Reggie shuffled out of the back door of Grissom's Accounting, his thin shoulders hunched against the evening's persistent drizzle. The rain pelted his fur in tiny, cold daggers, but he barely registered the discomfort. A different sensation commanded his attention—the heavy, aching throb between his legs that had plagued him all day, growing more insistent with each passing hour until it became a maddening drumbeat of need.
He had noticed just how fattened and heavy they were when he had locked the door to his flat that morning, his balls just churning between his thighs, eager to unload. The feeling had stayed with him the entire day, through endless meetings and spreadsheets and water cooler conversations. 
His whiskers twitched in the damp air as he scurried toward the bus stop, tail dragging limply behind him. Another Friday night with no prospects. Another weekend alone in his musty apartment with nothing but internet porn and his right paw for company. The thought made his ears flatten against his skull.
The streetlights cast sickly yellow pools on the wet pavement, transforming puddles into portals of artificial sunlight. Each step Reggie took sent a jolt through his groin, his swollen testicles bouncing painfully between his thighs. He paused at the corner, waiting for the light to change. Water dripped from the end of his pointed snout, and he wiped it away with a paw that trembled slightly. Across the street, a female squirrel in a tight raincoat huddled under an umbrella. Reggie stared, mesmerized by the way the fabric clung to her curves. His mouth went dry. The light changed, and he forced himself to look away, shame mixing with desire in a nauseating cocktail.
By the time he reached his apartment building - a crumbling brick structure that had seen better decades - his fur was soaked through and his mood had plummeted even further. His paws fumbled with his keyring, the metal slippery in his damp grip. The keys jangled mockingly as he failed twice to find the right one.
"Fucking hell," he muttered, shifting his weight from one foot to the other. The motion caused his balls to swing heavily, reminding him yet again of the backed up, puffy feeling in his cords. He pressed his thighs together, the pressure against his orbs providing momentary relief.
As he stood there, wrestling with his keys and his libido, something else penetrated his awareness. There was a scent. He vaguely recognized it, though it wasn't exactly... familiar.  Unlike the usual smells of the building—mildew, boiled cabbage, and cat litter—this was something... else. Something that made his whiskers stand at attention and his nostrils flared wide.
Musky. Sweet. Female.
But not just any female scent. This was heady. Intoxicating. Exotic. It had a pungency that seemed almost... reptilian? Reggie's nose twitched rapidly, drawing in deeper whiffs. Each inhalation seemed to bypass his brain entirely, shooting straight down his guts and into his loins. His half-engorged member stiffened further, pressing urgently against the fabric of his cheap work slacks.
He turned his head, seeking the source. Three doors down, the apartment that had been vacant for weeks now showed a sliver of darkness. The door wasn't fully closed; it stood ajar by perhaps three inches, left open from someone who had gone inside. New neighbors?
Reggie swallowed hard. The sane part of his brain—the accountant part that calculated risk and consequence—told him to ignore it, to go into his own apartment and microwave some dinner and take care of his needs in private. But that voice was growing fainter with each breath of that mysterious, alluring scent.
His paws moved of their own accord, stuffing his keys back into his pocket. He glanced furtively up and down the hallway. Empty. The building's other residents were either still at work or already settled in for the evening. No one to witness his momentary indiscretion. No one to tell him not to do it.
"I'll just take a look," he whispered to himself, the words sounding hollow even to his own large ears. "Just to make sure everything's okay."
He crept toward the partially open door, his movements becoming more furtive and rodent-like with each step. The closer he got, the stronger the scent became. It was thick, almost syrupy in his nostrils, clinging to his sinuses and tickling deeply into his brain, in the same way that pepper did. His brain felt foggy, but in a fun way. He liked it. He wanted more.
At the door, he paused. It was dark inside, but he could hear soft sounds—a rustling, like something heavy sliding across itself. What was it? 
