Chapter 13: The Professor's New Invention
The next evening, the heavy silence of the professor’s study felt different. It was expectant, charged like the air before a summer storm. The three of them sat amidst the leather and parchment, cradling cups of smoky Lapsang souchong. The previous day’s catharsis had settled into a comfortable, knowing intimacy. Chris felt it in the way Bea’s foot rested against his ankle, in the way Professor Blackwood met their eyes without a trace of academic remove.
“I’ve been thinking,” Blackwood said, setting her cup down with a precise click. “About resolution, and… escalation. The Satiate was a conclusion. But desire isn’t linear.” She reached for a leather satchel beside her chair and withdrew two objects, placing them on the low table.
They were pumps. But unlike any medical device. One was the familiar brass-and-glass cylinder Chris had experienced, its surface now etched with more intricate, looping sigils that seemed to drink the dim light. The other was new—a dual-chambered apparatus of blown glass and polished rosewood, shaped with an unsettling, organic curvature.
“A refinement,” Blackwood said, her finger tracing the glass. “For her. And for me, should the mood strike. They don’t just amplify size. They amplify capacity. For sensation. For giving. For taking.”
Bea leaned forward, her curls catching the firelight from the hearth. “Capacity?”
“To hold more pleasure. To become more… receptive. Insatiable, in the best way.” The professor’s gaze was luminous. “I’ve paired them with a new prototype. I call it the Nymph’s Nectar. It doesn’t just lower inhibitions. It… articulates a deeper appetite. A purer focus on the act of consumption.”
Chris’s cock, which had softened to a semi-resting state, gave a definitive throb against his thigh. The memory of the pump, of the overwhelming fullness, was visceral.
“What’s in it?” he asked, his teacher’s mind still seeking the syllabus.
“The essence of compelled devotion,” Blackwood said simply, as if listing a common ingredient. “It brings a certain… mythological focus to the forefront.” She opened a small ivory box. Inside, on a bed of black velvet, lay three lozenges the color of venous blood, speckled with gold. “It’s safe. I’ve tested the base components. The effect is temporary. But it is profound.”
Bea didn’t hesitate. She took one. Chris, after a shared glance with her—a look that held their entire adventurous pact—took another. Blackwood took the third.
They placed the candies on their tongues simultaneously.
The taste was not sweet. It was metallic and deep, like licking a cold, ancient coin, followed by a bloom of pomegranate and clove. The effect was not a slow warmth, but an immediate, seismic shift in perspective.
For Chris, the world sharpened, but his focus tunneled. The firelight seemed to coalesce on Bea and the professor. Their shapes became archetypal. Bea was not just his wife; she was a creature of lush, hungry curves and knowing eyes. Blackwood was not an eccentric chemist; she was a poised, ancient mistress of secrets. His own body felt like an axis, a focal point around which their attention irresistibly swirled. His erection returned, not as an ache, but as a commanding, central fact of existence.
The change in the women was visible. Bea’s pupils swallowed the green of her irises, leaving pools of dark, hungry intent. A subtle, predatory grace infused her movements as she stood. Blackwood’s usual briskness melted into a slow, luxurious sensuality. They didn’t speak. They shared a look, a silent communication that bypassed language. Their purpose was singular.
“The rug,” Blackwood murmured, her voice a husky contralto. “By the fire. The light… it should play on the oil.”
Bea was already moving, pulling the thick Persian rug closer to the hearth. The fire popped, casting long, dancing shadows. Blackwood produced a large, crystal bottle filled with amber oil that smelled of sesame and exotic florals.
“Chris,” Bea said, and his name was a prayer and a command. “Lie down.”
He obeyed, settling onto the soft wool, the fire warming his side. His cock stood straight up, rigid and already leaking. Bea knelt at his feet, Blackwood at his head. They began to undress him, not with playful haste, but with a deliberate, ritualistic slowness. Their fingers, cool and deft, pushed his shirt open, slid his trousers and underwear down his hips. The air caressed his naked skin, but it was nothing compared to the heat of their gaze.
