Chapter 11: First Penetration
Natalie’s reflection stared back, wide-eyed and breathless, her dark hair clinging to her damp temples. The cool air of the living room prickled her skin, a stark contrast to the furnace heat radiating from Molly’s body pressed flush against her back. Her own hand, trembling slightly, guided the impossibly thick, slick head of Molly’s cock against her entrance. The contact sent a jolt through both of them. Molly gasped, a sharp intake of breath that ruffled Natalie’s hair, her grip tightening reflexively on Natalie’s hips.
"Slow," Natalie breathed, the word barely audible over the frantic thudding of her own heart. Her body, however, betrayed her. Her hips tilted back instinctively, seeking pressure, seeking more. The thick crown pressed insistently against her slick folds, parting them, demanding entry. She felt herself yielding, stretching impossibly wide around just the tip. A low, involuntary groan escaped her lips as her inner muscles clenched and fluttered, trying to accommodate the sheer girth. The sensation was overwhelming – a burning stretch mixed with a deep, aching need. "Oh god, Molly…"
In the leaning mirror, their image was starkly intimate. Molly’s face, usually bright with sunshine, was etched with intense concentration and a flicker of panic. Her eyes darted between Natalie’s expression in the glass and the point where their bodies joined. Natalie’s own reflection showed flushed cheeks, parted lips, and eyes dark with a mix of apprehension and raw desire. She watched her own hand, knuckles white where it gripped Molly’s hipbone, anchoring herself. Her other hand remained at her core, fingertips slick, guiding, feeling the relentless pressure.
"Am I hurting you?" Molly’s voice was strained, tight with worry. She held herself rigid, barely breathing, terrified of causing pain. Her socked feet shifted slightly on the rug – the pink-and-white stripe and the purple star absurd anchors in the charged atmosphere. The scent of vanilla candles, usually comforting, felt thick and cloying now, mingling with the musk of their arousal.
"No," Natalie gasped, though the word was tight. "Not… not hurt. Just… full. Already." She pushed back again, minutely, encouraging. Another fraction of an inch slid inside. The stretch intensified, a deep, visceral burn that stole her breath. Her walls pulsed violently around the intrusion, a reflexive spasm that made Molly whimper. Natalie’s head fell back against Molly’s shoulder, her eyes squeezing shut against the mirror’s view for a moment, overwhelmed by the sheer physicality of it. "Don’t stop," she pleaded, her voice rough. "Just… slow. Like this."
Molly nodded jerkily, her chin bumping Natalie’s temple. She focused on Natalie’s hand guiding hers, on the minute rocking motion Natalie initiated. She pushed forward again, infinitesimally slow. Natalie felt the thick shaft inch deeper, the stretch radiating outwards, a profound pressure filling her core. Her fingers dug harder into Molly’s hip. "Fuck," she hissed, her body arching, trying to both escape and invite more. "It’s… huge. Feels…" Words failed her. It felt like being remade. The sheer impossibility of Molly’s delicate frame housing this thickness, now buried inside her, was dizzying.
"Tell me," Molly whispered, her breath hot on Natalie’s neck. Her own body trembled with the effort of holding back, with the intense friction surrounding her cock. "Tell me what it feels like."
Natalie forced her eyes open, meeting Molly’s gaze in the reflection. Her own eyes were glazed, pupils blown wide. "Like… like I’m splitting open," she admitted, a shaky laugh escaping her. "But… good. So fucking good, Mol. Like you’re everywhere." She rocked back again, taking another sliver of Molly inside. The stretch burned white-hot for a second, then subsided into a deep, throbbing ache of fullness. Her inner muscles fluttered again, trying to grip the impossible thickness. "Your turn," she breathed, her voice thick. "What… what does this feel like?" She gestured vaguely downwards with her chin.
Molly’s gaze dropped to where Natalie’s hand still rested, guiding her cock deeper. Her expression shifted, wonder mixing with the strain. "Hot," she murmured. "So tight. Like… like a fist." She swallowed. "Slick. And… god, Nat, you’re clenching." A shudder ran through her. "Feels… amazing. Terrifying." She pushed forward again, another fraction. Natalie gasped, her head tipping back further, exposing the long line of her throat. Molly pressed her lips there, a soft, desperate kiss against the frantic pulse.
Natalie’s hand on Molly’s hip slid around, fingers splaying across the small of Molly’s back, pulling her impossibly closer. "More," she demanded, the word ragged. "Now. Give me more." Her body was adjusting, the initial searing stretch softening into a demanding ache. She needed it deeper. She needed to feel Molly completely.
