eri’s playdate

Summary:When Nemuri accidentally double books her schedule, everyone wins. Nemuri gets a break. Her boyfriend gets a new toy. And Eri? Eri gets a lifelong addiction.

Work Text:Aizawa pulled up to Kayama's house, a modest two-story home in the suburbs. "Be good for Auntie Kayama, okay Eri?" 

Eri bounced on the balls of her feet, radiating excitement. "I will, Papa! Can I go see Auntie now?" 

With a heavy sigh, Aizawa grabbed the spare key from under the flower pot by the door. The house appeared dark and empty. "Straight to Auntie as soon as you're inside, understand?" 

"Okay, Papa!" Eri chirped, giggling at the way Aizawa's cheeks flushed every time she called him that. It was a small victory in their ongoing battle of wills, one that never ceased to amuse her.

Aizawa shook his head as Eri let herself in, waiting until she was inside before driving off to UA. He knew Kayama would keep Eri out of trouble. 

The house was quiet, dimly lit by the morning sun filtering through drawn curtains. Eri sniffed the air, catching a whiff of Kayama's perfume and something else--a masculine, musky scent. 

Eri crept down the hall, her socked feet silent on the wood floor. As she neared the bedroom, soft cries and grunts reached her ears. Her heart raced as she peered through the cracked door. 

Kayama was naked, bent over the edge of the bed as a large, muscular black man pounded into her from behind. The man's heavy balls slapped against Kayama's slick pussy with every thrust, her full breasts swaying beneath her. 

Eri's eyes widened, fixated on the thick, dark cock spearing into Kayama's pink flesh. Arousal coiled in Eri's belly as Kayama whimpered, clearly enjoying the rough treatment. 

The man growled, giving Kayama's ass a firm smack. "Gonna fill this slutty pussy up." 

"Oh god, yes!" Kayama cried. "Breed me, you beast!" 

Eri bit her lip to stifle a moan, heat flooding her small body. She slid a hand between her legs, rubbing at the ache building there as the man's thrusts grew erratic. 

With a roar, the man slammed deep into Kayama, clutching her hips hard enough to bruise as he pumped her full of cum. Kayama shuddered, mewling as her own orgasm overtook her. 

As Nemuri lay there, still panting from the intense orgasm, the man slowly pulled his massive, ebony cock out of her well-fucked pussy, inch by painstaking inch. Eri felt her own arousal spike at the sight, a warmth spreading through her body that she couldn't quite understand but couldn't resist either.

She must have made a sound, for the man turned and noticed her watching in the doorway. A slow, knowing grin spread across his lips. 

Eri froze as his molten gaze locked onto her, cock still dripping from Nemuri's ruined cunt. Her cheeks flushed bright red as she took in the sheer size and girth of him, desire stirring low in her belly. 

"Who do we have here?" he rumbled, his voice like velvet dipped in sin. "Such a pretty little thing. Certainly got yourself an eyeful, didn't you?"

Nemuri followed his line of sight. "Ah... Eri..." 

Nemuri panted, her eyes glazed with lust, her voice straining as she tried to maintain her composure. Her cheeks flushed a deep shade of crimson as she hastily attempted to cover herself with the tangled sheets beneath her. "Go back to the living room, sweetie."

But Eri couldn't tear herself away, her hand gripping the doorframe as her body began to respond to the sensual scene unfolding before her. The raw pleasure in Nemuri's eyes, it called out to something deep within her, awakening a hunger she never knew existed.

"Let the girl look," he rumbled. He turned his attention back to Eri, eyes dark with lust. "Like what you see, little one?" 

Eri whimpered, hands twisting in the fabric of her skirt. She nodded, unable to form words. Her panties were damp, slick arousal coating her inner thighs. 

"Get out, Eri," Nemuri pleaded, her breath coming in ragged gasps as she tried to maintain some semblance of dignity. "Go wait in the living room, and I'll come talk to you when we're done."

Eri shook her head, gaze fixated on the man's cock as if in a trance. She licked her lips unconsciously, wanting nothing more than to taste him. 

The man chuckled, a deep rumble that sent shivers down Eri's spine and seemed to vibrate through her very core. His gaze flickered over the girl's small form, taking in her flushed face and trembling hands with an appreciative glint in his dark eyes.

"Such innocence," he mused aloud as he walked towards Eri, his hips swaying ever so slightly to allow his impressive length to swing back and forth with each step.

Eri couldn't tear her eyes away from the man's approaching erection, her mouth watering as she took in every detail: the thick veins that pulsed beneath his dark skin, the glistening head that seemed to call out to her, begging for attention. She felt a strange mix of excitement and fear, unsure what would happen next but desperate to find out.

