Chapter 13 - Shortstack Hero Ass (tatsumakiXizuku)

Izuku Midoriya has been assigned to the pro hero Tatsumaki, to learn what it means to be a hero. Will she prove too much for him to handle?

"Do try to keep up, won't you?" Tatsumaki demanded, glancing over a shoulder at her temporary sidekick – panting as he jogged after her. Deku had been following Miss Tatsumaki all day long, feeling admonished and ignored as she flitted from place to place without a care for his own capabilities. A few times he'd lost her, and had to check Hero Sighting Dot Com for her location – only to be tsked and derided when he eventually caught up. Maybe he would have managed better if not for his skin-tight hero suit: usually he felt free and agile in his costume, but under certain…conditions…it became impossible to move with speed. Since flight was Miss Tatsumaki's primary mode of transportation, that meant Deku was always looking up at her…right up her loosely-flapping, dark green dress. It was a big online joke that Miss Tatsumaki never wore panties, but Deku now knew the truth behind the joke. Her thick bubblebutt and slender, hairless pussy was always in his field of view, and no matter how he tried to ignore her feminine features, it proved impossible to keep his attention on the road. So he tripped, and tumbled, and provoked more of Tatsumaki's derisive sneers. "Of course they'd burden me with a useless newbie. What's wrong with you?"

"Guh…sorry," Deku murmured, pushing himself to his feet once again – and trying to disguise the bulge snaking down his leg. He gulped under Tatsumaki's emerald stare, all too aware of the way her dress hugged her lithe, yet ever so curvy body. He could see every contour of her tight belly and tiny tits, her bare thighs left sumptuously on display while the whole outfit flapped dangerously around her. Her deadly glare only enhanced her sexiness, and Deku knew his face was glowing dark red, his eyes wavering under the hero's stare. The silence was dragging on, so he added, "I guess I'm just…kinda clumsy today…"

"Is it because you're busy staring at my ass?"

"Whh—" Deku's eyes widened, his mouth dropping open as panic set in. "What do you—"

"Don't try to hide it." Tatsumaki descended, her high heels tapping lightly down on the sidewalk. She marched towards him and stood with her fists mounted on her hips, glowering up at him. "I'm the world's strongest esper; you really think I wouldn't notice? Of course they'd stick me with some pervert."

"I--…I--…" Deku gulped and wiped the quickly-forming sweatdrops from his forehead, his green eyes flitting everywhere but Tatsumaki's stare. "Uh…"

"God, you're timid." Tatsumaki crossed her arms and cocked her head to one side, poking her tongue into her cheek as she thought. "At least try not to burst before the end of the day. If it helps, think of my ass as a beacon. Follow it! If you trip one more time, I'll crush you."

With that, Tatsumaki kicked off the ground and hovered onwards, turning her attention back to her patrol. For a few seconds, Deku was left in her dust, breathing heavily, red-faced and dizzy…until he took off at a jog, crying out, "W-Wait for me!"

For the rest of the day, Deku burned with temptation and disappointment. Tatsumaki paid him no more attention; even when she stopped for lunch, she didn't buy him anything, but bought a burger and retreated to a nearby rooftop to eat. Hours passed, and Deku was starting to wonder if it was unhealthy to sport a raging boner throughout an entire work-day when, suddenly, Tatsumaki clicked her tongue. "Rooftop," she called, and vanished over the nearest roof.

It took Deku several minutes to find a way up to the roof. He could jump just fine, but not without incurring property damage, so he found a ladder and torturously climbed every rung – and when he finally arrived on the rooftop, Miss Tatsumaki was waiting for him, arms folded under her fabric-poking breasts, glaring at him like usual.

Deku checked his watch. "Oh… Patrol's over," he said. "Are you…going to assess my performance now?" He was out of breath, sweat glossing his forehead, obviously worked up from watching the most gorgeous ass he'd ever seen all day long.

Tatsumaki's eyes narrowed. "What performance? I noticed a fly buzzing behind me, but that's all. Kneel down."

Deku was so shocked by her insult that he didn't really process the second part of her sentence, but he found himself dropping to his knees all the same. Only a moment later did he realise what he'd just done. "Huh…?"

Before he could rise, Tatsumaki strode over to him and placed a hand on his forehead, holding him down. He shuddered under her soft, cool touch, peering up her torso, over the slight swells of her tits and into her cruel, dark green eyes. Tatsumaki observed him coldly for a moment…before a grin split her lips, showing her teeth. "Don't worry," she told him. "I've thought of a way you can be useful. If you're so addicted to my ass, you can at least worship it."

