Danica's fingers trembled slightly as she pressed the pen to the thick contract paper, the sterile hum of the facility's overhead lights casting a cool glow over the polished metal table where Marcus Hale stood watching with clinical detachment. The agreement spelled out every binding detail in crisp black ink: her body would be secured continuously for ten days in the glory hole chamber, limbs restrained by padded cuffs and straps that would hold her hips elevated and exposed, with mandatory silicone plugs inserted after each anonymous insemination to trap the seed deep within her womb, ensuring no leakage even as she drifted into fitful sleep under the constant cycle of use. The scent of antiseptic mingled with a faint musk from the adjacent rooms, and she felt a flush creep up her neck, her pulse quickening at the thought of what this would mean for her body—stretched, filled, and relentlessly claimed by strangers whose faces she'd never see.

Her longing for pregnancy had driven her here, an ache that had grown from quiet desperation into something visceral and all-consuming over the past year. At twenty-eight, Danica had imagined motherhood as a warm, blooming fullness, her belly rounding with life after tender nights with a partner, but repeated failures had left her empty and resolute, pushing her toward this extreme volunteer contract as the only path to the child she craved. The contract's rules amplified that hunger, transforming her quest into an endless, mechanical breeding that promised results through volume and retention, and as she signed her name with a final, deliberate stroke, a mix of fear and fierce anticipation coiled low in her abdomen.

Marcus led her without ceremony into the pre-stint examination room, where the air grew warmer and heavier with the tang of latex and lubricant. He instructed her to strip and recline on the padded table, her legs guided into stirrups that spread her thighs wide, exposing the delicate folds of her pussy to the bright examination light and his gloved hands. The speculum slid into her with a cool, unyielding pressure, stretching her vaginal walls as he adjusted it methodically, his fingers probing the slick entrance to her cervix while he noted her elevated temperature and the subtle swelling of her labia—clear signs her fertility window had opened wide. He inserted a thin ultrasound wand next, the device humming softly as it mapped her ovaries, confirming ripe follicles ready for release, then withdrew to palpate her breasts, thumbing her nipples until they stiffened under his detached touch, all while murmuring clinical observations about her body's optimal readiness for the unrelenting inseminations ahead.

Marcus continued his examination without pause, his gloved fingers returning to her exposed pussy to map its contours with precise, unhurried strokes. "Vaginal depth measures approximately seven inches at full extension," he noted aloud, his voice flat and professional as two fingers slid deeper inside her, parting the slick inner walls and pressing against the spongy tissue to gauge resistance and elasticity. "Cervix is positioned high and soft, with an os dilation consistent with peak ovulation—ideal for seed retention." He withdrew slightly to circle her clit with his thumb, observing the way it swelled under the indirect pressure, then inserted a calibrated probe alongside his fingers to record circumference at multiple points along her channel. "Labial swelling indicates heightened blood flow, and natural lubrication is copious—seventy percent above baseline. This will facilitate repeated penetrations without excessive friction damage."

Danica's breath hitched at the clinical recitation, her body betraying her with involuntary clenches around the intrusion even as shame and raw need warred in her chest. The longing that had brought her here flared hotter now, a deep, pulsing ache that made her hips twitch against the stirrups despite the restraints. She imagined the anonymous cocks that would soon fill this same space, flooding her with thick, hot seed meant only for one purpose, and the thought sent a fresh rush of wetness coating Marcus's fingers. He noted it immediately. "Subject exhibits strong arousal response to verbal detailing—pussy contracting rhythmically at six-second intervals. Will record for monitoring logs."

He removed the probe and replaced it with a wider speculum, cranking it open another notch to stretch her fully for visual inspection. "Cervical mucus is clear and stretchy, egg-white consistency—prime for sperm transport." The cool air of the room kissed her inner folds as he leaned in closer, dictating each observation with detached efficiency. Danica closed her eyes, surrendering to the exposure while her mind raced ahead to the ten days of unrelenting use that awaited, her body already primed and waiting to be claimed again and again.