Blackwood poured a stream of oil into her palms, rubbing them together. She started at his chest, smoothing the slick warmth over his pectorals, down the tight plane of his stomach. Her touch was firm, possessive. Bea took more oil, coating his legs, his thighs, her hands slipping behind to knead the muscles of his ass. They were anointing him.
Then their hands converged on his cock. Two sets of slick, warm palms encircled his shaft, sliding from root to tip in a unified, slow stroke. Chris cried out, his hips bucking off the rug.
“Shhh,” Bea cooed, her breath hot near his hip. “Just receive. You’re the altar.”
The professor leaned down, her lips brushing his ear. “Watch what you do to us.”
They took the pumps. Bea, with a focused reverence, fitted the brass cylinder over Chris’s oil-slicked erection. The seal was tight, perfect. She worked a small, engraved lever. A deep, resonant hum filled the air, the sigils flaring with a gentle golden light. The suction was immediate, intense. Chris gasped as his flesh was drawn outward, expanding, thickening under the transparent glass. He watched, mesmerized, as his own cock grew, becoming monstrous, veined, and gloriously sensitive. Every nerve was a live wire.
Simultaneously, Blackwood arranged the dual-chambered device. One glass cup she placed over Bea’s exposed pussy, the other over her own. They knelt on either side of Chris’s swollen shaft, their legs spread. Another lever clicked. The same hum, a harmonic twin to the first. Both women gasped, their backs arching.
Chris could see it. Through the glass, Bea’s labia, already dark and full, were being drawn outward, swelling, becoming plump, glossy petals. Her clit, engorged, pressed against the glass like a tiny, eager pearl. Beside her, Blackwood’s more modest folds were undergoing the same transformation, becoming lush, open, and glistening wet. The pumps weren’t just enlarging; they were perfecting, sculpting them into hyper-sensitive, hungry versions of themselves.
Bea’s eyes, pitch black with desire, locked on his. “Look at what you’ve made us into,” she whispered, her voice dripping with a wanton hunger that was entirely new. “Look at these greedy, empty cunts.”
The pumps released with a soft, pneumatic sigh.
What was revealed was obscene. Chris’s cock was a thick, heavy pillar of oiled flesh, straining upwards, the head an angry purple. Bea’s pussy was a swollen, glistening bloom, her inner lips pouting, dripping a clear thread of arousal onto the rug. Blackwood’s was a mirror image, a slick, roseate invitation.
The succubus candy had fully claimed them. Their love was there, in the tenderness underneath the frenzy, but it was channeled through a filter of pure, devouring appetite.
“Now,” Professor Blackwood commanded, and they moved as one.
Bea straddled his thighs, lowering her dripping cleft onto the massive head of his cock. She didn’t slide down slowly. She impaled herself, taking him in one brutal, sinking motion. Her head flew back, a raw, screaming groan torn from her throat as she was stretched wider than ever before. “FUCK! Oh god, Chris, it’s splitting me open!”
She was so tight, a scorching, velvet vise around him. The oil allowed movement but did nothing to diminish the shocking, full sensation. She began to ride him, her hips pistonning up and down, her swollen lips dragging against his shaft with every stroke. “Yes! This! This is what I needed! This massive, beautiful cock!”
Blackwood, meanwhile, had positioned herself over his face. She lowered her dripping, pump-enhanced pussy onto his mouth. “Worship it,” she growled, and it was not a request. Her scent, musky and deep, flooded his senses. Her folds were heavy against his lips. He obeyed, his tongue lashing out, spearing into her depths, fucking her with his mouth as her hips ground against his face. She tasted of the candy, of her own unique salt, of pure power.
