Izuku had thought, for sure, he knew his lot in life. That his love for the Lord had guided him onto

the right path, leading him to the seminary he called his home. Where he found peace in his studies, excited for the day he too would be able to lead the lost onto the righteous path. He had known who he was, and he was content.

Until Katsuki Bakugou was assigned as his new

roommate, that is.

He had had those lustful feelings for other men before, had struggled and prayed and cried over them as he tried to find where in the Lord’s plan he would fit. Had conversed with his mother, with Father Yagi at his church, had confessed and hoped that some

level of salvation would be granted upon him. Even when told there was no sin to forgive, he had still fought, still shied away from the way meeting the gaze of certain men would warm his blood and stir his stomach, leaving him flushed and fighting the urge to find release in the

darkness of his room. For the most part he had gained a control his teenage self had never known, and in the safety of the Lord’s embrace he had found peace.

It helped that many of his fellow students were...𝑖𝑛𝑡𝑒𝑟𝑒𝑠𝑡𝑖𝑛𝑔 characters, to put it kindly, and he would leave

it at that. It was not his place to judge, that was the Lord’s purview and his alone, but it did make it easier on his dick.

But Katsuki was 𝑑𝑖𝑓𝑓𝑒𝑟𝑒𝑛𝑡. There was something about him that drew Izuku towards him, that made him want to be around him despite the stirrings

he could feel inside. It wasn’t just his looks, though those blazing red eyes had made him mourn the lack of privacy more than once. It was the way he talked, the way vulgarities fell from his lips so easily even as he recited the prayers from heart in the next breath without

break, flipping from personal to professional with ease. How their conversations could last hours and he still felt the need to talk to him, to dive into the depths of Katsuki’s mind and pull out every thought he had ever had. How the occasional brush of their bodies when they

were getting ready for the day in their far too small shared room had him rushing to leave, because staying would mean 𝑡ℎ𝑖𝑛𝑔𝑠.

Father Yagi might have been the one to point him towards the church, implying he might find the peace he searched for there, but Katsuki was the

one he strived towards, in so many more ways than one.

He'd convinced himself he could be happy with friendship. So sure that, once they were out of close quarters, he could get all of this back under control, and could look at Katsuki with a pure heart once again, something

fitting of their calling as men of the Lord. Their rooming situation was only for the year, and once that time had passed he would have someone like his previous roommate. Someone calming, someone he could have a pleasant conversation with without that burning 𝑛𝑒𝑒𝑑 to talk.

And whatever this was with Katsuki would fade into the back of his mind, disappearing as distance took hold. Izuku was sure.

Only for Katsuki to kiss him. For Katsuki to cup his face between his hands in the middle of one of his muttering rambles about theology and mythology and

the millenia old connections, cutting him off midword by swiping his thumb across his lip. For Katsuki to close that distance between them, mouth burning and sweet, finally letting Izuku understand the temptation of the apple and the 𝑟𝑢𝑠ℎ as he gave in, as his own hands

reached up to tangle into hair that was just as soft as he’d hoped the first time he saw it. For Katsuki to bring tumbling down every stone Izuku had built himself upon, because that single kiss his first kiss left him shaking and panting and wanting more, wanting to devote

himself to the man half bent over him so he could accept whatever he was given.

“I’ve been wanting to do that since I first saw your stupid face,” Katsuki breathed, lips running along his chin, his cheeks, light peppering of kisses up to the creases around his eyes that Izuku

hadn’t even realized had appeared, that only showed up when he was smiling. Because he was, smiling, smiling and giggling as he let Katsuki kiss him, fingers turning his face for new angles to find new freckles he had yet to lay claim as his own. “Transferred to this place to be

holy or whatever shit and they immediately put me with the hottest piece of ass I’ve ever seen, and then you had to go and be fucking 𝑐𝑢𝑡𝑒 on top of it. Gave me that feelings bullcrap. Bastard. Asshole.”

Izuku only laughed as Katsuki kissed him again, this time parting his lips because how could he resist? He knew he should - should accept he had been led into temptation once, even the strongest of men faltered, but he should step back, put distance between them, make it clear

that as a man of the Lord he could not accept the feelings so clearly pouring from Katsuki. Because if he didn’t he would fall, would fall and wouldn’t have the strength to rise again. But it felt 𝑟𝑖𝑔ℎ𝑡, and he knew what he should but should and could were two very different

things, so all Izuku could do was sit there and let Katsuki kiss him again and again, never taking it further than that but not for the lack of want.

Perhaps he sensed Izuku’s hesitance, or perhaps he had just enough shame to not try and fuck him in the depths of the seminary

archives, but either way Katsuki eventually pulled back, bruised lips smirking when Izuku’s tried to chase after him for more. Instead he just gave him a snake sharp smirk, a promise of later if Izuku decided to follow this path of roses, and walked away. Leaving Izuku desperate

to regain control in the archives, unable to stand for fear of someone seeing the state he was in; at least the desk and books giving him something to hide behind until he had control once again.