He placed a paw on the door and pushed gently. It swung inward without a sound, as if the hinges had been recently oiled. The gap widened, and the scent hit him full force—a wave of musk and sweetness that made his knees weak and his cock throb painfully in his pants.
"Hello?" he called out, his voice coming out more squeaky than he had hoped. There was no response, only that continued soft, constant rustling sound, maddening in its invitingness.
Common sense made one last desperate attempt to assert itself. This wasn't his apartment. He had no business entering. What if someone saw him? What if he got caught? He could lose his job, his reputation...
But his fat, aching balls overruled all logic. They had been denied too long, and the promise contained in that scent was too potent to resist.
Reggie slipped inside, pulling the door not quite closed behind him. The apartment was dimly lit by a single lamp with a red scarf draped over the shade. The walls were bare, the furniture sparse—just a threadbare couch, a low coffee table, and in the far corner, something he couldn't quite make out. A chaise lounge, perhaps? The air was noticeably warmer than the hallway, almost humid, like a terrarium.
"Hello?" he tried again, taking a few tentative steps forward. The carpet felt strangely plush beneath his feet, nothing like the cheap industrial carpet in the hallway. "I, uh, noticed your door was open. Just wanted to make sure everything was alright."
Lies. Even to his own ears, his concern sounded false, a thin veneer over raw, naked lust.
The rustling sound came again, followed by a soft hiss that might have been speech or might have been something else entirely. It came from the corner, from the shape that filled that entire side of the room.Reggie moved closer, drawn by the scent that now seemed to fill his entire being. His paws shook with need, his breath coming in short, shallow gasps. His erection strained painfully against his pants, a damp spot forming where the tip pressed against the fabric. Why was he so aroused? 
As his eyes adjusted to the dim light, details of the room came into sharper focus. But Reggie barely registered these details. His attention was fixed on the back wall and the figure that took up most of the space there, a figure whose outline seemed strangely fluid, continuously in motion despite appearing to lie still.
Another step, and another. Each brought him closer to the source of that maddening scent. The rational part of his brain had gone completely silent now, drowned out by the roaring of blood in his ears and the desperate throbbing between his legs. He found himself unbuckling his belt and unzipping his pants, his slacks sliding down his thighs and being left behind as he stepped out of them. He didn't care about how insane this was, all he cared about was that scent. His whiskers quivered rapidly, sampling the air, drawing in more of that intoxicating aroma. His pink tongue darted out to wet his lips, tasting the scent as much as smelling it. It coated the back of his throat like honey, sweet and thick.
When he was perhaps five feet from the figure, Reggie froze. His dick throbbed in the air in front of him, precum already drooling from the tip as his eyes, finally adjusting to the darkness, finally made out what he was seeing. There was movement, so much movement, the entire back of the room sinuously flowing around and over itself in shifting, mesmerizing knots and whorls. A soft chuckle emanated from the shadows, low and feminine and dangerous.
"Come closer, little one," a voice whispered, words sibilant and drawn out. "I've been waiting for a morsel like you."
Reggie's paws clenched and unclenched at his sides. The voice should have triggered alarm bells in his head, but it wasn't, and that was alarming him. It was all too predatory, too knowing, too perfectly lascivious. It was the voice of someone who needed Reggie to fuck them. Reggie stepped forward, his socked foot bumping into something warm, fleshy, and heavy. It caressed along his shin as he stepped past it. He could see more shifting shadows, thick swirling morasses of swirling flesh, and between them, in the center of them, voluptuous and welcoming and ready for him... was her.
She was massive, in all aspects. Even recoiling back against the wall, near the shrouded window, he was taller than him. Hints of light danced across iridescent scales, soft and glossy and slick. She shimmered, a massive serpent woman, her entire lower body a long coil of python, that was even now circling slowly around behind him. He didn't care about her lower body, though - it was her upper body that held Reggie transfixed. The snake had a woman's torso emerging from her serpentine form, skin a pale green that darkened at the edges like bruised fruit. And her breasts - dear god, her breasts - they were enormous, pendulous things that defied gravity, each one vulgar and plump, the soft, inviting bosom hanging to either side with a rich, slick sheen along the crevasse between them. The flesh of the snake's neck trailed down, glistening with a thick, clear substance that caught the light and broke it into tiny prisms.
