___________________________________________________________________________________________________________________

Many things happened in Saya Otonashi's life. Especially, with her relationship with her own sister, Diva. If she thinks about her, she would be cry. Just remember her name, her heart will be in pain. In one side, many people put their hope to Saya to stop the Chiropterans and Diva's desires, in other side, Saya doesn't want to kill Diva and she love her whatever Diva have done to her, Saya never hate Diva and she love her.

Saya was thinking about something to show her love to Diva, she never mean to hurt her, but Haji and other chevaliers never understand Saya's true feeling and Saya also know that they will refuse to help her show her love to Diva. So, she decided to do it by herself, she wanted to go to Diva's place, alone.

Before she got out from her hiding place, Solomon knew her dangerous plan and tried to stop her. "My lady, you shouldn't do that or I will inform the others!" Shout Solomon in the middle of darkness. Saya was surprised because of the shout and drop her sword. "B-but Solomon…" cried Saya,"If I don't, I would be unable to meet her, please how dangerous it is, I will be sneaking to her place, I really miss her.","But, my lady, I don't want anything to be happened to you, she's too dangerous to handle! What will happen to you if she…","I knew the risk Solomon, I knew it already, whatever the risk is, I still have my sword, and I swear to the world that I will be alright."

Solomon the nodded to Saya to instruct her that he understand."Solomon, if you can please keep it as a secret, can you bring me to her place?" Beg Saya half cried. Solomon can't do anything but to accept his mistress' desire. Then, he changed to his chiropteran form and embraces Saya's waist and started to fly.

The night air was cold, so Solomon tried to hold Saya as tight as he could. Even Saya was still wearing her dark brown leather jacket, she still freezing. But the cold air couldn't stop her desire to show her love to her beloved sister. She tried to hold the cold air as hard as she could. Her heart desire was stronger than the cold air attack.

She was relieved when they had arrived. Because Solomon is Diva's ex-chevalier, Saya trusted him to show her the way to sneak in. Without any complain, Solomon showed her a direct way to Diva's room. Without any doubt, Saya sneaked in with full of ambition until she reached a huge window and tried to look inside of it.

Diva hadn't slept yet. She was changing her favorite sailor-seifuuku clothes into a pajama. When she left the room to go to the toilet, Saya didn't waste this lucky chance and open the window slowly with careful without making any sound. When she did it, she entered the room and search for a great hiding place. While she was hiding, she saw Diva's pajama on Diva's bed. 'Diva must be returned to take her clothes' Saya's thought.

And Saya was right, Diva was back with only a towel tied on her body that only covered her breast until her knees with her sailor-seifuuku clothes that's being hold on her hand. Knowing this Saya was trying to wait and hold her ambition for a while until the right timing. When Diva put her sailor-seifuuku clothes, Saya got out directly and embrace Diva's waist until Diva got surprised with the direct and unexpected attack. Then, she whispered something in Diva's left ear,"Sister, I really miss you all this time…"

Surprised with Saya's unexpected words, Diva tried to release Saya's hands from her waist. But her hand was too strong to be released. "My sister Saya, do you want to kill me? What a coward thing to do, sneaking me up in the middle of night, or…do you want to…" Before she finished her words, Saya couldn't handle the straight and bare words that Diva had just released. Those words burn her ambitions even more, and broke her patient to fulfill her desires.

"…Diva, you are…stupid…" Cried Saya. With full of energy, she pushed Diva right into her bed, and kissed her sister with full of ambition. Then, she pull out her lips and whispered Diva, "I never meant to kill you, I really miss you." Those words made Diva chuckled, "My little sister, you never changed do you? Always like a little kid, of course I know you would never do any coward things, and you are also stupid and weak because of that! But maybe for tonight I will just enjoy your game for a while" Diva's rude words didn't make Saya become frustrated, she even happy to heard that.

"So that's it sister, you made the deed with me, even you are my enemy, even everyone hates you, but we are still a couple of twin siblings." Cried Saya again happily. Then, she begun to kiss her again while she tried to open Diva's towel. Then she stood up and sat right in Diva's hips, watching her beloved sister naked body. "Now now my sister, would you dare to greet your unborn cousins? Or you dare to kill them?" Hearing that, Saya only shook her head and starting to kiss and lick Diva's stomach softly from the top of the stomach until she reached the bottom of Diva's stomach that made Diva moan a little.

"Diva, maybe someday I will kill them, so I have to greet her right know so they know the one who will be killed them" Hearing that, Diva was only chuckling and open her legs wider. "Now my sister Saya, if you want to greet them, why don't you just do it directly from my unvirgin pussy? Just remember, this unvirginity is what your brother had done with me! I know you never believe it but it's true since I love sex so much!" Saya could only cried when she heard the fact about Riku again, but what have been done can't be changed anymore. "Riku wouldn't dare to do it, he still young and fresh, why did you push him to do it with you? You were the one who killed him!","Ara ara, just remember that Riku is inside of my body" Giggled Diva.

Saya then grabbed Diva's knees and made it wider. Then she lowered her head to smell the sweet smell of juices that came from the core. "You are already wet this much, you must be couldn't handle the sensation even more." Without any commands from Diva, Saya started to lick Diva's pussy from top to the bottom. This attack made Diva struggling and moaning even more,"Nnnhh…! You know it by yourself that I love sex, Saya. Ngh, how could I to be not enjoying it?" Knowing that, Saya was smiling and bit a bundle of flesh in Diva's pussy that made Diva screamed even more. "Diva, as you wish I will greet my cousins directly." Then, Saya kissed Diva's pussy and lick it again. Then she slipped her fingers inside of Diva's pussy and started to moving it in and out, and again Diva was moaning.

After several kisses and lick, Saya was stood up and kissed Diva's lips. Then, she licked Diva's breasts and kissed Diva's nipples, then licked the nipples and kissed it again while her left hand was still rubbing Diva's pussy. With the double attacks, Diva started to moaned again and her pussy was trembling down uncontrollable. "M-my sister, I couldn't handle it anymore!" After saying those words, Diva started to cum and screamed.

Saya couldn't stop her attacks, she even enjoyed it even more. When she almost did the climax attack, she heard a knock from the door. "My lady Diva, pardon me for the disturb, but are you alright? I heard you were screaming while I was walking through, if you excuse, please let me in." The heavy voice of Amshel was out from outside of the door. The twin sisters only look each other and Saya stopped the attacks because of Amshel's words.

"Diva, maybe next time we will be met again not in this condition" Warn Saya while she picked up her properties to go out from Diva's room. "I agreed my sister, yes…in a condition when you enjoy your final breath!" While Diva was laughing out loud and put on her pajama, Saya jumped out and asked Solomon to bring her back home. Solomon was relieved when she his love was alright and changed back to a chiropteran to bring Saya back.

Meanwhile in Diva's room, Diva only smiled while watching her sister, Saya with her betrayer, Solomon flying back to their hiding place. "Soon, we will meet again" Giggles Diva. "Pardon me my lady? Should I kill that betrayer, Solomon now?" Respond Amshel. "Yes, just kill him and bring back Saya to me!" Commanded Diva. Without any complains, Amshel open the window and changed in to a chiropteran. But the cold air made him freezing and Solomon already flew far away and the clouds prevented Amshel to track Solomon.

Amshel then gave up and returned to Diva with bare hands. "I'm sorry my lady, but…" Before he could finish it, Diva stopped him and said, "Don't worry Amshel, she has promised me that we will meet again someday." Then, Amshel left Diva's room while Diva was chuckling by herself and prepared herself to go to the bed. "It's a promise, Saya."
