-three days after Trannia's birth-
**Mary's POV**
Today is Sunday and we are in the cabin that was rented to celebrate my birthday. We have a place to get out of this because she was on budget and had a small pool in her, and with the heat, we wanted a pool party.
I was so jealous because I was the only one of the four who didn't have a dick yet. Sometimes I would stare at the bulge in their bikini. But I don't know what got into me is so jealous that I freaked out when I caught Cristine and Samantha hugging and kissing as they rubbed their dicks together.
"ARE YOU GUYS DOING THIS TO MAKE FUN OF ME? YOU KNOW HOW MUCH I WANT A DICK, AND ARE SHOWING ON MY FRONT." I ended up screaming at them and sat in a nearby chair. They stopped doing what they were doing and looked at me in fright.
"We are not trying to mock you." Samanta said
"Yeah, we just didn't realize that you were feeling so bothered by it." Cristine said
Betty, who was in the bathroom, ran after hearing me screaming, and she had her cock hard and exposed, making it clear she was masturbating. "What's the problem? What happened here?"
"Looks like Mary is bothered because her dick hasn't grown yet." Cristine said
"But the problems easy to solve. I didn't say you grow faster with more sexual acts. We can help her here and right now with this. If the three of us fuck her at the same time." Betty said
"All three at once? Can it work?" I asked
"According to Herma this can help a lot." Cristine said
So I know the whole bikini, getting naked and said "So come and cum as much as you can in me."
Then the three of them got naked and Samanta lay down on a pool lounger, telling me to sit on her. When I went to sit on her lap, Samanta positioned me so that her cock came into my anus. She pulled me practically lying on top of her, Before I could complain, Cristina was in front of me, practically lying on me and fucking my pussy. With both of them fucking me, Betty approached me, offering her dick for me to do a blowjob, which I did. We kept going like this until the three of them came inside me.
And it seems that this worked, because as soon as our organism was over, my cock started to grow. And as you grew up, my dick got huge, reaching impressive 16 inches long. And my balls are not left behind, since I ended up with orange-sized testicles.
I was so echoed by the situation that I immediately jerked off. My dick was so big that I had to use both hands.
"I can't see that you're enjoying this mom." I heard the voice speaking in my head.
"You must be my spirit daughter. Giant gift course you gave me, I'll call you Gigantia." I said and quickly I came. I was also impressed also with the amount of fucking I produced, Rivalring how much my three friends produced together.
After my orgasm, I examined my body closely, seeing how it went, and realized that my vagina was still there. All I could say is that this was the best birthday I've ever had in my life.
Next?