Reggie's mouth fell open, his small pink tongue suddenly dry as sandpaper. The python-woman's face was beautiful, with high cheekbones, slitted yellow eyes rimmed with darker green scales, and full lips that curled into a knowing smile. A forked tongue flicked out between those lips, tasting the air, tasting him.
"Such a sweet little treat, and in such need," she purred, her voice a low hiss that seemed to bypass his ears and vibrate directly against his spine. "I can smell your lust from here."
As if to underscore her words, she shifted upwards, sitting forward, and her massive breasts swayed with the movement, clapping together with a sticky splat before pulling apart, the slimy trench beneath them peeling apart like the cheese from a fresh hot pizza. The motion released a fresh wave of her scent, THAT scent, the same intoxicating musk that had drawn Reggie into her lair. He watched, mesmerized, as the clear substance coating her breasts, thicker than sweat, more viscous than water and gathered in the deep crevice between them.
She noticed his stare and chuckled, a sound like scales sliding over silk. With deliberate slowness, she raised a hand, five long, delicate fingers tipped with curved black claws, and traced a path from her collarbone down to the swell of her left breast. The claw left a faint trail in the slime that quickly filled back in, like a finger drawn through honey.
"You like what you see, little rat, don't you?" she taunted, cupping the massive globe of flesh, lifting it slightly as if offering it to him. "I've been told my... nectar... has quite an effect on mammals like you..."
Reggie couldn't reply. His entire body thrummed with need, his cock so hard it ached. He was drooling continuously, gooey strands of precum splashing against his feet. His whiskers trembled, his nose working overtime to process the pheromone-laden air, his brain racing with the chemical fire of her potent musk.
The python-woman smiled wider, revealing teeth that were just a bit too sharp, a bit too pointed. She stretched languidly, her enormous body shifting before him, her coils unfurling to reveal a path between them, leading up to her, leading up to her sex.
"Come closer," she beckoned, crooking a finger at him. "Don't be shy. I promise I won't bite you." 
She giggled at her own joke, and the sound broke some part of Reggie's hesitation. He took a stumbling step forward, then another. His rational mind screamed warnings - predator, danger, run - but his body responded only to the primal call of her pheromones.
As he drew nearer, she leaned forward, and from her mouth flowed a warm, glistening, clear blob of mucus. It drooled over his chin and syruped in a long, sticky glob down between them. Reggie watched, transfixed, as it stretched into a long, viscous strand before finally breaking and splattering between them, disappearing into the cleavage of them.
The sight triggered something in Reggie, some deep-seated, animalistic impulse. A feral sound escaped his throat—half squeak, half groan. He stroked himself, urgently, his sleek pink rat length straining as hard as granite between his eager fingers as he stared at the glistening morass between her breasts. It was impressive for his small frame—pink, veined, and glistening at the tip. Below it hung his testicles, swollen and heavy with days of pent-up seed.
The python's eyes widened slightly, then narrowed with pleasure. "My, my," she hissed. "What a delicious surprise. And so... ready." Her gaze fixed on his engorged balls, and her tongue flicked out again, as if already tasting him. She raised her hands to her breasts and pressed them together, the slime between them squelching obscenely as it bulged out and over the top of her breasts, a bubble burping wetly out from inside the viscous goo. Then, with a deliberate motion, she dragged her claws down the inner slopes of both breasts, leaving momentary furrows in the slime. 
"My breasts just seem to make males crazy," she said conversationally, as if discussing the weather. "You probably can't even hear me, can you? No, of course not. My pheromones are triggering every reproductive instinct in that tiny brain of yours. It makes you forget all about self-preservation, and self-control." She tilted her head, studying him. "You have no idea, do you? You're too busy wondering what these would feel like against your face, around your cock..."
