For Katsuki’s birthday, his pack surprised him with a trip to a seaside resort. The alpha could only think of how hot Deku would look in his little swimsuits on the beach, splashing around in the waves. And all the new places they’d be able to fool around in. Fuck, he was horny.
What he didn’t know was that they weren’t going alone. The whole damn pack was tagging along.
Ponytail had the hookup, reserving the entire resort just for them. They wouldn’t have to worry about anyone recognizing them or taking pictures (which would’ve been more ideal if he and Izuku were there alone). Ears was providing the music, catering the playlist mostly to Katsuki’s taste and accommodating others by choosing songs that he at least tolerated. And the rest? They were just gonna be idiots.
He was sure they all probably had their parts to play. Even Mind Fuck. His job was probably just to keep Dunce Face in line, which Katsuki believed would be the most difficult one.
The whole way there, everyone was in good spirits, but Izuku seemed to be the most excited person of the group. His nerd kept going on and on about the history of the place and all its amenities. Apparently it was a small, secluded place with a private beach that All Might had frequented so much the owners decided to erect a statue in his honor. Of course he would know that.
All Katsuki wanted to do was lie around in the sun, evening out the tan lines from his costume while he watched his mate run around in skimpy clothes. Maybe swim in the ocean. But what he was really looking forward to was that couple’s massage his friends had booked for him. Both he and Izuku needed it.

The first official day of their vacation started at the pool. He had to admit, it looked pretty damn luxurious. The weather was perfect, the sun high in the sky with a slight breeze keeping the temperatures down. The pool was huge and lined with dark, smooth stones.
On the sides there were comfortable lounge chairs that sat in the water on a shallow shelf, umbrellas resting behind to offer shade. The side closest to the hotel was lined with outdoor furniture and fire pits surrounding a small outdoor bar. The other side was an unobstructed view of the beach.
This was gonna be a good trip.

Fucking count on Denki to be a bad influence.
Katsuki was laying on one of the chairs in the pool, Izuku draped on top of him. He was rubbing circles into the omega’s back, occasionally playing with the strings on his orange bikini. They both took in the view, watching as Mina and Eijiro were playing around in the water. Momo sat on the shelf nearby, making toys and throwing them out into the water for them to play with while Kyoka massaged sunblock into her shoulders. Hanta was relaxing in the chair next to them, Shoto curled up next to him. He had just come out of his heat and was super sensitive, so they kept to themselves. Half n’ Half was probably pregnant now, his scent already smelling subtly milky.
Katsuki couldn’t help but feel a little jealous. He had been wanting to talk to Izuku about starting a family, but fuck , the nerd was kicking ass on the hero charts and he loved to see it. The last thing he wanted to do was jeopardize his dreams, but Katsuki was having dreams about his omega wearing one of his shirts, round with his pups and absolutely glowing.
Izuku looked up at him with a quizzical gaze, most likely sensing the smoky shift in his scent that usually came with arousal. He tried to distract himself from those damning thoughts by avoiding those viridian eyes staring right through him, only to notice something rather important.
There was no sign of Denki.
“You seen Troll hair and Pikachu anywhere?” He asked Izuku. He didn’t feel like moving to look around, but he couldn’t help but feel that chaos was imminent.
“Hmm” Izuku stalled whatever cogs were turning in his head to look around. “Nope!”
But speak of the devil…
“Zuku!!!” The electric blonde cried. He was carrying two very large, very pink drinks in his hands and grabbing the attention of his omega. “You gotta try this!”
Izuku hesitantly took one of the drinks, and despite not being a fan of alcohol, sipped on it. His eyes grew wide in amazement. “Soooo good!”
Hitoshi came up behind Katsuki, handing him an old fashioned. He sipped his own drink as he sat down on the chaise next to him. “Gotta be careful with those, Denks, there’s three different kinds of liquor in there and a ton of sugar.”
Denki seemed to not be listening as he went around the pool, dragging Izuku along as he socialized with the rest of the pack.

