A Lilligant, normal in every way...except for the resiliency of her skin, and her assets, both male and female. Sporting breasts with milk production that would put cows to shame, and hiding a member underneath her grass skirt so productive it makes doing everyday normal tasks difficult. More so because she only produces more milk and seed when exposed to the sun.

She tends to stay out of the sunlight, but Lily can't stop once she's growing. It takes a good release for her to not only stop producing, but also stop growing - and despite this, release is the one thing she's good at NOT doing. Rubber bands are a favorite, pinching her nipples shut so her tits fill, and keeping her cock plugged as it inflates to ridiculous degrees before unloading itself.

One thing unique about her is that her dick doesn't grow when she is producing, doesn't lengthen further than its full mast when it's aroused. It stays the same length no matter how many orgasms she's had; the only thing that does change is how full her urethra becomes. That, in itself, is unique: instead of a single vein running underneath her cock, it rather fills up a pocket around the member itself, with multiple points of entry into this pocket and one exit. It's still her urethra, even if not by name or a common function, and she loves filling it regardless; if it can be filled, she'll overburden it.

Such desire to test her elasticity led her to try something unique with her urges to fill herself. She loves testing so-called 'unbreakable' bands, so she fitted one on just underneath the flare of her cocktip. She never feared for any harm done to her when testing these bands, as they have all snapped before any lasting damage is done; the only thing she might complain about is a mark, but otherwise the pressure only brings pleasure to her. And so, with the tight black band secured, she began.

The first orgasm quickly led to the second, with cum starting to fill her urethra and not being able to escape. Her body was unusually good about not taking in anything that it expelled itself, even though she loved filling via external methods, so rather than the cum pooling up in her balls, it stayed in her urethra, beginning to balloon it up. With the first few spurts, only the underside seemed to fill as gravity took hold, looking like a regular dick bloating up. It was only when the underside reached the ground did things start picking up.

Lily's orgasms often led to her producing and expelling far more than any Lilligant should, to a hyper degree that defies logic. It's only when her body reaches a certain milestone does she stop, and clearly it hasn't stopped now. She reached her next climax without touching her member at all, as even now her bloated urethra was stretched enough to bring her to it without any additional sources of pleasure. Though, instead of being forced up, the top of her dick was bloating out, looking much like a balloon as the cocktip sunk in. Her urethra continued to take in cum, a veritable white beach ball attached to her figure.

But this was only the start. Her next climax was more intense, with the band holding tight, with as much pressure behind it to release even a single drop and yet it holds. Her urethra bloated up by the spurt, faster than before. A beanbag chair in size, a bed, an entire room - yet her cock was still the same length, it was only the urethra ballooning up with size. As more of the flesh stretched up and around, the cocktip itself was still firmly in place, with the only thing changing about it was the intense pulsing it was doing, as well as the urethra itself squeezing in from above. This created a little bit of a cave, where the only way out was through the little hole her urethra was ballooning up. Should she cum now and break the band, she'd have to push through that little hole.

And it's only getting smaller and farther away the more she cums and fills herself.

Picking up more speed, she dwarfs Olympic swimming pools, entire city blocks, growing faster with each spurt acting like its own climax. She thrusts her hips a little into the massive wall of white in front of her, still very much sane through her pleasure-wracked mind. The band was still intact, and despite her massive need to cum, all she could think about was growing even larger and stretching herself out even further.

The sun was doing its part by feeding her growth, as the bigger she got, the more she came, and the more she came, the bigger she got, leading to more space for the sun to hit. She could feel the waves of seed swish around inside, trying so hard to find a way out. The tiny escape route through the folds of the urethra was getting not just longer as the sphere grew, but also highly more pressurized as more was forced into it. Even if the band were to break now, it's not likely she'd be able to push her cum through it...and it all comes back down to her size just being too small to force it.

Still she came, and still she grew. The band was feeling even tighter with the pressure mounting, and as her urethral sphere reached mountains in size she could feel it start to give. Little by little, spurt by spurt, her exponentially increasing climaxes pushed more cum into her dick, the entirety of it starting to become visible from the planet from space. Each thrust of her hips pushed her that much higher into the euphoria of release, as she could tell it wouldn't be long until the band finally gave way.

Oceans of cum filled her urethra, her overproductive balls getting supercharged by the sun's rays. Thousands of miles of groaning, stretched-out flesh grew into the atmosphere, and within that churning sphere...a small snap. The band finally broke, and Lily's cock was all too eager to release its overburdened load.

Except...she couldn't. The small tunnel through her urethra had become so airtight that she couldn't even push any of the cum past her cocktip. An indescribably full feeling reverberated through her body as she bucked her hips, trying for any semblance of a release.

As she tried and tried to push any of the cum filling her out, she was going through even fiercer climaxes, her growth not stopping. It wasn't long before her swollen urethra had reached a planetary size, and an even shorter amount of time before she made even her own planet look tiny in comparison. Each of the spurts in her orgasms had by this point become long drawn out, lasting for minutes at a time before subsiding. Her white balls had even begun growing with seed at the end of her spurts, only to shrink back down under her leafy skirt once she had started her next push.

