Possessed by boos

Lucia turned, expecting Maria’s usual glare—what she got instead was a leer. Maria’s eyes glowed violet, her lips parted around a tongue that unspooled too long, too wet, flicking against her own chin before retracting with a slurp. Lucia’s grip on the Poltergust faltered. "Oh, *fuck* no—"

Maria’s hands—no, the Boo’s hands—grabbed Lucia’s overall straps and yanked her forward. Their noses smashed together, teeth clacking, before Maria’s tongue **** its way into Lucia’s mouth. It tasted like ozone and spoiled candy, writhing deeper than any tongue had a right to. Lucia gagged, but her body betrayed her, hips stuttering forward into Maria’s as the Boo’s influence seeped into her nerves like ink in water.

Then Maria’s hands were under her shirt, calloused fingers skating up Lucia’s ribs, thumbs circling her nipples with mocking precision. Lucia’s back hit the wall, Poltergust clattering to the floor as Maria’s knee shoved between her thighs. "Mmph—Maria!" she managed, voice muffled by the tongue still fucking her mouth.

A giggle echoed from behind—Lucia’s head whipped sideways just in time to see another Boo phase through the wall, its grin splitting wide as it lunged. Cold flooded her veins, her vision swimming violet as the second ghost crammed itself into her skull like a fist into a glove. Her body arched off the wall, muscles no longer her own, a moan ripping from her throat as the Boo settled inside her.

Maria—no, her Boo—pulled back just enough to smirk, saliva webbing between their lips. "Sisterly love," the thing crooned in Maria’s voice, but pitched wrong, layered with whispers. Its hands made quick work of Lucia’s overall buckles, shucking the straps down her arms as the second Boo puppeted Lucia’s fingers to claw at Maria’s shirt buttons.

Lucia’s consciousness screamed, trapped behind her own eyelids as her body moved without her. Her fingers popped each button with agonizing slowness, pausing to trace the dip of Maria’s collarbone. The Boo wearing Maria shuddered, hips grinding forward as Lucia’s stolen hands shoved the fabric off her shoulders.

"Fuck," Lucia’s mouth said, voice dripping with ghostly glee, "always knew you wanted this." Her stolen hands groped Maria’s breasts, thumbs flicking over stiffened peaks as Maria’s Boo groaned.

Maria’s body pushed Lucia harder against the wall, one hand fumbling between them to wrench open Lucia’s pants. The Boo in control of Lucia’s limbs didn’t resist, instead tilting her hips up in invitation as Maria’s fingers slid under the waistband of her underwear.

Lucia’s consciousness recoiled—no no no—but her body arched into the touch, a wanton moan tearing from her throat as Maria’s fingers found her wet and throbbing. The Boo possessing Maria laughed, breath hot against Lucia’s neck. "Look at you," it purred, "all dripping for your sister."

Lucia’s stolen hands scrabbled at Maria’s belt, yanking it open with frantic urgency. The second Boo was curious now, drunk on the feedback loop of their stolen bodies—Lucia’s fingers wrapped around Maria’s cock (since when—? Oh, ghost magic, great), stroking roughly as Maria’s breath hitched.

"You—ah—you bastards," Lucia’s voice gritted out, fighting for control even as her hips rolled into Maria’s touch.

Maria’s Boo just grinned wider. "But you like bastards." It kissed her again, deep and filthy, as Lucia’s stolen hand guided Maria’s cock to her entrance.

Lucia’s consciousness howled—

The mansion doors burst open with a supernatural kick—Maria’s foot still raised mid-air, her overalls hanging off one shoulder, the other strap snapped. Lucia staggered beside her, pupils blown wide and violet, tongue lolling in a lazy mimicry of the Boo puppeting her limbs. Their synchronized moan curled into the haunted woods beyond, a sound too wet, too hungry to be human.

"Fresh meat," Maria’s voice purred, though the cadence was all wrong—slurred like a drunkard’s, layered with spectral echoes. Her fingers flexed, nails scraping Lucia’s hip possessively as they stumbled forward. The Poltergusts lay abandoned inside, their tubes still vibrating faintly with trapped ghostly energy.

Lucia’s head lolled toward the rustle of bushes. A twig snapped. A terrified Koopa crouched there, shell trembling as it eyed the sisters’ unnatural glow. "Ah," Lucia’s Boo crooned, her body twisting into a predatory crouch. "A starter." Maria lunged first—her knee pinned the Koopa’s shell to the dirt while Lucia’s fingers pried at its plastron, peeling it open like a fucking oyster. The Koopa shrieked, limbs flailing, but Maria’s stolen strength was relentless.

Lucia’s Boo guided her sister’s hand downward, past the Koopa’s frantically kicking legs—until Maria’s fingers brushed against slick, hidden flesh. The Koopa’s cries pitched higher, garbled by Lucia’s palm clamping over its mouth. "Shhh," Maria’s Boo whispered, thumb circling the creature’s clit with mocking gentleness. "We’ll make it good."

The Koopa’s resistance lasted three thrusts of Maria’s fingers—then its body arched, a strangled noise caught in its throat as the Boos pushed their influence into its veins. Its pupils dilated, violet bleeding into the whites of its eyes. "Yes," Lucia hissed, watching the Koopa’s limbs go slack, its tail twitching in helpless pleasure. Maria withdrew her fingers, glistening, and pressed them to Lucia’s lips.

Lucia’s tongue swirled around them, lapping at the Koopa’s juices with a groan—then froze. A new scent curled through the trees: sweat, gunpowder, the musky tang of a Hammer Bro’s armor. Maria’s head snapped up, nostrils flaring. "Bigger prey."

They abandoned the Koopa mid-orgasm, its body convulsing in the leaves as they stalked toward the sound of clanking metal. The Hammer Bro never saw them coming—Maria’s fist connected with the back of its helmet, sending it face-first into the dirt. Its hammer skidded out of reach as Lucia straddled its back, fingers digging under the rim of its armor. "Let’s see what you’re hiding," she cooed, heaving the breastplate aside.

The Bro’s chest heaved, its skin slick with battle-grime and panic. Maria’s knee nudged its thighs apart—then her teeth sank into its shoulder as she shoved two fingers into its tight hole. The Bro howled, muscles clenching, but Lucia’s hands were already wrenching its head back, her lips sealing over its in a kiss that **** its breath down its own throat.

Its struggles grew weaker, hips jerking erratically as the Boos’ corruption seeped in. By the time Maria’s cock (still glistening with the Koopa’s arousal) pushed inside, the Hammer Bro’s moans were begging.

Lucia watched, licking her lips, as her sister fucked their victim raw—until the Bro’s eyes rolled back, its body seizing in overstimulated ecstasy. Maria pulled out with a wet pop, cock twitching as the Bro’s climax splattered across its own armor.

Lucia’s hand wrapped around Maria’s wrist, tugging her toward the distant glow of Toad Town. "More," their voices chorused, harmonized by the ghosts beneath their skin.

The Boos laughed.
