Neko Milk Overflow (Patreon)

She pads down the hallway in her pink-and-white striped top and tiny blue shorts, black tail swaying behind her while the little bows on her cat ears bounce with each step. She is already ridiculously top-heavy, the striped fabric pulled tight across her chest, but tonight her boyfriend wants to see just how much bigger she can get. Waiting for her is the milk bowl he quietly spiked with the potent cow hormone pills they picked for the roleplay. She kneels, drinks it all, and for a few seconds nothing happens.

Then her chest starts to feel warm.

The warmth quickly turns into a deep, pulsing pressure. Her breathing catches as the first damp spots bloom across her shirt. Warm milk begins to seep through the thin cotton, and she looks down in surprise, tugging the hem lower as if she can somehow keep everything contained. It only makes the strain more obvious. Her breasts are getting heavier by the second, swelling outward against the fabric, stretching the stripes wider and wider. The material tightens, seams pulling hard across the growing curves until the shirt finally gives with a sharp, wet rip. Full, leaking tits spill free, already bigger than they were minutes ago, milk running in thin streams down the undersides.

She tries to hurry to the bed, but every step is harder than the last. Her chest sways heavily in front of her, growing faster than she can adjust to the weight. Milk drips steadily while she awkwardly braces the swelling mass with her arms and stumbles the final few feet. She drops onto the mattress with a relieved gasp, convinced the strange rush is finally dying down.

For a moment, it does.

Then another wave hits.

Her eyes widen as a deeper surge of fullness rolls through her. Her breasts begin swelling again, spreading across the mattress as they grow heavier, rounder, and wider, the skin stretching shiny and taut. She tries to push herself upright, but the expanding weight keeps settling over her, pinning her deeper into the bed. Soon they are so enormous she can barely move beneath them, surrounded by soft, leaking mass that continues to slowly swell even after she has completely run out of room. She is trapped, face half-buried between two gigantic, dripping orbs.

From the foot of the bed her boyfriend strokes himself, watching her struggle under the weight of her own chest. He comes hard, thick ropes splattering across the pale, stretched skin, mixing with the milk already coating her. She cranes her neck as far as the massive tits will allow, tongue out, and licks a long stripe of cum from the underside of one swollen breast. Then she looks up at him from between the gigantic curves, flushed, breathless, and overwhelmed—tail giving a weak flick against the sheets—already giving him that familiar needy look that says she wants more.