Molly hesitated for only a heartbeat, searching Natalie’s face in the mirror. Seeing the determination, the raw need eclipsing the pain, she obeyed. She pushed forward, a deliberate, steady pressure this time. Natalie cried out – a sharp, guttural sound that echoed in the quiet room – as another inch, maybe two, sank into her. The fullness was profound, breathtaking. She felt stretched to her absolute limit, yet the ache was morphing, transforming into something else. A deep, resonant thrum of pleasure began to pulse where their bodies joined, radiating outwards with each heartbeat.
"Look," Natalie gasped, her voice trembling. "Look at us." She forced her gaze back to the mirror. Molly’s reflection stared, transfixed, at the point of connection. Natalie’s entrance was stretched wide, glistening, enveloping the thick base of Molly’s cock. The sheer visual was obscene, intimate, and utterly captivating. Molly’s hand, still resting near Natalie’s hip, moved tentatively, fingers tracing the stretched skin where Natalie’s body met hers. The touch sent fresh sparks through Natalie’s overloaded nerves.
"See?" Natalie whispered, her hips beginning a tiny, involuntary grind against Molly’s thrust. "See how much I can take?" The challenge was laced with awe. The friction shifted, the slick drag sending jolts of unexpected pleasure chasing the ache. Her inner muscles clenched again, a powerful ripple that made Molly gasp and falter. "Don’t stop," Natalie urged, her voice gaining strength, her body actively seeking the rhythm now. "Move. Please, Molly. Move inside me."
Molly’s breath hitched. The fear in her eyes was rapidly being consumed by a dawning, fierce hunger. She pulled back slowly, the drag exquisite torture for Natalie, then pushed forward again, matching Natalie’s shallow grind. The movement was tentative, exploratory, but the sensation was undeniable. A deep groan tore from Natalie’s throat as Molly filled her again, the thick shaft rubbing against places that ignited pure, liquid fire. Her hand flew back, tangling in Molly’s hair, pulling her head down. Their lips met in a messy, desperate kiss, tasting salt and need.
Molly’s thrusts gained confidence, still shallow, still mindful of the impossible stretch, but finding a rhythm. Each inward stroke sent waves of intense sensation crashing through Natalie – the deep pressure, the friction, the sheer occupation of her body. Pleasure began to coil, tight and insistent, deep in her belly, intertwined with the lingering ache. She broke the kiss, panting, her forehead resting against Molly’s. "Harder," she rasped, her voice wrecked. "Just… a little harder."
Molly’s gaze locked onto hers in the mirror, a silent question. Natalie nodded fiercely, her hips pushing back to meet the next thrust. Molly obliged, driving deeper with a controlled force. Natalie cried out, her body arching, her fingers clawing at Molly’s back. The stretch flared hot again, but beneath it, the pleasure surged, undeniable now, a rising tide threatening to drown her. She watched their reflection – Molly’s focused intensity, her own ecstatic agony – as Molly’s cock pistoned into her, each stroke claiming more of her, forging a connection that was terrifyingly, exhilaratingly complete. The rhythm built, the sounds of their bodies meeting filling the vanilla-scented air, a primal counterpoint to the frantic beating of their hearts. Natalie’s world narrowed to the mirror, to Molly’s eyes, to the relentless, perfect pressure filling her utterly, driving her towards an edge she hadn’t known existed.
Natalie’s gasp ripped through the quiet room, sharp and involuntary, as Molly pushed deeper. Every nerve screamed, a symphony of stretching heat and profound pressure that threatened to buckle her knees. The thick shaft buried within her felt impossibly present, a defining anchor.
"Still okay?" Molly whispered, her voice tight, breath puffing against Natalie’s sweat-slicked neck. Her small hands, usually so expressive and light, gripped Natalie’s hips like fragile vices. The contrast was dizzying – that delicate, heart-shaped face, framed by messy blonde waves, etched with intense focus, driving that.
Natalie could only nod, grinding her teeth as a fresh wave of sensation crashed over her. "More talking," she managed, throat raw. "Less worrying." She forced a shaky grin, meeting Molly's worried eyes in the mirror. "Unless you're chickening out?" The old challenge, the easy banter from years of friendship, felt strangely grounding.
Molly huffed a surprised laugh, the tension in her shoulders easing a fraction. "Says the one clutching the table like it's a life raft." She shifted minutely, pulling back just a hair before sinking in again, smoother this time. The drag was exquisite, lighting sparks along Natalie’s spine. "God, Nat, you feel…"
"Like warm velvet wrapped around a pipe?" Natalie supplied breathlessly, the absurdity cutting through the intensity. Her own body shocked her. How could it accept this? How could it crave it? Yesterday, Nathan’s body knew nothing like this profound occupation.
