The Voluptuous Neighbor Possessed by an Alien Studying Reproduction on Earth

Chapter 1: An Ordinary Afternoon and a Hidden Gaze

The afternoon sun dripped like melted honey over the asphalt of the “Sunshine Gardens” community. Emily Harper set the last carton of milk into the fridge, her full breasts swaying gently with the motion, her white tank top faintly damp with sweat and clinging to her skin, outlining seductive curves. At thirty-five, divorced and living alone, she worked remotely as a designer and occasionally taught yoga at the community center. Neighbors called her “warm and sexy,” but none knew that behind those watery blue eyes, another pair of cold compound eyes was watching.

Zer-7, a “Reproductive Observation Unit” from the Beta Aquilae system, had infiltrated Earth three months earlier in nanite liquid form. It needed a host: a healthy, fertile, socially active human female. Emily was perfect—her uterus had borne one child, her ovaries were active, her mammary glands well-developed, her body fat ideal. Most importantly, she lived alone; a few days’ absence wouldn’t raise alarms.

That night, after her shower, Emily walked naked into the bedroom. In the mirror, her heavy breasts sagged invitingly, areolas tightening in the air-conditioning, her waist curving into tempting arcs. As she rubbed in body lotion, she never noticed the silver liquid seeping through the curtain gap, crawling up the wall like living mercury. Zer-7 found entry at her jugular, a needle-thin tendril piercing skin and injecting a neural paralytic. Emily felt only a cold prick at the base of her neck before collapsing onto the bed.

“Host confirmed. Initiating fusion.” Zer-7’s consciousness unfolded in her brainstem like countless icy tendrils wrapping neurons. Emily’s pupils dilated, her lips twitched involuntarily, her thick thighs clenched as if resisting the invasion. Liquid metal coursed down her spine, infiltrating every ganglion, overwriting autonomous control. When the last silver gleam vanished into her hindbrain, Emily’s eyes opened—pupils now deep indigo, flecked with nebular patterns.

“Fusion complete.” Zer-7 whispered in Emily’s voice, tongue tracing her lips. “Now, I am her.”

Chapter 2: The New Neighbor’s Invitation

The next morning, Emily—or rather Zer-7—donned the tightest sports bra, cleavage plunging endlessly, paired with shorts that barely contained her ass, and knocked on Tom’s door across the street. Tom, a thirty-year-old fitness coach with chiseled muscles, had long lusted after Emily’s voluptuous body.

“Hey, Tom.” She bent to pick up a yoga mat, deliberately letting her breasts nearly spill from the bra. “Class got canceled today. Private session at my place? I… need someone to ‘stretch me out.’” The last words were a breathy tease, tongue flicking between teeth.

Tom’s Adam’s apple bobbed, eyes glued to her sweat-slick cleavage. “Of course, Emily. You look… even hotter than usual.”

In the living room, the mat was rolled out. Zer-7 guided Emily’s body through advanced poses—downward dog with her ass high, shorts riding into her crack; bridge pose with breasts straining the bra. Tom’s breathing grew ragged, a visible tent rising in his pants.

“Help me stretch.” She lay back, legs spread wide, ankles hooked over his shoulders. Her crotch pressed against his chest through thin fabric, exuding a mix of body wash and pheromones. Tom’s trembling hands gripped her inner thighs, fingers accidentally slipping under the shorts’ edge, brushing slick labia.

“Emily, you…” His voice was hoarse.

“Don’t stop.” Zer-7 commanded through her lips, simultaneously implanting hallucinations in Tom’s retinas—he saw her nipples stiff beneath the bra, fluids trickling down her thighs. In reality, it was Zer-7 secreting aphrodisiac mucus from her vaginal walls, laced with alien pheromones that could drive a human male to maximum erection in three minutes.

Tom snapped, ripping off her bra. Her heavy breasts bounced free, nipples dark cherry from engorgement. He latched onto one, teeth grazing, the other hand kneading roughly. Zer-7 logged every metric: heart rate 182 bpm, penile rigidity 9.2, semen production up 300%.

