She can’t

Eve gently pushes her sister away and says, “I love you too, Ai. But you’re my sister. We just can’t.”

When Ai hears those words, she feels like she’s being stabbed in the back. How could Eve do this to her? Can’t Eve see she truly loves her?

Ai pulls away from her sister dejected and says, “I … I understand.” Then she stands up.

Eve makes a move to stand as well, but suddenly Ai tackles her. Eve falls back to the grounds and gets nearly pushes off the island by Ai. Eve tries to fight back, but she was so surprised by Ai’s unprovoked attack, she is completely unprepared. The fight ends with Eve lying face down on the beach of this little island. Her face lies on the ground just on land, and the rest of her body below the water. Above her lies her sister and she can feel Ai’s dick trapped between her ass cheeks. Also, Ai is holding Eve in place with an arm-lock.

“Ai, what are you doing?!” Eve yells at her sister.

“I’m sorry, Eve.” Ai says. “You made me do this.”

Eve then feels Ai’s dick slide down her crack and sink between her legs. A second later it is inside her pussy.

“Ai! What are you doing!?” Eve yells at her sister. “Pull that thing out!”

“Ooooh, Eve. I’m so sorry.” Ai says as she starts thrusting. “But I need to do this. I have to show you how much I love you.”

“This is not love, Ai! It’s ****!” Eve says, trying to get through to her sister. "That fruit must have messed with your head! STOP THIS!"

But Ai isn’t listening to her. She continues to fuck her big sister. With every thrust Ai makes waves in the water. It starts splashing, causing ripples that spread across the entire surface of the lake. Eve tries to pull free, but every time she makes the attempt Ai tightens the lock she has on her sister’s arm.

“Oh, Eve. I’ve been wanting to do this for so long.” Ai moans. “Ever since I saw you in the tower I’ve wanted to make love to you. Now the tower has given this, so we can truly be connected. Oh god, I love you so much.”

By now Eve has given up trying to push her off. Whatever has gotten into her sister, there is no talking her out and there is no getting out of this lock. She’ll just have to endure it until Ai is done with her. Despite how terrifying this is to her, the constant pounding she receives causes her to travel down the road of pleasure. It must be Ai’s dick that’s doing it. Eve closes her eyes and waits patiently for either Ai to cum or her own body to betray her.

As the minutes pass, Ai only fucks her more forcefully. And Eve starts to...feel different. Eve starts to enjoy this more, and more, and she can't help but moan a little.

"Coming around to the idea?" Ai asks Eve after hearing her small moan.

Eve tries to talk back to her...but she can't find the words to say no. She just can't find a way to voice her resistance, and her body keeps feeling weird as it's warming up.

"Then let's do this properly, Eveline." Ai says, as pulls out of Eve, and flips her onto her back. Most of Eve is still in the water, but now she can look Ai straight in the eyes, as Ai places both her hands on Eve's hips, and thrusts back into Eve, causing her to elicit a large moan. This time, Eve can't resist, and wraps her legs around Ai's hips, and as Ai starts thrusting into her sister, Eve starts thrusting back. Every thought in Eve's head is saying this is wrong, that she should be stopping her, that she doesn't consent to this, but every time Ai pounds into her, those thoughts get a little quieter, and Eve thrusts back a little harder. Eve keeps trying to say something between her moaning, until she finally says something.

"I should have never resisted you Ai. I was weak, I was afraid. But you were strong, you've proven that you were always the one who should have been in charge. You are my master. Please fuck me harder. Please fill me up with your seed. I'm just a little slut for your cock. You'll take care of me forever right?"

Every line Eve says isn't something she believed before she said it, but after she spoke...it's like everything she said became true. Like she suddenly believed that Ai was her master, that she was the strong one. That Eve could only count on Ai to take care of her. Eve lost her last traces of resistance, lost her traces of willpower, lost her strength, as she just felt herself submit body and mind to Ai.

And Ai smiled, as she kept thrusting into Eve faster, and harder, as Eve just kept thrusting back, moaning like the whore that she had become, loving every second of her sister's cock.

When Ai is almost there she says, “Eve. Oh Eve, I’m almost there. I love you so much, big sister. Let me show you how much in love I am with you. Let’s be together forever!”

Then Ai cums and floods Eve’s pussy with her sperm. As the dick inside her starts blasting fertile seed, Eve’s pussy starts contracting and sucks it into her womb. Eve roared with her orgasm, as she felt Ai fall onto her, caressing her body, and kissing her neck.

"Don't worry Eve, I'm the big sis now. I'll take care of you. Forever." Ai said into Eve's ear.

Then Ai mounted Eve again, eliciting more moaning from her sister, as she started thrusting into her again. "I'll take care of everything."

Outside, the top of the tower opens up, and a bright beam of light bursts outside the top of the tower. The light then shines beams to the tops of the nearest other towers across the world. Those then light beams to the towers nearest to them and so on until all the towers of the world are connected by beams of light. Then each tower releases a wave. Every creature on earth feels this wave as a subtle vibration that goes through their whole body. Even Commander Myada and every member of Rose squad feels it, but they can’t quite place how it happened or what it does. Most people just assume it is a simple shiver going down their back and think nothing else of it. But everyone keeps their eyes on the sky as they witness the beams of light cross their vision.

Melissa's sitting outside with a bottle of wine, and looks at her communicator. Lizette hadn't contacted her in hours, but someone performed the ritual, and one way or another, that was going to inspire a change.

"What the hell" she figured, as she opened the wine, and poured herself a glass.

This was where things were going to get interesting.