Control that had him on his knees in the chapel, praying for strength, for wisdom,

for guidance, for some mysterious accident to befall not the super hot roommate Izuku just 𝑘𝑛𝑒𝑤 was waiting for him, but perhaps to the room itself, forcing them to live separately for at least a few days while he got his heart and mind back in alignment. His dick was a lost

cause, he knew that, but the rest of him he could rededicate to the Lord and ensure his path remained stable. There was peace on this path, he was content here, he was sure his calling was to work in the Lord’s name.

And yet, when he opened the door to their shared room, the conviction he had prayed back into himself disappeared at the sight of Katsuki shirtless, because 𝑓𝑢𝑐𝑘 𝑡ℎ𝑜𝑠𝑒 𝑎𝑏𝑠.

Izuku had barely closed the door when he was pinned against it, Katsuki kissing him again,

only this time half dressed and laughing as he encouraged Izuku’s hands to roam, fingertips dusting over the divots he was too scared to press his hand fully against like he wanted to. So instead keeping himself to gentle touches, finger kisses while their mouths were too busy

learning each other to be of much help lower down. Katsuki seemed to have no such reservations, his hands on Izuku's waist, his chest, his thighs, his ass, sinking his fingers into the muscle to pull him close. Mouth hot and wet on his throat when Izuku pulled back to breathe,

one large hand twisted in his curls to tilt his head enough to give Katsuki access to his pulse.

"Leave with me," Katsuki murmured into Izuku's ear when he finally paused, giving him a moment to think. "I was already gonna jump ship; this shit ain't for me.

So come with me, Izuku."

Izuku froze, eyes wide, breath stuttering in his lungs as he stared at Katsuki, pulling back as much as the door would let him. "You're leaving," he asked, confused and surprisingly hurt. Though he turned away from that pain, digging through the

thoughts to latch onto a random one he could see as safe to ask. "You don't believe in the Lord?"

"Oh, I believe in the bastard alright," Katsuki said, lips pulled into sharp smirk. "I just don't think the fucker deserves to be worshiped like you." And before Izuku could think,

could question, could do anything Katsuki was on his knees, Izuku’s oversized shirt pushed up to just under his pecs, popping the buttons and drawing down the zipper of his pants with his mouth, tonguing at his stomach and biting into the meat of his hip, eyes blown and hooded as

he gazed up. “Let me convince you to come with me,” Katsuki said against his skin, kitten licks over the mark he had made.

“Fuck, 𝐺𝑜𝑑 𝑦𝑒𝑠,” was all Izuku could whisper. Part of him wanted to say more, the lectures and sermons on lust and temptation swirling in his mind;

telling him to stay strong, to resist, that this was his personal Judaean Desert, but his mind was fogging too quick to latch onto any of them, the denial swept away by the pleasure and sheer need for the man so willingly bending for him. Even if he could have come up with

something, anything to say in that moment, his mind went blank as Katsuki took him into his mouth and 𝑠𝑢𝑐𝑘𝑒𝑑, wet and burning hot and overwhelming to his system that not even an hour ago had never been kissed,

had only known his own hand and in comparison that was 𝑛𝑜𝑡ℎ𝑖𝑛𝑔. And when by pure instinct alone his hips bucked, pushing another inch past Katsuki's lips, and Katsuki 𝑚𝑜𝑎𝑛𝑒𝑑?

Izuku was gone. Gone and lost as he willing fell forward and twisted his fingers into Katsuki's too soft for how it looked hair, hips stuttering in an unsteady rhythm as Katsuki expertly sucked and licked and toyed with him, taking everything he could give and adding more, hands

on Izuku's ass just happily pulling him forward, closer, encouraging him to fuck into Katsuki's mouth with a slap that had the muscle jiggling and Izuku almost cumming down his throat. Only by biting into and almost through his lip did he manage to hold,

unsure if letting go would be appreciated, would be polite, his pace slowing as he allowed the mystery of blowjob etiquette to cut through the need.

As if sensing his hesitation Katsuki pulled away, mouthing at the tip, down the vein on the side, kissing his hip before standing

to kiss Izuku himself, his lips salty with pre that should have been disgusting but that had Izuku twitching, trying to get more of the taste out of Katsuki’s mouth and from his tongue. Pulling away, his shirt was pulled over his head, dropped to the floor,

Katsuki’s pants joining Izuku’s as he stepped from them, leaving them both bare and panting, hard and red and leaking.

