Im like a whole day late but its ok

Today was Deku's birthday, this was the day he officially turned eighteen, and Katsuki knew he had the perfect birthday present for his boyfriend.

It was pretty thought out- a masters plan. Nothing too much or overwhelming, just something that Deku always wanted to do since they'd started dating.

He was going to let Deku top him.

The two had been together since they both were sixteen and never once had Katsuki let Deku top.

Of course he had other things to give him besides his ass. . . but that's not the point. Well, it kind of was . . . but anyways, Katsuki's ass was going the best gift ever.

For almost three years Katsuki would hear him beg to not be the bitch for at least one night. And tonight was going to be that night. If it hurt, Katsuki swore he was never going do that shit again.

As of right now, Katsuki was wearing his favorite pink apron in the kitchen of his own apartment he shared with his lover. He and Deku bought it a week after Katsuki turned eighteen, which was only a few months ago. They moved out because of the fact that they had sex nearly every day or night and they didn't want to traumatize their friends with . . the sounds.

The leftover vanilla cake batter was left in the bowl and Katsuki swiped the side with his finger then licked off the sweet, white, creamy substance.

Katsuki hummed in delight. It had the right amount of sweetness just how his Deku liked it.

He glanced down at his phone, finger still in his mouth as he checked the time. It was almost seven, Deku should've been home by now or at least on his way.

Earlier, Katsuki had asked for Uraraka and Todoroki to keep him busy today by buying him things he wanted for his birthday. Though whatever they got him wasn't going to top what Katsuki had in store.

About two weeks ago, Katsuki had bought a stack of ten CAMPUS notebooks for his nerdy boyfriend and wrapped it around with a red ribbon then topped it with an equally red bow. Deku's favorite color was red so he just went with that.

He also got him a limited edition All Might figurine that came out last week. Katsuki chuckled, imaging Deku's reaction when he saw it. He was still such a fanboy nerd.

It wasn't long before the cake was done baking. Katsuki opened the oven to see a perfectly risen vanilla cake. The top slightly golden, beautiful, and the aroma was absolutely delicious. Grabbing his to-match-apron pink mittens from the counter, he pulled them on then bent over to pull out his masterpiece. He swore he just kept getting better every time. The chef used his heel to kick the oven closed then placed the hot pan on the table.

The cake had to cool off before he removed the dessert from its pan and layered it with frosting otherwise it would surely fall apart.

Though he was busy in the kitchen, he couldn't help that his thoughts kept going to the bedroom and what would happen. Not that he would admit it though, but he was honestly scared.

Scared for his asshole.

But he couldn't back down now. He wouldn't back down. That would take a major hit to his ego if his boyfriend could take it up the ass like a pro and he bitched out like a pussy.

The cake took about a good thirty minutes to finally cool down and Katsuki had already iced It. To finish it off, he opened the 18 candle pack and place the lime green candle in the center. Perfect.

Then all of a sudden he heard a ping. He checked his phone and seen that had gotten a text message from Todoroki saying that he and Uraraka just dropped Deku off in front of their apartment and he was on his way up.

Shit.

Katsuki took a few deep breaths to steady his suddenly racing heart.

Okay, okay, Katsuki, you know what to do. Calm down you bitch.

Katsuki untied his apron and hung it on a hook on the wall near the refrigerator.

It was never mentioned that he was wearing something underneath.

Only thing that he had on was a red ribbon that was tied around his slim waist and bowed in the back, right above his ass.

Time to loose his ass virginity.

Katsuki hurried to the bedroom and studied everything he prepared earlier. He lit very vanilla scented candle, smoothed out any rumples in the peach sheets, and looked in the full bodied mirror on the closet door to make sure the large ruby bow was still perfect. It was.

He then climbed onto the bed and like he always told Deku to do; he pressed his face down onto a pillow and held his ass up in the air for Deku to see as soon as he walks through that bedroom door.

.

