We made our way down a stretch of water with a low area dotted with lily pads on one side, and sheer black cliffs on the other. I searched the walls f...or pictographs, but didn’t see any. The waterway gradually opened onto a large lake, which was populated with a number of small islands.“We want to keep to the right of that barren island up ahead,” Ron said as we paddled along.This was another new experience for me. Ron had brought along his own maps, and evidently saw himself as the sole. Her tongue was exploring my mouth and she was rubbing her body all over me. I got hard instantly and my cock was nestled between her thighs. Carol lifted her leg and stroked my cock with her knee and pressed harder into me. We moaned into each others mouth.Carol came up for air and said, "I love you more than anything."I skimmed my hands down her back, caressed her ass and pulled her tighter to me. I started kissing her throat and neck, moving down to suck on her nipples. I looked over her. I waited for a few minutes and looked into the bedroom, to find they had not wasted any time, they were both completely naked, with Ann on top, opposite each other, both going to town eating one another, I walked back out knowing they had not even noticed me, and decided to give them more time alone. I headed into the living room, and placed more wood on the fire, as I thought about what I was happening in the bedroom between my two best friends, I started getting extremely aroused, and so hard. She turned over towards me and we kissed a little and then just lay there enjoying the feeling. We got up and put some pillows against the wall and then leaned back into them and sat there babbling about nothing in particular. There’d been a question on my mind since the first afternoon, and I finally worked up the nerve to ask Tanya.“Why did you invite me back the first day and then spend the weekend teaching me so much about sex? I know I’m okay looking but not really handsome. You had to.
