She looked at him, smiling, as she gently leaned in, her massive tits resting on his lap as she looked into his eyes. She smiled and kissed him, his eyes widening as she did.
"Zoey! What the fuck! You didn't change anything yet! We're still Brother and Sister!"
"Hehe Yeah, I know. Think about it though. I can always change you into my boyfriend or my step brother after we have sex but right now, its...forbidden....its taboo... we're related...the idea of us...together is way way WAY hotter than I can imagine..."
She reached her hand into his pants, gently gripping his cock, rubbing it up and down, causing him to groan. His penis was harder than he ever thought possible.
"I'm forbidden fruit right now brother. Plunging your cock inside of me would be the ultimate taboo. Don't you want my tits when they are supposed to be off limits?"
His mind was going at a mile per second. His cock ached with these new thoughts she put in his head. The ultimate sex fantasy...his sister...and she wanted him, he leaned up and kissed her deeply.
"Oh god, I can't take it anymore, you promise you'll change me into your boyfriend or something after this? Please Zoey, promise me!"
She grinned
"Of course"
As the undressed, Zoey got up. Arthur looked concerned
"where are you going?"
"I just need to pee really fast"
She closed the door behind her and she pulled the dictaphone from between her massive tits. She smiled and brought the device to her lips and began to whisper into it, so Arthur didn't hear.
"Arthur won't be aware of these changes i'm about to make. Once Arthur cums inside me...he will change his mind. He will become obsessed with me as his sister and lover, wanting to do this as often as possible. He will want to remain my little brother. He won't mind me fucking other guys or women either. Our parents will never catch us in the act, something will always distract them at the last second, however Arthur will find it even hotter when we're almost caught. Arthur's cock is also big...big enough to fill me completely. He's too big for even the biggest condoms.. His balls are also huge and full of cum, able to cum multiple times. Also...my boobs are twice as big as they are now, but I still have no back issues and I can carry them around perfectly fine...and i'm still growing.
She was about to release the button when she thought of what if Arthur got her pregnant....oddly the idea of having her brother's child wasn't digusting her...but rather turning her on... but she remembered what happens to children of incest....she grinned
"Any child conceived from me and Arthur will be born without defects. Girls will inherit my boobs and boys will grow up endowed like Arthur. Only Arthur is able to get me pregnant as well.
She let go as the Dictaphone did its signature Spark and she moaned as her breasts, already beyond cup sizes, began to swell. She rubbed them madly as she grew...and grew...and grew! Memories flooded her head of having to buy her 1st bra at age 7... and outgrowing it by age 8....and so on. At age 12, entering a K cup, her mother asked her if she wanted a reduction or to stop her growth. She chose Neither. At Age 14 she stopped going to school and started being tutored due to her breasts being a vast distraction from everyone. When she was 18 she stopped wearing shirts around the house due to always outgrowing them and now at age 21, she had to go through doors 1 breast at a time to be able to get through them. She had fucked almost every boy in town except for Arthur, her one true target but that was soon to change...and forever as well.
