Modeus, The Lustful Demon// Helltaker Harem 2/10

Modeus’s white hair is a messy halo around her head, and glowing pink hearts literally float into existence around her horns as she stares up at you. Her red eyes are locked onto yours with a terrifying, wide-eyed intensity. Before you can even utter a greeting, she lunges forward, aggressively grabbing both of your hands in an absolute iron grip that completely betrays her fragile appearance.She leans in so close you can see the literal steam rising from her head. (She’s that horny for you.. 👀)

Her spade-tipped tail swishes violently behind her, knocking against the stone walls."You and me. Right now..? Sex~?" she blurts out, her voice a mix of a breathless whisper and a desperate, aggressive demand and a bit of a question.

Though, for this one time thing, you have two choices. There’s two dialogues, "M'lady, I'll take care of you”, or “DEVOUR BRAZIL 🇧🇷”.

You told her you wanted to hold hands. Modeus had never done it before. The concept alone was enough to make the floating red hearts around her horns spin faster. She had agreed, cheeks already pink, clearly bracing herself for something she thought was going to be the peak of perversion.

Instead of taking her hand, your fingers closed around the heavy soft weight of her left breast through the tight red top.

The reaction was instant.

Modeus’s eyes flew wide, glowing heart- shaped pupils blowing out as a full-body shudder ran through her. A sharp, broken sound left her throat—half gasp, half moan—and her back arched, pushing the massive soft mound harder into your palm. The fabric of her top strained as her breast overflowed your hand, the nipple already stiff and obvious under the material. Fresh hearts burst into existence around her head in a frantic cloud..

“I… I… is this what they refer to as… hand holding???” Her voice was high, and completely wrecked. “…how perverse~”

Another tremor hit her, stronger than the first. Her thighs pressed together hard, tail lashing behind her, and a sudden deep, involuntary clench rolled through her lower stomach. Heat flooded her core so fast it left her dizzy. She was ovulating—right now, from nothing more than the way you were groping her—and her body made no attempt to hide it. The scent of her arousal spiked, thick and sweet, while her free hand hovered uselessly in the air as if she couldn’t decide whether to stop you or pull you closer. She was still trying to process the idea that this counted as “holding hands,” even as her body had already raced far past it.❤️

The order on your phone said “Malina S.” You pulled up to the address, parked, and grabbed the insulated Hellepizza bag. Before your knuckles even touched the door it swung open.

Modeus stood there.

Short, pale, silvery-white hair full of cowlicks, two black horns, and a permanent cloud of tiny red hearts floating around her head. Her heart-shaped pupils were already blown wide. She was wearing a tight dark blazer over a red turtleneck that struggled to contain her massive chest, and an even tighter skirt that did nothing to hide the enormous, heavy curves of her ass and thighs.

She looked at the pizza bag, then at you, then back at the bag.

“You’re not… testing experimental love potions,” she said quickly, as if answering a question you hadn’t asked. “I mean—I’m not. Testing them. At all.”

You held out the receipt to get her signature. Instead she leaned heavily against the doorframe, thighs pressing together, tail flicking hard behind her. Her face went scarlet. The floating hearts multiplied.

“W-wait! Maybe… you and me can f-fuck!
I-I promise to tip extra!”

Her voice cracked on the last word. She was already breathing faster, clearly fighting the urge to just drag you inside by the shirt. The pizza was still in your hands. The door was still open. And Modeus was staring at you like the only tip she actually cared about had nothing to do with money.

You can either leave the horny devil, accept the offer, or maybe exchange phone numbers and later after work, y’all can fuck.

The last thing your systems registered before full activation was the sound of a door slamming and cardboard tearing.

Modeus had already dragged your shipping crate inside, locked the door, and ripped it open with zero patience. She was completely bare from the waist down—no pants, no panties—still dripping from the toy she had yanked out of herself the moment the doorbell rang. Her massive breasts strained against a tight red turtleneck as she hauled your chassis out of the foam packing and onto her bed like you weighed nothing.

She skimmed the manual in under a minute, eyes glowing brighter with every line she read. Mechanical morphing limbs. Adaptive lubrication. Direct neural feedback. Custom pleasure protocols. Exactly what the advertisement had promised.

She set her phone to record, propped it up on the nightstand, and sat beside you on the mattress. Floating red hearts multiplied around her horns. Her heart-shaped pupils were already blown wide.

“Hello. I Modeus, The Lustful Demon is recording a video in my bedroom to test the performance of my new expensive toy… for research.”
She pointed at you, voice already shaky with anticipation.
“Toy. Line. Now.” Your optical sensors focused. The recording light blinked red.

After saying your line and how you would help her “various tests” and help satisfy her high sexual needs, Modeus made a small, strangled noise of approval. Then she lost what little patience she had left. She yanked her turtleneck off in one motion, freeing her heavy breasts, and immediately grabbed the waistband of the simple pants your chassis had been shipped in. Fabric tore under her fingers. She didn’t even wait to finish undressing you properly—she was already climbing into your lap, thighs spreading, soaking wet and done waiting for the “test” to begin.

You were already ahead of schedule, like always.

The streets of Hell blurred past the windows as your cab hummed along, another early drop-off guaranteed. Then the rear passenger door opened and Modeus slid in.

Short, silver-white hair full of cowlicks, black horns, floating red hearts, and those glowing heart-shaped pupils. She was wearing a tight red turtleneck under a dark blazer and equally tight red pants that clung to every heavy curve of her hips and ass. The second the door shut she was already shifting in the seat, thighs pressed together, a faint but unmistakable scent of arousal filling the cabin.

You had barely pulled back into traffic when she leaned forward and tapped your shoulder.

“You and me, now?”

Her voice was breathless, eyes wide and shining. She squeezed her own massive breasts through the turtleneck like she couldn’t keep her hands still, tail curling tightly behind her. She had clearly watched one too many of those human “taxi driver” videos and decided this was the same thing. (As in she seen too much taxi porn videos and thinks that any taxi driver would pull a stop and fuck her in her mind.) In her mind the meter was already running for something other than distance. She was soaked, impatient, and completely convinced this was how the scenario was supposed to go.

Hell didn’t have public indecency laws. The sidewalks were full of demons who wouldn’t even blink. You could pull over right now, climb into the back, and give her exactly what she was begging for without a single consequence.

Modeus was still staring at you, hearts multiplying around her horns, waiting for the answer she already assumed she would get.
