I'd got into the habit of taking Muffin the dog for a walk in the morning, and I was following her down the trail on one of those extending leashes. Quite a way along the trail but coming towards me was a guy and a girl. She was wearing running shorts and a baggy shirt, but he was in cargo shorts so I didn't really think they were together. He was jogging backwards in front of her and she suddenly took off her T-shirt and handed it to him. She was wearing a sports bra underneath it and he seemed to put her shirt in the pocket of his shorts.
This looked interesting, so I stepped off the trail. I was still walking towards them, but I wanted to watch these two to see what they were doing.
They'd stopped running, and she'd walked closer to him. It looked like they were talking. She had one of those strap things on her arm with her phone in it. She took the phone out of it and handed it, the phone, to the guy. He pointed the phone at her and she took the sports bra off! She seemed to have pretty big tits and I watched intently as she took the phone holster thing off her arm and gave it to him as well.
Topless, she ran up the trail to a slight bend almost where I was standing in the scrub, then turned around and ran back to him.
When she got back to him, he handed her stuff back to her but she didn't get dressed again.
Now the guy pulled his shorts down and stepped out of them. Then he pulled his underpants down, stepping out of them, too.
He dropped his clothes on the floor, she said something to him and he pulled his shirt up a bit.
Then she handed him her phone and took hold of his dick. She squatted down in front of him and sucked his dick for a minute or so, then stood up and took her phone back.
He jogged up to the corner and back again. She was laughing at him by the time he got back to her.
They chatted for a few seconds and she handed him her stuff again. This time she took off her running shorts so she was standing there in just a thong and her running shoes.
He gave her the phone back, then bent forward and sucked her nipples.
He took her phone back and she jogged up the trail. As she got to the corner near where I was hiding with Muffy, there were a couple of guys jogging towards her and she tried to cover her tits. I'd been so focused on her that I hadn't even noticed them. Luckily everybody was so focused on each other that nobody had seen me and the dog.
"Don't cover up on our account," I heard one of the guys say.
"Are you OK?" the other guy asked her.
"I was just playing a little dare game with my friend," she said and turned to gesture towards him.
I followed where she was pointing and he wasn't there.
"It looks like he's ditched you," the other guy said.
"Well," I heard her say, "he was bottomless with his cock hanging out. I'm sure he'll come back out when he's got dressed."
"All the same," the other guy said, "I think we should wait with you in case he doesn't"
"Um, there's no need," she said. "I'm sure he's just being shy."
"Let's get off the path, so nobody else sees you," said the other guy.
I moved back a bit from the trail, but could still see them.
He walked a little way into the trees and the other two followed him. He pulled out a water bottle and offered it to her.
"I'm fine, thanks," she said.
He drank for a while.
"So, uh, what was the dare game you were playing?" asked the first guy.
"He, um, wanted to see my tits bouncing around when I ran, so I took my top off. And then I wanted to see his balls bounce around, so he took off his bottoms."
"And your shorts?"
"Well, he said it wasn't far that I'd seen his bum, but I wasn't about to run around naked."
"Oh no," said the first guy, "because that would have been too much."
"Exactly," she said.
"So how did it look?"
"Well, he looked ridiculous," she told him.
"And you?"
"I couldn't see me, but Darren seemed to like it."
Darren. So she knew him already.
"I'm sorry we missed it."
"You didn't see anything?" she asked.
"Not from way over there," he said.
"Well, I guess I could do it again," she offered. Wild.
She jogged a little way, tits bouncing around.
"How was that?" she said, covering my tits again.
"Magnificent," one said.
"Outstanding," one said.
"Thank you."
"So what else were you planning to do, on this run?" asked the first guy.
"Well, I was figuring we'd run for a while, mess around for a while, and then we'd probably have sex or something before I head home to my husband."
She was married and having an affair?
"Does your husband know about this?"
"Yes," she said, "it was his idea. He has a girlfriend."
This was getting wilder and wilder.
"So this is your boyfriend we're waiting for?"
"Oh no," she said, "he's just a guy I matched with on Tinder."
