"By the way, if he can do that..." Rebecca's voice boomed outside. There was a pause, and a breath, while she chewed some more of the noodles in her plate. Blake could practically hear them oozing downwards into her gut, where they churned wildly. He always thought of her as a little more proper than that... Maybe it was just the terror of it all.
Claire's voice, however, boomed even louder in his ears. "What's on your mind?"
Rebecca thought for a minute. "With all that magic your son can do, can't he get out on his own?"
Blake felt himself sink in the mass of abdominal tissue. "Don't you think I would've tried already?" He felt ready to punch some of it - but his range of motion was limited, and it'd probably punch back anyway.
Claire poked at his spot, muffling him more. "How rude!"
Rebecca shrugged. "That's too bad. I was thinking my own tummy has problems after big meals like this. Was wondering if I could borrow him."
Blake, gasping for air beneath the finger, choked out: "W-well, there's a way... I could transfer there directly... B-but mom just said she needed me?"
Claire put her hands on her hips. "I'm feeling much better. Why don't you visit your Aunt Becky's belly? Come on. Do the spell."
Blake sighed, and began chanting as best he could with the pressure of his mother's gut - and her companion's eyes. "Projection from this form, shaped to a new norm, soul extraction, evasive action."
He felt himself leaving the stomach mass, floating in the air - unable to control his motions. The shape of Rebecca's abdomen came into view. The navel was exposed - with an abdominal wall even more toned than his mom's (quite healthy) stomach. She wore a tank top, and jeans that sat on the restaurant's outdoor seat, transitioning into a jean jacket.
And soon enough, all of that disappeared - as he sunk into the mass. His biomatter and soul were now one with Rebecca's.
And it was TIGHT!
She was always rather active, but the pink muscle walls around her felt more like barriers of solid concrete, with none of the give that Claire's had. It was hard to the touch, squeezing where Blake's shoulders would've been. And the smell of sweat kept searing at his senses, giving a constant burn. This was the closest thing to hell he'd been into! Instantly, Blake regretting going along with it - but he had no more breath to protest.
A hard PAT from outside cemented his place. He squirmed in the millimeter of space provided. "Perfect fit! Enjoy~!"
The last bites and subjects of the meal continued. Blake could barely adjust to hearing the crunches and gurgles. When they finally subsided, he was rocked back and forth. Claire only bid him a muffled, distant "goodbye!" before his new owner was on the path home.
"When I'm back at my place," Rebecca mused to herself...
