Strongest Incubus System

Aria pushed the door open with her hip, balancing three bags full of fresh ingredients. The smell of the market still lingered—warm bread, freshly picked herbs, ripe fruit. She was already thinking about the lunch she would prepare when something on the floor, right at the entrance to the room, made her raise an eyebrow.

A piece of clothing.

Specifically, Ester’s blouse.

”Hmmm?” Aria let out, a smile slowly appearing at the corner of her mouth.

One step further and another piece appeared. Demon’s pants.

Ah. Well. This was starting to get interesting.

She dropped the bags on the table with a soft thud, a laugh already escaping before she could even hold it back.

”Tsk, tsk... looks like someone had a very good time without me.”

Aria tucked her hair behind her ear, her mischievous gaze gleaming. Her feline tail—invisible to the naked eye, but very present to her—seemed to twitch with pure mischief. The curious instinct, natural and utterly impossible to control, had already taken over her steps.

And she loved it when the house was like this.

Disarranged in a... revealing way.

Like a kitten that had just found a forbidden ball of yarn, Aria began to follow the trail. The clothes formed a small path to the hallway. Ester’s light tunic folded hastily, Demon’s sash half-twisted as if someone had removed it with little patience—or no interest in patience.

”So careless...” she murmured, amused. ”Or so busy they forgot the world.”

Her feet silently touched the wooden floor of the hallway. The house was too quiet. There were no voices, no footsteps. Just a heavy, warm silence, the kind of silence that made her imagination boil.

Had that cold woman surrendered?

Were they fighting? Testing boundaries?

Or... ”training” in another way?

Aria covered her mouth with her fingertips, laughing softly. She loved to imagine. She loved to tease. She loved to discover.

And slowly, very slowly, she climbed the first step of the stairs.

Then the second.

The smell of the house had changed. A sweet perfume of residual magic lingered in the air, and she recognized it immediately: Ester. Her aura always left a subtle trail, like petals crushed between the pages of a book. Mixed with that was another smell—warm, dense—Demon.

Aria tilted her head, curious, her eyes sparkling.

”So you really lost track of everything, huh?”

With each step, the anticipation grew. She walked on tiptoe. Her movements were fluid, calculated, but charged with an excitement impossible to disguise.

When she reached the upper floor, she noticed another item on the floor: Demon’s gloves.

”Ah, those two... they definitely weren’t fighting.”

She crossed the hallway with the grace of a playful predator. Then she saw it.

A half-open door.

The door wasn’t just poorly closed; it was ajar, as if it had been pushed open hastily or left that way by sheer carelessness in the heat of the moment.

Aria smiled so wide it almost hurt.

”Oh... what a delightful scene I’ll find here?”

She approached slowly, leaning her back against the wall so that no creaking floorboards would betray her presence. Her fingers touched the edge of the door, but she didn’t open it—not yet. First she wanted to listen.

Her heart raced, fueled by pure adrenaline.

And, from behind the door, came a muffled sound.

Not exactly moans. Not exactly laughter. Something in between. A mixture of restrained voices, heavy breathing, perhaps even some whispered argument.

Aria bit her lip. ”What are you hiding from me, huh...?”

With the care of a professional thief, she leaned forward, her eye slowly approaching the crack.

But before looking, she stopped.

Why?

To savor the moment.

She loved this. This instant of absolute anticipation. This perfect point between what she imagined and what she would actually find. It was better than any surprise already prepared. It was the pleasure of almost.

Then, resting a hand on the doorknob, Aria inhaled slowly, letting her smile grow even wider.

Three... Two... One...

She pushed the door forward a few centimeters, enough to widen the crack without making a sound.

”But look...” she whispered to herself. ”Looks like I arrived at the perfect moment.”

She opened it a little more.

Enough to finally see.

Ester riding happily on Demon’s cock.

The fiery glow of their naked bodies was blinding.

Sweat and other fluids mingled, tracing the path of hands that caressed Ester’s hips and Demon’s tense back.

The sheets beneath them were a damp, crumpled mess, like the act itself: volatile, brutal, uncontrolled.

Aria swallowed hard, with a strange mixture of envy and excitement. Seeing Ester entangled like this with Demon was... intriguing. Wise men said that carnal acts of two kinds in harmony were pure lust, and here was the proof.

Suddenly, the most appetizing sight of all: Ester’s mouth squirting saliva and moans into Demon’s ear. Breathless, desperate, as if the deepest, widest crack wasn’t enough to extinguish her fire.

And the whole thing was beautiful in a sadistic way: such a perverse revelation of animal lust.

Aria leaned even closer, her eye practically glued to the crack. She couldn’t blink anymore. Her heart was pounding erratically. It was... it was an impressive sight.

