Changing room fun in public

Three years ago, I was on vacation in the mountains with my father. It was a very hot summer, so we often went to two mountain lakes. My father and I have a very close relationship. We would change into our swimwear right next to each other. We simply swam naked, and there were no other hikers around. One day, we swam naked together all day long. And when we set off hiking after our swim, my father challenged me to go topless. I accepted the challenge and hiked topless. Luckily, we ran into very few people. After that, we went to the spa area. My dad then sat down next to me. At one point, I started touching him. Then I sucked his dick. He came all over my breasts, completely covering them.
Afterward, we left the sauna, and everyone looked at me strangely.
Back in the hotel room, I took a shower. I was touching myself when his father came into the shower. He told me to be a good girl and let him fuck me. I turned around, and he penetrated my pussy. It felt very good. He came inside me.
Afterward, I went to sleep with his cum still inside me. The next morning, everything in my bed felt sticky, but I didn’t care. I put on my thong, my leggings and a sportsbra and we went hiking again.
While hiking, we went swimming in a mountain lake again. This time we weren’t naked—we changed our clothes while covering each other.I said, “Daddy, please fuck me now. In my little asshole.” I sat down on top of him. I had never had anal sex before. It hurt a lot at first, but after a few minutes, it started to feel so good. He came inside my ass.
Afterward, we went back to the bedroom, where I gave him titjob. Then we went to bed together and fell asleep.
In the morning, I woke up because he was rubbing his cock against my pussy. I immediately became aroused again, and he fucked me. After that, packed our things, and drove home.
On the way, we stopped at McDonald’s. We went to the restroom, where he licked my pussy again.
