Chapter 5: Experimental Protocol
The faint, medicinal smell of the bathroom still clung to her skin like a ghost, but Anya ignored it. She stood naked in the dim hallway, the only light spilling from the living room doorway, painting a long, slender silhouette on the worn carpet. The deep, resonant ache low in her gut was fading, replaced by a buzzing curiosity, a reckless energy born in the fluorescent glare beside the sink. The towel lay discarded just inside the bathroom.
Taking a slow breath that did little to steady her nerves but much to inflate her resolve, she walked into the chaos of the living room.
Belle was sprawled on the ancient, overstuffed sofa, her caramel skin gleaming under the low lamplight, one hand dramatically gesturing with a slice of cold pizza. Alexa perched on the floor nearby, cross-legged, stabbing the ketchup-stained napkin diagram with a pen, her fiery red hair a messy halo. The TV murmured some forgotten nature documentary, casting flickering blue shadows. The air hung thick with incense, stale pizza, and the familiar scent of shared lives.
They both looked up as Anya stopped just inside the doorway. The silence wasn't shocked, exactly. More… arrested. Belle’s pizza slice hovered mid-air, forgotten. Alexa’s pen froze mid-stab.
"Whoa," Belle breathed, her large, dark eyes sweeping slowly, appreciatively, down Anya’s tall, naked form – the curve of her C-cup breasts, the familiar slope of her hips, the long legs. Her gaze finally settled, inevitably, on the stark, neat scars low on her belly and the undeniable flatness beneath Anya’s small, flaccid cock. "Okay, Anya. Bold."
Alexa tilted her head, green eyes sharp and utterly clinical. "Bandages off. Good. Healing looks excellent. Minimal inflammation. How's the sensitivity? Any phantom limb sensations?" Her gaze, unlike Belle’s appreciative one, scanned the surgical site with detached interest. "The nerve mapping around the excision points is fascinating."
Anya met their stares, her grey eyes holding a strange mix of defiance and a vulnerability she usually buried deep. The cool air prickled her skin, raising goosebumps, but she refused to cover herself. The raw power of the orgasm she'd wrung from herself moments ago still thrummed low in her belly, a reckless confidence singing in her veins.
"Yeah, bandages are off," Anya stated, her voice steadier than she felt. She deliberately shifted her stance, letting the light fall fully on the altered landscape between her legs. "Sensitivity? Dunno about ghosts. But the rest of me?" She paused, letting the implication hang. "Seems… hyper-aware. Especially back there." A slight tilt of her hips emphasized the point.
Belle’s eyebrows shot up, a slow, knowing smile spreading across her face. "Oh? Did our little engineer do some post-op testing already?" She took a deliberate bite of pizza, eyes gleaming.
Alexa nodded, tapping her pen against her knee. "Self-stimulation is a valid data point. Verifying nerve function post-orchiectomy is crucial. Anal stimulation bypasses the removed gonadal nerve pathways entirely, activating the pelvic plexus directly. Fascinating feedback."
"Fascinating doesn't cover it," Anya said, a flicker of dark amusement in her eyes. "It was… apocalyptic. And he," she gestured dismissively to her small, untouched cock, "just… dribbled. Like a leaky faucet. Still useless." The words held the familiar self-deprecating edge, but beneath it was something else: a raw, newly discovered truth.
Belle set her pizza down, unfolding her voluptuous frame from the sofa with dancer's grace. She moved towards Anya, her large breasts swaying, her expression shifting from amusement to pure, sensual interest. "So… what's the plan, Petrova? More solo experimentation? Or…?" She trailed off, her meaning clear, her gaze dipping pointedly downward again.
Anya held her ground, the buzzing energy intensifying. The phantom weight of the padded cup she used to wear felt like a distant, absurd memory. "Sick of pretending," she declared, the words firm. "Sick of the fucking cup. Sick of hiding." She looked from Belle’s warm, inviting presence to Alexa’s sharp, curious gaze. "I need… I need to test it. For real. With… input. I need to know if that… that apocalypse… was a fluke. Right now."
Alexa was already scrambling up, scattering napkins. "Real-time comparative analysis? Excellent! Physiological response during partner interaction versus self-stimulation could yield significant data on psychosocial factors influencing perceived pleasure intensity." She was already unbuttoning her lab coat, revealing a lean torso and small breasts beneath a simple tank top, her own modestly sized cock visibly erect beneath her trousers – a state seemingly as natural to her as breathing. "Consent parameters?"
Belle was already shedding her tiny sequined top, unfastening her skirt. Her large cock sprang free, thick and heavy, already half-hard with anticipation. "Consent? Honey, she walked out here naked and demanded testing. I think that’s a signed waiver in triplicate." She winked at Anya, her movements fluid and confident. "Spitroast?"
Anya felt a jolt – part nerves, part pure, undeniable arousal flooding the hollow space where her fear used to be. The dark humor was a lifeline. "Yeah," she managed, her voice slightly rough. "Spitroast. Data requires… thorough methodology."
Alexa nodded decisively, kicking off her trousers and underwear. "Optimal positioning required. Belle, you take the front for cranial stimulation. I'll handle posterior access and monitor response metrics." She gestured towards the rug in front of the sofa. "Anya, supine position, please. Elevate your hips slightly for optimal alignment. Belle, support her head."
Belle laughed, a warm, rich sound. "Always with the positioning, Lexi." But she complied, grabbing a cushion and placing it on the rug. "Come on, gorgeous. Let’s get you calibrated." She held out a hand.
Anya took it, letting Belle guide her down onto the cushion. The rough texture of the rug against her back, the sight of her friends naked and ready above her, the lingering scent of incense and pizza – it was absurd, clinical, and intensely erotic. She hitched her hips up slightly as Alexa directed, feeling utterly exposed, the cool air swirling around her scars and her small, limp cock. The void felt vast, but the thrumming need was stronger.
