An amusement park!

"Okay, wasn't expecting this," Izuku admitted a good bit later as they bought tickets to enter the local amusement park.

"I made sure to bring a swimsuit for the more water themed rides," Ochaco gushed, gesturing to her handbag. "...not the special sling bikini one, unfortunately, don't want to be to provocative, given how many kids are around, but it's pretty sexy regardless," she promised him.

"... anything looks sexy on you," Izuku quipped, and Ochaco blushed, but was clearly smiling.

"Thanks, Master..." she purred, a bit of the Neko in her coming out, though her parts remained fully human. "Don't worry, I didn't forget to pack your swim trunks too."

"You planned ahead," he nodded approvingly. They immediately headed for the nearest roller coaster.

"Roller coasters are a lot of fun, aren't they, Izuku?" she asked him as they were strapped in.

"I wouldn't know. I've never been in one..." Izuku said a bit nervously. She looked at him like he had just grown a second head.

"You've... Never been on a roller coaster?" she questioned, dumbfounded. Even with her parent's financial struggles, they had managed to take Ochaco to an amusement park a couple times in the past, so she was having difficulty fathoming how Izuku missed out.

"Nervous wreck as a kid, remember?" Izuku replied. "Honestly, this is still nerve wracking..."

Ochaco grinned. "That's the point, Izuku! That's where the thrill comes into play!"

Izuku was about to reply, but immediately started screaming as the roller coaster took off.
