We left and headed for my friends home in his car. He got me to fondle his cock as he drove the car and this was very exciting for me a young teenager...When we got to his house we went in through the front door and his friend was there waiting. When he saw me he took me in his arms and gave me a cuddle and then his hand went down on my ass. It was getting late and we had a few drinks together and talked about the activity at the car-park.

He knew this wasn't a normal conversation for us. Previously I would have complained that he wasn't taking me too or that I would be lonely without him.