Molly choked, a startled giggle escaping. "You’re impossible." Her next thrust was firmer, deeper, finding a rhythm Natalie’s body recognized before her mind. "Less pipe, more… furnace." She lowered her head, pressing a kiss to the curve where Natalie’s shoulder met her neck. "You’re burning me up."
The rhythm built, tentative at first, then gaining confidence. Short, shallow strokes became longer, deeper drives. Natalie’s reflection showed flushed skin, parted lips, eyes wide with disbelief and mounting need. She watched Molly’s small frame move against her, the powerful flex of her thighs belying her size, that substantial length disappearing again and again into Natalie’s yielding heat. The visual was obscene, undeniable, utterly captivating.
Each inward stroke sent shockwaves radiating outwards. The initial sharp stretch was fading, replaced by a relentless, building pressure that coiled deep in Natalie’s belly. A low moan vibrated in her chest, escaping on Molly’s next deep push. "There," Natalie gasped, her hand flying back to clutch Molly’s thigh. "Right there, Mol. Don’t stop."
Molly’s rhythm hitched, faltering for a second. "Fuck, Nat, you’re squeezing me like…" Her words dissolved into a groan as Natalie deliberately clenched around her. "Okay. Okay. Got it." She adjusted her angle, driving forward with renewed focus. Her thrusts became more purposeful, more insistent, hitting that spot inside Natalie with devastating precision. The ache transformed, blossoming into pure, liquid heat.
Natalie braced herself against the worn edge of the table, knuckles white. The deep, rhythmic pressure was unlocking something primal. Pleasure, thick and urgent, surged through her, eclipsing everything – the strangeness, the lingering echoes of Nathan, the sheer physical impossibility. It was just sensation, overwhelming and perfect. Her hips began to rock back, meeting Molly stroke for stroke, seeking more friction, more depth. "Faster," she demanded, her voice rough. "Please, Molly. I need…"
Molly responded instantly, her small body moving with surprising power, her pace accelerating. The force of it drove Natalie forward slightly with each thrust. The sounds filled the room – slick skin sliding, ragged breathing, the soft thud of bodies meeting. Natalie’s head dropped back against Molly’s shoulder, her eyes fluttering shut. The world dissolved into pure feeling: the drag, the fill, the relentless friction igniting a firestorm.
She felt Molly trembling against her back, heard the pitch of her breathing change, becoming higher, tighter. "Nat… I’m close…" Molly gasped, her rhythm starting to fracture. Her grip on Natalie’s hips turned bruising. "So close."
The confession shattered Natalie’s own control. The coil inside her snapped. Pleasure detonated, a white-hot explosion that tore through her core, radiating outwards in violent, pulsing waves. Her back arched violently as a guttural cry ripped from her throat, the sound raw and desperate. Her muscles clenched rhythmically, fiercely, around Molly’s thickness, trying to draw her impossibly deeper as the convulsions wracked her.
Molly cried out, a sharp, surprised sound, as Natalie’s fierce internal grip pulled her over the edge. Her hips stuttered, then drove deep one final time, holding Natalie impossibly tight as she came. Natalie felt the hot, insistent pulse deep inside her, the intimate flood triggering fresh spasms of her own. The sheer intimacy of it, the shared peak, sent a different kind of shock through her – profound and unsettling.
They stayed locked together, shuddering, breath sawing in ragged unison. Natalie slumped forward slightly, supported only by the table and Molly’s arms wrapped around her waist. The frantic energy drained away, leaving behind a deep, trembling exhaustion and a startling sense of… completion? Emptiness? She didn’t know. Molly rested her forehead between Natalie’s shoulder blades, her small body pressed flush, her softening cock still buried within Natalie’s trembling flesh. The silence stretched, thick with the scent of sex and vanilla, punctuated only by their slowing breaths. Natalie stared into the mirror, meeting her own wide, dazed eyes, the reflection showing the flushed aftermath, the physical evidence of what they’d just done. The woman who was Nathan just yesterday looked utterly transformed, utterly delighted.
The reflection in the leaning mirror held Natalie captive. Sweat cooled on her skin, contrasting sharply with the lingering internal warmth, the profound, almost shocking sense of fullness Molly had left behind. She traced her own flushed cheekbone, the curve of her jaw – Nathan’s angles softened, undeniably hers now – while a shiver traced her spine. That delight warred with disbelief; the sheer audacity of her body accepting, craving, Molly like that.
