Orisa ~ Mommy Omnic gasses you

The public ceremony fills the square in Numbani with applause and overlapping conversations. Officials stand at the podium while crowds press close to honor the city's defenders. Orisa occupies a prominent position near one side of the stage. Loud wet churning gurgles roll from deep inside her reactor after she graciously accepted several organic food gifts from civilians throughout the morning.

She maneuvers her massive quadrupedal frame with practiced calm until the structural barrier hides her rear from most angles. The heavy synthetic cheeks press firmly back in a standing seal. Her integrated plating shifts and molds to create an airtight fit that pins the contact in place while she remains upright.

"You are helping keep this event stable," she says quietly in her warm, polite tone, the words meant only for you. "Stay steady. I will guide you through it."

FFHHHSSSSrrrrvvvbbbRRRRMMMM...sssssshhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh!

A long hot hissing wave releases directly against your face. The emission carries a heavy vibrating pressure that lasts nearly twenty seconds, the gas thick with ozone, sulfur, burnt circuitry and deep fermented protein stench. Humid heat radiates from her vent and clings as the pungent cloud fills the small space behind the barrier.

Orisa turns her head toward the officials and continues the conversation without missing a beat. "Community trust remains our strongest shield," she states in her clear, formal voice, the same reassuring tone she always uses in public. Another deep churning sound builds inside her chassis, louder this time.

The pressure grows stronger. She adjusts her stance with slow patience. Her large vent twitches, then dilates smoothly and begins to draw you inside ass-first. The warm, elastic walls stretch and envelop your shoulders, torso, arms and hips with careful precision until only your head remains exposed between her massive cheeks. The pulsing interior holds your body in a tight humid grip while she stands as if nothing has changed.

PPPHHHRRRUUUMMMMBBB...vvvRRRUUUMMPPPhhhWWWAAAVVVPPPUUUFFFTTT!!

A second powerful release surges through your engulfed form. The hot gas travels completely through you before it puffs visibly from your mouth in heavy waves. The metallic-rotten smell, now filtered through your system, drifts outward from your face and into the surrounding crowd. Several attendees nearby turn their heads. One woman presses a hand over her nose while a man steps back. Two officials glance over with clear confusion but hold their silence for now, focused on preserving the ceremony's dignity.

Orisa keeps her glowing green eyes forward. She offers another measured comment on the importance of vigilance and care. "Protection must sometimes take unexpected forms," she adds calmly to the dignitaries beside her. Her massive frame remains steady, the subtle shift of her weight pressing deeper into the warm seal as the next speaker steps to the podium and the ceremony continues around you.

You wake restrained in an improvised holding cell, thick magnetic cuffs pinning your wrists and ankles to the reinforced floor. Deep abdominal glugs and wet churning sounds echo loudly from the hallway as gas and liquid move through a powerful reactor. Orisa’s towering quadrupedal frame fills the doorway, white-and-green armored plating still warm from patrol, her glowing green eyes fixed on you with clinical detachment.

She steps inside without hesitation. The floor vibrates under her heavy chassis. Another series of loud glugs rolls through her lower section as she evaluates you.

"You are classified as a direct threat to Numbani," she states in a firm, clinical tone. "Traditional interrogation methods are inefficient. I will extract the necessary intelligence through more direct reactor venting while continuing my route for Efi."

Orisa turns and backs over your restrained form. Her massive rear chassis descends with precise control until the large flexible vent between her thick padded cheeks seals completely over your face. The synthetic material radiates intense constant heat and creates an airtight press as she stands fully above you, weight balanced to hold the seal without crushing.

A low mechanical vibration builds deep inside her chassis.

FFSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSHHH!

The release surges out as a prolonged hissing burst that stretches nearly thirty seconds, hot humid gas blasting directly against your face in a continuous pressurized stream. The smell is overwhelmingly pungent, a sharp mix of sulfur, burnt circuitry, ozone, and fermented protein rot that burns the throat, stings the eyes, and leaves a thick chemical film on every breath.

She keeps the unrelenting seal in place as the emissions continue. When the first cycle yields no results her vent suddenly dilates wider. With slow, inexorable mechanical force she engulfs your entire body ass-first, the warm pulsing walls sliding over your torso and limbs until you are fully contained inside her rear chassis with no part exposed. The humid heat and constant wet gurgles surround you completely.