Bea leaned forward, bracing her hands on his chest. Her bouncing breasts were slick with oil. She captured Blackwood’s mouth in a savage, greedy kiss above him. Chris was trapped in the most exquisite prison: his cock buried to the hilt in his wife’s frantic, gripping heat, his mouth full of the professor’s demanding flesh, the sounds of their wet, open-mouthed kisses and filthy, overlapping moans drowning out the crackle of the fire.
“Touch yourself,” Bea snarled at Blackwood, breaking the kiss. “Make yourself come on his tongue. I want to feel you clench around him.”
Blackwood’s hand slid between her own legs, her fingers finding her engorged clit. She rubbed hard, fast circles, her thighs trembling around Chris’s head. Her moans became short, sharp cries. “There! Oh, right there, you glorious man! Make me come!”
Her orgasm was a flood. Chris felt her walls spasm around his tongue, a gush of hot fluid coating his chin and neck. The convulsions made her grind harder against his face, muffling his own groans.
Bea felt it too, through the intense connection of their joined bodies. “Yeah, come for him, you brilliant bitch,” she chanted, slamming down on Chris’s shaft with renewed ferocity. “Now me. I want his seed. I want to drink every drop. Give it to me, Chris. Fill this hungry cunt!”
The pressure, the overwhelming sensations, the sight of these two transformed women using him for their sublime consumption—it shattered his control. With a roar that was partly muffled by Blackwood’s flesh, he erupted. His release was catastrophic, pumping into Bea in thick, relentless jets. She screamed, her own climax triggered by the feel of him pulsing inside her, her internal muscles milking him in ragged, desperate pulls.
She collapsed forward onto his chest, Blackwood sliding off his face to lie beside them, panting. They were a slick, steaming tangle of limbs on the oil-darkened rug, the firelight dancing over their spent forms. Chris’s cock, still semi-hard, slipped from Bea with an obscene, wet sound.
The sound was a punctuation mark in the humid silence. Bea shuddered atop him, her breath hot against his neck. “Don’t move,” she whispered. “Not an inch.”
A strange, heavy lassitude held them, but it was deceptive. Chris became aware of a deep, persistent thrumming in his groin, a residual energy that refused to dissipate. His cock, lying spent against his stomach, felt alien—thick, heavy, and oddly sensitive, the skin stretched taut. It wasn’t softening. It was merely resting.
Beside them, Professor Blackwood propped herself on an elbow. Her gaze, now clearing from its carnal fog, was analytical again. She studied Chris’s shaft, then Bea’s glistening, parted thighs. “Fascinating,” she murmured. “The Nymph’s Nectar has a longer half-life than I calculated. The tissues are holding the enhanced state. The arousal is… suspended, not concluded.”
Bea slowly pushed herself up, looking down between her own legs. She ran two fingers through her slickness, then gasped. “Christ, I’m still so puffy. I can feel everything. The air, the rug… it’s all too much.” She looked at Chris, her eyes wide with a dawning, hungry realization. “You’re still huge. You’re just… waiting.”
The observation cut through the lethargy. Chris looked. She was right. The pump’s work was still visibly present, a monument to their earlier ferocity. The need, which had crested, was now circling back, hungrier for the novelty of this sustained, inflated state.
Blackwood moved with sudden purpose. She reached for the discarded pump, the sigils now dull but still potent. “The principle is sound. The channels are open. We should… explore the sustained plateau.” Her voice was low, inviting. “The stimulation will be profound. A feedback loop of constant enhancement.”
Bea’s answer was to take the pump from her hands. Her movements were fluid, reverent. She knelt between Chris’s legs, her swollen labia brushing his thighs. “Let’s see how big you can really get,” she said, her voice a mix of wonder and filthy intent. She fitted the cold brass ring over the root of his semi-hard cock. It was already so thick she had to work it on.
She pumped the lever.
The soft hum returned. Chris arched off the rug, a strangled shout caught in his throat. The sensation was sharper this time, more intense because his nerves were already singing. He watched, hypnotized, as the glass cylinder filled anew. His flesh expanded, stretching beyond its previous size, the veins rising in bold relief like topography on a monstrous map. The head mushroomed, flushing a deeper, more violent purple.
