Melaria's mind drifted inward amid the clinical hum of equipment, her thoughts a tangle of desperate longing and the overwhelming physical reality of her stretched, cum-laden body—the way the trapped seed sloshed warmly with every shift, pressing insistently against her deepest recesses as if seeking to claim her from within. The third partner's thick, blunt cock withdrew with a wet suction, leaving her pussy clenching around the resealed plug, but the sensation lingered like an echo of penetration that promised more, stirring a profound mix of vulnerability and fierce determination within her. She craved the child that might finally anchor her life, each sealed load a step toward that fulfillment, even as her walls throbbed with the burn of repeated stretching and the subtle ache of overfullness swelling her lower abdomen.

The harness adjusted with a soft mechanical whine, tilting her higher still as a fourth breeder stepped between her suspended thighs—this one taller, with a cock longer and tapered to a precise point that Nurse Lena guided through the adapter with efficient care. Dr. Voss's voice remained steady, directing the rotation to maximize volume, and the new thrusts came in powerful, measured strokes that escalated the intensity, each one driving deeper to nudge directly against her cervix in deliberate attempts at penetration. Melaria gasped at the intimate contact, the pointed head prodding the tight barrier with wet, insistent pressure that sent sparks through her nerves, her pussy fluttering and slicking further around the invasion as fresh, heavy spurts of cum joined the reservoir, swelling the sealed mixture until her belly visibly rounded under the lights. The collar registered her heightened pulse and contractions, logging the way her body responded to the escalating rotations—three, then four, then five partners in succession, each adding thicker loads that churned and pressed with greater cumulative force.

As the fifth withdrawal triggered another reseal, the plug expanding to lock everything deeper, Melaria felt the emotional weight settle alongside the physical: her resolve hardening even through the raw sensitivity of her overstimulated cunt, the constant monitoring, and the promise of overnight suspension to let the volumes settle against her cervix in hopes of true contact and implantation.

Melaria's resolve hardened even through the raw sensitivity of her overstimulated cunt, the constant monitoring, and the promise of overnight suspension to let the volumes settle against her cervix in hopes of true contact and implantation. The harness whirred softly as it locked her higher, thighs spread wide and pelvis elevated so the sealed plug pressed the churning mixture of cum firmly against her deepest walls, the warmth radiating through her lower belly in heavy, insistent pulses that made her breath hitch with every subtle shift. Her internal reflections turned inward to the sensations flooding her—the slick, overfull stretch of her pussy around the expanding plug, the way each prior load sloshed and pooled with viscous heat, coating her cervix in layers of thick seed that sought entry with every contraction the collar recorded. Emotional depth anchored her, the desperate ache for a child transforming the vulnerability of suspension into fierce purpose, even as her walls throbbed from the repeated invasions.

Dr. Voss directed the final adjustments, his clinical gaze on the monitors while Nurse Lena checked the restraints, the overnight protocol engaging with a steady hum that held Melaria suspended for optimal settling. The plug's adapter allowed no escape, trapping the escalating volumes as her body responded with involuntary clenches, the trapped semen pressing insistently at her cervix in wet, seeking nudges that echoed the earlier attempts. Reflections on the rotations surfaced amid the haze: the third partner's blunt thickness had stretched her widest for initial accommodation, the fourth's tapered length had driven the most direct prods against her tight barrier with measured force, each thrust building pressure until fresh spurts added to the reservoir, swelling her visibly as contractions peaked. Five partners in total had rotated through, volumes compounding into a heavy, sealed load that the sensors logged for depth and retention, her pussy clenching around the plug's firm presence while gravity and positioning worked to force true cervical penetration overnight.

By morning, the monitors chimed with data as Dr. Voss reviewed the readings aloud in his detached tone, noting the fourth partner's longer, tapered cock had achieved the highest cervical contact metrics at seventy-two percent penetration attempts with peak contraction responses registering at 4.8 on the fertility scale, outperforming the third's girth-focused volume at forty-eight percent and the fifth's broader but shallower deposits at thirty-five percent. Alpha's initial load and the second's curved precision followed closely in readings, contributing to a combined prognosis of sixty-five percent implantation likelihood after this cycle, with recommendations for intensified cervix dilation in subsequent days if no conception registered, the sealed overnight hold deemed effective for maximizing the trapped semen’s proximity to her depths amid her body's resilient responses.

