Coming back from camp, my half brother and I got into his stepdad's Falcon and we were on our way home. We grew up together but since his mum remarried he went to live with her and her husband. We are almost the same age, about ten months apart. You can say that our dad was a pretty horny fellow.
At 16, Darren (not his real name) is tall but chiseled. He loves running and surfing. I on the other hand, a few months older, love to go cycling and swimming. We are pretty healthy and very naughty too. We both have girlfriends but we often like to help each other out with backrubs and handjobs.
The camp was pretty hectic and we didn't get time or privacy to release our loads. I know he was horny because he was getting very fidgety. I let him take the front passenger seat because he gets headaches in the back seat. We told each other we can't wait to get home and take care of our boners.
His stepdad was none the wiser. I pulled on the seatbelt and leant as far forward as I could. I put my hands on Darren's shoulders and started a slow, teasing massage. We then started bombarding his stepdad with stories of our experiences at camp. My hand (to the car door) started edging down toward Darren's waist and he was trying hard to keep a straight face. His voice began going funny and he moved around in the seat.
I passed him a pillow for him to 'lean' on but I meant for him to cover himself up if he was getting too embarrassed. My fingers worked quickly, getting under his waistband and finding his raging 7.5 inch boner. I touched him like I know he wanted and I could feel his back pushing against the seat. That got me more excited and I told him that he owed me a good one.
I was happy to be able to make Darren cum in his pants as he sat right beside his stepdad. He fully rolled down the window so the musky smell of sex would not fill the car. Darren asked his stepdad to stop by a Mcdonalds along the way for a snack. I knew that he wanted to clean up as he was kind of a clean freak.
Back on the road he insisted it was fair to let me take the front seat. He thrust the used pillow at my shoulder as I got into the car. He knew I was not keen on being that close to his step dad. Then he began giving my aching 7 inch cock the same treatment until I shot into my pants. I held his slippery hand down on my cock for a while longer hoping to stop the flow, having cum so hard. I thought I would stain the car seat.
We were glad to get home where we could play around much more freely. But that story is for another time.