“My god,” Blackwood breathed, her hand drifting to her own pumped and tender flesh. She was watching Bea, not Chris.
Bea released the vacuum. What sprung free was absurd. Comical. Awe-inspiring. Chris’s erection was a true obscenity, a pillar of meat that seemed to defy the physics of his slender frame. The sensitivity was paralyzing; every heartbeat was a pounding throb of pure, raw feeling.
Without a word, Blackwood offered Bea the dual-chambered device. Their eyes met, a silent transaction of understanding. Bea took it. She positioned one glass cup over her own aching, protruding folds, and with a glance of permission, placed the other over Blackwood’s. The professor leaned back, bracing herself on her hands, offering her splayed flesh to the machine.
Bea worked the lever. The hum doubled. Both women cried out in unison, their bodies bowing as the suction pulled at their most sensitive, already engorged tissues. It amplified everything—the wetness, the heat, the desperate, empty need. When Bea released it, they were both gasping, their softened states gone, replaced by a hyper-real, glossy and gaping hunger.
“Now,” Bea panted, scrambling. She didn’t mount him. She turned, presenting herself to Chris on her hands and knees, her round, oil-slicked ass high in the air. Between her spread cheeks, her pumped cunt was a glistening, dark pink flower, utterly exposed and inviting ruin. “From behind. I want to feel every inch of that monster. I want it to hurt so good.”
Chris moved behind her, his massive cock like a weight he had to steer. He nudged the broad tip against her entrance. It seemed impossible. She was open, but he was larger than anything. He pushed. Her body resisted for a searing second, then gave way with a wet, tearing sound that was all fluid and stretched tissue.
Bea screamed, her fingers clawing at the rug. “FUCK! Yes! More!” He sank deeper, an inexorable invasion, her inner walls clutching in frantic, rippling waves around the impossible girth. He was splitting her in the most perfect way. When he was fully sheathed, they both froze, overwhelmed by the full, distended feeling.
Blackwood slithered around to face Bea. She kissed her, deep and messy, then looked down at where they were joined. “Beautiful,” she whispered, her own pumped sex dripping. She began to touch herself, her fingers circling her swollen clit, her eyes fixed on the spectacle. “Fuck her, Chris. Make her scream for me.”
He pulled back and thrust, a slow, devastating stroke. The drag was incredible, a hot, tight friction that made him see stars. Bea sobbed into the rug, her words slurred. “Don’t stop… don’t you dare stop… it’s so full…”
He settled into a rhythm, each thrust a deliberate, pounding conquest. Blackwood’s breathing hitched, her fingers working faster in time with his drives. “I can see every inch of you stretching her,” she moaned. “I can see her cunt clinging to you. It’s magnificent.”
The pumps had done their job too well. Every sensation was amplified, echoing, building in a loop that had no exit. Chris felt his second climax coiling, a tense spring in his gut. Bea was chanting a raw, broken litany. “Gonna come… gonna come around this giant cock… fill me up, feed me…”
Blackwood came first, a silent, shuddering release, her fluids spilling over her own frantic fingers. The sight of it, the smell of her added musk, tipped Bea over. Her internal muscles clamped down in a vicious, rhythmic milking that felt like being swallowed by a living vice.
It was too much. Chris’s control snapped. With a guttural roar, he slammed home and erupted. The orgasm was less a release than a total systemic surrender, pumping his essence into her convulsing depths in what felt like an endless flood. He collapsed forward over her back, his monstrous cock still locked inside her pulsed, both of them trembling violently. Blackwood lay beside them, spent, her hand still resting on her glistening mound, a serene, satisfied smile on her lips.
Blackwood lay beside them, spent, her hand still resting on her glistening mound, a serene, satisfied smile on her lips.
