On her birthday, my wife makes a wish that makes me turn into a gorgeous cock-hungry slut, and makes her grow a huge cock above her pussy. After the surprise passes, curiosity takes over.

Chapter 2: The Lace That Binds

The gasp ripped from Kelly’s throat, sharp and startled, as my palm pressed firmly against the hard ridge beneath her shorts. Her eyes flew wide, locking onto mine with a mixture of shock and pure, electric sensation. Then, it happened.

Her faded band tee shimmered. Like heat haze rising off asphalt. The worn cotton softened, blurred at the edges, dissolving into nothingness upwards from the hem. It happened faster than my own transformation – a silent, impossible vanishing act. One moment, worn fabric stretched over familiar curves, the next… bare skin bathed in the dim light. Her shoulders, the swell of her breasts, the smooth plane of her stomach – all exposed.

But not for long.

Darkness bloomed across her skin. Not shadows, but fabric. Intricate black lace, impossibly fine, materialized like ink spreading in water. It flowed upwards, weaving itself over her torso, lifting and cradling her breasts in cups of midnight lace. The scalloped edges traced the swells perfectly, sheer panels revealing dusky peaks that hardened instantly under the cool air and my stunned gaze. The lace continued down, swirling over her hips, coalescing into a matching wisp of black panties that clung low, sheer enough to hint at the dark curls beneath, yet framing the impossible reality straining against the thin cotton of her sleep shorts below.

Kelly stared down at herself, her hand still clamped over mine, pressing it against the bulge. Her breath came in shallow, ragged pulls. The black lace was a stark, seductive counterpoint to my own crimson. Wedding night lingerie, conjured from midnight air. Her gaze lifted slowly, meeting mine. The shock was still there, but beneath it, simmering hotter, was a fierce, primal fascination. And hunger.

"Felix…" Her voice was thick, rough-edged. Unfamiliar. "It… it feels…" She swallowed hard, her throat working. "More. Everything is… more." Her free hand drifted up, fingers brushing the intricate black lace covering her breast. A shudder ran through her. "The lace… it’s like… friction. Everywhere."

I understood. Oh god, did I understand. The crimson lace on my own body felt like a live wire, amplifying every shift, every breath. Seeing her in the black, feeling the hard heat jump against my palm beneath her shorts… it ignited something terrifyingly deep inside my new form. That hollow ache between my legs flared into a desperate, wet throb. My hips rocked forward instinctively, seeking pressure, friction, anything.

"Your shorts," I breathed, my voice trembling. "They’re… still there."

Kelly glanced down, a dazed frown appearing. As if realizing the incongruity for the first time. The thin cotton shorts were stretched obscenely tight over the distinct outline. "Right," she muttered, her voice rough. "Annoying." She shifted her weight, her hand leaving mine for a second to grip the waistband. She tugged. The fabric resisted, straining against the impossible bulk beneath. A frustrated growl rumbled in her chest – a sound utterly alien coming from her. "Stupid… thing… won’t…"

With a sharp, almost angry movement, she hooked her thumbs into the waistband and shoved downwards. The shorts slid over her hips, catching momentarily on the prominent ridge, then pooled around her ankles. She kicked them off impatiently.

Revealed.

It wasn't just an outline anymore. It was there. Thick, hard, and startlingly real, rising proudly from the dark curls at the base of her pelvis, just above the sheer black lace panties that dipped low beneath it. The shaft was flushed a deep, ruddy pink, the skin smooth and taut, veins tracing its length like cords under tension. The head was broad, slick with moisture at the tip, glistening faintly in the dim light. It stood rigid, angled slightly upwards, pulsing visibly with each beat of her heart. Or its own furious rhythm.

Kelly froze, staring down at it. Her hand hovered in the air, halfway back to mine. Her breath hitched audibly. The raw shock on her face mirrored my own internal scream. Seeing it was one thing. Seeing it like this, fully exposed, undeniably functional… it was visceral. Overwhelming. My gaze was locked, unable to look away from the sheer, impossible reality of my wife’s cock.

"It… it looks angry," she whispered, her voice thick with awe and a tremor of fear. Her hand slowly lowered, not towards me this time, but towards herself. Her fingers, trembling slightly, brushed the heated skin of the shaft near the base.

A guttural groan tore from her lips, deeper and rougher than before. Her head snapped back, eyes squeezing shut. Her hips jerked forward involuntarily, thrusting into her own tentative touch. "Oh… fuck," she gasped, her eyes flying open, wide and dark with stunned pleasure. "That… that’s…" She looked at me, her expression raw, vulnerable, desperate for understanding. "Felix… it’s… consuming."

The word resonated deep within my own transformed core. Consuming. That’s exactly what this new hunger felt like. A devouring void. Seeing her reaction, hearing that rough groan ripped from her throat… it amplified my own desperate ache tenfold. The wet heat between my legs intensified, a slick pulse that felt embarrassingly obvious. The crimson lace clung, damp now.

