The only sound in the room was the forced hum of the air conditioner fighting against the heat they had generated themselves.
Yu Takeyama was sprawled on the sofa, with one arm covering her eyes and one leg dangling onto the rug, her toes brushing the floor. Her chest rose and fell, glistening with sweat.
Izuku was sitting on the floor, his back resting against the TV stand, spinning a water bottle between his hands.
"Izuku," Yu called out. Her voice sounded raspy, lacking the power she used in front of the cameras.
"I'm listening."
"If you stay silent staring at me like I'm a puzzle missing pieces again, I'm firing you. Seriously. I'm calling HR."
Izuku let out a short laugh. He unscrewed the cap of the bottle.
"I wasn't analyzing anything. I just... like the view. The angle from down here is interesting."
Yu moved her arm from her face. Her eye makeup was slightly smudged, and her blonde hair was a bird's nest around her horns. She tried to put on that look of superiority she used with villains, but the flush on her neck and chest gave her away.
"You are a dirty flatterer," she murmured, stretching her hand out to him without getting up. "Give me that. I'm drying out."
Izuku stood up, towering over the sofa, looking down at her.
"Please?" he suggested.
Yu narrowed her eyes.
"I am your boss. That is an order."
"We are outside business hours. And technically, you are in the middle of a voluntary physical audit." Izuku brought the bottle close to her lips but pulled it back an inch when she tried to drink. "Say it."
Yu huffed, hitting the cushion with her fist.
"Please, you damn sadistic nerd. Give me the water."
Izuku smiled and brought the bottle to her mouth. Yu propped herself up slightly on her elbows and drank eagerly. The water spilled from the corners of her mouth, running down her chin, tracing a line down her neck until it fell into the valley between her breasts.
Izuku followed the drop with his gaze. He did not hide it.
"Done." Yu pushed the bottle away, panting. She wiped the back of her hand across her mouth. "Happy? You've hydrated me. Now stop looking at my tits weirdly."
"It's relevant data." Izuku set the bottle on the coffee table with a sharp thud. "Think you've caught your breath? You said you wanted to test the limits."
Yu let herself fall back again, staring at the ceiling.
"Shut up. My limits are fine. It's the sofa I'm worried about."
Izuku looked down. The front right leg of the furniture was tilted at an unnatural angle. The wood creaked when Yu adjusted herself.
"I think the warranty doesn't cover this," Izuku pointed out.
"It cost me a fortune. It was Italian," Yu complained, pouting. She lifted a leg and gave Izuku a soft kick on the thigh. "You're going to have to pay for it. Deduct it from your fees."
Izuku grabbed her ankle in mid-air.
"I have other ways to pay," he said quietly. He caressed her ankle bone with his thumb.
Yu shivered. She tried to pull her leg back, but he didn't let go.
"You've become so confident, Midoriya," she whispered. Her voice trembled a little. "No, wait... you were always a pervert."
"I adapt quickly to the environment." Izuku tugged gently on her leg, dragging her a few inches toward the edge of the sofa. "Besides, I have a demanding boss."
"The best," she corrected. She bit her lower lip, watching his hand travel up her calf. "But not here. If we break the sofa completely, I'll have to sit on the floor to watch the news. And I refuse to sink that low."
"Fine," Izuku accepted. "To the bed then."
"Wait." Yu tried to sit up. She winced. "Ugh. My legs feel like jelly. I think you went too far."
"I was gentle."
"Well, my hips disagree." She stood up, swaying slightly. She grabbed the back of the sofa to keep her balance. "I need a shower. I'm sticky."
She took a step toward the hallway.
Izuku moved fast. He cut off her path, grabbing her by the waist and pressing her against his body.
"No," he said against her ear.
Yu tensed, but her hands automatically went to his shoulders.
"Excuse me? Are you giving me orders in my own house?"
"I like you like this."
"You are a pig," she blurted out, but she tilted her head to give him more access. "An obsessive pervert."
"And you love it."
Yu let out a nervous giggle.
"Maybe. A little." She wrapped her arms around his neck. "Okay. But I am not walking to the bedroom. My knees are shaking and it's your fault, so take responsibility."
"With pleasure."
Izuku crouched and lifted her into his arms as if she weighed nothing. Yu let out a stifled squeak and hid her face in the crook of his neck.
"Don't look at my face too much," she murmured against his skin as he walked down the hall. "My mascara must look like a raccoon mask."
"You look beautiful," Izuku replied firmly.
"Shut up. I look like a disaster."
"You are the number one hero in the male popularity polls. Even as a disaster you are unattainable."
