“Seriously babe?” the amused alpha asked, holding his hand after they finished the three mile aquarium tour. The omega pouted disappointed because he thought he would see a tiger shark hybrid at the aquarium. Anything is possible right? 

 

“What did you think a tiger shark was?” Mina asked trying not to laugh. She thought he read and watched too much fiction. Kiri thought for a second, slowing down his pace then giggled. 

 

She made sure they didn't bump into anyone or anything as he thought. When the path was clear she turned her gaze onto him. He met her gaze with that innocent smile he always do when he doesn't know what to say. 

 

“You know what you are lucky that you are so cute” she kissed his cheek and he blushed. Mina always knew her mate's elevator did not go to the top but that was one thing she loved about him. 

 

Kiri is a stay at home house husband since he can't keep a job, work hurts his brain. Mina gave him a position unloading supplies since he is so strong for an omega and loved showing off how manly he is. However he would rather be stuck to her than actually work which lowered her productivity. So Kiri stays home with the dog and goldfish.

 

“My feet hurt” he whined, not used to moving around this much. “Come on big boy” 

 

Mina stopped then squatted down. The larger omega climbed on her back wrapping his body around hers. 

 

“I'm hungry” the omega complained not even two minutes later. She mean mugged the people giving them nasty stares as she walked to the car. “What do you have a taste for?” she asked putting the car in gear. 

 

Kiri talked her ear off about the turtle exhibit as they sat in the back corner of the steak house. It seems they will be getting another pet soon. 

 

“Babe, don't talk with your mouth full” she sighed repeating it for who knows how many times. “ m sworry” the omega responded mouth still full of steak.

 

 Mina smiled thinking she should take more days off for dates with her mate. If only her employees' work performance wouldn't decrease. 

 

So outside of his heat or her rut she rarely takes off. The happy himbo omega hates it but he understands that's how he lives his life of luxury. 

 

If you asked him what the most luxurious item in the home was, he would say his stuffed shark filled nest definitely would not be any of the paintings that should be in a museum.

 

🦈🐺

A few days later Mina was hosting a mandatory board meeting watching a boring presentation by her second in command Ochaco when her phone vibrated. 

 

She felt something was wrong with her mate through their link. 

My 🦈 

🦈: Need you

🐺:Whats wrong with my little shark

🦈: Hurt

🐺: Did you bump into some again? 

🦈: My heat - I

🦈: 💬

 

Mina waited a few minutes but didn't get a response. That is when she realized all eyes were on her. 

 

“Ochaco you can finish up. I have to go home.” She forgot her scent blockers. 

 

Everyone knew she was distressed but no one would comment and make it worse.  No one wants to deal with an upset alpha. 

 

“Sure thing boss” was the last thing she heard as she quickly entered the parking lot. 

 

“You can head home early” she told the driver as she slung the door open, shifted the mustang in reverse and rushed home. 

 

Kirishima wasn't answering. Guess the suppressant wasn't working or he wasn't taking them like he was supposed to.

 

She was a mile from home. When she noticed those blue flashing lights in the rearview mirror

 

“Fuck!, don't have time for this” she mumbled getting her license out of her wallet. 

 

“Well I'll let you off with a warning this time Ms. Ashido since ya little mate in heat and all but slow her down” She nodded, giving him a fake smile. 

 

“Just send it in the mail”. The cop gasped in disbelief watching the tail lights for a few seconds as the woman sped off. 

 

“Well that's a loving alpha huh” he chuckled getting into his truck wishing his alpha was more like that. The cop somehow forgot to send the ticket.

 

 🦈🐺

 

“Shh i am here baby” she said in a soothing tone releasing her calming alpha phnemones as she entered the bedroom. 

 

Kiri whined, neglecting the massive stuffed shark he was humping. He flew across the bed clawing at her clothes, his nest falling apart but he didn't care.

 

The omega was a few steps from being completely feral. His hands ran up her pants legs frustrated he wasn't feeling skin as he sat on the edge of the bed. 

 

“Baby let me shower first. I had meetings all day” He growled, taking in a deep breath holding on to her tighter. 

 

“Ok , ok” she said out loud thinking he definitely was not going to let her shower. Seconds later buttons were flying everywhere as he ripped her dress shirt maintaining eye contact the entire time. 

