Boys with cars should try this; it's awesome!
My best friend Jordan and I always head to the gym together to work-out. We have known each other for many years, and have wacked each other off before.
After a nice long workout, we headed back to our car. Jord started talking about the hot chicks he saw working out in the gym. Both of us got hard relatively soon and started talking about wanking off. I wanted to wait till we got to Jord's house, but he said he wanted to do it in our car.
I tried to reason with him, but he just took out his large penis and wacked it in front of me. He threw his shirt to the back seat and start yelling how hot the chicks were. I tried to tell him to stop, because other people could see us, but he said no, and wrestled me, took off my shirt and unzipped my pants.
Jord reached over to grab my dick and I wacked his. He placed his left feet over my right feet, which was over the gas pedal. I tried to stop and I started the car, which resulted in a huge rev from the engine. I tried to push Jord away, but he held my feet over the gas, and let the engine roar!
The vibration of the car was awesome! The sound gave us a better orgasm, and when both of us came, the RPM showed us a big five on our tachometer. We cleaned each other up and drove home.
The next morning, as Jord and I were headed to work, our car had problems starting. We knew what to do to warm up a cold engine! We took great care of our engines, and filled our car with some nice smell of cumm while doing so.
