Gretchen (AI assisted) (multicock) (tail) (other multi suff)

Story by booobp

Again, like my other post idk how AI content is received. I will continue this cause I have ideas for a few more parts. I hope the formatting isn't too messed up with the spoiler tag, cause viewing the code it's borked.  I forgot how to tag posts, so more tags here (excessive cum) (future incest) (domination) (idk what else, i'll tag as i come up with it, i have 4 parts so far with ideas for 2 more)

Part 1

Gretchen stirred awake in the dim light of her bedroom, the soft hum of the city outside filtering through the curtains. At 25, she had mastered the art of blending into the background—a tall, bespectacled librarian with a penchant for oversized sweaters and loose skirts that swallowed her frame. No one suspected the secrets she harbored beneath those layers. She was the only one of her kind, a genetic anomaly that made her body a labyrinth of hidden wonders and burdens. Stretching her upper arms first, she carefully unfurled the lower pair from where they tucked against her sides, hidden all night under her baggy nightshirt. Her 6.5-foot frame uncoiled like a cat, her soft muscles rippling naturally without effort.

At 6:30 a.m. the city was still quiet enough that her soft gasps wouldn’t carry through the thin apartment walls. She locked the bathroom door, stripped, and stood naked under the harsh fluorescent light. Her four breasts hung heavy and taut, veins faintly visible beneath pale skin, already leaking thin trails of milk that ran down the soft curves of her abdomen.

She didn’t bother with gentle coaxing anymore.

Her upper hands gripped the top pair hard, fingers sinking into yielding flesh while her thumbs and forefingers pinched the bases of those four-inch nipples—already swollen and rigid from overnight pressure. The lower pair of hands seized the second set of breasts even more roughly, twisting and pulling downward in long, deliberate strokes. Milk sprayed in thick white arcs, striking the porcelain sink with wet slaps. The sound echoed obscenely in the small tiled room. Each tug sent jolts of raw pleasure-pain straight to her core; her long nipples throbbed, lengthening further until they jutted nearly five inches, dark and glistening.

She moaned—low, broken, unable to stay silent—and her prehensile tail snapped free from her waist like a whip. The muscular length coiled twice around her own thigh for leverage, then drove upward. Its dexterous tip—thicker than three fingers—forced its way between her labia, spearing into the left vagina while the right one clenched hungrily around nothing. She rocked forward, fucking herself on her own tail in short, brutal thrusts while she milked harder. Milk gushed in rhythmic pulses now, nearly two liters flooding the sink in under ten minutes. Her abs flexed visibly, the six massive internal testes shifting behind them, already swelling with fresh pressure.

When the flow finally slowed, she was trembling, nipples raw and dripping, vaginas slick and pulsing. She didn’t stop.

One upper hand slid down to fist both eight-inch clits—now fully engorged and ridged like miniature cocks—while a lower hand reached back to spread her ass cheeks. Her tail withdrew from her left passage with a wet pop, only to plunge immediately into the right one, deeper this time, curling to press against the sensitive front wall. Gretchen’s head fell forward, glasses fogging. She bit her own forearm to muffle the keening sound that tore out of her as she came the first time of the day: a sharp, almost painful contraction that forced a thick rope of her own slick to drip onto the tile.

She wasn’t finished.

Breathing ragged, she willed her twin penises to emerge.

They didn’t slide out delicately. They surged—eighteen inches of girthy, veined flesh erupting from each soaked vagina in one violent pulse. The sudden stretch made her gasp, knees buckling. Each shaft was already leaking, the slit weeping clear precum that dangled in long glistening strands. The smell hit her instantly: thick, animal, overwhelmingly virile, like overheated iron and musk and salt.

Gretchen dropped to all fours on the bathmat. Her four arms worked in frantic concert. Upper right stroked the left penis from root to tip in long, squeezing pulls; upper left did the same to the right shaft. Lower right wrapped around both bases, milking upward in counter-rhythm while lower left cupped and tugged her heavy scrotum—though no external sac existed, she could feel the six internal testes churning, impossibly full.

Her tail joined the assault. It wrapped twice around the middle of the left penis
