Sex with the boyfriend of my best friend

It happened few days ago, after a party. I couldn't go to the party with my car so I asked to my best friend, Kira, if she could bring me there. She couldn't so we went there with her boyfriend, Josh. After the party, we were all d***k, me, Kira and Josh and Josh brought us back home. Kira's house was few km far from the house of the party, so Josh brought her for first and then he wanted to bring me home since my and his house were pretty close, on the same main street. It was something like 2.30 or 3.30am, I don't recall exactly. I just remember that when we were near my house, in front of the fish and chips I often go after school, he stopped the car and started touching my legs. Josh was a nice guy, but not my type of man. But I don't know why, I was horny and I accepted his avances. We made sex in the car, I don't remember exactly what we did, I just remember that when i woke up, my pussy was still wet. And it was not a dream, I could still see his cum on my pink thong
