When Donna and I caught the last city bus on that summer night, I was tipsy but nowhere near drunk. Steady in my high heels, I followed my roommate down the aisle, past the blue-collar workers coming off second shift. 

I wondered why Donna hadn't chosen to sit closer to the front. That was, until I spotted the man sitting alone about two-thirds of the way back. Behind him, the bus was empty.

We sat directly across from him, with Donna closest to the window. Of course, my roommate knew I had a thing for older guys. And I had no idea why this particular guy was riding the bus. He was nicely dressed, his suit coat folded on the seat beside him. Glancing his way, I took in the details of his salt-and-pepper hair and the five-o'clock shadow which was now closer to a midnight stubble. I also noticed he didn't wear a wedding ring.

He briefly looked up, gave me a polite smile, and then went back to reading his paper. He was so close, I could have easily leaned over and grazed his shirtsleeve...

Donna nudged me, as if my thoughts were being broadcast into her brain. I gave her a sidelong look and bit back a giggle.

She and I would be on the bus for a good while, since she'd insisted on dragging me to a bar all the way across town from our apartment. "An awesome band is playing tonight!" she'd told me earlier.

I was far from impressed by the band, but the music was decent enough for dancing. My outfit for the evening consisted of a black dress with a ruffled hot-pink hem. Donna had chosen a stretchy aqua number that perfectly complemented her natural blonde hair. I was a boring brunette and didn't tease my hair as high as she did. At the bar, she'd drawn most of the attention.

Now, she brought her lips to my ear. Her breath was still sweet from some fruity cocktail as she whispered.

I squealed at her words, then cupped a hand over my mouth. The man across from us again looked up. His smile was knowing; I could imagine him thinking, Such silly girls.

Maybe it was the hint of condescension in his expression that made me brave enough to consider Donna's dare. Or maybe it was the understanding that Donna never expected me to actually go through with it.

Before I could lose my nerve, I slipped out of my heels and lifted my bare feet onto the seat. Seeing as how the evening was so warm and humid, I'd forgone wearing any kind of hosiery.

The man was again immersed in his reading and didn't notice my movements.

"Psst, Mister!" I hissed.

Donna grabbed my arm. "Libby, no!" she hissed even louder. "I was just playing!"

I shook her off and turned in the seat so I was facing the stranger, who now studied me expectantly.

Lifting my dress, I spread my legs to flash my black panties. The man's eyes widened.

Unable to suppress a grin, I pulled the crotch of my panties aside so he got a good look at my pussy. His mouth dropped open in astonishment. He didn't appear so condescending now!

This was long before the time when everyone had cell phones, and there were cameras on every street and in practically every vehicle. It was a time when a woman could get away with foolish behavior without it being recorded and uploaded to the internet. 

Still, Donna lunged forward and tried to yank my dress down. 

"Sorry, sir!" she blurted out. "My friend's a bit drunk."

"No, I'm not!" I protested. "I'm perfectly sober."

The man's stare was riveted to my pussy, which I proudly displayed. I glanced at the bus driver, who was either too oblivious or too apathetic to care about what was going on.

To my shock, the handsome stranger set aside his paper and began rubbing himself through his pants.

"Well, if you're perfectly sober," he said to me while masturbating, "I'm sure you're clearheaded enough to appreciate this."

He took out his cock. Even half-hard, it was the largest I'd ever seen.

"Oh... my... God," I squeaked.

The man grinned at my reaction. "Come here, sweetheart. I know you want to touch it."

I did want to touch it! Escaping Donna's last-ditch effort to restrain me, I stepped back into my heels and then crossed the tiny distance of the aisle so I could sit beside the stranger.

Immediately, he grasped my hand and brought it to his dick. My fingers barely encircled the girth! His erection twitched beneath my touch, which encouraged me to start stroking.

Donna must have realized there was no stopping me, because she rose and went to sit in the seat right in front of mine. I figured it was her way of trying to block the driver or any other passengers from seeing.

