Frog Butt

MHA story featuring Deku and Tsuyu teaming up for an assignment...and promptly fucking like rabbits.

------------------------------------------------------------------------------------------------------------------------------------

Izuku gulped. When he'd been told he was pairing up with a partner for this mission, he hadn't expected to be sharing a room with her. Was the Hero Association really so low on funds? Izuku fumbled with the doorknob, and even dropped the key a few times before he managed to enter the room.

"Aha, here we are…"

Tsuyu seemed to be just as nervous as he was. She stared fixedly at the floor, as though she was trying to burn a hole in the carpet, and flushed bright red as she stepped over the threshold. "Ribbit…" Izuku couldn't help but notice the way her body moved in her tight, green suit. Her hips were just stunning, wide pendulums that couldn't help but bump into whatever they passed. And when she did pass, Izuku bit his lip and tried his best not to stare at those swinging shelfs of rump Tsuyu carried behind her. He heard her croaking nervously as she set her bags down. She was silent for a while. Then she said, in a small voice, "One bed."

Izuku turned. "Oh… Hey, it's okay! I'll sleep on the sofa."

"Ribbit." Tsuyu pushed a lock of straight, black hair from her eyes and glanced at Izuku. "We need our rest for tomorrow, so…you probably shouldn't."

Izuku nearly choked. Sleeping with– no, sleeping next to Tsuyu... The very idea made his head spin. He swallowed and, very gently, nodded. "I guess you're right. D-Don't worry; I won't do anything…anything…"

Tsuyu's cheeks turned even redder. She crossed her arms under her huge, perky chest and said, "Ribbit…"

-

Once they'd unpacked, there was nothing else to do but go to bed. Tsuyu stepped into the bathroom to undress first. Izuku sat on the edge of the bed, staring at the wall opposite the bathroom. His saliva was cold in his mouth, his fists tense in his lap. He couldn't help but imagine his teammate in there, peeling her suit off of her massive pudgy boobs, her butt… Tingly heat filled his body, and he squeezed his thighs together to prevent himself from getting too aroused…

When, finally, the door opened, Izuku was so wound up that he jolted to his feet. Tsuyu stood in striped PJs, her boobs stretching the fabric of her shirt so much that the hem lifted up over her bare belly. Her hips were on display, the dip of her pelvis… Izuku stared, his mouth slightly open, as Tsuyu hugged her arms around her chest and squirmed.

"I'll…I'll go…" Izuku murmured as he stepped past Tsuyu. The room was pretty cramped, and as he sidled by, her hip brushed over his bulging crotch, sending an electric sensation of pleasure up his spine. He all but staggered into the bathroom, and as he closed the door, he looked back and saw Tsuyu touching her hip, eyes wide in alarm.

-

When he returned in his PJs, Tsuyu was already in bed. Her body deformed the sheets in a way Izuku just couldn't ignore: lying on her back, her chest swelled upwards, rising and falling with each breath. The shapes of her hips and thighs were clearly displayed, too. Izuku could almost imagine she was nude under there. Blushing violently, he stepped around the bed and slowly inserted himself onto his side. The bed was even smaller than it looked: when he finally lodged himself in, he found himself gazing into Tsuyu's eyes, their faces just inches apart. She bit her soft bottom lip and shivered. From this position, he could even see down her shirt – right into the pale valley of her cleavage.

"Uh...ahn…" Izuku tried to relax, but it was difficult with Tsuyu's sweet scent drifting into his nostrils. "So…goodnight."

"Goodnight, ribbit."