Yu lifted her head and looked at him. She smiled, that arrogant smile Izuku knew so well.
"Good point. I am unattainable." She squeezed his bicep. "But you have me in your arms. Feel lucky."
"I feel lucky," he admitted.
They reached the bedroom. Izuku pushed the door open with his foot. The room was in semi-darkness, lit only by the street light coming through the window. The King Size bed occupied the center, an island of silk sheets that was still perfectly made.
Izuku walked over and dropped her onto the mattress. Yu bounced a little, letting out a laugh. She rolled until she was in the center and stretched, deliberately arching her back. The bunny suit she had put back on to seduce him tightened over her breasts.
"Alright, Consultant," she said, looking up at him. "We are here. What is the next item on the agenda?"
Izuku stood at the edge of the bed.
"In-depth data collection," he said.
Yu licked her lips seeing him naked.
"Sounds boring."
"It won't be."
Izuku climbed onto the bed, crawling over her. Yu instinctively opened her legs to make room for him. He positioned himself between her thighs. He stared at her chest.
Izuku lowered his head. He used his teeth to grab the edge of the suit over her left breast and pulled gently.
"Hey! That's delicate!" Yu protested, raising her hands.
"Shh."
Izuku released the fabric and licked the skin that had been exposed. Yu shuddered, digging her heels into the mattress.
He went lower. He kissed her navel, and kept going down to the bottom edge of the suit. Yu lifted her hips, impatient.
"Take it off," she asked. "It's in the way."
"No." Izuku grabbed her thighs and spread them further. "Leave it on this time. I want to see how you react with it."
"Izuku!"
He buried his face between her legs, right over the damp fabric of the crotch. He blew hot air through the material.
"Ah!" Yu screamed, throwing her head back against the pillow. "That's cheating! That doesn't count!"
"Everything counts," he murmured against her.
Izuku pushed the fabric aside with his nose, looking for her center. He found it. It was hot and soft. Yu moaned, a long, broken sound, and her hands came down to grab his green hair.
"Wait... wait, Izuku..."
He didn't wait. He started using his tongue, slow at first, tracing wide circles.
Shit... Yu squeezed her eyes shut. Shit, Izuku... that is...
"How does it feel?" he asked, vibrating against her skin. "Is the data positive?"
"Shut up with the damn data!" she screamed, pulling his hair. "Just keep going! There! Right there!"
Izuku obeyed, but changed the pace. He stopped being gentle. His tongue became firm, rhythmic. Yu started shaking her hips, trying to escape and seeking more pressure at the same time.
"Ngh!"
Izuku slipped two fingers inside her while his tongue kept working on the outside. Yu let out a stifled scream.
"Ahhh! That's it!"
Her body tensed. Her thighs closed around Izuku's head, squeezing tight. Superhuman strength.
Izuku increased the speed. Yu started babbling nonsense, mixing insults with pleas.
"Izuku! I'm going to...!"
The orgasm hit her suddenly. Yu arched her back so much that only her shoulders and heels touched the bed. She screamed his name, a high-pitched sound the neighbors surely heard. She convulsed violently for a few eternal seconds and then collapsed against the mattress, panting as if she had run a marathon.
Izuku pulled away slowly. He wiped his mouth with his forearm and crawled up until he was face to face with her.
"Well?" he asked, with a satisfied smile.
Yu looked at him with half-closed eyes. Her chest was red and sweaty.
"I hate you," she whispered weakly. "I hate you so much."
"I love you too."
Izuku kissed her. A slow, deep kiss, tasting his own work on her lips. Yu responded lazily at first, but soon her arms wrapped around his neck and she pulled him close.
"We aren't finished," she said against his mouth. "Not even close."
"I know."
Yu pushed him so he was sitting on his heels. She sat up and pushed him back, making him lie down.
"My turn," she declared. "It's your turn to suffer."
She straddled him. The bunny suit was a mess, twisted and damp, which made her look even more erotic in Izuku's eyes.
"Are you going to take control?" he asked, putting his hands on her hips. "Careful, Mount Lady. The terrain is unstable."
"Shut up. I'm going to conquer you."
Yu rose onto her knees. She grabbed Izuku and guided him towards her entrance.
"Look at me," she ordered. "Don't close your eyes."
"I couldn't even if I wanted to."
She lowered herself slowly. When he entered her, Yu let out a shaky sigh and let her head drop back, exposing her long, pale neck.
"God... Izuku..."
"You're very tight," he groaned, gritting his teeth. "Relax a little."