 

“Baby I know you horny but you can't keep destroying my $100 shirts” 

 

She was glad he didn't rip her $60 dollar bra. She would've been more upset. Good bras are hard to find when you have big boobs. 

 

He looked down ashamed then whimpered thinking he was in trouble. His sex crazed brain could not process that her tone was normal. Her long fingers went under his chin lifting his head making him look into her eyes.

 

“I'm not upset, ” she said with a smile as she unzipped her pants with her free hand.

 

 He blinked a few times and nodded, drool slipping out his mouth as her scent got stronger. His hands went to her hips massaging them before he shredded her pants and panties. He was in a hurry to get to her pussy. 

 

“Dam baby, you want it that bad?” she smirked as she undid her bra.She sighed contently at being able to be free.

 

He watched her boobs running a hand up to cup and play with them as his nose nudged her crotch inhaling her scent. Who needs oxygen anyway. He licked and sucked on her wet pussy lips loving her moans. 

 

He moved his hands to her hips letting her hard nipples rest. He slipped her tongue in her tight hole lapping up her juices as her hands went into his hair. She thought she needed to help him dye it again. He refused to go to a salon; it was their tradition since high school. 

 

He attacked her clit sucking and tugging on it, making her bend slightly stopping her thoughts.  He held her hips sturdy pulling off her clit with a pop licking his lips before licking up and down her lips. 

 

She moaned and groaned overstimulated. His grip was strong, she couldn't move nor talk just tug on his hair and take his skilled tongue.

 

She humped his face, mouth open sound no longer coming out as she felt her massive tentaclit uncurl. She sighed in relief knowing her sensitivity would decrease since it was now out.

 

He gagged and pulled off wiping his leaking eyes. He sucked and licked her lips before tongue fucking her. He wrapped his hand around her tentaclit jacking it off slowly as the tip wrapped around his pinky.

 

He closed his eyes as his hand slid down his body. He touched his tiny dick jacking it for a few seconds before sticking three fingers in his soaking wet cunt. 

 

Soon her tentaclit found its way back in his mouth. “No, look into my eyes while im fuckin you” He looked up at her. She was beautiful.

 

 Her lips were swollen because she kept biting them. Her tits were bouncing with how fast her hips were moving fucking his face well throat at the moment. He had to remember to breathe through his nose. 

 

“Good boy” she praised him as she filled his throat with her come. She pushed him back on the bed and he scooted up.

 

 Seconds later she had his legs scissored between his grinding their pussies together as her tentaclit jerked his small cock off. Their nipples rubbed together.. 

 

“Aaa F-fuck” the omega took in a deep breath. “Right there!” he moaned as she rocked her hips faster, sucking on his mark between moans. 

 

“Fuck me Alpha” he pleaded scooting up a bit until he felt the tentaclit near his hole. 

 

They both gasped as her tentaclit entered his tight hole. She set a fast but steady pace fucking him just like he love it. 

 

“Don't stop” he pleaded “you're almost there alpha” he groaned his legs wrapped tightly around her waist. She fucked him slow and deep sucking on his scent gland once again tasting how turned on he is. 

 

“Want you to fuck me preganat” he whispered in her ear moving his hips fucking her back. 

 

“Fuck baby I am” she groaned out fucking him harder feeling his tiny dick twitch as his pussy gripped her tentaclit tighter. 

 

“Aaahhh f-fuck… Yes” he gasped feeling her knot form. He whined trying to escape and get closer at the same time as her knot forced its way in stretching him to the point it burned. 

 

He groaned and stilled as she whispered sweet praises in his ear as she slowed her pace.She bit his scent gland. Her tentaclit got firmer as she filled him with come. 

 His back arched as his broken moans echoed around the room, his claws marking her back up making her hiss.

 

His tiny dick pulsed as it dumped its useless come. The room suddenly felt hot as she tried to catch their breath. 

 

The omega whined from overstimulation as the tentaclit in him lost it firmness and started wiggling inside his thoughly fucked hole. 

 

"I know baby" she whispered kissing his cheek wishing she could control it.

She readjusted them on their side to get more comfortable then rested her hands on his stomach 

 

🦈🐺

The alpha came home with flowers and Kiri's favorite meal. She noticed he has been a bit down the last month . She wondered if it was because he was pregnant or something else but she wouldn't push him on the issue. He will talk when he is ready. 

 

The house was quiet which was unusual. She placed the items on the counter taking a sunflower out of the bouquet.

