Guy made his way out of the gym as inconspicuously as he could in his 300 pound body and ran to his car. He crammed himself into the compact and started his drive to Mr. Yuan's shop. He could hear his clothes tearing the entire time. "How big am I going to get?" He groaned. It got harder to turn the steering wheel as his pecs and biceps inflated.
40 minutes and 30 pounds later, he found himself at Mr. Yuans. People on the street watched the bulky young man pull himself from his tiny vehicle, his clothes shredding. He tried to keep his muscles from flexing, in an attempt to not burst from his clothing. It worked just long enough, as his swollen shoulders pulled open the fabric of his shirt when he entered the store, leaving him barechested in a pair of shrinking shorts.
"Mr. Yuan! Mr. Yuan! I need your help!" Guy walked about quickly, searching between the shelves for the little man as his shorts ripped open and fell apart. He groaned, knowing he was down to his underwear, but felt relieved that he wore a jockstrap today, so it wouldn't be ripping anytime soon. Once again, Guy heard a mandarin greeting coming from behind his wide back. Turning, he saw the little old man standing there.
"Why Guy! I hardly recognized you for a moment there. How does it feel to be big?" The little old man queried. The now 350 pound 21 year old tried to think of a proper response, but opted to ask a question instead.
"What's happening to me, Mr. Yuan? I'm getting so big, it's getting harder to move. None of my clothes fit me anymore!" Guy was starting to hyperventilate a bit. Mr. Yuan lit some inscence before answering and placed it on a shelf near them. The smell was kind of soothing...
"Calm down, Guy. The cream I gave you is indeed the cause of your new stature. Unfortunately, that's all I can tell you. You see, the cream has a unique property, very mystical. It gives the one who uses the cream the body they always wanted."
"Wh..what?" Guy stammered "I never wanted to be THIS big." He grasped his massive pecs with his hands. Mr. Yuan grinned again. "Maybe you didn't want to on a concious level, but in your subconcious you might want to be larger than you though you did. Don't worry, son, when you reach the size you want, you'll be very happy with it. Stay here until you stop swelling, and we'll get you some clothes to fit your new frame."
Guy looked down over his huge chest as he began closing in on 400 pounds. He didn't really have a choice at the moment... maybe he could find something to fix this in the shop as well...
"Allright, I'll stay." He said, peering in a mirror hanging from the back wall, watching his muscular body grow before his eyes.
