Work Text:
Fingers dug into his sides, tongues dancing across his nipples and down the length of his small omegan cock before it was engulfed in wet heat. Izuku groaned, his eyes closing as his head rested on the chest of one of his mates. He had been awoken earlier than normal by two of them, both needing to go to the agency for a few hours before their ruts started and his heat started and neither had wanted to miss the chance of tasting him before leaving the house.
"Fucking delicious." Oboro growled, his tongue thrusting deep within his ass, saliva mixing with the greenette's slick and pooling into a mess below them on the bed. Hizashi hovered above him, his mouth and his talented tongue with its piercing smack dab in the middle playing with the tip, moaned; a bit of quirk vibrating across flesh.
Izuku moaned, "Alphas. Alphas please!" He begged them, his hands reaching down to grip both blue and yellow strands. Before he could, his wrists were grabbed and pulled away, held in one strong grip above his head by his third alpha.
Shouta chuckled, "Hmmm. I know you weren't thinking about touching, Kitten. I don't believe we gave permission for you to touch yet." His hot breath ghosted across Izuku's neck, a warm, wet tongue dipping out to lap at Izuku's scent gland.
Izuku whimpered, the coil in his gut tightening. "Oh there it is." he heard Oboro laugh, 3 fingers now inside his ass along with the man's tongue. He squirmed but the fingers holding his hips tightened, pinning him further.
"Please, please alphas. Need- need to cum! Please let me cum!" He begged, shaking his head side to side as tears began to fall from need.
Oboro hummed, glancing up at the other two before pumping faster, making sure to hit Izuku's prostate every time while Hizashi chuckled, "Go ahead, Songbird. Cum for us." He swallowed Izuku's cock again, using his quirk once more and causing the green haired omega to blow, slick and cum squirting out hard as he screamed, throwing himself up from the force.
Hizashi helped Oboro up, one headed to the bathroom and the other to the kitchen where they returned with a washcloth and a bottle of water. Hizashi was gentle, carefully cleaning Izuku off before picking the smaller man up and gently laying him on the other side of the bed, pulling off the blanket that held most of the mess they had just made while Oboro helped the greenette drink the water. "Slowly, Raincloud." He cooed, capping the bottle when Izuku had had enough.
Izuku closed his eyes, grumbling happily when both men kissed his forehead, ignoring how the two of them spoke quietly to Shouta before leaving. He felt the bed dip behind him, Shouta's strong arm wrapping around his waist to pull his smaller body back into his chest. "Tired, Kitten?" He asked.
The greenette nodded, smiling softly. "Mhm." He hummed. He was used to being woken early by his alphas whenever they were horny; he'd done the same to them several times in the past as well, but he'd gotten home late from the agency the night before after having closed a case later than normal and had found the three already in bed asleep.
"Sorry Kitten. What time did you get home?" Shouta apologized.
Izuku sighed, rolling over to face the dark-haired alpha. He opened his eyes, looking up at the man. "I walked in the door at about 1am. The Kinko case closed late."
Shouta's brow furrowed, "Why in the world did it close that late? I thought you finished the paperwork for that before Zashi and Boro's patrol ended."
Green eyes closed before sighing. "Officer Jino decided to hand off his paperwork to Fumiko. When told the paperwork gets turned into me, he refused stating that 'an omega doesn't need to see such sordid details' and that it was better left to the betas to deal with. Then he walked out. I had to then get a hold of Jino's boss at the station, get him and Officer Jino to my office, which took a while because Jino decided to not answer his radio or cell phone for his 2-hour break before I finally got to rip him a new one. All while doing the paperwork properly, getting all the signatures in proper working order and filing it with the courts." He groaned as he sat up, shaking his curls. "By the time I left the agency, the trains weren't running. I had to wait for Shiko to order a car for me which took another 45 minutes after none of you answered your phones."
The alpha grimaced. "I'm sorry Zu. I didn't realize you were going to have such trouble, or I would have stopped by the Agency after patrol instead of coming straight home. Or at least stayed awake until you did come home." He kissed Izuku's forehead. "Please forgive me? Forgive us?"
Izuku rolled his eyes, smiling softly. "I wasn't mad to begin with. You guys have been running yourselves ragged trying to get everything ready to prepare for all of us to be out for our shares. How could I be angry that you were all exhausted?"