Ester writhing forcefully against Demon, with an almost insane ferocity. Her ass bounced, her hoarse moans echoing through the room. Demon held her firmly by the hips, his hands pressing hard against her pale skin. His face was contorted with pleasure, his teeth clenched.

”Ah, fuck...” His voice was a guttural growl.

Aria couldn’t suppress a sigh of envy. His cock must have been buried deep in that ass... with Ester writhing like that, it was delicious torture.

Ester was completely lost. She clung to Demon’s shoulders, her nails digging into his skin. Her thighs tightened around his sides, as if trying to crush him entirely inside her. Uncontrolled moans escaped, each deeper thrust sending spasms through her body.

It was paradise. A private hell she never wanted to leave.

”You... are a monster,” she managed to hiss between thrusts.

”No...” Demon brought a hand to her neck, his voice faltering. ”It’s you who won’t stop...”

Aria smiled, too fascinated to look away from the crack in the window. It was what she had always imagined... two savages, literally fucking until the end of the world. Her body already burned with the sight.

Aria couldn’t contain herself. The scene was, by far, the most erotic she had ever seen. Ester and Demon were lost in a vortex of pleasure, completely out of their minds, forgetting everything in the world besides their intertwined bodies. It was impossible not to be aroused by this.

So, with a mischievous smile, she opened the door completely and entered the room. Ester and Demon didn’t even see her, so engrossed were they with each other. Aria leaned against the doorframe, one hand touching Demon’s exposed buttocks as she watched the two writhe in unison.

”Looks like the party started without me, huh?” she teased, laughing. ”What a shame... I love these games, and look, I’m your wife too, Demon.”

Ester and Demon were startled by the voice. Her body stopped instantly, panting. Demon, in turn, turned his gaze to Aria and frowned, unable to concentrate due to his arousal. He tried to push his hips forward, still deeply embedded in Ester’s buttocks, but she remained firm, motionless.

”What are you...” Ester swallowed hard, still panting. ”W-what are you doing?”

Aria approached the bed, caressing Demon’s body while he was still inside Ester. Demon reacted to the caress, moaning softly, his muscles tense with pleasure. His cock throbbed inside Ester, which made her moan loudly as well.

Aria leaned over Demon’s body, pressing her breasts against his back while kissing his neck. She slid a hand down his muscular stomach until she reached the hard cock that was still buried in Ester’s tight pussy.

Demonstrating skill, she grabbed it and began pumping up and down, provoking more moans from both of them.

”I want to play with you both too.” Aria teased in a husky voice. ”My body is burning for you both.”

Ester couldn’t take it anymore. Aria’s movements on Demon’s cock inside her were too much. With a loud moan, she came intensely, her inner walls tightening around his hard cock. Demon couldn’t hold back either and came, flooding her tight pussy with his hot sperm.

For a few moments, they stood still, panting and exhausted. But Aria wasn’t going to let them stop now. She pulled Demon’s sensitive cock out of Ester’s soaked pussy, then knelt down and began to lick the mingled honey of both. The taste of them together was sweet, and she couldn’t get enough.

”Delicious...” Aria murmured with a mischievous smile. ”But I’m not finished with you two yet.”

With a swift movement, she pulled Ester up and kissed her forcefully, thrusting her tongue into her mouth. Ester moaned in surprise as she tasted her own come mixed with Demon’s on Aria’s tongue. Then Aria stepped back and began kissing and sucking Ester’s sensitive nipples, teasing her until she began writhing in pleasure again.

Aria sat on Demon’s lap, rubbing her wet pussy against his growing erection. She sighed with pleasure as his hard cock slid between her vaginal lips. Then she began to move up and down, swaying her hips in a provocative rhythm. Demon groaned loudly as he felt her tight, wet pussy enveloping his cock.

Ester watched everything with an excited and hungry look.

Seeing Aria fucking Demon was too exciting a sight. She moved closer and began kissing and licking Aria’s neck as she swayed on Demon’s lap. Her hands explored the curves of Aria’s body, squeezing her round, soft ass.

Then, without warning, Aria pushed Ester down until she was on her knees in front of Demon’s throbbing cock. With a wicked smile, she made Ester wrap her lips around the swollen head of his cock.

”Suck it,” Aria ordered in a husky voice. ”Be a good wife.” Ester obeyed, sucking Demon’s cock as if it were a delicious ice cream. She did her best to swallow it all, taking it all the way down her throat several times. It throbbed in her mouth, swollen and hard as a rock.

Aria watched the show with a burning lustful gaze. Seeing Ester sucking her husband’s cock was the most erotic thing she had ever seen. Then she leaned forward, inserting two fingers into Ester’s soaked pussy while she sucked. The touch surprised Ester, but soon she began to writhe against Aria’s fingers, moaning around Demon’s cock.