Her hand tightened around the base of her cock, her knuckles whitening. She gave an experimental stroke upwards. Her breath hissed out between clenched teeth. Her hips bucked again. "God… the pressure…" Her gaze, clouded with sensation, fixed on me. "Felix… touch it. Please. Touch me."

The plea shattered the last remnants of hesitation. Logic was ash. There was only the thrumming heat under my palm moments ago, the visual shock of its reality, and the answering, gnawing void within me. My hand lifted, trembling violently. My fingertips brushed the slick, heated tip.

Kelly cried out – a sharp, choked sound of pure sensation. Her cock jumped violently against my fingers. The skin was impossibly hot, silken smooth yet hard as steel beneath. A bead of moisture smeared onto my fingertip. The scent hit me then – musky, primal, utterly unfamiliar and intensely arousing.

I wrapped my fingers around the shaft, just below the head. The heat seared my palm. The solidity was shocking. It pulsed against my grip, a living, demanding thing. I squeezed gently.

Kelly gasped, her back arching. Her free hand flew out, gripping my shoulder for balance, her nails digging in slightly. "Yes… oh god, yes…" Her voice was a ragged whisper. Her hips began a slow, instinctive roll, thrusting gently into my encircling fingers. The movement was clumsy, unpracticed, but driven by pure biological imperative. "Like that… just… like that…"

The friction of her cock sliding in my grasp sent fresh jolts of that intense, alien arousal coursing through me. My own body responded violently. The ache between my legs became a sharp, insistent pang. Wetness soaked the crimson lace, making it cling coldly for a second before my own heat reclaimed it. My free hand flew to my hip, fingers digging into the lace, seeking pressure, friction, relief. A high whine escaped my lips.

Kelly’s eyes snapped to mine, dark pools reflecting the candlelight and raw need. Her thrusts became more urgent, her grip on my shoulder tightening. "You too," she rasped, her gaze dropping pointedly to the damp patch darkening the crimson lace between my thighs. "Show me. Touch… touch yourself."

The command, rough and desperate, unlocked something primal. My fingers, still gripping her cock, tightened instinctively as my other hand slid beneath the waistband of the crimson lace panties. The sensation was instantaneous, overwhelming. My fingertips brushed slick, swollen flesh – folds I didn’t know, nerves screaming with hypersensitive intensity. A cry tore from my throat, sharp and keening. My knees buckled. Only Kelly’s grip on my shoulder kept me upright.

"Felix," Kelly breathed, her voice thick with awe and shared desperation. She watched, transfixed, as my fingers explored the unfamiliar, drenched terrain beneath the lace. Every tentative stroke sent shockwaves through me, making my hips jerk, my breath catch in ragged gasps. The dual sensations – the hard, pulsing heat of her cock in one hand, the slick, aching sensitivity beneath my own fingers – created a feedback loop of pure, escalating need.

Kelly’s thrusts grew faster, harder. Her groans deepened, rougher, filling the vanilla-scented air. Her free hand left my shoulder, sliding down my side, over the curve of my hip, fingers tangling with mine where they worked beneath the crimson lace. Her touch was clumsy, seeking, but the added pressure, the shared exploration, was electric.

"Inside," she gasped suddenly, her voice strained, her thrusts becoming almost frantic. "Felix… I need… please…"

The raw need in her voice mirrored the yawning emptiness inside me. The void screamed to be filled. My fingers, slick with my own wetness, slid away from my aching flesh. Guided by instinct deeper than thought, trembling violently, I reached between her thrusting hips. My fingers found the source of her heat, slick and impossibly tight beneath the base of her cock. The entrance to her.

Kelly froze mid-thrust, a choked gasp escaping her. Her eyes locked onto mine, wide and startled. "Oh…" she breathed. "Oh… there…" Her hips pushed forward tentatively, meeting my probing fingers. The tight ring of muscle yielded slightly under the pressure. She groaned, deep and guttural, her cock pulting fiercely in my other hand. "Yes… there…"

My fingertip slipped inside. Hot. Tight. Clenching. Kelly cried out, her head thrown back, her body shuddering violently. Her grip on my hip tightened like a vise. Her cock jumped in my hand, thick veins standing out starkly. "More," she rasped, her voice shattered. "Please… more…"

I pushed another finger inside. The resistance was intense, but her body yielded, gripping me with shocking strength. She was impossibly wet, slick heat enveloping my fingers. Her groan was pure animal sound, raw and desperate. Her hips began to piston, fucking herself onto my fingers with frantic urgency. Her cock throbbed violently against my palm, slick with pre-come.

