The warm summer sun shined brightly in the sky, its soothing rays coating the fair complextion of the twin tailed girl as she sipped on her cool drink. A light rustling to her side made her look over as she lifted the rim of her sun hat to see her girlfriend going through a box of randon pool items. "What's up babe?" she called out as her blonde lover sighed and brushed her hair back.
"I can't find the inflatable pool toy." She replied which made Stacy giggle lightly as she set her drink down and got up. Swaying her wide hips to tease her lover, she hugged Crystal from behind and looked over her shoulder, a task that required her to stand on her tip toes.
"Hmm, you're right. I guess... you'll have to do." with a grin she poked a button on Crystal's necklace, making the blonde flinch but giggle. "Oh you naughty girl..." she said as she turned her head so she could kiss Stacy on the lips, her hands cupping Stacy's who was rubbing her skin lightly. Slowly the peach skin began to turn blue as little wings formed out of her back and horns grew up top.
"Me? Naughty? Says the demon girl." Stacy stated back with a giggle as she gave Crystal a deep kiss, her hands squeezing the demon girl's chest as Stacy began to blow air into Crystal's mouth, making the demon shiver as Stacy's fingers spread out as the bust she was a holding was beginning to grow against her palms, gaining a little bounce.
Crystal's thighs rubbed together as air hissed thrrough her form, plumping up her thighs which squeaked like rubber as they rubbed together. her bottom jiggled and swayed as it inflated and bumped against Stacy's thighs which just made the girl more tempted to inflate her lover to even larger sizes.
As their passionate kiss continued a sudden gasp escaped Crystal's lips as Stacy's hand had moved down and began to rub against her lover's sensitive area. About to protest, she was silenced as Stacy pressed her lips against her again, blowing harder as the demon girl began to grow faster. Her bikini top strained to contain her swelling mounds as they bounced and grew to the size of her head but kept going. Her bikini bottoms dug into her skin and sank into the bottom cleavage as it began to form a thong, the thighs now rubbing together harder which heated her down below even more.
The kiss ended unexpectedly as Crystal looked around, "W-what? why did you stop?" She asked, then realized why as she had to look down to see Stacy, at least three heads taller than her lover. "Heehee, you're a little too tall for me to reach up." Stacy replied as Crystal blushed and began to bend over, displaying a deep cleavage for her love as she almost kissed Stacy again but soft fingers pressed back against her lips.
"Not that way Love, not yet any way." Grinning wickedly, Stacy lifted something from the pool box that made Crystal's eyes widen as she smiled, seeing the bike pump they use to inflate the pool toys. Knowing exactly what to do, Crystal turned around and swayed her huge soft cheeks in front of Stacy as her demon tail dangled in her face.
Grabbing hold of the tail, Stacy slid her hand down its length until she came across the valve like tip at the end of it. Opening it, a hint of air came out but the opening was soon plugged by the air hose of the bike pump. Moaning in anticipation, Crystal began to softly massage her own bust as the handle of the pump rose and then fell, a rush of air flowing into Crystal, causing her basketball sized butt cheeks to inflate even larger as the demon moaned.
The handle rose and fell more and more, the demoness gasping and panting as her breasts grew in her hands, the bikini cups becoming less and less effective as they squeezed her breasts and were soon only covering her nipples. Her toes clenched as her thighs rubbed harder to pleasure her rising need as a slightly dampness formed in her bikini bottoms as almost nothing was hidden with how spread thin the fabric was.
"Mm... love... give me more..." Crystal begged as she turned to face Stacy but gasped as her steps were lighter, able to make her bounce with each step. The concept appealing to her, she took light bounces until as enough air was placed inside her she was able to float lightly, her small wings flapping lightly. "Stacy! I'm floating!" She called out happily as she floated towards Stacy and gently cupped her head in her larger hands.
At least 9 feet tall, the demoness got closer to Stacy as her lips pressed against her love's who welcome them warmly, kissing Crystal as she pumped more air into her. As Crystal's body stretched and grew, the human began breathing more air into Crystal, increasing the process even further as her lover truly began to inflate.
Her wings grew longer and stronger, flapping with more excitement as her tail also grew. There were loud snaps as her bikini was destroyed by her unstoppable body, leaving her bare for her love who took in the sight of Crystal's medicine ball sized curves and merely blew more and more.
Getting a little winded, Stacy had to stop but smiled as her lover hugged her close to her 12 foot body, snuggling against her cleavage as her added weight made Crystal return to Earth. When her feet touched the ground Crystal fell back intentionally as there was enough air to make the fall gentle as her body landed on the pools surface, making her moan as the cool water touched her warm flesh.
Giggling, Stacy cuddled her huge lover as they kissed gently, floating calmly on the pool's surface. "See, we dont need a pool toy. As long as we have each other, we'll always have something nice and soft to cuddle and play with. And the best part is..." Kissing Crystal once more, air poured into Crystal which surprise the demon. "No matter how much I do it, you'll only get bigger and bigger." She teased as the two resumed their fun as Crystal's body began to cover more of the pool.