Shouta smiled one of his rare smiles, the ones that only his mates got in the privacy of their home. "We don't deserve you, kitten." He pulled the greenette closer, laying them both back down. "Come on, love. Let's get some more sleep before your heat starts."
________________
Izuku woke to silence. His stomach growled and he frowned, looking over at his still sleeping alpha. Shouta was just as blank faced in his sleep as he was when he was teaching and Izuku had a hard time not giggling at the look. He gently tossed the covers, easing himself out of the bed. He didn't bother with clothes, having a mate that worked at night meant having a house with all the best light blocking window treatments meaning no one would be able to see him strutting around bare assed while he ate something simple.
He ate a quick bowl of cereal, not wanting to eat something too heavy or make too much noise when a beep sounded from the laundry room and Izuku realized that Hizashi or Oboro must have put the blanket from earlier in to be washed. He padded over, grabbing it out and moaned at the warmed that radiated from the fabric.
Izuku folded the blanket, knowing that if he put it back on the bed it would need to be washed again anyways so it was better to just fold it and put it aside for after their heat and ruts were over but as he bent down to put it on the basket of folded laundry, he felt two strong hands grip his hips.
"Mmmm, omega."
He groaned, his own nose telling him that Shouta's rut had started, his slick already starting to drip from between his ass cheeks. "Did you have a good nap, Alpha?" He asked, rubbing his ass against his dark-haired alpha's rock-hard cock.
Shouta growled, his large hand gripping green curls and turning him to bend the smaller man over the arm of the couch. Izuku could feel his other hand dip between his cheeks, fingering his hole, the squelch of slick loud in the otherwise silent space.
Izuku wiggled, "Please alpha. Come on. Need you." He begged, already breathless as he felt his own heat begin to take hold of him.
Izuku squealed as his mate slammed into him, filling him in one solid stroke. His own cock was rammed against the arm of the couch, pinned against the smooth fabric, but he didn't care.
His ass was dripping with slick, making his mate's cock squelch with every pull and drag. "Gonna fucking breed you. Such a good omega, taking me so well." He heard the man say. A shift on the couch in front of him made him look up, finding another of his mates grinning down at him.
"He's right. You are our perfect omega." Oboro’s words caused another flood, the fabric below him soaked with his juices.
"Damn, ain't this a sight." Izuku turned to find their last mate kicking off his shoes, hand already deep in his pants as he stared at the scene.
"Zashiiiiii...." Izuku whined, one hand forcing Oboro closer until the alpha was within reach. "Please. Need you. All of you."
He missed the way Oboro and Hizashi grinned, exchanging looks with Shouta who was stuffing their mate full. He was getting bred and they weren't stopping till he was carrying their pups.
Oboro shifted closer, coming just within reach of Izuku's mouth, his hand going to the green curls. "Come on, Raincloud." He pressed lightly down on the greenette's head, bringing him closer and Izuku let him, drawing his alpha's cock into his mouth. He sucked on it, not getting very much of it as Shouta kept pounding into his ass but it seemed to be enough for the bluenette who leaned back and moaned happily as he ran his fingers through the curls. "Fuck, yes."
His hand was then grabbed and Izuku's eyes looked over to find Hizashi bringing it closer to his own cock, helping Izuku rub his fingers along the piercings he loved so much. He clenched around Shouta, making the man groan as his hips stuttered, "Fuck, Kitten. Just like that." Shouta growled.
It was difficult to keep his attention on all three of them but he managed it with their help and direction, each of them using their own hands to seek their pleasure until Shouta covered his back with his body, slamming deep into him as his knot expanded, locking them together. "Fucking hell!" Shouta yelled before his fangs connected inside Izuku's scent gland, just over his original mating mark.
At the same time, Hizashi came, his hot cum splattering all over the greenette's hand while Oboro filled Izuku's mouth, taking care not to knot past his teeth. Their cycles abated, cooling for a moment with them having orgasmed but each of them knew it was nowhere near over.
Sure enough, after only an hour, they were back at it again, except this time they were playing monkey in the middle and Izuku was the monkey in the middle of Oboro and Hizashi who were sharing his ass while Shouta was fucking his throat.
Izuku moaned, sending the vibrations down Shouta's cock. He loved having his alphas fucking him stupid, but he really loved the stretch his heat allowed his ass to have, making it super easy for more than one of them to share his hole at the same time.
