Chisaki's household,
Nighttime...

Izuku's POV

I stared at the shimmering diamond ring on my ring finger with a smile of bliss. My face slightly tinted with rosey pink shades due to the happiness I felt. I couldn't help but smile all the time.

"Honey... What are you doing?" A familiar monotonous asked me in confusion. I snapped out of my little world, turning to look at the owner of the voice. The smile on my face grew wider. "Oh, nothing." I answered, smiling sweetly at my husband.

Kai tilted his head a little, still puzzled by my meaningful smile. "How are the little ones and Eri?" I asked, breaking the silence between us. "Ah, they are asleep... At last." He heaved a sigh of relief and made his way toward our bed. He sat next to me, eyes fixed on my hourglass figure.

Kai suddenly got closer to my face. He started to sniff on me. "Look at you... Smell so sweet like strawberry." He whispered seductively, voice turning huskier. His muscular arm dangerously slithered around my slender waist. This action of his sent shivers down to my spines.
Kai roughly pushed me laying flat in the bed while he towered over my body. I was trapped by his two strong arms caging me on either sides of my head. We both gazed into each other's eyes deeply, admiring the beauty and loves sparkling in his golden eyes.

A year had passed since Kai returned to my side. Kai and I... Are married for 11 months already. One month after he returned, he wasted no time and proposed me. It was only necessary. We had been waiting for this day for eternity.

We both are officially husband and wife, and proper parents for our four children.

Now, Eri is 11 years old. The triplets will turn four soon enough and then develop their Quirk.

Kai leaned closer to my head and nibbled on my earlobe. His slick tongue licked the shell of my hear in such an arousing way, causing my body to heat up. "K-Kai..." I softly moaned his name, my fingers wandered in the sea of his brown locks.

I could hear Kai groan lowly as his delicate fingers trailed down to my exposed stomach. I was wearing an alluring night gown that would surely made Kai crazy for me. Well, at least that was what my best friend said.

"It works for me and Katsuki! He really loves seeing me in this nightgown!"

Is this a right choice? To wear revealing night gown like this? I have never try on one.

"Mm, sweetheart... You really wanted to tempt me, aren't you? You bad, bad girl..." Kai chuckled darkly, his hot breath brushing my neck. "We just did this before, and you are ready for more? So naughty.." His long fingers made circular motion on my stomach tantalizingly slowly.

I started to squirm under my husband, feeling something growing in my system. I stared at Kai with pleading look. "K-Kai, I..." I couldn't say anything else. Only his name that would leave my mouth. Only him... I was thinking of right now. Nothing else was in my mind.

Kai chuckled again and held my waist. "How about we don't use protection this time...and have another one?" His joke made me blushed in embarrassment. I immediately pushed him away.

"Kai! We already have four kids in our hands!" I said furiously, looking away from Kai pouting. We had decided not to have kids for a few years and focused on raising Eri, Ken, Aiko and Ichiru.

Kai didn't seem to mind my anger. Worse, he laughed it off. "Sorry, honey. But I did this for Ichiru." His words caught my attention. I stopped pouting and turned to my love of life.

"What do you mean?" I asked, curious about his statement. Kai's elbow was against his lap as he rested his chin against his palm. "Ichi told me he wanted a little sister." He said nonchalantly, and my jaw dropped.

Now that he mentioned it... Ichiru had been throwing tantrum much more frequent than before. And he would always ask for the same thing.

"Ichi want liwtle swister!"

"Wh-Why did he want a little sister? Did he tell you?" I questioned my husband, sweat trickled down the side of my face. "Hm... I asked him about that and his answer was..."

I gulped down my saliva, nervously waited for him to continue.

" He said "If Ichi hash liwtle swister, Ai-nee wiwl buwlly her and stop buwlly me"," Kai imitated our youngest son's way of speaking. Compare to his older siblings, he was more late to learn speaking and talking properly. So his pronunciation was a little off.

There he goes again, mimicking Ichiru's pronunciation even after I warned him not to.

I activated One For All at 2% and smacked his shoulder lightly. He hissed, starting to rub his aching spot. "Hey, what is that for?" He asked, now his turn pouting. I snorted -- almost burst out my laughter actually -- when he was acting so childishly like this.

Soooo cute~

I crawled toward my husband and without warning, connected my lips with his. It was only for a few seconds, but the kiss was nice and beautiful.

I parted from Kai, staring into his eyes. Kai suddenly gripped both my wrists and pinned them above my head. "Now, now, dearest, are you trying to seduce me?" A smirk formed on his handsome face. I looked away, embarrassed.

"I-I think..." I answered unsurely. To be honest, I wasn't sure why I did that too.

Kai leaned closer to my neck and kissed my jawline. I tried not to breathe out my soft moans by biting my own bottom lip.

"Let's have some fun, shall we?"

With that, Kai and I continued our long night..

(Don't worry, they use protection since Izuku insists. XD)

Outside their room...

Third Person's POV

Ken stared at his parents teasing each other on the bed in silence, before he slowly walked away from their room. He woke up from his slumber all of a sudden and wanted a hug from Izuku so he could fall asleep again, but seeing them busy, he decided it was best not to enter their room.

Heading to Eri's room, he pushed open the door that wasn't close properly. He headed to Eri's bed, climbing onto it. The little boy patted Eri's head.

Eri stirred in her sleep, slowly opening her red eyes. "E-eh? Ken, why are you here..?" She asked sleepily, rubbing her eyes accompanied by a yawn.

Ken reached out his arms to Eri and opened his palms. "Hugs huggies." He muttered cutely. Eri chuckled at his demand. She gave her little brother a warm hug.

"Why don't you go to Mommy? You always ask for a hug from her, didn't you?" Eri said softly as he stroked Ken's brown locks.

"Mommy and Daddy wrestling on bed."

"Wait, what?"