Reggie whimpered, staring at her massive, fleshy breasts. He nodded, not hearing a word she said, only knowing that she wanted him to breed her, and the only thing keeping him from ravishing her was his not knowing, exactly, how. All he could think about was burying his face between her magnificent breasts, feeling that slime coat his fur, his skin, his aching member. He wanted to bury himself deeply within her, in every way possible.
"Please," he managed to croak, the word barely recognizable.
The python smiled, triumphant. "Come on, then. Come, little rodent, and taste what you desire."
Reggie closed the final distance between them in a rush, finding himself collapsing on top of her. His paws had landed on the snake's soft, pillowy breasts, a tacky film skidding up under his wrist as his paws slid up over them. He ended up pushing her breasts away from each other, which revealed the slick, sticky crevasse between them. Up close, her scent was overwhelming. Rich, musky, sour and feminine with a pungent reptilian undertone that made his head swim. 
"Don't just touch them," she suggested, her voice dropping to a hypnotic whisper. "They're so sensitive. They want to be kissed. Licked. Tasted."
He needed no further encouragement. His paws kneaded, stroking and sinking into the soft flesh. The slime clung to his fingers, warmer than he expected, and surprisingly thick—like melted wax. It drooled down his wrists and forearms, and his nostrils flared as he took deep, heavy draughts of the pungent sweet scent.
"Oh god," he gasped, kneading the massive globes, the broad and jutting nipples sliding against his sticky palms with a wet sticky noise. He lifted up his left paw, and watched in fascination as the slime slowly sluiced down between his fingers.
The python arched her back, pushing her breasts towards him. "That's not nearly enough," she teased. "Don't you want a closer feel? Don't you want to taste?"
Before Reggie could respond, she reached out and gripped the back of his head, her claws pricking his scalp through the thin fur. With surprising strength, she pulled him forward, guiding his face between her breasts.
The slime enveloped him—nose, mouth, cheeks, forehead. It was in his fur, his whiskers, seeping into the corners of his mouth. He should have been disgusted, should have pulled away, but instead, he pressed deeper, his tongue darting out to lick at the viscous substance.
It tasted sweet and bitter at once, like overripe fruit on the verge of fermentation. The effect was immediate and devastating. His brain flooded with dopamine, endorphins, and other chemicals he couldn't name. Every inhibition dissolved, every caution evaporated. There was only need, desperate and consuming.
Reggie's hips thrust forward instinctively, his cock seeking any friction, any relief. He felt something smooth and cool touch his ankle, then slowly slide upward. In his pheromone-addled state, he registered only distantly that it was her tail, beginning to curl around his leg.
"Yes, that's it," the python crooned, her voice seeming to come from everywhere and nowhere. "Worship them. They're all yours."
Reggie's face was completely buried now, his desperate muffled groans vibrating against her flesh. He was drowning in sensation, in scent, in taste. His paws clutched at her breasts, squeezing and kneading with increasing frenzy.
The python's tail continued its upward journey, wrapping around his calf, then his knee, then his thigh. The pressure was gentle but insistent, a cool, muscular presence against his fevered skin. Reggie, lost in the haze of pheromones, barely noticed.
Reggie thrust his hips uselessly against her belly, his cock painfully hard and leaking constantly now. Sensing his desperation, the python shifted her lower body, parting the coils of her tail to reveal a glistening slit, pink and inviting amid the green scales.
"Is this what you need, little rat?" she teased, her voice a seductive hiss. "A warm, wet place to bury that desperate cock?"
Reggie pulled his face back from her breasts just enough to see what she was offering. His face was coated in slime, his eyes glazed and unfocused. He nodded frantically, beyond speech.
The python smiled, revealing those too-sharp teeth again. "Then take it. Take me."
