Summer vacation has started. That meant beaches! Swimsuits! A tan! The chance to go karaoke with your friends while drinking cold boba milk tea. Ice cream on cones or on sticks as you walk the deserted night beach!

Wait! Don't go away! It is truly summer vacation this time!

Matter of fact: Issei and his wives were on the way to buy them swimsuits. Of course, they already owned swimsuits. But who was to stop them when they wanted to buy new ones? A girl must have a new swimsuit every year you know?

And so, Issei was accompanying them to the department store. Rias had her arm around Issei's right arm while Irina intertwined her fingers around Issei's left hand and clung to his arm. Issei was already used to this and was able to balance himself despite the odd weight.

Issei and Irina were dressed casually. Issei wore a white shirt with "Oppai" written on it in English text and loose jeans. Irina wore pearl white leggings under her caramel colored tunic, she wore a pair of sneakers to accompany them. Rias on the other hand, chose a more summer look with a tube top and breezy skirt complimented by her heels (not too high).

Excitedly, they entered the air-conditioned mall and headed towards the department store, which was designed for the summer. Swimsuits, floaties, and packed snacks were all on a ten percent discount. Cardboard suns with sunglasses hung from the ceiling and spun around. The family of three was greeted by a bubbly saleswoman and were guided to the women's swimsuit section of the store.

Irina was the first to let go of Issei and Rias followed, but not before a quick kiss on his cheek. Irina flew to the bikinis on the hangers, admiring all the colors and designs while Rias took a more laid back approach.

Irina ran to the changing rooms after asking a staff member if she could try on the swimsuits they had to offer. "Psst! Issei," she called out after she changed. "You there?" she stuck her head out of the curtain.

"Yes, I'm here," Issei said. He was seated on the bench adjacent to the changing rooms.

Irina grinned and opened the curtain, exposing herself to Issei. She struck a pose and peace sign. "How do I look?"

"Beautiful."

"You always call me that though," Irina cutely blushed.

"Stunningly beautiful," Issei said. He wiped off his nosebleed with a handkerchief, unable to use his tentacle due to the saleswoman near them.

Irina grinned, her smile shining like the sun. She was dressed in a yellow layered two piece. "Wait, I've got one more."

As Issei waited for Irina to get changed. Rias emerged from the other changing room. If Irina's swimsuit made Issei's nose bleed, Rias' made his jaw drop. She wore a neon blue bikini top that complemented her blue eyes. A blood red sarong with blue, yellow, and orange highlights covered her from the waist down. The sarong was translucent though and Issei could see in between her thighs. Rias did a catwalk towards Issei, her lush leg peeking through the slit of the skirt as she sauntered towards him.

Rias' smile was sultry as she cupped Issei's chin with one hand. The ghost of her touch lingered on Issei as Rias sauntered away. She paused and posed. She raised her arms and hair, giving Issei a view of her back and sideboob. She rolled her hips backwards then disappeared into the curtain. Issei still remembered the way her pink lips curled up into a smile before she hid herself.

"Damn. I love her," Issei muttered to himself. He picked his jaw up from the ground and reattached it. One of the perks of being a monster, he mused to himself.

"Issei!" Irina reappeared from her changing room. Her current swimsuit blew him away. It was a simple one piece and showed much less than her earlier two piece but it looked beautiful on her. The one piece highlighted all of Irina's curves and when she turned around Issei's nose bled even more. Her back was bare.

Irina's face turned red in the silence. "So… how do I look?"

"Drop dead gorgeous."

"O-Oh, really?" Despite being married already and doing all the things that couples do, Irina was still quite shy. A true maiden even if she no longer had her maidenho–

Irina got an idea. She pulled away the bands that usually held her twin tails, letting her long bright brown hair fall. The way her hair fell was like a hime cut, although it was a mess at the moment since it was in a tie.

"Could my wife get any cuter than this?" Issei asked the female salesman.

The saleswoman, sweating from how hot Rias and Irina were, couldn't give a reply.

"Issei!" Irina blushed.

"It feels like someone mixed sexy and cute then presented it to me," Issei said, adding to Irina's embarrassment and joy. He gave her a thumbs up as he wiped away the waterfall of blood from his nose.

Rias, fully clothed, came out of the curtain. She had the swimsuit she picked folded neatly in her arms. "Ara, are you not done yet Irina?"

"I'll just change back! Why are you so fast, Rias?" Irina shut the curtain behind her.

"I only picked one set."

"Aha! You're confident in yourself this time?"

"Of course," Rias smiled smugly.

Irina emerged from the changing room, fully dressed but without her shoes and twin tails. She danced around before sitting with Rias and Issei on the bench.

"So?"

"So?"

" 'So?' " Issei asked, raising his eyebrow.

"Who was sexier?" Rias asked. "Me or Irina?"

Both girls looked in anticipation as Issei closed his eyes in thought.

Irina put on her shoes. Rias, as they waited for Issei's answer, took the hairbands that Irina had and daintily tied up her hair. They were done and Issei was still not yet done deciding.

Rias playfully layed her chin on Irina's shoulder, tickling the younger girl.

"Issei, you know you're not going to get away without judging who is sexier?" Rias said as she dug her chin deeper into Irina's shoulder. The younger tried in vain to push Rias off, all the while holding in her laughter.

"Rias was sexier." Issei finally spoke.

Rias did a fist pump, finally releasing Irina from her clutches. Irina tried her best to look disappointed but couldn't, since her shoulders were still shaking from laughter.

"That's another point for me, Irina," Rias said.

"N-No fair…" Irina moaned when she finally got ahold of herself.

"All is fair in love and war, dear."

Irina pouted and clung to Issei, looking for comfort. Issei smiled in sympathy as he stroked her hair.

"Why don't we get some dinner?" he suggested.

"That's a good idea," Rias said.

"Let's go," Irina said as she dragged her feet.

"Shhh, I still think your outfits were cuter than Rias'," Issei whispered to Irina.

"You really think so?" Irina brightened up.

"Really really."

"You know I can hear you guys?" Rias said.

" "Eep!" "

"You're late," Koneko greeted them as they arrived home.

"You're supposed to be asleep."

"Nya~" Koneko purred. "Buying swimsuits shouldn't take that long."

"We visited a place so…" Irina trailed off.

"Lewd."

Irina blushed. "You're not supposed to know things like that!"

"I'm just a year younger than you, nya~" Koneko smiled smugly.

Yuuma appeared from the elevator. "Ah, welcome back!" she eyed the plastic bags that Issei was carrying. Normally, one wouldn't be able to see through the nearly opaque plastic but being of the supernatural had its perks for eyesight; especially for crows. "Are those swimsuits?" she ran towards the group at the entrance. "I like one too! But–" Yuuma looked sheepish. "I have no money so…"

"Don't worry. I'll treat you," Issei said.

"Issei…" Irina shook her head. Cute girls were Issei's weakness

"I would like to come to, Issei-senpai," Koneko pounced on the good graces that Issei was giving to Yuuma. "I also want a cute swimsuit nya~"

"Sure."

"I love nya~!"

"What is this about swimsuits?" Ravel came down from the staircase.

"Nothing that includes you."

Ravel bristled at the comment of Koneko but said nothing.

"Do you also want a swimsuit?"

Ravel tilted her head cutely in thought. "If it is from you, Issei-sama, then yes."

"Tch-" Koneko clicked her tongue while Ravel grinned haughtily at her.

"We'll go before lunch tomorrow, is that good?"

[Yes!]

And so. Day two of picking swimsuits starts tomorrow~.
