Jen pushed open the bedroom door, her voice trailing off mid-sentence as the scene before her stole the air from her lungs. “Evan, I was thinking we could-” Her eyes widened as she cut off in shock, locking onto her boyfriend – shirtless and flushed – standing in the center of the room. Beside him, a creature of impossible beauty knelt, her crimson skin shimmering faintly in the dim light, horns curling back from her forehead like a crown of burning ivory. The succubus’s lips parted in a wicked grin, revealing small, glistening fangs, and her tail flicked lazily behind her, coiling possessively around Evan’s thigh.

“Well, well,” the demoness purred, her voice a sultry rasp that sent a shiver up Jen’s spine. “Looks this just turned into a threesome, big boy...” She rose to her feet in one fluid motion, hips swaying as she sauntered toward Jen, who stood frozen in the doorway. Evan stammered, “Jen, I- I didn’t mean” but the succubus cut him off with a throaty laugh, her amber eyes glinting with cruel delight.

“Oh, sweet boy, don’t lie to her now,” she teased, running a sharp-nailed finger down Evan’s chest as she stepped past him. “You summoned me because you couldn’t help yourself. Just like all the others. And now…” She stopped inches from Jen, her gaze raking over her like a predator sizing up prey. “Now I get to play with your little girlfriend, too!”

Before Jen could respond or attempt to flee, the succubus snapped her fingers lazily. A pulse of heat rippled through the air, and Jen’s world tilted violently. She felt herself falling, her body collapsing inward as the room grew monstrously large around her. Her scream finally came out, but as a pitiful squeak. The magic halted her fall before she landed, and then she was tumbling back up and toward the demoness, spinning through the air until she landed with a gasp in a slick, rubbery pit. The walls were translucent, stretchy, and curved, and the faint scent of latex hit her as she flailed in the shallow pool of liquid at the bottom. She pounded her tiny fists against the reservoir tip of the condom, her heart hammering as she realized where she was – and what was happening. Even with it still rolled up, the tip was deep and slippery enough that she couldn’t climb out at her new size.

Above her, the succubus’s voice boomed, dripping with mockery. “There we go, all snug and secure. Isn’t she adorable, Evan? I think so.” Jen looked up through the distorted lens of her prison and saw the demoness kneeling in front of Even and rolling the condom onto his cock with agonizing slowness, her fingers stroking him expertly as she worked. Evan’s face was a mask of guilt and arousal, his erection straining against the latex despite the horror in his eyes. Jen screamed his name, but her voice was too small, drowned out by the succubus’s gleeful cackle. He looked at her, but could probably only make out a dark little speck at most. Then he looked away again, guiltily.

“Here’s the game, lover boy,” the demoness said, dropping to her knees before him. Her tongue flicked out, tracing the air just shy of his tip as she gazed up at him with mock adoration. “You’ve got five minutes to resist me. If you can hold out, I’ll pop little Jen back to her boring old size, and you two can pretend this never happened. But if you cum…” She moaned lewdly, miming a dramatic orgasm, as her hand wrapped more firmly around his stiff cock. “She drowns in your mess, and then I shrink you down to join me for a very special finale.” She slid a finger between her thighs, smirking as she parted her drooling nether lips wider. Her face was perfect for seduction from below – wide eyes looking up into his, mouth open and tongue lolling out like an invitation to release into her throat…

Evan clenched his fists, his breath hitching as the succubus’s hand moved faster, her moans growing louder, more obscene. “Come on, Evan,” she taunted, her voice a velvet blade. “You summoned me because you wanted this. Don’t fight it. Let her feel you lose control. Show her you like me more…” Jen thrashed in the reservoir as the condom’s walls flexed slightly with every stroke, the liquid sloshing around her tiny form. She could see Evan’s jaw tighten, his eyes darting between her speck-like body and the demoness’s gorgeous, waiting lips. Then her view was blocked by titanic tits as the succubus giggled and leaned closer, her breath hot against Evan’s thighs and balls as she licked and nibbled in all the right places.

