Curious as to how big he would get, Ken quickly too off his pants and underwear to see that his once 3 inch flacid penis was now well over 6 inches soft. More and more it grew, easily passing the 2 foot mark. It was then that Ken realized his problem, because he didn't care about the size of his penis it would continue to grow and grow increasingly. Scared of how big he would get, Ken tried to grab the notebook and turn to his page fast enough but his dick was already well over 4 feet soft now. Grabbing his pen, Ken saw that his penis section read.
Penis
Still growing into adult hood.
Erasing that mess, Ken wrote for it to stop growing. When he finally put the period at the end it was to late as his dick was well over six feet long soft. Not sure what to do now but unwilling to return his original change, Ken just sat where he was and waited for something to happen. It was in that moment that his sister Veronica walked in.
Veronica had changed to a drastic degree as her once normal looking breast had grown well in to H cup territory while she had shrunk down to 4'6" tall giving her a top heavy look. Seeing his sister the way she was now, Ken couldn't help but get a boner that reached well into the seven foot range. For some reason Veronica didn't seem to care though rather she seemed enticed instead by the sight of it before walking over and wrapping her massive jugs around the base of his two litter bottle wide dick. Unsure with how to respond, Ken simply let it happen.
As his body continued to fill with lust from his sister's short boob job Ken noticed a burning sensation all over his body before muscles started to appear from the new testosterone in his body. Pound after pound appeared until Ken looked like a professional body builder. Next, Jen's bones started to crack as the forcefully elongated until he was as tall as his dick and making the uncaring Veronica reach the very base of his dick due to his new height. Finally was his balls as they started to fill up with cum for his new rod. The balls grew and grew to match his size before stopping at the size of large beach balls that sagged from Jen's scrotum like a pendulum.
Finally, after all the changes, Ken could feel his lust reaching critical before it finally opened the newly made floodgates as gallon after gallon of cum left his crotch and coated Veronica though she didn't care.
After 20 minutes of orgasming, Ken could see his entire room and sister was covered in white before it was all sucked away. Looking closer, Ken saw automatic vacuums attached to his walls sucking in the white goop. Somewhat satisfied, Ken looked through his notebook for anymore fun changes he could commit while Veronica was now under his desk servicing him with her entire body and using her own weight to keep it down.
