Reply: I caught a stranger jerking off to me in the parking lot and I let him fuck me r

I was at the grocery store parking lot after picking up a few things, wearing my usual comfy sundress that clings to my big soft tits and shows off my legs a bit. Nothing crazy, but I guess it was enough. I was loading the bags into my car when I noticed this guy in the car next to me. Probably in his late 30s, decent looking, sitting there with his windows tinted just enough. But I could see his hand moving in his lap. He was staring right at me, jerking his cock while watching me bend over.
At first I froze. My face got hot and I thought about just getting in my car and driving away. But something in me snapped. That naughty thrill shot straight between my legs. I could see how hard he was stroking it, his eyes locked on my ass and my cleavage. I don't know what came over me. I walked over to his window and tapped on it. He looked shocked but didn't stop. When he rolled it down I whispered something like "You like what you see, huh?" My voice was shaking but my pussy was already soaked.
He nodded fast, breathing heavy, and said he couldn't help it. I looked so fucking good and he had been edging for minutes. Without thinking I opened his door and slipped into the passenger seat. The parking lot wasn't empty but it felt so risky and hot. I reached over and took his thick cock in my hand. It was throbbing and leaking precum. "Let me help you with that," I said. I started stroking him slow then faster while he groaned and grabbed my tits through my dress.
I couldn't take it anymore. I pulled my panties to the side and climbed right on top of him in the driver's seat. His cock slid inside me raw in one push. Oh my god, it felt so good. So wrong. A complete stranger stretching my wet pussy while cars drove by. I rode him hard, my big tits bouncing in his face as he sucked on my nipples. He kept moaning about how tight I was, how he had been fantasizing about fucking a hot mom like me. I came first, shaking and biting his shoulder to stay quiet, but it was too intense. My orgasm hit like a wave and I soaked his lap.
He didn't last much longer. He grabbed my hips and thrust up deep, burying himself all the way as he exploded inside me. Pumping load after load of hot cum into my pussy. I could feel it filling me up, dripping out when I finally climbed off. We both just sat there panting for a minute. He looked at me like I was a dream. I fixed my dress, gave him a little smile and got back in my car without saying another word.
Now I'm home. My husband is out, my son is at work, and every time I move I feel his cum still leaking out of me. I'm sore and guilty and so fucking turned on at the same time. What the hell is wrong with me at 50 years old? Has anyone else given in to something like this in a random parking lot? That stranger probably thinks about it every day now. I know I will. God I need to stop but I don't want to.