“Three minutes left,” the succubus sang, her tail curling up to tickle his inner thigh. “She’s so cute down there, isn’t she? Bet she’s begging you to save her. Or maybe…” She licked her lips, slowing her pace just enough to drag out the torment. “Maybe she’s jealous I’m getting all the fun. Or furious that you got her into this mess. Are you sure you want to let her grow back? I bet she’ll break up with you anyway…”

Jen’s screams of fear and rage had turned to sobs, her hands slipping against the slick walls as the succubus’s mocking laughter echoed around her. Evan groaned, his resolve crumbling under the demoness’s relentless assault, and Jen knew – deep in her sickened heart – that time was running out. So did the demon, who made a point to look right at the captive little woman as she seduced Evan, and winked at her playfully as if she wasn’t about to end Jen’s life for horny amusement.

Time was almost up. Evan’s breaths was coming in ragged gasps, his hands trembling at his sides as the succubus’s relentless teasing pushed him closer to the edge. Her amber eyes gleamed with sadistic glee, her hand pumping faster now, her tongue still out as if to catch the cum instead of the condom. “Thirty seconds, sweet boy,” she cooed, her voice a mocking lullaby. “You’re so close though – I can feel it. Don’t you want to let go? Mnnnhh… just cum for me, right here…” she moaned for him.

Inside the condom’s reservoir, Jen was treading in a mix of precum and lube now, her screams lost in the sloshing liquid as she felt the tension building outside her prison. “Evan, please!” she cried, but her voice was impossible to hear, drowned out by the succubus’s lewd moans. Evan’s face twisted in barely-resisted arousal, his body betraying him as his hips bucked involuntarily. “N-no, Jen, I’m-” His words choked off into a guttural groan, and then it was too late.

A hot rush of thick liquid flooded the reservoir, the torrent of cum crashing over Jen. She flailed, her tiny body overwhelmed as the thick, sticky torrent filled her prison, her mouth, her vision... The latex walls stretched taut around her but did not burst, trapping her in the suffocating deluge. Her last breath bubbled out as she sank with the dangling tip of the condom, the succubus’s delighted, triumphant laughter ringing in her ears.

Evan staggered back onto the edge of his bed, guilt and shame etched across his face as the demoness rose to her feet, still giggling. “Oh, you lost after all, huh?” she purred, her tail flicking with delight. With a deft flick of her fingers, she slipped the condom off and, as Evan watched, tied a knot in the top. If by some chance Jen had survived the flood, this action sealed her fate inside the bulging, translucent pouch. Not as much as what came next, though. The succubus held the condom up to her face, dangling between her fingers as she admired it like a trophy. “Look at that… you must not have liked her very much. Drowning is -such- a nasty way to die, I’ve heard. Such a naughty boy you are.” Then, before Evan could protest, she tilted her head back, opened her mouth wide, and dropped the entire mess – condom, cum, and Jen – onto her tongue. She snapped her head back and swallowed with an exaggerated gulp, a shiver of pleasure running through her as it slid down her throat. “Mmm, all mine now,” she sighed, licking her lips. Satisfied, as she claimed her sexual trophy.

Evan’s knees buckled, his voice a broken whisper. “Y-you monster…” But the succubus only smirked, stepping closer to tower over him. “Monster? Oh, darling, you haven’t seen anything yet.” She snapped her fingers again, and that same searing, magical heat enveloped Evan. He shrank in an instant, dwindling down to the size of an ant, his sky occupied entirely by a looming expanse of crimson skin and flawless curves. He barely had time to scream before her deft fingers scooped him up, dangling him before her at hip height with a wicked giggle.

“Time for your punishment, little sinner,” she teased, parting her thighs with a slow, sensual motion. Her pussy glistened, drooling with arousal as she brought him closer, her scent overwhelming his tiny senses. “You’ll live forever in here, my little toy. Or… well, you’ll die forever, but the experience will never end.” With a little more pressure from her slender fingers, she pressed him against her slick folds, her walls twitching eagerly as she pushed him inside her hungry cavern. Evan struggled uselessly, swallowed up by the hot, pulsing depths as she moaned, her body claiming him completely. The last thing he saw was the flicker of light vanishing beyond her distant pussy lips and withdrawing fingers.

Satisfied, the succubus stretched languidly, her tail swishing back and forth as a portal of flame yawned open behind her. “Back to hell we go,” she murmured, patting her belly where Jen rested and clenching her pelvic muscles around Evan’s eternal prison. With a final, mocking laugh, she stepped through the rift, vanishing into the inferno of her home – her two new playthings doomed to an eternity within her wicked embrace, albeit in very different ways.
