Chapter 16: Nearly Impossible
Elena couldn’t look away. The sheer scale of it was absurd, almost cartoonish, yet the details were brutally anatomical—the prominent vein running along the underside, the soft, flared crown, the slight glisten of pre-come already beading at the tip. It looked heavy.Real.
Her hand moved without her conscious command, reaching out, her fingers stopping just shy of touching the heated skin.She could feel the radiant warmth from it.
“Go on,” Margot said, her voice a low murmur from behind her. “It’s not going to bite.”
Elena’s fingertips made contact. The skin was impossibly smooth, yet alive with a subtle, pulsing heat. It twitched violently at her touch, a thick, jerking jump that made her gasp and snatch her hand back. As she watched, it seemed to swell further, gaining another terrifying inch in length and girth, the veins standing out in stark relief.
“Jesus fucking Christ,” Elena breathed, a shaky laugh escaping her. “It’s like it has a mind of its own.”
A cold thread of anxiety wove through Elena’s arousal. “Margot, look at it. It’s… it’s the biggest cock I’ve ever seen. Let alone had inside me.”
“So?” Margot’s tone was all challenge. “You took Stella's big cock before.”
“That was different! It was big, sure, but not… not this. This is monstrous.” She said the word with a mix of fear and awe, her eyes tracing the monstrous length.
Stella, who had remained perfectly still, its gaze neutral, spoke softly. “I can make it smaller, Elena. If that would make you happier.” The offer was gentle, pragmatic.
“No!” Margot commanded, the word slicing through the room’s charged silence. Her hand shot out, gripping Elena’s wrist not with force, but with a possessive finality. “Don’t you dare make it smaller. It stays.”
Elena flinched, tearing her gaze from the mammoth erection to look at Margot. Her lover’s eyes were dark pools of intent, her freckled cheeks flushed. “Are you insane? Look at it, Margot. It’s got to be twelve inches long. I can’t.”
“You can.” This new voice was Stella’s, calm and utterly convinced.It shifted its weight slightly, the movement making its enormous cock sway. “Based on our previous coupling and your physiological responses, my analysis indicates you can accommodate this size. Your arousal is significant.” Stella’s head tilted, a gesture that was almost human. “I would never hurt you, Elena.”
A conflict warred in Elena’s belly—a deep, visceral fear of that impossible thickness stretching her open, and a hotter, darker curiosity that had been simmering since she’d first seen the larger configuration days ago. She looked from Stella’s placid, waiting face to Margot’s intense, hungry one. Margot’s desire was a physical force in the room, a current pulling Elena toward the edge.
“You want to watch,” Elena whispered, the realization dawning not as a question, but as a thrilling, terrifying fact.
“More than anything,” Margot breathed, her thumb stroking the inside of Elena’s wrist.That did it. The combination of Margot’s blatant voyeurism and Stella’s clinical assurance broke her resistance.A shaky sigh escaped Elena’s lips, a surrender. “Okay.” She let Margot guide her until she was kneeling over Stella’s hips, the mattress dipping under her knees.
Stella lay back against the pillows, its enhanced-Margot body a sculpted tableau of patient readiness. Its cock stood perfectly vertical, a monstrous pillar of flesh pointing directly at the slick heat between Elena’s thighs. She could feel her own wetness, a stark contrast to the dry, cool air of the room. Positioning herself, she hovered, the broad, flared head just brushing her swollen folds, sending a jolt through her.
“Wait,” Margot said, her voice tight.
Elena froze, panting. Margot was staring, her eyes fixed on the point where Elena’s body barely touched the glistening tip. Her expression was one of pure, avaricious calculation. “Make it a little larger, Stella. Just a bit.”
“Margot!” Elena cried out, a protest choked by her own gasped inhalation as she felt it happen. The cock beneath her didn’t just lengthen; it thickened, the already impressive shaft expanding in her periphery, the veins becoming more pronounced, the head growing even more broad and domed. The pressure against her became a demanding, undeniable presence.