With a feral cry, Reggie lunged forward, positioning himself between the coils of her tail. His slime-covered paws gripped the scales on either side of her slit, and with one desperate thrust, he buried himself to the hilt inside her.
The heat and pressure were exquisite, like nothing he'd ever felt before. Her interior muscles gripped him with unnatural control, rippling along his length in waves that threatened to milk his orgasm from him immediately. He threw his head back, a strangled sound of pleasure tearing from his throat.
"Yes," the python hissed, her own eyes narrowing with pleasure. "Yes, little rat. Give yourself to me completely."
Reggie began to thrust, his movements frantic and uncoordinated. Each plunge into her depths sent jolts of pleasure shooting through his entire body. His balls slapped against her scales, heavy and full, aching for release.
As he lost himself in the rhythm, the python's tail continued its stealthy ascent. It wrapped around his waist now, the pressure still gentle, a pleasant heaviness that kept his hips hilted against her loins. It slid up along his back, a heavy scarf along his shoulders, and his paws slid slickly along the snake's breasts, his face sinking down into the hot, sticky cleavage between them. She remained relaxed, her enormous breasts heaving slightly with each of his thrusts, jiggling shinily against her arms, but her lower body was increasingly active, the coils shifting and tightening around him.
"That's it," she encouraged, her voice honeyed poison. "Harder. Deeper. Don't hold back."
Reggie complied, slamming into her with reckless abandon. Sweat and slime mingled on his fur, creating a slick, fragrant mess. His whiskers were plastered to his cheeks, his eyes squeezed shut as he chased his release.
Her hand moved to the back of his head, bringing it down, warm slime oozing out of her mouth in a viscous cascade as she dragged his muzzle down into it. It felt like hot glue, bulging slickly up between his lips as he pressed his mouth into the gooey ooze. He nuzzled eagerly between her heaving breasts as she pulled him affectionately down into her resinous embrace. The python's tail completed another loop around his midsection, then began to constrict slowly. Reggie only felt a growing weight, not realizing that the serpent's tails were tightening around his legs and waist. The grip increased by increments so subtle that Reggie, in his pheromone-induced frenzy, didn't quite notice. His movements became more restricted, his thrusts guided now by her muscle control rather than purely by his own volition.
The tip of her tail, meanwhile, had begun a sinuous path between his legs, sliding past his rhythmically pumping buttocks. It curled underneath him, seeking and finding his swollen testicles. With delicate precision, it wrapped around the base of his scrotum, forming a tight ring that separated his balls from his body. The heavy eggs bulged, their cords stretching downwards as they were dragged further away from his body.
The sudden tension made Reggie gasp, his eyes flying open. For a brief moment, clarity broke through the pheromone haze. He lifted his head, slime oozing from his cheekbones and chin, his rodent muzzle caked with the thick slime. He squeaked as he felt the constriction around his balls, and complained at the strength with which she was tugging on them.
"W-wait," he stammered, his voice thick and slurred. "What are you—"
"Shhh," the python soothed, reaching forward to stroke his cheek with one clawed hand. "Don't worry about that. Focus on how good it feels. Focus on these..."
She pressed her breasts together again, with Reggie's face caught between them, and they flooded his snout with a fresh wave of slime oozed from her mouth, down over them and over Reggie's snout. The pheromones hit him anew, and his momentary clarity evaporated. His hips resumed their desperate thrusting, even as the python's coils tightened further, controlling his every movement.
The pressure around his testicles increased, pulling them away from his body. It wasn't painful, at least not yet, but the delicious tension built his arousal higher while simultaneously preventing his release. His body craved orgasm, but was unable to deliver.
"Please," he begged, not even sure what he was asking for. "Please, I need to -"
"Not yet," the python said, her voice suddenly harder, more commanding. "Not until I say so."