"Whh--?" Deku was completely unable to respond, too shocked by her words to conjure up an intelligent response. It was all just as well; for at that moment his vision was eclipsed by the thickest, softest pair of asscheeks he'd ever witnessed. Squish. They engulfed his features, spilling over and around his face in a wave of delicious softness. Suddenly, Deku was immersed in the scent of Tatsumaki's sweat; he could feel it soaking into his face, stinging his eyes… The overwhelming rush of sensations subdued him completely, and as he grasped her silky thighs in his hands, he inhaled deeply.

"I knew it," Tatsumaki said as she shuffled her hips from side to side, getting nice and comfortable on her new perch. "Just as I thought – you're a complete and utter whore. Look at you, about to burst through your pants with that oversized boner; you helpless slut." She started to pump her ass in slow circles over Deku's face, huffing and puffing as she ground her sensitive holes down on his features. Deku felt her slick, wet pussy against his chin…and her pucker against his lips. He groaned softly, then opened wide and stuck out his tongue, slithering around her winking asshole with slavish motions. Tatsumaki seemed surprised to feel his wet muscle against her; she covered her mouth with a hand and gasped, her eyes wavering slightly. "Oh…"

Deku squeezed Tatsumaki's plump thighs tighter. He just couldn't help himself; she tasted too good! He lapped his tongue rhythmically over her asshole, again and again, drawing sharper and heavier gasps from the petite woman's lips – until she started to squeak and moan in pleasure. Only then did he touch the tip of his tongue to her sweet little pucker…and plunge it inside without another moment's notice. He felt Tatsumaki's entire body tense as he started to lash at her insides, striking as deep as he could, making her toes curl and her hands bunch up into trembling fists. Her nipples stood up inside her dress, twin arrowheads that told the world just how horny she was getting. Slick cuntjuice poured down Deku's neck and chest as the lithe heroine squirmed above him, biting the crook of a finger in her distress, barely holding it together. Her slutty noises spurred him on; it seemed the great and mighty Tatsumaki wasn't as stoic as she believed.

"Nnrgh…not so fast," she snarled, but Deku kept going, pumping her hot depths with his agile tongue, refusing to give her even a moment's rest. Her eyes were starting to water, her lips pulling back from tightly-clenched teeth. She could get up at any time…but the pleasure from below was addictive, melting her thoughts into a steaming puddle. She was going crazy…

Deku squeezed Tatsumaki's asscheeks around his face, enjoying their loving press, determined to savour them as much as he could before his wet dream ended – but just as he plunged his tongue into her again, he heard Miss Tatsumaki cry out, felt her thighs clench as she pitched forward in absolute bliss. "Y-You--!" she hissed, and then she was cumming, squirting down his torso like a sloppy slut! Her pussy spasmed happily, even though it had barely been touched; bucking out a massive, girly orgasm just from the anal torment. Tatsumaki's expression was one of fury and bliss, green eyes tipped back in their sockets as she gurgled and pumped her wide hips, unable to contain her voice. "Ah! Ahhhn! Fffrggh… You little brat!"

Who knew Miss Tatsumaki's ass was so sensitive? Deku, dazed with pleasure, didn't want to let her go: he squished her thick asscheeks between his fingers, causing her plump, pale flesh to cascade through his digits as he mashed, mauled, and motorboated her colossal cheeks around his features. He closed his eyes tight and inhaled her sweat one more time…before lifting the shortstack and plunging his mouth over her pussy! Tatsumaki cried out as Deku started to feast on her sopping cunt, squeezing it inside his mouth and pressing his tongue across her needy slit like a red carpet. She shuddered and twitched, only able to mewl like a depraved little whore, lights of bliss flashing behind her eyes as Deku stroked her with that red-hot tongue of his. His powerful ass-groping didn't stop there either; he mashed her obscene cheeks in circles, appreciating them like they deserved to be appreciated, refusing to let go of the squirming fish on his hook. He ate her out like a marathon champion, finally plunging his tongue between her tight, clenching folds and sucking hungrily away, slurping up her juices like sweet ambrosia. Soon Miss Tatsumaki was panting, loud and depraved, her own tongue drooping from her open mouth as she tried to hold onto her mind. She clasped her face between her hands, whining and wheezing, her eyes going distant as the constant schlick, schlick, schlick of Deku's lips and tongue infested her mind. She was going to cum again, she just knew it – and nothing could stop it from happening. Even her greatest effort of self-control amounted to nothing when thrown against Deku's burning-hot lust. "Nnngh!" she cried out, withdrawing her tongue and biting her lip, shoulders spiking in her dress. She shuddered from head to toe, an emerald glow coalescing around her body – and in that moment, something odd happened. Suddenly, both hero and recruit were experiencing the same things – doubled up, like a sonic feedback of pleasure. Izuku could feel every jolt of bliss he sent up from her pussy and into her brain, while Tatsumaki could feel the painful throbbing of Deku's monstercock packed tight in his hero suit. She gave a long, shaky moan while Deku picked up the pace, slurping on her pussy like his life depended on it, drenching himself in the petite heroine's lewd juices while squeezing and plapping her asscheeks around his face. He was a total addict, he was--!

