you begin to understand...

A long time ago there existed a powerful entity. their power were vast and their knowledge advanced. A fearful ancient civilization devised a plan to seal the cosmic god, separating their powers into parts, trapping it in objects. These objects would remain inert unless they all came together, and even then it would take three humans to unlock the seal.

For centuries different humans tried to free the entity, mostly for selfish reasons, but all failed. Sometimes only a human would try. Sometimes those who tried did not have all the objects. Even when all the requirements were met, nothing happened.

The truth was that the seal had hidden requirements. The three humans had to fulfill certain special characteristics, characteristics that humanity would never fulfill, or so the ancients thought.

The three humans had to share a bond as sacred as it was corrupt. They too must have shared a betrayal. Only the first human needed to be a complete female. The second human was to be a female trapped in a male body. The last human was to be mentally gender neutral, but physically male. The three of them must be willing to come together in unimaginable ways.

Zoe was born Zac. Having hormonated her body during puberty, she was mostly female, even though her genitals were male and, despite female hormones, fully functional. She met you and Mandy during her teenage years, when her dad fell in love with your mom. you were her biggest support during her transition, and even though you should have grown up like siblings, Zoe and you secretly loved each other.

Mandy was your girlfriend. Once the best of friends, adolescence blossomed that friendship into love. When Zoe, Zac back then, came into your life, Mandy was immediately attracted to him, even if she hid it well. When Zac revealed himself as Zoe, Mandy began to be jealous of her. Not only did she feel the attraction to Zoe increase instead of decrease, something that wasn't supposed to happen since Mandy was heterosexual, but she watched as Zoe and you grew closer and closer. Finally Mandy decided one day to seduce Zoe, telling herself that she just wanted to understand why you loved her so much. Zoe didn't resist, justifying herself with the idea that she would show her brother the kind of person his girlfriend was and then Mandy would be out of their lives forever...

It didn't work, of course. Not only was the adventure too exciting for them, but eventually their feelings for each other deepened. It all blew up when you caught them together, but by then they had a plan.

You were a very insecure boy. you never really felt like a man, but you just thought it was insecurity or something. After all, you weren't like your sister Zoe, you didn't feel like a girl either. You always felt guilty about falling in love with Zoe, especially with Mandy already in your heart and with Zoe being your stepsister, but that taboo made you even more excited. You dreamed many times of Zoe and Mandy together, but even then that didn't prepare you for the rush of emotions you felt when you caught them together. Love. Betrayal. Jealousy. Lust. Desire. Pain. Most of all, you felt deeply inadequate and humiliated...

When you put on the costume, you inadvertently ticked all the boxes. You were a non-binary person, even though you didn't know it. You were born a man. You had a girlfriend who felt like a female. And you both shared a stormy relationship with your own stepsister, a transgender girl who had taken hormones during puberty even though she hadn't eliminated her male genitalia, functional despite the hormones. Neither Zoe nor Mandy knew, of course. All they knew was that the strange set had attracted them when they saw it, and they had thought of you. They decided to give it to you as an apology, hoping to catch you wearing it. Not with humiliating intentions but naughty. To some extent, it was good that they were unaware of your insecurities and your true feelings regarding your gender, because they would never have dared to even have an affair. Not if it meant hurting you so much...

When the three of you merged and your body finished reorganizing, your girls were finally able to access your true desires and feelings. The pain you could sense from them realizing the true extent of their betrayal tore through you like a red-hot, spiked, acid-coated iron. Feeling your pain made it even worse for them. In the midst of emotional chaos you managed to make yourself heard. A small thought. a faint whisper. just a spark of feeling.

"I still love you… Both of you. Please, I need you…"

The burning love and twisted desire that filled you then, were overwhelming. How could a love so pure be so entwined with a desire so perverse? You didn't know it, but you understood it. Because that was how you felt about them. And now they both knew it, since they could read you and feel you as much as you could feel them. And it felt so overwhelming, yet so perfect.

You took shape quickly, leading the process but being guided by the two girls. You were the master of this union, so their powers belonged to you even if they wanted to oppose you, which they certainly weren't. The feeling of love and desire that both of them sent you through the bond, caused by they being **** to helplessly obey you, even if they really wanted it and therefore they were not truly being ****, clearly told you their opinion on the matter.

"Fuck! Oh god! It feels so good!"

Neither of you had the ability or mental clarity to think much beyond the overwhelming pleasure or burning love you could feel coming from the other two. You almost didn't want to part. But despite everything, you still wanted to share this as separate entities, so you sped up the process of forming your new body as much as you could...
