A couple times, yes. First time was when I was very young, while at Huntington State beach, in Orange County California. So they had spaced apart lifeguard towers on the sand, like every so often & then like up more towards the parking area, they had like a corresponding covered hut thing, which consisted of a group of bathrooms, outdoor showers, & what I guess was a creepy ‘changing room’ on either side, one for each sex.
This was one large square room, with a wooden bench that went around the entire perimeter. There was like a utility sink in the corner & a drain in the floor. We never saw anyone go in there, & periodically between enjoying ourselves boogie boarding down in the waves, occasionally we’d wonder around & go off down the beach, or wherever exploring (unattended just like every kid in the 80s). So, long story short, I was in there, swim shorts round my ankles, furiously beating off when the door abruptly opened & a couple surfer guys stood there in the doorway. I figured I would hear anyone coming or have enough time to stop if I thought people were coming, but nope!
I was mortified of course, they kind of froze, then smirked, said nothing, & thankfully just shut the door. I didn’t want to face them on the way out, & was so glad they were not hanging out around there when I sheepishly came out a couple minutes later.
The second time was many decades later, involving me jacking off in my parked car, along the road, in a semi-secluded rural area in the local foothills. Despite my having (what I thought) was a clear view forward & behind me, while having both legs spread apart, no pants on, moaning, practically fucking my hand really getting into it, somehow a swift & silent bike rider swished by my car & directly looked in, making eye contact with me. I managed to see his brief ‘amused’ kind of expression as he zipped by, & I was actually taken back by how unfazed I was about it. In a weird, roundabout way, it was kind of a turn on the more I thought about it.
I realized that the older I get, I’m finding the whole idea of ‘getting caught’ more & more exciting, actually.
These two are admittedly tame compared to other people’s crazy tales, I know. Even friends of mine have had some doozies that if they happened to me, I used to think would have scarred me for life! My favorites are the ones where they’re caught mid-ejaculation!!