Her coils tightened further, squeezing his midsection, his thighs, his chest. The pressure was becoming difficult to ignore, even through the pheromone haze. Reggie's thrusts were completely controlled now, the python using her powerful body to move him like a puppet, in and out of her at her preferred pace. Down below, the tip of her tail coiled more tightly around his scrotum, stretching his balls to a painful degree. Reggie whimpered, caught between excruciating pleasure and growing discomfort, but his squeaks were muffled into the cloying salted goo that crusted between her pendulous breasts.
It coated his eyes, filling his nostrils, seeping into his mouth faster in a salty, pungent coating that clung to his taste buds. It tasted sweeter now, cloying, with a chemical undertone that burned the back of his throat. His lungs labored to draw breath through the thickening mask of phlegmy secretion. Panic flickered at the edges of his consciousness, a dull warning light almost entirely smothered by the chemical haze of arousal.
"More," the python woman crooned, her voice taking on a different quality. It was hungrier, less seductive and more nakedly... predatory. Her clawed hands pressed against the sides of her massive breasts, squeezing them together and crushing his head between them. The action caused another gush of slime to erupt from somewhere deep within the mammary tissue, this time shooting directly into Reggie's open mouth as he gasped for air.
He coughed and sputtered, his body attempting to reject the foreign substance even as his mind craved more of the narcotic pheromones it contained. The slime clung to the lining of his throat, thick and resistant to his body's attempts to expel it. He could feel it coating his sinuses, sliding down the back of his throat, filling spaces inside him that were never meant to be filled with anything but air.
Reggie tried to pull back, a primitive survival instinct finally piercing the erotic fog. But the python's coils had him locked in place, his body trapped in her sinuous embrace. His cock remained buried inside her, his balls stretched painfully away from his body by the tip of her tail. He couldn't retreat, couldn't advance, he could only remain exactly where she wanted him, servicing her with his increasingly oxygen-starved body.
"Are you enjoying yourself?" Her forked tongue flicked out, tasting the fear that now mingled with his arousal pheromones. "I think you are. You should continue enjoying yourself, little morsel, it's far too late for second thoughts now."
Reggie's eyes widened as understanding dawned. This wasn't just rough sex. This wasn't just kinky breathplay. This was predation, pure and simple. She was going to kill him. No, she was already killing him, and his body was still responding with desperate arousal, still seeking release even as his oxygen supply dwindled. Horror tried to dawn within him, but the rictus of horny, pheromone-addled lust would not release its grip on his urgently thrusting, needy body.
"Please," he managed to gasp, lips bubbling with slime as he crammed his snout into the dark, sticky crevasse of her breasts, "I can't - need to - breathe -"
The python's lips curled into a cruel smile. "What you need," she hissed, "is to give yourself to me, completely. In every way possible." Her coils tightened further, squeezing his ribs, restricting his already labored breathing and crushing him down against her, forcing his snout into the congealed slime that was already suffocating him. "Give in," she whispered, the words silky and hypnotic. "Give in to me."
Her hand gripped the back of Reggie's head, her claws digging into his scalp and drawing pinpricks of blood. She ground his face down, making sure he could not pull out from the treasure trove within her bosom. "There," she said, holding him firmly in place. "This is where you belong. Right between them, drowning in me."
The slime was everywhere now. His ears, his eyes, his nose, his mouth, his throat. It filled every orifice, the sticky glue congealing, breath bubbles getting caught against his tongue, the rat unable to push out his stagnant breath to draw in fresh air. His eyelids were glued in place, denying him sight, leaving him with only the overwhelming sensation of her flesh against his and the increasingly desperate throbbing of his trapped cock buried deep in her snatch. Reggie's lungs burned with the need for oxygen. His diaphragm spasmed, trying to draw breath but only sucking the increasingly gellid, sticky goo further down his throat.  Spots danced before his eyes, and his body thrashed weakly within the python's coils, but her grip only tightened in response.
