My girlfriend and I went to the mall the other day with a couple of her friends. They had come over and we all went in her best friend Sarah's car. My girlfriend and I sat in the back on the way up and back, luckily for me. After hanging out at the mall and having lunch, we went to drop off Jenny at her house, which was out in the country. After we dropped her off, we headed back to town to my girlfriend's and my apartment. We were still in the backseat while Sarah drove.
She said 'now I know why you guys wanted to sit in the backseat'. She was kidding around, she really didn't know just yet that something was going on. She did a couple minutes later, the whole time my girlfriend was stroking my rock hard dick. Tammy kept stroking me, faster then slower, then faster as Sarah drove and would look in the mirror or just plain look back to the backseat to see. We were driving around for a little while on those country roads, Tammy jacking me off while Sarah snuck peaks. I tried to last as long as I could but couldn't hold back.
Aaaaahh, my cream rocketed out of my cock, hitting the ceiling of the car. We went home and Sarah told us to clean up our mess. She wasn't mad, in fact, she laughed about it and said we'd have to do it again sometime. I agreed, then and now.