The sight, the feel, the sounds… it detonated inside me. The coil of tension in my own belly snapped. Pleasure, unlike anything I’d ever known – deeper, sharper, flooding every nerve ending – ripped through me. My vision whited out. My back arched violently. A scream tore from my throat, high and ragged, echoing Kelly’s guttural cries as her own hips slammed forward one final time, her body locking rigid.

Heat flooded my fingers inside her. Simultaneously, her cock pulsed violently in my other hand, thick ropes of white streaking across my stomach, hot and startling against my skin. Her cry mingled with my fading scream, a raw, shared crescendo that shattered the quiet bedroom.

Silence crashed down, thick and heavy, broken only by our ragged, gasping breaths. Kelly slumped forward, her forehead pressing against my shoulder, her body trembling violently. Her cock, still hard but softening slightly, rested heavily against my thigh, slick and cooling. My fingers, still buried inside her, felt the aftershocks pulsing through her clenched muscles.

Slowly, carefully, I withdrew my hand. It was slick, glistening. Kelly shuddered again at the loss. She lifted her head, her eyes meeting mine. They were dazed, unfocused, pupils blown wide. Sweat plastered dark strands of hair to her temples. Awe warred with utter exhaustion on her face. She looked down at the mess on my stomach, then at her own softening cock, then back at me.

"Holy shit," she breathed, her voice wrecked, rough as gravel. A shaky, disbelieving laugh escaped her. "Felix… did we just…?"

I couldn't speak. My body felt liquefied, every muscle trembling with residual shock and the echoes of that impossible climax. The scent of sex and sweat overpowered the vanilla candles. The crimson lace clung, damp and uncomfortable. The black lace on Kelly shimmered faintly with her rapid breaths. The reality of what we’d done, how we’d done it, slammed into me with the force of a physical blow. My wife. Her cock. My fingers inside her. Her come on my skin. My own body screaming with alien pleasure.

Kelly’s hand lifted, trembling, and touched the cooling streaks on my stomach. Her fingers came away glistening. She stared at them, then slowly, deliberately, brought them to her lips. Her tongue darted out, tasting. Her eyes closed for a second, a complex expression flickering across her face – surprise, curiosity, a dazed kind of satisfaction.

She opened her eyes, meeting my stunned gaze. A slow, utterly exhausted, but unmistakably triumphant smile curved her swollen lips. "Tastes… different," she murmured. Her gaze drifted down my body, taking in the crimson lace, the trembling curve of my waist, the damp patch between my thighs. Then back to her own softening cock resting against my leg. Her smile widened, turning wickedly playful despite the exhaustion. "Definitely need more data." Her fingers traced a lazy, possessive circle on my hip bone, just above the lace. "Lots more."

Exhaustion warred with the impossible hum still vibrating in my bones. "More data?" I rasped, my new voice sounding wrecked, alien. The evidence of our frantic exploration cooled stickily on my stomach, a stark contrast to the renewed, insistent throb between my own legs. My fingers, still resting lightly on Kelly’s hip where the black lace met skin, trembled.

She shifted, her softening cock a heavy, unfamiliar weight against my thigh. Her gaze, though hazy, was fixed with unnerving intensity on the damp crimson lace clinging to my hips. "Yeah," she breathed, her voice rougher than gravel. That playful, dangerous smile hadn't faded. "Thorough research protocol." Her hand, the one that had tasted her own spend just moments ago, slid from my hip, fingers trailing down my stomach.

They bypassed the cooling streaks entirely. Dipped lower. Brushed the soaked edge of my lingerie. A jolt like lightning shot through me, arching my back. "Kelly!"

"Shhh," she murmured, her breath warm against my shoulder. Her eyes met mine, dark pools reflecting the guttering candlelight and pure, predatory curiosity. "Just… sampling the environment." Her fingers hooked beneath the lace waistband. "Need a closer look." With deliberate slowness, she began to tug the crimson fabric down over my hips.

Air hit newly exposed skin, raising goosebumps. I was utterly bare to her now, sprawled on the rumpled sheets, every unfamiliar curve and contour illuminated in the dim glow. My heart hammered against my ribs. Kelly pushed herself up on one elbow, her gaze traveling down my body with a focus that was almost clinical, yet burned with undisguised heat. Her black lace shimmered as she moved, a stark silhouette against the warm tones of the room.

Her fingers returned, not tentative this time. They traced the outer curve of my thigh, then glided upwards, skimming the sensitive skin of my inner leg. My breath hitched, catching in my throat. Every nerve ending screamed. She paused, her thumb brushing the very edge of where the slick heat began. "So different," she whispered, more to herself than to me. "All… folds." A soft, wondering sound escaped her. "And wet. Jesus, Felix, you’re drenched."

