Adjustments and Sister Sucking

While overall satisfied John felt he could go a bit bigger, another snap and flash of light. When it cleared he nodded with approval, his dick was now 30 inches long and 3 inches thick. His balls were a sizable 16 inches in diameter, bloated with sperm stretching his nutsac tight. His body bore toned muscle structures and he couldn't help but flex a bit. Luckily this new body had muscle control and he bounced his pectorals alluringly. But that was when the door opened, “Hey John I-” he turned to see his younger sister, Monica standing there looking his nude form, “I’ll just uh-” she said but John reacted he ran up grabbed her pulled her inside and then closed the door and locked it.

She staggered as she turned to face her brother, “John what’re you-” she began thens he saw his cock and her words faded into a weak mumble, “Hollllyyyy shit! You’re… huge! Is that what you’re always hiding under those baggy clothes.” John thought.

It was true he typically wore baggy clothes but more because before what just happened he wasn’t proud of his body. “More or less,” he then had an idea, he snapped his fingers, and watched as his sisters body changed before the snap she had a decent B-cup bust, and a 20 inch booty, stood around 5’2’’ and had blonde hair that was in a bob. After the snap her bust shot up to I-cup sizes huge perky breasts that defied gravity, her butt swelled up becoming a big bubble butt that was 40 inches across, she got a bit taller now standing around 5’6’’ a few inches shorter than you with your current body, and her hair lengthened till it reached the middle of her back. But that wasn’t all John did, her lips plumped up becoming great big dick sucking lips, and of course her body was changed, she could take him in his current size and after he came inside of her no matter how big your dick got or how much you shot she’d just stretch like rubber. But he made yet another change to her mind… and the best part? She wasn’t aware of it at all, at least John hoped she was. A test, "Hey sis your boobs look bigger you do something?" She smiled.

She gave a slutty giggle "No silly my boobs always been like this." He gave himself a mental thumbs up. Her eyes went back to his crotch "Hey bro can I, like, suck you off your dick is sooooooo huge!" She said.

John was a virgin and not one to pass up an opportunity for sex got onto his bed, "Hell yeah!" He said. She was on him in a second, she walked up to John and then grabbed his dick firmly, she brushed her hair out of her face and lowered her head those big, fat lips pursed and then they touched his dick head. He felt the pressure from the enlarged lips and the heat from her mouth, he couldn’t help it being a virgin he grunted as his dick bulged and his balls expanded a few inches and he began to orgasm into her mouth. Her eyes widened and she gulped it down hungrily every massive blast made her cheeks bulge only for it to shrink as she swallowed it. Every gulping mouthful bulging against her neck as it went down, John shot a total of 15 times for a time frame of a minute. When he finished he sighed with relief, but his dick was still hard, she pulled her head off and staggered back. He saw her belly bulging tremendously looking like she was 6 months pregnant. “Holy fuck bro, you cum, like, a lot!” she said, she then reached a hand for her pussy, “I’m soooooo fucking wet! I gotta have that in me!” She purred...
