Gush’s effects are somewhat unpredictable, but the two largest are a commencement of high levels of lactation and expansion of mammary glands and associated tissues, including nerves. Additionally, one of the most sought-after hallmarks of the drug is a sudden and total obsession with one’s own breasts, focused around the expression of lactic fluids and stimulation of the nipples. Other common effects are catalogued below:
- Increased libido. Some research claims that every dose brings with it an increase in libido, few scientists are willing to study such an outrageously illegal substance.
- Increase in ability to manufacture milk (or racially appropriate nutrient solution), resulting in a need for more frequent draining.
- Conversion of fatty tissues into additional lactic storage glands.
- (Rare) Growth of additional nipples.
Originally created to bolster milk production in mothers with difficulty expressing milk (or a racially-appropriate nutrient solution), the formula that would one day become “Gush” was found to be entirely too effective, swelling mammary glands to enormous proportions in a matter of minutes, triggering pleasure hormone cascades potent enough to bring a user to her (or his) knees.
The original test subjects initially expressed only excitement and pleasure at their enhanced physiques, seemingly fascinated by the almost boundless, liquid weight contained within their chests. Many were observed heedlessly and repeatedly tugging upon their nipples, even after expressing every single drop. Only after a full fifteen minutes of such activity did the subjects, terran, ausar, and kaithrit alike, come to their senses, surprised and embarrassed by what they had done.
While some growth in mammary size is an expected part of inducing lactation, this level of tissue expansion proved shocking to the test subjects. Some expressed concern that it would be difficult to for society to take their top-heavy forms seriously. Others worried of back pain. TamaniCorp provided the necessary spinal and back augmentation treatments free of charge, of course, but the bulk expressed pleasure at the changes. Breast augmentation is readily available yet still an expense many choose not to pay. To get such an enhancement for free, as part of a study, was quite a windfall.
Research budgets were doubled on the back of this unconventional success. Bureaucrats figured they could branch into another market. Gush would be cheaper than many methods of genetic alteration and less invasive than surgeries. A minor medical advance for expectant mothers was going to make them trillions the galaxy over, or so they thought.
When TamaniCorp opened its doors to applications for the second trial, it found itself flooded with requests from the initial group. To a woman, they had decided that they could do with bigger, milkier bosoms - besides, they had yet to test multiple dosages, right?
The company begrudgingly broadened the scope to include two parallel studies: the first, a larger version of the initial trial, and the second, a test to determine the safety of repeated treatments. Both would use an improved synthesis of the formula. The scientists behind Gush were determined to eliminate the bliss cascade that it set off in its users.
Their efforts were for naught. The altered formula seemed even worse than their initial recipe. Subjects were recorded staring at their breasts as they expanded, their gazes increasingly vacant as their hands began to roam across their growing, increasingly fluid-filled busts. Those able to unerringly sought out their follow test subjects, polishing their own skin and fur with glistening alabaster, collapsing into puddles of engorged teats, searching lips, and slippery skin.
Attempts to restore order were made, but the brave scientists who dared enter soon found themselves buried in breasts and soaked, blushing flesh, hard nipples thrust into their mouths until milk and slick handjobs transformed their protests into pleased gurgles.
An hour later, bodies were disentangled, mops were brought out in bulk, and dazed scientists logged notes from above overfull bellies.
The repeat trial, held in another facility, fared little better. Subjects were handed their doses in dermis-penetrating spraypens before the order to abandon the study came through. No one thought twice about the slightly elevated blood pressure and heart rate of the volunteers - both were well within acceptable limits, and if anyone smelled drenched, excited panties, they certainly neglected to mention it.
Leaked by an unscrupulous network technician, the bootleg holo-recordings of the ensuing orgy went on to become one of the most infamous videos on the extranet, downloaded at least 650 million times by conservative estimates. Well-endowed women quivered and came to the sensation of their breasts ballooning into proper, milk-oozing tits, their eyes smoky with unrepentant need. Curvy mothers transformed into gushing sexpots over-endowed enough to pursue a career in ultraporn. No matter how unique or distinct their race, personality, or appearance, titanic, fluid-squirting boobs became the constant.
One-way mirrors became white and opaque under a creamy deluge. Carpets became off-white sponges. What little furniture was available in the testing area was irrevocably stained with the sexual secretions of a half-dozen races. Ecstatic moans and throaty groans filled over two full hours of audio logs while the sight of orgasmically gyrating, milk-squirting bodies were lovingly recorded in full, three-dimensional detail.
The Gush project was cancelled and the chemical formula deemed unfit for further investigation, to be locked away in secure archives with thousands of other rejected compounds, many far more mundane. The early testers were forced to go home bigger and milkier, their enhanced bodies craving more titty-fueled licentiousness.
It would have ended there too, if the formula hadn’t been leaked along with the incident footage. Gush is too easy to synthesize to be kept from masses, and anywhere that illegal drugs or transformatives are sold, Gush will inevitably be found.
