M'gann's Steamy Alien Desires

The desert night hung thick and warm around the hidden canyon, where alien crystals pulsed with a soft violet glow against the sandstone walls. Danielle, twenty-eight years old, sat on the edge of the smooth stone platform she had morphed from the rock itself, her voluptuous green-skinned body catching the light. Most humans on Earth knew her as M'gann, the shy Martian who kept her true nature tucked away behind a pretty humanoid mask. Tonight she wore a simple wrap of living silk that clung to her heavy breasts and the generous curve of her hips, the fabric shifting with every breath.

Terrence, thirty, stretched out beside her, shirtless, his human skin flushed from the day's heat. He had been her willing lover for months in this secluded hideout far from any city, the place where shape-shifting Martians could drop the disguises they wore among humans. His dark hair stuck to his forehead. His eyes stayed on her, hungry and open.

Danielle's telepathy brushed the edges of his thoughts. She felt his hunger, the way he catalogued every swell of her green flesh, the dip of her waist, the thick thighs she had never quite learned to hide. Heat gathered between her legs. She had given him this familiar Martian-humanoid body again and again—the full ass, the heavy tits, the wet green cunt that gripped him so well—but never the rest. Never the flexible, semi-translucent true form that waited beneath her skin, the tentacles and tendrils she kept locked down out of shyness.

"You're staring," she said, her voice low.

"You're glowing," Terrence answered. His hand slid up her calf, rough palm against smooth alien skin. "The crystals do that to you. Makes me want to peel that wrap off with my teeth."

She laughed, a nervous sound that made her breasts jiggle. Her nipples tightened under the silk. For weeks her alien desires had been building—the need to unfurl completely, to let her true Martian anatomy take him, fill him, wrap him. She had been too shy. He was human. What if the slick emerald appendages, the extra limbs, the way her insides could grip and pulse and change shape, disgusted him?

Tonight the tension sat between them like a third body. His fingers traced higher, over her knee, toward the heat of her inner thigh. Danielle's breath caught. A faint shimmer ran across her green skin, the first hint of morphing she could not quite suppress.

"Terrence," she whispered. "There's more of me. The real me. I've been afraid to show you."

He sat up, close enough that she smelled his sweat and the desert dust on him. "M'gann. Danielle. I didn't come out here for the pretty green version you show the world. I came for you."

Her telepathy slipped, leaking a flash of image: emerald tendrils wrapping a hard cock, translucent flesh folding around a man's body, tentacles slick with her own arousal. She yanked it back, her cheeks darkening to a deeper green. Terrence's pupils blew wide. He had felt it.

"Do that again," he said, voice rough. "Show me what you want."

They moved closer to the cluster of glowing crystals, the violet light painting Terrence's chest and the ridges of Danielle's collarbones. She leaned in first, kissing him with a hunger she usually kept leashed. His mouth opened under hers. His tongue met hers and she let a little more of her true nature bleed through—her saliva slightly sweeter, her lips softening and then firming as she tasted him. His hands found her ass and squeezed, pulling her into his lap until the wrap rode up and her bare green cunt pressed against the hard line of his cock through his pants.

Danielle moaned into the kiss. Subtle tendrils, no thicker than fingers, sprouted from the small of her back and the insides of her thighs. They were slick, warm, a deeper emerald than her skin. One slid up Terrence's chest, circling a nipple, then another, teasing. Another pair snaked down, caressing the insides of his thighs, tracing the seam of his pants until he groaned and thrust up against her.

Her telepathy opened like a door. She poured images into his mind: her true body unfolding, semi-translucent, flexible as living water; tentacles coiling around his cock, pumping him, slipping into every hole he had; her cunt changing shape around him, milking him; the way she could hold him in the air and fuck him from every angle at once. She showed him the raw, tentacle-laced pleasure she craved, the nights she had touched herself in this canyon imagining him begging for more of her alien self.

Terrence broke the kiss, panting, his forehead against hers. "Fuck. Danielle. I want that. I want every inch of your true alien self. Don't hide it. Let it out. I want your tentacles on my cock, in my ass, wrapping my balls. I want you to stop pretending you're just a green woman with a tight pussy. Show me M'gann. The real one."

The words hit her like a command and a gift. Shyness cracked. She stood, pulling him up with her, and the living silk wrap dissolved into nothing. Her humanoid guise peeled away in a shimmer of heat and light. Green skin turned semi-translucent, glowing from within, her voluptuous shape remaining but becoming something more—fluid, exotic, Martian. Slick emerald appendages unfurled from her back, her hips, the base of her spine: tentacles of varying thickness, some delicate as tongues, others thick as a forearm, all gleaming with natural lubrication. Her breasts stayed heavy and full, nipples now faintly glowing. Between her legs her cunt remained, wetter than ever, but additional tendrils framed it, twitching with want.

Terrence stared, cock straining, and grinned like a man who had won the only prize that mattered. "You're so fucking beautiful. Come here."

