When I got to the bar she was a bit tipsy and asked if we could go for a drive and talk. We did and she revealed a bit about her life and we ended up...parking an a secluded street and having sex in the front passenger seat. She was so hot and wet that the sex was great. When she whispered in my ear asking if I could see anyone watching us it became apparent that the thought of it turned her on. When I said that the lights just went on in a house about 100 feet away she came so hard --- she. "Well, I thought your sister," he said."What! My sister!" I exclaimed, "why her?" Two reasons really," he said with a sly smile, "one she's drop dead gorgeous and two she available, you know, we going to need time and a place to use this stuff." But she's my sister," I said, but I had to agree with his logic though, she was the best looking girl around."Look mate," he explained, "you're always complaining what a bitch she is and how you would like to get even with her, well now's your chance.". . nothing... A rock hard bulge in his trousers twitched involuntarily against her smooth, flat belly. She could feel the dampness between her legs renewed as her suddenly salacious thoughts envisioned what the huge swollen member would feel like worming around deep inside her. There was no turning back now. It was good... soooo good. And almost eagerly she let Martin draw her lips to his and kiss her, softly at first, then more urgently.Her lips were pressed hard against his, open and willing. She got frantic and screamed for me to “Put it in, put it in,” but I tortured her by just bumping and rubbing my engorged cock-head against her swollen lips. I let the tip in just enough to feel the fat slippery lips and then pulled it out, again and again a tiny bit more each time. I kept feeling the ridge of my cock popping the lips open. Then, I pushed it in all the way, hard. I don’t remember much detail after that except we were both bucking and grinding and grunting like animals. My cock.