Izuku fished for his keys when he got to his apartment and unlocked the door. He enjoyed his time with his friends- he actually had a few bags of All Might shirts and underwear. But he missed his boyfriend. He knew Kacchan had something for him when he got back, why else would he tell him to  spend  the day shopping? He just didn't know what this gift was and needless to say, he was curious to find out. Surprise party? No. Kacchan didn't do those. Taking him out to eat? Maybe. Maybe not.

He opened the door to be hit with the sweet smell of freshly baked goods.

Vanilla.

He immediately recognized the smell.

He glanced towards the kitchen to see a cake on the table. Izuku smiled and his heart warmed. But where was Kacchan? Izuku expected him too yell happy birthday by the front door.

He peeked in the living room,  thinking that he'd see him propped up on the couch. But no.

Perhaps he was in their bedroom?

Izuku slowly made his way down the hall, gliding his fingers crossed the wall.

He noticed a dim light shining from under their bedroom door.

His face scrunched up in confusion. Izuku placed his hand on the door knob and turned it.

What he saw then registered, immediately took his breath away following by his dick getting hard, and he flushed severely.

Kacchan ass was up, legs spread as he was looking over his shoulder at him, his hole was- everything was on full display. And the bow- oh my god, the bow.

The lighting was beautiful everything looked beautiful, the room was showered with the heavenly vanilla scented candles he just noticed.

There was a heavy dusting of pink across Kacchan's cheeks, and he pouted. "H-happy Birthday, Deku. ."

The fact that he stuttered went straight to Izuku's cock.

This. . this was happening? Or was it a dream? Was Kacchan really offering his self to Izuku like that-

"A-are you going to keep mumbling and staring at my ass from all the way over there or are you going to come over here and fuck me?" Seems like weather he was a bottom or top he still had his attitude.

"Kacchan. ."

Izuku pushed the door closed behind him and peeled off his shirt, tossing it anywhere. He couldn't take his eyes off of Katsuki's ass that was topped with that bow. He's never seen his boyfriend put himself in this vulnerable position before. He felt the urge to devour him. To destroy that pink hole that was presented to him. Is this how Kacchan felt whenever Izuku bottomed for him?

Well damn, he must have a strong ass hold on Katsuki then.

Izuku turned to the nightstand, without taking his eyes off his present. He opened the drawer and blindly took out a bottle of birthday cake flavored lube. Funny; they got this earlier this year for Katsuki's birthday, good thing the bottle wasn't done yet.

"Okay, Kacchan," he squirted some onto his fore and middle finger. And he brought it to Katsuki's hole. He wasn't a pro, but he learned what to do by taking mental notes of his times with Kacchan doing it to him.

"C'mon, hurry up! You're taking so long." Katsuki impatiently complained and backed up on his fingers. "You should know how to do this already, as many times as I-"

"Y-yeah, but you never let me experience it for myself," Izuku was so flushed right now he thought he was going to melt.  "I've never did this before, I-i'm a little nervous."

Katsuki held his eye for a second then sighed. This was his first time taking charge- Katsuki didn't want to seem like he was controlling him. "Okay," he simply said, letting his face fall back down onto the pillow. "Do whatever you want." His  voice was muffled.

Izuku let out a breath and, push his fingers inside his warmth, in return, got a whimper from him. Kacchan lifted his head from the pillow he was now hugging tightly with one hand and looked over his shoulder again. "W-wait," tears prickled in the corner of his eyes when he brought his hand to wrap around Izuku's wrist.

All at once, Izuku stopped what he was doing and turned his full attention back on his boyfriend, he hoped he didn't hurt his precious Kacchan.

"D-does it hurt?" He made a quick glance from Izuku's crotch then back at him, obviously indicating that he meant his cock.

He almost forgotten that not only was this his first time getting ready to top, but this was also Kacchan's first time giving 'that' up. He must be scared.

