Izuku tapped his foot nervously, his emerald eyes flickering from the clock hanging on the wall to the front door, rolling his bottom lip between his teeth as he anxiously waited for Katsuki to get home. The Omega knew the blonde didn't want to go out or do anything special, he even decided to go to work today - even though he wasn't scheduled - but the greenette was stubborn, and he wasn't taking no for an answer! Not when it came to his mate, at least. The Alpha deserved only the best, and he'd be lying if he said he wasn't looking forward to giving him his present.

His heart was hammering in his chest, his face turning red as his eyes focused on the bottle of champagne on the table, and the bouquet of red roses with corny, red paper with pink hearts on it around the stem. That was only the first part of his gift to the notoriously cocky male, shifting uncomfortably at the thought. The present itself didn't make him uncomfortable, it was the lacy undergarments he had underneath, the thought making him flush more. "This is stupid, " He mumbled softly, hiding his face in his hands. "He's going to think it's dumb... "

His Alpha had always had amazing stamina, the blonde could go at least eight rounds before he began to feel tired, but Izuku wasn't as lucky. The Omega could hardly survive three rounds, before his body started to feel hypersensitive and he was on the brink of passing out from exhaustion. The greenette always tried his best to please the Alpha, but no matter how hard he tried, he just couldn't stay awake whenever they had sex. He loved the man dearly, they were mates, after all, but his stamina was little to nothing. The blonde was always grumpy afterwards, as he was almost always still horny after they mated, but he never held it against his freckled mate. He couldn't control it, he just got tired easily, especially with the Alpha milking him dry with each orgasm.

Izuku loved being fucked by the spikey haired male, though. Maybe he couldn't stay awake on his own, but with a little help... The sound of keys jingling outside the door pulled him from his thoughts, the curly haired man standing and quickly smoothing out his clothes with a nervous sigh, before giving a small, shy smile to him as he walked over to greet the much taller male. Katsuki wrapped his arm around his mates' waist as he closed the door, pulling him close to his chest as he planted a sweet kiss on the top of his head, "Hey, baby, " The Alpha said, smiling down at the tiny Omega.

"Hey, honey, " Izuku leaned into him, placing his hands against his chest. "How was work? " He asked, nuzzling into him with a low, satisfied purr.

"Eh, same old, same old. Had another damn assistant quit.. " He said, grinning sheepishly as he let himself chuckle.

Izuku giggled, "Again? Kacchan, that's the third time this week! "

Katsuki rolled his eyes with a small laugh, pulling the Omega over to the couch and pulling him into his lap. "S'not my fault, " He spoke, twirling a curl between his fingers before his eyes landed on the Champaign and roses. "What's all this, baby boy? " The man asked, giving a warm smile to his mate.

"Mm, wanted to surprise you.. " Izuku spoke, nervously looking up to meet his crimson gaze. Emerald orbs met warm, scarlet eyes, his face flushing softly as the Alpha carded his fingers through his unruly curls.

"Sweetheart, you know you didn't have to, " The blonde chuckled, placing his large palm over his Omegas' freckled cheek. "It's sweet, though. Thank you, baby, I love it, " Katsuki kissed him gently, pulling away to stare into his eyes.

"You do..? " Izuku fisted his small hands into the front of the blonde Alphas' suit, watching him with waiting eyes.

"Yes, my sweet baby. I love it, it's so sweet, " The Alpha cooed, leaning down to leave a chaste kiss to the pinkish scar on the boys' scent gland, the claim Katsuki had made on the Omega a few years ago. "Let's open the Champaign, yeah? " The blonde reached over, grabbing the two wine glasses and the alcoholic beverage, proceeding to pour them each a glass. He poured himself a larger portion, as the freckled Omega was bit of a lightweight, and handed the greenette his glass, wrapping a hand around his waist and placing the wine glass to his lips, taking a sip of the Champaign.

