The mountain air was crisp and cool, the scent of pine and fresh soil carried gently on the wind. Their tent was pitched near a slow-moving river that sparkled with sunlight, and the whole forest seemed to sigh in peace around them.
Mirio stretched his arms and inhaled deeply. "This was a good idea."
Lily bobbed beside him in her usual form—slightly jiggly, wearing a hoodie and shorts that barely clung to her translucent hips. Her tentacle-hair swayed behind her like gentle steam. She had been calm all morning, clinging to his arm while they set up their cozy tent and unpacked marshmallows and a sleeping bag big enough for the both of them.
And then, while Mirio gathered firewood, she wandered to the river.
What he didn't see was Lily crouching at the edge of the water, dipping her hands in with a delighted squish. The river's current tickled her core, cool and dense with glacial purity.
Her glow pulsed.
Her skin rippled.
And then, instinctively, she absorbed it.
Every drop she pulled into herself made her core pulse brighter. Her body grew… and grew… and grew.
By the time Mirio returned to the tent, arms full of firewood, the sun had dipped low and the entire tent bulged like it was trying to give birth to a refrigerator.
"What the hell…?" he muttered, dropping the wood.
Inside the tent, it was hot.
Wet.
And tight.
He crawled in carefully, flashlight flickering.
Then stopped.
Completely and absolutely smothered against the far wall, he saw her.
Lily—except not quite.
She was massive.
Her height had nearly doubled, but it wasn't just her height—her proportions had shifted too. Her hips were wide, thick enough to fill half the tent. Her thighs were smooth and heavy, spread outward as if they'd fused with the fabric. Her breasts were absolutely enormous, wobbling with every breath, practically glowing through her transparent skin with the sheer amount of water inside them. Each one was nearly the size of Mirio's whole torso.
Her long, now-silky hair fell across her shoulders in thick, coiling strands, steam curling off her cheeks. Her lips were fuller, and she had a sleepy, sultry look in her eyes.
"Hubby~," she purred, her voice deeper, almost maternal.
He blinked. "L-Lily?! What happened—?!"
She giggled and rolled slightly onto her side.
Her butt slammed into him with the force of a small mattress.
"MPH—!"
Mirio vanished beneath one soft, wet cheek.
Her hips jiggled with a slow, deliberate wobble as she twisted her upper body toward him, breasts wobbling against the inner walls of the tent like balloons in slow motion. Her core pulsed. The air filled with her warm, sweet scent.
"Mmnn… mountain water's strong," she moaned. "Made me all… big and squishy for my good boy~"
She reached back with one thick thigh and gently squeezed him between her knees, dragging his face up from under her ass.
He gasped. "I can't breathe under there!"
"You can now," she purred, winking.
Then slid her thighs up his face.
He sputtered as her soft, slick skin rubbed along his cheeks, her thighs pressing in gently on either side of his head. Her slime was warm now, almost heated, and her body molded around him like a custom-made pillow.
"L-Lily, this isn't—!"
She silenced him with a single finger to the lips.
"Shhh. Good boys relax when their slime wife wants to cuddle."
She leaned forward, her massive breasts dragging across his stomach and settling squarely onto his lap. They wobbled into place with a slow, bouncing slosh, the heat from them instantly soaking through his pants.
He froze.
Her slime slid up his shirt, coiling gently around his ribs.
"You look so tiny right now, hubby," she cooed, rubbing her cheek against his. "Wanna just wrap you up and keep you in here. Squeeze you between my hips… nuzzle your face with my thighs… rock you to sleep with my boobs…"
"Lily—!"
Her breasts bounced once—deliberately.
He felt it.
She leaned in again, brushing her lips to his ear. "Say it, hubby."
"S-Say what?!"
"Say you're my good boy."
His ears turned red.
"I—"
She rolled her hips slightly, her lower half sloshing forward and pinning his legs. Her breasts shifted, massaging his lap without even trying. Her inner gel rippled.
"Say it," she whispered again.
"I'm—your—good boy—"
"Mmmmnnghh," she moaned, full-body trembling. "That's it. That's my hubby. My cute, red-faced, pinned-under-my-ass good boy~"
She kissed him again, this time deep and long, her lips warm, her tongue like soft, flavored syrup. Her tentacle-hair wrapped around his shoulders, and she pulled him deeper into her embrace.
When she finally let go, Mirio gasped for air, face flushed, body completely limp.
"Lily," he panted, "You're crushing me…"
She blinked, then shifted just enough to lift her butt off his torso.
The bounce from it alone nearly KO'd him.
"…Let's never go near mountain rivers again," he wheezed.
She giggled and nuzzled his face again.
"Only if my good boy says please."
