I was asleep, The caller laughed and asked if she had woke me up. It took me several seconds to realize it was my sister.”Oh… hi, preeti,” I gro...ned.”Were you asleep or are you tired?” she asked, laughing louder.”Asleep… well, almost,” I said.”Want me to let you go back to sleep?” she asked. I sat up and leaned back on the headboard of my bed. I cleared my throat and ran my hands through my hair. “No, it’s okay,” I said. “I’m awake and don’t have to get up too early tomorrow.””I just wanted to. I asked if she wanted me to pull over so she could do it and she said no just keep driving. I said fine but I need to stay in the right lane and not pass people so no one can see. She looked at me and said if I didn't drive the way I normally do I wouldn't get anything from her for a while. I said what about people seeing, she said "oh well". I said ok but people will see and she said, "I hope so".I figured I had to do it so started driving like I normally do. Luckily traffic wasn't heavy. All. His hand back on my ass, now rubbing his cool jizz into my cheeks. I hoped no one would notice my messed up stockings.I think my wet ass made him horny again? He was whispering in my ear after the 2nd drink. 'Let's go outside love,' he said.We went out and round the back into a dark corner in the car park, It had stopped raining now thankfully.He grabbed me and reached down to kiss me, his hands never left my ass.'Love, this boy needs you again, wanna play with that big fucking ass of yours. He lubed it very well and put the head against my asshole. He held it with one hand and took a picture of it with the other hand. Then he started pushing, he said for me to try pushing against him, finally the head popped in, and I let out a scream, because it hurt. He didn’t pull it back out or anything, just let it sit there dangling out of my ass as my ass relaxed. Boy did it hurt. He took a picture of this, then he started pushing it slowly in. Finally he got the whole thing pushed.