Her touch drifted inward, a single fingertip tracing the swollen outer lips with agonizing lightness. I whimpered, my hips lifting off the mattress instinctively, seeking more pressure. "Kelly… please…"

"Hold on, scientist at work," she breathed, but her own breath was catching now. She lowered her head slightly, her dark hair falling forward like a curtain. The warmth of her breath washed over my most intimate, newly sensitive flesh. The scent of my own arousal, musky and deep, filled the small space between us. Another wave of slick heat pulsed out of me. Kelly inhaled sharply. "God, that smell…"

Her tongue touched me.

Just a single, hesitant stripe. Flat and warm. Starting low, near my entrance, and sliding slowly upwards.

My vision fractured. A broken cry tore from my throat. My hands flew to her hair, fingers tangling in the dark strands, not pushing her away, but holding on as the world dissolved into pure sensation. It was heat, wetness, pressure – focused and devastating. Utterly alien, yet somehow deeply, intrinsically right.

She did it again. Slower. More deliberate. The broad, flat surface of her tongue pressed firmly against me this time, exploring the shape, the texture. Lingering on the tight, hidden bud at the top. Applying gentle, maddening suction.

"Fuck!" The word was a gasp, a plea. My back arched violently. The sensations were overwhelming, too much, not enough – a whirlwind of nerve endings firing in chaotic, brilliant unison. Her fingers joined the exploration, spreading me gently, opening me further to her mouth and the soft, insistent pressure of her tongue. One finger circled my entrance, slick with my own wetness, pressing inward slightly but not penetrating. Just teasing the rim.

Her tongue focused relentlessly on that one hyper-sensitive spot. Circling. Flicking. Sucking softly.

Kelly’s tongue circled that impossibly sensitive spot again. Soft. Insistent. Maddening. My hips bucked uncontrollably against her mouth, a choked sob escaping me as the world narrowed to that single point of searing pressure. "Please… oh god, please…"

"Shhh," she hummed against my skin, the vibration radiating through my entire core like liquid fire. Her finger, slick and probing, finally pressed firmly against my entrance. "Just… exploring." It slid in. One knuckle. Slow. Deliberate. The stretch was sharp, intense, utterly alien, yet it ignited a deeper, ravenous hunger. "Tight," she murmured, withdrawing slightly only to push deeper. "So hot… and wet… Jesus."

The dual assault was annihilating. Her mouth relentless on my clit, her finger working deeper inside me, curling slightly. Sparks detonated behind my eyelids. My hands fisted in her hair, anchoring myself as my body bowed off the sheets. "Kelly! I can’t… ah!" Coherent thought dissolved. Every nerve screamed. The crimson lace felt like sandpaper against my hypersensitive skin.

"Feel that?" Her voice was thick, muffled against me. Her finger crooked again, pressing against a spot deep inside that sent a jolting shockwave straight to my core. My vision whited out momentarily. A guttural cry tore free, raw and desperate. "Yeah," she breathed, pulling back just enough to speak clearly, her eyes glittering with predatory fascination in the low light. "Found something interesting." She pressed that spot again, harder.

Pure electric agony-pleasure ripped through me. My body convulsed, arching violently. "Stop! Don’t stop! Please!" I was babbling, lost in the sensory overload. Wetness gushed around her finger, soaking her hand and the sheets beneath me.

Kelly chuckled, a low, rough sound that vibrated against my slick flesh. Her tongue returned, flicking hard and fast now, matching the rhythm of her finger. Out. Curling. "Gathering data," she gasped between strokes, her own breathing ragged. "Vital… research." Her free hand slid up my trembling thigh, fingers digging into my hip, holding me down as my body thrashed.

The pressure built, relentless, terrifying. A supernova gathering in my belly, radiating outwards. My cries became wordless gasps. The vanilla candle scent was obliterated by the raw musk of sex, of me. Kelly’s finger thrust faster, deeper, her tongue a furious pinpoint of fire. "Let it happen, Felix," she commanded, her voice thick with urgency and her own obvious arousal. "Come for me. Show me how this works."

It shattered me. No gentle wave, but a detonation. My body locked rigid, every muscle seizing. A silent scream ripped through my chest as pure, blinding ecstasy tore me apart. Pleasure crashed over me in brutal, shuddering waves, leaving me gasping, shuddering, utterly spent. Kelly’s finger remained inside, gently pulsing with the aftershocks, her mouth softening against me, lapping gently at the trembling flesh.

She finally lifted her head. Her chin glistened. Her eyes, dark and impossibly deep, met mine. A slow, utterly satisfied smile spread across her kiss-swollen lips. "Wow," she breathed, her voice wrecked but triumphant. "Data point: explosive." She slowly withdrew her finger, the loss making me whimper. She held it up, slick and shining in the candlelight, studying it with intense curiosity before bringing it to her lips, tasting deliberately. "Complex flavour profile," she giggled before laying down next to me. In her familiar embrace, we dozed off.
