I was out drinking with friends last night and it was time to go home. It must have been about 2:30am. As I was walking down the high street, a taxi pulled up next to me and asked if I was okay. I told the guy I was fine and carried on walking. As I got a little further down the street, he pulled up again. He stopped his car ask asked me if I had far to walk. I told him that it would take me about 25 minutes to get home. Then he told me that if I showed him my tits, he'd give me a lift home. I thought he was joking, so I laughed and started walking. He told me that he was being serious, and asked if I would. I stopped and thought about walking, then turned back to face him. I looked around to make sure there was no one else on the street, then I pulled my tits out for him. I stood there for about 10 seconds, then pulled my top back over my chest. He pulled up next to the curb, but kept the car doors locked. He told me I he wanted to fuck me. I looked down and saw that he had his hard dick out of his pants. I knew I wanted to, because showing him my tits kinda turned me on. I looked around, and the street was empty. I asked him where we'd go. He told me that we could do it in his car but I didn't want to be closed in with him. We drove down to the channel where we knew no one would find us. While we were driving, I played with his dick and got him hard again. He was an okay looking guy. He looked around 25 / 26. Once we were there, we both got out of the car and hid behind a big rock. I got on my knees and started sucking his dick. I've got full lips, and I stares into his eyes while I pulled his cock through then over and over again. I ran my tounge all over his dick and licked all the pre-cum off the tip. When I knew he couldn't take much more, I stood up and took my top off. I pulled my skirt and underwear off, and down on the grass, while he took his jeans off. Then, he pushed his cock right up inside me, and started thrusting his dick between my legs. My 36GG tits wobbled around as he rammed into me. As he pounded me, he grabbed my wrists and held them down to the ground. He fucked me for around 6 minutes before he said he was going to cum. I was so caught up in the moment, I told him to do it on my face. He pulled out just in time and put his knees over my shoulders. He grabbed his dick and started cumming all over me. I tried to catch it in my mouth but most of it ended up on my cheeks. After we were finished, he got a cloth from the car for me to wipe my face clean. We both got dressed and walked back to the car. It was the most awkward taxi ride home I've ever had. I told him to take me to a street a couple of rows down from mine because I didn't want him to know where I lived. I was so ashamed of myself as soon as it was all over, and I have been ever since. I posted on Facebook that a guy asked me and I said no so that if he told anyone, I would have already denied it had happened. I don't know why I'm writing this post. I guess maybe I need to get it off my chest to get over it. I dunno. Anyway, I hope you've enjoyed reading.