 

She found him in the bedroom naked in the mirror poking at his bump which wasn't that noticeable at this point.However, Kiri felt he was fat and unattractive. He knew it was the hormones but it didn't make it easier.

 

Mina sighed as everything clicked. Kiri turned as the air changed, his alpha frustration evident. 

 

She walked in the space between him and the mirror. She would show him how much she loved him and how beautiful he was by worshiping every inch of his body. 

 

“My little shark is so beautiful” she said as she presented him with the flower. She dropped to her knees when he accepted it, he wiped tears with his free hand. 

 

“but I-” she tsked. “No buts Kiri, i'm serious”  She ran her hands up and down his swollen legs kissing them gently. 

 

“The most beautiful omega i've ever met” she said as she guided him to the bed once his legs started getting weak. 

 

Once seated on the edge of the bed she got on her knees then massaged and kissed his feet until he sighed contently. She took her time kissing and massaging every part of his body except his vagina which made his arousal increase. 

 

He whined and begged as his inner omega took over pleading for sex. She laughed spreading his legs. Sex wasnt the plan but how could she deny him when he was soo beautiful and carrying her pups.

 

She licked long stripes up his lips before licking the tip of his tiny dick. He moaned groaned and rocked his hips

 

When she sucked his tiny cock and inserted two fingers inside him curling them he saw stars. He jerked and moaned. 

 

“Soo good alpha” he bit his lip, his sharp teeth making it bleed slightly. 

 

Mina's eyes met his and he smiled “mm ka” he stumbled out. She hummed the vibrations sending him over the edge.

 

 He bucked his hips fuckin her face and riding her fingers as he filled her mouth falling back on the bed breathing hard moaning her name over and over. 

 

She pulled off his tiny cock with a pop. She kissed him as his hand tried to reach for her crotch. She stopped him. 

 

“I'm fine baby, I want you satisfied” the alpha said in her no argument tone. The omega groaned as he watched her walk in the bathroom. 

 

10 minutes later they were in the tub. Kiri back to her as she gently cleaned up. She whispered praises and and everything she loved about him in his ear the entire time. 

 

Soon the omega was content and asleep. The alpha gently got out making sure he didn't fall. She threw a towel over her shoulder after drying. She gently got him out and dried. She then laid him in bed and quickly joined him. 

 

“I love you” the barely awake omega whispered. “And I love you all more,” the alpha said, cuddling him and rubbing his bump. 

 

“Good night beautiful” the alpha whispered in his ear then kissed his cheek. 

 

🦈🐺

The alpha woke up to one of the omega hands in her boxers playing with her tentaclit. 

 

“Oh my god” he moaned as he used his other hand to finger himself. 

 

She was used to it since it has happened almost every day since month 5 arrived. 

 

“Well good morning” she said arching her back as the omega hand slid down her lips and two fingers entered her hole. 

 

She ran her hand over his bump pausing for a moment to turn her upper body to the side so she could catch his swollen sensitive nipples.

 

“Ahh” he fingered both of them faster as her free hand jerked her tentaclit off. 

 

She hadn't been this horny in awhile. Watching the omega alternate between desperately fingering himself and jerking his small dick was so hot

 

 “Alpha. smell good” the pheromone drunk omega whispered as he climbed on top of her wobbling slightly. 

 

“Whoa” she said grabbing his hips. “Cant have you hurting our twins” 

 

“Mm sooo good” he moaned out once he was finally seated feeling stuffed. 

 

The alpha sighed, sitting up minutes later knowing that Kiri just wanted to be filled since he made no effort to ride her or beg her to fuck him. 

 

He wrapped his limbs around her as she slowly got up and made her way to the kitchen. 

 

She walked around the kitchen making pancakes and sausage as if her pregnant taller mate wasn't cockwarming her. He moaned and groaned every time her tentaclit wiggled around in him exploring his tight walls. 

 

Once she was finished she sat at the table but he refused to get off her to eat properly as usual. 

 

So she fed herself then lifted the fork. He turned his head as she lifted the fork up to feed him. 

 

“Mm better than sex” he moaned chewing loudly. The alpha chuckled. “As if you would know the difference” 

 

He ate most of his meals while being full of her which made her getting to the office almost impossible. 

 

To her surprise the company productivity levels didn't drastically change and working from home isn't so bad.
