In college. Roommate and I had bunks. I’ve slept nude since I was about 8 y/o. Did change in college. I had the top bunk. My morning wood won’t go down till I piss. So, most mornings I’d wake up, usually early, jump down and go take a piss, he saw my morning steel all the time. Gave me shot about it but after a while, it was no big deal.
When I was married and my kids were little, we went to her Mom’s lake home on the weekends pretty regularly. My family all stayed in one room. I always wake tock hard. I would slip on some boxers or briefs and walk to the bathroom. A couple times, her sister who I dated/fucked before I began dating my now ex., walked out of their bedroom and saw my tent. The first time, she smiled and said, “some things never change, huh?” The other times she saw me I think she planned it. Listened for our door to open and rushed out into the hallway to see it. She seemed obsessed with seeing my cock.
