Fire Island fun

When I was younger I used to take my boat to a public beach next to the fire island pines...walk west and try and see the guys playing in the dunes. This particular day, I had my spot and was watching two older guys...I was only 15 or 16...really going at it. I think they knew I was there watching but that didn’t deter them. The one man was topping the other guy and really giving it to him. The sounds were remarkable and a****listic. The bottom guy was really enjoying it very much...stroking his cock really hard. I was loving it and stroking my own cock as well. The top man put out a loud grunt and came deep in the bottom man. At that point I was moaning myself and soon, both men were watching me and encouraging me to work my own cock. The top mans cock was very large...perhaps 7+“ inches, uncut and the bottom man was about 5”...mine was almost 6”. They were really encouraging and soon I was ready to shoot. The bottom guy positioned himself to catch my load and was soon rewarded with a couple of good shots on his face. He suddenly took my cock in his mouth and continued to drain me...freaking amazing! When he was done, or should I say when I was done...he told the top man that nothing was better them young cum. They asked if I wanted to come back to their house with them to continue to play...I chickened out and said I had to get back to the mainland. I wonder what would have happened?