"I don't want to," she hissed, going down to the hilt. "I want to feel everything. I want it to hurt a little."
She started to move. It was a possessive, territorial movement. Yu dug her nails into Izuku's chest, marking his skin.
The rhythm increased. The bed frame started to creak, a metallic, rhythmic sound filling the room.
"Faster," Yu asked. She leaned forward, resting her hands on his chest. Her blonde hair fell like a curtain around both their faces. "Make it count, Izuku!"
"You want more?"
"Yes! Use your Quirk! Now!"
Izuku activated his Quirk. Green lightning bolts coursed across his skin. He grabbed Yu's hips firmly and increased the power of his thrusts.
"AHHH!" Yu screamed. "It's too strong!"
The room filled with the sound of skin colliding, wood creaking, and their own cries. The friction was intense, almost painful, but addictive.
"Yu! Look at me!"
She opened her eyes. Her pupils were dilated to the max. There was something wild in her gaze, something that wasn't human.
"I feel... I feel something..." she gasped. Her skin started to heat up drastically.
"What's wrong?" Izuku noticed the temperature rising.
"It's too much! It's a lot of energy!" Yu was moving frantically, losing coordination. "I can't... I can't contain it!"
"Let it out!" Izuku shouted. "Let go!"
"You don't understand!" Yu grabbed his shoulders. Her hands seemed heavier. "My Quirk! It's reacting!"
"What?"
"I feel... big!"
The pleasure reached its critical point. Yu screamed, a sound that vibrated the window panes.
And then, the world changed scale.
CRACK!
The sound was like a cannon shot in the closed room.
In a blink, the weight on Izuku multiplied exponentially. The ceiling seemed to come down, or rather, Yu went up.
The bed didn't stand a chance. The wooden legs exploded, sending splinters flying like shrapnel. The frame snapped in half with a metallic wail.
They both fell to the floor amidst a cloud of dust and destruction.
"Shit!" Yu shouted. Her voice sounded deeper, with more resonance.
Izuku coughed, brushing a piece of wood off his face. He opened his eyes.
Yu was no longer his size. She was on all fours over him, but her hands were huge, sunk into the ruined carpet. Her head grazed the ceiling lamp. She was at least eight feet tall.
"Yu..." Izuku blinked, looking up. Her breasts were massive, hanging over him like a delicious threat. "...you grew."
"I know!" she screamed, trying to move. The floor creaked under her knee. "I can't... I can't shrink! The arousal blocked the reversion control!"
"Blockage due to dopamine overload?" Izuku, incredibly, seemed fascinated instead of scared. He touched her thigh, soft but resistant to the touch. "Your muscle density has tripled."
"Stop analyzing me and help me!" Yu tried to get up, but her size in the small room made every movement clumsy and destructive. Her hip hit the nightstand and turned it into dust. "I'm going to break the building!"
"Don't move," Izuku ordered.
"I'm crushing you!"
"No, you aren't."
Izuku pushed upward.
"What are you doing?" Yu asked, looking down.
"Adapting to the new terrain," he growled.
With a titanic effort, Izuku slid out from under her and stood up. He reached the height of her chest. The scale was ridiculous and exciting.
"You're huge," he said, looking at her with hunger.
"I'm a monster," Yu moaned, covering her face with her hands. "Look at me. I destroyed the bed. I'm a disaster."
Izuku pulled her hands away from her face with force.
"You are magnificent."
He pushed her back, forcing her to lean against the cracked wall.
"Izuku?"
"You said you wanted brute force," he said, his voice dark. "Well, now you have the size to handle it."
"Wait... are you going to...?"
"I'm going to continue. We aren't finished."
Izuku stepped closer. The height difference made the logistics complicated, but not impossible. Yu was half-sitting, half-leaning on the wall, her legs spread.
Izuku entered her again.
"AHHH!" Yu's scream made the window panes vibrate.
The sensation was different now. She was bigger, stronger, and her internal muscles squeezed with a force that would have decapitated a normal man. But for some strange reason that didn't affect Izuku.
"You are very tight!" Izuku growled, thrusting with all his weight.
"You are very small!" she retorted, panting. "I feel like I'm losing you!"
"Oh, yeah?"
Green lightning illuminated the dark room. He increased the speed, generating more pleasure in Yu.
"OH GOD!" Yu clung to his shoulders. Her nails, now larger and harder, tore the skin of Izuku's back, but he didn't even flinch. "Ngh! Ah! Faster!"
The friction generated a strange energy. A violet aura began to emanate from Yu, mixing with Izuku's green lightning.