“Bed, ‘Zuku,” Katsuki demanded, turning himself to rifle through the little drawer in the desk that made up one of the few pieces of furniture in their too

small room. Izuku obeyed, nervous but wanting as Katsuki smirked, hand pulling out a bottle he recognized but that made him flush, because for that to be here, in the seminary, in their 𝑟𝑜𝑜𝑚, meant Katsuki had been doing 𝑡ℎ𝑖𝑛𝑔𝑠 that Izuku himself had denied, if just for

the propriety. Proprietary Izuku quickly lost as Katsuki crawled onto the bed, smile sharp as he raised the bottle of lube, settling himself easily between Izuku’s spread legs. “Last chance, baby,” Katsuki purred, leaning forward to kiss him,

quick pecks that Izuku eagerly returned.

“I want Kacchan,” was all he could think to say, thoughts of temptation forgotten in lue of continued pleasure, spreading his legs wider, raising his hips and drawing him into a longer, deeper kiss as the bottle clicked open,

as wet fingers circled his rim, teased into him, forcing a mewl as Katsuki stroked inside of him where no one else had been, not even himself. One becoming two making him squirm under Katsuki, cock neglected as he was stretched and Katsuki’s mouth moved from Izuku’s own to his

neck, kissing at his pulse, nipping down the arch as he found and pressed on the spot that left Izuku breathless, mind blanking out and quiet for the first time since Katsuki had kissed him, unable to do more but soundlessly move his lips and his hips as he chased that

feeling again. A feeling Katsuki gave him, coming back to that spot again and again as he hooked one of Izuku’s legs over his shoulder, his third finger a squeeze but the sting quickly forgotten with another stroke inside of him.

𝐹𝑢𝑐𝑘 he was going to come just on Katsuki’s fingers, cock untouched, making Izuku flush and whine at the thought.

“Come on baby, hands and knees for me,” Katsuki finally said, pulling his fingers from Izuku’s ass, leaving him empty and wanting. “It’ll be easier for your

first time that way.” His hand was steading as Izuku rolled, arms shaking as he raised himself into the requested position for Katsuki. “Good boy,” Katsuki whispered somewhere behind him, lips pressed to the skin behind his ear, warmth along his back as a large hand took his hip,

helping to angle him, just right. The distinctive sound of Katsuki’s wet hand on his dick, slicking himself up, before Izuku felt the warm head press against his hole.

“I’ve got you,” Katsuki whispered to him, the gentle pressure slowly increasing, his lips following the path of

Izuku’s freckles across his shoulders and down his back, and in that moment Izuku could believe him, that he was a being that deserved to be worshiped, something entirely holy in Katsuki’s eyes worthy of the prayers being whispered into his skin. He turned his head and let

Katsuki capture his lips as the head of his cock popped in, drinking in each other’s moans as Katsuki slowly slid home, inch by inch pushed into his ass with the roll of his hips as Izuku struggled to adjust to the feeling of being so fucking 𝑓𝑢𝑙𝑙,

of the stretch and the burn, perhaps the burn he had always been promised and if so one he would gladly accept the snake for.

Katsuki stopped when his hips pressed hard against Izuku’s ass, chest laid out along the length of his back, kisses peppering the back of his neck while

his hands stroked his side in soothing waves, trying to bleed out the tension still there. A difficult task - it was hard to relax with a monster of a dick in your ass, but slowly Izuku accomplished it, head hanging forward to give Katsuki more access to his neck as he enjoyed

being stuffed and surrounded and pet.

“You’re muttering, nerd,” Katsuki said against his shoulder, his lips curling into a smirk as he slowly pulled his hips back, whatever Izuku had been saying cut off and lost to the air at the feeling. Strong hands moved from his sides to

his hips, tightening, fingers digging into the muscle and little bit of fat he found there to hold Izuku still as just the tip of his dick was left in, a strange emptiness that had Izuku squirming for something, 𝑎𝑛𝑦𝑡ℎ𝑖𝑛𝑔 to return to put out the coiled heat

in his stomach. “Let’s see if I can’t finally fuck you quiet.”

The snap of his hips forced out a cry and Izuku knew he wouldn’t last long. Everything was too hot, throbbing and tight and ready to release the moment he was touched, or perhaps even without one of their hands

between his legs, because Katsuki’s dick in his ass felt far too good and too much and just too everything, beyond what he had ever imagined in the depths of the night the few times he had allowed his mind to wander and wonder. Bites on his neck, his head turned to accept the wet

kisses, Izuku knew he was still muttering every time their mouths parted, still begging as he rocked back to accept everything Katsuki gave him because how could he not, that cord inside was ready to break as he 𝑐𝑙𝑒𝑛𝑐ℎ𝑒𝑑-

And 𝑠𝑐𝑟𝑒𝑎𝑚𝑒𝑑 as his release was cut off, something cold hard beaded strange wrapping tight around the base of his cock, sending him bucking back against Katsuki who never seemed to stop moving, his hand tight and cruel as he tortured Izuku with this new

punishment he didn’t know he had earned.

