I was running late for work, so I had to take the bus. As I boarded, I noticed that it was mostly empty, with only a few passengers scattered throughout. I took a seat near the back, hoping to avoid any unwanted attention. But as the bus started moving, I felt an undeniable surge of arousal.

My mind wandered, and I found myself fantasizing about the guy I had been flirting with at the coffee shop earlier. I could feel my heart racing, and my pants getting tight. I knew I had to do something about it.

I discreetly slid my hand into my lap, rubbing softly at first, then gradually increasing the pressure. My breathing became heavier, my eyes closing as I lost myself in my fantasies. The bus was still mostly empty, and I knew I had a few minutes before anyone else would board.

I decided to take a bigger risk. I opened my legs wider, giving myself more room to move. I slid my hand further down, feeling the heat between my legs. My fingers found their way to my clit, and I started rubbing it in slow, circles.

I closed my eyes, imagining the guy from the coffee shop kneeling before me, his mouth on me. The bus jolted slightly, but I barely noticed. All my focus was on the pleasure building within me.

As the bus stopped at the next station, I glanced around to make sure no one was watching. The coast was clear, and I continued, my breathing becoming more erratic. I was on the brink, and I knew it wouldn't be long now.

Just as the bus was about to pull away, I came with a sudden rush, my body shaking with the force of my orgasm. I quickly composed myself, adjusting my clothes and wiping my hand discreetly on my pants.

No one had noticed, and the bus continued on its route. I arrived at work a few minutes late, but I couldn't help feeling satisfied, knowing that I had just experienced a thrilling and secret pleasure.