-

Izuku must have fallen asleep at some point, because he woke up in the middle of the night. He blinked rapidly, not quite remembering where he was. He reached out for his All Might alarm clock, but his palm only found softness. He groaned gently. The warmth engulfed most of his head. He felt like he was drowning in marshmallows…

Then he focused, and remembered. His eyes went wide when he realised he was sprawling against Tsuyu, his head resting on her huge right breast. Her left leaned gently against his scalp, a warm and comforting weight. The fat bulge of a nipple poked his lips, stiffening as he breathed against it. Izuku tried to keep absolutely still. The rhythm of Tsuyu's breathing told him she was fast asleep: his head rose and fell on her gentle currents. Her left hand rested on his stomach, fingers curling against his rock-solid abs. She had a funny way of snoring: a soft, breathy 'kero, kero, kero' that made Izuku shiver with pleasure. Slowly, he closed his eyes again, lulled back to sleep by Tsuyu's body.

-

When Izuku woke again, it was early morning. Dawn light shone through a crack in the curtains. He rose and yawned, feeling utterly refreshed. He'd gotten a good night's sleep after all: all thanks to Tsuyu. He looked back at her sleeping form: her tongue hung out of her mouth and drooped all the way to the pillow, and her neck vibrated softly with each peaceful croak. Not wanting to wake her, Izuku tiptoed around the bed and into the bathroom, where he turned on the shower and undressed.

As soon as his boxers came off, he breathed a sigh of relief as his massive, veiny cock sprang from its restraints and flung a rope of precum against the shower wall. FLUMP! His own meat smacked his chest before swinging down again, a brutal case of morning wood. He winced and fondled his right nut as he stepped into the shower and turned it on. Hot water coursed over his naked, muscled body, peeling away the sweat of the night and pattering over his hyper-sensitive cock. Sleeping with– next to Tsuyu had left him raging down below, and now was his only chance to relieve himself. Grasping his rod two-handed, Deku groped and squeezed himself, his eyes losing focus with pleasure. He huffed and puffed, riding waves of bliss, pumping his giant schlong faster and harder. When he was close, he squatted down and aimed his tip at the drain. He hoped the hotel's pipes were strong enough!

The door opened. Deku gasped and stood – and released his giant cock. It sprang up in a mighty THROB and fired a rope of jizz across the room, hosing a dazed-looking Tsuyu's face and chest. She yelped and covered her face, hacking and spitting. She tried to step back, but slipped on a glob of semen at her feet. What happened next was a stumble for the history books: she cascaded forwards, throwing her arms out in an attempt to catch herself. Her boobs wobbled in her shirt with each lurching step. She cried out–

And plunged, face-first, onto Izuku's cock. Her yelp was cut short by his colossal rod entering her throat like a train entering a tunnel. Her momentum carried her forwards, stretching her sloppy, elastic gullet around his shaft until her face slammed into his pelvis with a loud, wet 'GLRK!'. The impact made Tsuyu's asscheeks surge free from the waistband of her PJ pants, bouncing into the open.

...And when Izuku felt that throat engulfing his cock, there was only one thing to do. His face a mask of pleasure, he grasped Tsuyu's hair and started to ram her face hard, wrecking her noisy throat with his giant cockpillar. "Ffuh! Hah..! Tsuyu..!" She grasped his hips tightly, almost clawing his skin as he brutalised her gullet. Each thrust made her tits swing and her asscheeks jiggle, grunting and croaking on his massive rod. Her neck bulged all the way down to her chest – and beyond, hitting her stomach with his broad cockhead, stirring her guts with his powerful facefuck. He kept pumping, kept jamming Tsuyu full of dick, until he hit the biggest orgasm of his life. Once the floodgates opened, there was no going back: he erupted inside her, flooding her stomach with a tide of thick white sludge. He wailed in bliss, sparks flashing behind his eyes as he washed Tsuyu's insides thoroughly with his spunk. Cum spurted from her asshole, slopping across the bathroom floor as the hot shower water continued to course over their twitching bodies. Her belly bloated outwards, straining her drenched PJ shirt so much that the buttons burst and her heavy cum-gut sprang free. Izuku came for almost three solid minutes, throbbing hard, blasting her stomach with dense jets of cream.