“You keep calling for God,” Katsuki purred into his ear, licking at the tears spilled down Izuku’s cheeks, his voice loud enough to be heard over Izuku’s whimpers and pleas even though it was barely louder than a whimper.

“‘𝐺𝑜𝑑, ℎ𝑎𝑟𝑑𝑒𝑟,’” Katsuki quoted, pitching his voice up as he drove his hips in hard, whatever Izuku had been about to beg for cut off in his throat. “‘𝐹𝑢𝑐𝑘, 𝑝𝑙𝑒𝑎𝑠𝑒, 𝐺𝑜𝑑, 𝑓𝑎𝑠𝑡𝑒𝑟,’” he teased again, never letting go of whatever cruel contraption he had

between Izuku’s legs even as he picked up speed, grunting as Izuku clenched around him again and again as he kept hitting that spot that made him go blank, that whited out his vision and had him squirming and desperate.

“God’s not the one fucking you, so you can come when you’re calling for 𝑚𝑒.”

Izuku wasn’t sure what he said or how he plead, only that he was, that ‘Kacchan’ fell from his lips like a chant, a prayer, the holiest word he could think of in that moment, anything to chase that

peak that he’d been shown and ripped away from, that Katsuki kept pushing and pushing him towards even knowing it was a sisyphean task, that he would never reach the top and fall unless it was by his hand and his allowance alone. He begged and cried and prayed and when whatever

was wrapped around his dick loosened, his face turned towards Katsuki’s and his back arched so he could be fucked and fully kissed Izuku allowed it, noises muffled as he finally spilled over Katsuki’s hand when he took him and stroked once, twice,

everything too much and too sensitive to wait.

He was vaguely aware of the warm wetness that spread inside of him as Katsuki came as well, his hips only kept up by the desperate grasp his lover had on them as he chased his own release, Izuku unable to hold himself up as he sunk

into his daze. He could feel as Katsuki lowered him down to the mattress, a heavy warmth pressed against his back, Katsuki’s arms wrapped tight around his waist to hold them close together as they just laid there and breathed. Breathed and cuddled and rested in the silence that

enveloped them, existing within that moment of just them two that was heavy with what they had done.

“Did I convince you,” Katsuki asked, voice uncharastically quiet. “Will you leave with me?”

Izuku rolled in his arms, mouth open to respond, but paused as he felt something dig

into his thigh. Reaching down, shifting through the twisted blankets to find the lumpy strand, Izuku pulled it out and held it out, immediately dropping it as he smacked Katsuki before hiding his face in his pillow, ignoring his bedmate’s laughter.

He wasn’t expecting to find his 𝑟𝑜𝑠𝑎𝑟𝑦 in bed with him, covered in his own spend, warm to the touch from being wrapped around his dick.

“It was the first thing I grabbed,” Katsuki chuckled, leaning over the kiss the back of his shoulders, down his spine, nipping at the

cheek of his ass. Izuku just looked over his shoulder and glared, his blush deepening as Katsuki spread his cheeks, watching intently as a drip of cum slid from him, down his taint, Katsuki darting forward and catching it with his tongue before it reached the sheets below him,

Izuku jolting at the feeling of Katsuki’s mouth on his balls. He quickly swatted him away, forcing his wavering glare back on as Katsuki just smirked. “I’ll wash it, ‘Zuku, so don’t be mad.”

Izuku was a lot of things, but he wasn’t a liar, so he couldn’t even lie to himself

that he was still angry when Katsuki pouted, shifting back so he was back at the top of the too small for both of them bed, his arm raised in the offer and hope for cuddles. After a long moment Izuku just sighed and shifted into his arms, letting that warmth envelope him once

again, nuzzling his face into Katsuki’s neck and breathing in the smell of the man he could, perhaps, be in love with. The man he wanted, at least, was willing to accept as more important than the path he had been so sure was the one he would walk,

because Izuku was sure he would follow him.

He would leave with him, would leave this little piece of peace and follow him willingly into the unknown, and trust that whatever path they ended up on together would be the right one.

𝐴𝑓𝑡𝑒𝑟 Katsuki washed his rosary, of course.

You know, sometimes you get a thought and it doesn't go away, and in fact taps into your religious trauma and reminds you of how you were going to become a nun when you were 14 because you thought that was the only way you could get out of marrying a man. And then you got

to college, got a girlfriend, got over the religious trauma and became happy with your lesbianism, and now at 28 you're happy and gay with your gay house and gay family and gay dog and write gay porn. A pretty good glow up, if you ask me.
