Dr. Tracy had long lived in fear of contracting the mysterious new illness known as Whale Syndrome. With no known cure and a terrifying prognosis, ending up bloated beyond recognition and warehoused in cavernous hangars alongside other victims, she was determined to prepare for the worst. She had secretly developed a radical solution: an experimental serum designed to convert excess body fat into semen, used in a "revolutionary diet product", in a desperate attempt to redirect the grotesque weight gain into a more manageable transformation.

She didn’t know whether the serum would cure her or trap her in an endless cycle of growth and climax, but the alternative, becoming an immobile, swollen mass, was far more horrifying.

Then, one day at work in her laboratory, the inevitable struck.

It began as a strange tightness low in her belly, a flush of unnatural heat surging through her core. She staggered, breath hitching, as her limbs grew heavy, her skin tingling with a deep, primal pressure. Her lab coat strained at the seams, clinging to her rapidly swelling body as her curves thickened and ballooned outward. Her hips widened, her breasts jostled and filled, and her belly surged with soft, quivering mass. It was happening, faster than her worst projections.

She gasped, reaching desperately for her purse, where the vial waited, but her fingers were already thick, trembling, her arms wobbling with new, impossible weight. While she finally popped the vial and drink it, her reflection in a steel cabinet was almost unrecognizable, fleshy, plush, obscene.

And then the transformation shifted.

A bolt of liquid fire tore through her pelvis, and with it, a new organ erupted forth: her clit lengthened, stretched, hardened, morphing into a thick, pulsating shaft that throbbed with every heartbeat. It surged outward with impossible speed, extending inch by inch until it loomed nearly four feet in length, glistening and engorged. Her moans echoed off the walls, involuntary, hungry.

Below it, her balls swelled like rising moons, inflating with a tangible, pressurized fullness. It felt as though someone had hooked them up to a firehose of molten pleasure, filling her beyond any natural capacity. The skin stretched taut and flushed a deep, sensitive pink, every vein throbbing with arousal. Each pulse of growth made her shudder, her entire body trembling under the sheer erotic weight of the changes. Her fat had nearly stopped growing, but at the exchange of *another* growth.

Her groin ached with unbearable need. The tension in her loins was incandescent, electric, her nerves lit up with wild, orgasmic fire. She staggered back, gripping the edge of the lab bench, her legs wide to accommodate her swelling sac, now heavy and hot against her thighs. Her shaft twitched, leaking a thick, creamy bead of pre that clung to the floor in a warm splatter.

She bit down hard on her lower lip, teeth grinding together, her entire body taut like a bowstring. And then, at last, it hit.

The first orgasm exploded from her like a thunderclap. Her back arched violently as a jet of thick, steaming cum erupted from her tip, painting the wall in ropes of heat. Her moan was long, guttural, feral, her entire being seized in ecstasy as wave after wave of climax rocked her bloated, transformed body.

And it was only the beginning.

Dr Tracy preferred to transform her fat into cum than to become a fat whale