Tatsumaki wailed as she came – and in the same instant, so did Deku, their twinned orgasms resonating back and forth between their bodies. He bucked his hips and growled as he began to fire thick, churning streamers of jizz through his skintight suit – while Tatsumaki arched her back, giving extra definition to her taut torso inside her dress, and squirted once again. "Agghhnnn!" she cried, gasping for breath, one after another, her tiny titties heaving under the dark green fabric as she fought not to lose her mind!

The duo shuddered and spasmed there for a long time; even when they flopped apart, Tatsumaki toppling onto her face in a puddle of Deku's splooge and Deku collapsing onto his back, they continued to moan and wriggle. The occasional rope of cream continued to buck out of Deku's suit and over his twitching thighs, while Tatsumaki reached down between her spread thighs and stroked her clit hungrily. They were still connected, able to feel every sensation the other did, and the doubled-up pleasure was affecting their minds, making them gurgle happily.

"Nnnh…ah…" Tatsumaki picked herself up onto her knees and turned, looking over Deku with hungry eyes. She wet her lips while her hands opened and closed by her sides. Suddenly, she lunged, and Deku's shoulders were pinned to the ground – a petite, tight-bodied little esper straddling his hips. Her eyes were wild, angry. "Fuck me, now, or I'll break every bone in your body," she hissed.

Deku groaned. He'd just spurted a massive orgasm, and he was still rock-hard. Even if she hadn't demanded, he knew what he had to do. Reaching down, he clawed at his hero suit, pinching the material with the strength of One For All and tearing into it, stretching and ripping the high-tech fabric so his monstercock could fly free! It lurched up into the air and SMACKED Tatsumaki's ass like a baseball bat, drawing a sharp cry from her lips. She felt the same relief he did, the sensation of all that pressure releasing from around 'their' cock… She started to pump her hips up and down, wobbling and bouncing her gorgeous bubblebutt, twerking against Deku's heaving shaft while he gasped short, shuddering breaths. Seeing her mounted on top of him like this was more than any man could bear; taking hold of Tatsumaki's shoulders, he rose up and tried to kiss her, but she turned her head away.

"H-Hey!" she snapped. Her hips continued to buck and twerk rhythmically, even as she snarled at him. "Who said you could do that? I gave you an order, right? So get to it."

"Y-Yes, ma'am." His voice was a barely-coherent slur. "But only after…you give me an assjob I'll never forget…"

Tatsumaki's cheeks flushed red. "So that's what you want, is it?" she snapped. "Fine – but if you don't pleasure me properly afterwards, I'll—"

"Y-You want it too, right?" Deku panted. "You can feel what I feel." He traced two fingers down Tatsumaki's flat tummy, teasing them both with the tickling sensation. "Don't you wanna feel those fat, juicy asscheeks pumping around your cock?"

Tatsumaki bit her lip, but said nothing else; instead she wrapped her skinny arms around Deku's neck, lifted him into a sitting position, and squatted over his lap. "Mrrgh…" She started to BUCK her hips ferociously up and down, exerting herself to bounce her ass all over his cock. Deku grasped his hilt to hold his monster steady, so it dug under the shifting flap of Tatsumaki's dress and up into the valley of her sweating asscheeks. Soon her butt was pop, pop, clop-ing down on his pelvis with each pump, and they were both crying out in tender bliss, their open mouths inches from one another. Deku's fingers dug into Tatsumaki's back, while hers tugged pathetically at his hair; neither of them wanted this to end!

