Story: UY Side Effects

 

Lum's grip on Ataru's collar felt like a vice. She didn't just carry him; she hauled him through the air, her small frame possessing a strength that defied physics. The wind whipped against Ataru's face, stinging his eyes and stealing his breath. Every few seconds, a small spark of electricity danced across his skin, a playful reminder of who held the leash. The scent of ozone and something sweet, like crushed jasmine, clung to her.

"You naughty, naughty Darling," Lum cooed, her voice a melodic chime that sent a shiver of genuine terror down Ataru's spine. "Trying to run away from us? After such a wonderful night? I can't believe you'd be so cruel."

"Lum, please! Have mercy!" Ataru screamed, his legs dangling uselessly in the void. "I'm a fragile human! My heart can't take this much excitement! I need a nap! A long, several-year nap!"

Lum giggled, a sound that usually meant something was about to explode. She banked hard to the left, sending Ataru's stomach into his throat, and descended toward the Mendo estate. The sprawling mansion looked like a fortress of doom from this height.

As they touched down in the courtyard, the doors swung open with a theatrical bang. A welcoming committee waited.

Shinobu stood at the front, her usual timid expression replaced by a predatory hunger. Her cheeks were flushed a deep crimson, and her breathing was heavy, causing her chest to heave beneath her school blouse. Beside her, Ryoko leaned against a pillar, her eyes hooded and shimmering with a calculated lust. Ran was practically bouncing on the balls of her feet, and Ryuunosuke had her arms crossed, a smirk playing on her lips.

"He's back!" Ran squealed, lunging forward.

Ataru tried to scramble backward, but Lum dropped him unceremoniously onto the polished hardwood floor. He landed with a dull thud, the air leaving his lungs in a wheeze.

"Welcome home, Darling," Lum whispered, landing softly beside him. She leaned in, her breasts brushing against his arm, the warmth of her skin radiating through her thin clothing.

"I can't do this," Ataru groaned, staring up at the ceiling. "I really can't. You guys are too much. I'm just one boy! I have limits! Biological limits!"

Ryoko stepped forward, the click of her heels echoing in the silent hall. She looked down at him, her gaze sweeping over his trembling form.

"Limits are merely suggestions, Ataru," Ryoko said, her voice a smooth, authoritative purr. "Besides, we've discussed it. Your lack of stamina is simply a challenge we are all eager to overcome. We shall simply have to train you."

"Train me for what?" Ataru gasped.

"For the glory of the harem, of course," a new voice interrupted.

Ataru froze. He turned his head slowly to see Shutaro Mendo standing there. The wealthy heir, usually his bitterest rival, was wearing a crisp butler's waistcoat and a bow tie. He held a silver tray with a crystal carafe of a thick, milky liquid and several glasses.

"Mendo?" Ataru shrieked. "What the hell are you wearing? Why are you acting like a servant?"

Mendo stepped forward, his expression one of serene, brainwashed devotion. He bowed deeply, his forehead nearly touching the floor.

"My deepest apologies for the delay in your refreshments, Lord Ataru," Mendo declared, his voice devoid of its usual arrogance. "I have prepared a special concoction of maca root, ginseng, and several rare aphrodisiacs sourced from my family's private reserves. It is designed to maximize your endurance and ensure that your performance remains at its peak, even under the pressure of multiple partners."

Ataru stared at the drink, then at Mendo, then back at the girls.

"This is a nightmare," Ataru whimpered. "I've entered a parallel dimension where everything is backwards. Someone wake me up. Please, just hit me with a lightning bolt, Lum!"

"Oh, I'll give you plenty of shocks, Darling," Lum whispered, her hand sliding down to his thigh.

"Now then," Ryoko commanded, her voice snapping the others to attention. "We have a schedule to maintain. The brainwashing potpourri needs to be distributed to the other candidates, but first, we must ensure our God of Sex is properly... replenished."

Shinobu stepped closer, her hand trembling as she reached for the buttons of her blouse.

"I... I've never felt this way before," Shinobu murmured, her voice thick with desire. "I used to think you were a pig, Ataru. But now... I can't stop thinking about how much I want you inside me. It's like a fire in my stomach that won't go out."

