Arriving at home after his expedition, Dean pulls out the belt to examine it closely. The belt was of very flashy design, with a simple pressure buckle to hold it. It was a very long belt; indeed, it was better suited to a giant than a human! Dean continued to mull over the old man's words. Somehow, they seemed suspicious, informative...
Dean decided to try out the belt for himself to see how it fits. He weaves it through his pants deftly, wrapping it around himself multiple times to conceal its length. He takes himself to a mirror to view his appearance.
"I see," Dean mutters to himself. "The design of the belt was probably to conceal the buckle. It just happens to assist in holding firm as well. That's what the old man meant." He adjusted the belt outward a bit to release pressure on his waist, until it felt snug.
Something seemed bizzare, however, in that action. Looking in the mirror again, it seems something was misplaced about him. The belt's end made its end noticeably lesser around the waist than when Dean put on the belt originally, yet Dean found no slack for the belt to be pulled tighter. He shrugged it off and bent over to fix his pant cuff. He made a slight grunt as he pulled himself back up, and took another check in the mirror.
What he saw afterwards brought the shock of revelation into him. The end, which made its way to his side before, now aligned itself with the first loop of his pants, and yet again there was no free tension to pull it back! Dean was dumbfounded. Exactly what kind of belt was this? Was it shrinking? Or...
Then it fully hit him. The man's words to shirk disbelief. This belt was no ordinary belt. Dean quickly removed the belt and eyed it closely. It still looked as long as before, which meant one thing.
Dean moved to the bathroom in haste. There he stripped and took notice of himself in the mirror. Something was out of place, and without the belt to distract him, he believed he knew what it was. He stepped on the scales and read off his weight. It seemed normal, yet something in the back of his mind was nagging at him, as if to say that it was wrong, and again the words of the old man brought him to his senses.
The belt wasn't shrinking. Dean was gaining weight.
It stood out to him now ever so clearly. His stomach, though not protuberous, was outwardly curved. His thighs seemed to have a layer of thickness to them, and his butt protruded a little farther than it did before. His arms and legs shared a few minor pounds of gain, and his face was tinged with weight, unnoticable to the untrained eye.
This is what the man spoke of. The belt held quick to the body, no matter what strain was put on it, so a comfortable fit would always be achieved. It was impossible, but Dean knew now to believe in the force of the belt.
Though he had gained a litle in weight, he gained a lot in insight. Indeed, this would make a great present to Jenny, one that maybe both of them could enjoy.
