**Betty's POV**
It's been 3 weeks since Cristine said I would have to wait until I grow up, and the more sexual acts I do, the faster it will be. Since then I've been having sex with Cristine and Samanta as much as I can if ekas aren't around I masturbate.
In the meantime, my brother, David, moved to city and came to live with me so we could share the rent.
We were alone at home with nothing to do, so I suggest we play some video games (I know it may not sound like it, but I'm kind of a fan of first person shooter games.) As we had fun, I didn't realize what was happening to me, in fact, David noticed before me.
He dropped the controller and said "Betty, look between your legs."
Just when I looked I realized that my cock had already grown. I was wearing short shorts because it was a hot day, and my dick was sticking out from under the shorts, right next to my right leg.
"At last my cock grew, I was tired of waiting." I said
"Tired of waiting? So this is real and did you already know it would happen?" David said
"A few days ago I participated in a ritual promised to bring a spirit to me that would grow this cock in me." I said
"Spirit? Don't tell me you were possessed by a ghost or demon." David said
"It's nothing like that, it's just a spirit of sex." I said
"Spirit of sex? Never heard of such a thing." David said
"I had also never heard until my friend Samanta appeared possessed by one. I don't know if everyone is like this, but at least spirit was possessiing her, possess women only, and it ends up making a dick grow in every woman she possess." I said, and then I took off my shorts.
"Hey Betty, why are you taking your clothes in front of me?" David asked
"I just want you to look at me behind my balls to see if my vagina is still there. Even growing a dick was no guarantee that I was going to lose my vagina so I want to know if I still have mine or not." I said
David looked behind me, just under my butt, in the space behind my balls and said "There is nothing here, your vagina is gone."
"It's because I'm here Mom, it's just a sign of my birth." a voice in Betty's mind said
"Who's there?" I asked, It was then that I remembered that a spirit would be born within me, and, by the way it was done, I thought it was normal to be called Mom. "You must be my daughter with Herma. Am I right?" I said, calling her daughter because the voice was feminine.
"Betty, who are you talking to?" David asked as he saw me talking to myself.
"With the spirit of the sex just born in me. My new cock proves it. And thinking better, if this spirit is my daughter, then she is your niece David." I said
"Niece? I wonder what our mother would say if she knew she became the grandmother of a spirit." David said. They both laughed.
"So come on, greet your uncle ....." just then I remembered she had no name yet.
"Unlike my father Herma, I can own both men and women, and those owned by me become shemales, also known as tranny. Call me Trannia" my daughter said when she noticed my doubt
"All well. So greet your uncle Trannia." I said. Unable to talk to David, Trannia gave me my first erection, so that my hard cock would ended pointing at him. My cock was 8 inches long when erect.
Another thing that happened was that I found out that I have an exhibitionist side, because the mere fact of having my brother seeing me with my hard cock, I got more excited, took off my shirt and started jacking off right there. But with my lack of experience with a cock, and the new sensations I was feeling, I came very fast. David jumped to the side so he wouldn't get hit by my cum.