"See?" Ran chimed in, sliding her arms around Ataru's neck from behind, pressing her soft chest into his back. "We're all in agreement! You're the best thing that ever happened to us! Now stop complaining and start working!"

Ryuunosuke grunted, stepping over and grabbing Ataru's ankle, pulling him toward the center of the room.

"Less talking, more fucking," she stated plainly.

The transition from the hall to the oversized master bedroom was a blur of soft carpets and grasping hands. Ataru was tossed onto a massive bed, the silk sheets cool against his skin, though the heat emanating from the girls quickly erased that sensation. 

Lum was the first to strip. She peeled away her tiger-striped bikini with a fluid motion, revealing breasts that were firm and topped with sensitive, coral-pink nipples. Her skin glowed with a faint, otherworldly luminescence. She crawled over him, her thighs rubbing against his hips, the scent of her arousal-musky and sweet-filling his nostrils.

"My turn first," Lum declared, her tongue darting out to lick Ataru's earlobe.

She descended upon him, her mouth capturing his in a wet, hungry kiss. Their tongues clashed and entwined, swapping saliva in a frantic exchange. Ataru felt the familiar spark of her electricity, but this time it didn't hurt; it acted like a stimulant, sending jolts of pleasure directly to his groin.

Shinobu didn't wait for an invitation. She stripped off her clothes with a frantic energy, her pale skin contrasting with the dark sheets. She knelt between Ataru's legs, her eyes wide and glazed.

"I want to taste you," Shinobu whispered.

She leaned down, her lips enveloping the head of his cock. Ataru let out a strangled cry as the warmth of her mouth clamped down. Shinobu was inexperienced, her technique clumsy, but the sheer desperation in her suction was overwhelming. She groaned into his skin, her tongue swirling around the rim of his glans, drawing out a bead of pre-cum that she swallowed with a loud, needy gulp.

"Oh, god," Ataru gasped, his hips bucking instinctively.

Ryoko had removed her clothes with a slow, deliberate grace. She stood at the edge of the bed, watching them, her hand sliding between her own legs. The sound of her fingers sliding through her own wetness-a wet, squelching noise-echoed in the room.

"Don't forget about me," Ryoko murmured.

She climbed onto the bed, positioning herself beside Lum. Lum shifted, moving her mouth from Ataru's ear to his chest, her tongue tracing the line of his pectoral muscles. Ryoko leaned over, her breasts hanging heavy and swaying above Ataru's face. He couldn't help himself; he reached up, grabbing one of her nipples and pulling it into his mouth. 

Ryoko let out a sharp, guttural moan, her back arching. "Yes... just like that, you wonderful animal."

The air in the room grew thick with the smell of sex-sweat, lubrication, and the heady scent of female arousal. Ran and Ryuunosuke joined the fray, their hands exploring every inch of Ataru's body. Ran's small, soft hands kneaded his thighs, while Ryuunosuke's rougher grip squeezed his glutes, her nails digging into his skin.

Lum decided she had waited long enough. She pushed Shinobu aside, though the other girl remained close, her face pressed against Ataru's hip. Lum lifted her hips, guiding Ataru's hardening cock toward her opening. 

She was soaking wet, her pussy glistening and open. As she lowered herself, the sound of the initial contact was a loud, wet squelch. Ataru felt the tight, hot grip of her walls as he slid inside her. Lum let out a long, trembling sigh, her eyes rolling back in her head.

"Darling... you're so big... you fill me up completely," she whimpered.

Lum began to move, her hips rotating in a slow, grinding circle. The friction was intense, the sound of their bodies colliding-a rhythmic slapping of skin against skin-filling the room. With every downward thrust, the air was pushed out of her orifice in a soft, wheezing sound.

"I can't... I can't take it!" Shinobu cried, her voice bordering on a sob. "Please, let me in too!"

The logistics of a harem were complicated, but Ryoko was a master of organization. She shifted Lum, guiding her to sit on Ataru's chest, while she herself maneuvered Shinobu. 

"Move over, Lum. Let the girl have her turn," Ryoko commanded.

Lum slid off with a loud, popping sound as the vacuum of her pussy released Ataru's cock. She didn't go far, instead beginning to suck on Ataru's nipples, her mouth creating a vacuum that made him hiss in pleasure.