"The roses are cute, baby boy, " Katsuki kissed his forehead, his thumb rubbing gently at his hip. "Did you get them from your moms' flower shop down town? " The Alpha asked, taking another sip, receiving a shy nod. "You went all the way there just for me? " The blonde asked with a cheeky smile, earning yet another nod. "Honey, you didn't have to do all that for me, sweetie, " Katsuki said, nuzzling into him.

Izuku bit his lip, leaning over to place his wine glass on the coffee table, before doing the same with the blondes' glass and taking his hands in his own. The greenette stared nervously at his rough, calloused hands, his small thumb rubbing at his mates' hand. "Katsuki, " The Omega said softly, looking up with anxious eyes.

"Yes, baby? " Katsuki asked, worry covering his sharp features. "Is something wrong? "

He took a deep breath, "It's your birthday, and... " The Omega chewed at the inside of his cheek, gulping. "I wanted to do something.... Special.... For you.. " The greenette's voice broke, though he mentally cursed himself. He was as nervous as can be, nonetheless, though, he released the blondes' hands, fingers slowly drifting to his shirt, slowly undoing the buttons one by one. The Alphas' breath hitched in his throat as he watched the Omega unbutton the white shirt he was wearing, bits of orange and black coming into view. "I wanted to give you something you wouldn't expect, something that... I'm not even sure if I'll be able to handle.." With the shirt completely undone, the Alpha could clearly see the lingerie set he had on underneath, his cock hardening at the sight.

His crimson red eyes raked over his body, blood rushing South as he continued to ogle at the tiny Omega. He could only see the top, as the green eyed male still wore his tight skinny jeans, but the design made him want to throw him down onto the couch and take him right then and there. The bra was see through, his nipples swollen and perky from the fabric rubbing against them. The top was just big enough to cover his small chest, being black with a bright orange pattern going across the fabric. A little red bow was in the middle, the Alphas' hands reaching out and grazing over his skin. "God, baby, I-" The man swallowed hard, his knot already begining to swell at the sight. For a moment he thought he might cum right then and there.

"D-daddy, " Izuku muttered slowly shimmying out of his jeans, before taking his spot back in his mates' lap. "D-do you like it..? " He asked, the blonde staring at him silently, his hands finding the greenette's hips. The bottoms were a thin pair of panties, more specifically, a thong. Katsuki's shaft was rapidly getting harder, his eyes staring at the sheer panties on awe, his eyes darkened with lust. The thong was a lot like the bra, black with orange patterns, a little bow right where his little cocklette was.

A low growl fell past his lips, his lips folding up in a snarl as he swiftly shifted their positions, slamming the Omega down onto the couch. "Such a slutty little outfit, baby. Did you get dressed up just for me? " The male smirked, growls of arousal falling past his lips.

"Y-yes, Alpha, " Izuku shivered, "I-i... Bought... Something else, too.. " The Omega looked away, only for the Alpha to place a calloused finger under his chin, forcing the green haired male to look him in the eyes.

"Now what would that be, darling? " He asked, his fangs poking out from his lips.

"E-endurance booster..... " He mumbled, closing his eyes in embarrassment. He knew his face had to be bright red by now, and he didn't want to see the look of disgust in his Alphas' eyes, or hear the harsh words that were sure to come. Though, it never came. Instead, a large hand caressed his cheek, the mans' thumb padding at his lips.

"Baby, " The blonde Alpha cooed softly, his other hand sliding down his side to rest on his waist. "Open your eyes for me, sweet boy, " The scarlet eyed man gently spoke, watching as his Omegas' beautiful, emerald colored orbs opened, his eyes resembling deep pools. He felt as if he could get lost in them, a small grin tugging at his lips. "Good boy," Katsuki's grin grew. "My little Omega did so well trying to please me, doing so much for me on my birthday, " His voice was soft, Izuku's eyes starting to water. The greenette couldn't resist it when he praised him. A long whine sounded from him, small tears falling from his eyes.

"A-alpha! Wanna- Wanna pleasure you! " Izuku whined again, "D-did this f-for you, Daddy, " The green haired boy whimpered out, squealing as he was pulled up, blushing as the blondes' length poked against his entrance.

