There's trees skirted by pools of white snow. When the wind blows, the snowflakes look animated. Snowflakes take to the air in an elegant dance, pirouetting around the tree trunks to their own orchestral rustling. When the wind calms, the dance ends and the snowflakes land to form new pools that look identical to the ones they were previously in before they started to frolic. Pulling his knitted dark red scarf over his mouth, Bakugo strolls through the park and enjoying the weather. The corners of his mouth turn into a faint smile as he shuts his eyes, thinking about his mate's expression when he gets back since his omega has no idea he's coming home early. Katsuki is one of few alphas who were away on a hero mission that was going on for two months, and now he gets to return home just in time for the holidays. Long missions like this one are all part of being a pro hero, and being the number one hero doesn't mean Katsuki can avoid them.
Katsuki quietly opens the front door to his and his mate's penthouse apartment, wanting to keep his presence a surprise for once instead of slamming the door open followed by a loud greeting. Much to Katsuki's surprise, Izuku is vacuuming the living room while singing along to the Christmas music playing from his headphones and the omega occasionally pauses to twerk a little. Izuku doesn’t hear his mate coming home, however when their eyes meet, he yanks the headphones out of his ears and fumbles to shut off the song while his face lights up brighter than a Christmas tree.
“Don't stop on my account, Deku.” Katsuki smirks at his flustered omega and walks over to Izuku, pulling him close and grabbing that plump butt with both hands. “Were you practicing for me?”
“W-Wha-- Kacchan!?” Izuku squeaks in disbelief when he's pulled close, wondering if this is a dream before tearing up happily and throwing his arms around Katsuki's torso before he can realize his actions and burying his face into the taller man's chest. Izuku inhales deeply as he takes in the alpha’s scent, feeling a fuzzy warmth running through him when Katsuki returns the hug with both of those strong arms. “Welcome home.”
“I'm back, Izuku. You're my cute fucking nerd so don't let anyone else see you dance like that.” Katsuki growls possessively as he lifts his mate's chin, leaning down and biting the bond mark that already shows their love.
It takes only seconds for their lips to be less than a few centimeters apart after Izuku let out a faint gasp at being bitten again. Red eyes meet green ones before their lips connect tenderly. The kiss is gentle, but captivating, a mixture of sweet champagne and salty ocean water. Mesmerized lips press together again and again, transporting them to another world. Ragged breathing and dancing tongues bring a fiery heat to the cold city air flowing in from the window. With just the two of them there, reality disappears. Desire igniting the world around them as they sink deeply in a sea of lust and love. It’s a heated, powerful combination that sends passionate waves crashing over them.
The rest of the world becomes engulfed in their lustful burning flames as their kisses grow more urgent; rushed. When their lips finally pull apart, a light breeze flutters over the blue flame extinguishing the desperate heat. Both of their breathing starts coming out in short, desperate gasps. Intensity has washed away as reality slowly returns.
“K-Kacchan, let me put on the surprise I planned first. Please wait for me here.” Izuku manages to say shakily, blushing up to his ears at the reaction he may get as he heads to their bedroom after wiggling out of his mate's arms.
The thing that catches Katsuki's attention immediately is the skin tight orange strapless sports bra, more accurately a piece of fabric that looks painted onto Izuku's pink perky nipples. The straps to the top are flimsy black ribbons and they even create a bow in front of Izuku's muscular chest. Then, Katsuki slowly drags his eyes south slowly before gawking at the black garter belt that has dark green ribbons keeping it tied in place. Behind the garter belt is a lacy red thong, and attached to the belt are black thigh high stockings. The finishing touch to the entire get up is the pair of black stilettos Izuku has on, making him slightly taller but he's still shorter than Katsuki.
“Ground Zero lingerie? Fuck, Deku…” Katsuki inhales sharply at the sight of his omega dressed up just for him in his hero colors. His blood instantly runs south, making his pants incredibly tight.
The ash blonde quickly throws Izuku over his shoulder, heading back upstairs to their master bedroom. Katsuki tosses his mate onto their king sized bed before yanking off his coat followed by his shirt so quickly that Izuku doesn't have time to blink. “Do you know what you're fucking doing to me, Deku? Fuck, I never thought you would dress up like this especially for me.”