"So this is…what it's like…to lug a big slab of meat around in your pants?" Tatsumaki growled between clenched teeth. "I don't see…what the big deal is…"

Deku grunted – and brought an open palm down on Tatsumaki's asscheek. THWAP! They both cried out as pleasurable pain rippled through them. "That must be…why you're gushing so much…"

"Shut up," Tatsumaki said, and silenced him by shoving her chest over his face. Deku groaned against her for a moment, then opened wide and trapped one of her stiff nipples between his lips, sucking hungrily on her flat titty. Tatsumaki had never experienced such a thing in her life; she moaned out loud, resting her chin on Deku's scalp and shaking as his tongue lashed the tip of her sensitive bud. "Hnn…fuah…th-there's nothing there…!"

I beg to differ, Deku thought as he suckled, closing his eyes to focus on the sensations surrounding him. The wobbly slip-and-slide of Tatsumaki's fervent asscheeks, the heave of her chest against his face with each needy breath, the pinpricks of her nails on his head…and the sensations that rang out from her, too: his own fat fuckpillar throbbing between her asscheeks, its heat radiating into her oh-so-needy pussy, his rock-hard chest grinding against her belly while he squeezed her slender shoulders over him… They were driving each other into a state of overwhelming desire, making themselves immeasurably horny before the main event. Plap, plap, plap, plap! The noise of her ass colliding with Deku's pelvis was the lewdest sound Tatsumaki had ever heard her body produce. She moaned again, this time deep into his hair, while her eyes blurred and rolled back in their sockets. "Hnng…stupid…recruit…" she murmured. "Have you…had enough…of this…?"

"Just a moment," Deku said, and seized Miss Tatsumaki's slender waist tightly. She cried out as he started to lift and drop her violently, like a doll, slamming her ass down on his thighs with each powerful pump. He was using her asscheeks to jerk himself off, ramming his cock up her back all the way to her shoulderblades when her ass squished across his legs. The only reason she didn't destroy him immediately was the pleasure she felt radiating from his cock, the intense jolts of joy that leapt up her spine just as they did Deku's. As she bounced in his arms, Tatsumaki clung to his shoulders for dear life and chewed her bottom lip, drool dripping from her chin, totally helpless to stop what was happening--!

"Ungh! Ungh! Fffgh…" Deku suddenly lifted Tatsumaki clear away from his cock, just before the constant slapping of her asscheeks around his hilt could trigger a thundering orgasm. He fell back with her straddling his waist, both of them panting in the shadow of his upright, pulsing pillar. Tatsumaki glared into Deku's eyes , her chin on his collarbone, trying to look fierce even though her eyes were just as dazed as his. "You…insufferable…"

She didn't get a chance to finish that sentence, as Deku pushed Tatsumaki off of him and rose to his feet. She gasped and threw her ass high in the air, perking onto all fours as he grasped his cock in both hands and pumped it rhythmically. She looked like a true slut now, her thick ass and drooling pussy on full display, her tongue drooping from her mouth, panting for each precious breath…! She wanted to feel his cock inside her, just as much as he wanted to drive his giant fuckrod balls-deep in her tiny, crushing pussy and core her like an apple. As he lowered his broad, throbbing tip to her pussylips, she immediately pressed herself back, moaning as her gushing cunt squished across his pink cockhead, barely managing to force the very tip inside!

"Fffuck," Tatsumaki huffed. "Can you feel this…?"

"Y-Yeah," said Deku. "Can you…feel this?" He squeezed her right asscheek in his fist, squishing insurmountable banks of flesh between his fingers. Tatsumaki's back arched in a catlike gesture of pleasure, and she nodded while growling low in her throat. Deku let out a long exhale, then took hold of her handlebar hips and started to push forwards.

Insertion was…difficult, to say the least. The two lovers were totally mismatched in every way; Deku was just too damn big to fit in her pussy, and no one would have believed it possible for the two of them to come together, but they were both determined: as he pushed forwards and down, she pressed backwards and up, her slender back arching more and more as she struggled and strained and drove her knees into the ground. Soon her chest was grinding on the rooftop, her cheek pressed into a puddle of splooge, looking back over her shoulder as Deku leaned further and further over her…!

SCHLOP!

They gasped a high-pitched gasp as Deku's monstercock slid into Tatsumaki's delicious little pussy, gaping her out four or five times her natural limit! Her body stretched to accommodate him like a rubber glove several sizes too small; she'd never return to normal again, not after this. Her taut belly bulged out around the shape of Deku's cock, because it had no other choice; his girth was nearly as thick as her waist, and it forced her internal organs aside as it gouged all the way up to her cervix! "Hooohn!" she cried, pursing her lips while her eyes tipped back in an ahegao to end all ahegaos. Her thighs clenched madly, toes curling in her high heels as Deku tried to adjust to the incredible, tight squeeze. He was in just as dazed a state, his expression glazed with love and lust, his mouth open, panting thick breaths of air as he prepared himself for what came next…

He started to thrust, rocking his hips as slowly and steadily as he could at first, feeling her inner walls start to give way to his colossal cock. It was rough going; she squeezed him so tight that movement seemed almost impossible, and as he moved, the bulge in her belly, shifted back and forth back and forth… They struggled not to cum from the joint sensation of stretching and being stretched, but both of them knew it couldn't end here.

