... breasts.

Mom said, "Are you really going out in that outfit?" Karen, "Mom it's hot, I'm just going with my brother, and no one else is likely to see us." Mom said, "O.K., good, I guess I'm glad that you are comfortable with that sort of dress within the family."

So, we started off to the river, and I caught myself suddenly realizing just how hot my sister was. When we got there, Karen reached down to check the temperature of the water. "The water's warm for this early in the season, so let's go swimming."

"But we didn't bring our suits."

"Who needs suits? We're brother and sister, there's no one else around, we'll just skinny-dip."

With that, Karen started peeling off the few clothes she had on. Soon, she was totally naked and I gasped at her full, firm breasts, tight stomach, and long, toned legs. Somehow, I had only just a few minutes ago thought of my sister as 'hot', but hot she was as she stood there naked.

Now, I had an immediate problem. My 'dick-has-it's-own mind' had risen in my shorts. I really didn't want to reveal myself in this compromising position to my sister.

"I don't think it's warm enough for me to swim in the river just yet,"

"What's wrong, little brother, embarrassed about the erection I can see in your shorts? I'll take that as a compliment any day"

"Oh, I'm so sorry. I never thought I should have any sexual thoughts about my sisters, and until now, I never have."

"Don't worry, as long as you don't try to rape me. I actually ...

... like your reaction to my nakedness; and I'm sure Becky would feel the same way. Now, do you need some help shedding those shorts?"

And without waiting for a reply, Karen came over and forcibly pulled my shorts down. As she bent over after the pull, my fully erect member sprang up and hit her in the chin. She just smiled and finished the job of removing my shorts.

I quickly stepped out of my shoes, lost my t-shirt, and jumped into the river. Mercifully, the cool water quickly deflated my erection, so I didn't feel like a pervert as I swam upstream next to my sister. As we swam up, the flow below some mild rapids became stronger. This wasn't a big river, and no spot was really above my head. There was enough water to swim, however, and my sister, a competitive swimmer in high school and in college, recognized that this was a natural 'endless pool' where one could swim forever at a certain pace and never either gain ground or be pushed back.

So, with me a few feet back, where the current wasn't quite as strong, we swam for 10-15 minutes before my sister decided she was a bit cold. We then waded out onto dry ground and took up seats on opposite logs to dry off in the sun.

After having just talked about school on the way down to the river, my sister wasted no time starting to interrogate me about my 'love life' in college.

"So, Matt, any hot dates your freshman year?

"No, a few coffee and movie dates, but nothing steady."

"Did the movie dates lead to anything ...