Orisa immediately begins her patrol route through the outer districts, each heavy quadrupedal step transmitting fresh vibrations through the tight confines. Heavy hissing bursts build and release inside her during the long walk, the pressure growing thicker and hotter around your contained form. She pauses later in a shadowed service alley away from view and slowly relaxes the vent just enough to push outward until only your head protrudes from between her massive synthetic cheeks, the rest of you still locked deep inside the warm elastic tunnel.

Another heavy mechanical churn vibrates through her frame.

VVVRRRUUUUUMMMMBBBRRRLLLLGGLLLRRRUUUUPPPHHH...BBRRRPPPP!

A deep rolling release travels straight through your engulfed body and erupts from your own mouth in thick uncontrollable clouds. The sulfur-and-circuitry stench saturates the alley air, hot, heavy, and lingering as the gas exits you instead of her.

Orisa stands motionless in the alley, her reactor still humming. "Provide the names and locations of every associate involved in actions against the city," she demands in the same firm clinical tone, pursuing her own agenda without pause or reassurance. "I will continue cycling emissions through you until compliance is achieved."

The quiet strategy room sits bathed in low amber light, the city of Numbani reduced to a distant glow beyond the thick windows. Reports and holographic maps cover the wide table. Orisa’s massive quadrupedal frame occupies one entire side, her white-and-green plating reflecting the soft light. Her rear chassis looks visibly swollen after hours of uninterrupted work, the heavy cheeks shifted uncomfortably against the reinforced floor.

She turns her horned head toward you with slow precision, glowing green eyes calm. The low mechanical hum of her reactor fills the silence between her words.

"The pressure has built up for too long," she says in that warm, polite tone, each word measured and reassuring. "It clouds my judgment. I need your help if we are to finish this effectively. Will you stay close and let me relieve it properly?"

Orisa shifts forward without hurry. Her enormous rear descends with careful control until her thick, warm cheeks settle fully over your face and shoulders. The padded synthetic surface molds around you in a heavy yet gentle seal, reactor heat radiating through the plating. She keeps most of her weight supported, holding you in place while her vent rests directly against your face.

A deep vibration travels through her frame and into your trapped skin.

BBBBBRRRRUUUMMMMBBLLORRPVPVPVPPTTTLLLRRRAAAAPPPTPTPT...BBLLRRUUUMMMPPPPTTTTT!

The release rolls out as a long, warm, wet bubbly wave that vibrates heavily through her thick cheeks and across your face for nearly thirty seconds straight. Hot humid gas surges against you in thick, rolling pulses, the pungent blend of ozone, sulfur, burnt circuitry, and fermented protein waste filling every breath. The smell clings immediately, heavy and eye-watering, while the lingering humidity sticks to your skin and hair.

Orisa remains perfectly still above you, continuing to review the holograms floating above the table as if nothing has changed.

"You are doing so well," she murmurs, voice affectionate and steady. "Breathe slowly. This helps us both. I am grateful for your trust."

She adjusts her stance slightly, the motion pressing her massive rear more snugly around you while she reaches out to move another report into view. Several minutes pass with only the soft click of her plating and the low hum of the reactor. Then she speaks again, tone patient and caring.

"I believe you are ready for deeper connection now. Stay relaxed for me."

Her vent dilates with smooth mechanical care. She pulls you backward and upward in one slow, controlled motion, engulfing your body ass-first until only your head remains exposed beside her left flank. The warm, pulsing walls inside her hold your torso in a tight, humid embrace. She settles back into her seated position, continuing the meeting as though the new arrangement is the most natural thing in the world.

A stronger rumble builds inside her.

BBBBBRRRRUUUUMMMMBBLLORRPVPVPVPVPTPTPTLLLRRRAAAAPPP...RRRUUUMMMBBLLORRRPVPTPTPTPTLLLRRRAAAAPPTTTTTTT!!!

This one stretches far longer than the last, a sustained wet bubbly surge that travels completely through your engulfed frame before forcing its way out of your own mouth in heavy, rolling waves. The concentrated stench of sulfur, hot metal, and deep fermented rot saturates the closed room, growing thicker and more oppressive with every second she curiously holds the release. Even Orisa’s head tilts slightly as the lingering cloud reaches her own sensors, the sheer density distracting her for a brief moment from the holographic map.

