Timothy pulled out the experimental key he'd put in and smiled. "Let's see what these things will unlock," he thought to himself, picking up another key and inserting it in the lock. After a little experimentation, he found that it corresponded to the third gemstone. Satisfied, he pressed the button and turned the key. It clicked in the lock.
Slowly, he opened the lid and looked inside.
A sudden, unexpected flash of light seemed to erupt from under the lid and Timothy nearly dropped the chest in surprise! He blinked several times, stepping back. "Damn," he muttered, balancing the chest in one hand while rubbing his eyes with his other, "flash paper?" Spots swam before his eyes as he blinked rapidly to clear them.
Still, as he did so, he felt ... oddly. His pants seemed to have gotten a bit tightly bound around his groin and the uncomfortable sensation needed correcting rather quickly. Putting the chest down, Timothy pulled and tugged at his tight jeans.
It seemed to have little effect; in fact, the tightness only felt worse as he looked down to adjust himself further.
His hands froze and his eyes grew wide. Normally, were a stranger to see him, if it weren't for his Adam's apple and lack of breasts, he might be mistaken for a wiry woman. But now, before his eyes, his pants were sporting an enormous bulge between his legs!
He shook his head to clear the shock of the sight and stared again. The bulge was still growing! Another shock of tight, binding discomfort brought his attention back to the immediate problem. Desperately, he unbuttoned his pants and moved to unzip his fly. He didn't even need to try.
The pressure from inside, pushed the zipper down with a metallic sound, his briefs springing out with their huge load barely contained within. In fact, as he stared down at himself, he could see tears and long, slender rips appearing in the nylon of his underwear. It already looked like he had stuffed a banana and two tennis balls down his pants and it still was getting bigger!