"Having trouble breathing, little rat?" the python asked, mock concern in her slitted yellow eyes. He could not hear her, his body bucking, his balls throbbing in the grasp of her slender tail coil. "That's it," she encouraged, her voice seeming to come from miles away. "Struggle. It makes all of this so much more... satisfying."
Her tail pulled down, crushing and squeezing as it pulled over the end of Reggie's scrotum, his fattened eggs squeezed together before squirting up and out of the tail's grasp. Blood rushed back into the abused organs, bringing with it a pain so intense that Reggie's entire body went rigid. The freshly-emptied tail flashed like a whip, striking Reggie's stretched testicles with a sharp, calculated blow. Pain exploded through his groin, radiating outward in waves that would have made him scream had his mouth not been full of slime. Instead, a strangled gurgle escaped him, bubbling through the thick secretion in gooey rivulets.
"Oh, did that hurt?" the python taunted, watching the vibrations of his muffled sounds ripple through the slime coating her breasts. "Good. I want you to feel everything. Every. Last. Sensation."
She struck again, the very tip of her tail acting like a whip against the taut skin of his scrotum. The pain was exquisite, cutting through even the numbing effect of the pheromones. Reggie's cock jerked violently inside her, his body responding to the agony with a perverse surge of arousal.
Another strike. Another. The python developed a rhythm, lashing his balls with precise, cruel strokes that left no time for recovery between blows. Each impact sent shockwaves of pain through Reggie's oxygen-deprived system, driving him simultaneously toward the edge of consciousness and the brink of orgasm.
"Your little rat balls are turning such a lovely shade of purple," the python observed, her voice thick with sadistic pleasure. "So full, so aching to empty themselves. But not yet. Not quite yet."
Reggie was beyond hearing her words now, beyond understanding anything except the dual imperatives of his body: the need to breathe and the need to cum. Both seemed equally impossible, equally distant. The slime was hardening into a squidgy resin in his throat, his sinuses. There was no way to dislodge it, the rubbery, gelatinous plug sealing itself around his muzzle. No amount of coughing could dislodge it, and his lungs spasmed uselessly as it effort. His cock throbbed painfully, trapped in the vise-like grip of her internal muscles.
The python continued her merciless assault on his testicles, alternating stinging blows with cruel squeezes. Each new torment pushed him further into a haze of pain-pleasure that transcended conscious thought. There was very little of Reggie left to think about things, as he was beginning to black out, his squirming rodent body captured as it drowned in the snake's musk.
"I can feel you weakening," the python whispered, her lips close to his slime-covered ear. "Your thrusts are getting so shallow. Your heart is racing to pump blood that has less and less oxygen. You're dying." She licked a stripe through the slime on his cheek, tasting her essence. "That's when I'll let you cum. Right at the very end. Right as you're slipping away."
Reggie could feel himself fading. His extremities had gone numb, his goo-blackened vision had tunneled to a pinpoint. Still, his hips continued to haphazardly move, driven by instinct rather than conscious control. Each thrust used more of his precious oxygen reserves, but he couldn't stop himself. His body sought release with the last of its strength, knowing on some primal level that reproduction was its final purpose, its last chance to pass on his genes before its extinction.
The python sensed his approaching limit. He had merely seconds left.
"Now," she hissed, her voice dropping to a guttural growl, her tail slapping up against his balls with a stinging swat that nestled them up against his groin. "Now you may cum, little rat. Cum as you die. Cum, as you become part of me."
The relief of pressure combined with her command broke something loose inside Reggie. His oxygen-starved balls contracted weakly, sending a drooling ooze of thick, hot semen seeping into the python's depths. The orgasm was unlike anything he'd ever experienced, more like a dam failing then a volcanic eruption. It was a catastrophic release that bordered on agony.
The python threw her head back, her own pleasure evident in the arch of her spine and the flush that spread across her scaled skin. "Yes," she moaned, her internal muscles rippling around his spurting cock, milking every drop from him. "Give it all to me. Every last drop."
