Deku grinned, fascinated with the way his cock disappeared into Kacchan’s greedy hole. “Look at you, the number one hero, Dynamight, kneeling on all fours and presenting like a good little bitch. Mmm, feels so good. Fuck, you take my cock so well, your ass is sucking me in like a desperate whore. Are you that hungry for my cum, Slut?”
“Y-Yes, ‘Zuku,” Katsuki’s voice cracked.
SMACK. “That’s not my name!” Izuku growled as his hand came down to strike the hero’s ass again. Katsuki shuddered beneath him with a broken cry, cock drooling onto the cement floor and ass clenching. Fuck, Izuku wouldn’t be able to hold back much longer. “How are you supposed to answer me, Slut?”
“S-Sir,” Katsuki rasped out, thighs shaking after nearly an hour on his knees before they even started. “I want your cum, Sir.”
“That’s a good boy,” Izuku cooed, restarting his pace of slowly pulling out and slamming back in hard. “Don’t forget again or I won’t let you cum.” Katsuki choked on a sob, shoulders trembling as he tried to stay upright. If he dropped to his forearms, the villain would punish him again.
Whenever he’d fantasized about his long-time crush, he always assumed Kacchan would be the quiet type, just gasping breaths and small grunts. Oh how wrong he’d been, quickly learning after their first time just how loud the hero could be. “What would your annoying little fans think if they saw you now, crying on my cock?” Katsuki whined low, hole clenching around Deku’s dick. “Oh, does my cum slut like that? Does the little hero want to be caught begging for his greatest adversary’s cock?”
“Yes, Sir,” Katsuki sobbed, shuddering as Izuku picked up the pace, pounding into his ass. With his knees surely numb and throbbing, it truly was a testament to the hero’s strength that he could stay upright. “Yes, I want them to see. Want them to know how much I love your cock!”
“What a fucking whore!” Deku laughed as he felt himself hurtling toward the edge. The thought of Kacchan loving his dick so much he’d risk his career, his dream, sent a thrill through him like no other. “Get ready, my little slut. Don’t you dare waste a single drop.”
“I won’t, I promise,” the hero sobbed, shaking his head frantically. “Please, give it to me. I want your cum. I want it, Sir!”
Viridian eyes rolled as Izuku slammed in, balls slapping against Katsuki’s ass, and spilled deep inside. Fingers gripped his little slut’s hips, tugging him back farther with a need to be as deep as possible, spasming and gasping through his orgasm. When he pulled out, huffing to catch his breath, he noticed how angry red and rock hard Kacchan still was, pre dripping in a steady stream from his slit to the floor. Izuku had to keep himself from moaning loudly at the way the blonde’s hole clenched around nothing, cum beginning to leak out.
“Thank you, Sir,” the hero shuddered, hands readjusting to keep his back straight, not wanting to lose any of the villain’s seed.
“Good boy,” Izuku grinned, running a hand through sweaty blonde locks. “Keeping it all in.” The villain took a few steps to the cushy velvet couch on the opposite side of the room, slumping down and taking a deep breath. Katsuki’s face was colored deep red, arms shaking with the effort of holding the same position for so long. “Come,” Deku ordered, curling his finger.
Scarlet eyes stared at him for a moment, as if he were having a hard time processing the command. He groaned, joints popping as he started to stand. Deku was on him in a second, foot jamming against the hero’s shoulder and forcing him back on all fours.
“Did I say you could stand, Slut?” He shouted and bent to wrap his fingers around Katsuki’s throbbing member, the head an angry purple. The hero sobbed, thrusting into the fist, and cried out when Deku tightly gripped the base. “Disobedient heroes don’t get to cum!” He released his dick and sauntered back to the couch, sitting heavily and opening his legs. “Crawl and maybe I’ll think about going easy on you.”
Emerald eyes tracked the hero’s every move. Nothing went unnoticed, from the flinch on pain every time Katsuki put weight on his knees to the way his cock bobbed and pulsed with need. He ended between Deku’s thighs, vermillion eyes glassy with unshed tears, desperate for relief. Izuku swore softly under his breath, dick filling out again.
“Open,” he ordered and Kacchan’s jaw fell, tongue poking out. Izuku placed the heavy head of his cock on Katsuki’s tongue and the hero moaned. “What a good little bitch, so eager to clean.” He pushed in further, loving the sounds his slutty little hero made. Kacchan’s gaze turn confused when he didn’t move anymore than an inch. Deku smiled softly, “Keep me warm.” Understanding flashed across the hero’s face, lips closing around the dick in his mouth.