"You wanna make me feel good, Baby?"

"Y-yes! Wanna... Wanna make y-you feel good... Wanna make you cum.. " Izuku flushed, gasping slightly as the man bucked his hips, the tip of Katsuki's clothed bulge brushing against his slicked hole. The blondes' hands reached behind him, finding his plump rear and kneading the plushness. His experienced hands pulled at his ass, pulling his cheeks apart to rub a finger over his entrance. The Alpha growled lowly at the choked moan that fell past his lips, grabbing at the soaked string and slowly sliding them out of the way, rubbing against his entrance enticingly.

"So wet for me, baby boy, " Izuku mewled at his words, pushing the Alpha down so that he was sitting above him. "Come on, sweetheart, " The man purred out, "Put your pretty lips around my cock, yeah? I want to hear you choke on my dick, baby."

The greenette moaned, slowly crawling up to reach his hands out, tugging at the Alphas' pants. Katsuki pulled at his red tie, loosening it, before tugging it off and tossing it to the floor carelessly. The blonde haired man then threw his blazer off, then pulled the button up shirt off as well. The spikey haired Alpha helped the green eyed male pull his pants off, his dick pressing against it's confines painfully. Before he had time to register what was happening, his little mates' tongue was licking a stripe up the underside of his length, his hands instinctively carding through his hair and tugging at the curls while leaning his head back against the armrest on the couch, groaning.

"Yeah, that's it, baby boy, " The blonde spoke, pulling harder at his unruly locks. Izuku preened at the praise, taking the tip in his warm mouth and sucking. Katsuki moaned lowly, bucking his hips slightly. Taking the hint, the curly haired male started inching down, his warm, tight throat earning a husky growl of approval. The greenette couldn't go down all the way, his Alphas' length too large for him to take in whole. "So good, honey, good job, " The green eyed man purred, his hands massaging the parts he couldn't reach with his mouth. With a hard tug at his curls, the blonde haired male pulled him down farther and thrusted his hips upward into his enticing throat.

The Omega gagged, tears brimming his eyes as the Alpha began to brutally fuck into his mouth, his small hands finding his muscular thighs as a way to ground himself. Izuku choked, his eyes rolling to the back of his head. Katsuki's knot started to swell more, and right before he came, the Alpha pulled his mate off his cock, pulling him up to give him a sloppy, wet kiss. The greenette moaned, rolling his drenched hole over his fully erect, throbbing shaft.

The blonde Alpha broke the kiss to groan, the sensation making him push his tiny mate back down onto the couch, before Izuku whined, squirming around. "A-alpha, nest! " The Omega pleaded out, a low rumble escaping Katsuki's lips once more. With a swift pace, the blonde swept his needy mate in his arms, taking long strides as he walked him to their bedroom, pushing him down into the plush nest the curly haired male had made. Without a second thought, the lustful Alpha pushed him onto his stomach, the greenette sticking his ass up instantly, presenting for him.

The taller of the two crooned softly, pushing the g-string aside as he aligned his shaft with his wet hole. Pushing the tip in had the green haired Omega moaning, mewling and begging for more. Katsuki quickly thrusted roughly, pushing his dick in to the hilt, his hips slapping against the boys' harshly. "A-alpha," He moaned out, the blonde pulling out and slamming back in. "O-ohhhh! Gods, yes, yes! "

Katsuki smirked, his hand trailing up his mates' body, before slipping under the sheer bra, fingers twiddling with the sensitive buds. "Does my baby like that? " He said, starting a brutal pace, his hips snapping forward roughly with each harsh thrust.

"Yes, oh, gods, yes! " He slurred, hands fisting the blankets underneath them. Katsuki suddenly pulled out, drawing a long, needy whine from his mate, before he was switching his husband on his back and thrusting back in. The Alpha leaned down, trailing kisses up his chest, nearly bending him in half, before snapping the lacy bra in half and throwing it across the room. His tongue swirled around the pink bud, earning more throaty moans.

