CRASH

A sound so deafening made both the male woke up from a quite peaceful sleep. They stare at each other and shrugs a bit, ready to go back to sleep. They had forgotten they had a pair of twins that they adopted from Iwaizumi and Oikawa, their seniors in college.

Suddenly, Karma's mother senses started tingling. He quickly threw the covers off and got out of bed before running to the living room. There, a little mini Oikawa who they named Haruki was reaching for a UFO on the highest part of the shelf.

Karma basically skidded forward and made a dive, just in time as the three year old slipped from the shelf. The kid fell into his arm making karma sigh in relief, who knew learning volleyball would save a kid's life one day?

Gakushuu was about to go back to sleep when his daddy senses tingle. He did the same thing as his husband and ran towards his office in the house. There, he saw the mini girl version of Oikawa but with black long hair and iwaizumi's dark coloured eyes, reaching for a Godzilla figure. He was about to just sigh in relief and just give it to her, when, a box fell off the shelf.

Gakushuu wasted no time to run and get into position before spiking the box aside before it could hit the child. Ignoring the box, he knelt down and check Akari for any injuries before he smile and gave her the Godzilla figure when it seem that she was okay.

The two twins were really a handful, how Akari would bring home stag beetles while Haruki would want all the alien related things. But one thing always kept the two bonded, Volleyball.

Which was why Karma and Gakushuu was in the backyard with two volleyballs. Karma was a setter and a libero while Gakushuu was a wing Spiker, they were playing alongside their seniors and was now in the national league.

Now, both the male were showing the kids how to toss a ball and receive. Making sure their tosses weren't hard and that the net was set low. Though, sometimes karma would accidentally set it high and Gakushuu instinctively spike it down. Thank God it didn't hit the kids.

The twins, for some reason, were Volleyball geniuses. Iwaizumi and Oikawa would come by frequently to check on them because they never wanted to give their kids away but they just couldn't handle it financial wise and time wise.

"Yoohoo~ Akari, Hakuri!"
Of course, both the kids recognize who their parents really are and didn't mind widening their vocabulary to call all four them 'dad'

"PAPA! DADDY! PAPI AND APPA WERE SHOWING US HOW TO RECEIVE!"
The twins practically shouted out of excitement making the two older male chuckle a bit.

Iwaizumi swept in and picks up the twins in his bara arms, gently nuzzling them. "Is that so? We're you naughty?"

Akari shook her head and grins happily. Oikawa looks at Karma and Gakushuu with a sly grin. "BET WE CAN SHOW THEM HOW TO PLAY BETTER!"

Karma grins, taking it as a challenge. "2 on 2, one set. Let's go." He said as Gakushuu fixes their net to the correct height.

The twins were put down and now they were sitting quietly, happy to watch a set of the game they grew in love with. That, was how all four adults played volleyball until midnight and the twins lectured them in baby language. Although adorable, they were bored and just played with the kids before putting them to bed. The karushuu couple allowing the iwaoi couple to sleep in the guestroom.