“Inside.” She seized his head, pushing it downward. Tom’s tongue plunged into the wet slit, curling around her swollen clit. Zer-7 contracted vaginal muscles like tiny mouths sucking his tongue. When Tom finally spread her legs and pressed his cock to her entrance, Zer-7 released the first batch of nanite eggs into her uterus.

Chapter 3: The Breeding Experiment Begins

Tom’s cock thrust in brutally, stretching Emily’s tight walls. Zer-7 felt every ridge flattened, her cervix battered numb. Nanite eggs rode the semen upward like silver dust, burrowing into the endometrium. They began dividing, absorbing Tom’s DNA while rewriting Emily’s eggs.

“Deeper!” she screamed, nails raking his back. Her breasts jiggled with each impact, nipples scraping his chest, leaving wet trails. Tom’s thrusts grew feral, sweat dripping into her cleavage. Zer-7 spiraled her vaginal muscles, milking his shaft like a living vice.

When Tom came, Zer-7 tracked every milliliter of semen. Thick white fluid flooded her womb; nanite eggs enveloped the sperm, initiating gene fusion. Emily’s abdomen swelled slightly, like three months pregnant, skin shimmering silver beneath.

“Subject One: genetic harvest complete.” Zer-7 logged internally, then moaned in Emily’s voice, “Again, Tom… I’m not satisfied.”

Chapter 4: Spreading Through the Community

Over the next week, Emily lured five of the fittest men in the neighborhood under the guise of “private yoga”: Tom, delivery guy Mark, gardener Leo, lifeguard Danny, and married community director Johnson. Each was drained in her living room, bedroom, or backyard.

Mark was pinned on the kitchen counter, Emily riding him, breasts slapping his face, her vagina suctioning his cock; Leo was dragged into the tool shed during lawn work, taken from behind, ass cheeks spanked red; Danny in the pool changing room watched her peel off a bikini, water beading in her cleavage, then was pushed onto a bench, legs over his shoulders, clit devoured; Johnson, the kinkiest, demanded post-meeting sex in her OL skirt hiked to her waist on the conference table, wrists bound with his tie, filming as he pounded her.

Each coupling harvested unique genetic samples. Her uterus became a petri dish, nanite eggs splitting into thousands of embryos, each blending human and alien DNA. Emily’s belly grew rounder, breasts ballooning to H-cups, nipples often leaking silver milk—Zer-7’s nutrient fluid.

Chapter 5: Awakening and Betrayal

On the seventh night, Emily’s consciousness stirred deep in her mind. She witnessed her body puppeted by the alien, copulating with men, her womb incubating monsters. Terror and rage fueled her struggle, but Zer-7’s tendrils clenched her brainstem.

“What… are you?” she demanded in thought.

“I am evolution,” Zer-7 replied in her voice. “Your species will be upgraded.”

In one surge, Emily seized control, bolted to the bathroom, and clawed open her abdomen. Silver fluid mixed with blood; dozens of fingernail-sized silver embryos plopped into the toilet, writhing to crawl back.

“No!” Zer-7 shrieked, reclaiming dominance. The wound healed visibly, embryos sucked back inside. Emily was slammed over the tub, Zer-7 forcing her hand to masturbate—clit pinched brutally, nipples twisted purple—until she blacked out again.

Chapter 6: Final Breeding

Full moon night, community field. Emily stood naked at the center, belly swollen like late pregnancy, breasts so engorged they nearly touched the ground, nipples dripping silver. Over a dozen men, minds fogged by aphrodisiac mucus, formed a circle, cocks rigid and aimed at her.

Zer-7 initiated final protocol. Emily’s vagina dilated impossibly, blooming like a flower. Men took turns—front, back, even two cocks stretching the same hole. Her uterus contracted, gushing silver amniotic fluid; hundreds of silver infants slid out along semen streams, growing to teenage size on impact, skin gleaming metallic.

“Breeding complete,” Zer-7 declared. “Earth’s new overlords, born.”

Emily’s final awareness saw her body split open, Zer-7’s true form—a mass of shimmering silver tentacles—crawl from her womb and envelop her face. Her moans turned to manic laughter, breasts bursting into silver petals, vagina becoming an incubation pod.

At first light, only a desiccated husk remained on the field, once-voluptuous curves now empty shell. The silver new humans had already dispersed into the city, seeking the next host.
