Thanks to the rock-paper-scissors sorting, Yuria and I ended up riding together. We climbed into a figure-eight tube designed for the torrent slide, sitting one in front of the other.
Between Yuria's "special service" and the physical contact, my blood had already completed its own plummet to my groin, but the real water slider was only just beginning.
"Actually, I'm glad you're sitting in front, Ryouta. If you were behind me, I know you’d be staring a hole through my body the entire time."
"……Well, I’m not going to deny that."
"See? Off-the-shoulder swimsuits are really prone to slipping if things get wild, so I was seriously worried. Too bad for you, Ryouta."
As she spoke, Yuria used those famous thick thighs of hers to softly squeeze my back from behind.
The sensation of that flesh—which was just as soft and yielding as Airi’s chest—was absolutely irresistible.
Dammit… if the human body were designed with a face on the shoulder blades, I could have been sandwiched by Yuria’s thighs all day.
"Next group, go ahead!"
The lifeguard at the start position pulled back the gate holding our tube, and we were suddenly swept away by the current.
Finally, an event that should have been the most foreign to a loner like me—a water slider with a girl—had begun.
The descent was gentle at first, but looking further ahead, I could see a massive drop. It had a terrifying angle; we were clearly going to accelerate all at once from there.
"Whoa! It’s getting fast, Ryouta!"
"O-Oh… yeah, no kidding."
"Hm? What’s wrong? Are you scared?"
"I-I’m not scared!"
Yuria was taunting me loudly from behind, so I twisted around to snap back at her, feeling a surge of irritation.
Damn her… she’s really pushing my buttons.
It wasn't just her words, either. Since a moment ago, she had been sticking those long, thick bare legs of hers out from under my armpits, pressing her thighs firmly against me.
(God... the feeling of those massive, meaty thighs is starting to make me feel "excited" in my own lower regions, too.)
While I was desperately trying to keep my blood from sliding toward my lap, the tube suddenly plunged into the rapids!
The moment we hit the torrent zone, my hair stood on end. The spray of water hitting my face actually stung.
"……! Wha—Yu-Yuria! This is way too fast!! Yuria! Are you okay?!"
"Wheee! This feels so refreshing!"
"How is this refreshing?! It’s—it’s too fast! Yuria!"
"Honestly, Ryouta. Calling my name even at a time like this… you really are hopeless without me."
Yuria seemed perfectly composed, muttering something to herself, but I was being tossed around so much I felt like I was going to bite my tongue. I didn't even have the breath to open my mouth.
"Seriously? Well, looking after Ryouta is my job anyway, so I guess it’s fine. But if I’m really that important to you, then maybe soon—"
"Hey! How do you have the breath to talk to yourself at this speed?!"
Wait! This wasn't the time for witty retorts! The end of the slide where we’d crash into the pool was looming right in front of us!
Bwahhh! This thing is too fast! I'm being washed away! Help me, Yuria! Pffft—! Rui! Airi! Tanakaaaaa!
In the instant I became like a certain character being swept down a river, we crashed into the landing pool, sending up a massive wall of water.
"……What a hell of a ride."
It was so intense that a pathetic sound escaped my throat.
I had been so focused on Yuria’s thighs that I’d completely forgotten the person in front takes the wind and water head-on. It had been genuinely scary.
Now that the slide was over, we floated leisurely along a gentle current toward the tube collection area.
"Phew…… was everything okay? Yuria……?"
Wait. What was this sensation?
Something was pressing against my back……
Yuria’s legs should have been under my armpits until just now, but they had been replaced by her arms.
(Is she…… is Yuria hugging me from behind?)
When I tried to turn around, she stopped me with a sharp, "Don’t."
"S-Sorry, Ryouta. Just don’t look this way for a second."
"Eh? I mean, okay, but…… why are you clinging to me?"
"…………"
"C-Could it be that suspension bridge effect?! Yuria, have you finally fallen for me?!"
"No! Whether I like you or not is a separate issue! I-It’s not that!"
"Then what is it?"
"My! My swimsuit! It got pulled off by the force of when we hit the pool! It’s floating somewhere behind us!"
Wait, what?
Her swimsuit came off?!
……Which meant these two voluminous, soft things I felt against my back were…… Yuria’s!
"Whoaaaa!! Yuria’s bare breasts are right against my back!"
"Shut up, idiot!"
Yuria headbutted my back while still clinging to me.
"I-I can’t hide them with just my arms, and they might slip out, and I think the top will drift over here in a minute, so…… just lend me your back."
"Eh, a-ah, sure."
Yuria’s chest…… on my…… back?!
I rejoiced at the fact that a lucky pervert development straight out of a rom-com manga was actually happening.
And since they were bare…… could it be that the sensations I felt against my back were…… Yuria’s "points"?!
This thrilling water slider hadn't just provided thick thighs; it had delivered a busty surprise—with cherries on top.
I felt like I was eating the most expensive parfait in the world.
"Hey, Ryouta…… stop squirming around so much."
"O-Oh……"
For such a lucky pervert moment…… no, a lucky super-pervert moment to happen. I found myself wishing the swimsuit would never drift over for the rest of my life.
"Ah, here it comes."
The top drifted back to us before we even reached the collection area. Yuria quickly grabbed it and pulled it back on.
I didn't get to see her exposed from the front, but the experience I'd just had was even more exhilarating.
In a slightly awkward silence, we reached the end of the line, climbed out, and waited for the other three to slide down.
"W-Well, that was a fun ride!"
I said something generic to break the tension, but my mind was stuck on the feeling of her breasts.
To think I’d become so conscious of something other than her thighs…… the power of skin-to-skin contact was terrifying.
"More importantly, Ryouta…… did you feel disappointed after feeling my chest against your back?"
"D-Disappointed? No, I was incredibly excited! I mean, they aren’t as huge as Airi’s, but I definitely realized you’re well-endowed."
"I-I’m happy to be praised for that…… but,"
Yuria looked up at me with a shy, slightly mischievous smile.
"I…… actually have a bit of a complex about my 'points' being kind of big. I mean, as long as I’m wearing a swimsuit, no one will ever see them, so it shouldn't matter, but…… you felt them just now, didn't you?"
"Eh! N-No, on the contrary…… I,"
"Hm? What?"
"I prefer them that way! Or rather, it’s just incredibly hot!"
"Eh……"
When I spoke honestly, Yuria looked confused for a split second before her expression softened back into a grin.
"Heh. Just as I thought, you really are a weird pervert, Ryouta."
"Urgh……"
I felt like we were having an incredibly lewd conversation. This was bad…… my body was reacting again.
"Well, the secrets I share with you just increased by one."
"That secret is way too perverted for my heart……"
"Really? But with our relationship, sharing secrets like that isn't so bad, is it? A little naughty secret between us."
Sharing lewd secrets…… what a perfect relationship we have.
