Lisa wasted no time helping me buy a full set of cycling gear for our weekend adventure.

But when the package arrived, I was confused. She must have made a mistake when ordering because the cycling outfit I got was… a schoolgirl uniform.

I thought it was odd, but the real shock came when Lisa sent me a photo of her own cycling outfit. It looked like she was fully suited up for a hardcore ride, but then she added a teasing note: the outfit was actually a cleverly designed lingerie set.

I was speechless. All I could send her were three question marks.

Lisa's response was cryptic and mischievous. "You don't get it. This is where the real fun of cycling lies."

"Think about it," she added, "all those tiny pebbles on the road, the bumpy mountain paths, and the feel of the wind… combined with a little ‘freedom' underneath. It's like flying."

"I had this custom-made," she continued. "Yours is a bit more conservative than mine, though. I figured you couldn't handle my level of boldness just yet."

Her wild imagination left me both in awe and nervous. But her vivid description of the ride—it was so detailed I could almost feel it—had me feeling restless. I started to look forward to it.

The next morning, Lisa arrived at my door bright and early. She came by car so we could both have our bikes folded and stashed in the trunk.

"We've got a specific cycling route planned," she explained. "It's a bit far, so you can sleep on the way. I'll wake you up when we get there."

Still buzzing from everything she said the night before, I hadn't gotten much sleep. So, I took her advice and dozed off for what felt like a good while.

When she finally woke me, I blinked groggily and glanced out the window, only to realize we were in the middle of nowhere—a remote, isolated place.

"We're here! The founder of the cycling club rented this whole mountainside. It's pretty far out, but the perk is we've got the place to ourselves. No one to interrupt us, no rules to follow," Lisa said, her excitement evident as she patted me on the shoulder.

"The road gets really narrow from here on, so the car can't go any further. We'll have to bike the rest of the way."

With that, she jumped out and began unloading our bicycles from the trunk.

Just before we started riding, Lisa gave me a once-over. Her eyes lingered on my school-girl uniform, and a mischievous grin spread across her face.

"The wind up in the mountains is strong, and the road is rough. You're in for quite the experience in that outfit. Just enjoy it."

With Lisa's playful laughter ringing in my ears, I embarked on my first cycling trip. It didn't take long before I realized exactly what she had meant by this being a "unique experience."

Lisa wasn't exaggerating. The bumpy mountain paths made the ride challenging, but that wasn't the only thing keeping my attention. The custom cycling outfit she had given me was designed for just this sort of terrain.

As the rough path jolted the bike beneath me, the thin material of my shorts pressed even more snugly against the seat, and every little bump sent a shockwave through my body.

I couldn't decide if it was pleasure or pain that I felt as I pedaled harder and harder, trying to maintain my focus. Each tremor seemed to amplify that sensation between my legs, making it impossible to ignore.

Lisa, on the other hand, was completely in her element. I could see the flush of red across her cheeks, but she looked exhilarated rather than embarrassed.

At one point, I even noticed a wet patch spreading across her bike seat. I didn't need to ask to know what that was, and it startled me to realize how far she'd taken this.

Lisa, who had always seemed so composed and proper, had hidden this wild side from me. If it hadn't been for our late-night heart-to-hearts after my breakup, I might never have known.

Before long, we reached the "club spot" Lisa had mentioned earlier. It was a wide, flat area with two large tents set up, and to my surprise, there was even a small mountain hot spring nearby.

As soon as we arrived, four men came out to greet us.

Lisa wasted no time introducing me, particularly to the man she referred to as "Tim Greene," the club's founder.

"Tim, this is my bestie, Julie," she said with a teasing lilt. "It's her first time joining us, so be sure to take good care of her."

There was a glint in her eyes as she bit her lip and winked at him, silently conveying a message I couldn't quite decipher.

I, on the other hand, stood off to the side, feeling both shy and out of place as I murmured my greetings.

The men's gazes flitted between me and Lisa, their attention lingering a little too long on our bodies. One of them quickly noticed the intricacy of Lisa's outfit.

"Lisa, your outfit today is even more stunning than the last time…" he commented.

Before I knew it, two of the men had slipped their arms around her waist from either side. One of them even boldly gave her a squeeze on the rear.

Lisa, nestled between two men, didn't resist at all. Instead, she seemed to revel in their attention, playfully hitting one of them on the chest with a mock pout.

"Stop it! Julie is still here. Later tonight, the three of us can have some fun."