He reached down and grasped his cock, giving it a slow stroke. Eri bit her lip, whimpering, clenching her thighs together as she watched the man fist his cock, imagining what it would feel like inside her. She wanted him to ruin her just as he had Nemuri, to fill her with his seed until she overflowed. 

"Do you want to touch it?" the man asked, his voice low and seductive.

Eri could only nod, desire clouding her mind. Her hand inched higher, slipping under her skirt to rub at her soaked panties. Her eyes fluttered shut, losing herself to the building pleasure and anticipation. 

Nemuri shot her a scandalized look but did not protest further, a faint blush colouring her cheeks.

Eri startled as a large, warm hand gripped her wrist, pulling her hand from between her legs. Her eyes flew open and she gazed up at the man towering over her, his cock jutting out proudly. 

"No touching," he chided, a smirk playing at his lips. "You only cum when I say so." 

Eri whimpered, arousal and frustration warring within her. She nodded jerkily, submission overtaking any protest she may have voiced. 

The man hummed approvingly, reaching down to caress her cheek. "Good girl." 

With a sudden, swift motion, the man slapped his cock down onto Eri's face, causing her to gasp in shock. The heady scent of his pheromones filled her nostrils, sending a shiver of arousal down her spine and further igniting the fire that had begun to burn within her.

Eri's eyes widened as she unconsciously fell to her knees, her gaze never straying from the impressive member that now dominated her vision. Drool leaked down her cheek, her head tilting back instinctively to keep the man's throbbing erection as her sole focus.

"Good girl," he praised, his voice low and commanding. "Now, show me how much you want this."

Eri hesitated for a moment, her thoughts whirling frantically as she tried to make sense of the situation. It was wrong, wasn't it? To be so fascinated by a stranger's most intimate parts? And yet, as she looked up into the man's ebony eyes, she knew there was no turning back.

Slowly, tentatively, she reached out her hand, fingers quivering, her small hands hovering uncertainly above the man's throbbing cock. Taking a deep breath, she finally reached out and tried to wrap both her hands around the entirety of the man's girth, only to find that it was simply too thick for her fingers to fully encircle.

A shudder ran through her as she felt the heat radiating from his flesh, the power that seemed to emanate from him. Her body seemed to respond instinctively, her breathing growing faster and shallower as her grip tightened.

"Wow," Eri whispered in awe, her cheeks flushed with excitement as she marveled at the sheer size of the man's erection. "It's so... big."

"Good girl," the man murmured approvingly, a hint of a smile playing at the corners of his lips. "You're a natural at this, aren't you? Just remember to take it slow... savor every moment."

As Eri continued to explore the man's length, her heart pounding in her chest and her thoughts consumed by the overwhelming sensations flooding through her, she knew that she had crossed a line from which there was no return. And yet, as the first taste of pleasure began to bloom within her, she found she didn't care.

"Please, teach me how to please you," she whispered, her ruby red eyes locked onto his dark, predatory gaze.

"Very well," the man said, his tone laced with both approval and desire. "Begin by worshipping it with your tongue."

Eri gulped, suddenly feeling the weight of the situation. She had never done anything like this before, but something about the man's commanding presence spurred her on. Tentatively, she extended her tongue and gave the head of his cock a gentle lick. To her surprise, it didn't taste like chocolate, as she had naively expected, but rather a potent mix of thick, salty cum and Nemuri's sour love juices.

"Again," the man urged, watching intently as Eri complied, her tongue tracing slow, sensuous circles around the tip of his cock. The taste was unlike anything she had ever experienced before – raw, primal, and utterly addictive. With each lick, she felt herself growing more and more eager to please, her inhibitions fading away beneath the intoxicating spell of the man's erotic scent.

"Good girl," the man praised, his voice low and seductive as he locked eyes with Eri. "You're learning fast. Now, let me see how well you can take care of me."

As Eri continued to worship the man's cock with her tongue, she couldn't help but feel a sense of pride swelling within her. She had always been a quick learner, and the thought of using her newfound skills to satisfy the man before her filled her with a strange sense of purpose. It was as if she had been waiting her whole life for this moment, the opportunity to fully submit and to lose herself in the process.

"Please," Eri murmured between licks, her eyes shimmering with a mix of lust and innocence as she gazed up at the man. "I want to make you feel good."

"Very well," he replied, his fingers threading through her silvery-white hair as he guided her mouth closer to his cock. "Show me just how much you want it."

Feeling emboldened by his words, Eri leaned in closer, tracing the contours of the man's urethra with her pink tongue. She could feel the heat radiating from within, and the sensation sent shivers down her spine. Tentatively, she began to alternate between soft licks, tender kisses, and the occasional light nibble, her newfound addiction driving her forward.

"Such an eager little girl," he praised, reaching down to gently pat her head. The affectionate gesture stirred something deep within Eri – a desire to please, to submit, and to be rewarded for her actions.

