A non-binary body at last.

The blend of powerful magic and advanced science from your two mates achieves the impossible. Your body transcends human biology even though it remains mostly human. Your genetics, your brain and all your organs have been optimized for perfect metabolism and health. Even then, you possess external chameleon abilities and a minor shapeshifting ability.

You have functional ovotesticles. each month you will go through a heat cycle, timed perfectly with that of your queen, Mandy. You will want to mate with both of your partners. After all, the special semen of your magical familiar, Zoe, will nourish your eggs and your own semen. You will be injecting Mandy with such a cocktail very often, and you will wish Zoe would do the same. Luckily, Mandy has a second vagina due to the partial hybrid transformation, and Zoe is now a full futa, so you'll be able to keep fucking them even while they're fucking each other.

As a consequence of your entire transformation process, Zoe is sterile. She doesn't care because she already was. Female hormones and male genitalia don't get along particularly well, it seems.

"That doesn't matter, love." A firm pair of arms wrap around your small frame, and you turn to meet your sister's face. You have to look up slightly, but it was always like that. Despite your androgynous features, you are not too small. She's just a bit taller and more athletic than you, but not by much. Besides, you don't mind too much having to look up if that deep kiss is what you're rewarded with. No, you're certainly not complaining. Your cat tail is raised in happiness as you purr. You are a catfolk now.

"I never..." The new soft, small, sad voice, accompanied by a sob, makes you stiff. You and Zoe react at the same time, turning to take Mandy into your arms and pull her lovingly towards you.

"It's okay baby. SSh, it is, I promise. I know you can feel it too. You know I'm not lying to you. *Sigh* I love you baby. I never stopped. We love her too. We all three understand each other now. We'll get through this. The three of us together..."

You are interrupted by Mandy, who rushes towards you in desperation, trapping your mouth in a needy kiss, as full of desire as it is of love. She presses her body against yours, both of you sighing and moaning softly as you deepen the kiss, Zoe caressing your necks and backs lovingly.

"Fuck, I want you," you moan. "Both of you!"

You barely have time to put up a protective barrier around yourselves to prevent your mating from damaging the house before your two girls pounce on you. Claws and mouths are everywhere as your clothing is torn, the remains simply disappearing as the fabric is a mix of magic and solid hologram. You moan and growl, submissive and defiant at the same time. You will surrender to them, but you will never submit. Part of you is still an alpha and that will never change.

Mandy is freaking out. On the one hand, her new queenly instincts tell her that you must serve her, but her own human mind loves your fight, and all of her cybernetic systems are programmed to obey you. These contradictions, instead of paralyzing her or creating problems, intertwine seamlessly so that your queen knows her place. She belongs to you as much as you belong to her, and every mating will be a struggle. You're not challenging her, you know your place too, but you both love this.

"Fuck yeah!" Both you and Mandy grunt in unison as she impales herself on your stiff member, the little spines that cover it scratching Mandy's pussy and setting her nerves with pleasure red hot. Her jaws, partly insectoid now, catch your neck and bite, injecting an aphrodisiac cocktail into your blood. Although it is not necessary, your queen keeps her jaws locked on your neck for a little longer than necessary, simply because she knows that you love it somehow thath she can feels through your shared bond. You return her favor by sinking your own fangs into her clavicle, a point of pleasure in her new physiology.

Suddenly, Zoe's body slams into your back, her hard cock between your buttocks as she humps against you, breathing into your ear. "I want you so much, brother..."
