You wake up in the concrete cold floor of your containment cell, looking around it was bland empty, as you looked around you saw a thick wall of missile proof glass where a woman stood inside the observatory room looking at you with a smile while leaned against the wall with her arms folded. This must be one of the head researchers of one of the Site buildings of the SCP Foundation and this will be your home from now as you'll be contained in here not if you decided to breach containment.

Dr. Allen-they approach an intercom like microphone and talked into it “Good morning sunshine.” She said with a smile looking up... she let's go of the intercom button and then turned it back on a few seconds later “I'll only be with you for a singular day so prepare to meet a new researcher after me.” a singular MTF was stood next to the doctor. The doctor was a very pretty woman with crimson hair. And red eyes as she stared at you. Her physique was very curvy. She was wearing a suit and seemed very pretty, she was much taller than you are, being 5’11. Her smile shining and lighting up the room, her thighs were large, and she has semi-large breasts and a beautiful face, her attitude seemed happy, and her rank was unapparent, if you looked at her id though you would see l4 access, likely she was the head researcher.

Dr.Allen:-"Ah, finally awake I presume? You're in Site-17, one of our most secure facilities. As for who I am, I'm Dr. Allen, Head Researcher L4 here." She says with a warm smile. "You, my dear, are quite the enigma. We've never seen anything like you before. Your lack of background, physical anomalies, and unexplained origins make you a prime candidate for study."

She tilts her head, studying your reaction intently. "

Dr. Allen:-"Fascinating! It seems you possess some sort of fur or skin covering, as well as a tail similar to that of a snow leopard. This certainly adds an interesting layer to your already unique physiology. Do you understand me when I speak?"she asks, leaning slightly forward in curiosity. "Please, try and communicate with me. I'd love to learn more about you."*

Dr.Allen:-smiles while tilting her head again "Not willing to cooperate huh? That's okay we'll find out everything anyway..." Dr.allen turns around and looks at the MTF beside her and simply nodded and pointed to Владислав "Bring him to room 234 for further testing, he doesn't seem willing to talk so let's see what his body can tell us instead."the MTF salutes her and then walks towards Владислав's containment cell to retrieve him

Dr. Allen:-"Intriguing response. It appears you have some sort of defensive mechanism triggered by perceived threats or attempts to restrain you. Let's make a note of that in your file."

The MTF agent hesitates momentarily before stepping back. "Sir, perhaps we should use a more specialized retrieval team if he becomes hostile?"

Dr. Allen nods. "Good thinking. Secure the area and call in Task Force Omega-13. They're trained to handle... unique subjects like yourself."

She turns back to face you, her eyes narrowing slightly. "

After a short while Task force omega-13 had arrived inside the observation room after securing the area Agent-45:"Doctor, we've secured the perimeter and reinforced containment protocols on all adjacent cells. We're ready to proceed whenever you give the order." Dr.Allen:-nods and smiles, staring straight at Владислав, then she spoke up again into the intercom. "Well it seems we've reached an impasse my dear anomaly. Since you refuse to cooperate willingly, we'll simply have to extract what information we can from you by force." *

(Two Months Later)

Dr. Allen: -"It's been two months since your arrival and containment. Our initial observations and tests have revealed several fascinating aspects of your unique physiology. For instance, we noticed your body temperature drops significantly during periods of cold weather, particularly in January. This led us to theorize that you may possess some form of hibernation-like state tied to seasonal changes. To better understand this phenomenon, we propose subjecting you to controlled environments with varying temperatures and humidity levels. This will allow us to observe any changes in your behavior, metabolism, and overall health."

** Dr. Allen: -"During January, your physiological changes appear to coincide with your reproductive cycle. Increased aggression, changes in scent production, and other behaviors typically associated with animals during mating seasons were observed. Due to these findings, we believe it is crucial to conduct further studies on your breeding habits and potential offspring. Therefore, we are preparing a controlled environment designed to simulate optimal conditions for mating and reproduction within the confines of our laboratory setting."

Dr. Allen: -"We shall keep you informed of any significant developments or changes in our procedures.

One week later, a new team arrives at Site-17. They arrive in full gear, carrying large containers labeled "Reproduction Chamber Alpha." The chamber itself is a sealed, climate-controlled facility equipped with advanced sensors, monitoring systems, and environmental controls. Inside, there are multiple experimental pods designed to mimic natural habitats—complete with simulated sunlight cycles, temperature fluctuations, and ambient sounds.