Izuku blushed, a smiled followed after. He wanted Katsuki to feel secure, to know how good it felt when he was on the receiving end, "Kacchan. . baby, if you're worried, don't be." Slowly, Izuku caressed Katsuki's spine and kissed it. "It may hurt just a little bit, but I swear I'll take care of you, I promise."

Katsuki shivered at the feeling of Deku's lips upon his lower back, his scarred fingers inside of him. He didn't know why, but those words made him feel safe.

"Fine, fine, fine, you damn nerd," he was blushing like an idiot. "just hurry up and shove your dick inside me already-"

Katsuki jumped when Izuku's fingers brushed a very, very sensitive area. "Fuck!" He moaned into the pillow.

Seems like the nerd had learned something.

Katsuki heard the sound of Izuku undoing his belt. He glanced over his shoulder.

Of course Izuku's cock wasn't as big as Katsuki's but it was compatible in length and girth. Maybe only an inch lesser?

"Okay, I'm going in." Izuku's cock was resting on the crack of his ass and he dragged it down. Kacchan whined.

Once Izuku was lined up he took Katsuki's request to shove it in into good use. Oh how long Izuku's been waiting for this. He gripped each side of Katsuki's hips and pressed the mushroom head if his hard cock into the somewhat loose ring of muscles.

Izuku's eyes rolled to the back of his head, goddamn, he was so hot and tight.

Immediately Katsuki keened and hissed at the stretch of his virgin asshole.

Katsuki's back arched. Shit, it hurt. 

Pulling out, pushing in.

Pulling out, pushing in.

Pulling out, pushing in.

It felt so good and it hurt so bad.

Within a few seconds, Izuku was slamming his pelvis against Katsuki's ass cheeks over and over again, hitting his deepest most sensitive parts that have never been touched before. Kacchan soon gotten used to the stretch and was now focusing on the feeling of Izuku's cock sliding back and forth against his lubed up wet walls.

The bow atop his ass bounced with every thrust.

"Deku," he choked out. Saliva was soaking and darkening a small area of the peach pillow that was under his mouth. "Shit, shit, shit," he moaned as Izuku jabbed at his prostate several times.

Since it was his first time getting it up the ass, he came quickly. His body shook with the intense prostate orgasm.

He and Izuku noticed it only a second after. Katsuki flushed even more -if possible- with embarrassment. He didn't normally come first. He glared back at Izuku daring him to say something or make fun of him.

Katsuki's expression suddenly switched. His eyes rolled back into his head and his tongue stuck out like a feverish dog.

Izuku's hips hammered into Katsuki's back side with even more force, knowing that he would obviously be over-stimulated after coming. Since this might be his last time topping he wanted to fuck him as hard as he could.

~~~

Some time later, Izuku pulled out.

He watched as his cum dripped out of Katsuki's abused hole. It was raw, red and puffy. Obviously sore.

"My fucking asshole hurts. ." Katsuki breathed out tiredly. He was exhausted. It was way past his bedtime. He glanced at the window. And it was already morning. His back hurt like a motherfucker.

Izuku knew exactly how Katsuki felt, after all, he had power bottomed nearly every night. He placed a kissed on Katsuki's red hole.

Katsuki seemed too tired to notice but he did moan out Deku's name, so that must've meant he did.

Izuku had collapsed on top of Katsuki. He was also tired as shit. He rolled off to lay beside and face his exhausted boyfriend.

"Happen birthday, Deku. ."

"Oh, Kacchan," Izuku brushed a strand of Katsuki's blond hair from his sweaty forehead. "I love you so much,"

"I love you, too," he smiled, his red eyes drooped with sleepiness.

"I also have something else I wanted to give you."

Izuku wrapped an arm around Katsuki's waist, pulling him close enough so both so of their noses were touching. "We're not in a rush, you can show me it later," Izuku kissed Katsuki's nose. "Go to sleep, baby."

As if those were magic words, Katsuki immediately fell asleep in Izuku's arms.
