We had started out with plans for a picnic but Kelly had purchased a two-person tent in the late fall and she wanted to try it out.We met at our usual...rendezvous to leave her car. We moved her things to my SUV and headed to the mountain. This was the Memorial Day weekend. The highway was crowded. We planned to go back to the camping area we had used that Fall. It was down a dirt road, off the highway and fairly secluded. When we got there, there was a group already camped in our spot; how dare. Her other hand snaked behind her and wrapped itself around my member and roughly wanked me at the same time as Troy. I felt so dirty and decided to try something. I spat on my finger and circled it around her anus, gently easing it into her arse, moving it gently back and forth, Maria groaned with pleasure and I decided to push my finger in further up to the knuckle. “Oh god your finger feels so good up my arse.” Usually Maria doesn’t do bum sex so I am pleasantly surprised. After five minutes. He told me to open my mouth and suck his penis, I take it in my mouth and begin to suck it slowly at first like sucking on a popsicle. As I start sucking he starts too, starts bobbing his head up and down on my penis making me feel good, as I make him feel good. We're so caught up in sucking each other, that we don't notice his older brother watching us sucking each other. He's at the door only in his underwear stroking himself slowly and steadily. We stop after he lets out a deliberate moan. The sun was shining, temps were in the high 60's to low 70's, perfect weather for a trip to the hot springs.I arrived about 9am and wandered around the springs since there were very few people present. It is a legal nude hot springs out in nature, one of the few left, and always thrilling to feel the sun and breeze on my nude body. After an hour or so more people started showing up, as well as a few groups of people... mixed couples, singles, several guys, and a couple groups of women. Few were.