The man released a faint moan as I pumped my hand up and down, faster and faster. Soon, he was fully erect.

"Sit on my lap," he urged in that low voice I already loved. "Just rub that gorgeous wet pussy against me."

My heart was racing at a dizzying speed, and my mouth had gone dry with nervousness, but neither of those sensations dimmed my arousal. I shot another wary look at the driver, who seemed as clueless as ever. Then I slipped onto the stranger's lap, facing away from him.

Donna looked back at me, her eyes huge. I merely grinned while the man helped me move my dress out of the way.

Now that I straddled his legs, I reached between my own to pull my panties aside again. 

He didn't give me time to settle and rub my slick folds against his cock. Instead, I felt his bulbous tip sliding between my pussy lips in search of its intended destination.

I could stop this by quickly standing up. The man wasn't restraining me in any way. I could move back to my seat and ignore him for the rest of the ride.

But I didn't want to. What I wanted was to feel that massive cock inside me.

When I felt him prod at my opening, seeking entrance, I took a deep breath and sank down. 

"Oh, fuck yes!" he groaned.

My face contorted as I was gripped by panic. Donna watched me, her stare full of alarm.

"Are you okay?" she demanded.

I swallowed hard and nodded. "Oh God, Donna, he's so big!"

The man rested his hands on my hips to steady me. "That's it, baby. A little more..."

My legs quaked, and my pussy throbbed in protest. Yet I took more of that meaty shaft, which was lined with prominent veins. The moment his dick hit a certain spot within me, my eyes rolled, and I could no longer hold myself upright.

I fully impaled myself on his cock. A pathetic whimper slipped from my lips while I struggled to adjust to the intrusion. 

"That's a girl," he soothed. "You've taken every inch of me now."  His fingers snaked between my thighs to rub my clit.

The stimulation prompted my hips to rock. It still hurt, having all of him buried inside me, but the ache quickly morphed into a hot pleasure. I'd never been filled like this! Never had my inner walls been massaged so firmly.

I started moving in a wanton fashion; anyone glancing back would have no doubt about what I was doing. Donna watched all the while, her cheeks flushing scarlet.

"Fuck, he feels amazing!" I confessed.

I swore I could feel him grow even harder inside me. It didn't take long until I was riding him at a frenzied pace, and I heard him panting as his fingers rubbed my clit.

"I'm close!" I told him and Donna. Already, I felt that swell of heat like a strengthening wave in my lower belly.

The man began bucking his hips to thrust upward; I knew he was pursuing his own release. "Gonna come inside you!" he warned, his voice strained.

I made no effort to move away. As my orgasm overtook me and I quaked on his lap, he held me fast. I let him fuck me hard until my pussy was raw.

And then I smiled and moaned at the sensation of his hot cum filling me.

He was still inside, still hard, when Donna alerted me that our stop was approaching. I stood on clumsy legs, trying to keep my dress lowered while ensuring that my panties were back in place. I knew the fabric would soon be saturated with semen.

I shuffled into the aisle. A glance over my shoulder allowed me to see the wet mess the stranger and I had made. He didn't appear at all concerned.

I would have given him my number if he'd asked, but he didn't. He simply wished me a good night. A lazy, contented smile played on his lips.

I allowed my friend to pull me to the front of the bus. Before we got off, I dared to look at the driver. His expression was far more animated as he lowered a hand to his groin. 

"Hope to see you again soon, ladies," he said while rubbing himself.

Once Donna and I stood on the sidewalk, and the bus had noisily pulled away, my roommate and I burst into shrill, semi-hysterical laughter.

"I can't believe you did that!" she shrieked. 

"Me either!" We started walking home, arms around each other. "Swear you won't tell anyone?" 

"I swear!" Donna assured me.

It was a promise she kept.

On that crazy summer night, several years before marriage and a family, before a secure job and a mortgage, I was what I most longed to be.

I was free.