Chris felt Bea pulse around him, a final, fluttering aftershock that wrung a whisper from them both. He remained buried in that incredible heat, allowing the sensation to echo through his oversized, sensitive flesh. He stirred slowly, a minute shift that made Bea gasp and clench.
“Easy,” she breathed, her voice ragged against the rug.
He withdrew with a slick, drawn-out sound, his cock leaving her stretched and glistening. The cool air of the study hit the wet skin, a shocking contrast. He turned his head, his body still thrumming with the Nymph’s Nectar’s persistent buzz, and took in the view of Professor Blackwood.
She watched him, her eyes half-lidded. She was a sprawl of elegant limbs and soft curves, her usually sharp angles rendered vulnerable and open. The pulse at the base of her throat beat a rapid, visible rhythm. Without a word, Chris reached for the crystal bottle of oil.
“Your turn,” he said, his own voice rough with use.
He poured a generous pool into his palm, letting it warm before smoothing it over her stomach. She shuddered, a delicate tremor that betrayed her calm exterior. He worked the oil down her hips, over the pronounced curve of her pelvis, coating the thatch of dark hair now plastered wet and dark against her skin.
He took his own shaft, still impossibly full and heavy, in his oil-slicked hand. He slid it slowly, deliberately, through the slickness he’d painted on her lower belly. The sensation of her warm skin and coarse hair against his oversensitive crown was almost too much. A low groan escaped him.
“Use it,” Blackwood murmured, her legs falling open wider in clear invitation. Her pumped flesh, still plump and glossy, glistened under the firelight. “Don’t tease.”
He obliged, shuffling closer on his knees. He dragged the thick, blunt head of his cock through her folds, gathering her wetness, mixing it with the oil. He massaged her with it, using the entire length to press and slide against her swollen clit, her aching entrance. It was not penetration, but a blatant, luxurious claiming of the territory.
“Christ,” she hissed, her hips lifting off the rug to meet the pressure.
“You wanted to explore the plateau,” Chris said, the words guttural. He positioned himself, pressing the broad tip against her. Even prepared, her body resisted the monstrous girth. He pushed, a steady, relentless invasion that made her breath catch.
She was tighter than Bea, different. A snug, muscular tunnel that fought him for every inch. He sank deeper, watched her mouth fall open in a silent O of overwhelmed pleasure. When he was fully seated, they both held still, prisoners of the overwhelming fullness.
“Fuck me,” she finally commanded, her academic crispness shattered. “Fuck me like you mean it, Christopher. Don’t hold back.”
He obeyed. He pulled out almost to the tip and slammed back in, a single, powerful stroke that drove a sharp cry from her lungs. He set a punishing, missionary rhythm, his body covering hers, the slap of their oiled skin a wet counter-rhythm to the fire's crackle. Each thrust was a deep, coring invasion that seemed to reach her very core.
“Yes! Right there!” she screamed, her nails digging into his shoulders. Her composure was gone, obliterated. Her legs wrapped around his waist, heels locking at the small of his back, pulling him deeper. “That’s it! Give me every bit of that monstrous cock!”
Her vocabulary dissolved into purely animal sounds—grunts, sobs, sharp inhalations. Chris felt a third climax, unimaginable after the others, building from his toes. He was a vessel for the candy, for her hunger, for his own crashing need to dominate this brilliant, unraveling woman.
“I’m going to come inside you,” he growled into the sweat-damp skin of her neck. “I’m going to flood that brilliant mind right out of you.”
“Do it,” she begged, her eyes wild. “Fill me. Mark your data. Now!”
The permission shattered him. His thrusts lost all rhythm, becoming frantic, deep jerks as he emptied himself into her with a hoarse, broken shout. She clenched around him, her own release a silent, breath-held convulsion that gripped him like a fist, milking him dry.
He collapsed, his weight settling onto her, his face buried in the fragrant crook of her neck. His cock, still half-hard and impossibly large, twitched inside her as the last of his seed spilled. The grandfather clock ticked loudly in the sudden quiet, measuring the breathless stillness they had created.