"What is that?" Yu asked, watching the violet light run up Izuku's arms.
"Energy transfer," he gasped. "Your Quirk... is reacting to mine."
"It feels... hot."
"It's power," Izuku corrected.
Suddenly, the skin on Yu's thighs began to change. Grey patches appeared, spreading rapidly.
"Izuku... my skin..."
"I see it."
The skin hardened, turning into a layer of polished, shiny rock. A natural armor.
"Am I turning into a statue?" she screamed, panicked.
"No. It's an automatic defense. Your body is trying to contain the energy." Izuku ran his hand over her hip. The rock was rough, cold, a brutal contrast to the heat inside her. "It's incredible."
"It's horrible! I look like a gargoyle!"
"You are the sexiest gargoyle I have ever seen." Izuku bit her neck, right where the soft skin met the rock armor. "And now I can be as rough as I want without breaking you."
"Breaking me?" Yu laughed, a wild laugh distorted by her size. "Try it, brat! Break me if you can!"
She pushed back against the wall. The plaster gave way, revealing the bricks.
The thrust was brutal. Izuku grabbed onto the rock plates of her waist for leverage. The sound of skin against skin mixed with the crunch of stone and Yu's moans.
"More! Harder!" Yu screamed. "Don't stop!"
"I am not going to stop!"
The room shook. Literally.
"I'm gonna come!" Yu warned. "Izuku, get away, I don't know what's going to happen!"
"I'm not leaving!"
"I'm going to crush you!"
"Take the risk!"
Yu screamed. Her body arched, peeling away from the wall. The violet energy exploded outwards.
At the same time, Izuku let go. The release was mutual.
And then, chaos.
At the moment of climax, Yu's concentration evaporated completely. The Quirk collapsed.
"WOAH!"
Her body shrank instantly. From eight feet down to her usual five-five.
Izuku, who was clinging to her, lost his foothold. They fell forward, rolling over the remains of the bed.
The rock armor crumbled into fine dust instantly, covering them both in a layer of gray sand.
They lay on the floor, tangled in torn sheets and pieces of wood, coughing in the cloud of dust.
Silence. This time, a stunned silence.
Izuku was the first to move. He sat up, shaking the dust from his hair. He looked like a gray ghost. He looked around.
The room looked like a war zone. There was no bed. The wall had a hole in the shape of Yu's back. The ceiling lamp hung by a wire.
Yu sat up slowly, coughing. She looked at her hands, then looked at Izuku, then looked at the room.
"Izuku," she said, with a very calm voice.
"Yes?"
"Tell me you have a plan to explain this to whoever comes to repair our disaster."
Izuku looked at the hole in the wall. You could see a bit of the hallway through the cracks.
"Termites?" he suggested.
Yu stared at him for three seconds. Then, she let out a laugh. A loud, clean, hysterical laugh. She let herself fall back, onto the pile of sawdust and fabric that used to be a luxury mattress.
"Termites," she repeated, laughing. "Giant termites with gigantification Quirks."
Izuku smiled and lay down beside her, ignoring a plank digging into his back.
"Technically, we wouldn't be lying about the 'giant' part."
Yu turned to him and ran a dusty finger down his cheek.
"You're a mess."
"You look like a statue that just came to life," he replied.
"Shut up." She moved closer and rested her head on his chest. "Hey."
"What?"
"Next time..." Yu traced circles on his chest. "...we go to a hotel. One with natural disaster insurance."
"Noted in the log."
"And Izuku..."
"Hmm?"
"That rock armor thing..." She looked up, biting her lip. "It was weird. But I didn't dislike it."
Izuku kissed her dust-covered forehead.
"I know. Who are you kidding? You got off on all this."
"You're an idiot."
"I'm your idiot."
"Yes," Yu sighed, closing her eyes. "I guess so. Now go to sleep before I realize how much it's going to cost to fix this and kill you."
"Goodnight, Yu."
"Goodnight, my dear Izuku."
And there, amidst the ruins of the room, they fell asleep, covered in dust and satisfaction.

Author's Note:
"Termites." Really, Izuku? Termites with a gigantification Quirk? I'm pretty sure if they try to file that claim, the insurance agent is just going to look at the hole in the wall, look at Yu, and immediately resign.
Also, we apparently unlocked "Gargoyle Mode" today. I didn't know Rock-Hard Armor was going to be a new fetish tag for this story, but here we are. You're welcome?
Thank you so much for the support, guys! Your pledges are literally the only thing keeping Yu from going bankrupt on home repairs right now. See you in the next chapter (hopefully in a room with reinforced steel walls)!
