"Finally, your dick grew."

"Hannah? Since when are you there?" Emma asked, trying to hide her dick, even though it was too late for that.

"From the start. I realized you were acting weird before and I just pretended I left, waited a minute and sneaked in without you noticing." Hannah said

"I do not believe, you have seen all the shameful act that I have done now. Please, you can't tell any of this to our parents." Emma said

"Calm down Emma, ​​you needn't be ashamed. Mom and I were already thinking that your dick would never grow since it was taking too long." Hannah said

"What did you mean by that? Did you and Mom already know that this was going to happen to me?" Emma asked

"We believed so. My dick grew when I was 16, but with you at 19 we were already losing hope." Hannah said

Emma, ​​on hearing this, advanced against Hannah and, grabbing her arms, asked "Did I hear what you said right now? Do you have a dick too?"

"Yes, I have. Mom also has one. This is a genetic factor in our family that causes most women to grow a dick." Hannah said

With that response, Emma finally realized that she had never seen her mother naked, and that Hannah had started to refuse to be naked around her at age 16, a fact she believed was because of the adolescence that made her want more privacy.

"Hannah, I'm still having a little trouble believing. If what you say is true, then you have to show me your dick right now." Emma said

"No problem" Hannah said, so she removed her skirt and panties. She was enjoying her sister's attention, so much that her dick got hard.

Emma can hardly believe it. According to her estimates, her cock was 5 inches long, but Hannah's cock was at least twice the size, and to top it off, she also had balls.

"No way. How can it be so big? And you have balls too, does that mean you no longer have your vagina?" Emma asked, getting more and more curious about it.

""It really is big, but yours will probably be as big as mine when it finishes growing, if it is the same it was with me it will take a week for your dick and your balls to finish developing. And for the other question, it is obvious that we kept our vaginas. I said it’s hereditary, and you know that our father is 100% male. If the vagina were lost, we would never have been born." Hannah said