"So good, Baby. Taking my cock so well, can't wait to breed you, to fill you up with my pups. Wanna see you round with my pups, baby boy, " He cooed.

"Y-yes! A-alpha, breed me! Wa-wanna carry your pups! " He screamed out, his Alpha smirking from above him. His eyes trailed down, watching with delight as he bounced deliciously on his cock, his movements perfectly in sync with his rapid thrusts. Izuku reached up, weaving his freckled hands through his mates' spikey locks. "S-so good! " The blonde sped up his pace, his knot swelling and catching on his rim with every thrust.

It wasn't long before he slammed in deeply, his knot locking the two together. The blonde instinctively tried to pull out for another thrust, instead only grinding into him more. The two came, rope after rope filling the greenette as he came all over their chests. The two panted, Izuku staring up at his mate with glossy eyes. "I love you so damn much, Izuku, " He kissed him, rubbing his hips soothingly.

"L-love you, too.. " He murmured, coming down from his high-like orgasm. He could feel the stamina booster already working, making him feel energized, ready to to again. "H-happy birthday, Alpha.. " He smiled up at him, moaning as the Alpha rolled his hips, shifting his length inside and pressing against his g-spot deliciously.

As the blondes' knot deflated, Katsuki pulled out, swiftly trusting back in. "So good for me, baby. Ready to go again, just for me, " The man said, smirking as he pounded into his prostate.

"O-only for you, D-daddy!!" The Omega whined out between blurs of praises for the Alpha.

By time the two had finished, there was cum coating the two, along as the Alphas' seed dripping from the Omegas' abused hole. They had gone nine rounds, and both were utterly exhausted. Katsuki picked his trembling mate up, holding him close to his chest, his arm under his legs as he carried him to their bathroom. Katsuki rubbed the greenette's back soothingly, running a warm bath for them. When the water was hot enough, he set his mate in the tub, sitting behind him and pulling him to his chest. The blonde wrapped his arms around him, kissing the side of his head gently. "Let's get you cleaned up, sweetheart, " The Alpha said softly, grabbing a wash cloth and soap, beginning to wash him.

Izuku tiredly groaned, squealing in surprise as the Alphas' finger entered him. "K-kacchan? "

"Shh, it's alright, baby boy. I'm just getting you clean, honey, "

⋆ ˚｡⋆୨୧˚　˚୨୧⋆｡˚ ⋆

Katsuki dried off him and his small husband, picking him up and walking to their shared bedroom, setting him on the large, plush bed. Izuku yawned, but slowly lifted his arms as the Alpha slid a light pink sweater over his head, and helped him pull on a pair of black boxer briefs. Katsuki simply slid on a pair of boxers, pulling back the comforter and helping his mate in and crawling in beside him. The blonde pulled the Omega to his chest, burying his face in his curls. "Kacchan, " Izuku croaked out through his exhaustion, his throat sore from the rough treatment from earlier.

"Yes, love bug? " He asked, nuzzling closer to his little mate.

"Did you... " The greenette paused, turning over to face the Alpha, looking up at him with tired eyes. He hid his face in his chest, purring softly, before speaking up once again. "Did you like your present, Kacchan? " The greenette asked nervously.

A small chuckle rumbled throughout the room, the green eyed male snuggling closer to his Alpha. "Yes, baby. I loved it, it was so sweet of you, darling, " He cooed, his hands rubbing his back gently. He peppered kisses along his cheeks, trailing down to his bruised lips. "I love you, baby boy. So damn much, " He pressed a chaste kiss to his mouth, pulling away from him with a large smile.

"Mm... Love you, too, Alpha, " Izuku yawned, wrapping his arms around his much larger husband. "Happy birthday," He said, letting his eyes close as he drifted off into slumber.

Katsuki kissed the top of his head before letting him own eyes close, exhaustion finally hitting him fully. "Goodnight, beautiful. "
