Ken was almost afraid to lift his bed sheets when he woke the next morning. He hadn't had any more serum, but the tent under the covers looked a lot bigger than 7 or 8 inches. He flipped back the covers and gasped.
His cock was over a foot long erect. It had slipped out of the fly of his boxers, and was hoveringly menacingly in front of his mouth as he sat up in bed. He licked his lips, as he thought for once he'd actually be able to give himself a blow job. Just the thought of it sent him over the edge, and his cock exploded covering his face and chest in loads of cum. Only as he climbed out of bed did he realize how heavy his balls were now. They looked like a couple of softballs jammed into his scrotum. He wiped the cum off guessing there had to be at least 6 ounces worth. Then he snapped some photos for the doctor. Maybe with the photos and measurements and crap, the guy would do something to stop Ken's abnormal growth.
Seven inches in one night? Would he be 21 inches long tomorrow? His cock had actually doubled in length and girth, would it be 28 inches the next day--and big as a baseball bat? He shivered, and headed to the showers. A cold shower might help.
Ken was miffed that he had to adjust the shower head downward, whenever he got it set to the height he wanted someone would move it. That's dorm life for you.
After his shower, Ken dutifully weighed himself. In spite of the growth, he'd actually lost weight. He now weighed 169 lbs. It wasn't until he pulled on his jeans that he realized he'd lost more than weight. His jeans were 3 inches longer than usual. Ken hurriedly marked the wall, and read his new height...it couldn't be. His cock and balls were growing, but the rest of him was shrinking.
He grabbed the phone and dialed the doctor's pager.
It took about 20 minutes, but the doctor called back.
"What grew another inch, Ken?" he asked testily.
"Try another 7 inches--my cock is 14 inches long, but that's not the worst of it, I'm 3 inches shorter!"
The doctor's voice perked up with excitement, "Conservation of mass of course. I bet you lost weight too."
"Yeah! Now what are you going to do about it?" Ken asked angrily.
"Part of the mass converting to energy to fuel the changes," he said in distracted way. He continued, "Ken, you get dressed, wear something loose and baggy and bring an overnight bag, and we'll see you at the lab first thing this morning."