Reggie's hips jerked uncontrollably as his climax continued, pulse after pulse of seed emptying from his abused testicles. Each ejaculation depleted more of his already dwindling oxygen supply, his body burning the last of its resources in this final, desperate act of procreation. Darkness encroached from all sides, consciousness slipping away like water through cupped hands.
"Thank you for your contribution, little rat," she whispered, her paw caressing the back of his limp skull, the rat's body trembling and convulsing but no longer consciously attempting to escape. Her voice was almost tender. Almost. "I always like to give my meals a proper send-off before they make their final journey inside me."
With those words, her jaw began to distend, the bones separating with audible pops that Reggie, in his final seconds of consciousness, felt more than heard. The python's mouth opened wider, then wider still, stretching far beyond what should have been anatomically possible for her seemingly human upper body. Reggie could not see the gaping maw, the thick, viscous slime that drooled from the glands in the back of her maw, the slick and supple lips leading to a cavernous gullet that he would fit, oh so neatly, down inside. 
The python's coils shifted, repositioning Reggie's lifeless body. She lifted it away from her, Reggie's now-flaccid member withdrawn from her foaming, slick vagina. The separation caused one final, weak pulse of semen to dribble from his tip, dangling from the limp shaft in a pearlescent strand. 
She didn't notice, but she wouldn't have cared if she had. Fun time was over - now it was time to feast. She peeled the rat's limp head up away from between her breasts with a crackling, sticky sound. Goo clung to him, having congealed into a thick scab that clung in a yellowish clot around his mouth. A single bubble was trapped in the goop, by the rat's nose, his last gasp trapped in amber. 
Then, she lifted him to her maw. The first engulfment was quick, as she stuffed his head and shoulders between her gaping jaws in one smooth motion. Her throat muscles contracted around him, pulling him deeper with peristaltic waves. The slime that coated his body served as lubricant, easing his passage into her throat, stretching it in an open bulge.
The python's throat expanded to accommodate his shoulders, then his chest. The pressure was immense, crushing what little air remained in his lungs out through his mouth, the crusted slime bulging outwards like a frog's throat from the rat's snout. Reggie's ribs crackled under the strain, being forced inwards to allow the rat's torso to fit further down the snake's throat. Still, the python's powerful muscles worked, drawing him inexorably inward. The rat was, after all, meat, and meat needed to be devoured.
As Reggie's midsection entered her throat, the python experienced a new wave of pleasure. Her entire body shuddered with it, scales rippling in waves from head to tail. 
This was her true climax, a primal ecstasy of feeding, of conquering, of consuming another life into her own. Inch by inch, Reggie disappeared into the python's body. Slender belly, fleshy haunches, his dangling drooling dick, all disappeared between her lips. His swollen, bruised testicles, which had driven him to this fate in the first place, slipped past her lips and dragged along her tongue. 
Her torso distended with the shape of her meal. The bulge that used to be Reggie traveled slowly down the length of her, muscle contractions pushing him toward her stomach where digestion would begin in earnest. She stroked the lumpy outline of him through her scales as his thighs disappeared into her maw. It was a lover's caress for what was now simply food.
The python settled more comfortably back amongst her coils, which shifted and flexed along the sparse floor. They had their own bulges, bulges Reggie had never noticed. Other males who had found her door and followed their nose right down her throat. Five... ten? It was hard to know just how many she had gulped up. Her body filled the back of the room, and her body was filled with those lonely, disposable souls.
Her massive breasts, still glistening with their glaze of slime, rose and fell with her contented breaths. Already, her body was producing more of the irresistible secretion, preparing for the next victim who might wander past her strategically ajar door. She closed her yellow eyes, a satisfied smile playing across her lips. Her forked tongue flicked out, tasting the lingering pheromones and the faint trace of fear that hung in the air. She would rest here for a few days, feeding and digesting, and then move on to a new hunting ground. There were always more horny males, more desperate creatures driven by needs they couldn't control.
