"I will become one with you. I'm sorry, but indirectly you ended up being cursed too, and there's nothing I can do to help you. The curse is too strong for the effect to be avoided and I wanted to let you know beforehand so you don't get caught off guard." your girlfriend said
"But how could she curse me if I wasn't present at the scene?" you asked
"She didn't specifically target the curse, she said the curse would make me physically inseparable from the person I most trust who is not part of my family. It turns out that this person is you." your girlfriend said
"And when will that happen?" you asked
"According to her, a few minutes after we met in person, if I avoided you for too long I would come to you sleepwalking. Judging by this it should be happening any time now." your girlfriend said
The wait was only a few seconds, after which your girlfriend static in a rigid and upright position, then she began to float while a strong light was emitted from her eyes and mouth. You grabbed her legs and tried to pull her back to the ground, but she was still in the air and you couldn't move her. Then it was as if gravity had been turned off in the room, not only you but everything in the room began to float freely in the air, just like that before your girlfriend emitted an intense flash that completely obscured your vision.
Lost in the glare you felt that you were suddenly naked, and then something else was happening to you that you couldn't see. With the curse being real, you knew you were fusing with your girlfriend, and you imagined that would be the result.
Faster than it started, it ended. The flash disappeared and everything floating fell to the ground, including you, who fell sitting on the ground. Immediately you decided to check the final result and looked at your body, which was now exactly your girlfriend's body with a single difference, a dick that you recognized as yours, only a few inches larger, which was found between your legs.
Even though your bodies merged, you didn't feel any difference in your mind, so you looked around and found, attached to the left of your head, a second head with the same appearance that you knew from your girlfriend was looking directly at you.
"You look good like that Jack (you)." your girlfriend said
"What do you mean by that?" you asked with your voice, which now was exactly like your girlfriend's
"It will be easier if you see it yourself." your girlfriend said and you got up. Taking the opportunity to learn to control the body you shared now, discovering that both could control you had control on the right side and she on the left side, but if you allowed it, you could let the other move your side, thus controlling the whole body.
Allowing her to control everything, your girlfriend took you to her wardrobe, where she opened the door and you stood in front of a full-length mirror that was inside. In the reflection what you saw was a reflection of your girlfriend practically unaltered, except for now having a dick and two heads between her shoulders, the head on the right being yours. Yourr head had changed and now both your face and hairstyle were an exact copy of your girlfriend's.
"It doesn't look bad at all, it could be worse. And is this what it feels like to have a dick?" your girlfriend said and your dick got hard.
"You don't seem the least bit surprised by this." you said
"It's probably because I was already resigned to the curse and had an idea of more or less what the end result would be due to the explanation the witch gave me. She had told me that if the person I merged with was a male, it was almost certain that both of our genitals would be retained. My vagina also still exists, see." your girlfriend said and slipped her hand behind your balls, where it circled her fingers around the edges of an entrance you had never felt before, which you recognized as her pussy "The only thing that surprised me a little was that we now have two heads. Now I understand what the witch meant by even becoming one we wouldn't lose our individuality."