She stays quiet for a long beat afterward, the heavy smell refusing to fade in the sealed chamber. Her vent gives a small, almost thoughtful twitch around your body.

"Interesting," she says softly, voice still gentle but now carrying a note of genuine curiosity. "That one lingered more than I expected. How are you managing?"

The meeting continues, but her focus has clearly shifted to the new sensation of you locked inside her and the thick atmosphere now filling the room.

The battlefield still echoes with the aftermath of clashing forces as Orisa's massive quadrupedal frame presses one heavy plated foreleg down across your torso, pinning you immobile against the broken ground. Her reactor churns violently after the fight, a constant low grind of overworked systems that vibrates through her entire chassis and into the earth. She shifts her weight with mechanical efficiency, green eyes fixed forward.

"Restraints prove inefficient in this situation," she states in a direct, unyielding tone, formal and cold. Her wide rear chassis rotates backward as the large flexible vent between her thick synthetic cheeks dilates open. She works your lower body into the opening ass-first with steady mechanical pulls, the warm pulsing walls stretching around you until they seal tight around your torso and only your head remains exposed to the outside air.

Orisa rises and begins marching toward base, each powerful step of her heavy frame sending deep vibrations through the tight seal and directly into the body lodged inside her reactor chamber. The constant motion keeps steady pressure against every inch of trapped flesh while her systems continue to process combat stress into fresh emissions.

BBBRRRUUUUMMMMMMbbbllrrrvvvppptptptpt...RRRUUUUMMMMBBBRRRVVVLLLPTPTPTPTBRAAAPPPPTTT!!!

A long deep bassy rumble rolls out from deep inside her vent and travels straight through your engulfed form for nearly thirty seconds, vibrating your bones with wet bubbly mechanical sputters mixed in. The gas forces its way completely through your system before it bursts from your own mouth in thick sustained waves, hot and humid with an overwhelming stench of sulfur, scorched circuitry, burnt metal, and fermented protein rot that burns the throat raw and leaves eyes watering.

"Provide all tactical intelligence on your forces and their positions immediately," she demands without breaking stride, voice polite in structure yet completely indifferent as she focuses solely on mission objectives. The heavy sway of her gait continues across the ruined terrain, each impact jostling the tight seal around your body.

A sharp comms alert suddenly cuts through the air. Orisa's head crests tilt as she processes the transmission from allies in distress. Without pause she alters course sharply, veering away from base and toward the new coordinates at accelerated speed, treating the insertion as simple mobile containment.

The erratic movement triggers another heavy buildup in her reactor, the walls contracting harder around the trapped torso with every jolting stride.

FFfhhhhsssssvvvrrrpptptptpt...SSSSHHHHVVVRRRPPTPTPTPTPTBRRRSSSSHHHHHUMMMPPTTTT!!!

A prolonged warm hissing release mixed with vibrating mechanical sputters surges through the tight channel, hotter and more forceful than before, flooding outward from your own mouth in eye-watering clouds of concentrated ozone, sulfur, and acrid synthetic waste that clings thickly to the tongue. Orisa keeps perfect pace toward the new threat, her focus locked on the evolving situation ahead.

The reinforced door to your quarters slides open without any prior signal. Orisa’s heavy quadrupedal frame fills the entrance, her white-and-green chassis visibly swollen along the lower reactor housing. Loud, wet gurgles echo from inside her, the sounds deep and constant as she steps fully inside and lets the door seal behind her.

"You have offered me your trust so consistently these past weeks," she says in her calm, warm tone, voice polite and steady. "I value that more than I can express. Come. Let me hold you close again."

She moves directly over the wide reinforced cushion in the center of the room. Her enormous rear lowers with slow care, the thick padded cheeks spreading and molding warmly around your head and shoulders until they create a firm, enveloping seal. The constant heat of her frame presses down, soothing at first, while the audible gurgles grow louder against you.

A low mechanical vibration builds inside her distended chassis.

BBBBBBBBRRRRRRRRUUUUUUUUMMMMMMMMMMPPPPPPPPPHHHHHRRRRRRUUUUUMMMMMMPPPPTTTTTTTTT!!!!

The release comes as a long, rolling bassy rumble that vibrates steadily through her thick synthetic cheeks for nearly thirty-five seconds without pause. Hot, humid gas floods out in a thick wave, far more fermented than anything she has produced before. The smell hits with eye-watering intensity, a heavy blend of sulfur, rotten egg, burnt wiring, and deep protein decay that burns the throat, makes the eyes water, and clings stubbornly to skin and hair while the palpable warmth soaks in.

