Andrew was still studying his new, muscular body in the mirror and trying to think of a store that sold clothes which could stretch. He had grown so much since he bought the ointment at that little store in Chinatown that he was sure nothing he already owned would still fit him, or if it did, then certainly not comfortably. He had just about decided to try and find something on the Internet when he got distracted by some kind of movement in the mirror.
He focused his attention on his reflection, and gasped when he saw what was happening. Whereas before his muscles had only grown after he had eaten or when he exerted himself, something seemed to have changed now, for they were growing right before his eyes, even as he just stood there.
For a while, he was too caught up and fascinated to do anything. All he could do was watch his already big pecs swell even larger, examine his slowly inflating biceps, and generally admire his thickening body. He was reminded of muscle morph videos that he had seen posted on Youtube, and which he had always thought kind of hot, but seeing it happen like this, and to himself... this was something else.
