Zack couldn't resist, his mind had merged with that of the little girl mind put within him. He wanted this now, he couldn't deny it. So he aligned her daddy's cock with her little pussy and started pushing it inside her. "Ohhhhh, yess daddy, I want this!" she cried out, however Mason stopped her. "I want you to call me Mason this first time, I want to make sure it's you that I'm fucking the brains out of dad." this excited Zack, he responded, "Of course Mason, whatever you say, your daddy will fuck you, just like the good little girl he is!". At this Zack plunged the cock into his pussy, he road it hard and fast, loving each second and each thrust. He noticed he was cumming, orgasaming nonstop, he then remembered the computer mentioning a "daddy-gasm" it stated that he and Mason would orgasm nonstop until a major building orgasm reached its peak, at which point they would have the most amazing of orgasms together. He couldn't wait. He moaned out his son's name over and over, "Mason......M....of fuck.....Mas.....ooooooh.....oh Mason......fuck me Mason! Fuck your daddy raw!!!!"
"Tell me who your daddy is dad!"
"You are Mason! You are my daddy!"
"Say it louder Zack!"
"YOU ARE DADDY!!!!!"
"Louder sweety!"
"YOU AAAAAAAAAARRRRRREEEE!!!!!!!!! FUCK ME DADDY!!!!!! FUCK YOUR LITTLE SLUTTY GIRL!!!!!!!!"
At that they both came, they saw stars as they both climaxed. The orgasms wracked their bodies for a whole hour, neither lucid enough to experience anything but the primal pleasure. Afterwards Mason's dick continued cumming inside his daughter's pussy for 30 minutes straight, during which time the two made out like a couple of horny hormonal teenagers, except it wasn't merely hormones, but love as well. Mason continued to call her Zack, as a sort of reminder of how he dominated her, how she was his prize. The familial love was still just as prevalent within Zack, but his mind told him he was the obedient one, the lover of Mason, her son turned daddy. She remembered he was her son but didn't care, if anything that just excited her more. The two would go on to fuck every day multiple times. Neither aged and eventually Zack had many children with her daddy. Her daddy would eventually turn each of them into obedient slutty little girls to have babies with. Zack didn't mind sharing, as long as daddy was happy, nothing else mattered.
After all, she loved her Daddy.
