Make her want to undress.

You could evaporate her outfit from existence with a thought. But that was too quick. No, there were ways to make this more fun. You keep up behind her, she's jogging and vibing to her music. There was more fun to be had with nudging free will. You begin to whisper into her mind, barely audible beneath her music and her own thoughts.

Wouldn't it be fun to take those shorts off?

She blinked and slowed her pace until she came to a halt. The jogger glanced at her shorts, blushing with a small smile. It was early morning, sparsely populated. She knew undressing in public wasn't okay... but she was jogging alongside the beach after all. Her hands smoothed out the material of her shorts as she nibbled her lip.

You could just say you're wearing your swimsuit.

Her fingers danced along the hemline of her shorts. If anyone asked, she could claim she was planning on swimming later. With a deep crimson blush and a giggled, the jogger gripped her shorts and began lowering them to her legs. All the while, her heart-rate began a steady climb, while adrenaline started to supplement her veins.

The shorts hit the ground, and she stepped out of them. Her plain white panties greeted the morning sunlight. They didn't match her sports bra, making the swimsuit excuse flimsy at best. But you weren't thinking about that.
