When Owain opened his eyes, he was staring into a dark abyss, his mind still groggy. Was he dreaming?
His belt felt a little snug, perhaps put on a tad too tight this morning.
His hands moved to adjust it to something more comfortable.
But, getting to his belt, his hands slid past a weird object and it startled him upon looking down.
His belly was forcing its way outwards from his form. His previous physique was already gone in favour of a small gut, continually expanding.
He held his stomach with his palms, as if trying to keep it contained. But it was working as well as his outfit's efforts, for which the gap down the middle of his torso had forced the two sides of the outfit further and further back, forming tears.
"Ack!" Owain yelped in pain as his belt began to really dig into him. He attempted to fumble with the constrictor, to relieve himself of the pressure but it was too late, as his now sizeable gut cast an impassable shade over his lower body.
But then, SNAP! Oh, what a relief. The belt, designed for Owain's skinnier frame, had split and landed on the floor beside him.
The growth slowed and then stopped. Leaving Owain with a sigh of relief and a very large and heavy gut.
It was if someone had chained him and fed him relentlessly for hours on end.
"A nice start, but shouldn't we make it bigger?" A strange voice cam from nearby.
"Who...?" Owain looked about to see another man, one who looked eerily similar to himself.
"I'm you, an inner you, an inner you awoken by the spell." He came over and began to caress Owain's belly, "And we're going to make this bigger."
"What? No!"
"Oh? But I thought you liked this feeling."
"I don't like..." His words trailed off as he looked at his inner self and then back to your stomach.
"Don't you like this feeling?" He grinned deviously.
"I-I like this feeling..." The bloated original slurred.
"Wouldn't it be great to have a large belly all of our own?"
"Yes..." Owain's personality began to shine back through, but with a noticeable change, "Yes, I, Owain Dark, will have the largest, heaviest, most breath-taking belly in Ylisse! I shall devote myself, day and night, not to the sword but to the belly, forcing delicious morsels down my throat in hopes to be so big I cannot even move!"
"Good boy. You'll be returned to reality, shortly. Then I will guide you on your quest..."
