Amazing. I heard a sound and witnessed the man that had changed seats, bent over and placed his head in the other man’s lap. I couldn’t believe it... A loud moan escaped from one and embarrassed, I turned away. Two young men with big cocks had joined the girls in the shower and were driving into them without a care. I had to release my cock as I didn’t want to cum yet. I had never leaked so much and my hand was dripping. I had brought no tissues and as I watched a fat cock slap a young blonde on.

And I added:-You know that no one can know about this, but absolutely no one, this has to stay between the two of us.-Of course, silly, how do you expect me to tell anyone after this, I wouldn't be crazy to go there," both the answer and the way she said it filled me with.
