It was her first time in Yellowstone, though, so we did make sure we were near the geyser when it erupted. On the other hand, it wasn’t my first tim...e so I made sure we were upwind.We fished the Yellowstone River just below Tower Falls and had fried cutthroat trout for dinner one night. The next day we fished the Madison for a couple of hours in the afternoon and had rainbow trout for dinner. Trish tried her hand at fishing but it didn’t hold her interest. She did help to clean the fish, though,. I pumped my cock hard, grunting a little and breathing up into the warm summer air, “Oh fuck,” I mouthed, “they’re so fucking horny!” And when I looked back to the girls, I guess Sarah had got an inkling that someone was close by, watching. She looked into the laurel bush. Her head tipped to one side; inquisitive. And she smiled. Sarah shimmied forward, putting her knees over Samantha’s arms and shoulders, purring with pleasure as she slid two fingers into the gusset of her thong, and pulled. John, being more dressed, answered the door. "This must be your sister." As we went in, she said, "Hi, I'm Bonnie" and as we passed him, Bonnie slid her hand across his ass and gave him a squeeze. "Nice, which one are you?" "John, and I see that good looks runs in your family." This time, John went up the stairs first, and Bonnie gave him another squeeze. As we entered the bedroom, John introduced Bonnie while Mike, sitting on the bed, continued to stroke his cock. Mike said, "Oh, I like. " Reassured, she snuggled in closer and I pulled the blanket over both of us. Suddenly, while rhythmically pumping my cock, she leaned over and kissed me full on the mouth. I returned it with passion. It was all wet and tongue and she tasted of sex and wine. "You're missing an ear-ring," I said when she pulled back. "Oh, shit!" she said grabbing at her naked earlobe. "So?" I said, raising my eyebrows. She looked at me with a gleam in her eye. "Well, I'm afraid I've been a naughty girl tonight.".
