Thats SOOO HOT!!!

My wife and her sister are big into marathons, triathalons, bike races and anything outdoor athletic. There is a race each year where people run a 3 mile course course through a muddy swamp. They get ridiculously filthy. After one such race my wife and her sister came back to my car. I said there is no way I'm letting them in caked in so much mud. I told them they had to change outside the car. So they both stripped down naked and used towels to brush the remaining mud off. I had a full view of my sister-in-law for a good 5 minutes.

Puffynipples I do those mud runs as well and usually there is a fire hose at the end that people crowd around and get showered off. ALWAYS A GOOD SITE there. Wet t shirts and some nudity.

Spray 'em down!
 

If I were you...............
Next time, I would bring two 5 gallon pump-up spray canisters full of water and hose them down yourself. Top to bottom... EVERYWHERE! :D

Maybe it was the first time at your home but for sure it was not at the time she lived with her father.

Perhaps she have grown up walking around in her thong and it was natural for her to be seen like that all the time around her close family,

That's why she might feel relaxed and confortable with her dad. Obviously it was not a big deal between them.

Here's a little story I'd like to share. It's not spectacular, but it's true ;)

I've always had a thing for my SIL (the wife of my wife's brother). She was always very prude and paying lots of attention to not showing anything to anybody. After she had kids, I got the occasinal glimpse at her tits when nursing, so I knew she had large nipples and (then) firm titties. From some panty raiding, I also knew she never wore thongs and only had very convervative undies. I always wondered what her pussy looked like and concluded that the must have a huge bush.

Fast forward: Our families went on vacation together, sharing a condo that also included a pool. One day, my wife and her brother were running errands so SIL and I decided to do share some pool duty with the kids. After some time, we decided it was enough for today and herded the kids to the bathroom to shower and dress them. Once we were done with the kids, SIL took a shower - in her swimsuit of course. When she was done, I went under the shower and she started to towel herself and also sported one of them towel turbans. Her clothes were laying right in front of her and I guessed that she was considering what to do next. I tought: the hell, let's help her a bit with the decision and dropped by trunks, facing away from her and pretending to continue to shower. I never really expected her to do likewise, but when I turned around, she stood there fully naked, giving me an excellent view of the cutest butt I've ever seen and also a side view of her boobs - a lot saggier than the last time I saw them. While I was admiring the view, I saw her reaching for her panties and thought: Okay, it's now or never. I turned off the shower and ran past her, pretending to look for a towel. While doing so, I looked sideways and even though I didn't actually see her pussy, I also did not see a single hair on her mons. So while it is possible there's a tiny little tuft of pubic hair, she obviously shaves at least most of her pussy.

Of course, I had to jack off the second I left the room and hoped to get another opportunity, but sadly she never went to the pool again for the remainder of the vacation.

I remember the first time I saw my SIL's boobs. It had been three years of knowing her, I had never seen a thing. Being she is the "hot sister", I was super curious (even though she is also the insane one you wouldn't want to touch with a ten-foot pole).

One morning, at a hotel, my wife and I walked to her room to see what she was up to. She answered the door in pjs with her arms over her boobs. Eventually, she let her arms down. She was braless, of course, and I could see right through her thin pj top. Super dark nipples, and longest I had ever seen. They were droppy yet her nipples pointed up, and her nipples pointed way out to the sides. And her breasts were about 1/10th the size her bras implied! (My wife has super light nipples that are flat, huge yet perky boobs, so pretty much exactly opposite her sister.) I couldn't concentrate on anything for most of the entire day after seeing that. It was as exciting as seeing her topless after all those years!

A few more years went by and I saw nothing. Then one day she decided to replace her entire wardrobe. Suddenly, while dressing in a way she thought was even more conservative, she started wearing shirts that were a little too big, but covered every bit of skin. But being way too big (and wearing bras many sizes too big), all of a sudden every time she bent over you could see it all. The first few times were insanely exciting (even my wife would notice and comment later), but by now it's old news. I still see her long nips regularly down her shirts even though I never even try.

I still would love to see her totally topless standing up, just because it's a totally different perspective than when she is bending over or sitting while leaning forward. I had a close moment once when she tried on a shirt in front of me braless, but it was an obscured view.

My wife's uncle was very successful in real estate, he didn't marry until he was 40, when he did she was a super trophy wife of 25. Helen was very sweet and as smart as she was beautiful, always a pleasure to be around. One summer they rented a large portion of a resort on the Texas coast for a family reunion, pretty much all of my wife's relatives showed up, it was a lot of fun, lots of booze and lots of food.

One night Helen organized a fishing trip, there was a flare offshore and at night the fishing was supposed to be great. Only a few people wanted to go, my wife and I, Helen of course and another couple of cousins. The fishing was great, but it was windy and choppy, lots of spray, all the women had on were t-shirts, this was the 70's, no bras. Besides the flare we had every light on the charter boat on the attract more fish, so it was a nice show, all the wet t-shirts.

When we had limited out on fish we started to head back, it was about a half hour ride in an open boat, between the spray and the open boat our wet t-shirts were getting pretty chilly. I took mine off because it was warmer without it, the ladies were doing the same with threats not to tell anyone. The charter pilot ended up ruining the thrill by showing the ladies where the life jackets were, still a pretty sexy site.