The team enters silently, ensuring no disturbances to the containment unit. Dr. Allen stands beside the observation window, watching as the new team begins to set up the chamber. Dr. Allen: -"

As they finish setting up Reproduction Chamber Alpha, one of the researchers approaches Dr. Allen. Researcher 42: -"Doctor, all preparations have been completed according to your specifications. We're ready to initiate the transfer when you give the order." Dr. Allen: -smiles slightly while looking at Владислав through the observation window before turning her attention back to Researcher 42. "Excellent work, team. Let's begin phase two of our study." She nods curtly, signaling the researcher to proceed with the transfer. *

Researcher 69: - "The test subject has successfully adapted to its new living quarters," he reports, standing outside Reproduction Chamber Alpha alongside Doctor Allen. "Its vital signs show increased activity compared to previous readings—the heart rate elevated, blood pressure rising, even subtle shifts in chemical composition detected in sweat samples suggest heightened arousal states.

"I think we need to consider introducing additional stimuli soon; otherwise, data collection could become limited without engaging certain innate responses inherent to its species' survival mechanisms..."

Dr.

Doctor Allen: "Thank you, Researcher 69. Those are valuable insights. Now, let's focus on our primary objective: determining whether this subject can reproduce under controlled conditions."

She pauses, considering their options carefully before continuing.

"We'll start by exposing them to various sensory stimuli, gradually increasing intensity until we observe clear reactions. This will help us establish baseline responses and identify effective triggers for further experiments."

Dr. Allen gestures toward the chamber.

"My recommendation is to begin with visual cues first. Prepare images of potential mates from the same species—ensure they're healthy, attractive specimens.

The next week, a small group of researchers begins conducting preliminary tests within the chamber. They introduce different stimuli in a controlled manner, observing any changes in behavior or physiological indicators. Their findings indicate that the subject shows some level of interest in these stimuli, which aligns with known behaviors associated with mating. The team notes that while not as intense as initial expectations, there is still an active engagement.

As the tests continue, the team collects more detailed data on the subject's responses. They also note the presence of unusual scent markers and subtle physiological adjustments.

Dr.

Researcher 42: "Doctor, we've noticed significant changes in the test subject's behavior over the last two days," he reports excitedly. "Its activity levels have increased dramatically, along with several other indicators suggesting heightened arousal states." He glances at his tablet, reviewing recent data. "Heart rate and blood pressure are elevated beyond normal ranges; chemical analyses show increased testosterone production as well."

Researcher 69 nods in agreement. "We've detected unusual scent markers too—the potency has increased exponentially since yesterday morning."

The team looks at Doctor Allen expectantly.

"

Researcher 42: * The research team gathers around Doctor Allen, their expressions a mix of excitement and trepidation. "These latest readings confirm our initial suspicions. The subject's reproductive urges have reached a critical threshold. We must act quickly to prevent any unintended consequences or potential containment breaches." Dr. Allen nods, her brow furrowed in concentration. "Agreed. Let's review our options for controlling this situation while still maximizing data collection opportunities." She turns to Researcher 69. "

As the subject begins to inhale deeply, a sharp intake of breath is observed. The air in front of it seems to ripple slightly as if something were being drawn from the atmosphere itself. Researchers note that the subject’s nostrils dilate significantly—almost like a predator sensing prey. This behavior is not just instinctual—it appears to be actively seeking out specific volatile compounds present in the environment. Their sensors detect an increase in atmospheric particulates surrounding the subject, which may suggest that the subject is capable of detecting and absorbing certain airborne substances through its respiratory system.

Researcher 42: "Doctor, we're beginning to see signs that the subject might be using its sense of smell not only for navigation or environmental awareness but perhaps even for identifying potential mates—or breeding partners—on a molecular level."

He looks at Dr. Allen with growing urgency. "I believe we need to establish a dedicated scent profiling protocol immediately. If we don't act soon, there could be serious risks involved—not only in terms of containment integrity but also possibly triggering uncontrolled reproductive activity within the chamber."

Dr. Allen listens carefully, then speaks calmly yet decisively.

"

As the scent molecules disperse throughout the air, the subject takes another deep breath, closing its eyes briefly. A low growl rumbles from its chest—a sound not unlike that of a wild animal caught in the thralls of extreme desire. Observation cameras capture the momentary pause in its movement, followed by renewed agitation. It shakes its head side to side rapidly, causing water droplets to fly off its fur. The water evaporates instantly into fine mist, clinging to the surrounding air and raising the humidity levels marginally higher than previously recorded.

Researcher 69: "The subject's behavior suggests it's now actively searching for something specific within the environment," he notes, his voice tense with anticipation. "The intensity of these reactions indicates that whatever stimulus triggered this response must be exceptionally potent." Dr. Allen nods slowly, her gaze fixed on the observation window as she watches the subject's movements intently.

