She starts by taking the owner to stretch with her before swimming

After a long day of helping out around the Venus island, Honoka called up the owner of the island on a date with him. She felt like both of them deserved a nice day off. Honoka picked out what swimsuit to wear while the owner writes down his requests for the staff for that day since he'll be busy with Honoka. After getting changed in their respective dressing rooms, they meet each other outside there. Honoka shows up wearing a rather skimpy bikini, even for her standards, which leaves the owner a bit flustered.

"What? Is this too much? I would've thought this would've been more your style." Says Honoka teasingly.

"Oh no, it's fine, it's just I didn't expect you to wear this little I guess." The Owner responded, red in the face.

"I think Leifang told me that we should try to do stretches before we go swimming." Honoka said.

"I guess that makes sense, I mean most people don't really swim in a poll or on the beach as a sport but it works for any of the others." The Owner agreed. "Did she or anyone else give a good routine for this btw?" he asked.

"Um, not that I can think of, no." she answers. "I guess we'll just have to figure something out."

"Ok then, well I guess I'll just do standard track and field stretches. Just follow along with me ok?" he tells her. Honoka obliges.
