They get washed away by a huge tidal wave

With that, Airi and Jungo go back to their spot and actually start to enjoy their date. Since it's lunch time now, Jungo takes out some food from the cooler that he brought.

"Chanwanmushi again?" Airi pets his cheek. "You never change, do you?"

"If you want me to make something else, you can ask." Jungo retorts.

"I wouldn't mind it every once in awhile." She goes in to kiss his face for being considerate making both of them blush.

"Out of fear you'll punch me, I wanna say you look really sexy in that."

Airi is stunned for a moment wondering what possessed him to say that. "Uh, thanks. You also look really hot with just your swimming trunks on. It's also really nice of you to not have your oversized beanie on too. You should do that more often."

"Is that supposed to be a compliment?"

"At least the first part. You can take the second part however you want."

"Ok" Jungo starts chowing down on the food he made admiring his hot girlfriend in the process.

Turns bright red from all the blushing. "Y-you're not thinking of doing t-t-that to me, right?" Airi says. flustered. "It's not like I'd want to with you or anything."

"I don't know what you mean."

"Y-you know, like the birds and the bees."

"What about birds and bees has to do with us?"

"Urgh, fine, sex! I'm talking about sex!" Airi gets tired of Jungo not understanding.

"Sex? Oh well, I'm a man. I thought that was obvious. And last I checked, you're a woman."

"I don't mean that kind of sex either." She crosses her arms under her boobs in frustration. "Here let me show you" She takes Jungo's hand and sticks a finger out, then she makes a circle with her free hand. "So to demonstrate, this finger is you, and this circle is me. What I mean is, you take this finger and push it through the hole of the circle repeatedly until some sticky stuff comes out. Did you not have sex ed in school or something?"

"Oh I get it now. Well clearly I wasn't thinking of it, since I didn't know what you meant."

"You doofus, hehehe." Airi blushes at his stupidity. She then proceeds to kiss him on the cheek. "I guess, since I asked if you were thinking it, you wouldn't mind doing it if I accepted right?"

"I don't think I would." He goes in to hug his girlfriend, feeling her chest press against his.

"Could've given me a warning." She hugs him back. "Well are we done? There's an ocean behind us we haven't touched."

"Mhm" Jungo stands up and extends his hand to help Airi get up like a gentleman. Airi takes his hand even though she didn't really need his help. They both run off into the water and splash each other a bunch and challenge each other with swimming and underwater breathing as well. Thanks to Jungo's better athleticism, height and lung capacity, he usually beats her. At some points, Airi's top still fucks with her and flings itself off of her boobs, which she fixes whenever she notices. Eventually, their fun gets ruined when a giant tidal wave comes crashing onto the beach.

"Jungo!" Airi cries as she tries to locate Jungo.

"Airi, where are you?" Jungo wades through the water trying to find Airi. The water dissipates finally after about 5 minutes of terrifying waves. "Airi, Airi, if you're ok, say something!" Jungo calls out to Airi.

"Brrrrr, can the water be any more cold? Huh?" Airi hears Jungo calling out to her. "Uh, hey, hello, I'm fine!"

"Ok, ok, great." Looking around. "Uh where are you exactly?"

"Have you tried looking behind you?" Airi snarks.

"O-oh" Jungo turns around and sees his girlfriend then goes to bear hug her.

"Hey hey, don't squeeze me so much!" Airi tries to tell Jungo.

Jungo feels around the back of Airi's body, feeling like there's something missing, his dick seems to think so too. "Hey uh Airi, I don't know how to tell you this....."

"Y-you don't mean.....?" Airi sounds worried. She then tries to feel around the parts of body that are meant to be covered, only to find nothing anywhere. "Dammit!!!! How dare the water take my clothes!!!!" She looks around hoping no one is looking. "Jungo, babe, please go see if you can find my bikini."

"I'll try my best." Jungo lets go of her and turns to the water to see some yellow things floating, so he quickly jumps in the water and swims toward what looks to be his girlfriend's bikini.

Airi goes to sit down on their surprisingly in tact beach blanket covering her privates. "Great, now how do I explain this to any life guard that sees me? This beach doesn't even allow for naked people!"
