A Slippery Revenge part 4

Natalie stirred in the dim haze of her bedroom, the air thick with a musky tang that clung to everything like a bad habit. Her eyes fluttered open to the sound of rhythmic moans echoing off the walls—low, guttural, laced with that familiar edge of desperation and thrill. She blinked, focusing on the writhing form across the room. Emily was suspended from the ceiling, her naked body slick and glistening, tentacles coiling around her limbs like living ropes. The appendages pulsed and squeezed, drawing out every drop of fluid from her, milking her pussy and ass with relentless precision. Emily's head lolled back, her mouth parted in a silent scream of ecstasy, breasts heaving as another wave hit her.

Natalie had grown used to this shitshow over the past weeks. The monster—Emily's fucked-up lab experiment gone rogue—had turned her apartment into a perpetual fuck-fest. What started as a prank with that test tube of slime-meat substance had escalated into this: a chaotic battleground where tentacles invaded every corner, binding and breeding them at will. Natalie remembered the tug-of-war they'd played against the things, laughing even as they yanked her helpless form. But now, as the ceiling above her creaked and shifted, she sighed and swung her legs off the bed. "Oh yes, it's time to return to normal," she muttered in a sleepy, calm voice, rubbing the crust of dried semen from her thighs. Nothing to be done about it. The cocoon-like enclosure they'd been trapped in for days had left them both raw, bodies adapted to the constant invasion.

Tentacles slithered down from the ceiling, parting like a curtain to make way for her. They wrapped around her shoulders first, cool and slick against her bare skin, lifting her effortlessly. Natalie didn't fight it; she arched her back as they gripped her arms, pinning them behind her head. More tendrils snaked around her heels, yanking her legs up and over, folding her into a bent position that made her spine crack audibly. "Yes, good," she gasped, a shiver of pleasure cutting through the ache. Her chest and stomach dangled freely now, nipples hardening in the cool air as gravity pulled at her. The position exposed everything—her shaved pussy lips parting slightly, ass cheeks spread wide. "It would be nice if you continued that with us. Since yesterday," she added, her voice tinged with excitement, remembering how Emily had laughed while Natalie vomited up a load of the monster's cum the night before.

"Good morning," Emily rasped from her spot on the ceiling, her own tentacles still pumping into her, making her hips buck. "How did you sleep after everything that happened last night?" Without warning, she hawked up a thick glob of semen—viscous and white, stuck in her throat from the night's relentless face-fucking—and spat it straight at Natalie's face. It splattered across her cheek, dripping down her chin and onto her tits, warm and sticky.

"You completely fucking nuts? You bitch, you monster!" Natalie screamed, twisting against her bonds as the tentacles held her firm, stock-still in the air. The spit burned with salt and something metallic, mixing with the dried flakes of sperm and milk already caked on her skin from their earlier torments. "I already have dried sperm and milk on my skin and you're adding more? Fuck, you can't get used to it. You're such a whore."

Emily chuckled, her body shuddering as a tentacle plunged deeper into her cunt, stretching her wide. "Well, you can't get used to it? Speak for yourself, slut. You've been begging for more since the thing first wrapped around your tits."

Natalie licked her lips instinctively, tasting the glob. She paused, eyes widening. "Wait a minute... is this Justin's sperm?"

Emily's grin faltered, surprise flashing across her flushed face. The tentacles around her slowed for a beat, as if the monster sensed the shift. "How the fuck do you know that?"

Natalie smirked despite her predicament, the memory bubbling up like a dirty secret. Back before Emily's lab fuckery turned their lives into this tentacle nightmare, she'd snuck around with Justin—Emily's boyfriend. "Well," Natalie drawled, her voice husky as a tendril teased her inner thigh, "we didn't just do it from below. I sucked him off proper, took every inch down my throat. It was nice. Tastes just like that—salty with a hint of whatever cheap beer he chugs."

"Oh yes," Emily moaned, but there was venom in it now, her hips grinding against the invading appendage. "And by the way, we did it every day. Then you ruined everything, you homewrecking cunt."

"Well, excuse me, friend," Natalie shot back, the tentacles tightening around her ankles, pulling her legs higher until her pussy was fully exposed, lips quivering. "In this race, the strongest wins. And by the way, how deep could you swallow his dick? I, for example, did it until the very end. Gagged but took it all."

Emily's eyes narrowed, even as pleasure twisted her features. A tentacle slipped into her mouth, muffling her for a second before she spat it out. "And yes, I did. But I, like no one else, know where to lick his balls and how to do a French kiss that'll make him cum in seconds."

Natalie laughed, the sound sharp and mocking, her body swaying in the air like a perverse hammock. "Yes? Why did I take him away from you so calmly then?"

"Because I've had a lot of work lately," Emily snarled, her voice breaking into a gasp as the tentacles squeezed her breasts, milking out beads of what looked like her own arousal mixed with the monster's fluids. "Instead of supporting me, you ended up taking my boyfriend away. Filming my encounters with that creature wasn't enough revenge—you had to steal my man too."

Natalie started yelling, her voice echoing off the walls as she thrashed, the bonds creaking but holding. "I just wanted to please him! He's a great guy, and you weren't satisfying him. All those lab hours, ignoring his needs."

"I can satisfy any person," Emily replied, defiance burning in her eyes. She walked—no, floated—slightly as her tentacles adjusted, carrying her closer to Natalie, their bodies inches apart in the suspended stock. "Even though I sit in the lab all the time, I have a lot of experience in this matter. Yes, I do."

Natalie met her gaze, the air between them crackling with old grudges and fresh heat. "Yes? Well, let's check. The first one who makes the monster cum will be able to prove she satisfies better." She grinned, nodding toward the pulsing mass above them. "Easily."

Emily grinned back, feral and challenging. "Yes, easily."

The argument hung in the air like a dare, their naked forms dangling from the ceiling stocks, bodies marked with the remnants of their shared torment—streaks of milk dried on Emily's thighs from when the tentacles had latched onto her like suckling infants, semen flaking off Natalie's ass from the gangbang-style pounding the night before. Natalie remembered the irony of it all: Emily, the scientist who'd unleashed this beast, now reveling in the chaos, laughing as Natalie retched up load after load. But guilt flickered too—Emily's creation had bound them in ways neither expected, turning pain into this twisted pleasure.

The monster seemed to sense the brewing dispute, its tentacles quivering with what felt like amusement. Slowly, it lowered them, the appendages uncoiling just enough to deposit their bodies onto the floor with a wet thud. Natalie hit the ground first, knees buckling as she scrambled to her feet, walking unsteadily toward Emily, who was released a second later. They faced each other, panting, skin flushed and sticky, pussies dripping from the morning milking.

Two new tentacles emerged from a crack in the floor, thick and veined, one resembling a massive cock—ridged and throbbing, easily a foot long with a bulbous head leaking precum. The other was a huge vessel, translucent and gaping like a cum-hungry mouth, positioned to catch whatever they could wring out. The rules were unspoken but clear: the one who filled it faster wins. Prove who was the better fuck.