As he fired, Tsuyu grabbed his ass and dragged herself even tighter against his pelvis. When Izuku looked down into her eyes, they were full of need. Even as her belly distended and her ass jettisoned excess jizzz, Tsuyu rolled her thick, agile tongue out of her mouth and under Izuku's pulsing ballsack. When her tongue poked his asshole, he gulped and tensed. "H-Hey," he said, but it was too late. His eyes rolled back as Tsuyu's tongue launched up his ass, pumping his guts hard, grating on his prostate with persistent force. Izuku lost control. All For One's sparks cascaded through his body, and his next cumshot was so massive that Tsuyu's belly doubled in size – and her ass blasted a massive, artillery gush of cream, a tar-thick river sloshed across the floor.

At last, though, his load drained down to weak spurts that would have only filled wine glasses. Izuku's cock began to sag. Finally, he dragged his slimy schlong out of Tsuyu's sloppy gullet. She sagged on her hands and knees, trembling weakly as Izuku oozed the last few globs of his load over her head.

"Ah…I'll…" Izuku cleared his throat. He was still dizzy. "I'll be…in the bedroom…" With that, he awkwardly stepped over the cum-bloated frog girl and out of the bathroom, leaving her to wash.

Izuku sat on the edge of the bed, his hands folded between his knees, trembling faintly. What had he done? As the panes of bliss fell from his eyes, he started to feel a crushing guilt. His heart pounded, each beat a pulse of dread. He had to apologise – but how could he make up for that?

…He was dizzy. He couldn't think straight. It was only 5AM. The best thing he could do was go back to sleep…and think about this…when he was more lucid…

He laid back and closed his eyes, still trembling faintly.

-

Izuku awoke to a strange pressure around his cockhead. He cracked his eyelids and peered at the blurry shape rocking over him. "Buh..?"

"Come on, wake up already, ribbit…"

Izuku blinked rapidly. As his vision un-blurred, he saw that Tsuyu was on top of him, squatting with her bare, squishy pussy rocking over the raging tip of his steel-hard cock. Once she knew he was awake, she grinned and leaned over him, curling her hands in his dark-green hair. First, her pudgy titties squished against his chest, and then her lips crashed against his. Before he could react, her tongue filled his mouth and plunged down his throat. He gagged and spluttered, going wide-eyed as Tsuyu tickled the inside of his stomach, even when her lips parted from his. "Aghn..?"

Tsuyu reached down and gave his rigid mast a squeeze. Her belly was still bloated with jizz. If not for her froglike physiology, she might have burst. She gave a contented croak that vibrated through her tongue before shifting her hips - and mounting her tight, winking asshole on his tip. "Keep up, Izuku," she said, her voice slightly slurred due to having her tongue lodged in her lover's stomach. "I'm going to make you mine…"

When she bucked her hips, Izuku cried out - half of his cock swallowed up in her ridiculous ass. Her eyes rolled in bliss, and she whipped her tongue all the way out of him so it could swish and curl against the air, shiny and pink and expressive. Izuku could only grasp her powerful thighs as she rode him, jerking her sphincter up and down his shaft, clenching her guts around his tremendous meat. Her asscheeks clopped together with each ferocious buck, almost twerking on his cock.

"Tsuyu..!" Izuku cried, squirming beneath her. "I-I'm sorry about before. I–"

"Sorry?" Tsuyu seemed puzzled. She trailed her tongue against his cheek, then pushed it into his ear for a quick swirl. "But I wanted to taste your thing, Izuku."

"Hhah…you did?"

