But first...

Chris soon found himself lying on his back with his beloved sister straddling his hips. She had positioned herself so that his cock was between her buttocks, gently moving her hips to give him an ass job.

"Fuck lil sis. You feel so good!"

Lily didn't reply, her mouth being too busy kissing Ai to be able to. Ai herself swung a leg over Chris's head to sit on his face, her soggy hairless pussy in need of a good eating.

"That's right, master! Just like that! Oh Lils, he eats me just as well as you do, baby! It must be something genetic..."

The three of them continued like that for a while, Chris happily devouring Ai's pussy while receiving an ass job from his sis, the two girls kissing and fondling each other's breasts in the meantime. They eventually moved on, Lily getting into a reverse cowgirl position but with her cock in front of Chris's. Ai managed to sit on top of them, taking Chris's cock in her ass and Lily's in her pussy. Then she turned around and switched the hole she was taking each of the two cocks with. She repeated this several times very slowly, all three enjoying the moment. Chris had sat down to pet both girls, kissing them from time to time as well.

"Ai, I want you to ride me, with our abilities it won't be difficult."

"Wait, but how is Chris going to fuck you then?"

"Like I said, I'll use my abilities. Besides, you'll need to use yours, I want you to be in reverse cowgirl so you two can look at each other. I…I want to be your little toy this time, if that's okay?"

"Whatever you want, sis. We'll do what you want, for a while at least. I'd like you to ride me too."

"Do you want my tight little ass, or do you prefer my wet pussy, little brother? Both will accept you. Remember that I I'm still your genie, you can ask me for any sexual desire you want too. Do you want a tight and wet ass capable of milking you? Or maybe you want a full vibrating pussy of little bumps? Wish what you want, my love. I'm yours to use."

Chris reached over to hug his sister and entangle his body with hers. Their mouths intertwined in a passionate and loving kiss, tears of emotion rolling down their cheeks. A gasp and a pair of arms wrapping around them let them know Ai was there, tears rolling down her cheeks as well. The excitement and passion they shared was overwhelming all three of them.

"I want our bond to allow us to share emotions and sensations, as well as thoughts at will..."

Lily shuddered slightly, a mini-orgasm coursing through her as her genie powers kicked in to fulfill her brother's wish. Soon the three of them felt the echo of each other's bodies. The arousal, Chris and Lily's shared boners, Ai's wet pussy… All of that was outweighed by emotions, however. They could feel the genuine love they had for each other, the kiss between the two siblings slowing and deepening, the two immersing for a moment in their shared love as they felt Ai's love both for them individually and for the situation they were experiencing at the moment. She loved them, and she loved their shared love.

"I love you both so much!" The three of them threw this thought towards the others.

Lily and Chris began to move their hips gently, rubbing their cocks together. To everyone's surprise, the demonic organ seemed to painlessly open up and envelop Chris's cock, both siblings moaning together.

"Fuck, little brother! You're literally inside of me! God! This is…Fuck I love you Chris! Your sister loves you so much, baby..."

"Damn, sis. I'm fucking your dick, baby. Shit, I'm about to cum, honey. I can't take it anymore, it's too much. I love you. Oh god, I love you, Lily. I'm going to fill you up, my love. The cum from your little brother's balls is going to fill your own balls soon, babe. They are going to mix. You want it, don't you? You want to ejaculate our mixed cum in our girl's ass, right? I know you want it, my beloved horny little sister. She wants it too. Look at her, Lily. Can you feel her desire for us, my love? Do you feel how much she loves us? She loves to see us like this too. As much as we love seeing her with each other. Here it comes, sister! Take it all! Fill your horny balls with your incestuous brother's cum! Your balls belong to me now, little slut! Say it! Who do you belong to, bitch? Say it!"

"You! Fuck, I'm yours! Your slut sister belongs to you! Her dick is yours! Her balls are yours! Her body is yours! God, even her heart is yours... *sob* I love you, Chris. Oh baby, I love you so much! Fill me, fill me, fill me! Fill my balls with your cum! Claim me, baby! Make me your slut, your own personal stud! Make my cum your cum! Oh god, yeah! Yeah, yeah, yeah , yeah! Fuuuuuuuuuuck! Oh babe! Yours, I'm yours! Yours, yours, yours! Shiiiiit! Holy fuck, Chris! Your sister belongs to you now, my love! Forever! Kiss me, Chris. Please baby, oh god, I need ...Oh honey, I need you!"

Chris devoured his sister's mouth without hesitation, growling domineering as she moaned submissively. None of them could help it, even if they wanted to. Still, he submitted afterwards. He moaned submissively in his sister's mouth as she purred and thrust her hips against his, sucking even more of his cock inside her. Her eyes met, equal parts dominance and submission in their shared gaze. Two simple words in a mutual mental loop. "mine. Yours."
