Ronie and I lived in the mountains and loved to backpack. We went with the same group of people, among them was Frank. We had a trip planned but two people cancelled at the last minute so it was Ronie, Frank and I alone. On our first day out during a rest stop Frank commented on how beautiful Ronie was, and she truly was. A wholesome dark haired girl with dark brown eyes, beautiful body,nice breasts with curvy round hips. We finished the days hike and made camp. That night Ronie and I commented on Frank's admission to her and thought we would see where it would go in the morning. The next morning we got dressed in our tent and Ronie put on her shirt with no bra. I was a western long sleeve shirt with snaps instead of buttons.During breakfast I watched Frank as he was quite taken by Ronie's breasts moving freely under the thin cotton. Her nipples were hard and showed prominently. After breakfast it warmed up and we thought we would get some sun and maybe swim in the lake we camped at. Ronie asked Frank if he would join us. We found a nice sandy beach and Ronie spread her towel. She then turned toward us and pulled the snaps loose opening her shirt and exposing her creamy soft breasts. Frank froze and gazed saying nothing. Ronie had beautiful firm breasts with large red nipples. While Frank was still motionless struck by her beauty, Ronie unbuttoned her Wranglers and slipped them over her hips exposing a soft, dark patch of hair. Frank started to come to his senses and looked over at me where I had a smile from his reaction. Ronie laid down on her towel and asked Frank if he would join her. Frank hurriedly took off his clothes and moved over to her. He laid beside her and they started to kiss and caress each other. Frank Kissed her lips and breasts and moved his hand down between her legs feeling her wetness. After a short time Ronie took Frank's waist in her hands and softly motioned him to move on top of her. Her legs were opened as wide as I had ever seen them as he settled in between them. He found Ronie's soft spot and slipped inside with urgency, Ronie said slow down you're too deep and Frank backed out with just the tip of his cock inside her. He slowly pumped pulling her creamy juices out with each stroke. Finally Ronie had relaxed enough that he was fully inside her. They pumped in rhythm with eyes closed and enjoyed the moment. Frank got up a little and moved his arms under Ronie's legs pushing them up to get deeper. She responded with soft moans of pleasure. Frank picked up the pace driving himself into her finally with such force that his balls slapped loudly against Ronie. This drove Ronie crazy and in a short time she stiffened and started moaning loudly as she came. Her vagina pulsed grabbing Frank's hardness and soon Frank also Stiffened and settled deep into her. His balls were pulsing on Ronies buttocks as he pumped a huge, creamy load deep into her. Ronie laid back taking it all inside her. They laid coupled for a moment and then Frank moved off. Ronie got up on her elbows with one leg spread and a look of satisfaction on her face. Soon a milky white cream started to form as Frank was oozing out of her pussy. By now I had my clothes off too and I moved in to that creamy spot and slipped myself into the wettest pussy I had ever experienced. We fucked for a short time as I couldn't last long after watching Frank fuck my wife. Frank sat beside us and Ronie stroked him back to hardness while I was busy with her. After I finished Frank was ready for another round. He rolled her over, lifted her hips and entered her from the back.He fucked her for a long time this time as he had more stamina. Ronie enjoyed the angles from the rear and occasionally would pound herself against him until he would beg her to stop. Finally he stiffened and buried his cock deep in her with another creamy load. She took it all with a look of pure joy. When they were done we laid around for a bit and then decided to go for a short swim. When Ronie stood to go to the water the three loads of cum ran down to her knees. She then reached down and rubbed the cream along her legs and back up to her pussy until it glistened with cum all the time looking at us with a huge smile. The rest of the trip Ronie got fucked every way possible by Frank and me. Sometimes together other times I went hiking or fishing and they would fuck all the time I was gone. We had to stay over a day at one place because Ronie was so sore she couldn't walk far. We had other trips with the group but none were as good as this one.