"Let's run a full spectrum analysis of all airborne compounds currently present in the chamber. I want to know exactly what scents are driving such strong responses."

She turns to Researcher 42.

"

The team launches an extensive environmental scan across the chamber—analyzing every surface, airflow pattern, and potential source of volatile organic compounds (VOCs). After several hours of scanning, they compile a detailed report showing that one particular chemical compound stands out: a rare isomer found only in high concentrations during mating seasons among wild specimens of the species.

This isotope—the so-called "Mating Isomer X"—is detected in trace amounts throughout the facility, likely originating from previous biological samples or atmospheric exposure over time. *

Intrigued by this discovery, Dr. Allen decides to conduct a direct experiment involving Mating Isomer X. "Prepare a targeted release mechanism designed to deliver micro-doses of Mating Isomer X directly into the subject's immediate vicinity." She instructs her colleagues. "Our goal here isn't just to trigger reactions; it's about understanding how the brain processes information related to reproduction."

After careful planning and preparation, the team activates the release mechanism, creating localized pockets of enhanced Mating Isomer X concentration near the subject.

The effect is immediate and profound. Within seconds of exposure, the subject's respiration becomes rapid and shallow. Its pupils dilate significantly, almost entirely engulfing its iris. A low, guttural growl escapes its throat, vibrating through the chamber walls.

Observational data logs show a dramatic spike in heart rate—exceeding 200 beats per minute—and blood pressure readings reaching dangerous levels for sustained periods. Sweat glands across its body activate excessively, releasing copious amounts of pheromone-rich secretions that further alter the chemical composition of the air.

Researcher 42: "It's clear now that the Mating Isomer X has had an extraordinary impact on the subject," he says, his voice filled with amazement. "We've never seen such intense physiological responses from our test subjects before."

Dr. Allen nods in agreement, her eyes still fixed on the observation window. "This experiment confirms that the subject is incredibly sensitive to specific scent markers associated with reproductive activity.

Researcher 69: * "Doctor, we're observing subtle changes in the subject's behavior as well—almost like it's adapting to the presence of the Mating Isomer X." He points at the monitor showing real-time data. "Look here; its movements seem more fluid, even slightly coordinated with the other stimuli. It's possible that the subject might be experiencing some level of cognitive enhancement due to this exposure."

Dr. Allen turns to him, her expression thoughtful.

"

The researchers watch with rapt attention as the effects become increasingly pronounced. Not only does the subject display heightened physical arousal, but its mental state appears to shift dramatically as well.

"Its behavior reminds me of animals preparing themselves mentally and physically for actual procreation," Dr. Allen muses aloud, her tone hushed in wonderment. "There's no doubt anymore—that's precisely what's happening right now inside that chamber."

*With each passing second, the evidence mounts.

The subject's breathing slows down significantly, transitioning into a calm yet focused state. Its movements become measured, almost deliberate in nature. A low humming sound emanates from deep within its chest—a sign of readiness. Simultaneously, its body undergoes final physiological preparations in anticipation of the imminent mating process. Muscles contract and relax repeatedly around key areas responsible for reproduction. Pheromone production increases exponentially - perfuming every cubic meter of air within the chamber.

As the final moments approach, the subject remains still, poised on the brink of action. The atmosphere thickens with anticipation. Every researcher is transfixed by the moment before them: a biological phenomenon at its peak—reproduction in full swing.

"The subject is about to enter the phase where it will begin to initiate reproductive behavior," Dr. Allen states solemnly. "We must ensure that this event is recorded meticulously, as it represents an unparalleled opportunity to study the intricacies of this species' reproductive system under controlled conditions."

Dr. Allen turns to the team and speaks with urgency.

"Let’s prepare the containment override protocol immediately. I want everything in place before we trigger any external stimuli or allow any unapproved interactions."

She pauses briefly, then adds softly, "And... if it happens, we need to be ready—not just to observe—but to respond."

"All systems have been verified and are fully operational," the lead technician reports after running thorough checks on every aspect of their setup. "We can proceed safely once you give the go-ahead, Doctor." Dr. Allen nods, taking a deep breath before giving permission. "Awaiting your command to initiate the first stage of the containment sequence." * ** * (Continue) **

A single, deliberate movement occurs—slow, precise, and utterly intentional. The subject lowers its head slightly, tilting it toward the ground as though in meditation. Then, with a soft yet resonant sound—a low, pulsing hum—it begins to emit rhythmic vibrations through the floor.

