Immediate reaction

With the restriction lifted and every other conditions being met, the eight balloons she had just tied up jumped up from the bed. Penny actually yelped at just how sudden it was. One moment, they were limp and unmoving, the very next one, the deflated toys had audibly puffed up to the size of a grape fruit and were now hovering a few feet above the ground, right in front of the only human in the room.

"Wooaaaah..." was all Penny could quietly come up with, the objects of her desire just floating ahead of her. Every tethered orb slowly grew bigger over time, loud huffes accompagnying their growth, as if invisibles entities were inflating them all for her. As Penny stretched a hand forward to touch the magical balloon, she had failed to notice more of them escaping the forgotten bag nearby, hovering out and inflating themselves around the room. Her fingers scraped the edge of the nearby balloon, which shoved itself against her palm, looking for a deeper touch as it surged slightly bigger. She was in heaven, this was everything she had dreamed of and more.

She fell forward with a surprised yelp towards her bed as a random balloon shoved itself against her back. She swiftly twisted herself on her back and only now did she notice the state of her bedroom with over two dozens bobbing party favors lazily hovering everywhere, the now empty plastic bag that used to contain her humble collection resting nearby. She was amazed, the dance happening around her giving a growing boost to her libido.

She felt ribbons twisting around both her knees and her shoulders. Looking around, the tied up fully inflated party balloons had divided themselves in pair of two, one for each of her appendage. They then tugged upwards. Not enough to lift the human, but hard enough to indicate to her they had tried to. They gave a few more pulls, all just as unsuccessful. In response, they all began hissing loudly and, to Penny's delight, bloated bigger, only stopping once they had doubled in size. The looner was panting at the show, the other balloons in the room bumping against her from time to time, sometimes slowly gliding against her smooth skin, as a reminder of their presence. She knew the balloons attached to her didn't really need to get bigger to lift her, they absolutely could be as buoyant as they wanted. They were doing this for her. They knew exactly what turned her on, and she loved it.

They tried tugging upwards again multiple time. The pull had grown massively and she sometimes barely felt the mattress under her, yet that still didn't seem to be enough. They relented their upwards pull as a long, drawn-out hiss filled the room. But for some reason, no balloons tied to her changed in volume, even with a squeaking noise rose in a loud crescendo.

"What--" she started to ask, only to be cut by the balloons holding onto her releasing what she could only describe as loud cartoonish boing sounds, all eight of them doubling once more in size in the blink of an eye. Each of them were now half her size, and she marveled at their shiny bodies. Those were rated as simple party balloons, they should have never, under normal circumstances, been able to get much bigger than her own head! Yet, as she slowly came to the full realization that all her wish were absolutely coming through, the toys resumed their upwards pull. This time, when they reached the end of their tethers, the magical toys effortlessly lifted their passenger in the air, making her squirm in delight. She was surprised at how comfortable the scenario was despite only being lifted by a few thin ribbons, she was half expecting those to cut deeply into her skin.

She felt them bounce against the room's ceiling a few seconds later, stopping her ascent in a jolt. That singular jolt made her gasp loudly. She couldn't hold back anymore, and a hand darted between her legs to take care of her leaking faucet. A random party-sized balloon had been faster than her though, which shoved itself forcefully right against her moist privates, her hand colliding with its stretched rubber skin instead. She tried to push it away or to hump her hips against it, but any attempt to stimulate herself through it were negated, the balloon refusing to yield any leverage. "Come on, I need it," she pleaded.

She felt herself getting gently lowered, the powerful balloon overhead somehow losing their upward strength. Soon after, the blue haired girl felt herself sinking on top of something surprisingly squishy. She rapidly realized that, unbeknownst to her, a singular purple balloon had at some point inflated itself in a rolling pin shape, longer and wider than she herself was. With a comfortable amount of give, the latex lovingly hugged her from behind. She was hovering in place while lying down on that new massive balloon, the other one attached to her now lazily floated around, releasing a melody of nicely inflated latex bumping against each other and, sometimes, herself.

Penny loved every single second of this. She wanted more. She needed more. She was a panting, moaning mess, her legs and her arms kept rubbing against the silky smooth balloon under her, and yet the balloons around her had barely done anything other than tease her at this point. Her mind was checking out, her ecstasy going through the roof. "Dominate me..." she pleaded, whispered to her entourage.

Penny felt herself slowly rising once more with the help of her new purple latex bed. The balloons tied to her collided with the ceiling and began bunching together right above her as the girl's ascent proceeded. She began panting more and more as the balloons overhead got closer, whispering a "yes" at various interval until, at long last, she felt herself getting sandwitched between her impromptu bed and the heavenly colorful cloud. "Yeeeeesss~..." The balloon underneath her only stopped once its rider was so firmly squished with its friends overhead that Penny couldn't move anymore.

With every limbs immobilized by the balloons, the one still pressing against her sex took that moment to begin twisting and grinding itself against her, making her moan loudly in surprise. With how wet she was, the friction was gone in an instant, making the inflated latex's sexual massage just divine. The human couldn't move an inch, but the balloon between her legs definitely didn't have that restriction.

"Mooooore..." she tried to formulate, which the party toys understood the meaning. She felt the orb between her legs expanding slightly just as the mouthpiece found her clit. Her eyes became unfocused as her brain began shutting down, right as she felt a nice suction applied to her most sensitive button.

"O-oh god, so-o good~ You're a-all awesoooOOOHH~!" Her speech was interrupted by a lustful moan when the balloon humping against her pussy remolded itself and began expanding its latex between her pussy lips. It had no issues invading and spreading the sensual cavity apart, to Penny's delight. The invading appendage kept expanding bigger and longer, reaching depths the girl had never experienced before. She felt so full.

"You're awesome!" she screeched. "I don't think I can--" she began, but interrupted herself when she felt every balloon on the ceiling suddenly surge an inch or two bigger with an audible huff. The one she felt the most was the one that had penetrated her, her vagina stretched to its limit and the latex pressing itself perfectly against the entire hole's moist walls.

"Oh... oh God..." she squeaked. The vagina balloon tried to wobble, not that it did much with how tightly she filled the girl, but she absolutely could feel its attempt. "I... I'm gonna--" She felt the balloon acting as her mattress wobbling and rolling in waves under her, the mouthpiece of the one between her legs pinching and sucking her clit strongly and the latex trapped inside her pussy vibrating powerfully. "CUMMIIIIIING~!!!"

Penny screeched like a banshee, the **** finally tipping her over the edge. She felt her muscles locks down and her pussy trying to milk the balloon trapped in its fold. The balloons never stopped and kept caressing and playing with the orgasming girl who was now an absolute moaning mess in their grasp. She kept moaning, her orgasm lasting much longer than any she's ever had before.

At last, she began to calm down, and so did the balloons playing with her. They lowered themselves, the long banner balloon landing back on the bed while the balloons tied to her limbs detached themselves and floated back towards the ceiling.

Everything went still, the only sound in the room being the post-orgasmic girl trying to catch her breath after the greatest orgasm of her life. Her hazy gaze scouted her bedroom, seeing balloons against the ceiling and the floor, every single toy blown up much bigger than their rated sizes. She released a small, tired giggle. "Greatest moment of my life..." she whispered as she sent her head to rest back against her airy impromptu bed.