They had started a rhythm that had bounced him hard and fast on each cock, one going in while the other drew out and vice versa, never faltering and never failing to hit his prostate with each thrust. Oboro, who was on the mattress below them, had been using his mouth to play with Izuku's nipples and Hizashi had been nipping at and kissing his neck the whole time, creating even more pleasure and sensitivity while he swallowed around his third alpha who had been standing next to the bed.
"Fuck, gonna cum. Gonna knot, knot you. Pup you!" Oboro growled, his arms tightening around Izuku's torso. He could feel Hizashi getting close too, the blonde alpha tensing and his pace faltering even as his fingers dug into the greenette's hips.
Izuku pressed his tongue against the underside of Shouta's cock, running the muscle along the shaft until the man groaned and stilled, his cock head buried deep down Izuku's throat as he came, making the greenette swallow every drop. His hands pulled on green curls, the bite of pain sending sparks through Izuku, forcing his own orgasm in which he clenched down around the two cocks still pounding his ass, crying out his pleasure even with Shouta's cock still in his throat.
Feeling the tightness of their omega's ass sent the last two through their own orgasms, both slamming home as their knots filled and stretched, pressing together to further stretch and fill the space as they came, their seed searing a path through the omega's womb.
Izuku collapsed, his eyes closed as his breath changed slowly from ragged to slow and steady, indicating that he had fallen asleep, much to the amusement of the three alphas. "We should get some sleep while we can as well. There's no telling how long this will last."
Shouta shockingly woke first, looking at his phone for the time when he realized how dark it was in their room only to jolt awake when he saw how long they had slept. He turned, finding the other two alphas still asleep with Oboro curled gently around Izuku.
"Hizashi. Zashi, wake up." He urged, shaking the blonde. Hizashi groaned, sitting up as he wiped his eyes of sleep. "Huh? What's wrong? Is Zuku ok?"
Shouta rolled his eyes. "I think so? I mean we've slept for the last 7 hours so either our ruts and his heat were super short or..." He trailed off as Hizashi's eyes widened and his head whipped to the side to stare at their omega who was purring happily as he cuddled their other mate.
"Did we do it? Did we pup him?" Hizashi whispered. Shouta shrugged, "We can find out in the morning. It's too late to do anything now and for all we know it could just be a long lull between waves."
Hizashi nodded, letting out a long breath before laying back down. "Right, right. Ok. Sleep. Sure." He spoke to himself. Shouta snorted, pulling the blonde into his arms. "Goodnight Zashi. Love you." Hizashi yawned, wiggling softly, "Good night Sho. Love you too." They both fell back to sleep, dreaming of the tapping of little feet as pups ran around their home.
Izuku woke the next morning to find himself completely alone in bed, each of his alphas somewhere in the house. He tensed, confused for a minute before realizing that his heat shouldn't be over yet. "Pups." He whispered, laying a hand over his stomach. He had to be pupped. His inner omega purred at the knowledge and Izuku grinned before climbing out of bed.
He could vaguely smell a whiff of milky tones that brushed along with his normal scent, and he giggled before padding over to the bathroom. He needed a shower and knowing his three alphas, they were probably going to want to take him to Chiyo to make sure he was indeed pupped before they told anyone else. Which meant that Izuku needed to be clean of sweat and cum and any traces of sex before seeing the woman he thought of as his grandmother.
What Izuku wasn't counting on was being in the shower for only a few minutes before he was joined by Oboro, the tall alpha wrapping his arms around the short omega who purred as he leaned into the man's arms. "The others went to pick up breakfast as well as Chiyo and Nedzu." Oboro offered, grabbing Izuku's favorite scented soap before starting to wash the omega's back.
Izuku nodded, "Sounds good. I'm nervous but I am pretty sure she'll agree that I'm pregnant. I caught a whiff of milk when I smelled my own scent earlier." Oboro chuckled, "Yeah, I did too when I woke to the other two whispering early this morning."
They finished showering quickly, Oboro taking care to dry the greenette fully before picking out some of Izuku's post-heat clothes that he knew the other man liked so much, making it into the living room and sitting down to watch tv before the others even arrived, heralding their entry with loud voices and exasperated comments.
And of course, Chiyo being herself, only had to work on Izuku for a few minutes before she smiled and nodded, confirming everyone's thoughts.
Izuku and his alphas were expecting.
