Picked up my Hot Stepsister and she was Horny enough to let me Touch her Boobs

I was driving through the city, window down, enjoying the warm summer breeze. I saw her, my stepsister, walking down the street, her long legs and tight jeans a clear indication of the day ahead. I pulled over, she looked at me, smiled, and that's when it hit me. I needed to talk to her. I needed to see her. I needed to be close to her.

As she walked past my car, I couldn't help but lean out and ask, "Hey, what's up?" She leaned in, her big, natural tits threatening to spill out of her low-cut top. "Not much," she replied, her voice as sweet as honey. "Just heading home." I invited her into the car, and she accepted, her legs spreading ever so slightly as she sat down.

We started talking, laughing, flirting. It was clear she was enjoying herself as much as I was. Then, I did it. I reached out, my hand brushing against her thigh. She didn't pull away. Instead, her breath hitched, her eyes fluttering closed for a moment. I took that as a sign. I moved my hand up, slowly, gently. She let me, her body language saying it all. I touched her breast, my fingers tracing the edge of her bra. She was hot, so hot. I could see the hard nipples pressing against her white bra.

She let me touch her, let me explore. It was a moment of pure, unadulterated passion. She was horny, and I was more than happy to satisfy that need. The car, the public, it didn't matter. We were lost in our own world, our own fantasy. It was a step fantasy come to life, and we were living it to the fullest.