Danica's body jolted as a sudden peak surged through her thighs, her pussy clenching hard around the open speculum while a rush of fresh slick coated Marcus's gloved fingers and dripped down toward her exposed anus. The orgasm hit without warning, hips bucking involuntarily in the stirrups as wave after wave rippled outward from her swollen clit, leaving her gasping and flushed. Marcus paused only to note the reaction into the overhead recorder, his tone unchanged. "Subject achieving spontaneous climax during cervical inspection—thighs trembling, vaginal walls pulsing at irregular intervals, copious lubrication increasing by an estimated thirty percent. Applying fertility fertilizer now to extend the ovulatory window by an additional forty-eight hours."

He reached for a small tube on the tray, squeezing a cool, viscous gel onto his fingertips before smoothing it directly over her parted labia and deeper along the stretched inner walls. The substance tingled as it absorbed, warming her already sensitive tissues and making the slickness inside her feel heavier, more insistent, as if every nerve ending had been coaxed into sharper awareness. "Fertilizer application complete—formula designed to thicken cervical mucus further and maintain follicular stability under repeated insemination stress," he continued dictating, two fingers now pushing the gel deeper, circling her cervix with methodical pressure. "Subject's arousal response persists post-orgasm; pussy remains engorged and receptive, with visible contractions drawing the gel inward. Breasts show persistent nipple erection, and heart rate elevated consistent with sustained excitement rather than distress."

Danica's breath came in shallow pants, the clinical words only heightening the raw need twisting low in her belly as the fertilizer's warmth spread, making her feel open and endlessly fertile. Marcus withdrew the speculum slowly, the metal sliding free with a wet sound, then pressed a fresh gloved palm over her entire mound to work the remaining gel into her skin. "Logging for program records: fertility window now optimized through day twelve if needed. Subject appears mentally aligned with the contract's demands, body exhibiting ideal conditions for continuous anonymous breeding and seed retention protocols." His detached efficiency left her trembling, the promise of the coming ten days pressing down like a physical weight even as her body hummed with reluctant, aching readiness.

Marcus guided her from the examination table with the same clinical efficiency, leading her down a short corridor into the glory hole chamber where the padded bench awaited, its surface cool and yielding beneath her skin as she climbed onto it. He worked methodically to secure her, wrapping padded cuffs around her wrists and ankles before drawing her arms forward and strapping them to the bench's frame, her hips elevated on a firm bolster that left her ass raised and her pussy fully exposed through the padded opening below. Additional straps crossed her lower back and thighs, locking her in place with her legs parted wide, the position forcing her swollen labia to part naturally and revealing the glistening entrance to her cunt, still slick from the examination and the fertilizer gel that kept her inner walls warm and receptive.

The first anonymous user arrived without introduction, the sound of a zipper and rustling fabric the only warning before a thick, veined cock pressed against her exposed folds. Danica gasped as it pushed inside without preamble, stretching her vaginal walls with a steady thrust that buried it to the hilt, the stranger's hips slapping against her restrained ass while his hands gripped the edges of the opening for leverage. Each stroke dragged over her sensitive tissues, her pussy clenching involuntarily around the intrusion as the warmth of the fertilizer amplified every sensation, her clit throbbing with the friction. He groaned low, pumping faster until his cock pulsed deep against her cervix, flooding her with hot, thick ropes of cum that coated her inner channel and pooled at her womb's entrance.

Marcus waited only until the man withdrew, then stepped forward with a thick silicone plug in hand, pressing its tapered tip against her cum-slicked pussy and working it inside with firm, twisting pressure until the flared base sealed her entrance completely. The plug trapped the seed deep, its slight vibration from her body's contractions keeping the warmth and fullness insistent as it stretched her just enough to prevent any leakage. Before the next user could arrive, he adjusted the final padded cuffs around her upper thighs and torso, ensuring no movement was possible even as the second cock—longer and thinner—slid into her plugged cunt after the plug's brief removal, thrusting with urgent need that made her restrained body jolt and her breath catch in a mix of overwhelmed dread and desperate, building arousal.