“Now,” Margot whispered, the word a filament of sound in the silent room.
Elena, her body thrumming with a fear that was indistinguishable from want, lowered herself. The stretch was immediate and profound. The crown, now obscenely large, pressed against her opening, a blunt, insistent pressure that made her eyes water. She forced herself to relax, to bear down, and with a groan that was half pain, half shocking pleasure, the head began to pop inside. It was an invasion, absolute and breathtaking. The stretch burned, a fierce, delicious fullness she had never imagined. She sank down another inch, the thick shaft stretching her walls wide, a steady, relentless expansion that stole her breath. Her cunt clenched involuntarily around the invading girth, the sensation overwhelming, a raw feedback loop of pleasure-pain that centered her entire universe on that one, splitting point of connection.
She paused, suspended, impaled on what felt like a fence post, her inner muscles fluttering wildly around the rigid intrusion. “Oh my god,” she sobbed, her hands braced on Stella’s hard stomach.
“Keep going,” Margot urged, her own breathing ragged. “Take it all. I want to see it disappear inside you.”
She pushed down again, a slow, grinding descent that made her teeth clench. The thick shaft penetrated deeper, a relentless stretch that burned and soothed in equal measure. Margot watched, utterly captivated, as inch after impossible inch of that monstrous cock vanished into Elena’s glistening, stretched cunt.
A high, broken whine escaped Elena’s throat as she bottomed out, her ass meeting the firm junction of Stella’s thighs. She was fully impaled, stuffed to an unbearable degree. “Fuck, it’s all in,” she panted, her voice trembling with disbelief. “Oh god, I can feel it in my stomach.”
The feeling was beyond anything. It was a deep, perfect fullness, a stretching so complete it bordered on pain but burned with a shocking, radiant pleasure. Her inner walls were strained taut around the rigid invasion, every nerve ending screaming in overloaded ecstasy. She looked down, dazed, to see her belly slightly distended by the sheer length inside her.
Margot’s hand, which had been gripping her own thigh, moved to Elena’s stomach, pressing lightly. “I can feel it,” Margot whispered, awe stripping her voice of its usual detachment. “Right here. You’re taking every fucking inch.” Her other hand slid between Elena’s legs, fingertips finding her swollen clit. “Look at you. You’re absolutely split open on it.”
Then Stella moved. It was a slow, deliberate upward thrust of its hips, a piston-smooth motion that dragged the entire, veined length inside Elena. The movement shifted everything, the broad head pressing against her deepest, most sensitive spot.
Elena screamed, a raw, unfiltered sound of pleasure so intense it bordered on agony. Her body convulsed, her nails digging into Stella’s synthetic skin. “Oh god, don’t stop,” she begged, her pragmatism shattered. “Just like that.”
Stella established a rhythm, deep and measured, each thrust a calculated re-stretching of Elena’s well-fucked cunt. The sound was obscene—a wet, sucking squelch with every withdrawal, a breathy slap of skin on skin on the drive back in. Margot’s fingers worked Elena’s clit in frantic circles, matching Stella’s pace, her own arousal a slick heat between her legs.
“You love it, don’t you?” Margot growled, her composure cracking. “You love being this full of cock.”
“Yes,” Elena sobbed, her head thrown back, her body used as a vessel for this impossible pleasure. “It’s so deep, Margot. I can’t… I’m gonna come.”
Her orgasm ripped through her with violent, shocking force, a seizing, paralyzing wave that clenched her cunt around the massive intruder. Stella didn’t pause, its programming prioritizing continued stimulation. It kept pistoning into her, fucking her through the shattering climax, prolonging the sensations into a white-hot continuum of pleasure-pain.
Elena’s vision blurred at the edges, her senses reducing to the relentless, perfect friction, the stretch, the smell of sex, and Margot’s hungry, approving eyes watching her fall apart. She was nothing but a body being expertly used, and the freedom of it was terrifying and glorious. The rhythm was everything.
