LEWDS - NIKKE WG - Elegg’s upgrades - 01

The lab lights hummed low and clinical, casting a sterile glow over the padded examination platform where Elegg sat. Her usual bright energy had been dialed down to something tighter, more focused. The purple dildo rested heavy in her palm—thick, slightly curved, its surface laced with soft glowing circuits that pulsed in time with the holographic countdown floating above the console.

Program Installation: 47

She had already stripped out of her combat suit. The fabric lay discarded in a neat pile. Her body was still lean and compact, the familiar athletic lines of a Nikke who spent more time troubleshooting code than trading blows. Small, firm breasts, a flat stomach with just the faintest suggestion of softness, narrow hips. That was about to change.

Elegg spread her knees wider on the platform, the cool air kissing the slick folds between her legs. She was already wet. The device required arousal to sync properly; the technicians had been very clear about that. She pressed the flared head against her entrance and pushed.

The stretch was immediate and deep. The dildo sank into her with a wet, deliberate glide, the circuits along its shaft lighting up the moment her inner walls closed around them. A soft chime sounded. The countdown ticked down.

She began to thrust.

Each slow drag outward and heavy push inward sent a ripple of pleasure through her core. The device was designed to read every clench, every flutter of her pussy, and translate it into code. But the side effect—the part she had been warned about only in the vaguest terms—started almost at once.

Her lower belly gave a soft, liquid pulse. A thin layer of softness bloomed under the skin, rounding the plane of her stomach just enough that the next thrust made it jiggle faintly. She gasped, hips rolling to meet the next stroke. The sensation of the thick shaft spreading her open mixed with the strange, warm pressure of new fat settling into place.

Another thrust. Her thighs thickened by a visible fraction. The outer curves pressed against the edges of the platform’s padding. When she squeezed her legs together around the dildo, the soft flesh of her inner thighs kissed and parted with a quiet, wet sound. Her clit throbbed against the ridge near the base every time she bottomed out.

Elegg’s free hand drifted up to cup one breast. It had already grown. The modest handful now spilled more fully over her fingers, the nipple tighter, more sensitive. She pinched it while she fucked herself deeper, and a soft, involuntary moan slipped out.

44… 43… 42

The changes accelerated with every stroke. Her belly rounded further, rising into a soft, pale dome that trembled when the dildo slammed home. The skin stretched smooth and warm. She could feel the weight of it now—small but undeniable—pulling gently downward each time she lifted her hips. Fat padded her hips and the upper slopes of her ass, turning the once-tight curves into something plush and yielding. When she reached back to brace herself, her fingers sank into the new softness of her own backside.

She was panting. The countdown glowed steadily lower.

Her breasts were heavier now, each one a full, soft weight that bounced with every thrust. The undersides rested against the upper curve of her belly whenever she leaned forward. She cupped them both, thumbs circling the stiff nipples, and the dual sensation of her own hands and the relentless stretch in her pussy made her clit pulse hard.

“Fuck…” The word left her in a shaky breath. The device rewarded the vocalization with a deeper internal vibration. Her walls fluttered around the purple shaft. Another soft surge of fat rolled through her midsection, thickening her waist, softening the definition of her ribs. She was starting to look… rounder. Softer. The athletic lines were blurring under a smooth, even layer of new flesh.

Elegg’s thighs had grown wide enough that they pressed together even when she tried to keep her knees open. The soft inner flesh rubbed and stuck slightly with each movement, shiny with the slick that kept dripping down onto the platform. Her pussy felt hotter, swollen, greedily clinging to the dildo on every withdrawal as if it didn’t want to let the device leave. She drove it back in harder, chasing the bright spike of pleasure that came with being filled so completely.

Her belly jiggled more noticeably now. It had risen into a proper soft pouch, the kind that would rest against the tops of her thighs if she sat down fully. When she looked down, she could no longer see the base of the dildo without the curve of her stomach interrupting the view. The sight made her clench hard. Another tick of the countdown. Another slow bloom of weight across her hips and the lower swell of her ass.

She was breathing harder, cheeks flushed, eyes half-lidded. The sexual heat and the transformation fed each other. Every time the thick purple shaft stretched her open, her body answered by packing on more softness. Her breasts had grown heavy enough that they needed both hands to support them properly; the soft undersides were warm against her palms, the nipples dark and tight. She rolled them between her fingers while she fucked herself, and the dual pleasure made her thighs shake.

Fat had settled into her upper arms in a soft, feminine layer. When she braced one hand against the platform, the flesh of her upper arm trembled. Her once-narrow waist had thickened into a gentle, continuous curve from ribs to hips. She was no longer lean. She was… soft. Rounded. The early stage of chubby.

The dildo’s circuits glowed brighter. The program was taking hold faster. Elegg’s belly rose higher with each thrust, the soft dome now large enough that it bounced and settled with a quiet, heavy motion every time she drove the shaft deep. She could feel the weight of it in her posture—the slight forward pull, the way her center of gravity had already begun to shift. Her hips had widened further; the soft outer curves of her thighs and ass spilled over the edges of the platform padding. When she clenched around the dildo, the new thickness of her thighs pressed firmly together, trapping heat and wetness between them.

She was moaning openly now, low and continuous. The stretch of her pussy around the thick purple length, the wet sounds of every thrust, the growing heaviness of her own body—all of it coiled tight in her core. Her clit was swollen and sensitive; every time the base of the dildo ground against it, a sharp pulse of pleasure raced up her spine.

Her breasts rested fully on the upper slope of her belly now, soft and heavy, the nipples brushing the warm skin with every movement. She cupped them again, squeezing, feeling the give of the new fat. The sensation made her hips roll harder. Another surge of softness rolled through her midsection and lower body. Her belly rounded further, the soft lower curve beginning to rest against the tops of her thickening thighs whenever she sank down fully onto the dildo.

She was chubby. Properly, visibly chubby. Soft arms, soft thighs that pressed together, a soft belly that jiggled with every thrust, breasts that had grown into full, heavy handfuls. The athletic silhouette was gone, replaced by a warm, rounded, plush version of herself that felt almost too sensitive to touch.

Elegg’s free hand slid down over the curve of her stomach, fingers sinking into the soft, warm flesh. She could feel it tremble under her palm with every impact of the dildo. The countdown glowed steadily lower. Her pussy clenched rhythmically around the thick shaft, greedy and slick, the wet sounds louder now that her thighs were so much thicker and closer together.

She was close—to orgasm, to the end of the countdown, to whatever the finished program would do once it fully installed. The next thrust made her belly bounce heavily. The one after that made her breasts sway and settle against it. She was breathing in short, shaky gasps, eyes locked on the glowing numbers.

She drove the dildo in deep and held it there, grinding, feeling the thick length press against every sensitive place inside her while the soft weight of her new body shifted and settled around it. Her thighs quivered. Her belly rose and fell with each rapid breath. The soft undersides of her breasts were warm and heavy against the upper curve of her stomach.

One more hard thrust. The wet sound of it filled the quiet lab. Her chubby body jiggled—belly, breasts, the soft outer curves of her thighs and ass all moving together in a single heavy wave. Pleasure spiked hard and bright. The circuits along the purple shaft flared brilliant white.

Elegg’s eyes widened. The countdown hovered, the final number glowing steadily, the program’s last fraction of a second stretching out like a held breath. Her soft, rounded body trembled around the thick dildo still buried deep inside her. The soft weight of her belly pressed warm against her thighs. Her heavy breasts rose and fell with every shaky inhale.

The number had not yet reached zero.

And something inside the device was still changing.
