The summer was the hottest on record, and we had to go swimming in the river several times every day to cool down. We had been married for just two months, Lisa and I, and we were still in that glorious horny phase, wanting each other all te time. But since Lisa wasn't on the pill, we used condoms.
Our cabin was right by the river, and there was a pool just half a mile upstream that was great for taking a swim. First time we went up there, we swam a for a long time before we had sex on the cliffs by the riverside. The sex was great, even though I missed getting blowjobs. Lisa wouldn't do that.
The day was hot and sunny. We didn't chance on skinny dipping, because of the hiking trail that was nearby. But after some deliberation Lisa decided to take of her bikini top, and swim topless at least.
We were just coming up from the water when we heard someone coming along the trail. It turned out to be Arnie, a friend from when we were kids. Well, kind of friends, sometimes he could be quite a bully. I tossed the bikini top to Lisa, and she quickly covered up.
Arnie said hi, and I introduced him to my wife. He sat down on the rocks with us and we made some polite small talk. I was mostly waiting for him to leave.
"I used to bring girls up here all the time when we were growing up, you know," Arnie said to me. "Some pretty wild stuff happened here, both in the river and on the cliffs." He laughed. "Remember Annie Luntz? I brought her here a virgin, she left a... Well, something else." He laughed a loud, self-satisfied roar.
"Yeah, I remember Annie." I was crazy about her back in high school, but never picked up the courage to do anything about it. I always thought of her as unattainable. Actually hearing about Arnie having sex with her, taking her virginity gives me an unpleasant sting of jealousy.
"But I guess there's not much of that going on here now," Arnie said. "You prudes are just cooling off, looks like."
"Prudes?" Lisa said.
"You were so fast putting that bikini top back on, afraid of anyone getting a peek. Not that there's much to peek at."
"What do you mean?" Lisa asked crossing her arms.
"Don't get me wrong," Arnie replied. "I kinda like small tits. Flat chested girls can be pretty sexy sometimes."
I looked at Lisa, expecting her to get annoyed or even angry.
"Honestly, do you think my boobs are too small?" she asked, no anger in her voice.
"Hard to tell. Take your top off, so I can see."
Lisa blushed visibly, laughed and shook her head. But then she turned her back to him, loosened the straps and actually took her blue striped bikini top off. Then she turned towards him, covering her tits with her arm. She slowly uncovered them in all their small but tight b-cup glory. I was really surprised how daring she suddenly was. My pulse found a new gear, starting to race.
"You know," Arnie said, studying her, "the important thing is how they feel. If their good to touch and squeeze."
Lisa looked at me, jaw dropping in shock at Arnie's impertinence, seemingly. But she couldn't hold back a smile. At that moment I realized that we were at some kind of crossroads. There was a line here somewhere, and if we crossed that, anything could happen.
"Anyway, I need another bath," Lisa said, defusing the situation. The atmosphere was too tense, and an innocent and cooling swim would stop the whole thing from escalating.
Lisa jumped in the water. Topless, but there's not necessarily anything erotic about that? Not crossing any lines, anyway.
"Aren't you coming in?" Lisa laughs, as she splashed water in my direction. I'm still in my swimming shorts, so I just jump in. Arnie gets up and starts undressing. First he takes off his t-shirt. He's quite muscular and tan, so I can't help feeling a bit less of a man. Arnie pulls down his pants, but doesn't stop there. He pulls off his boxers as well, like it's the most natural thing in the world. Lisa gasps, and covers her eyes. But I see her looking between her fingers. Arnies cock isn't erect, but you can really tell that it's quite a large specimen.
Arnie climbs the small cliff behind him, and does an elegant dive into the river. He swims to the end of the river pool, where the water flows rapidly through a small crevice in the rock.
"Have you tried the massage bath over here?" he shouts. "The whirling rapids makes for a real jacuzzi experience!"
"Really?" Lisa swims over to him.
"Look here," Arnie says, "Hold on to this rock and stay upright."
"It's really difficult!" she exclaims. "The stream just pulls me with it."
"I'll hold on to you," Arnie says, and grabs her waist. His hands hold onto her soft curves, not far from her small, pert breasts. "There! Do you feel it?"
"Wow!" Lisa laughs. "It's like a jet in a jacuzzi."
