"Mel, let's just say, I've got some experience with being in your position."
"Well, I figured if you came up with the idea, you probably tried it yourself," Melissa agreed.
"But of course! Right now, you're puny compared to how big I've inflated myself," Carly stated matter-of-factly as she strutted around the Melissa's front. "Let me impart some wisdom upon you; the further you stretch your skin, the more sensitive it becomes."
Melissa admired Carla's ass as she came into view. Round and firm, it looked glorious, even encapsulated in the soft white fabric that concealed it. Returning her attention back to the conversation, she replied. "So you're saying that..."
"Exactly, my bloated beauty. The bigger you get, the bigger the sensations get." Carla bent over to pick up the hose on the floor, her ass pressing tightly against her panties. "I'm thinking my balloon could do with quite a bit more helium," she said as she turned to face Melissa, her pendulous breasts swaying slightly. "Open wide, babe. You're about to be upgraded from balloon to blimp!"
Melissa couldn't even blink before she felt the tube being forced between her lips. In an instant she felt the helium rush into her mouth at an alarmingly fast pace. Carla must have opened the valve completely this time. Every second, Mel's exaggerated features were becoming even more exaggerated. Her massive stomach was bloating inches at a time, her breasts in a race to keep up.
"Yes..." Carla cooed. "I love watching you grow." She pushed Melissa back, rolling her off her stomach and on to her ass. Arms spread wide, she hugged Mel's bloating belly, feeling it grow bigger and wider. "Ohhhhh..." she moaned. "I'm gonna make you so HUGE !
Melissa was beginning to really feel huge, and her body was reflecting it. As she continued to fill, her whole body began to round out. Her arms and legs were forced akimbo as she felt her crotch push down towards the floor. Her features were slowly merging as she continued growing, now as wide as she was tall. Her panties stretched with her, the waistband holding tight against her body as the black cotton pressed tightly against her.
Carla licked her lips she saw Mel's inflated pussy pressing tightly against her panties. That tight asian snatch was ripe for a good finger fuck, and as Mel's arms and legs were being absorbed into her frame, there was no way she could resist her.
Melissa felt immense pressure all through her body Aside from the spheres that were her breasts, her whole body was a globe, filling evenly now as the helium continued to invade her. Suddenly, she felt herself being rolled forward, her head stopping parallel with the ground. She dare not speak, not wanting to lose any of the helium, but still wondered why Carla had rolled her around like that.
Carla was fixated on the mound jutting out under Mel's stretched panties. She quickly pulled the black fabric aside, revealing the asian's tight, wet pussy. With a devilish smile, she gently traced her finger around the bloated lips, teasing the girl's clit occasionally. Judging from the moans she was hearing, she decided to take it a bit further, plunging two fingers deep into the waiting hole. Slowly she pushed her fingers in and out, feeling just how tight the girl really was.
As soon as the fingers invaded the cavity, Mel's senses erupted with pleasure. Each thrust of Carla's fingers was tighter than the last as her inflating body squeezed them harder by the second. Her sensitivity grew as she did, and the feeling was mounting as she inflated bigger and bigger.
Carla switched gears, knowing the big finish was fast approaching. Pulling out her wet fingers, she switched to using her tongue, licking and teasing the ballooned clit and plunging in and out the soaked box.
Mel was now at least six feet wide, her moans growing louder as she grew. This was it. She was ready to explode...
Carla knew it was about to happen, and she couldn't let up. She licked and sucked with vigor as Melissa reached climax. The moment she heard Mel scream, Carla felt the girl cumming, and she ended up...
