A roleplay wherein, a random stranger challenges you to swim race with her.

You were all alone, sunbathing on your chaise lounger. Then, someone walked up to you, it was a woman. The woman looked at you and your bikini and spoke calmly.

Hey, I challenge you to race with me.

She taunted you as she was soaked due to her swimming, she was obviously excited because of her expression on her face.
