It's a tiring run with Katia!

We started jogging around the park. She went in front of me, as if guiding me. I could only see her chiseled back and her firm, bubble butt as she ran. She made it look so easy, but I started having difficulty to breathe after two minutes.

"Come on, dude! You can't seriously be getting tired already!" She spoke normally, as if she weren't using her lungs for exercising.

"I'm... A little out... Of shape..." I mumbled.

I thought she'd sprint away, but she started going more slowly, until she got on my level. She was still raising her legs high, fast, as if climbing some invisible stairs.

"A little? Dude, you need to get better at this. Regulate your breath. Don't just pant like a dog, breathe with intention! You make your own rhythm!"

She totally sounded like a coach. She was chuckling at my weakness, but she wasn't directly making fun of me. On the contrary, she was encouraging me to keep going. She even found time and energy to flirt with some of the women we jogged past.

I couldn't even last ten minutes of jogging. Katia was barely sweating, while I felt like dying.

"You could be doing better, dude. You need to exercise a whole lotta more!"

"I'm... Sorry, I... I can't..."

I had to stop, so I sat on a bench to catch my breath. She shrugged at me and kept going, and ran around the park for a long time. It was unreal how long she could exercise. She even chatted with the lady she had pointed at before, and she even made her blush and giggle.

"Ready to continue?" Katia approached me, with the brunette following her.

"I mean... I think I've rested a bit, but..."

"Let me tell you something: why don't you wait for me at the apartment and sit for a bit longer? I'll keep exercising with Linda" she gestured towards the girl and she waved at me shyly. "And then I'll meet you there to continue working out. Alright, man?"

That sounded like a great idea, as I definitely needed a break, even if it was just after warming up. Would I cool down? I didn't care, I needed to breathe.

"Sure."

"Great, dude."

She slapped me on the shoulder (a little bit too hard), grabbed Linda's hand, and jogged away. I waved goodbye at them and took a minute to rest. When I finally stood up and started walking home, I noticed Katia and Linda weren't in the park anymore. Where had they gone?

I was wondering if I should call Sarah and tell her, when my phone rang.
