My mom’s side of the family used to have a small beach house that was shared among three families, her cousins. One of the families had 5 boys and one girl who were a little younger than my mom. So they were in there late 20’s when my mom was in her late 30’s and Me and my brother were just kids.
Some times the family’s would overlap by a few days at the beach house and we would bunk with 4 or 5 of these guys in the same large built out room in the attic. They were on vacation from college or their jobs and all hanging out for the summer. Sharing a room with them my brother and I would see them in all stages of clothes and unclothed. Most of them slept in boxers or tighty whities. But they were very comfortable changing and being naked around each other. Dicks and morning wood were a common sight in the morning. Big bushes were also very common as it was the early 90’s. They all played sports, field hockey, soccer and track, so they were all in amazing shape. They treated me and my brother like we were two of the guys, even though we were just hitting puberty ourselves.
I distinctly remember one time when we all when to the beach for the entire day, and forgot that we all had to change to go to dinner in a hurry. So instead of showering individually, we all jumped into the outdoor shower at the same time. They guys all stripped off their suits and just hung around the outdoor shower, pushing and taking turns showering off. I did the same and fought to get a spot under the shower. Though I’m sure they let me in. Saw everyone’s dick in that shower. Most were the same size. The oldest brothers was super thick. And the youngest hand a pretty small dick in comparison. I was barely sprouting pubes but they treated me like one of the guys. Thought it was really cool how open they were to being naked around one another.