"Cold pizza?" Molly’s voice was a warm murmur against Natalie’s shoulder blade, her breath tickling. One hand rested lightly on Natalie’s hip, the other gesturing vaguely towards the coffee table where the half-eaten box sat. "Best recovery food. Scientific fact." She sounded utterly relaxed, her usual sunny demeanor already resurfacing, though her touch remained possessive.
Natalie finally managed to tear her gaze from the mirror, twisting slightly within the circle of Molly’s arms. The movement pulled at muscles deep inside her, a twinge that was equal parts ache and a reminder of the intense pleasure just past. She looked down at Molly, whose blonde hair was adorably tousled, cheeks still faintly pink. "Recovery?" Natalie managed, her voice rough. "Feels more like I just ran a marathon backwards. Naked. Uphill." She tried for wry, but it came out breathless.
Molly grinned, her eyes sparkling. "With style, babe. Serious style." She stretched, a full-body movement that pulled her away slightly, and Natalie felt a sudden, startling sense of loss coupled with a slick, intimate shift. Molly winced playfully. "Whoa. Okay. Still sensitive." She yawned, stretching her arms overhead. "Pizza. Now. Or I might faint from post-coital malnutrition. My dick demands carbs."
Natalie laughed, a surprised, genuine sound that felt good. It eased the strange tangle of emotions – the lingering physical shock, the dazed wonder, the sheer newness of it all. Yesterday, Nathan wouldn't have recognized this feeling, this deep, trembling satisfaction mixed with a vulnerability he'd rarely allowed. She cautiously stepped back, legs a little unsteady, the cool air hitting damp skin as they finally separated completely. The sensation was strange, a distinct pop followed by an emptiness that felt almost too vast. She reached out, bracing a hand on the back of the worn velvet armchair.
"See?" Molly winked, grabbing a floppy slice of cold pepperoni. "Wobbly legs. Classic symptom. Fuel required." She took a huge bite, cheese stretching, completely unselfconscious in her nakedness, the remarkable appendage between her legs soft now but undeniably present. She offered the box. "Seriously, Nat. Eat. You earned it."
Natalie’s stomach rumbled loudly in agreement, surprising her. The intensity had burned through everything. She took the proffered box, the cardboard cool against her fingers. The scent of tomato sauce and pepperoni cut through the heavier aromas of sex and vanilla wax. She picked up a slice, the grease congealing slightly at the edges. "Okay, okay," she conceded, her voice regaining some steadiness. "But only because your... uh... dick insists." She took a bite. It was lukewarm, slightly soggy, and tasted like the best thing she’d ever eaten.
"Told you," Molly mumbled around her own mouthful, plopping down cross-legged on the rug. She patted the spot beside her. "Floor’s more stable than your knees right now. Plus, better view of the ceiling." She tilted her head back, chewing thoughtfully. "We should get glow-in-the-dark stars. Make it fancy."
Perching carefully on the edge of the rug, Natalie focused on the pizza, the simple act grounding. The deep throb between her legs was a constant, pleasant hum now, a physical echo of what had happened. She watched Molly, the easy way she inhabited her space, her body, the impossible thing that was part of her. The fear, the initial disbelief, it was still there, a low thrum beneath the surface. But so was something else. Curiosity. A bizarre sense of rightness.
"Glow-in-the-dark stars?" Natalie echoed, wiping grease from her chin with the back of her hand. "Bit juvenile for porn star genitals, don't you think?" The absurdity of the statement, spoken so casually while utterly naked and sore on Molly’s rug, made a giggle bubble up.
Molly snorted, almost choking on her pizza. "Hey! My dick appreciates whimsy!" She gestured grandly with the crust. "It likes ambiance. Mood lighting. Maybe some smooth jazz next time." Her eyes met Natalie’s, bright and warm. "Seriously, though... you okay? Like, really okay?"
Natalie looked down at her half-eaten slice, then back at Molly. The concern was genuine, cutting through the levity. She thought of the mirror, the reflection, the impossible stretch and the shattering pleasure. The way Nathan's experiences felt like dimly remembered whiskey compared to this effervescent champagne. "Yeah," she said, the word softer now. "Stunned. Sore. Maybe a bit terrified." She offered a small, shaky smile. "But okay. Really okay. Just… processing the fact that I apparently really, really like impossibly huge dicks attached to my best friend."
Molly’s laugh filled the cozy room, rich and relieved. "Good processing!" She scooted closer, her knee bumping Natalie’s thigh. "And hey, for the record? Best friend’s dick likes you too. A lot." She nudged the pizza box. "Now eat. Big day tomorrow. Gotta keep your strength up." She waggled her eyebrows. "For… you know. Research purposes."
