The first set ended with Range and Talc’s victory.

The second set began immediately. Shiori and Chika were forced to take off their pareos and hoodies because it was the rule, and they became subject to lewd stares from the men around them.

"Ohhh, ohhh...!"

"That girl’s boobs are seriously huge..."

"That girl’s legs are so well-shaped and beautiful."

"That girl has a really great figure... It’s amazing."

"Big breasts and a big butt—that’s great."

"Uh... uh... ♡"

"Uh, uhhh... ♡"

With the pareo removed, Shiori’s lower body became more clearly visible. With her hoodie off, Chika’s body—including her M-cup breasts and massive buttocks—became even more clearly visible, revealing their curves and size. The men stared at the two women’s beautiful, erotic bodies with lustful eyes. Shiori and Chika, feeling vulnerable, covered their breasts, buttocks, and crotches with their hands.

"Everyone’s looking at me with such naughty eyes... ♡ I can’t believe I have to keep playing beach volleyball in this kind of environment... ♡"

"Ugh... My boobs and butt are being stared at with naughty eyes... Being looked at like this gives me chills... ♡"

Deep down, however, they were excited by the lewd stares directed at them from all directions.

As the two secretly grew aroused, Range walked over holding a ball, a grin on his face.

"Heh heh... Alright, let’s start the second set. We won the first set, so we’ll serve. Here we go... Here it comes!"

"Ah...! Hmph...!"

"Whoa...!"

With a sly grin, Range delivered the serve that signaled the start of the second set. It flew toward the center of the court. Shiori quickly moved to catch the ball, then Chika tossed it and bounced it into the air.

"Phew... hah!"

Then Shiori made her move. This time, perhaps to avoid another accidental slip, or to make it seem like it was just the wind, she didn’t have Chika hold up her hands as a platform to jump from. Instead, she launched her attack while standing on the sand.

"Yo...!"

"Here we go...!"

"Heh heh... Alright, let’s go for it!"

But because she only threw it while standing, its momentum was slower than a jumping attack. As expected, it was blocked by Range. The ball was then tossed by Talc and bounced back up. Then Range unleashed a jumping attack.

"Ah...! Hyaah...!?"

"Chika...!"

The released ball flew straight toward Chika. Chika instinctively braced herself, but her large breasts got in the way. She couldn’t catch the ball with her hands in time and was hit in the chest again. At that moment, the ball bounced in an unexpected direction. Now that the hoodie that had been restraining her breasts was gone, Chika’s chest bounced and swayed even more violently than before.

"Ohhh! Here it comes!"

"Here comes the boob jiggling!"

"It’s even more intense than before!"

"That’s great, Range!"

"Uh...! ♡ No, no...! ♡"

"Ah, ah...!"

The surrounding men cried out in excitement at the sight of her enormous breasts swaying. Faced with such enthusiasm, Chika screamed, clutching her hands to her trembling breasts out of shame.

Watching her younger sister’s embarrassed expression, Shiori instinctively rushed toward the ball that had been sent flying, dove in, and bounced it upward with her hands.

"Wow! That was a great dive!"

"That one was good too!"

"The part where it rubs against your boobs is the best!"

"That girl has a nice butt."

"That was amazing."

Seeing Shiori dive for the ball, the men around them began shouting with excitement once again.

"Ah... ♡ Uh, Chika...! The ball!"

"Eh... Ah, uh, okay...!"

Almost swept up in the excitement around her, Shiori sat up and called out to Chika. The sound seemed to snap Chika back to reality, and she hastily tossed the ball that Shiori had just hit back into the air.

"Phew... hah!"

"Oh, wait...! Damn it!"

"Oh no... Ah, I’ve been had."

Once again, Shiori attacked while still standing on the sand. It seemed Range and Talc were enjoying watching Shiori and Chika. This time, neither Range nor Talc picked up the ball, so Shiori and Chika scored a nice point.

"Heh heh... I didn’t expect to get scored on first this time. I got complacent after winning the first set."

"Gotta be careful. Heh heh... Here, the ball."

"...Yes."

Range and Talc expressed frustration at conceding the first goal, but their faces were grinning. As if they were saying that one point was no big deal if it meant they could see Shiori and Chika in action.

Feeling that emotion, Shiori took the offered ball and stepped back to the back of the court.

"Phew... hah!"

"Oh, wait a minute...!"

"Yo...! Hehe, here we go!"

Then the serve. The ball was released and flew to the very edge of the court, but Talc managed to pick it up. Then, using the ball Talc had bounced up, Range suddenly launched an attack.

"Eh, ugh...!"

"Big sister...?!"

The released ball flew straight toward Shiori. However, unlike before, the attack came so suddenly that Shiori didn’t react in time and took the blow to the chest.

"Ohhh...!"

"That shaking was nice too...!"

"That girl’s boobs are nice too. Heh heh, so sexy."

"Your figure is really good, isn’t it? Hehe."

"Uh... uh"

"Ah, ahh...!"

When Shiori received the ball, her chest swayed and jiggled. As the men around them cried out in excitement at the tremor, Chika chased after the ball that had been sent flying—but it was too late, and she dropped it.

"Heh heh... That’s one point back."

"I’m gonna keep scoring points like this. Heh heh."

"Uh... uh, uh... ♡"

"Uhh, uhh... ♡"

Range and Talc grinned slyly at the point they had scored. Receiving that smile, Shiori and Chika felt disappointed at conceding a goal, but they continued to feel a thrill of excitement from the lewd stares constantly directed at them from all directions.

The beach volleyball match continued from there.

Just when it seemed Range and Talc were scoring points, Shiori and Chika would have wardrobe malfunctions, dive into the sand, or have their chests bounce with the ball, but they still managed to score a point. They would learn again, drop it slightly, learn again, and somehow get it back.

Shiori and Chika were doing their best to keep up, even while being toyed with. But the difference in fundamental abilities—being accustomed to the sandy beach environment and volleyball skills—was still significant.

Once again, Shiori and Chika lost the second set as well.

And that meant Range and Talc had won the beach volleyball match.

"Hehehe... We win, sis."

"...Oh, I forgot to mention, but there’s a rule that the woman who loses the beach volleyball match has to be absolutely obedient to the man who wins for the rest of the day. So from now on, you’ll have to obey everything we say."

"That’s how it is."

"I’m going to thoroughly and slowly enjoy that beautiful, naughty body of yours. Hehehe."

"Uh... uh, uh... ♡"

"Uuuu... ♡"

He uttered those words with a victorious smile on his face.

Shiori and Chika were unable to say anything in return. Their hearts simply pounded with anticipation for what was about to happen.