As the monitors quieted, Dr. Voss turned his full attention to Melaria's suspended form, his voice clinical yet precise as he addressed her directly. "Day three begins with escalated protocol due to persistent non-implantation—your cervical os remains resistant, allowing only partial seepage of the prior loads despite the overnight seal. We will proceed with manual dilation attempts alongside inseminations to force deeper penetration, rotating partners to maximize volume and pressure against your uterus until conception registers or we advance to free-use protocols." He instructed the incoming breeders, "Target the cervix directly with each thrust; apply steady pressure to breach the barrier, depositing semen as close to the os as possible before withdrawal."

Melaria's breath caught at the words, her internal reflections surfacing through the haze of vulnerability—the way her overfull pussy throbbed around the plug, the emotional weight of her body's refusal to yield clashing with the fierce ache for the child that might finally complete her. The harness lowered her slightly for access as the first breeder of the day, a powerfully built man with a ridged cock, positioned beneath her spread thighs. He pushed through the adapter with deliberate force, his thick shaft stretching her slick walls anew as he drove upward, the blunt head prodding insistently at her cervix in repeated nudges that made her gasp and clench. Each thrust built deeper contact, his grunts mingling with the wet squelch of displaced cum, until he buried himself and released in heavy pulses, the hot jets flooding past the partial barrier to swell her womb further.

Nurse Lena adjusted the plug's seal amid the rotations, her empathetic touch contrasting the mounting intensity as a second then third partner took their turns, their cocks varying in length and girth to escalate the attempts— one tapered sharply to jab at the cervical entrance with rhythmic precision, forcing micro-dilations that sent sparks of raw sensation through Melaria's core, while the next delivered thicker volumes that churned the reservoir into a pressurized heat against her depths. Her belly rounded visibly with the compounded loads, contractions rippling under the collar's watch as reflections on the sensations flooded her: the burn of repeated stretching, the slick overflow trapped inside, the deepening resolve that each failed cycle only hardened her will to endure. By the fifth rotation, the breeders followed Dr. Voss's directives explicitly, holding deep for sustained cervical pressure during releases that coated her interior in fresh waves, her body trembling in the harness amid the promise of even more unrelenting sessions ahead.

Melaria's body trembled in the harness amid the promise of even more unrelenting sessions ahead, her mind reeling through layered reflections on the sensations that had built to this point—the raw burn of repeated cervical nudges sending jolts of overstimulation through her core, the viscous churn of compounded seed pressing outward against her swollen walls with every involuntary clench. Dr. Voss's voice droned on with clinical detachment as he dictated the day's medical report into the recorder, noting escalating metrics from the five rotations: cumulative semen volume at 42 milliliters trapped against the os, cervical contact attempts reaching 68 percent success with the tapered and ridged partners achieving partial dilation of 0.8 centimeters, her contractions peaking at 5.2 on the fertility index during sustained pressure holds, and visible abdominal distension measuring 4.7 centimeters increase due to the pressurized reservoir. Nurse Lena monitored the collar's logs, murmuring observations on Melaria's resilient pulse patterns while prepping the overnight protocol, her empathy a steady counterpoint to the mounting physical demands.

The harness whirred into its final elevated lock, suspending Melaria's spread form with her pelvis tilted sharply upward so gravity could aid the sealed mixture's migration toward her depths. A long, deliberate description of the overnight cum sealing unfolded as Lena replaced the adapter with a thicker, ribbed bio-polymer plug that expanded in stages, its flared base nestling flush between her slick, puffy folds while internal ridges locked against her inner walls to prevent any seepage; the device pulsed faintly with embedded sensors that would track retention overnight, forcing the thick, creamy loads—now a churning blend of multiple donors' ejaculate—to slosh and pool directly at the cervical barrier in warm, insistent waves. Each subtle shift in the suspension sent fresh sensations rippling through her: the viscous seed coating her os in heavy layers, the plug's unyielding girth stretching her entrance with a constant, throbbing fullness that mingled ache and arousal, her lower belly rounded and taut under the lights as the trapped heat radiated outward, her pussy clenching reflexively around the intrusion in futile attempts to draw more inside.

Melaria's resolve anchored her through the vulnerability, the emotional hunger for conception transforming the sealed pressure into a profound intimacy with her own body's limits, even as the collar hummed its ceaseless tracking of the overnight settling that promised deeper implantation by morning.
