I had been teasing my fiancé for a while at home. I would kiss his neck, slip my hand down his pants, and play with him until he got hard. Then I would stop altogether. I would do this off and on for a few hours at home. Then it was time for us to go out on our date. He was so worked up from me playing with his cock that he had become grumpy. So we got in the car and I started feeling bad for turning him on and then not making him cum. As soon as he pulled out of the driveway, I undid his pants and pulled out his throbbing cock. I leaned over and slowly slid my mouth down his shaft. He groaned extremely loudly out of appreciation. I then added my hands, giving him a blow job and a hand job alternately. He could barely keep the car on the road or his eyes on the traffic, but that's what made it so much fun. He came so extremely hard as his cum hit the back of my throat. Sometimes I still give him this extra treat while he's driving, just to let him know how much I love his cock.
