Most of these stories are standalone, so you don't have to read them all. This one, however, follows on the day after Pt 18, and calls back to Pt 11.

We woke up all entangled in each other, and lay there with me stroking her tits for a while. When we decided it was time to get up, we showered and got dressed. I dressed in shorts and a T-shirt, Sue in her slutty schoolgirl outfit from last night, minus the socks. She did do a couple of buttons up on the shirt though, rather than tie the ends together. She was all ready to head home, but I suggested we go and get some breakfast together. She seemed nervous, due to her outfit.
We walked downstairs, and Sue dashed over to her car and came back with her handcuffs. I put them in my pocket, then we walked to the cafe near my place, and grabbed sandwiches and coffee to go, then headed to the park for a little picnic. We sat on one of the benches watching the people go by. Before I gave her her sandwich, I suggested she give me her thong, and she stood up and slid it down her legs, sat down and took it over her feet, then handed it to me. Her knees were clamped together, and her bare butt was on the seat.
She nibbled at her sandwich and sipped her coffee, looking around nervously.
"You look the same to everybody without the thong as you did before you took it off," I said.
"Yes," she said, "but they watched me take it off, so now they know I'm not wearing it."
I thought that was a fair point, and I could see some people were watching us to see what was going to happen next.
"How about you take off your bra," I suggested.
"OK," she said, "will you unhook me so it's not so obvious?"
I reached behind her and unhooked her bra.
She pulled one arm out of the strap at a time, with a short time gap between each. I think she was hoping to do it so nobody noticed, but people were watching her, and they noticed the red bra coming out of the white shirt. She gave it to me, and I put it in a pocket.
When we were finished, I went and threw the trash away, and we carried on walking down the trail.
"I'm pretty turned on right now," she said, "but I don't know that I want to do anything wild out here in broad daylight."
"OK," I said, "let's see what happens."
She took the lead, and we walked away from the open spaces. As we got into the scrub land, she opened her shirt, so her tits were on display. When we were well off the trail, and there was nobody in sight, she took her shirt off and handed it to me while we carried on walking. She stopped and pulled me to her, giving me a passionate kiss, and reminded me about the hand cuffs. I put them on her, with her hands behind her back, then we carried on for a while.
She wanted me to take her skirt off, but I suggested something else. There was a velcro strip around the waist band, and I tightened it, meaning it rode higher on her hips so her butt was now visible from the rear.
Eventually we gave up on the skirt, and I took it off too. I could see we were approaching some of the mountain bike and horse trails, and I pointed them out to her. We could see a couple of bicyclists in the distance headed this way, and she decided to flash them. Well, it wasn't really flashing, she just stood there at the side of the trail as they came up on her.
"Hello there," said the first guy, stopping, "what have we here?"
His friend stopped behind him, and asked if she was OK.
"Yes," she said, "I'm just on a dare to walk around out here naked."
"And the hand cuffs?" he asked.
"Part of the dare," she said.
"What do you get for doing it?" said the second guy.
"I get to suck your cocks," she said.
Without any further ado, they were off their bicycles and pulling their shorts down.
"Naked," she said, "like me."
"He's not naked," said the first guy, pointing at me.
"He's not getting his cock sucked," she said.
They stripped off, struggling with their shoes, until they were both naked in front of her. She awkwardly knelt down in front of them both. She started sucking one, then the other.
We were still on the trail, and I saw another cyclist in the distance, coming our way.
Sue was sucking the first guy for about a minute, then leaving him to jack off at her while sucking the second guy for about a minute, then swapping back. Just as the second guy came in her mouth, the other cyclist arrived.
Sue spat the guy's cum out, and concentrated on the first guy.
"What's going on?" said the girl on the new bicycle. I could swear I recognized her from somewhere, but I couldn't place her.
"She's on a dare," said the second guy, pulling on his shorts.
I watched Sue finish the first guy off, spitting out his cum on the trail. I helped her get up and reached over to wipe the dust and little stones from her knees.
"Are you OK?" asked the girl.
"Never better," said Sue with a smile.
The second guy was dressed by now, and stood waiting for his friend to get dressed too. They both seemed a little embarrassed to have this girl show up when they were naked, so they left pretty much as soon as they were dressed.
"So do you mind telling me what that was about?" said the girl. I realized it was the girl who'd delivered pizza to Sue's, so her name was Rachel. They were both acting like they didn't recognize each other, but I was pretty sure they did. Of course, Rachel had no idea that I'd seen her before.
"I dared myself to walk around here hand cuffed and naked," said Sue, giving a little twirl, "and as a reward, I got to suck off anybody who sees me."
"Really?"
"Really."
"And what's your part in all this?" she asked me.
"I'm here to carry her clothes," I said. "And let her out of the hand cuffs when she's done."
"You're not going to take advantage of her?" she asked me.
"I don't think I could," I said.
"Well," said Rachel after a short pause, "I saw you. Are you going to suck me off?"
This was a new direction for Sue, as far as I was aware she'd never been with another girl. She'd talked about it, but I didn't think she'd ever done more than talk.
"Um," she said, "I hadn't planned on it, but I guess a dare's a dare. You'll have to be naked though, like they were and I am."
"OK, but not here," said Rachel.
"No," said Sue, "right here."
I could see her thinking about it. She looked about to see if there was anybody around, and started undressing. Once she'd pulled her sports bra off, I could see she had nice tits, and when her shorts came down, there was a neatly trimmed pussy. When she was completely naked, she reached over and felt Sue's tits for a short while, like she had when she delivered pizza to Sue's.
"Come on then," she said, "before anybody sees us."
