bodies all night until Gray is satisfied. (AN: More like Gray played her all night.)
...
Rias woke up first.
She yawned and look at her sleepy brother. (Remember that Gray always fake sleep because he will have a worst nightmare.)
She then turned red after remembering what happen last night. She have so many hickeys when she looked at her body!
Well it's not noticeable because her body heals more faster than humans.
She then kissed Gray on the cheek. She wonder why they aren't kissing yet when they are doing something more embarrassing than kissing.
Gray opened his eyes after he felt Rias kissed his cheek.
He then decide to tease her a bit..
''Sister, did you feel good last night?'' He said with a smirk on his face.
Rias turned red and feel shame when her little brother asked her. She was moaning loud in front of her brother last night!
''Y-you! Stop teasing me!''
Gray smiled.
When Gray smiled, Rias felt that Gray is little different from the usual. Gray is playful but he is supposed to be childish but now, he isn't.
Gray move closer to her and kissed her lips
''..!!'' Rias is surprised and hurriedly move away
''I love you... Sister..'' Gray confessed to her.
Rias is surprised. She is happy that Gray loved her but is she the same? She only did that to him because she's getting lustful for some reason to her little brother.
''I-I can't answer that yet...'' Rias said in lower tone. Maybe her little brother's feelings will later disappeared in the future because he's still a kid! So this confession might not be serious.
''A-ah forget it.'' Gray awkwardly said. What is he saying? It's too early! He have the time in the world so he need to do it slowly. He fell in love too fast, maybe this is one of the reason why he got betrayed..
''Heheh..'' Rias chuckled a bit. Her little brother is so adorable right now when he's awkward.
''Let's take a bath now, we are too dirty!'' Rias cheerfully said.
They then got off in the bed and walk to the bathroom to take a bath.
Rias opened the door to the bathroom. She already is naked so she quickly go to the bath
*Splash*
Luckily the bath is pretty deep so she can jump to it!
''Haah... Gray! Come and jump here!''
''Sure...'' Gray then jump in front of his sister.
*Splash*
The water splash in front of her. Some of it got into her face so she rubbed her face a bit.
She then felt her something is rubbing her cave.
It's her smirking little brother.
''Umm, Gray...?'' They played all night, is he not satisfied yet!?
''There's one hour left until the dinner so..'' Gray said with an evil smile
He then move his face to sucked her breast again like he did many times last night.
''Ngh...'' And it still make her moan.
''Haah... You naughty little brother..'' She said seductively while grabbing Gray's little brother.
They then played again with their bodies for 40 minutes until they stop to take a shower to clean their body for the dinner. (They didn't have sex!)
They then wear their clothes properly and go down upstairs where their mother is waiting.
''How is the night, Rias?'' Venelana said with a smirk expression.
''..!!''