"And now I'm tasting it in other ways." Tsuyu's belly sloshed loudly as she pumped her hips, churning and stirring all that spunk inside her. Izuku wondered how she'd possibly digest all of his cum - but then her eyes sharpened, and she gurgled, and her cheeks bulged…and she puked spunk all over his chest. Her belly shrank just a little. "Hgglrrurk! Hhah…hah…ribbit…that's a shame…I wanted to hold it all in…"

Izuku sank his fingers into her doughy asscheeks and sat up, growling in pleasure. He started to work Tsuyu's hips up and down by force, shocking her with his strength. All For One fluctuated in his arms, his cock… When he squeezed and RAMMED her all the way down to his hilt, Tsuyu cried out and puked another thick load of jizz down Izuku's abdomen. When her tongue tried to dive down his throat again, he grabbed it in a fist and wrapped it around Tsuyu's neck, pulling tight. "In that case…I'll just put another load in you, and make sure it stays in!"

Izuku hooked his arms under Tsuyu's thighs and stood, lifting her off the bed. He carried her to the window and pressed her against the pane - then started to ram her hard and fast, clapping his balls against her asscheeks with every thrust!

"R-Ribbit..! Someone will see!" Tsuyu wailed. Her naked boobs bounced between their chest, sloppy and sweaty and shiny. Izuku just tugged her tongue tighter, and she gargled in mute bliss as he hammered her ass into oblivion.

"This time," Izuku said, "you're gonna digest every drop…to make your boobs and butt bigger."

"Hgghk…ribbit…nnhm, okayyy…"

Izuku adjusted his grip, seizing Tsuyu's asscheeks directly and pounding up into her twitching hole. Her tongue unwrapped from her neck and curled around his right bicep, holding on for dear life as she moaned and rolled her eyes and made all kinds of sloppy, slutty expressions. When Izuku turned and threw her back down on the bed, she blinked at him in shock – until he drove his weight down on her, pancaking her tits under his chest and shoving her knees against her shoulders. Locked in a mating press, Tsuyu could do nothing but wail and croak as the pressure grew and grew – until, finally, she hit a squealing, ribbiting orgasm that shook the bed and reverberated off the walls. Izuku released her legs, and they immediately wrapped around his waist, squeezing him almost painfully against her, cramming every last inch of his pole into her tight, clenching asshole.

It was all too much. At last, Izuku groaned, arched his shoulderblades, and hit his own orgasm. He erupted into her, just like before, and bloated her belly massively over the course of a three-minute jizz-blast. She tossed her head from side to side, and when her neck rumbled and her cheeks started to bloat, Izuku clamped a hand over her mouth to stop her from puking up more jizz. Instead, her neck swelled outwards, bigger and bigger, bloating with jizz like a frog's neck bloats with air. Her eyes rolled back, watering thickly…and with a powerful spasm of muscle, she swallowed, and her neck shrank back to its normal, slim size.

When Izuku pulled out of Tsuyu, her belly looked three years pregnant, jutting up toward the ceiling in a huge, curved, gurgling mound full off rich, white jizz. She gurgled faintly, still rolling her head from side to side, her tongue snaking out to stroke her own oversized belly. Izuku stepped back and wiped his brow, breathing sharp breaths. How was he going to explain this to his teammates?

-

Uraraka ran out to meet them at the front gate. Her boobs bounced in her shirt until she came to a halt, and they heaved heavily as she gasped for air. "Ha…ha…hi there, you guys! How was your mission?"

"Pretty great!" said Izuku, smiling wide. "It's good to see you again." But Uraraka wasn't looking at him: she'd spotted Tsuyu's belly, swollen in her tight, green hero suit. It had shrank significantly since Izuku had pumped her, and her breasts and ass stuck out fatter and thicker than before, but she still looked nine months pregnant at least.

"Hey, Tsuyu…"

Tsuyu tilted her head and touched a finger to her chin. "Hmm?"

"I, uh…did you get a haircut, or something?"

"No, but Izuku fucked me stupid and inflated my belly with his jizz. Ribbit."

Uraraka stared, her brain not quite processing what she'd just heard. She stood there for a long time, gazing straight ahead, even after Izuku and Tsuyu had walked past her and into the UA building. Almost an hour later, Uraraka blinked and said, "Eh?"
