I was a bit dingy from the sun as I climbed up the steps of the bus and worked my way to the back. The bus that would return me to the city was crowded with beach goers and there were no seats left so I stood in the aisle in the swaying mass of bodies, smelling the scent of of seawater and coconut oil as the bus lurched off down the rough dirt track that was the beach road.
After several more stops, the already crowded bus was becoming more like a college fraternity prank as more people got on and I found myself crushed between two pretty young girls in their bikinis; one dark haired with large breasts and the other, a blond sporting a tiny orange bikini beneath a see-through coverup. I was honed and tanned from working construction and a week's vacation in the surf. The young women, smelling sweetly of oil and girl sweat, eyed me appreciatively and murmured apologetically as they were pressed backwards even more tightly against me as more passengers got on.
The bus started up once more, making its swaying, rumbling way down the beach, the back of the bus very warm from all the perspiring bodies. I had become distinctly aware of the pressure of the darkhaired girl's glistening firm body against mine just as we hit a large pothole. She lost her footing and I reached around to steady her, my palm with fingers spread against her warm tummy just above the line of her bikini. She tried to turn and smile as I held her on her feet but the crowd was too tight.
By this time I was becoming so aroused by the feel of the her body swaying against mine that as much as I tried to ignore the situation, I soon developed an aching erection which seemed, as the girl was just the right height, to exactly fit into the space between her tanned legs just under her bikinied buttocks.
As the bus lurched and bumped down the road, she became aware of my cock as it pressed between her thighs. She gasped and turned open mouthed, just enough so that I could see a surprised but mischievous smile on her lips and with a laugh she squirmed her well rounded hips and buttocks against me deliciously, causing my cock to strain against the crease formed by her pussy and the thin nylon of her swimsuit.
As the bus resumed its lumbering, jerking progress with the mass of people in the back of the bus crammed tightly shoulder to shouder and hip to hip, her pretty blond friend was pressed into my side and she could just see the the progress of my hand, still palming her friend's stomach as it moved downward across the darkhaired girl's oily, sunwarmed skin. The blond girl licked her lips, her jaw slightly dropped in riveted amazement as my fingertips dipped into her buddy's navel and moved under the bikini bottom to cup the girl's mound. I heard an intake of breath from the blond as I gently traced and probed her friend's slit.
