When did you become a futa?

With the change, theres a faint memory coming into your mind that sometimes around 18 to 21, a man or woman, under the right cercumstances, can turn into a futa. First learning of it you didn't really think much of it as most kids do, but as you began to mature and started getting hard and jacking off to Mommy K, you sometimes rubbed under your balls, as it tingled oddly. One day, you came to Mommy K, recalling change possiblility and your heart fluttered.

"Mom," you say with a nervous gulp, pressing a hand to your chest. "When did you become a... a futa?"

Mommy K frowned. "Well, I was born a futa, but sister was born a boy that changed whe stime time before she was nineteen. Same with your cousins Alia and Eva, they were born boys then became futa at the same time," she then rubbed her chin. "Personally, I'm not entirely sure what the factor is. But why do you ask?"

You gulp and your eyes focus on the table. "I... want to be one too... I've graduated highschool, yet nothing has started... will I ever become one?"

"Do you have a boy or futa you like?" Mommy K gives a wolfish grin, proud that her son might fancy someone.

"Yeah, I do," you nod, staring at the pink, perfect lips of your futa mother. "I just want to be like her before I confess my feelings..."

"Well then, do you want to see your aunt and cousins then?" Mommy K smiles, pulling out her phone.

"Yeah, I'd like that a lot, mom."

After a few seconds of waiting, Mommy K smiled. "Hey, sis, how are you doing?"

For a time, you just stand and listen to Mommy K catching up with her sister, talking about recent events and what their children were up to, which then lead to you. "Oh, would you like John for the weekend, I think he might want to talk to you and his cousins about something."

You are quiet as you hear the faint murmur over the phone, Mommy K nodding and smiling, offering the phone to you. "Here, your aunt wants to talk."

Taking the phone and putting it to your ear, you breathe easily. "Uh, hello?"

"Hello, Johnny!" A bubbly voice greeted. "I can't believe you want to visit us, we'll have so much fun!"

"Yeah, I guess so."

"The flight over won't take too long, but it'll still be tiring."

"Okay, I'll see you soon."

Hanging up the phone, you hand it back to Mommy K.

"Well, on Friday, I will drive you to the airport as soon as you get home, okay?" Mommy K grinned and flicked her cigarette to the ground.

"I can't wait, mom," you say as you return to your bedroom, on your bed you start huffing jerking off and rubbing under your balls as it ached needy. You pant as sleep takes you.