"Am I... doing well?" she asked hesitantly, her breath hot against his skin.

"Very well indeed," the man replied, his voice husky with arousal. "You're a natural."

Eri's cheeks flushed with pride, and she felt a renewed sense of determination to fully satisfy the man before her. As she resumed her oral ministrations, she thought to herself, 'I'll make him feel so good that he won't ever forget me.'

With each lap of her tongue and delicate press of her lips, Eri became more adept at navigating the man's massive cock, her mind becoming increasingly consumed by the task at hand. An intoxicating blend of pleasure and submission coursed through her veins, fueling her every action.

"Open your mouth, my little treat," he commanded, his dark eyes locked onto hers.

Eri obeyed without hesitation, parting her lips. The man slid two thick fingers into her mouth and she sucked on them eagerly, imagining it was his cock sliding over her tongue instead. 

"Look at you," the man crooned. "So eager to please. I think you and I will get along just fine." 

He withdrew his fingers and Eri chased them for a moment before catching herself. She kept her mouth open, waiting for whatever the man chose to give her next. Her cunt pulsed in time with her racing heart, slick fluids coating her thighs. 

The man grasped her chin, tilting her head up. "Keep your mouth open. I'm going to fuck that pretty little mouth of yours, understand?" 

Eri shuddered, clenching her hands into fists to avoid touching herself. She nodded as best she could and the man grinned. 

"Good girl." 

He slid the head of his cock into her mouth and Eri's eyes fluttered shut, a muffled moan escaping her. Finally. She sucked on just the tip, tracing her tongue along the ridge and slit to taste the remnants of his and Nemuri's joining. Musky and salty, utterly intoxicating. 

The man hissed, his grip on her chin tightening. "Just like that, darling."

Eri smiled around his cock, happiness suffusing her. 

The man slid more of his length into Eri's mouth, groaning as her tongue continued its ministrations. "Fuck, such a good little cockslut. You love having this big, black cock in your mouth, don't you?" 

Eri moaned in agreement, relaxing her jaw to take him deeper. The stretch was almost too much, but she persevered, chasing the heady scent and taste of him. As he began to slowly press his cock into her throat, she felt her body lurch with pleasure, her senses overwhelmed by the intoxicating scent and taste of him. Her cunt clenched on nothing, soaking her thighs as more fluids leaked free. 

"That's it," the man crooned. "Take it all, I know you can do it." 

Eri swallowed around him as he slid deeper, her nose brushing against the coarse hairs at the base of his cock. Her ruby red eyes fluttered closed as she focused on accommodating his size, her jaw stretching wider than she ever thought possible. The sensation was intense, teetering between pleasure and discomfort, and Eri found herself craving more.

Feeling emboldened by the man's praise and her own growing arousal, Eri decided to test her limits. As his cock began to slide down her throat, she couldn't help but gag slightly, tears welling up in her eyes from the strain. But the moment he attempted to pull back, she threw herself forward, forcing his cock even deeper into her throat.

The man grasped her head in both hands, a snarl on his lips. "Such a perfect little cocksocket. This is where you belong, on your knees worshipping my cock with your greedy mouth." 

Eri moaned in response, the sound muffled by the thickness of his cock filling her mouth. Her thoughts swirled with a heady mixture of pride, submission, and an insatiable desire to please him.

'I... I want this,' she thought, her mind hazy with pleasure. 'I want to give myself fully to him, to be controlled, to be used for his pleasure.'

He drew back slowly only to slam home again, setting a brutal pace as he fucked Eri's mouth. She moaned and gagged, drool coating her chin and dripping to the floor below, but she didn't fight him. She took it, relaxing into the claiming of her mouth, of her body. She was his, to use however he wanted. 

Eri stared up at the man through teary eyes, watching his expression contort in pleasure as he used her mouth. His hands tightened in her hair, holding her in place so she couldn't pull away even if she wanted to. Not that she did. She wanted this, wanted to please him, to be filled and claimed and used by this man in any way he desired. 

He growled, hips stuttering. "Gonna cum down your throat, baby. Gonna fill your belly with my seed." 

Eri whimpered, cunt clenching. Yes, she wanted it. She wanted to taste his cum, to feel it sliding down her throat to pool in her belly. She sucked harder, relaxing her throat to take him as deep as possible. 

The man shouted, burying himself to the hilt in Eri's mouth as he came. Thick, hot ropes of cum flooded her throat, too much for her to swallow. It leaked from the corners of her mouth, dripping down her chin to land on her chest. 

He kept cumming, spurt after spurt of virile seed claiming her throat. Her belly felt heavy with it, stretched and full. Still, he remained lodged in her mouth, softening cock plugging her throat. 

Eri's vision blurred at the edges, her breaths coming in short, desperate gasps as her body struggled to find oxygen. The realization that she was on the verge of blacking out jolted her back to reality, forcing her to pull away from the man's massive cock.

