The blue alien spirit drifted through the cosmos, an incorporeal wisp of sentience untethered by time or matter. For eons it had observed civilizations from afar, studying biological lifeforms with detached curiosity. Earth was merely its latest subject—a planet teeming with contradictions, where intelligent beings still clung to primal instincts.
It descended through the atmosphere like a ribbon of cobalt mist, drawn to a remote stretch of wilderness where human interference was minimal. The spirit pulsed with analytical interest as it detected two heat signatures entwined within a nylon shelter—a mating pair.
Observation before interaction, it reminded itself.
Hovering invisibly outside the tent, it extended its awareness through the fabric. The female's physiological readings spiked with exertion—elevated heart rate, dilated pupils, increased epidermal conductivity. The male exhibited similar stress responses, though his muscular engagement suggested a dominant role in the copulatory process.
Fascinating.
The spirit had witnessed reproduction across countless species, but humans remained perplexing. Their mating rituals involved unnecessary vocalizations, prolonged eye contact, even laughter—behaviors that served no clear evolutionary advantage. Yet here they were, persisting with baffling redundancy.
It needed direct access.
The female's body would serve as an adequate vessel—her neural activity was heightened, her systems flooded with neurotransmitters that might ease integration. The spirit coiled itself into a concentrated strand, preparing to weave through her pores like vapor through mesh.
Data awaited. Understanding beckoned.
The spirit moved.
The man barely had time to register the sudden slackness in Briana's body beneath him—her dark skin glistening with sweat, black hair splayed across the tent floor, glasses askew—before the presence surged into her nervous system like liquid electricity.
Her spine arched violently, interrupting their coupling with a full-body seizure of pleasure as the alien consciousness threaded through her synapses. "Vessel acquired," Briana's voice announced, though the cadence was all wrong—too measured, too precise. Her hands rose to examine herself, fingers tracing the sweat-slicked curve of her own waist with clinical detachment. "Human female. Late twenties. Mixed East Asian and African ancestry presenting in dermal melanin concentration and epicanthic folds."
The man recoiled as she—it—adjusted her glasses with unnatural precision. "Bri? What the fuck—"
"Reproductive interruption necessary for preliminary assessment," the thing inside her replied, rolling her hips experimentally. Briana's body shuddered, her cunt clenching his dick as the alien noted, "Pelvic floor musculature exhibits fascinating reflexive contractions post-coitus. Likely evolutionary retention to retain sperm."
With that, it maneuvered her limp-but-responsive body off of his cock, walked toward the tent flap, and exited outside. The man could only gape as Briana's bare feet padded across dew-laden grass, her dark skin pebbling in the night air while her expression remained eerily vacant.
The stolen hands rose again, this time to cup Briana's own breasts. "Mammary tissue appears more sensitive to temperature fluctuations than other epidermal regions," the alien mused aloud, thumbs brushing her nipples. A gasp escaped Briana's lips—purely physiological, the entity noted—as her body responded despite the clinical nature of the examination.
"Fascinating."
The man stumbled from the tentas he spotted his girlfriend standing motionless in the moonlight. "Bri? You okay?"
Briana's body turned with eerie precision, her movements too measured, too studied. When she spoke, her voice carried an odd cadence—her words, but not her rhythm.
"Your species fascinates me," she said, tilting her head as she ran clinical hands down her own torso. "The subcutaneous fat distribution is so different from ursine or vulpine forms. And these—" Her palms cupped her breasts, thumbs brushing the nipples. "Mammary glands remain engorged even without lactation. An evolutionary quirk, or purely for mate attraction?"
The man froze. "Bri, what the hell—"
She ignored him, fingers trailing lower. "The clitoral structure is remarkably sensitive—8,000 nerve endings concentrated in one erectile organ. Does that seem excessive to you? Or is the redundancy purposeful?"
"Stop—just stop!" He grabbed her wrists, but her body didn't react, didn't fight. Just stared through him with Briana's eyes gone distant.
"Fascinating," she murmured. "Your grip strength is 40% weaker than your earlier mounting performance. Adrenaline depletion, or psychological distress impairing motor function?"
He recoiled. "You're not her."
"No." Her head cocked. "But I am learning. Your turn now?" She reached for his waistband. "I require comparative data on male arousal thresholds."
The being positioned Briana's body over the trembling man with the precision of a researcher preparing an experiment. "Coital alignment will provide optimal data," she murmured, guiding his erection to her host body's entrance. "Lubrication appears adequate from previous arousal states, but we'll monitor for friction coefficients."
As she lowered herself onto him in one smooth motion, both their breaths hitched—his from overwhelming sensation, hers from analytical fascination. "Fascinating," she noted, pausing at full depth. "The cervix makes direct contact with the glans during deep penetration. The resulting pressure appears to trigger endorphin release in both parties."
Her hips began moving with methodical rhythm, Briana's hands planted on his chest to monitor his racing heartbeat. "Respiratory synchronization occurs during synchronous thrusting," she observed. "Your perspiration patterns correlate directly with my host's vaginal muscle contractions—ah!" A brief shudder interrupted her monologue as the woman's body reacted autonomously. "Interesting. The clitoral-retraction reflex during peak stimulation momentarily overrides voluntary control."
She adjusted the angle slightly, watching his face as she did so. "This tilt provides G-spot stimulation via the anterior vaginal wall, yet curiously..." She dragged a fingertip through the sweat on his collarbone. "Your adrenal response continues despite obvious pleasure. The human fight-or-flight instinct persists even during copulation."
The man gasped as her internal muscles fluttered around him. "Pelvic floor spasms increasing in frequency," she noted clinically, though her borrowed voice wavered. "Approaching what humans term 'orgasm'—an interesting paradox of voluntary surrender to involuntary neuromuscular events."
Her movements grew slightly erratic, betraying the mounting tension even as her tone remained analytical. "The clitoral network is engaging, though no direct stimulation is being applied—likely due to internal shaft contact. Muscle spasms imminent."
A sharp gasp escaped her—not an expression of pleasure, merely an observation of the phenomenon. "Orgasm commencing."
Her body arched, cunt clamping around him in rhythmic pulses, her face eerily composed even as her fingers dug into his shoulders for balance. "Strong myoclonus in the uterine and anal sphincter muscles. Norepinephrine spike confirmed via pupil dilation and flushed skin. Vocalizations appear... unavoidable." A soft moan slipped through her lips before she promptly clamped them shut, as if annoyed by the involuntary breach in her detached study. As the contractions subsided, she exhaled, tilting her head.
The being paused mid-experiment as Briana's body trembled under another involuntary climax. "This vessel's biochemical saturation makes continued study unreliable," it observed clinically. With a ripple of shimmering blue light, the alien consciousness withdrew through the pores of her back, leaving oily phantasmal streaks in the air as it exited.
Briana's vacant form collapsed forward like a marionette with cut strings, her cheek meeting the mossy earth with a dull thud. Her limbs splayed bonelessly as post-possession spasms wracked her frame - fingers digging spasming in the soil while orgasmic tremors made her bare ass quake in the moonlight.
"Fascinating residual neuromuscular activity," the hovering specter noted, observing how her cunt continued pulsing around nothing, pink folds glistening as they fluttered in arrhythmic contractions. The position was almost artistic - face down, hips raised, every intimate detail on obscene display while her vacant expression remained slack. A thin thread of drool connected her parted lips to the forest floor.
Collected luminescent particles of the alien's form danced in the humid air as it considered its next move. "Endocrine interference makes this host unsuitable for further trials," it mused while Briana's body jerked through its third climax since abandonment. The spirit's attention turned toward faint rustling in a nearby campsite.
