Arthur groaned as he tried to play his newest video game but he had the head of his sister in his lap, her mouth going to work on his throbbing erection. Over the last few days, Zoey has kept up her regimen of taking her birth control pills and has kept her growth going. She has grown well into the double digits size, now standing a massive 12 feet tall, almost twice as tall as your father and easily twice your height.
The Kinky games also continued, as the bigger she got, the more she wanted to try. Today she has tied a piece of string tight to the base of his cock, to prevent him from cumming, and is giving him one long constant blowjob, only allowing him to cum once he defeats a boss on the hardest difficulty with from a new game. She lick and slurps his cock, causing his legs to press inward, his legs pressing against the soft, malleable curves of her enormous breasts. She had recently graduated beyond Cup sizes, no bra maker could keep up with her growing demand. In order to provide herself with support, she has to use two sheets, wrapped around her enormous breasts, her neck, and back.
Arthur groans, he desperately want to cum but the string on his cock prevents him from doing so. He wants to reach down, but his sister keeps the base of his cock and the string, securely in her mouth. The force of her mouth is like sticking his dick into a vacuum cleaner but with much more pleasure and control. he dies once more to the near impossible boss, forced to start the fight over from the beginning.
Arthur and Zoey's parents have taken Zoey to every specialist they could to help control or even stop their 12 year old daughter from growing. However nothing they tried works and only seemed to fuel her growth. However to the doctors surprise the growth wasn't causing bone and muscle degradation, rather the opposite was true. The bigger she got, the more her body adapted to allow her to continue growing. Zoey seemed happy when she got that news. She loved being bigger than everyone, especially her boyfriend brother.
Arthur groans, as he nearly has the boss, when Zoey grins, and sends her enormous tongue across his sore and swollen sack, sending such intense pleasure he arches his back and loses the fight. He curses to himself and begins the fight anew.
During her time at the specialists, she was able to convince them to allow her to continue her birth control regimen. They studied the pills and found nothing out of the ordinary. She told her parents it was just to help regulate her period and that she wasn't having sex with someone they didn't know. Smiling at the fact she didn't technically lie, the doctors watched Zoey for a few days, growing bigger and bustier without them really realizing why. She however would sometimes grow bored in the hospital and convince a doctor or two to sneak her into a room without cameras.
Meanwhile, back in the present, Arthur finally beats the boss. Zoey smiles and gets up off his cock, grinning down at it. She then turns around and gently lowers her pussy down onto his throbbing erection. Groaning at his sister's soft, yet tight pussy gently lowering itself onto him, he looks forward at the mountain of an ass before him.
“...p...please Zoey....let me cum!”
She smiled, loving the feeling of being in control of the situation, she decided to tease him a bit more.
“let me consider it, my lil man”
She smiled and continued to recall her time at the hospital. She learned she loved being in control of her sexual escapades, but she always made her lovers do one thing. She lifted this young, handsome doctor to her face, snaking her tongue into his mouth as his hands rubbed and played with her massive bosom.
“mmmm....if you want me....you have to call me little sister....”
“oh god...yes....little sister...”
“Oh big brother! Take me now!”
She moaned as he trusted himself into her. She didnt care who was pounding her pussy, as she was thinking of Arthur, her real big brother the whole time. Yes this stud had a bigger cock, but it wasn't the cock she wanted. She was just using him to get off.
Back in the present, she finally reached down, and pulled off the string. Arthur groaned as he immediately began to cum. Filling his giantess sister with glob after glob of his built up semen.
She grinned, as he passed out against her soft, but enormous body. Kissing his lips as he slept.
“I missed you my brother....sorry I was gone for a whole week and grew so much without you....”
She then grabbed one of her pills, and popped it into her mouth, swallowing, feeling herself inch up a little more.
“But I plan to grow a lot more....just for you!”