"Pop!" Her lips released their tight grip with a lewd, wet sound that echoed through the room. Panting heavily, she glanced up at him through half-lidded eyes, her cheeks flushed and her lips swollen. She rubbed her hand between her thighs, feeling the slick heat building within her.

"Did... did I do well?" Eri asked, her voice timid and sweet, betraying her innocence despite the erotic sight before her.

"Very well, little one," he praised, a wicked grin spreading across his face. The words seemed to ignite something deep within Eri, and she felt her heart swell with pride and pleasure.

"Such a good little cocksocket," the man crooned, petting Eri's hair. "You took it all so well. But we're not done yet. I'm going to fill your cunt next, breed you full of my cum until your belly swells with my child." 

Eri whimpered, cunt clenching on emptiness. She wanted it, wanted him to claim her completely. To fill her and breed her like an animal in heat. She was his, to do with as he pleased, and she wouldn't have it any other way.

The man chuckled, tilting Eri's chin up with a single finger to meet her gaze. "On the bed. Present your cunt for me like a good little slut." 

Eri scrambled to obey, climbing onto the bed to position herself on hands and knees. She reached back with both hands to spread herself open, presenting her dripping pussy for the man's pleasure. Her hole fluttered, eager to be filled. 

"So wet," the man purred, settling himself behind Eri. He teased her opening with the head of his cock, rubbing it through her slick folds until Eri whimpered. "And so desperate for my cock. You're going to be a perfect little cumdump for me, aren't you?" 

"Yes," Eri gasped, rocking back to try and force him inside. "Please, I need your cock!" 

The man chuckled, giving her pert ass a sharp slap. "Patience, little one." Still, he obliged her plea, sliding home in one smooth thrust. 

Eri cried out, walls clenching down on the welcome intrusion. She was so full, stretched wide around his girth as he started to move. Hard, punishing thrusts that shoved her across the bed with each snap of his hips. 

It was perfect. Everything she'd dreamed of and more. Eri gave herself over to the pleasure, to the feeling of being so thoroughly used. She was his, she'd always been his, and she never wanted this feeling to end.

The man fisted a hand in Eri's hair, yanking her head back as he pounded into her. "Such a greedy little slut," he growled. "You love this, don't you? Love being stuffed full of my cock." 

Eri could only moan, lost in the haze of pleasure and pain. Her thighs were slick with her own juices and she rocked back to meet each thrust, desperate for more. 

"Please," she whimpered, though she wasn't sure what she was begging for. More, harder, everything he would give her. "Please, I need..." 

"I know exactly what you need." He pulled out abruptly, flipping Eri onto her back, ripping her panties and forcing her legs open wide. Then he was pressing inside again, even deeper than before in this new position. 

Eri screamed, back arching off the bed as he started to pound into her. The new angle allowed him to hit just the right spot inside, sending starbursts of ecstasy through her with every thrust. 

She was close, so close, heat coiling tight in her belly. Just a little more... 

The man bent over her, teeth closing around one pert nipple in a sharp bite of pain. That was all it took to send Eri tumbling over the edge with a wail, inner walls clamping down on the cock splitting her open. 

He growled, fucking her through the aftershocks of her orgasm until he followed. Hot cum flooded Eri's channel, filling her so full it leaked out around his softening cock. 

They stayed like that for a long moment, the man draped over Eri as she struggled to catch her breath. Eri sighed, utterly content and already craving more. She'd been made for this, to be his perfect little cumdump.

The man stared down at her with lust-glazed eyes, chest heaving. Then he smiled, reaching down to stroke Eri's hair in a possessive gesture. "You did perfect, little one. Daddy's so proud of you." 

Eri beamed, leaning into his touch. She lived to please him, to be the perfect cocksleeve for his pleasure. Knowing she'd succeeded made warmth bloom in her chest. 

"Thank you, Daddy," she said, voice hoarse from the abuse her throat had taken. She slid her fingers between her legs, rubbing at her swollen clit as she gazed adoringly up at the man who owned her, body and soul. She knew she would willingly submit to him again, eager to experience more of the intense pleasure that only he could provide.

Time passed in a hedonistic blur, each moment filled with pleasure. Eri learned more about her own desires than she ever thought possible, giving herself over completely to the powerful man and his skilled touch.

When the time came for Aizawa to return, when the door opened, he was met with a sight that left him momentarily speechless. Eri stood before him, her clothes askew and leggings torn. Thick globs of cum dripped down from between her legs, and ropes of semen decorated her smiling face like an erotic work of art.

"Aww... Is it time to go already?" Eri asked innocently, absentmindedly using a finger to scoop some of the creamy substance into her mouth.

Aizawa's cock twitched in his pants. Traitor.