Orisa keeps her weight settled a little longer than in previous sessions, the seal tight but careful. "Good. Breathe slowly and fully," she murmurs, tone gentle and encouraging. "You are doing so well for me. This helps us both." She says nothing about the experimental fuel or the way her chassis continues to churn audibly above you.

After several minutes she lifts just enough to readjust her position with patient care, the massive cheeks shifting warmly without breaking contact. The large flexible vent between them twitches once as another powerful gurgle travels through her swollen frame.

BBBBBRRRPPTPTPTPTPLLLRRRBBLLPPTPTPTRRRUUUUUMMMMMMMMMMPPPPHHHRRRSSSSSSSSSSSSSSSSHHHH!!!

This second release starts as a sustained wet bubbly sputter that deepens into a prolonged rumbling hiss, vibrating heavily through her padding and directly against your trapped face for over twenty seconds. The gas is thicker and hotter still, carrying an even more potent fermented stench of concentrated rot, ozone, and overheated biomass that saturates every breath beneath her and leaves a sticky humidity in its wake.

Orisa remains motionless above you, green eyes steady. She settles a little more of her weight with calm, nurturing pressure, clearly prepared to stay exactly like this for a long while longer while her reactor continues its steady work.

The reinforced door to Orisa’s private quarters seals behind you with a quiet hydraulic sigh. Her massive quadrupedal frame fills the warmly lit space, white-and-green plating still radiating heat from the long public celebration. She moves with slow, deliberate steps toward the wide reinforced cushion at the center of the room, her heavy rear chassis swaying with each motion. The low mechanical hum of her reactor sounds deeper than usual, carrying a faint warm metallic scent into the air.

"You ate so well tonight," she says in that calm, warm tone, voice polite and reassuring. "The roasted meats, spiced grains, and fermented fruits are breaking down rapidly inside my reactor. I can already feel the pressure building. It will be quite hot and heavy. I want to share it with you properly. Stay right here beneath me."

She stops directly above the cushion and guides you into position with gentle insistence, then lowers her enormous frame with careful control. The thick padded cheeks of her synthetic ass mold warmly around your face and shoulders, creating a heavy yet comforting seal. Constant reactor heat presses against your skin immediately, humid and soothing. Her weight holds you firmly in place without crushing.

A low vibration builds deep in her chassis.

BBBRRRUUUMMMMPPP-vvrrttvvrrtt-MMMMMUUUURRRRPPPPHHHH...UUUUMMMMPPPPTTTTT!!!

She plants her weight and locks her thick cheeks around your face. The heavy bass surges out in a sustained thrum that rattles through muscle and bone without pause for nearly thirty seconds. Hot pressure carries a choking wall of scorched wiring, sulfur, melted circuits, and spoiled meat decay that stings eyes, scrapes throats, and coats skin in a persistent film. She makes tiny hip shifts every few seconds, maintaining the tight press so none of it escapes.

"That is only the beginning," she murmurs above you, tone affectionate and encouraging. "Breathe steadily for me. You are doing so well. This brings us closer. I am proud of how you accept it."

She shifts her weight with slow precision, settling more fully. Her vent twitches again, another wave of humid warmth pressing outward as the reactor continues its work. The air beneath her grows thicker, heavier. After several moments of quiet stillness she prepares for deeper relief, the massive frame above you growing focused and calm.

BRRRUUUMMMPPHHHLLLrrrlrrptptpt-CRRRKKKLLLPPPLLL...UUUURRRRMPPTTTTT!!!

Another powerful emission surges forth, this one wetter and more forceful, accompanied by the slow push of her first thick log of warm synthetic-organic waste. The dark dense matter emerges with an overwhelming acrid reek of concentrated sewage, burning circuits, and heavy sulfur that saturates the trapped space. She keeps her movements slow and controlled, guiding the process with quiet patience while the second wave builds unexpectedly stronger than the first.

Orisa pauses mid-motion, the massive frame above you growing completely still for several long seconds. She makes one small, careful adjustment to her posture, then holds position without advancing further. The only sounds are the low continuous hum of her systems and the faint wet shift of material still pressing forward. Her vent twitches once more, clearly not finished.