Izuku sighed and leaned back, enjoying the show. Kacchan’s face was still deeply flushed, the occasional moan or hum giving away how aroused he was, brows flinching every so often as his cock throbbed painfully. He moved, sliding his lips over the villain’s dick and Deku hissed.
“What’s wrong, Slut? Can’t hold me without wanting to suck? Does it taste that good? Just can’t help yourself. Greedy little hero so desperate for my cock. I honestly can’t decide what I like more, your lips wrapped around me or having your tight ass sucking me in.”
Katsuki moaned low, eyes starting to become unfocused as drool flooded out of the seal he’d formed around Deku’s dick. Freckled fingers gripped the back of the hero’s head and the villain thrust his cock into the blonde’s waiting throat. Katsuki choked and gagged loudly, hand snapping out to grip Izuku’s calf hard, pinching his skin. The greenette understood the silent signal immediately… slow down . He pulled back, allowing the blonde to breathe and when the hold around his leg loosened, the hero returning his hand to the floor, Deku thrust back in again. He set a slow pace, enjoying the feel of Katsuki’s tongue along the underside of his cock, the feel of his throat massaging and clenching around him with each thrust. But most of all he loved the tears that dripped down pale cheeks, the desperate moans of his little slut. Fuck, he was close.
“Touch yourself,” Izuku ordered, taking mercy on the hero.
Kacchan’s hands couldn’t move fast enough, slender fingers wrapping around his length. He stroked once, and the most depraved sound vibrated along Deku’s cock. The villain shuddered, gripping a handful of sweaty blonde hair and fucked into Katsuki’s mouth.
“Look at my pretty little hero,” he crooned. “So drunk off my cock, so desperate for my cum in his belly.” Kacchan whined, eyes squeezing shut and forcing fat tears down his cheeks as he furiously stroked his pulsing erection. A few more pumps and he was spilling all over the floor, sobs muffled by Deku’s cock cumming down his throat.
Izuku pulled out and sighed. One look at Kacchan’s glassy red eyes, pupils blown wide, had him helping the hero onto the floor, easing his legs out of the bent position. The hero whined as his joints cracked and popped, no doubt screaming in pain.
“Shh, it’s okay,” the greenette cooed. “My perfect little hero took care of me so well. And now it’s my turn to take care of you.” Freckled hands massaged feeling back into Katsuki’s limbs before grabbing the Afghan blanket from the back of the couch and tucking it snuggly around the hero. “Such a good boy,” he praised.
Izuku knew he had to work fast knowing Kacchan would need the utmost care now that he’d hit subspace. With the tub filling in the other room, he returned to Katsuki and helped him sit up. The hero was dazed, able to move, but needing to be guided. It was always a bit of a challenge, helping Kacchan get around, since the blonde was more than a head taller than Deku and his muscles made him incredibly heavy. But with a bit of finesse, Izuku got him in the tub, following soon after and cradling the larger man against his chest.
Hands carded through soft locks while lips caressed any available skin. Katsuki hummed in his embrace, thick hand raising to cover Izuku’s. The freckled man threaded their fingers together and brought their clasped hands to his mouth so he could place a long kiss against Kacchan’s knuckles.
“Welcome back,” he hummed softly. The hero groaned and settled against Deku. “Feeling alright?”
“Fucking amazing,” Katsuki sighed. “Knees hurt a bit, but fuck, I’m so relaxed.”
“Good,” Izuku chirped, pressing a kiss into the other man’s temple. “I got a little worried toward the end. We haven’t gone that hard in a while.”
“It was good,” the blonde mumbled, barely able to keep his eyes open. “Really fucking good.”
Izuku smiled. Their nights together had become infrequent since the Hero Commission started looking into Dynamight, suspicious of his activities outside his agency. It was stressing Kacchan out, and the paranoia had him sleeping less, more likely to screw up while on duty. And though he worried the Commission was getting closer to learning about his relationship with the most notorious villain in Japan, desperate times called for desperate measures. Deku was thrilled when Kacchan reached out. Promises of seeing his favorite hero always got him excited. The freckled villain hoped the Commission never learned about their nights together, never tried to tear them apart. He would burn down the whole world to keep Kacchan by his side.
