Arch would gurgle a bit, coughing and shivering as the slime expanded inside of him, bloating up every inch of his body with cold, clammy rolls of pseudo-fat, to distracted by the overwhelming feeling of sudden weight to hear the wooden board being extended, and the slow, fatty waddling of the lady who had waved hello to him. She unhooked his chains, pulling him to a kneeling position on the platform with repetitive ease, hefting his almost-limp body by the shoulders.
Slowly she would walk him down the hallway out of the room, too distracted with the building feeling of pressure and nausea in his stomach to protest, or even to remember to open up his eyes and try to map out an escape. Stomach growing softer and rounder between his fingers, stumbling down the hallways and around corners, guided by the cold, clammy hands of his bloated tour-guide
By the time the umbreon could think to blink his eyes open, he was forcefully sat down on a brickwork ledge, a pair of hands on his shoulders pressing him down. He let his hands explore his gut and thighs, audibly gurgling and visibly growing inside of him, filled with thick, green, cold ooze that seemed to slosh across his body no matter where he was pressing. He vaguely registered the feeling of his thighs spreading further into his pants the more he pressed on his gut, forcing the slime to another part of him.
He would try again to speak, but the cold taste of sweetness rushed out of his throat; sputtering out several globs of ooze before he could clamp his mouth shut, the liquid splashing into the massive drain situated beneath him. He quickly covered his mouth with a hand, cheeks swelling up as the torrent tried to escape, his entire body swelling like a balloon in anticipation.
The hands on his shoulders would slide down to his gut, wrapping around his front and pulling down, the gallons of sludge forming inside of him suddenly being pushed back out of him. Unable to keep it down as he suddenly spat out several large globs of the stuff; far more than he had accidentally choked down from being dunked in a pond. With it came the feeling of relief, his hand left hovering infront of his face as he let the slime spill out of him, the growth having ceased.
His mind grew hazy for a moment, teetering on the edge and being held back only by the crushing hug he was trapped in. Despite being near-frozen from the inside, a pleasant buzzing was starting to spread from the back of his throat, digging deeper into his body and twisting into his limbs with a foreign pleasure from the release of pressure, his shoulders finally relaxing.
By the time he was spitting out the last few drops of the substance, his arms were left dangling at his sides, having bloated up with more of the goo; and he hadn’t even shrunk down despite the sheer amount he just had pushed out of him. His hazy mind still felt the women hugging him from behind in a soft, clammy embrace. He was exhausted, and tired, even her strange pillow of a gut felt good enough to fall asleep into…