My eyes widened in shock as I watched them banter, and a strange thought flashed through my mind. Could she possibly mean... that kind of fun?

Before I could process the situation further, Tim—whom Lisa had introduced earlier—stepped forward, trying to wrap his arm around my waist.

He was dressed in a sleek black sports outfit that clung to his muscular frame, his abs clearly defined underneath. Despite his imposing figure, the way his eyes lingered on me made me uncomfortable, like he was sizing me up. I could feel my heart racing with unease.

I quickly dodged, pretending to be tired from the cycling. "I'm feeling a bit worn out from the ride. I think I'll head to the tent to rest," I said, hoping to get away.

Lisa gave me an amused, teasing smile. "Oh, but you'll need to choose a tent carefully. There are only three, and we usually pick numbers to see who shares with whom."

What? My mind raced.

If I didn't draw the same number as Lisa, did that mean I'd have to share a tent with one of these strange men?

The idea of spending the night alone with a man I barely knew sent a wave of panic through me. Alone in a tent with a guy... it wasn't hard to imagine what might happen.

My face turned bright red, and I stammered, "I-I'm not sure if that's a good idea..."

Lisa burst out laughing at my reaction. "Relax, I was just messing with you. You'll be sharing a tent with me tonight."

Only when she said that did I finally breathe a sigh of relief. It wasn't that I was a prude, but this was the first time I was meeting these people, and I still felt the need to maintain some dignity.

The afternoon passed quickly as everyone settled in. The group, clearly familiar with the routine, organized a quick picnic before discussing the next activity.

Lisa suggested a race. "Let's carve out a path through the mountains. Each of the four men will partner with one of us girls, and we'll see which pair reaches the finish line first."

Then she looked directly at me, that sly smile back on her face. "As for the reward... The first two pairs to finish fastest get to enjoy the hot springs tonight... with the ladies accompanying them."

She paused dramatically, letting the implication sink in. "Oh, and it's the kind where we are all undressed..."

Lisa's bold suggestion left me utterly stunned, and my heart raced wildly in my chest.

I wanted to refuse, but with everyone else so enthusiastically agreeing, I found myself silently nodding along, unable to say no.

Inside, a small voice mocked me, 'You're probably more excited than you're pretending to be.'

The first man to pair with me was a chubby guy.

The route they had chosen was steep and winding, not exactly easy terrain. He struggled a lot, and pretty quickly, he was panting and waving his hands in defeat, saying he needed a rest.

Left with no other choice, Tim—who was supposed to be Lisa's partner—took over the chubby guy's spot. He was visibly stronger than the others, and everyone seemed to think he had the best chance of winning.

As soon as the second round began, Tim lifted me effortlessly onto the front crossbar of his bike, pulling me tightly against him before speeding off.

With my back pressed against his broad chest, I could feel his hard muscles, and the realization struck me—I was practically counting his abs in my mind. Eight, to be exact.

Whether by accident or on purpose, he seemed to ride straight over every bump and stone, sending me bouncing up and down on the bike.

Before long, an odd sensation began to build inside me.

I tried to ignore it, focusing on the rocky path ahead, but it became impossible when I felt something firm pressing against my lower back. My thin underwear offered no barrier at all, and I bit my lip, terrified that he would notice the effect it was having on me.

Thankfully, Tim's stamina was impressive, and he easily completed the course where the previous chubby guy had struggled. We were the first to reach the finish line.

As we waited for Lisa and her partner, we made idle conversation. I kept expecting them to appear any moment, but time passed, and still no sign of them.

My discomfort grew, not just from the awkward situation but also from the sticky sensation between my thighs. Embarrassed, I didn't dare mention my need to clean myself up.

Finally, I awkwardly asked Tim if I could step away for a moment.

"They should be here soon. I'll just be quick, I promise," I mumbled, making an excuse about needing the restroom.

I headed back towards the forest trail we had come from, searching for a secluded spot. Once there, I quickly pulled out some tissue from my pocket, wiping away the shameful evidence of my earlier arousal.

As I prepared to head back, something caught my eye.

Through the trees, I saw a bike slowly making its way along the trail. It was Lisa and her second-round partner. But something was off. The route we had mapped out was completely different, so why were they here, taking their time like they had no intention of winning?

Lisa wasn't even sitting normally on the bike. She was straddling her partner face-to-face, her thighs wrapped tightly around his waist, and the unmistakable sound of her moans floated through the air.