Belle knelt at her head, her large, soft breasts brushing Anya’s shoulder, her large cock bobbing near Anya’s face. The familiar, musky scent of her filled Anya’s senses. "Open wide for the control variable, sweetie," Belle murmured, her voice a low purr as she guided the thick head of her cock towards Anya’s lips.
Anya obeyed, taking Belle in, the familiar weight and taste grounding her even as Alexa moved behind her. Cool fingers, precise and clinical, probed her anus. "Sphincter tone good," Alexa noted. "Lubrication minimal. Belle, pass me the petroleum jelly? It’s on the coffee table. Standard lab issue."
"Of course it is," Belle chuckled around her movements, reaching back without looking. She slapped the small tub into Alexa’s waiting hand.
Anya closed her eyes for a second, focusing on the solid presence of Belle filling her mouth, the rhythmic suction a familiar anchor. Then Alexa’s slicked fingers returned, circling her anus, much more deliberately than her own frantic exploration. The touch was cool, then warming, probing deeper with practiced ease. The jolt of sensation was immediate, sharpening the low thrum into a focused pulse. She moaned around Belle’s cock.
"Positive vocalization noted," Alexa stated calmly as one, then two fingers slid deep inside, curling slightly. "Internal musculature responsive. Engaging targeted stimulation."
Engaging was an understatement. The pressure, the angle – Alexa knew anatomy like she knew her own name. Anya’s back arched off the rug as the fingers found a spot that sent white-hot sparks shooting through her pelvis. Her thighs trembled. She sucked harder on Belle, a desperate counterpoint.
Alexa withdrew her fingers. Anya whimpered at the loss, the sound muffled by Belle. Then she felt the blunt, insistent pressure of Alexa’s smaller, rigid cock pressing against her entrance. Alexa’s hands gripped her hips, fingers finding the surgical scars for purchase. "Initial penetration commencing. Monitor for discomfort."
There was a moment of stretching, intense but not painful, then Alexa was sliding home in one smooth, deep stroke. "Full insertion achieved."
The sensation was overwhelming. Thick. Filling. Different from fingers, infinitely more present. It ignited the furnace in her core instantly. She was pinned between them – Belle’s cock stretching her mouth, Alexa’s cock spearing deep inside her, the surgical scars a strange anchor point for Alexa’s grip. The world narrowed to the relentless push-pull, the slick sounds, the mingled breaths.
Alexa began moving, slow, deep thrusts that dragged against that devastating internal spot with every withdrawal. "Rhythmic stimulation initiated. Observe physiological response."
Anya couldn't observe anything. Her eyes flew open, wide and unfocused. Pleasure, raw and tectonic, radiated outwards from her core with every thrust. It wasn’t just better than before; it was a different universe. Her body convulsed, her hands scrabbling at Belle’s thighs, her cries stifled by the cock in her mouth. Her own small penis twitched futilely against her belly, utterly ignored and irrelevant.
Belle moved with her, her thrusts gentle but firm, her hands stroking Anya’s hair. "That's it, gorgeous," she breathed. "Let it happen. Feel it all."
Alexa’s thrusts grew faster, more forceful, her scientist’s focus intense. "Increased tempo. Significant pelvic floor contractions. Pupillary dilation observed. Vocal intensity escalating." Her voice was detached, but her grip on Anya’s scars tightened, her own breath starting to hitch.
The pressure built, a coil winding impossibly tight. It felt like her spine was melting, like she was being unspooled from the inside. The sensations converged – the stretch of her mouth, the deep, ruthless friction inside her, the pressure on her scars – into one blinding point.
"Approaching critical threshold," Alexa gasped, her clinical tone finally fracturing.
Anya’s body locked. A sound tore from her throat, primal and unrestrained, vibrating around Belle’s cock. The orgasm detonated, a supernova in the void. It wrenched through her, wave after wave, obliterating thought, leaving only pure, shuddering sensation. Her vision whited out. Her limbs flailed weakly. She felt Alexa stiffen and shudder behind her, a sharp cry escaping her as she drove deep, her own climax triggered by Anya’s violent contractions.
As the blinding waves began to recede, leaving her trembling and gasping, she became aware of Belle groaning above her, her thrusts turning jerky before she stilled, pulsing hotly into Anya’s mouth.
Silence descended, broken only by ragged breathing. Alexa carefully withdrew. Belle slipped free. Anya collapsed back onto the rug, boneless, staring dazedly at the water-stained ceiling. Her body felt liquid, utterly sated. The familiar, pathetic twitch against her thigh was immediate. She glanced down. A few clear droplets beaded at the tip of her still-flaccid cock. A weak, postscript dribble.
Belle flopped down beside her, grinning. "Apocalypse, huh? Understatement. You practically levitated, Petrova."
Alexa crouched, peering intently at Anya’s face, then down at the negligible fluid on her belly. "Fascinating. Near-total disassociation of orgasmic response from the phallus. Subject experienced a high-intensity, full-body orgasm primarily centered on anal and pelvic nerve stimulation, with minimal secondary emission. Confirms my initial hypothesis regarding neural rerouting."
Anya started to laugh. It began as a shaky huff, then grew, bubbling up from deep within her still-quivering body – a raw, slightly hysterical sound of pure, dark amusement. She gestured weakly at the dampness on her stomach. "Told you. Useless." She looked at Alexa, then Belle, her grey eyes bright with exhaustion and a startling, newfound clarity. "But the rest? Fuck me." She grinned, the expression fierce and free. "Turns out I'm a bottom. A really, really aggressive bottom."
