The temperature had turned muggy and warm so dad took off his shorts and vest to reveal that he was going commando. I had never really paid attention ...to dad’s gentleman bits but this time I noticed that he was nowhere as large as me. When dad drinks he gets antsy and is very irritable. Mom and I know not to irritate him or we won’t hear the end of it. As dad settled in mom looked uncomfortable about sharing the sleeping bag. Given the temperature, she clearly felt overdressed; I could see she. He used to cum while humping or grinding against me. I, on the other hand, touch myself imagining the feel of his touch. He wasn’t that great in foreplay. We were doing it for the experience of it all.”“This continued for a few times, but eventually, I felt this was pointless so, I ignored his pleadings and went back to being normal cousins. It was hard at first because he wanted to do it and, I didn’t.”“I used to ignore him initially but, eventually, he understood and stopped asking me about. Squirting pre-cum what was initially painful began to become bearable and then pleasant. Then I thought about his knot. I became fearful. “No Goldie, please stop” I shouted but he was trying to get his knot into me. It was way too big for suck a small hole and his frustration was getting to him. Finally he gave up and pulled out. I thought that was it but I was so wrong.Now he was so turned on he decided to have another go. Thrusting at me again, this time with a full erection and a growing. We played a few games for an hour or so, and it was just getting dark as we got into my truck. I was about to start it up, and she told me to wait.“Pete, Linda told me to tell you this was no different than us in a hotel, same rules. Is that OK?” She looked into my eyes and moved closer, and I smiled. I moved into the center of the bench seat and slipped her into my lap. My arms went around her waist, and her arms went around my neck as our lips met in a kiss.We kissed for maybe 15 minutes, her.
