Bikini briefs under swim trunks

[Undyman69]

Yesterday the wife and I hung out with a couple that are relatively "new friends". The four of of us went for a boat ride to the lake and hung out for a bit on the water. While out there the wives were talking and I overheard friends wife say "he's wearing underwear under his bathing suit". I just let it go as the husband and I were on a different topic.

We went back to our place an jumped in hot tub. When the husband got out of hot tub I could clearly see his black bikini briefs through his light blue nylon bathing suit! Even my wife said "he's wearing underwear under his bathing suit". Again I said nothing as were are not that close to them.

Funny thing after the hot tub. We all changed into dry clothes and after my shower I put on black bikini briefs and was wondering if we were matching.

My wife and I were in the Caribbean a number of years back. I was wearing a pair of hot pink swim trunks that didn’t have a liner so I had these on under them

We were out snorkeling and when we were done we got out of the water and walked up the beach to our stuff. As I was leaning forward grabbing g a towel my wife said “wow can CLEARLY see your leopard underwear through your suit” at that point plenty of others has probably seen and I couldn’t do much about it so I just owned it and wore them the rest of that day.

I have certainly done this , all of my swim trunks didn't come with liners , so I have wore my bikinis underneath them. I guess most of my bikinis that I wear underneath could actually be worn on their own . I like wearing my joe snyder and todd sanfield defiant bikinis , it's nice to something on underneath. Went water skiing a lot over this past week and wore a speedo solar, speedo 1.5" cheeky brief and a todd sanfield micro swim brief under my board shorts.
The only time I have got caught was our female friends was walking by me on the dock while I was kneeling down and my black bikini brief was peeking out of back of my board shorts. She gave my a smile and a chuckle , that she had seen my underwear and she knew what style they were.

Here's a skier who is trying a different approach! Won't overheat on this sunny day! https://www.jukinmedia.com/licensing/view/12128

I just wear nylon gym shorts. No lining, so I just have on a bikini brief under it, and it doesn't show through.

When I wear shorts or square trunks, I usually wear a swim bikini underneath. I couldn't see myself wearing sports underwear under swim clothes, especially made of cotton.

If they don't have a liner I'll either thong it or wear a bikini brief (never cotton). Usually when we're out on the lake I'll wear a pair of Soffee Silkies aka Ranger Pantites or square cuts

I usually wear a thong under my swim trunks, but occasionally, I will wear a swim bikini.

They used to make swim jockstraps for wearing under unlined nylon swimsuits, the wet nylon didn't give much support and would bulge dangerously.

That reminds me of a time that I went to an amusement park and went of water log ride and got soaked. Refreshing at first but shorts and underwear were wet and caused a little chaffing, was wearing cotton underwear.