Danielle's true form moved with a liquid grace that made the crystals seem dim. Two flexible tendrils, slick and warm, reached Terrence first while he still stood. One wrapped his cock the moment she freed it from his pants, coiling from base to head in a slow, pumping spiral, the inner surface of the tentacle ridged and pulsing. The second tendril was thinner, almost needle-fine at the tip. It kissed the slit of his cockhead, then pressed in, penetrating his urethra in a careful, slick slide that made his knees buckle and a broken sound tear out of his throat.

"Oh fuck—Danielle—that's inside my cock—"

She held him upright with other limbs, two sturdier tentacles bracing his hips, another around his chest. The urethral tendril worked deeper in tiny pulses, stroking the inside of his shaft while the thicker one squeezed and stroked the outside in opposite rhythm. Precome welled around the intrusion. Terrence's head fell back. Danielle's telepathy flooded him with her own arousal, the way stretching him that way made her cunt clench on nothing.

"You wanted every inch," she murmured, voice layered now, her true Martian resonance humming under the words. "You get it."

She lifted him then, gravity meaning nothing to her morphing limbs. Multiple tentacles wrapped his thighs, his waist, his shoulders, suspending him in the violet crystal-light a few feet off the stone. Danielle mounted him in the air, her translucent hips settling over his, her wet alien cunt swallowing his cock in one greedy drop even as the two tendrils stayed in place—one still coiled around the base and shaft, the other still buried in his slit, now trapped between her inner walls and his flesh. The dual sensation ripped a shout from him. She began to ride, hard, using her extra limbs to slam herself down while he thrust upward into the impossible tightness.

Inside her, she changed. Her cunt became a living sleeve of pulsating muscle, ridges and suction-cups blooming along the walls, massaging every inch of him in rolling waves timed to her bounces. The tendril in his cock throbbed in time. Danielle's heavy breasts bounced in his face, glowing nipples stiff. Terrence latched on, sucking one, then the other, groaning around the sensitive flesh as her milk-sweet alien taste hit his tongue. Each suck sent a jolt through her telepathic link, and she fed it back to him doubled.

A warm, thicker tendril, vibrating from some internal Martian frequency, slid down the cleft of his ass. It pressed against his hole, slick with her secretions, and pushed in. Terrence's whole body jerked in the air. The tendril found his prostate and began a steady, buzzing massage, circling, pressing, never stopping. Danielle rode him harder, her ass slapping against the tentacles that held his hips, her cunt squeezing in rippling contractions that milked his cock from root to the tendril-stuffed head.

Their minds locked. He felt what she felt: the stretch of her alien pussy around his human cock, the glow in her nipples as he sucked, the electric thrill of her own tendrils being used as tools of his pleasure. She felt his prostate lighting up, the burn and bliss of being filled front and back and inside his own shaft, the way his balls drew up tight against a coiling lesser tentacle that had begun to fondle them. Every thrust upward met her downward slam. Crystal-light flashed off her semi-translucent skin. Slick sounds filled the canyon—wet tentacles, wetter cunt, the obscene suck of her hole on his cock, the quieter filthy slide of the tendril working his ass.

"Take it," she gasped, riding him like she meant to break the air itself. "Take my true form. Your cock is mine. Your ass is mine. I'm going to pump you until you flood my alien cunt."

Terrence sucked harder on her glowing nipple, teeth grazing, and slammed up into her. The prostate tendril thickened slightly, vibrating faster. The one in his cock pulsed. Danielle's internal massage became a frenzy of sucking rings traveling his length. She wrapped two more tentacles around his torso, pinning him so he could only thrust and take. Her own orgasm gathered first in the telepathic loop, a green-white heat, and she dragged him with her, showing him the image of his come erupting into her, overflowing around the tentacles, dripping down onto the desert stone.

They broke together. Danielle's cunt clamped down in seizing, milking spasms, her whole translucent body shuddering, extra tendrils whipping and then locking tight around him. Terrence came with a raw shout, pumping jet after jet into her alien depths while the tendril in his cock felt every spurt from the inside and the one in his ass wrung his prostate until he had nothing left and still kept twitching. Come leaked around her seal, hot and human against her Martian flesh. She kept riding through it, internal pulses wringing him dry, her telepathy screaming their shared climax back and forth until the crystals themselves seemed to throb.

Danielle slowly gathered herself, the wildest extra limbs receding as she returned to her favorite curvy green humanoid shape, still voluptuous, still wrapped around Terrence in the air. A cocoon of warm, morphing tendrils held them floating under the desert stars, her cunt still stuffed with his spent cock, the last thin tendril lazily still nestled in his ass. She squeezed around him, a dirty leftover pulse, and let him feel through the link exactly how much of his load was still sloshing inside her Martian pussy.

She clenched again, grinding her wet green ass against the tentacles that cupped it, and whispered into his mind the only afterthought that mattered: next time she would stuff his throat with a cock-shaped tendril while she used the rest of him like a toy until he pissed come.

Her last remaining tendril gave his prostate one filthy parting throb and she hissed, "I'm going to keep your balls empty and your holes stretched, human, until you beg to sleep with my tentacles still buried in your ass and down your cock."
