Here goes... I can hardly believe I'm telling you this, haven't ever told anyone before.
I was at a nice secluded beach on Okracoke Island, NC on an intensely hot summer day. I was wearing a neon pink thong with a custom, extra large "torpedo" pouch to accommodate my rather well-endowed form. As I slid the "swimsuit" (really quite inappropriate for swimming!) on in the hotel room, it was as if the super thin, clingy stretchy hot pink fabric was being painted on to my form. The sides and back were really just thin little strings that strained to hold on to the pouch, and curved up and over my hips and formed a "Y" in the back, disappearing between my firm, well tanned ass cheeks. I pulled on some super tiny cut off jeans shorts, totally frayed and skin tight, so worn out they were practically dissolving. The top button was unbuttoned and I had a form fitting white Volcom short sleeved rashguard on, which was just short enough to show part of a row of tanned abs above the top of my shorts. I'm 5'11", about 200lbs and about 1% body fat. Huge pecs and shoulders, tiny waist, rock hard abs and bubble butt. I live to work out, and then show off that hard work to anyone who cares to look. I was (still am) a huge exhibitionist, but what happened next was beyond my wildest dreams.
I grabbed a beach towel and some tanning oil and walked out to my M3 convertible and put the top down. The side strings of my thong arced up over the waist of my little shorts and down again. I love that, it's such a tease for others to see. The morning sun felt amazing on my face and warmed me all over. I drove out to the national seashore and parked, found a secluded spot in the dunes, and tugged off the rashguard and peeled off the shorts.
I laid out my beach towel and started to oil up. I was bent over oiling my muscular calves with sweet smelling Hawaiian Tropic when I saw a man and woman appear over the crest of the dune behind me. They were maybe in their late 40s, I was 32 at the time. The man had baggy black trunks on, and the woman had Jean shorts that were so short the white pockets were about 50% sticking out below the shredded hem. Her beautiful, tanned ass cheeks were peeking out below the maybe 3" hem of her shorts. Her purple side tie strings were also curving way above the waistline of her shorts and you could tell she had an excruciatingly small thong on under there.
She had a gauzy white crop top shirt on and I could tell she was wearing a metallic purple micro triangle top over what appeared to be really big (like, DDD) fake boobs. She was a curvy, sexy little thing, couldn't have been more than 5' tall with a body to die for and beautiful flowing blonde locks with dark highlights.
The guy waved and asked if they could lay out next to me. I was pretty embarrassed, but I said sure. This was my first time wearing such a skimpy swimsuit in such a public place. Previously I had just worn stuff like this at my parents' pool while housesitting for them. Just thinking about other people seeing me made me really hard. That just added to the embarrassment. I'm normally about 8" long fully aroused. That's too big for the suit to handle, even with the big pouch. I felt really hot, sweat just cascading down my sides, beading up on my tanned and oiled skin, and starting to soak the thong and turn it semi transparent. I could now clearly see the outline of my engorged cock shaft, head and balls through the material. Oops! I could feel my cheeks flushing with embarrassment.
The couple laid out next to me for about 20 minutes, listening to pop music and oiling up. As the woman pulled off her shirt, I could see that her triangle top strained to barely cover her nipples. The strings were lifted significantly off her chest by her big, beautiful fake breasts. Her "underboob" was amazing.
I could hear snippets of their conversation, which eventually went something like this:
"Honey, stop gawking at him. You're making him uncomfortable!"
"Well, I would, but every time I look over there, his cock looks bigger. I think he's going to burst out of that little suit. He's really asking for it, the way he's acting and showing off in that itsy bitsy suit. Mmmm, yummy!"
She had a lilting southern accent, sounded like Georgia. She was a beautiful, carefree southern belle who knew how to play with a man.
I kept trying to keep calm and keep to myself, but eventually I had to look over at them. The man was reading a book, and the woman was lying face down, legs splayed out and her ample breasts straining in her little top. Her bikini bottom was just two little purple elastic bands that formed a 'Y' and disappeared between her succulent ass cheeks. Now I was starting to strain so hard against the confines of the suit that when I looked down, about 2" of my cock shaft was visible at the top of the suit, peeking out of the top, pushing the fabric away from my pubic mound.
Then the woman noticed me getting more uneasy and decided to really tease me. Looking right at my package, she slid her gold rimmed, purple mirror lens aviators half way down her nose, looked over the glasses with the deepest aquamarine blue eyes, and then she said, making sure I could hear,
"I want that cock, Jim. I want to just peel that slutty little pink bikini off his shaft and blow him while you watch."
I coughed with embarrassment.
