A great deal of it! And Izuku gets a fun idea from Itsuka!

"Well, come on, let's get going!" Ochaco cheered, running out to hit the sand, Izuku watching her go as her flesh jiggled in really enticing ways.

"She's got the right idea!" Momo smirked as she grabbed Izuku's arm, and walked out with him and the others. As they strode along the beach, a few other beach goers turned to look at the guy accompanied by several lovely girls. Izuku could almost literally feel the envy some guys were directing his way.

"Hey, Momo, think you can make some surfboards?" Itsuka asked Momo, who raised an eyebrow.

"Oh? You surf?" she asked Itsuka, who grinned and nodded.

"Yeah, I like the beach, and do all kinds of fun stuff at various ones," she replied. "I could show you guys how to surf a bit if you want," she added.

"Sounds good," Izuku nodded as Momo started using her Quirk to make the surf boards. Mei grabbed a pink one, and dragged it off unnoticed as Itsuka gave some basic instructions to Izuku, Momo and Tooru.

"To transition from lying on the surfboard to standing, which is called the Pop-up, you're going to essentially be doing a pushup, moving one foot forward, then stand," she demonstrated, having them practice on the beach first. "Obviously, it goes without saying that you want to do it slowly, and make sure you stay on the board."

"Got it," Izuku noted. "So what kinds of other things do you do on the beach?" he asked as he practiced, watching Itsuka demonstrate again. She had his full attention, and not just because she was in a bikini, though that certainly played a large part.

"Oh, you know, beach volleyball, swimming, collecting seashells, making sandcastles, imagining myself as a mermaid, and... I said that last one aloud, didn't I?" she flushed as Momo giggled.

"...wow..." Izuku replied, having a mental image of Itsuka as a mermaid... There was just something about that mythical creature that was so enticing.

"...well, we've already had you do catgirl Ochaco, maybe at some point, we can try mermaid Itsuka," Tooru giggled. "Actually on that topic, maybe mermaid me too..."

"I'll definitely consider that," Izuku nodded, before picking up his surfboard. "You guys ready to try hitting the waves?" he then asked.

"Hell yeah, let's go!" Momo nodded, running for the surf.