The second cock drove deeper with each relentless stroke, its slender length spearing through her fertilized slickness to nudge repeatedly against her cervix until the stranger grunted and unloaded in pulsing jets, adding another hot flood of seed that mingled with the first load trapped inside her. Marcus withdrew the plug only long enough for the man to finish, then immediately resealed her with a fresh one, twisting the wide silicone base flush against her swollen labia to lock everything in. The third encounter followed swiftly, a shorter but thicker cock forcing its way past the plug's removal and pounding her with short, brutal thrusts that made her restrained thighs quiver and her breath hitch into broken moans, the anonymous user's balls slapping wetly against her exposed clit until he emptied himself with a groan, his cum joining the growing pool deep in her channel.

Marcus's gloved hands returned at once, pressing the tapered plug back inside her with deliberate pressure, its bulbous head stretching her pussy lips wide before settling into place with a soft pop that sealed her completely. The fourth user wasted no time, shoving a curved cock that hooked upward to grind directly over her g-spot with every withdrawal, drawing involuntary spasms from her inner walls as he rutted until he came in thick spurts that oozed around the temporary gap before the plug reclaimed her. By the fifth encounter, her body had begun to ache with the constant stretch and fullness, yet her hips twitched helplessly against the straps as another anonymous shaft—veined and insistent—plunged in after the plug's removal, fucking her with slow, grinding rolls that pressed her clit against the padded bench edge until the man finished with a series of shallow jerks, flooding her once more.

Marcus stepped forward to reinsert the plug, his clinical voice activating the overhead recorder as he worked it home with firm twists, ensuring the flared base sat snug against her dripping folds. "Subject's pussy shows progressive distension after five inseminations, with visible labial puffiness and continuous contractions around the plug base that draw seed deeper toward the cervix. The silicone device maintains full retention with zero leakage observed, its internal ridges stimulating mild peristaltic response that massages the pooled ejaculate against the os while the slight taper prevents expulsion even under sleep-induced movement. This design proves highly effective for prolonged seed retention, keeping the fertilized mucus in optimal contact with the cervical opening and amplifying the subject's internal warmth and pressure sensations, which correlate with sustained arousal and elevated heart rate throughout the cycle."

Marcus finished dictating and stepped back, but the next anonymous user was already positioning himself, his heavy cock nudging the plug aside before driving in with a single forceful thrust that buried every veined inch deep in Danica's cum-slicked channel. This one was broader than the others, stretching her inner walls to their limit as he rutted with grinding rolls of his hips, the head battering her cervix while her restrained body jolted helplessly against the straps, her swollen breasts pressed flat to the bench and nipples scraping the padding with each impact. He fucked her relentlessly, sweat-slick balls slapping wetly against her exposed clit until he groaned and pumped thick, pulsing jets of seed that joined the others, the overflow trickling around his shaft before he withdrew and left her gaping briefly.

Marcus waited only for the withdrawal before sliding the plug home again, but paused as his gloved fingers traced the glistening mess coating the bench beneath her spread thighs. "Subject's own arousal has increased markedly," he noted into the recorder, voice still detached as he observed the fresh slick dripping steadily from her plugged pussy to pool on the floor. "Natural lubrication now exceeds previous measurements, mixing with ejaculate and creating significant runoff—recommend scheduling the cleaning crew for more frequent mopping of the chamber floor to maintain hygiene standards during the remaining contract days."

Danica's breath shuddered out in a broken moan, her body trembling with the relentless fullness trapped inside her, the emotional weight of her choice pressing down even as the constant stimulation kept her hips twitching involuntarily against the restraints, a mix of desperate hope and overwhelming sensation flooding her senses while the next cock pressed forward to claim her once more.

The next cock pressed forward without hesitation, thick and ridged along its length as it slid into her cum-slicked depths, displacing the pooled seed with each inch it claimed. Danica's body jolted against the straps as the stranger's hips slammed into her raised ass, his thrusts deep and purposeful, grinding the head against her cervix while his hands gripped the padded edges for leverage. Her inner walls clenched around him involuntarily, the fertilizer gel amplifying the wet heat and friction until he grunted and released in heavy pulses, adding yet another load that mingled and swelled the fullness trapped within her. Marcus was there immediately upon withdrawal, pressing a fresh plug into place with firm, twisting pressure that stretched her swollen pussy lips wide before seating it flush, trapping everything deep as her exhausted muscles fluttered around the intrusion.

Her breath came in ragged gasps, exhaustion weighing on her limbs like lead even as her clit throbbed persistently against the
