Yellowstone is a huge park, about 3500 square miles. The road around it is about one hundred forty miles, so we weren't going to see everything in one...day. Actually we had another three nights before we had anywhere in particular to be. I had a reservation at Signal Mountain Lodge in the Grand Teton park on Saturday. This was Tuesday so we decided to just camp and explore Yellowstone for the next three days.That is exactly what we did. We found a campground and picked out a spot and quickly set. "Do you always discuss red-hot monkey sex in front of an eight-year-old?" I enquired mildly.Ginny blushed furiously. "Go sit with your sister in the living room." OK, Ginny, now let's take this inside. No sense entertaining the neighbours, especially when we aren't getting recompensed for doing so."Inside, Ginny turned to me, and advised me again, "You are taking your nieces camping." She doesn't ask — she assumes you'll instantly think it's the greatest idea since sliced bread, without. I pulled off my shoes, socks, shirt, pants, and finally shorts, and my dripping peter popped out, standing hard, and dripping cum. "You're dripping on my rug cocksucker, but don't worry about it." "Flip your pecker up and down a few times, and you'd better not cum!", she said, leaning back against her desk. Her ass was absolutely perfect. She was wearing a very tight business suit, and her hips filled it out magnificently. ____________________________I stood there and looked at her and pulled. "Do you like having such a big cock in your hand?" he whispered again. But this time he started brushing his lips against my ear.I was breathing hard already. "Yes, sir. I have only ever held my own cock. Yours is so much bigger." Keep rubbing it." He started kissing my neck while his hand moved around to the back of my neck. I tried to keep rubbing his cock the best I could, but a combination of the size and his lips on my neck made it difficult.He pulled away. I was afraid I had done.