Shinobu took her place. She lowered herself slowly, her face twisted in a mix of pain and ecstasy. Because she was tighter than Lum, the entry was slow. Ataru felt his cock stretch as he pushed past her entrance. A loud, shlicking sound accompanied the movement, the lubrication of her arousal making the slide smoother.

"Ah! It's... it's so much!" Shinobu screamed, her hands clutching Ataru's shoulders, her nails digging in.

As Ataru began to thrust, the rhythm grew more frantic. He was no longer the passive victim; the brainwashing had worked on the girls, but the raw, physical stimulation was working on him. He gripped Shinobu's hips, driving himself upward with a desperation he didn't know he possessed. 

The sound of their interaction became a symphony of wetness. Squelch, slap, shlick. Each thrust drove him deeper, his cock hitting her cervix with a dull thud that made Shinobu gasp and shudder.

"I'm going to... I'm going to cum!" Shinobu wailed, her internal muscles clamping down on him in violent spasms. 

She climaxed with a loud, shaking cry, her pussy milking him with an intensity that nearly brought him over the edge. As she collapsed against him, drenched in sweat and trembling, Ryoko stepped in.

Ryoko didn't waste time with modesty. She flipped herself over, presenting her backside to him. She arched her back, her rounded ass shaking slightly.

"I believe it's time for a change in perspective," Ryoko whispered over her shoulder.

Ataru didn't need to be told twice. He shifted, guiding his cock toward her tight, puckered asshole. He pushed forward, the resistance much greater than before. Ryoko let out a sharp, hissed breath, her fingers clutching the sheets.

"Harder," she commanded.

He lunged forward, the friction of her tight sphincter gripping him like a glove. The sound was different here-a tighter, more muffled squelch. He thrust deeply, the sensation of her tight walls surrounding him sending waves of pleasure through his spine. Ryoko's moans became guttural, her sophisticated facade completely shattered by the raw sensation of him stretching her open.

As he worked Ryoko, Ran crawled up beside him, her mouth finding his cock whenever it slipped slightly out of Ryoko's heat. She licked the shaft, cleaning the mixture of vaginal fluids and sweat with a devoted fervor.

The room was a chaos of limbs and fluids. Ataru felt like he was drowning in a sea of soft skin and loud, needy cries. Every time he thought he had reached his limit, another girl would touch him, kiss him, or whisper something vulgar in his ear that reignited the fire in his loins.

Eventually, the momentum reached a breaking point. Lum returned to the center, pushing the others aside to reclaim her spot. She sat on him once more, her pussy drenched and gaping from the previous rounds. 

"Now, Darling! Now!" she screamed.

Ataru felt the pressure building in his gut, a tidal wave of heat rushing toward his groin. He gripped Lum's waist, his knuckles white, and delivered three final, powerful thrusts. The sound of their pelvises slamming together was like a clap of thunder.

"I'm cumming!" he roared.

He erupted inside her, a massive, pulsing jet of semen shooting deep into her womb. Lum shrieked, her own climax hitting her at the same moment. Her internal walls gripped him in a rhythmic, crushing squeeze, milking every last drop from his cock. 

They stayed like that for several minutes, locked together, their breathing heavy and synchronized. Ataru felt completely hollowed out, his muscles turning to jelly.

As he lay there, staring at the ceiling, the girls began to cuddle around him, a tangle of naked bodies and damp skin. 

"That was... acceptable," Ryoko whispered, though she was smiling.

"I think I'm in love," Shinobu sighed, her head resting on Ataru's chest.

"We need to get more of that potpourri," Ran murmured, already drifting off to sleep. "I saw a few more girls at school who would look great in this bed."

Ataru closed his eyes. He could hear Mendo in the hallway, humming a tune as he likely polished the silver or prepared another stamina drink.

"I'm doomed," Ataru whispered to himself.

"Did you say something, Darling?" Lum asked, nipping at his chin.

"I love you," Ataru lied, because he knew it was the only way to get five minutes of peace.

Lum beamed, her electric aura flickering with happiness. 

"I knew you'd come around! Now, after a short ten-minute break, I think we should try that position from the book Ryoko found!"

Ataru's eyes snapped open in horror. The monkey's paw had not just curled; it had clamped shut around his very soul. He was the God of Sex, and his kingdom was a bedroom he could never leave.