“Kacchan, I would do anything for you, but this is for a special occasion.” Izuku responds with a bright smile, caressing up and down Katsuki's chiseled back slowly. “Remember how we talked about having kids before you left? About how badly you wanted a family with me as he made love during my heat?”
“Yeah, of course I fucking remember. Who do you think I am?” Katsuki raises an eyebrow suspiciously as their eyes meet before an incredibly sweet scent hits his nose. This is sweeter than Deku's usual scent.
“Well, the number one hero, Ground Zero is going to be the number one dad in eight more months.” Izuku says happily and smiles from ear to ear as he eagerly waits for the alpha's reaction.
Katsuki blinks in confusion and frowns as the gears in his head suddenly start cranking he tries to process the information. He's far from stupid but the sentence suddenly caught him off guard without warning. His cheeks suddenly heat up when he looks down to find his hands being placed on his mate's stomach. “Wait, fuck… we’re having a-- holy shit you're fucking pregnant!? Shit… we're having a baby, Bunny.”
“Yeah, we're finally having a baby.” Izuku whispers fondly as tears form in his sparkling eyes.
The two of them have been trying to have a baby for the past few months. Now that they finally succeeded, neither Katsuki or Izuku can believe it's actually happening. Izuku looks up at Katsuki with his gleaming eyes before he gets pulled into his mate’s warm embrace. Izuku sinks his face into Katsuki's neck as if to ask him to never let go. He’s so lucky and blessed to have a handsome, strong, slightly devilish man as his mate and husband.
“Izuku, focus on me .” Katsuki’s authoritative alpha voice slips as the blonde tries to get the freckled omega to stop his mind from wandering and he can't help but smirk at the needy whine that escapes Deku’s lips. Clothes quickly become a thing of the past, except the lingerie, before Katsuki sits with his back against the headboard, nearly folding Izuku in half while holding up his hips.
Katsuki smirks as he takes the lip licking sight of the slick glistened hole before gliding his tongue along his mate's entrance. Since they started experimenting with sex in middle school, it's become well known between them that Izuku absolutely melts from Katsuki eating him out. Izuku used to blame it on his omega instincts, but he can openly admit to his mate that he loves the sensation.
“Katsuki…” Hearing his actual name roll off Izuku's tongue effects Katsuki a lot more than it should. Not only is it a rarity, it's arousing especially when said omega is moaning his name and not the nickname that stuck since childhood.
For the umpteenth time in his life after meeting Katsuki, Izuku is genuinely glad that his natural omega instincts allow his body to relax in his arousal which means he doesn't have to wait to feel Katsuki push inside him. Their eyes meet once more when he's rolled onto his back, and it feels like Katsuki’s torturing Izuku with his handsome, lustful grin and heated gaze especially because it's leading to him producing a lot of slick around the alpha's cock. His seductive grin is scorching, completely in tune with the hunger in his eyes along with the almost brutal pace he's setting.
Katsuki barely feels the blunt nails digging into his back as he's drowning in the omega underneath him. Never has he imagined actually claiming and marking his fated omega when they were reunited four years after graduating high school. He's been pushing Izuku away in fear of his own feelings for so many years, but not anymore. Now they're mates and they're going to have a baby in eight more months. The bed underneath them starts to creak and rock from the force of Katsuki’s powerful thrusting. He never holds back with Izuku since the omega is the only one who can handle such powerful love making without any penalty.
Izuku smiles, fucking smiles , once they're both back down to earth after their synchronized orgasms. The smile starts out small, but as it grows, it presses his freckled cheeks up and slowly reveals Izuku's teeth which shine brighter than a perfect pearl necklace. Finally, the smile reaches his eyes, lighting them up, causing them to crinkle at the the corners. In that exact moment, he becomes everything Katsuki ever wanted in life and everything Katsuki could ever need in this lifetime or the next one. There's two words that pop up as the alpha flashes a smile back at his mate: fucking beautiful.
“I'm lucky you chose me as your mate, Kacchan. I don't think I could live without you.” Izuku admits softly with a yawn, resting his cheek on Katsuki's chest as they make themselves comfortable under the covers. “I love you and I can't wait to love our baby, too.”
Deku, I can't properly express how much I fucking love you.
