A test to change yourself, and it works.

Jake, having an idea of ​​what he wanted to do, called Kelly.

"Do you need me for something darling?" his cockmother said as she reached him, near the back door outside the house.

"Yes, I need you to get hard for me mom." Jake said

"The naughty guy is excited for mom, right? You could have called me in the sex room then." Kelly said

"No, I want to try something and it will be better if we do it here." Jake said and took his clothes off, then looked at his mother, who was already stiff, and asked her to lie flat on the floor.

Kelly did as her son asked and he bent down in front of her tip, stroking it a little before placing both hands on her urethra and stretching.

"I think I can get in." Jake said

The cockwoman was startled to hear this and started to try to say something, but with her son holding her "mouth" wide open, nothing came out intelligible.

Jake wished he could get in all the way to his mother's balls and he shoved his head into her urethra, then his shoulders and arms, then dragged himself deeper into her until he felt his feet go in too. It was pitch black in there and he couldn't see anything, so he wished the inside of Kelly was light enough for him to see. When he did that, as if by magic, he could see the path and the red walls inside her shaft. He then continued to crawl deeper, eventually finding a fork where he chose to go right, and in doing so he fell into a more spacious compartment filled halfway with the white, pasty liquid. So Jake was sure he was inside his mother's left testicle, where he already had more than half of his body covered in fresh cum.

"Jake, get out of there. I didn't know it was possible for you to get inside me, but I want you to get off my balls immediately. It can't be safe to be inside me." Kelly said

"I only leave here if I leave with your cum when you come." Jake said

"No, get out of there. I'm scared of what might happen to you." Kelly said

"Trust me mom, you'll like this and if everything works out it'll be better for both of us." Jake said and started stroking the inner walls of her mother's balls

"Okay, but if you see that it's not working out like you hope I want you to get out of there immediately." Kelly said and started moaning with the stimulation, Jake getting more and more covered as the level of the cum started to rise.

When the place was almost full and running out of room for Jake to breathe, the whole cum in the place started to get sucked into the hole he walked in, that meant Kelly was coming. He held himself in such a way as not to be sucked out and not to block the white liquid's exit.

"That was good but, are you still in there Jake? I don't see you out here." Kelly said

"I'm fine mom, let's go one more time and next time I swear I'll get out of here." Jake said

"Okay, but just one more time." Kelly said

Jake instead of stroking the walls of his mother's ball again, mentally wished "I want my body to become cum and mix with my mom's cum, but that won't be fatal. I will continue to live as a slime type of person, but with my body made entirely of my mother's cum. My humanoid form will be what she would most like to see in me." He then looked at himself, just a few seconds passed and his body started to melt and turn all white, mixing with the cum produced by Kelly and accumulating in her balls. Feeling himself mix with his mother's cum, the liquid becoming a part of him and him gaining control over it. Then Jake began moving its contents around, rummaging around inside and refusing to come out until he felt he had filled the place to the brim.

Kelly came once more, her cum spurted copiously leaving the lawn fuller of white in her second consecutive orgasm. She felt in paradise after such an orgasm, but she was scared when she realized that she no longer felt Jake inside her testicle. Not seeing him out of her she despaired.

"This cannot have happened. Jake, dear Jake, please answer me, tell me you're okay." Kelly said ****

"I'm here, everywhere." Jake said

"Everywhere?" Kelly asked

"Exactly, everywhere. I just gave you payback for making me worry when you became your dick, now I'm the one who became your cum." Jake said and Kelly was surprised to see the cum she had just ejaculated gathering in one place and rising up in a humanoid form.

When Jake finished taking human form, he noticed that he was much taller than before, but he knew that was because the amount of cum that made up his body now had a lot of mass. "So what do you think? Do you like my appearance?"

"I can't believe it, you look exactly like me when I was your age, only with one extra thing." Kelly said

Jake glanced down and saw that the humanoid body was that of a woman, but with a dick as big as the one his mother had when hers first grew, at least proportionally to her normal size, but judging that the amount of cum that filled his body made him three times taller and everything was proportionately bigger.

"How did this happen to you?" Kelly asked Jake

"Just like everything that happened to you until you became the dick you are now. I finally understood what happened and confirmed my theory. It seems that I have some kind of power that is making whatever I wish come true, but since I only made wishes related to you, and only now directly related to me, it's just the two of us that are so different. That's probably why no one made a fuss about or badmouthed you for what happened to you, because I deep down wished they didn't." Jake said

"Did you do it all? Incredible." Kelly said

"Now that we know that, if you want I can turn you back to normal." Jake said

"Personally speaking, I don't want to go back to normal. I'm enjoying being a disembodied dick and feel like I've never been happier as a human, but if you don't like seeing me like this and you want me to go back to normal then so be it." Kelly said

"I don't bother with that. I didn't say that you became what you are because I wished even if unconsciously. It means that you are now exactly what I want, and now I have my body completely made of your cum and I depend on it for sustenance." Jake said

"But what a lovely son, or should I call you my daughter?" Kelly said

"And to make up for everything I changed you without asking, tell me one thing you want and I'll grant your wish." Jake said
