We talked about the various things to do while we were camped at Kalalau and came to a consensus that we should split up and spend the day separately as couples, meeting up in the evening to compare notes and, of course, share the tent again. Ann was still tired from the strenuous hike in, so she and Leon opted to spend the day hanging around the beach. The rest of us would hike up the valley.
Birte and Michelle started to put their hiking shorts on.
"Wait a minute, what do you think you're doing?" I asked rhetorically. "We're here in paradise. We don't need to put clothes on until we get back to civilization." They both laughed and put their shorts back in the tent. We all would just wear our Teva sandals for the day. We put together some food and water for lunch and loaded it into stuff sacks, which Sven and I carried.
We started up the gentle trail that followed the creek which had formed the Kalalau Valley. About half a mile up from the beach, we caught up with another couple who were also hiking in the same direction. They were dressed in shorts and tank tops, but didn't appear to be upset with encountering nude hikers. I asked how much further to the spot where the trail split. The lady said they had been to the waterfall yesterday. The split was just a half mile further and there were some very nice wild guavas growing near the junction. We chatted a while longer and I noticed the guy kept checking out Birte and Michelle when he thought nobody was watching. We continued on up the trail while the other couple rested.
The climbing got steeper for a while. Michelle was in front of me and the incline in the trail put her lovely ass right in my line of sight. I couldn't help watching her muscles flex as we moved up the trail. Then I felt a playful slap on my own butt. Birte jokingly said from behind me "Don't get too interested in that view. You're mine for the rest of the day." We all laughed and it was only a few more minutes before we reached the trail junction. At that point, we could go left to a beautiful waterfall or right to a small swimming hole. Michelle and Sven wanted to see the waterfall, so I gave them directions and then Birte and I headed off to the right.
It was almost another half hour of hiking to the swimming hole. The day was getting hot and we were both sweating up a storm. When we finally got there, the water looked so inviting that I just dropped the stuff sack on the edge and we jumped in without even bothering to remove our sandals. The refreshing water cooled us off very rapidly as we stood in the shallow end of the pool. We helped each other remove our sandals and then swam around the deeper part of the pond, playfully chasing and dunking each other. After about 20 minutes, we drifted back toward the shallow end where we entered. When we got to a point where we could stand on the bottom, Birte turned to face me and put her arms around my neck. We leaned toward each other and her nipples, hard from the cold water, touched my chest. We kissed, gently at first, then more passionately. In some ways this seemed more intimate than what we had already done that morning because we were alone together. Birte let herself float up and wrapped her legs around my waist. My cock got stiff very quickly as it rubbed against her pubic hair. Then I felt the heat from her pussy itself. She took one of her hands off my neck and reached down to guide me into her. I started to slowly slide in and out. As we gradually increased the tempo, our movements started splashing against the rocks on the bank. We both laughed at this and continued our rhythmic motions.
After a while we decided to move up to dry land. Birte crawled out of the water and lay down on the soft grass on the edge of the pond with her legs invitingly apart. I got out of the water and, rather than resuming our fucking, I dove head first for her pussy and started to devour it. I started by gently tracing her lips with my tongue, then flicking her clit every once in a while. She started squirming from my efforts and after a few minutes she said "I want to taste you also". So I moved around and positioned my cock above her head in the classic 69 position. As I continued enjoying her taste and smell, she paid attention to me as well. Her tongue slowly traced the length of my cock, then gently swirled around the tip. She opened her lips and slowly took it in, pulling down on my hips to get all of it into her mouth. Birte started bobbing up and down, gradually increasing the tempo. At the same time I was getting more aggressive with my explorations, plunging my tongue all the way into her pussy. She removed her mouth and I heard her moaning in response to my efforts.
I was working up quite a sweat and so was she, as our slick bodies glided over each other. She took each of my balls into her mouth one at a time and swirled her tongue around them. That and the vibrations from her moaning got me very close to getting off. She must have sensed that because she broke away for a second and said "I'm gonna cum" before she took my shaft back into her mouth and began bobbing up and down in a frenzy. I increased my pace as well and in less than a minute I felt my orgasm building as my balls retracted and my toes curled involuntarily. Within seconds I was past the point of no return and my hot semen was shooting into her mouth. That set her off and she started to buck her hips up and down. I managed to stay connected and actually felt her vagina contract on my tongue as her body stiffened. She took her mouth off of me and let out a soft scream as she went over the edge. After her orgasm subsided, I rolled off of her and collapsed on the grass next to her, both of us gasping for air as the sweat poured out. After a minute my body was getting back to normal.