There was a reason Izuku usually stayed away from alcoholic drinks, and now everyone was going to witness it.
After one drink, the nerd was playful. Izuku chugged the rest of his drink and jumped into the water without a care about who he splashed. He looked like he was having fun with the others, throwing around a ball and fighting over who got to float on the inflatable swan. Of course his omega always won. Even under the influence he was powerful as fuck.
After two, he started to let loose. He, Denki and Mina were dancing to the music they asked Kyoka to play for them. Mina was enjoying teaching Izuku some more provocative moves that he’d normally be too nervous to attempt, but the omega seemed up to the challenge and looked good doing it. Sometimes they would drag Ei and Hanta whenever the beat was right, and it looked like they were all having a good time. Meanwhile, he had Hitoshi and Sho on each side, content in observing the spectacle from afar.
After three, Izuku was a bit… unpredictable. At this point, it seemed like the group had moved on to selfie time. Mina took it upon herself to be the designated photographer as they all moved around the different picturesque backgrounds in the pool area, making sure everyone had the best lighting and poses. Sounds tame enough. That is, until Denki picked the drinks back up, pushing one into Izuku’s hands, and they started taking pictures with them.
At the nerd’s insistence, they decided to pose with the statue of All Might. Deku had his arm wrapped around Statue Might’s shoulders, raising his glass to the camera. Pikachu on the other hand, had his wrapped around the statue’s waist, holding his glass up to Statue Might’s lips making it look like he was drinking. Katsuki couldn’t help but chuckle a bit because it was funny. Well, it was up until the idiot spilled his drink on Statue Might.
“Oops!” Denki giggled, “Pouring one out for the homies.” the blonde declared as he continued to purposefully spill his drink.
The smile on Izuku’s face dropped and he started tearing up. “But All Might’s not dead!” He cried, arm crackling with a low percentage of One for All and throwing the half-full plastic cup down before running back to Katsuki.
If there was one topic you didn’t touch, it was All Might’s mortality. The nerd had been worrying about his mentor ever since he said he wouldn’t live to see the end of All For One, even though he did.
Izuku cried his eyes out on Katsuki’s chest, leaving a trail of salt water dripping down his abs. The sadness was fleeting though, and he smiled as someone gave him another drink. And after four drinks? Well… Izuku was very flirty.
“Kaaacchaaan” Deku purred, straddling Katsuki’s lap. His swimsuit top was loose and barely covered anything, but he didn’t seem to care.
“What?” He tried to feign indifference, but in reality, he was really liking the scene in front of him.
“Kaaaacchaaaan,” Izuku moaned slightly, grinding down onto Katsuki’s now very interested dick. Since no one was wearing scent patches, Izuku’s jasmine scent was intense and only growing sweeter as he started slicking through his swimsuit.
“Not here, you idiot.” Katsuki’s voice was gruff, he knew his scent was giving himself away, but he didn’t really want Izuku getting him this worked up in front of the idiots, at least not when Izuku was drunk. He could feel all of their eyes on them, trying to hold in their laughter. They seemed to love drunk Izuku, but Katsuki didn’t want to share drunk Izuku.
“Kaaaaaaaaaaacchaaaaaan!”
“What?!” Katsuki asked, grabbing Izuku’s hips to stop him from moving, but he was weak to the feeling of his omega’s firm yet cushiony hips.
“I have needs Kacchan!” Izuku practically screamed and Katsuki had never been so quick covering the idiot’s mouth with his hand.
“I’m pretty sure you need water more than anything, dumbass.” He gave Izuku a water bottle, but the nerd only took a small sip and pouted.
“Kacchan,” Izuku whispered, leaning closer to Katsuki. “Come here.”
He did as his omega requested and leaned in, feeling the other’s warm, boozy breath on the side of his face.
“I need…your cock.” He whispered again, giggling like a child.
Fuck.
Katsuki leaned forward, his lips grazing Izuku’s earlobe before whispering back, “Is that your way of seducing me? Come on, Deku, you gotta do better than that.” He really didn’t though, Katsuki was ready to take him right then and there.
Izuku pulled back. His plump lips settled back into a pout, but Katsuki could tell that he was really thinking about what to say next.
He leaned in again and whispered sensually, suddenly sounding more sober than he had been in hours, “Breed me Alpha.”
Katsuki picked Izuku up and carried him away, not bothering to say anything to anyone in his rush to knot his omega.

That night, the rest of the pack learned that the rooms were not soundproof as they heard Izuku getting railed all night. They chose to move rooms the next day.
And when Izuku’s eyes sparkled as he showed Katsuki a positive pregnancy test a month later, it was the most amazing gift.
Best birthday ever.