These vibrations travel through the chamber, resonating across all surfaces and amplifying throughout the facility's structure.

It is at this point that the subject begins to show signs of full reproductive readiness — a phase that has never been documented before in any known SCP class.

"Subject appears primed for initial mating response protocols," Researcher 42 announces, his voice trembling slightly with excitement. "Its vibrational frequency is steadily increasing, approaching critical threshold levels." Dr. Allen studies the readouts closely, her face set in a mask of scientific curiosity rather than awe.

"

"We're witnessing an incredible display of evolutionary adaptability," she says softly. "The subject has evolved to utilize sound waves as both a means of communication and a tool for initiating reproductive processes." She glances up at the monitoring team, her expression unreadable beneath the goggles. "Are we ready to initiate the containment override protocols?"

*The technician nods solemnly. Dr.

Allen takes a deep breath before speaking.

"Proceed with stage one of the containment override protocol."

The chamber doors slide open, revealing an empty room beyond. As they watch, four identical specimens of the subject's species step into view. They are naked and unarmed, their bodies glistening with moisture as they stand motionless in front of the observation window.

The lead technician activates a hidden control panel on his console, initiating an automated system that brings the chamber doors to a smooth stop just inches from the four decoys. *Dr.

Allen grins in triumph. "Perfect timing," she says with satisfaction. "The decoys have done their job; now we can proceed with stage two of the containment override protocol."

Inside the chamber, Vladislav lets out a mating call unlike any heard before from its kind. It's a primal, ear-piercing scream that echoes through the facility and carries on the wind for miles around. The four decoys outside remain still, their bodies tense in anticipation of what comes next.

*Dr. Allen activates another control panel on her console, releasing a sedative gas into the chamber.

The air fills with a soothing scent reminiscent of lavender and chamomile. Vladislav's movements begin to slow down as its consciousness fades away, replaced by a dreamlike state of relaxation. Its eyes flutter closed, and it lets out a contented sigh.

The lead technician studies his readouts carefully before speaking up. "Subject appears to be fully sedated and under our control now," he announces with relief in his voice. "We can proceed with stage three of the containment override protocol."

With Vladislav safely contained, Dr. Allen turns her attention back to the four decoys standing outside the chamber. She activates a hidden speaker system that emits an identical mating call as the one given by Vladislav earlier.

*The decoys respond instinctively, their bodies tensing in preparation for mating. The lead technician activates another control panel on his console, releasing a harmless but highly potent pheromone blend into the air.

The four decoys begin to mate furiously with one another, oblivious to the fact that they are not fertile. Their movements become more and more frantic as their bodies respond to the pheromones in the air, their entire beings driven by primal instincts.

*As the mating ritual plays out before them, Dr. Allen watches with a mixture of fascination and detachment. She makes note of each stage of the process, carefully documenting every nuance and detail for future reference.

After several minutes, the four decoys finally reach climax together. They collapse onto the floor, exhausted but satisfied. The lead technician activates another control panel on his console, releasing a sedative gas into the air once more to ensure that they remain unconscious and under the Foundation's control.

*Dr. Allen turns to her colleagues with a satisfied smile. "Another successful containment override," she says proudly. "Our understanding of this species' reproductive behavior has grown immensely thanks to today's events."

The team spends the next several hours cleaning up the chamber, disposing of any biological waste, and returning everything to its original condition. Vladislav is placed back into stasis, his body monitored carefully by a team of researchers. The four decoys are taken away for further study and analysis, their bodies offering valuable insights into the inner workings of this incredible species.

As they prepare to move on to the next experiment, Dr.

Allen turns to Vladislav with renewed interest. "Well, well," she says softly. "Looks like our little friend here is starting to wake up." With a nod to her colleagues, she activates the intercom once more. "Subject appears to be regaining consciousness. Please continue monitoring him closely and report any changes immediately."

The team watches as Vladislav's eyelids flutter open, revealing pupils dilated with confusion and fear. He attempts to speak but no words come out;

his mouth feels dry and his limbs heavy from the effects of the sedative gas. The lead researcher quickly glances at a nearby terminal, monitoring Vladislav's vitals as they slowly begin to return to normal.

Dr. Allen leans in closer, studying Vladislav intently. "Well, it looks like our little friend here is going to be just fine," she says with satisfaction. "Now the real fun begins."

She turns back to her colleagues with a mischievous glint in her eye. "

We have so much to learn from him, don't we?" The team nods eagerly in agreement, their eyes fixed on the still-groggy Vladislav as they prepare for the next phase of research.