"O-Okay," Deku murmured at last, barely coherent in the depths of desire. "I'm…gonna go all-out. Are you ready?"

"Mrrgh…just hurry up and…do it," Tatsumaki hissed. A green glow emanated from her, bracing herself psychically. That was all Deku needed to see; a moment later, One For All's electricity crackled across his entire body, and he threw his hips forwards in a massive, powerful thrust! CLOP! Every inch of his cock vanished into Tatsumaki, bulging her almost to her chest as slick, clear cuntjuice fired in every direction! She squeaked and gurgled, but Deku was already drawing his hips back for another noisy thrust, and another, and another! SCHLOP, CLOP, CLOP, CLOP--! He pounded through her resistance, reshaping her insides with brutal power and precision. It was only with a heroic effort of willpower they kept themselves from cumming, knowing that their eventual orgasm would be strong enough to obliterate their minds. They rutted with all the force of monsters, SLAMMING hips to ass with all their strength. Each time they collided, sweat flew from Tatsumaki's rippling asscheeks, and she uttered a croaking note of bliss. "Fu-u-uck!" she choked through walls of blazing pleasure; she clawed the floor with both hands, and the cement of the roof started to crack as waves of psychic energy struck out from their rutting forms. She'd never felt this good in her life – and neither had Deku who by now was on the verge of weeping in his efforts not to cum. He pounded Miss Tatsumaki hard and fast, making his cock vanish into her hot, slurping pussy three of four times a second, his hips a blur! His balls flung back to collide with his own asscheeks before SCHLAPPING against her thighs, spanking her again and again and again! Drool and sweat added to the liquids flecking the floor, abundant evidence of the sheer ecstasy they shared.

Deku reached around Tatsumaki and hooked a hand into her mouth, tugging at her inner cheek while her tongue lashed across his knuckles. His other hand rested on her waist, holding her tight against his forceful thrusts. SCHLAP, SCHLAP, CLOP, SCHLAP~! He fired jolts of precum directly into her tiny womb, flooding her to the brim before he'd even hit his true orgasm. That moment was fast approaching, though, and both of them knew it. They were almost afraid of what was to come, but neither would shy away from the edge: they were about to experience the greatest pleasure of their lives.

"Fuck me – harder, you pervert!" Miss Tatsumaki hissed, trying and failing to lift her chest from the floor. Face-down, ass-up was the natural position for such intense breeding, her ass clapping and rippling wildly under the nonstop rampage of Deku's hips. "Nnghk!"

"Y-Yes, ma'am!" Deku cried out again, and One For All sparked even more frantically around him, pushing his movements to their absolute limit. His hips became a true blur – SCHLOP CLOP CLOP SCHLOP CLOP SCHLOP--! – while he fishhooked Tatsumaki's mouth and squeezed her waist even tighter. He couldn't fill his lungs with enough air to keep going; he had to end this now, and both of them knew it. Urged on by their encroaching twin-orgasm, Deku rammed the esper's fat ass without mercy, driving himself over the edge! "Oh--!"

Both of their eyes widened, then rolled back in a wild ahegao as they came at the exact same time, Tatsumaki squirting from her obscenely gaped pussy while Deku exploded a massive, bathtub-flooding load into her womb! Tatsumaki's tight little belly bloated like a beachball, swelling and swelling beneath her until it was forced outwards and around her hips; within moments, she was sprawling on her own gut like a waterbed, her face a mask of sheer pleasure. Deku kept thrusting over her, gurgling and moaning, clinging to the petite, overpowered little heroine as he bucked every – last – drop of his orgasm into her.

Afterwards, their sweaty bodies lay tangled in a heap, his on top of hers, neither of the two lovers saying a thing. Deku's hand brushed across Tatsumaki's waist and, hesitantly, he gave her a loose embrace. A moment later, her small hand gripped his bicep in a reciprocal gesture. They pulled together, and Deku shivered as her lips pressed against his chest.

"I expect more from you, next time we work together," she murmured under her breath, though she couldn't even muster the energy to be angry. Deku grinned and squeezed her tightly against him, content to linger with her in the afterglow.