Lily beat on her urethra with her leafy hands, practically screaming. "Let me cum! Let me cum!" Yet as her growing cock bulged out further with each unstoppable climax, it was getting even more impossible. She could feel each and every pulse, each convulsion of her cock pushing cum up to the tip only for it to recede back in, stretching it as much as she could push it open.

"I need to cum! Now! Need to cum!"

Gravity was starting to affect the massive white sphere as it grew, bumping the moon itself. She shivered, feeling its weight push against her sensitive flesh, her urethra straining to push it away. In her struggle, it succeeded in making her cum a lot more from the pleasure it was giving her, thrashing her hips wildly as the smaller celestial object squeezed into the sphere, the elasticity slightly pushing it back only for it to grow and make it squeeze right back in.

The small air pockets inside the tunnel leading out of the sphere were compressed flat, leading to small pops happening on the inside of the sphere near Lily. With a little bit of air, she was able to push a little bit of cum out, but the pressure made it all go right back inside when she stopped cumming. Each spurt took longer for her to push out, and more to recover from. As she ended her spurts, her balls grew to mountainous sizes before her next climax emptied them, and then some.

"Nggyuuu...c-cum...! Have to...cum...!"

She became more strained as time went on, pushing harder and harder, hoping that she could force the cum through. But it was futile, as she passed the largest planet in size...and, in the next spurt, the sun. Groaning, all she could do was endure it all until she was finally, undeniably, unquestionably full.

She screamed, feeling more planets fall within the pull of her urethra and slam against it. Then, in the next spurt, catching the sun within its pull. The increased heat and eventual dissolution of the star and its plasmas against her bloating cock only served to overcharge her chlorophyll, now getting more sunlight than ever before.

Absorbing the star's energy, her orgasms grew exponentially stronger. And yet, she was nowhere close to full. The other planets in the solar system eventually fell into her urethra's orbit and smashed against it much like the planets before them.

"C-cum...cuuuum...c-can't...take...!"

The sound of her pushing an ever-growing amount of cum into her urethra was almost deafening. The massive white sphere was beginning to turn a very slight red hue as it swelled beyond the solar system. Still riding on the surge the star gave her, it was only five climaxes later, fueled entirely by her size and the star's energy and heat, that she reached the next closest star. Much like when she had grew into the first star, this next one provided another energy surge.

The euphoria was almost enough to knock her out. She screamed again, needing the release more than ever now. The duration of her gushes were now in the hours, needing several minutes of downtime - which her balls took in ample opportunity to grow to beyond star-sized before she felt her dick's unyielding need to release overwhelm her once more. She didn't need any stimulation that she wasn't already giving herself.

As the swollen urethra absorbed the heat and energy of the second star, she was only starting her next spurt of cum, increasing its power tenfold and pushing the sphere larger in the void of space. Compared to before, it didn't take until the end of her current climax for her to reach the next star. As she took in each one as it fizzled out against her bloated form, it grew redder, grew louder in its churning.

"P-please...! Need...neeeeeeeeed...!"

As she took in each star's heat, Lily's climaxes blended into each other. As one was finishing up, two more were already starting to take effect, her body working overtime to produce much more cum than she could ever let out. She thrust her hips with this savage need, her bursts of cum now just a constant stream. Yet no matter how hard she pushed, how hard she thrusted, how many stars she came in contact with...

No matter how big she got, no matter how much her body really wanted it...

No matter how much force was behind her orgasms, as they grew with each climax...

She'd never get the cum out. A fate of her own doing. Now she has to live with those consequences...

"C-can't...take it...!"

"St-stop...!"

"Don't...fill...!"

Taking in all the stars of the galaxy, as her urethra got more strained by the light year, more angered with each pulse. Then the next galaxy, and the next...still filling. Still growing. Making it more than just impossible for her to ever get the release she so desperately wants.

A small cracking sound. Lily jutted back to reality.

"No! No! My limit! My limit! C-cum! Have to cum! NOW!"

The universe strained to hold the massive white balloon. It inched bigger, slowing down as the skin became taut. All the planets she had picked up along the way no longer were sinking into the sphere. Each pulse made her shiver and shriek, and yet she still came.

She didn't slow down. Her urethra kept getting more and more backed up with seed. The universe was at capacity. She couldn't cum anymore - couldn't push any more inside.

Yet she did.

And when that universal barrier broke...a heat from outside poured in.

Lily felt the largest surge of cum yet fill her balls. She felt a thousand climaxes, perhaps more, building up as she took on the energy from the universe exploding outwards. She could feel her urethra's violent pulsating reach a fever pitch as the cum she was continuously filling it with had slowed to a trickle. Her buckling hips slowed down, back, forth...pulling back. She could feel it all building up. This was the last thrust she needed.

She needed to cum. NOW.
